Abstract

The utility model discloses a waterproof power line. The power line comprises a wire and a connector connected to a terminal of the wire. The connector includes a connecting unit, an inner mould seat, an outer mould seat, a thermal shrinkable sleeve and a clasp. The inner mould seat is formed at the rear end of the connecting unit, and the outer mould seat is formed at the rear end of the inner mould seat. The thermal shrinkable sleeve coats the inner mould seat and the outer mould seat. The clasp is mounted on the periphery of the connecting unit. The joints of the connecting unit, the inner mould seat, the outer mould seat and the thermal shrinkable sleeve are provided with waterproof glue layers by which all seams inside are sealed, so that the power line has waterproof properties. The inner end face of the clasp is provided with a waterproof sealing ring, so that when the clasp is in plug connection with an interface of equipment, the sealing ring blocks the seams at the joint part, thereby achieving sealing effects. Thus, the waterproof power line is sealed from both internal and external, and the water seepage problem is effectively prevented.

Preferably, described interior die holder is to adopt the moulding of environmental protection PE material.

Preferably, described interior die holder is to adopt the moulding of PVC material.

Preferably, between described interior die holder and heat-shrinkable T bush, be to be threadedly engaged with structure.

Preferably, described clasp has front end edge to be outward extended with to buckle platform, and is concaved with several fool proof grooves week in this clasp.

Preferably, described connector comprises a circular metal shell, is located at plastic cement main body in metal shell, is located at the several conducting terminals in plastic cement main body.

Preferably, have 7 terminal grooves in described plastic cement main body, the quantity of described conducting terminal has 3PIN, and this 3PIN conducting terminal is plugged in wherein 3 terminal grooves, the empty PIN of all the other 4 terminal grooves; In the outer quilt of this wire, have 3 cores, these 3 cores join and are connected with 3PIN conducting terminal.

The utility model compared with prior art has obvious advantage and beneficial effect, particularly, as shown from the above technical solution, it is mainly because water-proofing treatment is done in the position joining at power line and joint, from joint inside, this connector, interior die holder, outer mould base, heat-shrinkable T bush joint each other all have Waterproof glue line, make so inner seam all seal, effectively waterproof; From joint outside, in the inner face of this clasp, be provided with waterproof grommet, when the interface with equipment is when inserting, sealing circle is blocked the gap being bonded to each other, and realizes sealing.By this, from inside and outside two aspects, all do water-tight measure, effectively avoid seepage problem.

For more clearly setting forth architectural feature of the present utility model and effect, below in conjunction with accompanying drawing and specific embodiment, the utility model is elaborated.

Embodiment

Please refer to shown in Fig. 1 to Fig. 6, the concrete structure that it has demonstrated the preferred embodiment of the utility model, includes wire 10 and the joint 20 that is connected on these wire 10 ends.Wherein:

This joint 20 comprises connector 21, interior die holder 22, outer mould base 23, heat-shrinkable T bush 24 and clasp 25, this interior die holder 22 takes shape in connector 21 rear ends, this outer mould base 23 takes shape in interior die holder 22 rear ends, this heat-shrinkable T bush 24 is coated on outside interior die holder 22 and outer mould base 23, and this clasp 25 is installed on connector 21 peripheries; This connector 21, interior die holder 22, outer mould base 23, heat-shrinkable T bush 24 joint each other all have Waterproof glue line 26, make so inner seam all seal, effectively waterproof.And, in the inner face of this clasp 25, be provided with waterproof grommet 27, when the interface with equipment is when inserting, sealing circle is blocked the gap being bonded to each other, and realizes sealing.

Described interior die holder 22 is to adopt the moulding of environmental protection PE material, and interior die holder 22 is to adopt the moulding of PVC material.Between described interior die holder 22 and heat-shrinkable T bush 24, be to be threadedly engaged with structure.Described clasp 25 has front end edge to be outward extended with to buckle platform 251, and this interior week of clasp 25 is concaved with several fool proof grooves 252.
