The auxiliary positioning device comprises a holding body which can hold both sides of the circuit board and a retaining mechanism capable of retaining the inserting-pulling stroke of the circuit board, wherein the circuit board inserted on the slot connector can be buckled at a preset position without swinging or being disengaged from the connector by the retaining mechanism.
Description
The present invention relates to a kind of auxiliary locator, be in particular to relate to and a kind ofly can make the better auxiliary positioning device for circuit board of circuit board polarization that is plugged on the connector.
The design of computer product just tending to gently, thin, short, little, therefore how under the existing configuration of computer, to dwindle the space, be information industry problem anxious to be solved.With host computer (CPU), traditional mode is directly to be welded in CPU on the main substrate, yet present trend is the space that utilizes on the circuit board, CPU is welded on the circuit board, directly utilize circuit board to be plugged on the connector, realize electrical connection, thereby save the configuration space of whole main substrate.Yet such change is a kind of new burden for the connector that butt joint is provided, specifically, because the aspect ratio connector of circuit board own is high a lot, for shambling, the circuit board after preventing to plant can cause the circuit instant cut-off under bad operational environment, influence the transmission of signal stabilization, the both sides of connector directly are provided with holding unit at present, as United States Patent (USP) the 3rd, 993,390,4,057,879,4,070,801,4,084,874 and 5,407, No. 36 etc., perhaps beyond add mode holding unit and connector branch are arranged after mutual again fit, as United States Patent (USP) the 3rd, 829,741,2,825, No. 037 etc.Yet above-mentioned this holding unit is at most only considered stressed that circuit board is rolled, and stressed as vertical vibration for above-below direction works hardly.Therefore, after circuit board weldering system central processing unit (even development makes radiator, negative fan etc. in the lump later on), not only weight increases, and stressed direction is also amesiality, in case be inserted in above-mentioned existing connector, the vibration environment under work, rocking about both can't having born, for up-down vibration (particularly vibration vertically) can't bear especially.
The object of the present invention is to provide a kind of device that is used for the auxiliary circuit board location, this auxiliary locator can be located the circuit board that is inserted on the connector up and down really, preventing that circuit board rocks under the environment of vibration, even break away from electric connector, guarantee the stable transfer of signal.
The object of the present invention is achieved like this, and a kind of auxiliary positioning device for circuit board promptly is provided, and is used for the circuit board that is plugged on the connector is also located, and described auxiliary locator comprises: a cramping body, be located on the main substrate, and insert and put the both sides of circuit board; One deduction mechanism, plant direction with respect to circuit board, parallelly buckle into and vertically support to end on the plug stroke of circuit board, it comprises a deduction arm and and replys part, described deduction arm is located on the cramping body, one end is a control end, the other end is for only supporting and separating end of thread, describedly support to end and separate controlling of end of thread mat control end, circuit board is only supported and the control of triping, thereby, the insert and put effect of the described cramping body of mat about to circuit board, and deduction mechanism ends supporting of circuit board top, and the circuit board stably fastening that will be inserted in connector is in both allocations, with the situation generation of avoiding rocking or breaking away from.
The advantage of auxiliary positioning device for circuit board of the present invention is that it makes circuit board locate reliably at each different directions, can make it to be suitable for various applied field and merge connection firmly, and transmission signals is reliable, and practicality is good.
