Description

Technical Field

[0001] The utility model relates to a coaxial connector, in particular to a novel large cable radio frequency coaxial connector. Background Art

[0002] RF coaxial connectors are usually considered to be a component installed on cables or instruments. As a component for electrical connection or separation of transmission lines, it is a mechatronics product. Simply put, it mainly plays a bridging role. In existing RF coaxial connectors, the connection between the front shell and the cable clamp is the cable clamping part. The existing structure can only clamp half of the wave peak copper skin, and the connection is unstable and prone to falling off.

[0003] In the prior art, the front housing and the rear housing are usually connected by threads. However, when the torque is too large when tightening the rear housing, the copper skin of the cable is easily compressed and cracked or even broken, resulting in data shifting and affecting performance.

[0004] Secondly, the cable clamp in the existing RF coaxial connector is only placed in the rear housing without being connected, so the cable clamp is easy to fall off from the rear housing during installation, affecting the efficiency of installation and assembly. To this end, a new large cable RF coaxial connector is proposed. Utility Model Content

[0005] The utility model aims to solve the above problems and proposes a novel large cable radio frequency coaxial connector.

[0006] In order to achieve the above-mentioned purpose, the utility model provides the following technical solution: a novel large-cable radio frequency coaxial connector, comprising a front shell, a rear shell installed on the front shell, an insulator installed on the front shell, a pin installed on the front shell, and a rivet tube installed on the pin; it is characterized in that it also includes a cable clamp movably installed on the rear shell and a compensation step arranged on the front shell; the front end of the cable clamp is provided with a plurality of slots, so that the front end of the cable clamp forms a plurality of elastic claws.

[0007] Further preferably, a limit platform is provided on the rear housing, and a slide groove adapted to the limit platform is provided on the cable clamp, and the cable clamp is installed on the rear housing through the coordinated movement of the limit platform and the slide groove.

[0008] Further preferably, the front shell is provided with a sealing groove 1, in which a sealing sleeve is installed, and the rear shell is provided with a sealing groove 2, in which a sealing ring is installed.

[0009] Further preferably, the front shell is also provided with a socket.

[0010] Further preferably, a limiting step is also provided on the outer side of the rear shell.

[0011] The beneficial effects of the utility model are as follows: by arranging a compensation step on the front shell, the copper sheet of the cable is pressed down and folded inward by the compensation step while the front shell and the rear shell are pressed tightly, and then the folded copper sheet is pressed on the clamping surface of the front shell and the cable clamp, thereby increasing the thickness of the clamping surface, so that the contact is more stable after pressing;

[0012] By arranging a limit platform on the rear shell and arranging a slide groove adapted to the limit platform on the cable clamp, the cable clamp is squeezed and retracted by the limit platform on the elastic clamping claw during installation until the limit platform is stuck in the slide groove, and the cable clamp is movably installed on the rear shell, and is not easy to fall off after installation.

[0016] Hereinafter, we will further explain the novel large cable radio frequency coaxial connector described in the utility model in conjunction with the accompanying drawings.

[0017] It should be noted that all directional indications such as up, down, left, right, front, back... in the embodiments of the utility model are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture as shown in the accompanying drawings. If the specific posture changes, the directional indication will also change accordingly.

[0018] In the present invention, unless otherwise clearly specified and limited, the terms "connection", "fixation" and the like shall be used in a broad sense. For example, "fixation" may be a fixed connection, a detachable connection, or an integral connection; it may be a mechanical connection or an electrical connection; it may be a direct connection or an indirect connection through an intermediate medium; it may be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0019] See also Figure 1-2As shown in the figure, a novel large cable radio frequency coaxial connector comprises a front shell 1, a rear shell 2 installed on the front shell 1 by interference fit, an insulator 3 installed on the front shell 1, a pin 4 installed on the front shell 1 and a rivet tube 5 installed on the pin 4; it is characterized in that it also comprises a cable clamp 6 movably installed on the rear shell 2 and a compensation step 7 arranged on the front shell 1; the front end of the cable clamp 6 is provided with a plurality of slots 8, so that a plurality of elastic clamping claws 9 are formed at the front end of the cable clamp 6;

[0020] By arranging a compensation step 7 on the front shell 1, the copper skin of the cable is pressed down and folded inward by the compensation step 7 while the front shell 1 and the rear shell 2 are pressed tightly, and then the folded copper skin is pressed against the clamping surface of the front shell 1 and the cable clamp 6, thereby increasing the thickness of the clamping surface and making the contact more stable after pressing.
