Abstract

The invention discloses a connector insertion test circuit which is used for testing whether a movable connector is inserted on an onboard connector correctly or not, and comprises two movable test pins, two onboard test pins, a test power supply and a light-emitting diode, wherein, the two movable test pins are arranged at the two sides of the pin of the movable connector; and one end of the movable test pin is electrically connected by a wire; the two onboard test pins are arranged at the two sides of the pin of the onboard connector and correspond to the two movable test pins; the test power supply is electrically connected with the other end of the pin of the movable test pin; one end of the light-emitting diode is electrically connected with the other end of the other movable test pin; and the other end of the light-emitting diode is earthed. Compared with the prior art, for whether a movable connector is inserted on the onboard connector correctly or not, the connector insertion test circuit is only needed to test, thus the result can be obtained, while a reinserting manner is not needed, the insertion test of a large amount of connectors is more convenient and faster.

Description

Connector inserts test circuit

[technical field]

The relevant a kind of test circuit of the present invention is meant that especially a kind of connector inserts test circuit.

[background technology]

There are a lot of flexible jumpers to insert connector on the plate in computer inside; and whether correctly insert connector on the plate (for example oblique cutting and part insert) for flexible jumper at present; can't well judge; in order to understand the insertion situation of flexible jumper; usually use hand and go to detect in person, insert again again.

Yet, come the test activity connector whether to officially enroll for aforesaid way and insert connector on the plate, slotting cumbersome again on the one hand, in addition, test a large amount of connectors if desired and whether correctly insert, workload is bigger especially.

In view of this, be necessary to provide a kind of connector to insert test circuit in fact, whether insert normally for connector, only need to test, can obtain the result, and need not use the mode of inserting again by this circuit, insert test for a large amount of connectors, convenient and swift especially.

[summary of the invention]

Therefore, the object of the present invention is to provide a kind of connector to insert test circuit, whether insert normally for connector, only need to test, can obtain the result, and need not use the mode of inserting again by this circuit, insert test for a large amount of connectors, convenient and swift especially.

For reaching above-mentioned purpose, connector of the present invention inserts test circuit, is used for the test activity connector and whether correctly inserts connector on the plate, and this circuit comprises:

Two activity test pin, it is located at the both sides of the existing pin of flexible jumper, and this two activities test pin, one end is electrically connected by lead;

Test pin on two plates, it is located at the both sides of the existing pin of connector on the plate and corresponding with above-mentioned two activity test pin;

One testing power supply, itself and an above-mentioned activity test pin other end electrically connect;

One light emitting diode, one end and above-mentioned another activity test pin other end electrically connect this light emitting diode other end ground connection.

Compared to prior art, utilize connector of the present invention to insert test circuit, whether normally insert connector on the plate for flexible jumper, only need to test by this circuit, can obtain the result, and need not use the mode of inserting again, and insert test for a large amount of connectors, convenient and swift especially.

For purpose of the present invention, structural attitude and function thereof are had further understanding, conjunction with figs. is described in detail as follows now:

[description of drawings]

Fig. 1 illustrates the structural representation that connector of the present invention inserts test circuit one preferred embodiment.

Fig. 2 illustrates the circuit diagram that connector of the present invention inserts test circuit one preferred embodiment.

Fig. 3 illustrates the application circuit that connector of the present invention inserts test circuit one preferred embodiment.

[embodiment]

See also Fig. 1, Fig. 2, it illustrates Fig. 1 respectively and illustrates structural representation, the connector of the present invention that connector of the present invention inserts test circuit one preferred embodiment and insert the circuit diagram of test circuit one preferred embodiment.

Connector of the present invention inserts test circuit, is used for test activity connector 10 and whether correctly inserts connector 20 on the plate, and this circuit comprises:

Two activity test pin 11, it is located at the both sides of flexible jumper 10 existing pins, and these two activities test pin, 11 1 ends are electrically connected by lead 12;

Test pin 21 on two plates, and it is located at the both sides of the 20 existing pins of connector on the plate and corresponding with above-mentioned two activity test pin 11;

One testing power supply 30, itself and an above-mentioned activity test pin 11 other ends electrically connect;

One light emitting diode 40, one end and above-mentioned another activity test pin 11 other ends electrically connect these light emitting diode 40 other end ground connection.

If light emitting diode 40 luminous then flexible jumpers 10 normally insert, if light emitting diode 40 is not luminous, then flexible jumper 10 does not normally insert.

Please consult Fig. 3 again, Fig. 3 illustrates the application circuit that connector of the present invention inserts test circuit one preferred embodiment.

Whether correctly insert connector 20 on the plate for two or more flexible jumpers 10 of test, the end that one end that one flexible jumper 10 can be used for connecting testing power supply 30 and another flexible jumper 10 are used for being connected light emitting diode 40 electrically connects, if light emitting diode 40 luminous then a plurality of flexible jumpers 10 all normally insert, if light emitting diode 40 is not luminous, then there is one or more flexible jumper 10 normally not insert, thereby reaches test purpose.

Utilize connector of the present invention to insert test circuit, whether normally insert connector on the plate, only need to test by this circuit for flexible jumper, can obtain the result, and need not use the mode of inserting again, and insert test for a large amount of connectors, convenient and swift especially.

Claims (1)
