Anti-bend cable structure

technical field

The utility model relates to a radio frequency cable structure, in particular to an anti-bending cable structure for protecting core wire welding parts.

Background technique

As shown in Figure 1, the main structure of the radio frequency cable 1 generally includes a connector 10 and a core wire 11 made of a copper conductor. The head 10 can be connected with other cables or devices. The manufacturing process is to first fix one end of the core wire 11 to the connector terminal 101 by welding, and then form one or more insulating and shielding layers 12 (rubber sheath) on the core wire 11 .

There are certain hidden dangers in the structure of this radio frequency cable 1: during installation or use, especially when the environment is relatively complicated, in order to adjust the connector 10 to the necessary angle, the cable 1 will inevitably Bending occurs, and the fixed part of the core wire 11 and the terminal 101 is welded and fixed, which lacks toughness. Once repeatedly bent, it may be damaged or even completely broken, resulting in the scrapping of the cable.

Therefore, in order to solve the above problems, it is necessary to provide a cable structure capable of avoiding the bending of the welding part of the core wire.

Utility model content

The purpose of the utility model is to provide a cable structure capable of avoiding the bending of the welding part of the core wire.

In order to achieve the above object, the utility model provides an anti-bending cable structure, the cable includes a connector, a core wire, a core wire sheath, a protective sleeve and a shielding layer, the connector has a terminal, the core One end of the wire is fixed to the terminal, the core wire sheath covers the core wire and exposes the end where the core wire is fixed to the terminal, and the protective sleeve covers the connection between the core wire and the terminal. , the shielding layer is covered on the core wire sheath, the core wire and the protective sheath.

Compared with the prior art, since the anti-bending cable structure of the present invention is covered with the protective sleeve at the fixing point between the terminal and the core wire, the fully formed cable will be Or during use, no matter how the connector adjusts the angle, only the wire of the cable will be bent, and the fixed part between the core wire and the terminal will not be bent due to the protection of the protective sleeve. bent. The protective cover has a simple structure and is easy to assemble, and can effectively protect the welding part of the cable and prolong the service life of the cable.

Preferably, the protective sheath is a protective sheath made of plastic.

Preferably, the cross-sectional size of the terminal is larger than the cross-sectional size of the core wire, the inner diameter of the protective sleeve corresponds to the cross-sectional size of the terminal, and one end of the protective sleeve is tightly sleeved on the on the above terminals.

Specifically, the connector includes an interface, a flange portion, and the terminals, the interface and the terminals are respectively arranged on both sides of the flange portion, and the protective sleeve abuts against the flange portion to set the end face of the terminal.

detailed description

Preferred embodiments of the present utility model are described below in conjunction with the accompanying drawings of the description.

As shown in FIG. 2 to FIG. 4 , the utility model provides an anti-bending cable structure, and the cable 2 includes a connector 21 , a core wire 22 , a core wire sheath 23 , a protective sheath 24 and a shielding layer 25 . Figure 4 shows the cable 2 after processing, while Figure 2 and Figure 3 show the cable 2 when the shielding layer 25 is incomplete, the purpose is to clearly show the cable 2 internal structure.

The connector 21 includes an interface 211 , a flange portion 212 and a terminal 213 , and the interface 211 and the terminal 213 are respectively disposed on two sides of the flange portion 212 . The core wire 22 is made of conductors such as copper commonly used in the field, the core wire sheath 23 is covered on the core wire 22 and exposes one end of the core wire 22, and the core wire 22 exposes the core The end outside the wire sheath 23 is welded and fixed to the terminal 213 . The cross-sectional size of the terminal 213 is larger than the cross-sectional size of the core wire 22 . The protective sleeve 24 is specifically a protective sleeve 24 made of plastic, the inner diameter of the protective sleeve 24 corresponds to the cross-sectional size of the terminal 213 and one end of the protective sleeve 24 is tightly sleeved on the On the terminal 213 , this end of the protective sleeve 24 also abuts against the end face of the flange portion 212 where the terminal 213 is disposed. The other end of the protective cover 24 extends to the part of the core wire 22 exposed outside the core wire sheath 23, so that the part where the core wire 22 and the terminal 213 are welded and fixed is covered on the protective cover. Set within 24. The shielding layer 25 covers the core wire sheath 23 , the core wire 22 and the protective sheath 24 , and the shielding layer 25 is in contact with the end surface of the flange portion 212 where the terminal 213 is disposed. Both the core wire sheath 23 and the shielding layer 25 play the role of shielding and insulation.

When making the cable 2, first pass the protective sheath 24 onto the core wire 22 with the core wire sheath 23, and then weld and fix one end of the core wire 22 to the terminal 213 superior. Then slide the protective sleeve 24 to the end of the core wire 22 so that it is tightly sleeved on the terminal 213 and abuts against the end surface of the flange portion 212 . Finally, the shielding layer 25 is shaped by means of injection molding or the like. Compared with the manufacturing process of the traditional cable, the manufacturing process of the cable 2 of the present invention only adds the step of inserting the protective sheath 24 , and this step is simple and easy to operate.

Compared with the prior art, the utility model, because the protective cover 24 is set on the welding part, the formed cable 2 is installed or used, no matter how the connector 21 adjusts the angle, only the The wires of the cable 2 will be bent, and the welded fixed part of the core wire 22 and the terminal 213 will not be bent due to the protection of the protective cover 24 . The protective cover 24 has a simple structure and is easy to assemble, which can effectively protect the welding part of the cable 2 and prolong the service life of the cable 2 .

What is disclosed above is only a preferred example of the utility model, and its function is to facilitate the understanding and implementation of those skilled in the art. Of course, the scope of rights of the utility model cannot be limited by this, so a patent application is made according to the utility model The equivalent changes made within the scope still belong to the scope covered by the present utility model.
