It's about the jig.

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. Such electric wiring inspection jig has been developed in various functions and 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 detached 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, and defective elements such as disconnection and terminal detachment may occur.

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.

However, even after being mounted, the test pin and the housing are not contacted, and thus the terminal of the housing and the test pin are contacted by the advancement of the test pin by the injection of air, thereby preventing damage to the test pin and the terminal of the housing. In addition, a pin protection surface is provided to prevent damage to the test pin and the housing terminal, which may occur before, during and after the test. In addition, as the housing is automatically detached by air injection, the entire process of inspection is to devise an air-push type electric wiring inspection jig which is automatically performed by air injection.
