Background of the devise

The electric wiring inspection jig is used to finally inspect the defective state such as the connection state of the housing terminal pin connected to the inspector and the short circuit state of the wiring connected to the housing. The electric wiring inspection jig has various forms.

First, it can be divided into manual type and air type, and manual type can also be lever type, socket type, touch type, and fuse relay box. It has various forms. However, such manual types have a disadvantage in that the process time is long because they can be buried only by manipulating all the housings one by one. In addition, in terms of quality, there is a risk of damage to the test pin or the terminal of the housing coupled to the test pin due to excessive detachment operation force. In addition, since the shape is complicated, the wire housing may be caught by the lever, thereby causing defective elements such as disconnection and terminal detachment.

On the contrary, since the air type is operated by an air cylinder, the housing is detached at the same time by simply pressing a switch, so the process time is significantly smaller than the manual type, and the work efficiency is also good and the external shape is simple. In addition, since the same force is applied by the air cylinder, there is less damage to the test pin or the housing. In addition, since the shape is simple, there is no jamming of the wire or the housing, so that defective elements such as disconnection and terminal detachment are excluded.

Therefore, the present inventors select the air type so that the housing can be mounted and detached effectively and easily, pushing the pushing block when the housing is mounted, and the knocking guide fixed by the pushing block is lifted up and attached to the knocking guide. The housing is fixed by means of one-touch mounting of the housing and automatically detaching the housing by air injection, as well as eliminating damage to the test pins and terminals of the housing corresponding to the test pins that may occur during mounting and detachment. It further comprises a pin protective surface and a spring for the purpose. The pin protection surface not only prevents bending of the test pin, which may occur due to external impact before, during, or after the test, but also protects the terminal of the housing coupled with the test pin by providing the pin protection surface. . Therefore, when the housing is inserted into the upper body of the test jig by the spring, a part of the upper body is pushed back, and thus the test pin protrudes between the holes formed in the pin protection surface, thereby contacting the terminal of the housing.

An object of the present invention is to provide a one-touch push-type electrical wiring inspection jig that can be easily mounted in a one-touch manner when the housing is mounted.

Another object of the present invention is to provide a one-touch push-type electric wiring inspection jig to prevent damage (terminal, and tester pin) of components that can be caused by excessive detachment operation by mounting in a one-touch manner when mounting the housing.
