Abstract
Description
Technical Field
[0001] This utility model relates to the field of radio frequency coaxial connector technology, and in particular to a radio frequency coaxial connector that is resistant to detachment. Background Technology
[0002] Radio frequency coaxial connectors, also known as RF connectors, are an important component in radio frequency / microwave signal transmission. They are mainly used to connect coaxial cables, microstrip lines, or other RF transmission lines to achieve electrical connection, isolation, or conversion between different types of transmission lines, so as to realize interconnection between devices / modules and effectively transmit radio frequency and microwave signals. They are mechatronic products that act as bridges.
[0003] RF coaxial connectors are widely used in wireless communication, broadcasting, television, radar and other fields.
[0004] Currently, in common designs of RF coaxial connectors, a threaded connection mechanism is generally used between the male and female heads to achieve mechanical coupling and electrical contact. However, this connection method has certain limitations in practical applications: because it relies on thread engagement for fixation, it is prone to relative rotation or loosening under dynamic conditions such as vibration and torque, resulting in decreased connection stability and even accidental detachment, which in turn affects the reliability of signal transmission and the overall operational safety of the equipment.
[0005] To address this, we propose a non-detachable RF coaxial connector. Utility Model Content
[0006] The purpose of this invention is to address the shortcomings of existing technologies by proposing an anti-detachment radio frequency coaxial connector.
[0007] To achieve the above objectives, the present invention adopts the following technical solution: an anti-detachment radio frequency coaxial connector, comprising a male connector and a female connector, wherein two mounting plates are symmetrically provided at the handle of the male connector, and both mounting plates are fixed to the male connector by two first bolts;
[0008] Both of the aforementioned mounting plates include a connecting seat, and a perforated long plate is fixedly connected to the side of the connecting seat away from the male connector;
[0009] Two anti-disengagement buckles are symmetrically provided at the handle of the connecting female head, and both anti-disengagement buckles are fixed to the connecting female head by two second bolts;
[0010] Both anti-disengagement buckles include a base, a spring plate is fixedly installed on the side of the base away from the connecting female head, an arc-shaped buckle is fixedly connected to the side of the spring plate away from the connecting female head, and an L-shaped pressure plate is fixedly connected to one end of the spring plate.
[0011] Furthermore, the handle of the male connector is symmetrically provided with four first screw holes, and the first screw holes are threadedly connected to the first bolts, providing a stable and symmetrical mounting base for the installation of the buckle plate, ensuring the structural strength and force balance after installation, and preventing shaking due to single-point force.
[0012] Furthermore, the top of the connector has two symmetrical first mounting holes that extend to the bottom, and the first mounting holes match the first bolts, so that the mounting plate can fit tightly against the surface of the male handle and form a rigid connection after being tightened by bolts.
[0013] Furthermore, the perforated long plate includes an arc-shaped plate, and the arc-shaped plate is fixedly connected to the connecting seat. A locking hole extending through to the bottom is provided on one side of the top of the arc-shaped plate, and the locking hole matches the arc-shaped buckle. The locking hole can accommodate the arc-shaped buckle, so as to achieve reliable fastening and locking.
[0014] Furthermore, four second screw holes are symmetrically provided at the handle of the connecting female head, and the second screw holes are threadedly connected to the second bolts. The symmetrically distributed screw hole design ensures the installation stability of the anti-disengagement mechanism.
[0015] Furthermore, the base includes a bottom plate, which is fitted to the outer wall of the connecting female head. The top of the bottom plate has two symmetrical second mounting holes that extend to the bottom, and the second mounting holes are matched with second bolts. The outer surface of the bottom plate is symmetrically fixedly connected to two side stops. The bottom plate ensures the flatness of the installation, while the side stops on both sides can effectively limit the lateral displacement of the spring sheet when it is compressed.
[0016] Furthermore, the spring sheet includes an installation section, which is fixedly connected to the base plate and located between two side stops. One end of the installation section is fixedly connected to an arc-shaped section, and the end of the arc-shaped section away from the installation section is fixedly connected to a horizontal section. The arc-shaped buckle and the L-shaped pressure plate are both fixedly connected to the horizontal section. The spring sheet structure utilizes the elastic deformation of the arc-shaped section to provide a stable rebound force.

