Abstract
The utility model provides a testing device for fine-pitch arranged pins on a PCB (Printed Circuit Board). The testing device comprises a pin bed; the pin bed is provided with PCB positioning pins; a socket positioning frame corresponding to a socket is arranged on a panel of the pin bed; probes corresponding to plugged pins in the socket are arranged in the socket positioning frame; two adjacent probes are separated from each other through a probe positioning frame; and the probes correspond to a testing circuit connected onto the testing device. The testing device for the fine-pitch arranged pins on the PCB can be used for testing high-density sockets, and the problem of short circuit arising from the contact between two adjacent pins is solved.
Description
[technical field]
The utility model relates to the proving installation of socket on a kind of pcb board, the proving installation of thin space row pin on particularly a kind of pcb board.
[background technology]
In PCB test industry, a kind of test point rules of standard universal are arranged, four density and dual density, each test point must be connected with waiting test circuit.
Existing P CB board measuring method all is through line the test circuit pin directly to be welded on the test contact point, carries out test job, yet present circuit board integrated level is increasingly high, and solder joint is more and more littler, and density is more and more closeer.The arrangement space of pcb board is more and more littler.Draw test point difficulty all the more.
Therefore existing proving installation is difficult to adapt to highdensity test, and perhaps because test spacing when too near, needle guard bends easily, causes burning device on the pcb board.
[summary of the invention]
The technical matters that the utility model will solve is to provide the row of thin space on a kind of pcb board the proving installation of pin, and it can be used in the test of high density socket, and has overcome that contact causes problem of short-circuit between adjacent two pins.
The utility model is achieved in that the proving installation of thin space row pin on a kind of pcb board; It comprises a needle-bar; Said needle-bar is provided with the PCB register pin, and the panel of said needle-bar is provided with and the corresponding socket posting of said socket, be provided with in the said socket posting with socket in the corresponding probe of contact pin; Isolated through the probe posting between adjacent two probes, said probe correspondence is connected in the test circuit on the proving installation.
Further, the top of said probe is set to and the big or small corresponding infundibulate of the shape of contact pin.
The advantage of the utility model is:
The utility model adopts the socket posting, realizes the Primary Location of probe and socket contact pin, and the top of said probe is set to the corresponding infundibulate of shape size with contact pin; Make that contact pin and corresponding probe can be corresponding one by one; The utility model has used the probe posting, and corresponding probe and contact pin all are retracted in the probe posting during test, guarantees to isolate fully between adjacent two pins; Guarantee that adjacent probe does not contact; Therefore the present invention need not to draw test point, can directly test the high density socket, and prevent to burn device on the pcb board.
[description of drawings]
Combine embodiment that the utility model is further described with reference to the accompanying drawings.
Fig. 1 is the cross-sectional view of the utility model.
[embodiment]
See also shown in Figure 1ly, the embodiment of the utility model is carried out detailed explanation.
Like Fig. 1; The proving installation of thin space row pin on a kind of pcb board of the utility model; It comprises a needle-bar 1, and said needle-bar 1 is provided with PCB register pin 2, and the panel of said needle-bar 1 is provided with and said socket 3 corresponding socket postings 4; Be provided with in the said socket posting 4 with socket 3 in contact pin 5 corresponding probes 6, the top of said probe 6 is set to and the corresponding infundibulate of the shape of contact pin 5 size.Isolated through probe posting 7 between adjacent two probes 6, said probe 6 correspondences are connected in the test circuit on the proving installation.
PCB8 to be measured is placed on needle-bar 1 panel; When beginning to test, PCB8 to be measured is pressed on needle-bar 1 panel closely, the elasticity of PCB register pin 2 is cancelled; At this moment; The corresponding one by one contact of probe 6 in the socket posting 4 on contact pin 5 in the socket 3 and the needle-bar 1, and the corresponding point on the switch card (the main test cell of proving installation) on probe 6 and the needle-bar 1 contacts, and promptly between PCB8 to be measured and switch card, has formed a loop.At this moment, proving installation just can have been judged the electric property of this PCB8 to be measured.
In test,, make that the contact pin 5 in the socket 3 reaches Primary Location with probe 6 through the pre-determined bit of socket posting 4; Because the top of said probe 6 is set to the corresponding infundibulate of shape size with contact pin 5, contact pin 5 can get in the infundibulate on corresponding probe 6 tops, so contact pin 5 can be corresponding one by one with corresponding probe 6.
When PCB8 to be measured was continued to depress, corresponding probe 6 all was retracted in the probe posting 7 with contact pin 5, thereby had guaranteed that adjacent two contact pins 5 or probe 6 can short circuits, the influence test.
The utility model test is applicable to the test of high density socket on the pcb board, such as the test of 1.27 spacings lead-in wire.
The above; Be merely the utility model preferred embodiment; So can not limit the scope that the utility model is implemented according to this, the equivalence of promptly doing according to the utility model claim and description changes and modifies, and all should still belong in the scope that the utility model contains.
