Technical Field

[0001] The utility model relates to the technical field of cable connectors, in particular to a safe and fastened coaxial cable connector. Background Art

[0002] The coaxial cable connector is one of the essential components in the RF signal transmission line. Its main function is to connect various coaxial cables and ensure that the signal can be effectively transmitted from one device to another by providing a stable and reliable connection.

[0003] At present, the coaxial cable connector is composed of a connector and a connector. The installation operation of the coaxial cable connector is as follows: first, the outer sheath and the inner insulation layer of the cable end are stripped to expose the center conductor, and then the connector is inserted into the cable port and then screwed into the connector to complete the installation. However, after the connector is installed, the excess conductor needs to be cut off to retain the appropriate length, but the cutting length is difficult to control. If the cable conductor is cut too short, poor contact is likely to occur between the coaxial cables during subsequent use.

[0004] Therefore, there is an urgent need to provide a safe and fastened coaxial cable connector that can control the cable cutting length. Utility Model Content

[0005] In order to overcome the shortcomings of the current connector installation in which it is difficult to control the cutting length when cutting the conductor, which easily causes the cable conductor to be cut too short, resulting in poor contact between the coaxial cables during subsequent use, the utility model provides a safe and fastened coaxial cable connector with controllable cable cutting length.

[0007] Furthermore, a connecting ring is fixedly connected to the bottom end of the connecting seat, a clamping sleeve for clamping a cable is fixedly connected to the bottom end of the connecting ring, and a limiting ring is arranged outside the connecting ring.

[0008] Furthermore, the inner ring of the connecting collar and the inner ring of the limiting collar are both provided with thread grooves, and the ferrule and the limiting collar are connected and fixed via the thread grooves.

[0009] Furthermore, the ferrule is made of flexible plastic.

[0010] Furthermore, the ferrule is conical, and the inner wall of the lower end of the limiting ring fits with the outer surface of the ferrule.

[0011] Furthermore, a plurality of support seats are embedded in the outer surface of the joint, a locking ball is arranged in the support seat, and the locking ball is connected to the support seat through a second elastic member.

[0012] Furthermore, the inner surface of the connecting seat is provided with a locking hole matching the locking ball.

[0013] Furthermore, the top of the joint is covered with a protective cover.

[0014] Furthermore, a plurality of anti-slip pads are arranged on the inner surface of the ferrule.

[0015] Furthermore, a latch is provided on the limiting collar.

[0016] Compared with the prior art, the utility model has the following technical effects: 1. The conductor cutting length is positioned by the distance plate, and the conductor cutting length is controlled by cutting off the excess conductor above the distance plate, so as to ensure that the retained conductor length is appropriate.

[0017] 2. The limiting collar and the connecting collar are threadedly matched to clamp the cable with the ferrule to install the connecting seat, which can achieve a firm connection and facilitate the subsequent disassembly and assembly of the connecting seat. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0026] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the utility model. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the utility model.

[0027] Example 1

[0028] See also Figure 1-Figure 3 A safe and fastening coaxial cable connector comprises a connecting seat 1 and a connector 2, wherein the connecting seat 1 and the connector 2 are connected by a snap-fitting manner, and the top of the connector 2 is covered with a protective cover 13. When the device is stored, the connector 2 is sealed with the protective cover 13 to prevent foreign matter from entering. A mounting plate 3 is arranged outside the connecting seat 1, and a connecting frame 4 is slidingly arranged on the mounting plate 3. Four distance plates 5 evenly distributed along the circumferential direction are fixedly connected to the top of the connecting frame 4, and the distance plates 5 are used to locate the cutting length of the cable conductor. A first elastic member 6 is sleeved on the connecting frame 4, and the two ends of the first elastic member 6 are respectively connected to the connecting frame 4 and the mounting plate 3.

[0029] First, insert the connector 1 into the end of the coaxial cable, and then use the distance plate 5 to locate the conductor cutting length. The staff cuts off the excess conductor above the distance plate 5 to control the conductor cutting length and ensure the appropriate length of the conductor. Finally, insert the connector 2 into the connector 1, and at the same time, squeeze the distance plate 5 downward to retract it until the connector 2 and the connector 1 are docked.

[0030] Example 2

[0031] Based on Example 1, please refer to Figure 4 and Figure 5The bottom end of the connecting seat 1 is fixedly connected with a connecting ring 7, and the bottom end of the connecting ring 7 is fixedly connected with a clamping sleeve 8 for clamping the cable. A limiting ring 9 is arranged outside the connecting ring 7. The inner ring of the connecting ring 7 and the inner ring of the limiting ring 9 are both provided with thread grooves, and the clamping sleeve 8 and the limiting ring 9 are connected and fixed through the thread grooves. The clamping sleeve 8 is made of flexible plastic, which is convenient for contracting and clamping the cable, and the clamping sleeve 8 is conical, and the inner wall of the lower end of the limiting ring 9 is in contact with the outer surface of the clamping sleeve 8. By rotating the connecting ring 7, the ferrule 8 is moved down along the limiting ring 9, and then the inner wall shape of the limiting ring 9 is used to squeeze the ferrule 8 to contract, so as to clamp the cable. The inner surface of the ferrule 8 is provided with a plurality of anti-skid pads 14. When the ferrule 8 clamps the cable, the anti-skid pads 14 increase the friction force and play an anti-skid role. The limiting ring 9 is provided with a pin 15. After the connecting seat 1 is installed, the pin 15 is inserted into the limiting ring 9 to clamp the connecting ring 7 and fix it to prevent the connecting ring 7 from rotating during use.

[0032] When the device is installed on the coaxial cable, the limiting ring 9 is first put on the cable end, and then the connecting ring 7 is put into the limiting ring 9, and then the connecting ring 7 is rotated. Under the action of the thread, the connecting ring 7 drives the clamping sleeve 8 to move downward, and at the same time, the clamping sleeve 8 is squeezed by the inner wall of the limiting ring 9 to contract and clamp the cable. In this way, the installation of the connecting seat 1 is completed, and it is convenient for subsequent disassembly and assembly while achieving a firm connection.

[0033] See also Figure 6 and Figure 7 The outer surface of the joint 2 is embedded with a plurality of support seats 10 evenly distributed along a ring, and a card ball 11 is arranged inside the support seat 10. The card ball 11 is connected to the support seat 10 through a second elastic member 12. By using the second elastic member 12, the card ball 11 can realize telescopic action. The inner surface of the connecting seat 1 is provided with a card hole matching the card ball 11. The joint 2 can be fixed by snapping the card ball 11 into the card hole to avoid the loose connection between the connecting seat 1 and the joint 2 during use.
