Description

Technical Field

[0001] The invention relates to the technical field of cable joints, and in particular to a novel cable joint. Background Art

[0002] Cable joints are also called cable heads. After the cable is laid, in order to make it a continuous line, each section of the line must be connected as a whole, and these connection points are called cable joints. The cable joints in the middle of the cable line are called intermediate joints, and the cable joints at both ends of the line are called terminal heads. Cable joints are used to lock and fix the incoming and outgoing lines, and play a role in waterproofing, dustproofing and vibration prevention.

[0003] If the heat dissipation effect of the cable joint is poor, it will expand when heated, which may affect the use of the cable joint at the least and may even cause an explosion at the worst. Therefore, a new type of cable joint is needed to provide heat dissipation effect.

[0004] The clamping claw mentioned in the present invention has the same structure as the clamping claw mentioned in the patent "A clamping claw and a waterproof fixing head using the clamping claw", and the application number is "CN201020541773.8". Summary of the invention

[0005] The purpose of the invention is to provide a novel cable connector with autonomous heat dissipation function.

[0006] In order to achieve the above object, the technical solution adopted by the present invention is:

[0007] A novel cable connector comprises an anti-bending urgent nut, a clamping jaw part, a main body and a main nut which are arranged in sequence from left to right. The outer wall of the main body is provided with a thread. The clamping jaw part is arranged on the left side of the main body and is fixedly connected thereto. One side of the main body provided with the clamping jaw part is screwed into the right side of the anti-bending urgent nut and is screwed and matched therewith. The main nut is fixedly arranged on the outer wall of the main body. The anti-bending urgent nut comprises a nut body and a first spring. The first spring is fixedly arranged on the left side of the nut body. An inclined surface is arranged on the inner wall of the nut body towards the side of the clamping jaw part. The inclined surface is inclined towards the side facing away from the clamping jaw part. A plurality of placement grooves are arranged along the circumferential direction of the nut body on the inclined surface. The clamping jaw part comprises a main body, a rubber ring, and more than two small claws arranged on the main body. The small claws are arranged on the main body in an annular display. The rubber ring is fixedly arranged on the inner wall of the small claw and is fixedly connected thereto. The butt joint surface between adjacent small claws is an inclined surface. The spacing distance between any two adjacent placement grooves is less than the spacing distance between any two small claws. The arc length of the placement groove is greater than the arc length of the interval between two adjacent small claws.

[0008] The present invention is further configured such that the outer wall of the nut body is configured in the shape of a regular hexagon, a secondary nut is provided on the right side of the main nut, the secondary nut is screwed together with the main body, the diameter of the circumscribed circle of the secondary nut is larger than the diameter of the circumscribed circle of the main nut, the secondary nut is in the shape of a regular hexagon, each of the six corners of the nut body is provided with a first plug-in hole, the first plug-in hole passes through the nut body, each of the six corners of the secondary nut is provided with a second plug-in hole corresponding to the first plug-in hole, the second plug-in hole passes through the secondary nut, each of the second plug-in holes is provided with a plug-in column plug-matched therewith, the plug-in column passes through the second plug-in hole and is plug-inly arranged in the first plug-in hole, the plug-in column is composed of two fixing columns and a second spring, the fixing column is arranged at both ends of the second spring and fixedly connected thereto, the fixing columns are respectively located in the first plug-in hole and the second plug-in hole, the second spring is located between the first plug-in hole and the second plug-in hole, and the surface of the fixing column is roughened.

[0009] The present invention is further configured such that a limiting ring is provided on each side of the fixing column facing away from the second spring and fixedly connected thereto, wherein one limiting ring is abutted against the side of the nut body facing away from the main body, and the other limiting ring is abutted against the side of the secondary nut facing away from the nut body.

[0010] Beneficial effects of the present invention:

[0011] (1) The connection relationship between the clamping jaw portion and the nut body and the structural design of the present invention can cause the air in the receiving groove to expand after being heated, exerting a certain pressure on the gap between the small claws on the clamping jaw portion, so that the main body is partially screwed out of the nut body, so that a certain gap exists between the nut body and the clamping jaw portion to achieve the heat dissipation effect.

[0012] (2) The structure of the outer wall of the nut body, the secondary nut, the first plug-in hole, the second plug-in hole, and the plug-in column (the plug-in column is composed of two fixed columns and a second spring) of the present invention are designed so that after the heat dissipation is completed, due to the elasticity of the second spring, the main body continues to be screwed into the nut body and returns to its original state.

[0013] (3) The design of the limiting ring of the present invention can prevent the fixing column from running out of the first plug-in hole and the second plug-in hole. BRIEF DESCRIPTION OF THE DRAWINGS

The clamping jaw portion 7 includes a body 21, a rubber ring 23, and more than two small claws 22 arranged on the body 21. The small claws 22 are arranged in a ring-shaped manner on the body 21. The rubber ring 23 is fixedly arranged on the inner wall of the small claws 22 and fixedly connected thereto. The butt joint surface between adjacent small claws 22 is an inclined surface. The spacing distance between any two adjacent placement grooves 3 is less than the spacing distance between any two small claws 22. The arc length of the placement groove 3 is greater than the arc length of the spacing between two adjacent small claws 22.

[0023] The outer wall of the nut body 2 is arranged in the shape of a regular hexagon, a secondary nut 9 is arranged on the right side of the main nut 6, the secondary nut 9 is screwed together with the main body 5, the diameter of the circumscribed circle of the secondary nut 9 is larger than the diameter of the circumscribed circle of the main nut 6, the secondary nut 9 is in the shape of a regular hexagon, and a first plug hole 11 is arranged at each of the six corners of the nut body 2, the first plug hole 11 passes through the nut body 2, and a second plug hole 10 is arranged corresponding to the first plug hole 11 on each of the six corners of the secondary nut 9, and the second plug hole 10 is set through the secondary nut 9, and the second plug-in hole 10 is respectively provided with a plug-in column that is plugged and matched therewith.
