Definitions
- the present invention concerns an electrical connector equipped with two connector halves which are respectively mounted on different boards, and which connect these boards to each other.
- PCB's printed circuit boards
- Such electrical connectors as disclosed in U.S. Patent No. 5,224,866 are equipped with a plug connector and a cap connector which are mounted on different boards, and which are connected to each other.
- the PCB's are connected to each other by connecting the plug connector and cap connector.
- the plug connector and cap connector each have a plurality of contacts, and a housing in which these contacts are lined up at a given pitch.
- the contacts lined up in the housing of the plug connector possess spring forces, so that when the plug connector and cap connector are connected, the contacts lined up in the respective housings are caused to contact each other with a given force as a result of these spring forces, thus establishing an electrical connection.
- the contacts have been a tendency for the contacts to become smaller, and for the pitch at which the contacts are lined up to become narrower.
- the contacts have also been a tendency for the contacts to become shorter, in order to reduce the distance between the connected boards when the boards are connected face-to-face by such an electrical connector.
- the object of the present invention is to provide an electrical connector which makes it possible to cause the contacts to contact each other with a high contact pressure even if the contacts are made smaller or shorter.
- Figures 12-14 illustrate the cap connector in a second embodiment of the electrical connector of the present invention.
- Figure 12 is a plan view
- Figure 13 is a side view
- Figure 14 is an end view.
- Figure 15 is a cross-sectional view of the cap connector shown in Figures 12-14.
- Figure 19 is a side view which illustrates the cap connector in a fourth embodiment of the electrical connector of the present invention.
- the electrical connector 10 ( Figure 11) has a plug connector 20 and a cap connector 60 which are connected to each other.
- the plug connector 20 is mounted on a board 12, and the cap connector 60 is mounted on a board 14.
- the boards 12 and 14 are connected to each other .face-to-face as shown in Figure 11.
- Contacts 40 are comprised of contact sections 41 including S-shaped first spring members 42 which have two bent portions 42a and 42b, second spring members 44 which have contact projections 44a that electrically contact the contact sections 82 of contacts 80 described later, and termination sections 46 which are soldered to conductive pads 12d on the board 12.
- the contact legs 42c of the first spring members 42 substantially contact the wall surfaces 38a and 38b, while the second spring members 44 via contact projections 44a contact the contact sections 82 of the contacts 80.
- the contacts 40 are formed by stamping from single metal plates, which are superior in terms of conductivity and spring characteristics.
- the first and second spring members 42 and 44 of the contacts 40 are clamped between the wall surfaces 38a and 38b and the contact sections 82 of the contacts 80. Furthermore, when the contact projections 44a of the second spring members 44 are pressed against the contact sections 82 of the contacts 80, the first and second spring members 42 and 44 apply a force on the contacts 80. Thus, when the plug connector 20 and cap connector 60 are connected, the contacts 40 are clamped between the wall surfaces 38a and 38b and the contacts 80, and are strongly pressed against both the wall surfaces 38a and 38b and contacts 80.
- the electrical connector of the second embodiment is characterized by the shape of the cap connector.
- the plug connector has the same shape as the plug connector in the first embodiment. Accordingly, the cap connector will be described here.
- the cap connector 90 is equipped with a housing 100 and contacts 120.
- the contacts 120 are lined up in two rows along the length of the housing 100. Compared to the contacts 80 of the cap connector 60 shown in Figures 6-9, the contacts 120 are longer, with a length of approximately 9.00 mm.
- the housing 100 is equipped with posts 102 and 104 which are respectively inserted into post holes 14a and 14b formed in the board 14, and a metal-fastening fitting 106 which is soldered to a fastening pad 14c on the board 14.
- side walls 108 extend in the direction of the length of the housing 100 and are formed with openings 108a. These openings are a characteristic feature of the cap connector 90. The reason for forming the openings 108a will be described below.
- the electrical connector 128 of the third embodiment is characterized by shield plates 170 which are attached to the side surfaces of walls 158 of the housing 152 of the cap connector 150, and by the shape of the ground contacts among the contacts of the plug connector.
- the housing 152 of the cap connector 150 has projecting portions 159, and grooves 160 which accommodate the projecting portions 138 of housing 132 at which the contact sections Si and extensions 134a are located.
- the assembly process is as follows: The shield plates 170 are first attached to the housing 152 of the cap connector 150, after which the contacts 154 and 156 are positioned into the housing 152. Soldering is performed only when the cap connector 150 is attached to the board. Dimples 174 are formed in the shield plate 170, and these dimples 174 electrically contact the extensions 134a of the ground contacts 134. However, it would also be possible to omit the dimples 174. In the electrical connector of this third embodiment, as was described above, the respective ground contacts 134 and 154 can easily be connected by attaching a single shield plate 170 to the housing 152 of the cap connector 150.
- Figure 19 illustrates a fourth embodiment of the electrical connector of the present invention.
- the difference between this electrical connector and the electrical connector of the third embodiment lies in the shape of the shield plates.
- no projections are formed in the tongue members in order to prevent sagging of the slots 182.
- An effect similar to that obtained using the shield plates 170 shown in Figure 16 can also be obtained using these shield plates 180.
- first contacts are lined up in two rows so that the first and second spring members are mutually symmetrical in the opposing rows, the respective forces from the wall surfaces and the second contacts are balanced between the two rows, so that the first contacts and second contacts can be electrically connected to each other with a high, well-balanced contact pressure, thus making it possible to obtain an electrical connector which provides a secure electrical connection.
