Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connector.

[0002]

2. Description of the Related Art In recent years, surface mounting type parts have become mainstream as the parts mounted on a circuit board have become popular. As a matter of course, a surface mount type connector is also used as a connector for electrical connection with components outside the board. Here, a conventional connector will be described with reference to FIGS.

FIG. 4 is an external view of a conventional connector.
Is a connector pin having a foot 1a for connecting to a conductive pattern on a mounting board and a socket 1b provided on the opposite side (not shown) of the foot, and 2 is a resin-made connector body for holding the connector pin 1. is there.

Usually, after mounting the connector, a mounting confirmation test is conducted by a continuity test in order to check whether the connector is electrically connected to the mounting board. Here, a conventional method of confirming the mounting of the connector will be described with reference to FIGS.

The first method of the connector mounting confirmation test is to use a test board. As shown in FIG. 5, in order to confirm the soldering of the connector pin 1 and the mounting board 3,
After confirming a short circuit between the connector pin 1 and the conductive pattern 4 on the mounting board 3, a person manually connects the test board 5 to the socket 1b of the connector pin 1 to test the conductive pattern 4 on the mounting board 3 and the test. Between the contacts 6 on the substrate 5,
Two operations of confirming the presence or absence of continuity using the inspection needle 7 and the function tester 8 were performed.

A second method for checking the mounting of the connector uses a test needle 7 and a function tester 8 for checking whether or not there is conduction between the foot of the connector pin 1 and the conductive pattern 4, as shown in FIG. This is done by omitting the trouble of connecting the test board 5 of the first method.

[0007]

However, the first method as described above requires a work step in which a person manually connects the test board 5 to the socket of the connector pin 1 before testing.

In the second method, the legs 1a of the connector pins 1 protruding from the connector body 2 have a very narrow pitch, or the legs 1a of the connector pins 1 are exposed too much for miniaturization. In a connector that does not have a high positioning accuracy, it is necessary to use an expensive inspection needle 7 because the inspection needle 7 requires high positioning accuracy.

As described above, since the conventional connector is not designed in consideration of the mounting confirmation test, the mounting confirmation test requires extra steps and costs.

The present invention solves the above-mentioned problems and eliminates the need for a manual process, allows the mounting state to be inspected at the same time as the inspection process for other electronic parts, and facilitates the use of a conventional inexpensive inspection needle. The purpose is to provide a connector that can be tested for mounting confirmation of the connector.

[0011]

In order to achieve the above object, the present invention provides a connector pin having a foot connected to a conductive pattern on a mounting board and a socket provided on the opposite side of the foot, and one or A connector body holding a plurality of the connector pins, and a hole for continuity inspection reaching the connector pins is provided in the connector body.

Preferably, the continuity inspection hole has a tapered shape.

[0013]

According to the present invention, with the above-described structure, the mounting confirmation test of the connector can be performed by conducting the continuity inspection between the continuity inspection hole and the conductive pattern to which the foot of the connector pin is connected. . Further, since the tip of the continuity inspection needle is automatically guided to each connector pin by the taper-shaped continuity inspection hole, it is possible to use the continuity inspection needle that is inexpensive and does not require high accuracy.

[0014]

Embodiments of the present invention will be described with reference to FIGS. In FIG. 1, 11 is a foot 11a connected to the conductive pattern on the mounting board and the foot 1
Socket 11 provided on the opposite side of 1a (not shown)
A connector pin provided with b, 12 is a resin-made connector main body for holding the connector pin 11, and 13 is a tapered conduction inspection hole provided in the connector main body 12 and is opened to reach the connector pin 11. .

A method of the connector mounting confirmation test in the above configuration will be described with reference to FIG.

The foot 11a of the connector pin 11 is mounted on the mounting board 1
After connecting to the conductive pattern 15 on the connector 4 by soldering, one of the test needles 16 is brought into contact with the connector pin 11 and the other of the test needle 16 is brought into contact with the conductive pattern 15 through the conductive test hole 13 of the connector main body, The resistance value between the pin 11 and the conductive pattern 15 is measured by the function tester 17
Then, it is confirmed whether or not the connection between the connector pin 11 and the conductive pattern 15 is made without any problem.

As described above, according to this embodiment, the connector body 12 is provided with the continuity inspection hole 13 so that the inspection needle 16 and the connector pin 11 are brought into contact with each other. The work of inserting the test board into the connector for confirming the mounting of the connector can be reduced, and as a result, the mounting can be confirmed at the same time as the function check of other electronic components on the mounting board 14, and the continuity inspection hole of the connector body 12 can be confirmed. By making 13 a taper shape, it has a role of positioning the inspection needle 16, and the tip of the inspection needle 16 is automatically guided to each connector pin, so that high positioning accuracy is not required. Inexpensive test needles can be used.

As another embodiment as shown in FIG. 3,
A structure in which the holes 13 for continuity inspection are provided in a zigzag shape may be used. In this case, the connector pin 11 protruding from the connector body 12
This is effective for a connector having a narrow pitch of the legs 11a.

In these embodiments, the plane shape of the conduction inspection hole has been described as a circle, but other shapes may be used.

[0020]

As is apparent from the above description, according to the present invention, the mounting confirmation test of the connector can be performed without inserting the test board into the socket of the connector pin.
Not only the step of inserting the test board by a person can be omitted, but also the socket of the connector pin is not damaged by the insertion and removal of the test board. Then, the connector mounting state can be tested at the same time as the generally performed inspection process by the function tester of other electronic components.

Further, by arranging the holes for the continuity inspection in a zigzag pattern or by forming the taper shape, the connector mounting confirmation test can be performed with an inexpensive inspection needle which does not require high positioning accuracy. .
