Preferably, the fixed end and the connecting end are arranged on two sides of the annular boss, the fixed end, the annular boss and the connecting end are connected to form an integral structure, the outer side of the fixed end is provided with the first external thread, and the outer side of the connecting end is provided with the second external thread.

According to the arrangement, the threaded connection of the wire insulation skin and different types of lamps and electric appliances is realized through the action of the first external thread, so that the connection of the wire insulation skin is more convenient; and meanwhile, limiting is performed through the action of the annular boss.

Preferably, a through hole is formed in the connector, and one end of the sheath is inserted into the through hole.

This arrangement achieves connection of the joint with the sheath.

Preferably, an inner cavity is arranged on the inner side of the locking cover, and an inner thread matched with the first outer thread is arranged in the inner cavity.

The quick connection between the locking cover and the connector is realized through the functions of the internal thread and the external thread, and meanwhile, the quick connection between the locking cover and a lamp, an electric appliance and the like is also realized.

Preferably, one end of the locking cover adopts a spherical structure.

This setting for the difficult hydrops in top of locking lid is convenient for flow out fast of liquid, plays certain waterproof effect.

Preferably, the fixing end is provided with a second sealing ring, and one side of the connecting end is provided with a first sealing ring.

This setting has realized locking lid, joint and sheath junction's two-layer seal, has further improved the waterproof performance in the wire rod insulating skin outside, has further increased the security when using.

The beneficial effects of the utility model are as follows: the structure is exquisite, and waterproof nature is good, can be directly used for lamps and lanterns, electrical apparatus on for liquid etc. can not get into the inside of lamps and lanterns, electrical apparatus etc. along with wire rod insulating skin, be convenient for simultaneously with lamps and lanterns, electrical apparatus between be connected, hang the demand, it has practicality and the universality of use between different grade type lamps and lanterns, the electrical apparatus.
