[0021] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0022] Please refer to Figures 1-5 In the embodiments of the utility model, a cable connector for broadcast television coverage comprises an N male joint assembly 2 installed on the outer side of a radio frequency cable 1, the N male joint assembly 2 comprises a connecting sleeve 201, a threaded connector 202, a center needle seat 203, a convex compression ring 204, a first gasket 205, a sealing rubber ring 206, a second gasket 207, a reinforcing connecting piece 208 and a locking nut 209.

[0023] The threaded connector 202 is rotationally connected to the front end of the connecting sleeve 201, the center needle seat 203, the convex compression ring 204, the first gasket 205, the sealing rubber ring 206, the second gasket 207 and the reinforcing connecting piece 208 are sequentially distributed on the inner side of the connecting sleeve 201 in the horizontal direction, and the locking nut 209 is threadedly connected to the rear end of the connecting sleeve 201.

[0024] The radio frequency cable 1 comprises an inner conductor 101, an insulating layer 102, an outer conductor 103 and an outer sheath 104, which are sequentially sleeved and distributed from inside to outside, the front end of the inner conductor 101 is inserted into the inner side of the center needle seat 203 and tightly adheres to the center needle seat 203, the convex compression ring 204 is sleeved on the outer side of the front end of the insulating layer 102, and the first gasket 205, the sealing rubber ring 206, the second gasket 207 and the reinforcing connecting piece 208 are sleeved on the outer side of the outer sheath 104.

[0025] The locking nut 209 presses the sealing rubber ring 206 and the reinforcing connecting piece 208 to make the sealing rubber ring 206 and the reinforcing connecting piece 208 tightly adhere to the outer side of the outer sheath 104, so as to realize the connection and fixation of the N male joint assembly 2 and the radio frequency cable 1.

[0026] The reinforcing connecting piece 208 is composed of two C-shaped rings 2081 and a V-shaped clamping nail 2082, the C-shaped rings 2081 are arranged in two, the V-shaped clamping nail 2082 is fixed between the two C-shaped rings 2081, and when the C-shaped rings 2081 are pressed to move close to each other by the locking nut 209, the V-shaped clamping nail 2082 is further bent and deformed to be inserted into the inside of the outer sheath 104.

[0027] In this embodiment, when the N male joint assembly 1 is connected and assembled with the radio frequency cable 1, the operation method is as follows:

[0028] First, strip the outer sheath 104, outer conductor 103, and insulation layer 102 of the front end of the RF cable 1, so that the front end of the RF cable 1 is in a stepped shape (e.g., Figure 3 );

[0029] Next, the locking nut 209, the reinforcing connector 208, the second washer 207, the sealing ring 206, and the first washer 205 are sequentially fitted from the front end of the RF cable 1 onto the outside of the outer sheath 104. Then, the convex pressure ring 204 is fitted onto the outside of the insulation layer 102, and the thin ring at the front end of the convex pressure ring 204 is inserted between the outer conductor 103 and the insulation layer 102. The front end of the outer conductor 103 is folded outward so that the outer conductor 103 fits against the end face of the thick ring at the rear end of the convex pressure ring 204. Then, the center pin seat 203 is fitted onto the exposed front end of the inner conductor 101 so that the inner conductor 101 fits tightly against the center pin on the center pin seat 203.

[0030] Then, push the locking nut 209 to make the reinforcing connector 208, the second washer 207, the sealing ring 206, and the first washer 205 successively attach and move closer to the convex pressure ring 204. Finally, the folded part of the outer conductor 103 is pressed between the first washer 205 and the convex pressure ring 204.

[0031] Next, the connecting sleeve 201 is fitted onto the outside of the center pin seat 203, the convex pressure ring 204, the first washer 205, the sealing ring 206, the second washer 207, and the reinforcing connector 208, and the locking nut 209 is screwed tightly onto the connecting sleeve 201. During this process, the locking nut 209 will compress the reinforcing connector 208, the second washer 207, the sealing ring 206, the first washer 205, the convex pressure ring 204, and the center pin seat 203 to make them fit tightly together. The sealing ring 206 and the reinforcing connector 208 deform under this compressive force. The deformation of the sealing ring 206 can achieve the seal between the connecting sleeve 201 and the radio frequency cable 1.

[0032] When the reinforcing connector 208 is deformed by force, the two C-rings 2081 approach each other and squeeze the V-shaped clip 2082, causing the V-shaped clip 2082 to bend further. The inner corner of the V-shaped clip 2082 is inserted into the outer sheath 104, thereby realizing the connection and fixation between the N male connector assembly 2 and the radio frequency cable 1, effectively preventing loosening in the later stage.

[0033] Please refer to this carefully. Figures 2-5 Multiple V-shaped fasteners 2082 are arranged in a ring around the center of the C-shaped ring 2081. The outer diameter of the C-shaped ring 2081 matches the inner diameter of the connecting sleeve 201. The inner diameter of the multiple V-shaped fasteners 2082 after bending is smaller than the outer diameter of the outer sheath 104.

[0034] The two end heads of the C-shaped ring 2081 at the gap are shaped symmetrically with annular parts for providing dismounting clamping parts for a dismounting tool.

[0035] In the embodiment, the connection force with the radio frequency cable 1 is further improved by the structure of the plurality of V-shaped clamps 2082, and when the V-shaped clamps 2082 are bent, the C-shaped ring 2081 of the C-shaped structure has an expansion trend under the reverse action, so that the C-shaped ring 2081 and the connecting sleeve 201 are tightly fitted with each other to be relatively fixed, thereby ensuring the stable connection of the connecting sleeve 201 and the radio frequency cable 1.

[0036] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited to this, any person skilled in the art within the technical range disclosed by the present application, according to the technical scheme and the inventive concept of the present application, equivalent replacement or change, should be covered within the protection scope of the present application.