Detailed Implementation
[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0029] like Figures 1-6As shown, a non-detachable radio frequency coaxial connector is disclosed, including a male connector 1 and a female connector 3. Two mounting plates 2 are symmetrically provided at the handle of the male connector 1. Both mounting plates 2 are fixed to the male connector 1 by two first bolts 6. Four first screw holes 11 are symmetrically provided at the handle of the male connector 1, and the first screw holes 11 are threadedly connected to the first bolts 6. The first bolts 6 can be matched with anti-loosening washers for installation to ensure the stability of the connection of the first bolts 6.
[0030] Both mounting plates 2 include a connecting seat 21. A perforated long plate is fixedly connected to the side of the connecting seat 21 away from the connecting male head 1. The top of the connecting seat 21 has two symmetrical first mounting holes 22 that extend to the bottom and match the first bolt 6. The perforated long plate includes an arc plate 23 and is fixedly connected to the connecting seat 21. A locking hole 24 extending to the bottom is provided on one side of the top of the arc plate 23 and matches the arc buckle 43. The arc plate 23 and the connecting seat 21 are designed as an integral unit to ensure structural strength.
[0031] Two anti-disengagement buckles 4 are symmetrically provided at the handle of the connecting female head 3. Both anti-disengagement buckles 4 are fixed to the connecting female head 3 by two second bolts 5. Four second screw holes 31 are symmetrically provided at the handle of the connecting female head 3, and the second screw holes 31 are threadedly connected to the second bolts 5. The second bolts 5 can be matched with anti-loosening washers to ensure the stability of the connection of the second bolts 5.
[0032] Both anti-disengagement buckles 4 include a base. A spring plate is fixedly installed on the side of the base away from the connecting female head 3. The spring plate is made of beryllium bronze, which has extremely high fatigue strength and excellent elasticity. An arc-shaped buckle 43 is fixedly connected to the side of the spring plate away from the connecting female head 3. An L-shaped pressure plate 45 is fixedly connected to one end of the spring plate. The base includes a bottom plate 47, which fits against the outer wall of the connecting female head 3. Two second mounting holes are symmetrically opened on the top of the bottom plate 47, extending to the bottom, and these second mounting holes match the second bolts 5. Two side stops 41 are symmetrically fixedly connected to the outer surface of the base plate 47. The spring sheet includes a mounting section 46, which is fixedly connected to the base plate 47 and located between the two side stops 41. An arc-shaped section 42 is fixedly connected to one end of the mounting section 46, and a horizontal section 44 is fixedly connected to the end of the arc-shaped section 42 away from the mounting section 46. An arc-shaped buckle 43 and an L-shaped pressure plate 45 are both fixedly connected to the horizontal section 44. The end of the arc-shaped buckle 43 is chamfered to facilitate sliding into the lock hole 24 when locked, achieving a smooth "buckle" feel.
[0033] Working principle: First, press the L-shaped pressure plates 45 on the two anti-disengagement buckles 4 at the same time. Pressing down the L-shaped pressure plates 45 will apply a downward force to the spring sheet through the horizontal section 44, overcoming the spring sheet's rebound force and making the arc-shaped buckle 43 approach the connecting female head 3. Then, as in normal operation, screw the threaded interface of the connecting male head 1 into the threaded interface of the connecting female head 3 to complete the initial electrical connection and mechanical fixation.
[0034] Subsequently, the L-shaped pressure plate 45 is released, and the rebound force of the spring plate will drive the arc-shaped buckle 43 to be tightly fastened in the lock hole 24, forming a solid mechanical interlock. The two symmetrical additional buckle plates 2 ensure the balance of the locking force, which greatly enhances the stability of the connection.
[0035] Once locked, the male connector 1 and female connector 3 are not only connected by threads, but also mechanically "bound" together by the fastener 2 and anti-disengagement clip 4. When external equipment is subjected to vibration or accidental pulling, the resulting loosening force will act directly on this mechanical interlocking mechanism. Because this mechanism is a rigid interlocking structure, rather than relying on friction, it can effectively resist the tangential force that would cause the threaded connection to rotate and loosen, thus fundamentally preventing the connector from falling off.
[0036] When it is necessary to separate the connector, first perform the unlocking operation by pressing the L-shaped pressure plates 45 on both anti-disengagement latches 4. Pressing down the L-shaped pressure plates 45 will apply a downward force to the spring sheet through the horizontal section 44, overcoming the spring sheet's rebound force, causing the arc-shaped latch 43 to disengage from the locking hole 24 of the latch plate 2, thereby releasing the mechanical interlock. After that, it can be separated from the female connector by rotating the male handle, just like a normal connector, to loosen the threaded connection.
[0037] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
