Problems solved by technology

[0002] In the current prior art, in the electronics and communication industries, the RF coaxial cable assembly usually has an integrated structure, and the cable and connector are fixed by welding and crimping, and the insulator is fixed by barbs and spot glue. , the cable core wire and pins are welded, but these installation methods have defects: once there is a problem with the production and assembly performance, they cannot be disassembled and reused, causing the entire joint to be scrapped, which will cause a lot of cost waste

Embodiment 1

[0033] like figure 1 As shown, a detachable cable assembly includes a casing, an insulator 1 and a cable installed in the casing, and the casing includes a rear casing 2, a positioning casing 3 and a locking casing that are detachably connected in sequence from back to front 4. The tail housing 2 is slidably connected with the positioning housing 3 , and the locking housing 4 is connected with the positioning housing 3 through internal threads and external threads that cooperate with each other.

[0034] The cable includes a cable body 27 and pins 28 that are connected to each other, and the insulator 1 presses the pins 28 into the tail housing 2, that is, the insulator 1 is tightly fitted with the pins 28 and the tail housing 2, and the insulator 1 is in a tight fit. It is fixed with the pin 28 by the barb snap connection, and the two can move together.

[0035] The front end of the pin 28 is provided with a petal-shaped clamping claw 29, and the tail of the cable body 27 i...

Embodiment 2

[0050] like figure 2 As shown, this embodiment adds a limiting structure to the positioning housing 3 on the basis of the first embodiment, so that the positioning housing 3 can be assembled accurately. This embodiment also includes an elastic clamp 15 and a limit ring 16 , which are located in the space enclosed by the annular groove 14 and the cylindrical body 9 . In the free state, the elastic member 10, that is, the front end of the compression spring, is pressed by an elastic clamp 15 to increase the friction force between the compression spring and the cylinder 9; the elastic clamp 15 is fixedly connected to the limit ring 16 outside, elastic The clamp 15 also exerts an outward pressure on the limit ring 16 , so that the limit ring 16 presses against the annular groove 14 outward. The compression spring and the elastic clamp 15 keep the limit ring 16 in a relatively fixed state, and the limit ring 16 is in close contact with the front side wall of the annular groove 14...

Embodiment 3

[0055] like Figure 3 to Figure 6 As shown, this embodiment adds another limiting structure to the positioning housing 3 on the basis of the first embodiment. A limit assembly 17 for limiting the positioning shell 3 is provided on the outer wall of the tail housing 2 near the rear end of the positioning shell 3 . The limit assembly 17 includes a lock ring 18 and a rotation pin 19 . The tail housing 2 is formed with a ring groove and a pin groove that communicates with the ring groove. The rotating pin 19 is located in the pin groove and is hinged to the tail housing. The lock ring 18 is embedded in the ring groove and is locked in the ball 8 When the insulator 1 is tightened, the rotating pin 19 is pressed against the front end surface of the locking ring 18 to be in a vertical state, thereby preventing the rear end surface of the positioning housing 3 from moving backwards. The top wall of the lock ring 18 is provided with a groove body 1 20, which is used to accommodate the...

Abstract

A detachable cable assembly provided by the present invention comprises a housing and an insulator and a cable installed in the housing, the housing comprises a positioning housing and a locking housing, the rear end face of the insulator is positioned by a first step in a tail housing, the insulator and the tail housing are respectively provided with a bead groove and a bead hole, the inner wall of the positioning housing is provided with a first boss, and the inner wall of the locking housing is provided with a second boss. The front side wall of the first boss is a first slope inclining forwards, a gap between the inner wall of the positioning shell and the outer wall of the tail shell is a movable gap, and the movable gap is smaller than the diameter of the ball. When the positioning shell moves backwards, the first boss loosens the ball, and when forward pulling force is applied to the insulator, the ball is separated from the ball groove and extends into the movable gap from the ball hole, so that the insulator is loosened. When the positioning shell moves forwards, the balls are pressed into the ball holes and the ball grooves under the guidance of the first slope surfaces, and then the balls are continuously pressed by the first bosses, so that the insulator is in a locked state. The device can be flexibly detached and separated, maintenance and inspection are facilitated, and material scrapping is reduced.

Description

technical field [0001] The invention belongs to the technical field of communication devices, and in particular relates to a detachable cable assembly. Background technique [0002] In the current state of the art, in the electronics and communication industries, RF coaxial cable assemblies are usually of an integral structure with an integrated housing, and the cables and joints are fixed by welding and crimping, and the insulators are fixed by barbs and glue-pouring. , The cable core wire and the pin are welded, but these installation methods have defects: once the production and assembly performance is problematic, they cannot be disassembled and reused, resulting in the entire joint will be scrapped, which will cause a lot of cost waste. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide a detachable cable assembly to solve the above technical problems. [0004] The invention provides the following technical solutions: [0005] A det...
