Abstract

PURPOSE: To provide a multiple pin connector to be connected to a mane multiple pin connector capable of being connected assuredly without short circuit or damage in a mating pin(s) and being durable to repeated attachment and detachment. CONSTITUTION: A plurality of jig pins 16 having an extendable pins 3 deviated by a spring are inserted in a base 1 and fixed, and a pin guide 9 having a separation walls 17 surrounding the pins 13. It is thus possible to guide the advance of mating pin(s) through the separation wall of pin guide at the time of connecting male multiple pin connector and to prevent mating pins from advancing and entering when the mutual positions of both connectors are dislocated or a mating pin(s) is bent so as to enable the connector to be durable to repeated use.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a multi-pin connector which is connected to a male multi-pin connector in which a plurality of pins are arranged.

[0002]

2. Description of the Related Art A conventional multi-pin connector for testing uses a female multi-pin connector 13 of a plug type as opposed to a male multi-pin connector fixed on a substrate 11 as shown in FIG. Alternatively, as shown in FIG. 9, a connector in which a fixed pin 2, a fixed terminal 4, a telescopic pin 3, and a jig pin 6 having a movable terminal 5 are inserted and fixed to a base 1 has been used.

However, the conventional multi-pin connector shown in FIG. 8 has a drawback that it cannot withstand repeated use. Further, in the case of FIG. 9, when the positions of the multi-pin connector and the male connector 12 are displaced, the movable pin 5 becomes the pin 1 as shown in FIG.
It was apt to enter between 3 and to cause a short circuit, or poor contact. Further, when the pin 13 has a bend as shown in FIG. 11, the movable pin 5 has a defect that the bend occurs due to the movable pin 5 sticking into the bend.

[0004]

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a multi-pin connector having a structure which can be reliably connected to a male multi-pin connector and which can endure repeated detachment. is there.

[0005]

In order to solve such a problem, in the present invention, a jig pin having an expanding and contracting pin is inserted into and fixed to a base body, and a separating wall is provided so as to surround the expanding and contracting pin protruding to one side of the base body. The formed pin guide was provided.

[0006]

The multi-pin connector according to the present invention is provided with the pin guide in which the separating wall is formed so as to surround the telescopic pin protruding from the base body, so that when the male multi-pin connector is connected, the separating wall is A short circuit can be prevented by guiding the entry of the pin and preventing the entry of the pin when the positions of both connectors are misaligned or the other pin is bent.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the multi-pin connector of the present invention will be described below with reference to FIGS.

First, the structure and operation of the multi-pin connector of the present invention will be described with reference to FIGS. 1, 2, 3, 4, 5, 6, and 7. FIG. 7 shows an overall view of the signal extraction device for the sample under test, in which sample under test 15 is placed on substrate 14 and sample under test 15
Is arranged so that the signal output of can be taken out from the male type multi-pin connector 12. Further, the multi-pin connector 16 according to the present invention is attached to the tip of the movable arm 17 of the air cylinder 18, and the movable arm 17 moves up and down, whereby the male multi-pin connector 12 and the multi-pin connector 16 are connected. It is configured to be detached.

The multi-pin connector 16 of FIG. 1 has a cylindrical fixed pin 2, an expandable pin 3 which is elastically deformed with respect to the fixed pin 2, and a fixed terminal 4 at one end of the fixed pin 2.
A jig pin 6 having a movable terminal 5 is fixed to the base of the telescopic pin 3 by inserting a plurality of fixing pins 2 into the base 1.
The pin guide 9 is provided with a separating wall 7 so as to surround the telescopic pin 3 protruding to one side. Further, attachment pieces 8a and 8b are provided at both ends of the pin guide 9 for attachment to the base body 1. 2 and 3 are views of the pin guide 9 shown in FIG. 1 as viewed from the bottom. The example of FIG. 2 is an example in which the separating wall 7 forms a circular hole 10, and FIG. This is an example of forming. The operation of the pin guide 9 will be described. For example, in FIG.
When the position of the multi-pin connector 16 and the
3 hits the separating wall 7 and prevents further pins from entering. Further, FIG. 6 shows a state in which the pin 13 is bent, and the pin 13 hits the separation wall 7 to prevent further pins from entering. FIG. 4 shows a state in which the pin 13 is guided by the separation wall 7 in the case where there is no displacement or bending of the pin as described above.

The present invention has been described above with reference to two embodiments, but the present invention is not limited to these embodiments, and the separating wall of the pin guide is not formed between all the pins and one pin is provided. It is also within the scope of the present invention to provide every other pair.

[0011]

As is apparent from the above description, according to the present invention, when the multi-pin connector of the present application is connected to the male multi-pin connector of the connection destination, the separating wall of the pin guide allows the pin to enter. It can also prevent the pin from entering when both connectors are misaligned or the pin is bent. As a result, it is possible to prevent the short circuit and damage of the pin, which is apt to occur in the conventional connector. Further, since it can withstand repeated attachment and detachment, it is possible to provide a multi-pin connector which is particularly suitable for a test apparatus.
