In order to solve the above technical problem, the purpose of the present invention can be achieved by the following technical solutions:

the utility model provides an inside fire-retardant piece of immersible pump, fire-retardant piece is formed by a plurality of drum interconnect, the axis of drum is located the coplanar, and the one end of drum is provided with the notch that supplies the double-layered line cap to insert the drum inner chamber, notch department week is equipped with the lug of a plurality of fixed double-layered line caps, fire-retardant piece is made by fire-retardant material.

The flame-retardant block is of an integrated structure, a plurality of cylinders are integrally formed in an injection molding mode, the transverse outer walls of the cylinders are wavy, and the number of the cylinders is usually 4.

The wire clamping cap is a nipple type wire clamping cap and comprises a blind head section and a tail part, the blind head section is located in the inner cavity of the cylinder after the wire clamping cap is inserted, and the tail part is located outside the flame-retardant block.

The convex block is an arc-shaped convex block, the axis of the convex block is parallel to the axis of the cylinder, the diameter of a circle surrounded by the convex block is smaller than that of the blind head section, and the diameter of the notch is larger than that of the blind head section.

The number of the above-mentioned projections is usually set to 6-8.

The other end of the cylinder opposite to the notch is opened.

The flame-retardant material is a flame-retardant material commonly used in the field, and only needs to reach the flame-retardant grade required by the flame-retardant test of the submersible pump, and preferably, the flame-retardant material is glass fiber reinforced polypropylene.

Further, the flame-retardant material is PP-GF 30.

Compared with the prior art, the utility model, following beneficial effect has:

1. the utility model discloses insert fire-retardant piece one end with the clamp wire cap, the clamp wire cap is wrapped up inside fire-retardant piece, its clamp wire cap inside metalwork can not with plastic housing direct contact, if the clamp wire cap is on fire then fire-retardant piece can effectively prevent the plastic housing to be on fire, eliminates the potential safety hazard after the clamp wire cap is on fire.

2. The utility model discloses a fire-retardant piece is preferred to use PP-GF30 material, and production is convenient, and low cost compares in adding fire-retardant material in the plastic casing, can save the cost more than 90%.

Detailed Description

The invention will be further described in the following with reference to specific embodiments thereof, with reference to the accompanying drawings, in which figures 1 to 4:

the utility model provides an inside fire-retardant piece of immersible pump, fire-retardant piece 1 is formed by a plurality of drums 11 interconnect, the axis of drum 11 is located the coplanar, and the one end of drum 11 is provided with the notch 13 that supplies double-layered line cap 2 to insert drum inner chamber 12, notch 13 department week is equipped with the lug 14 of a plurality of fixed double-layered line caps 2, fire-retardant piece 1 is made by fire-retardant material.

During installation, the electric wires needing to be connected are peeled off the insulating layers and then twisted together to be inserted into the wire clamping cap 2, the corresponding parts are tightly pressed by the wire pressing tool pliers, and then the wire clamping cap 2 is inserted into the inner cavity 12 of the cylinder through the notch 13.

Referring to fig. 1-2, the flame retardant block 1 is an integral structure, and a plurality of cylinders 11 are integrally injection molded, the transverse outer walls of the cylinders are wavy, and the number of the cylinders 11 is determined according to the number of the wire clamping caps 2 required in the submersible pump, and is usually 4.
