Detailed Description

The present invention will be further described with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.

As shown in fig. 1 to 6: the embodiment discloses rifle that charges of removable terminal, including rifle head 1, rifle casing 2, plug bush shell 4, interchangeable terminal 5 and cardboard subassembly, rifle head 1 is connected in rifle casing 2, and the cardboard subassembly includes crimping

plug bush

7, and 7 one end electricity of crimping plug bush are connected in the cable, but the other end plug is connected in interchangeable terminal 5, and in order to promote the reliability of conducting capacity and connection, the both ends of the interchangeable terminal 5 of this embodiment all are equipped with the reed.

The plug bush shell 4 is equipped with a plurality of plug bush mounting holes with 5 assorted plug bush mounting holes of interchangeable terminal, and interchangeable terminal 5 is installed in the inside of this plug bush mounting hole, and plug bush shell 4 can avoid making interchangeable terminal 5 and extract from the plug bush mounting hole.

The plug bush shell 4 is detachably connected to the gun head 1, a sealing gasket 6 used for sealing and protecting is further arranged between the plug bush shell 4 and the gun head 1, and the plug bush shell 4 can be connected to the gun head 1 through a plurality of screws I3.
