Description

Technical Field

[0001] This utility model relates to the field of radio frequency cable technology, and in particular to a structure for preventing incorrect insertion of radio frequency cables. Background Technology

[0002] With the widespread adoption and rapid development of electronic devices, radio frequency (RF) connections, as a crucial link in achieving high-speed and stable signal transmission between devices, are becoming increasingly important in terms of reliability and convenience. RF cable connectors, as the core component connecting RF cables to device ports, directly affect the signal quality and stability of the entire system.

[0003] However, existing RF cable connectors still face several technical bottlenecks in practical applications. First, mis-insertion is a common operational challenge. Some existing connector designs lack effective anti-mis-insertion mechanisms, and operators may mistakenly insert the connector backwards or incorrectly during installation or replacement due to negligence or environmental factors. Second, in many application scenarios, cables may be subjected to mechanical stresses such as tension, bending, or vibration. Some existing connector structures lack sufficient structural support and reinforcement at these connection points. Long-term or severe stress can easily cause the cable to break at the base of the port socket, or the cable to break at the connection point with the port socket due to uneven stress. Such failures not only cause signal interruptions and affect the normal operation of equipment, but also make repairs difficult, increasing maintenance costs and downtime.

[0004] Therefore, in order to enhance the mechanical strength and reliability of the connection between the cable and the port socket, we propose a mis-insertion RF cable connector structure. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing connector designs, such as the lack of an effective anti-misinsertion mechanism, and to propose an anti-misinsertion radio frequency cable connector structure.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: Design a mis-insertion prevention RF cable connector structure, including a port holder with a mating end, and a plurality of pins located in the mating end are embedded inside the port holder; A cable is also fixedly installed at the tail end of the port holder, and the wires of the cable are electrically connected to the needle core. The docking end is equipped with a foolproof part, and a reinforcing component can be detachably connected to the tail end of the port seat.

[0007] Furthermore, the anti-mistake part is an arc-shaped protrusion structure; The arc-shaped protrusion structure is formed on the inner wall of the docking end.

[0008] Furthermore, the reinforcing component includes a tube body that is inserted into the tail end of the port seat; A threaded portion is provided at the tail end of the tube body, and a plurality of deformation claws are distributed circumferentially at the tail end of the threaded portion. A locking nut is threadedly connected to the outer side of the threaded portion, and the inner side of the locking nut has an inner conical surface that stops the ends of the plurality of deformation claws.

[0009] Furthermore, the reinforcing component also includes: A clamping sleeve is placed between several of the deformation claws. The clamping sleeve has a T-shaped structure, and the tail end of the clamping sleeve extends in a direction away from the tube body. The cable passes through the clamping sleeve.

[0010] Furthermore, the clamping sleeve has a deformation opening along the axial direction on its outer side, and a number of stress-reducing holes are also provided on its outer side.

[0011] Furthermore, a plug-in section is provided at the tail end of the port seat, and at least one groove is provided on the outer side of the plug-in section, and a claw is formed in the groove. A locking hole is provided on the outside of the tube body, and the locking claw engages with the locking hole.

[0012] Furthermore, a guide groove is provided on the outer side of the insertion section, and a guide block that mates with the guide groove is formed in the inner ring of the tube body.

[0014] The present invention proposes a mis-insertion prevention RF cable connector structure, which has the following advantages: First, the design of the mis-insertion prevention part is used to prevent mis-insertion when the port socket is connected to other connectors. Second, the designed reinforcing component is connected to the tail end of the port socket to strengthen the protection between the cable and the port socket connection, which can avoid problems such as root breakage or tensile breakage at the cable-socket connection, thus further improving the applicability of the connector structure.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] Reference Figure 1-4 As an embodiment of the present utility model, it discloses a mis-insertion RF cable connector structure. Specifically, the connector structure includes a port seat 1 with a mating end 10, and a plurality of pin cores 2 located in the mating end 10 are embedded inside the port seat 1. The port holder 1 is also fixedly installed with a cable 3, and the wires of the cable 3 are electrically connected to the needle core 2. The docking end 10 is provided with a foolproof part 11, and a reinforcing part 4 can be detachably connected to the tail end of the port seat 1.

[0019] Specifically, the anti-foolproof part 11 in this utility model is an arc-shaped protrusion structure; The arc-shaped protrusion structure is formed on the inner wall of the mating end 10. The design of the anti-misfit part 11 is used to prevent mis-insertion when the port seat 1 and other mating joints are mated. Of course, the base of other mating joints should be provided with an inner recess that matches the anti-misfit part 11, so as to ensure the stability and accuracy of the mating process.

