Description
- 1. Field of the Invention
- The present invention relates to an electrical connector, and more particularly to an electrical connector having a detachable pick-up cap.
- 2. Description of Related Art
- Electrical connectors including pick-up means for facilitating picking up and positioning by a pick-up machine such as a vacuum suction nozzle or the like are well-known. For example, U.S. Pat. No. 5,688,133 discloses such a connector with a pick-up cap. The pick-up cap comprises a flat cover plate and pairs of resilient legs descending downwardly from edges of the cover plate to engage sidewalls of the connector. The legs include main legs gripping outside of the sidewalls and auxiliary legs abutting against inner surfaces of the sidewalls. With this arrangement, each sidewall of the connector is, in effect, sandwiched between the main and auxiliary legs to be picked up via the force applied thereto by the legs while the pick-up cap is taken up by suction of a vacuum suction nozzle upon the flat cover plate thereof. Then the connector is transferred to a printed circuit board (PCB) and positioning them in a preselected position for soldering. The pick-up cap remains in place upon the connector until after it is joined to the PCB by soldering. So, the sidewalls of the connector are under the gripping force applied by the legs of the pick-up cap all the while during passing through the reflow vessel for soldering. As the auxiliary legs punched out of the main legs are shorter than the main legs, the auxiliary legs and the main legs respectively abut against the sidewalls on their upper portions and lower portions. As a result, the main legs press the sidewalls slightly inwardly while the auxiliary legs press the sidewalls slightly outwardly, which may cause deformation or warpage of the connector on the sidewalls. If once such deformation or warpage occur, it will potentially result in misalignment and misengagment between the connector and its mating connector.
- U.S. Pat. No. 6,019,617 discloses another conventional connector with a pick-up cap. The pick-up cap disclosed therein has two pairs of resilient legs each provided with a hook-like end to be forced into channel formed in sidewall of the connector. In the process of the resilient legs being forced into the channel, the hook-like ends thereof apply a force to the sidewalls, but that force is in a longitudinal direction along the sidewalls and will rarely cause deformation of the connector. Once the legs detained in the channels, the pick-up cap will not apply force to the sidewalls anymore, except a hooking force upwardly along the sidewalls when the pick-up cap is taken up by suction of a vacuum suction nozzle and the connector is hooked up by the pick-up cap. Thus the connector will rarely suffer deformation or warpage while passing through the reflow vessel for soldering. However, this kind of pick-up cap requires channels to be defined in sidewalls of the connector for its legs with hook-like ends, which not only complicates the machining procedure of the connector but also weakens the sidewalls of the connector.
- Therefore, to overcome the disadvantages of the prior arts, an improved connector with a pick-up cap is desired.
- An object of the present invention is to provide a connector having a pick-up cap which farthest reduces the deformation in the connector while passing through a reflow vessel.
- Another object of the present invention is to provide a connector with a pick-up cap, which is easy to produce and assemble.
- In order to achieve above-mentioned objects, an electrical connector in accordance with a preferred embodiment of the present invention includes an housing formed with a mating slot and defining a mating direction; a plurality of terminals loaded in the housing, each terminal provided with a resilient contact portion protruding into the mating slot and enabled to deflect along a direction substantially perpendicular to the mating direction; and a pick-up device having a main body with a smooth upper surface for vacuum section and a retaining portion extending down from the main body and inserted into the mating slot. The retaining portion is provided with a nose pushed through the contact portions to engage with the contact portions along the mating direction.
- Other objects, advantages and novel features of the present invention will become more apparent from the following detailed description of the present embodiment when taken in conjunction with the accompanying drawings.
