Description

Technical Field

[0001] The present invention belongs to the technical field of radio frequency connectors, and specifically relates to a radio frequency connector for a quick-install antenna. 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 belongs to mechatronics products. Simply put, it mainly plays a bridging role.

[0003] Through the joint efforts of experts from various countries, RF coaxial connectors have formed an independent and complete professional system and become an important part of the connector family. They are an indispensable key component of the coaxial transmission system. The RF coaxial connector development technology in the United States, Britain, France and other countries is in a leading position. Its design, production, testing and use technologies have been integrated and perfected. Not only has a complete standard system been formed, but also the raw materials, transmission materials, testing systems, assembly tools, etc. have been standardized and professionalized and mass-produced.

[0004] When connecting a traditional antenna RF connector to a cable, it is necessary to insert the outer shielding layer of the cable into the outer shell and install a compression sleeve on the outer shell for crimping. The connection process of the compression sleeve is not only complicated but also inefficient and costly. The compression sleeve is also very easy to fall off during use. Utility Model Content

[0005] In order to solve the above problems, this paper proposes a quick-installation RF connector for an antenna, the RF connector includes a pin, an insulator, a shell and a nut, one end of the shell is a plug-in end, a cable is plugged into the inner side of the plug-in end, the plug-in end is in the shape of a convex cylinder, the plug-in end is arranged at the center of the end face of the shell, the outer arc surface of the end face of the plug-in end is an inward-retracted necking slope, the inner side of the plug-in end is plug-inly provided with an inner core of the cable, the outer side of the necking slope of the plug-in end is provided with an outer skin of the cable, the outer side of the plug-in end is externally provided with a clamping fixing part, and the clamping fixing part is externally provided with a clamping fixing part. The inner side of one end of the component is connected to the outer side of the plug-in end, and an extrusion cavity is provided between the inner side of the other end of the clamping fixture and the outer side of the plug-in end. A fixing hook is provided on the inner side of the extrusion cavity of the clamping fixture, and an outer skin is provided on the inner side of the extrusion cavity. The outer skin of the cable is extruded on the inner side of the extrusion cavity in a trumpet-like manner through the locking neck slope to separate the inner core, so as to be clamped into the extrusion cavity. The outer skin of the cable is extruded on the inner side of the extrusion cavity, and the protruding and deformed outer skin is fixed by the clamping fixture, so that the cable can be quickly installed and fixed, and the cable can be quickly locked due to the deformation and fixation of the outer skin.

[0006] The outer shell is in the shape of a circular tube shell, one end of the outer shell is a plug-in end, and the other end of the outer shell is a conducting end. A nut is provided on the outside of the conducting end, and a cable is plugged into the center of the end face of the plug-in end. A snap-fit ​​fixing piece is provided on the outside of the arc of the plug-in end, and a pin is provided at the center of the inner part of the outer shell. An insulator is provided between the pin and the outer shell. By providing a plug-in end on the end face of the original straight tube outer shell, it is convenient to install the snap-fit ​​fixing piece, and at the same time, the inner core of the cable can be inserted therein, and it is also convenient to expand and separate the outer skin of the cable.

[0007] The cable is a multi-layer cable, comprising an inner core and an outer sheath. The inner core at one end of the cable is arranged on the outside of the end face of the outer sheath. The outer side of the outer sheath is clamped with a clamping fixture. The end face of the outer sheath is clamped into the extrusion cavity through the necking slope of the plug-in end. The inner core of the cable with the peeled outer sheath directly inserted into the connector can reduce the loss, and the peeled outer sheath can enter the extrusion cavity to be deformed and fixed, thereby ensuring the installation strength of the cable.

[0008] The end face of the necking slope is a shovel-shaped end face. The inner diameter of the necking slope is the same as the outer diameter of the inner core. After the cable is inserted into the outer shell through the necking slope, the outer skin on the outside of the inner core is expanded outward along the ramp, and the inner diameter of the necking slope allows only the inner core to enter and the outer skin to be discharged.

[0009] The shape of the snap-fit ​​fixing is cylindrical, and the material of the snap-fit ​​fixing is a hard material. A stepped variable diameter inner cavity is provided on the inner side of the snap-fit ​​fixing. The inner diameter of one end of the snap-fit ​​fixing is the same as the outer diameter of the plug-in end and is fixedly connected. A guide slope is provided between the fixing hook and the end face on the inner side of the other end of the snap-fit ​​fixing. The outer shell that is extruded outward is fixedly clamped by the snap-fit ​​fixing, and the outer skin is locked by the hook. The snap-fit ​​fixing made of hard material can prevent the snap-fit ​​fixing from being deformed, thereby improving the fixing strength of the locking.

[0010] The insulator is in the shape of a cylinder, with a through hole at the center of the insulator, a pin inside the through hole of the insulator, a protruding pin at one end of the insulator, the pin at the other end of the insulator is arranged inside the insulator, and a connecting circular groove is arranged on the end face of the other end of the insulator, and the connecting circular groove is connected to the end face of the inner core. By separately arranging a connecting circular groove on the end face of the insulator, the inner core can be firmly connected to the insulator, thereby facilitating the connection between the inner core and the pin.

[0011] Beneficial effects:

[0012] The outer skin of the cable is separated from the inner core in a locking neck slope horn-like manner, and then inserted into the extrusion cavity. The protruding and deformed outer skin is fixed by a clamping fixture, so that the cable can be quickly installed and fixed. The deformation and fixation of the outer skin can achieve rapid cable locking.

[0013] By providing a plug-in end on the end face of the original straight tube shell, it is convenient to install the clamping fixture, insert the inner core of the cable into it, and also facilitate the separation of the outer skin of the cable.

[0014] After the cable is inserted into the outer shell through the necking slope, the outer skin outside the inner core is expanded outward along the ramp, and the inner diameter of the necking slope allows only the inner core to enter and the outer skin to discharge.

[0015] The inner core of the stripped cable is directly inserted into the connector to reduce the loss, and the stripped cable can enter the extrusion cavity to be deformed and fixed, thereby ensuring the installation strength of the cable.

[0016] The outwardly expanded shell is fixed and clamped by means of a clamping fixture, and the outer skin is locked by means of a hook, and the clamping fixture made of a hard material can prevent the clamping fixture from being deformed, thereby improving the fixing strength of the locking.