[0020] In some embodiments, the reinforcing component 4 of the present invention includes a tube body 41 inserted into the tail end of the port seat 1; A threaded portion 42 is provided at the tail end of the tube body 41. Several deformation claws 43 are distributed circumferentially at the tail end of the threaded portion 42. A locking nut 44 is threadedly connected to the outer side of the threaded portion 42. The inner side of the locking nut 44 has an inner conical surface 45 that stops the ends of several deformation claws 43.

[0021] Specifically, in this embodiment, the inner conical surface 45 abuts against several deformable claws 43 to contract, so that the deformable claws 43 can perform a clamping action. Of course, the entire reinforcing component 4 can be made of plastic to satisfy the purpose of deformable claws 43 being deformable.

[0022] Based on the above embodiments, the reinforcing component 4 in this embodiment further includes: A clamping sleeve 46 is placed between several of the deformation claws 43. The clamping sleeve 46 has a T-shaped structure and its tail end extends in a direction away from the tube body 41. The cable 3 passes through the clamping sleeve 46.

[0023] In other words, the reinforcing component 4 designed in this utility model is used to connect to the tail end of the port seat 1 to strengthen the protection between the cable 3 and the port seat 1, which can avoid problems such as root breakage or tension breakage at the cable-seat connection, thus further improving the applicability of the connector structure.

[0024] Specifically, in use, the tube body 41 can be connected to the port seat 1, and then the locking nut 44 mentioned above can be threaded on. The inner conical surface 45 on the inner side of the locking nut 44 abuts against multiple deformation claws 43 to deform, thereby driving the clamping sleeve 46 to deform and clamp and fix it on the outside of the cable 3. At this time, since the clamping sleeve 46 clamps and fixes the cable 3, the connection between the cable 3 and the port seat 1 can be effectively protected. Meanwhile, since the clamping sleeve 46 extends from the outer side of the phase tube body 41, it can protect the cable 3 within a certain length. Of course, the clamping sleeve 46 described in this embodiment can be made of rubber.

[0025] Preferably, in this embodiment, the clamping sleeve 46 has a deformation opening 47 on its outer side along the axial direction, and the clamping sleeve 46 also has a plurality of stress-reducing holes 48 on its outer side. The deformation opening 47 is used to meet the shrinkable requirement, and the stress-reducing holes 48 can reduce the weight of the entire clamping sleeve 46.

[0026] In some embodiments, a plug-in section 12 is provided at the tail end of the port seat 1 in this invention, and at least one groove is provided on the outer side of the plug-in section 12, and a claw 13 is formed in the groove. A locking hole 49 is provided on the outer side of the tube body 41, and the locking claw 13 engages with the locking hole 49. That is, in this utility model, the tube body 41 can be connected and fixed by engaging the locking hole 49 on the tube body 41 and the locking claw 13 on the insertion section 12.

[0027] Of course, the claw 13 described in this embodiment can also be made of plastic and integrally formed with the port seat 1. The claw 13 adopts an L-shaped structure design, and its side facing the tube body 41 is set as a sloping structure to avoid the insertion of the tube body 41.

[0028] Of course, in order to guide the insertion of the tube body 41 and avoid the problem of circumferential rotation of the tube body 41 after insertion, a guide groove 14 is also provided on the outer side of the insertion section 12 in this embodiment, and a guide block 410 that cooperates with the guide groove 14 is formed in the inner circle of the tube body 41. That is, the design of the guide groove 14 and the guide block 410 is used to realize the insertion positioning of the tube body 41, thereby improving the connection stability of the tube body 41.

[0029] Optionally, in this embodiment, a retaining ring 412 is slidably connected to the outer side of the tube body 41 via an elastic element 411. The retaining ring 412 covers the outer side of the locking hole 49. Specifically, the elastic element 411 in this embodiment can be set as a spring, which drives the retaining ring 412 to move. In use, the retaining ring 412 can cover the outer side of the locking hole 49, thus avoiding accidental contact with the locking claw 13 and causing disengagement. Of course, when it is necessary to separate the tube body 41 and the port seat 1, the retaining ring 412 is slid outward, and then the locking claw 13 is pressed to separate them. The operation is simple and convenient.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
