Abstract

The utility model relates to the technical field of connecting fittings, in particular to an insulating joint, which comprises an insulating joint, wherein the insulating joint is an insulating joint structure, and the front end of the insulating joint structure is fixedly connected with a connector; and the insulating structure is arranged on the inner side of the connector. The utility model overcomes prior art's is not enough, through setting up insulation system, the setting is in the inboard of insulating joint, insulation system includes that synthetic rubber layer and polyamide plastic layer constitute, synthetic rubber layer constitutes for the synthetic rubber material, it is difficult for receiving the environmental factor influence to have good heat resistance and corrosion protection nature, the polyamide plastic layer constitutes for the polyamide material, good wearability has, self-lubricity and cable surface friction coefficient are little, synthetic rubber layer and polyamide plastic layer all have good insulating nature, both cooperate the use to improve the insulating nature that this connects, avoid its junction cable to appear the cable joint that breaks when guaranteeing metal joint's life cycle to become the possibility that the conductor influences normal use.

Description

Insulating joint

Technical Field

The utility model relates to a connect accessory technical field, specifically be an insulating joint.

Background

The cable connector is also called a cable head. After the cable is laid, the sections of the cable must be connected together in order to form a continuous line, and these connections are called cable connectors. The cable joints at the middle of the cable run are called intermediate joints and the cable joints at the two ends of the run are called termination joints. The cable joint is used for locking and fixing incoming and outgoing lines, plays a role in water resistance, dust resistance and vibration resistance, is divided into an outdoor type and an indoor type according to installation places, and mainly has the main functions of enabling a line to be smooth, enabling the cable to keep sealed, ensuring the insulation grade at the cable joint and enabling the cable joint to operate safely and reliably. If the sealing is poor, not only oil leakage causes oil-impregnated paper to dry up, but also moisture invades into the cable, so that the insulating property of the cable is reduced.

Referring to the better market star-rui brand number: XR-MA thermal contraction type cable joint, its joint one end is connected with prevents bending, ductility, strong flexible pipe of application environment, but most cable joints make its junction cable for metal material and appear the cable joint that breaks and become the conductor, cause the electric leakage influence normal use, the cable joint that plastic material made has good insulating nature but exposes outside for a long time and easily receives environmental factor influence its life weak point.

SUMMERY OF THE UTILITY MODEL

Not enough to prior art, the utility model provides an insulating joint aims at solving prior art, and the poor problem of metal cable joint insulating effect.

In order to solve the technical problem, the utility model provides a following technical scheme:

an insulated joint, comprising: the insulation joint is an insulation joint structure, and the front end of the insulation joint is fixedly connected with a threaded joint; the connector is arranged on the inner side of the threaded connector; and the insulation structure is arranged on the inner side of the connector.

Preferably, the length of the insulating structure is the total length of the joint.

Preferably, the outer side of the insulation structure and the inner side of the connector are in welded connection.

The embodiment of the utility model provides an insulating joint possesses following beneficial effect: this insulating joint is through setting up insulation system, sets up in insulating joint's inboard, and insulation system includes that synthetic rubber layer and polyamide plastic layer constitute, and synthetic rubber layer constitutes for the synthetic rubber material, and the polyamide plastic layer constitutes for the polyamide material, and synthetic rubber layer and polyamide plastic layer all have good insulating nature, avoids its junction cable to appear the cable joint that breaks to become the conductor influence normal use possibility when guaranteeing metal joint's life cycle.

1. Through setting up insulation system, the setting is in the inboard that insulating joint, insulation system includes that rubber composition layer and polyamide plastic layer constitute, rubber composition layer is the rubber composition material composition, it is difficult for receiving the environmental factor influence to have good heat resistance and corrosion protection nature, the polyamide plastic layer is the polyamide material composition, good wearability has, self-lubricity and cable surface coefficient of friction are little, rubber composition layer and polyamide plastic layer all have good insulating nature, both cooperate the insulating nature that improves this joint, avoid its junction cable to appear the cable joint that breaks to become the conductor and influence the possibility of normal use when guaranteeing metal joint's life cycle length.

Drawings

The accompanying drawings are included to provide a further understanding of the invention, and are incorporated in and constitute a part of this specification, illustrate embodiments of the invention, and together with the description serve to explain the invention and not to limit the invention. In the drawings:

fig. 1 is a schematic view of the overall cross-sectional structure of the present invention.

In the figure: 1. an insulated joint; 2. a connector; 3. an insulating structure; 4. provided is a threaded joint.

Detailed Description

The preferred embodiments of the present invention will be described in conjunction with the accompanying drawings, and it will be understood that they are presented herein only to illustrate and explain the present invention, and not to limit the present invention.

Example (b): as shown in fig. 1, an insulated joint, comprising: the insulation joint 1 is an insulation joint structure, and the front end of the insulation joint is fixedly connected with a threaded joint 4; connector 2, it sets up in screwed joint 4's inboard, screwed joint 4 is used for being connected with other ports through the screw thread, the inboard of connector 2 is provided with insulation system 3, insulation system 3's length is the total length of joint, install the cable through insulation system 3's inboard again during the installation, insulation system 3 includes that synthetic rubber layer and polyamide plastic layer constitute, synthetic rubber layer is the synthetic rubber material constitution, it is difficult for receiving environmental factor to influence the damage to have good heat resistance and corrosion resistance, prolong its life cycle when improving joint insulating nature, the polyamide plastic layer is the polyamide material constitution, has good wearability, self-lubricity and cable surface coefficient of friction are little, further reduce the wearing and tearing of joint to the cable surface when improving the joint, avoid its junction cable to appear the cable joint that breaks and become the conductor influence normal use possibility when guaranteeing metal joint's life cycle.

The working principle is as follows: this kind of insulated joint is through setting up insulation system 3, insulation system 3's length is the joint overall length, install the inboard that the cable passes through insulation system during installation again, insulation system 3 includes synthetic rubber layer and polyamide plastic layer, synthetic rubber layer is the synthetic rubber material composition, it is difficult for receiving environmental factor influence to damage to have good heat resistance and corrosion resistance, prolong its life cycle when improving joint insulation nature, the polyamide plastic layer is the polyamide material composition, good wearability has, self-lubricity and cable surface friction coefficient are little, the insulating nature that further improves the joint reduces the wearing and tearing that connect to the cable surface simultaneously.