-
FIG. 1 is an assembled view of a connector with a pick-up cap in accordance with the preferred embodiment of the present invention; -
FIG. 2 is an exploded perspective view of the connector ofFIG. 1 ; -
FIG. 3 is an exploded perspective view of the connector ofFIG. 1 taken from another aspect; -
FIG. 4 is a perspective view of the pick-up cap ofFIG. 1 ; -
FIG. 5 is a cross-sectional view of the connector ofFIG. 1 taken along line 5-5; and -
FIG. 6 is a cross-sectional view of the connector ofFIG. 1 taken along line 6-6. - Reference will now be made to the drawing figures to describe the preferred embodiment of the present invention in detail. Referring to
FIGS. 1-3 , a connector in accordance with the present invention comprises aninsulative housing 1, a plurality ofterminals 2 loaded in thehousing 1, ashell 3 attached to a periphery of thehousing 1, and a pick-up cap 4 detachably assembled to thehousing 1. - The
housing 1 that is of a rectangular structure has a pair of oppositelongitudinal sidewalls slot 12 therebetween opening to amating face 11 of thehousing 1 to receive a mating connector. One of thesidewalls 13 defines a plurality of terminal-receiving grooves, each of which receives oneterminal 2. Theterminal 2 has acrooked head 21 protruding into themating slot 12 to serve as a contact portion for electrically contacting a conductor on the mating connector and atail 22 horizontally coming out of thehousing 1 to serves as a solder portion to be soldered to a printed circuit board (PCB). Turning toFIG. 5 , to join thecrooked head 21 and the horizontallytail 22, theterminal 2 further has a S-shaped body portion (not labeled), which enable thecontact portion 21 to perform resilience in a breadth direction. Thecrooked head 21 gives alower section 23 of theterminal 2 closely extending therefrom, that is a joint of thecrooked head 21 and the body portion, a concavity appearance. - Referring to
FIG. 3 , theshell 3 attached on the periphery of thehousing 1 has a pair ofstooped pieces 31 bent down onto an inner surface of thesidewall 14. That pair ofpieces 31 are comparted by an inwardly bulged middle of thesidewall 14 in a longitudinal direction, and each has arib 311 thereon protruding into themating slot 12. - Referring to
FIGS. 2-4 , whereinFIG. 4 shows the pick-up cap 4 being inverted, the pick-up cap 4 comprises aflat cover plate 41 having a smoothupper surface 411 for receiving vacuum suction from a pick-up machine (not shown) and aretaining leg 42 extending downwardly from thecover plate 41 to be inserted into themating slot 12 of thehousing 1. From afirst side 421 of theretaining leg 42 project a pair ofrims 423 at its edge remote from thecover plate 41. Oppositely, there is aprotuberant block 424 formed at the oppositesecond side 422 of theretaining leg 42 and extending from an end of theretaining plate 42 adjacent to thecover plate 41 to the other end remote from thecover plate 41. Wherein along a longitudinal direction of theretaining leg 42 corresponding to that of theelongated mating slot 12, theblock 424 is located in middle of the pair ofrims 423. Additionally, thecover plate 41 defines a pair ofaperture 410 therethrough corresponding to therims 423 for purpose of mold-pulling. - Referring to
FIGS. 5 and 6 together, in use, the pick-up cap 4 is assembled to thehousing 1 with theretaining leg 42 thereof inserted into themating slot 12 and thecover plate 41 thereof covering upon themating face 11. During the inserting process, theblock 424 on theretaining leg 42 slides into themating slot 12 from a gap between the pair ofribs 311 to be locked therebetween for preventing the pick-up cap 4 from longitudinally moving, and therims 423 pushes through thecontact portions 21 of theterminals 2 to be detained at theconcavity 23 thereof. Thus, theconnector 100 can be picked up via an upward force on thecontact portions 21 applied by therims 423 of the pick-up cap 4. Theretaining leg 42 of the pick-up cap 4 is sized to being fitly received in themating slot 12 but not inflicting a force onto thesidewalls retaining leg 42 in width is not larger than that of themating slot 12. So, when theconnector 100 is taken into a reflow vessel for soldering via the pick-up cap 4, thesidewalls - The disclosure is illustrative only, changes may made in detail, especially in matter of shape, size, and arrangement of parts within the principles of the invention.
