The utility model solves the technical problem that in the prior art, when the circuit board contacts are tested, a testing plug is plugged and unplugged repeatedly, resulting in low testing efficiency and factitious misoperation. The utility model has the benefits that the testing plug only needs to be connected with an electron switch and dispenses with frequent plugging, so as to prolong the service life; and the electron switch automatically controls the state of the switch contacts to realize the test on different line contacts, which is efficient and accurate, and misoperation caused by human factors is avoided.

Description

A kind of non-plug circuit board testing device

Technical field

The utility model belongs to the Electrical Measurement Technology field, is specifically related to a kind of non-plug circuit board testing device.

Background technology

In the prior art, when a plurality of contacts of the same circuit of circuit board are tested, need manually test plug is connected on each contact of this circuit and test, human cost is big, and testing efficiency is low; When a plurality of contacts of another circuit are tested, need manually test plug to be connected on each contact of another circuit again, very easily introduce human factor and cause maloperation; In addition, test plug has shortened serviceable life under the situation of frequent plug.

The utility model content

The technical matters that the utility model will solve is: when prior art is tested circuit board contact, need utilize test plug to repeat plug, testing efficiency is low, and being prone to introduce the people is maloperation.

The technical scheme of the utility model is described below:

The non-plug circuit board testing device of the utility model comprises 1# to 50# totally 50 contacts; Wherein 13# contact and 29# contact internal communication and ground connection; Above-mentioned contacts grouped is carried out internal communication; Draw several switch contacts, switch contact is not connected to two common port or the non-common ports of putting switch of four blade respectively.

As preferred version; Circuit board contact 1#, 14#, 16# are communicated with formation switch contact I#; Circuit board contact 2#, 30#, 32# are communicated with formation switch contact II#; Circuit board contact 15#, 31#, 46#, 48# are communicated with formation switch contact III#, circuit board contact 47#, 49# are communicated with formation switch contact IV#; Switch contact I#, switch contact II#, switch contact III# and switch contact IV# are connected to the two common ports of putting switch of four blade successively; Contact 17#, 33#, 29#, 50# as switch contact 17#, switch contact 33#, switch contact 29#, switch contact 50#, are connected to the two 1. number non-common ports of switch of putting of four blade that close contact III# and corresponding the same side, switch contact IV# position respectively with switch contact I#, switch contact II#, switch; Four blade is two puts 2. number four the contact conductings of non-common port of switch opposite side.

The beneficial effect of the utility model is:

This device is arranged connection according to circuit board contact place circuit, draws the switch contact than the remarkable minimizing of number of contacts, utilizes the connected of electronic switch CS contact.In the test process, test plug only needs to link to each other with electronic switch, need not frequent plug, has prolonged serviceable life; The state of electronic switch automatic control switch contact can be realized the test of different line contact, and efficiently and accurately is avoided because human factor is introduced maloperation.

Embodiment

Below in conjunction with accompanying drawing and embodiment the non-plug circuit board testing device of the utility model is elaborated.

In the present embodiment, 50 contacts are arranged on the circuit board, wherein 13# contact and 29# contact internal communication.

As shown in Figure 1, the contact internal communication circuit that needs test plug A to measure is:

1#-14#-16#-17#；

2#-30#-32#-33#；

13#-15#-29#-31#-46#-48#-GND；

47#-49#-50#。

As shown in Figure 2, the contact internal communication circuit that needs test plug B to measure is:

1#-2#-14#-15#-16#-30#-31#-32#-46#-47#-48#-49#。

As shown in Figure 3, the contact internal communication circuit of test plug A is divided into two groups of switch contacts shown in the following table:

First group	Be communicated with	Second group
			Switch contact I# (1#-14#-16#)	←→	Switch contact 17#
Switch contact II# (2#-30#-32#)	←→	Switch contact 33#
			Switch contact III# (15#-31#-46#-48#)	←→	Switch contact 29#
Switch contact IV# (47#-49#)	←→	Switch contact 50#

Need to prove for last table, because 13# contact and 29# contact internal communication in the present embodiment, so 13# contact and 29# contact all can be considered same contact under all states.

Above-mentioned switch contact I# is communicated with switch contact 17#, switch contact II# is communicated with switch contact 33#, switch contact III# is communicated with switch contact 29#, switch contact IV# is communicated with switch contact 50#, is four contact circuits that test plug A need test.

Above-mentioned switch contact I#, switch contact II#, switch contact III# and switch contact IV# are connected, and are the contact circuit that test plug B need test.

The contact that belongs to same switch contact on the circuit board is connected together, draw above-mentioned 8 switch contacts.As shown in Figure 4, wherein switch contact I#, switch contact II#, switch contact III# and switch contact IV# are connected to the two common ports of putting switch of four blade successively; Switch contact 17#, switch contact 33#, switch contact 29# and switch contact 50# be connected to four blade two put switch respectively with the two 1. number non-common ports of switch of putting of the four blade of switch contact I#, switch contact II#, the corresponding the same side of switch contact III# and switch contact IV# position; Four blade is two puts 2. number four the contact conductings of non-common port of switch opposite side.When common port when 1. number non-common port contacts, four contact circuits need testing for test plug A; When the 2. number non-common port contact of common port, a contact circuit need testing for test plug B.

The structural representation of present embodiment is as shown in Figure 5, when the electronics four blade is two when putting the switch common port and 1. number non-common port contacting, is the internal wiring of test plug A; When the electronics four blade is two when putting the switch common port and 2. number non-common port contacting, be the internal wiring of test plug B.
