Description

Technical Field

[0001] This utility model relates to the field of radio frequency coaxial cable assembly technology, specifically a disassembly and assembly tool for an ultra-small SMP type radio frequency coaxial connector. Background Technology

[0002] Radio frequency (RF) coaxial cable assemblies are a commonly used type of microwave signal transmission cable assembly. They have advantages such as wide bandwidth, superior electrical performance, flexibility, and ease of use, and are widely used in testing systems, instrumentation, microwave communications, and aerospace. For example, microwave components such as TR components, subarray components, and channel components of phased array radar and millimeter-wave radar are core components of active phased array radar. They mostly use RF coaxial cable assemblies to achieve low-loss and high-efficiency signal transmission between boards, modules, and systems and subsystems. In particular, SMP series connectors are widely used in this field.

[0003] The SMP series socket is an ultra-miniature push-in RF coaxial connector, characterized by its small size, light weight, excellent shock resistance, and wide operating bandwidth. Some SMP coaxial microstrip connectors installed on microwave modules use a female interface and are fixed to the cavity by soldering. However, this method can lead to connector failure, and SMP coaxial microstrip connectors must be replaced when they fail. Currently, the simplest replacement method is local heating, using a hot air gun to heat the failed SMP coaxial microstrip connector until the solder melts, allowing for removal. However, this method, especially in confined spaces, is difficult to operate with tweezers or pliers due to the limited space. Furthermore, manual operation without tools can easily damage the connector or PCB board during separation. Utility Model Content

[0004] To address the aforementioned issues, this utility model provides a disassembly and assembly tool for an ultra-small SMP type RF coaxial connector, which makes it easier to remove the connector without damaging it, enabling convenient testing and improving work efficiency.

[0005] This utility model adopts the following technical solution: a disassembly and assembly tool for an ultra-small SMP type RF coaxial connector, including a limiting outer cylinder, a clamping member, and a push-pull seat. One end of the clamping member and the push-pull seat respectively extends into the inner cavity of the limiting outer cylinder, and the other end of the clamping member and the push-pull seat are respectively exposed outside the limiting outer cylinder. The push-pull seat is located outside the clamping member and has a hollow structure. The clamping member and the push-pull seat are fixedly connected inside the limiting outer cylinder. A spring is fitted on the clamping member between the limiting outer cylinder and the push-pull seat. The clamping end of the clamping member has several milled grooves along the circumference to form an elastic expansion structure. The outer wall of the clamping end of the clamping member is in contact with the inner wall of the limiting outer cylinder, and the contact surfaces between the clamping member and the limiting outer cylinder are corresponding inclined surfaces.

[0006] Furthermore, the cross-section of the limiting outer cylinder is cross-shaped, the cross-section of the push-pull seat is T-shaped, the outer diameter of the clamping member located inside the limiting outer cylinder is smaller than the inner diameter of the push-pull seat, and the outer diameter of the push-pull seat is smaller than the inner diameter of the limiting outer cylinder.

[0007] Furthermore, the clamping member located inside the limiting outer cylinder is provided with an external thread on its outer side, and the inner wall of the push-pull seat is provided with an internal thread, and the external thread of the clamping member is connected to the internal thread of the push-pull seat.

[0008] Furthermore, the inclination of the inclined plane is 10° to 15°;

[0009] Furthermore, the contact surface between the clamping member and the limiting outer cylinder is gradually tapered and inclined from the outside to the inside.

[0010] The advantages of this utility model are that it has a compact structure and small size, making it suitable for use in confined spaces. It allows for easy assembly and disassembly of connectors without the need for auxiliary tools such as tweezers or pliers, saving time and effort. It is portable and easy to operate by hand, and has good practical value. Attached Figure Description

[0012] Figure 2 This is a schematic diagram of the structure of this utility model and its interlocking with an SMP connector. Detailed Implementation

[0013] like Figures 1-2As shown, this utility model discloses a disassembly and assembly tool for an ultra-small SMP type RF coaxial connector, comprising a limiting outer cylinder 2, a clamping member 1, and a push-pull seat 4. One end of the clamping member 1 and the push-pull seat 4 extends into the inner cavity of the limiting outer cylinder 2 from both ends, while the other end of the clamping member 1 and the push-pull seat 4 are exposed outside the limiting outer cylinder 2. The push-pull seat 4 is located outside the clamping member 1 and has a hollow structure. The clamping member 1 and the push-pull seat 4 are fixedly connected inside the limiting outer cylinder 2. A spring 3 is fitted on the clamping member 1. The clamping end of the clamping member 1 has several milled grooves 5 along the circumferential direction to form an elastic expansion structure. The outer wall of the clamping end of the clamping member 1 is in contact with the inner wall of the limiting outer cylinder 2. The contact surfaces 11 between the clamping member 1 and the limiting outer cylinder 2 are all corresponding inclined surfaces. Furthermore, the contact surfaces 11 between the clamping member 1 and the limiting outer cylinder 2 are gradually tapered and inclined from the outside to the inside, that is, the inclination of the inclined surface is 10°, which can ensure that the expansion port is smoothly compressed and tightly contacted with the SMP connector 6 under the action of the spring 3.

[0014] The cross-section of the limiting outer cylinder 2 is cross-shaped, and the cross-section of the push-pull seat 4 is T-shaped. The outer diameter of the clamping member 1 located inside the limiting outer cylinder 2 is smaller than the inner diameter of the push-pull seat 4, and the outer diameter of the push-pull seat 4 is smaller than the inner diameter of the limiting outer cylinder 2. The clamping member 1 located inside the limiting outer cylinder 2 has an external thread on its outer side, and the inner wall of the push-pull seat 4 has an internal thread 41. The external thread of the clamping member 1 is connected to the internal thread 41 of the push-pull seat 4 to ensure the connection strength.

[0015] The assembly and disassembly process of this utility model is as follows: During use, after clamping the limiting outer cylinder 2 with your fingers, push the push-pull seat 4 into the inner cavity, compressing the spring 3. This causes the clamping end of the clamping member 1 to protrude from the limiting outer cylinder 2 and open its expansion port. At this time, the SMP connector 6 can be placed into the clamping end of the clamping member 1. Then, release the push-pull seat 4. Due to the spring 3's rebound, the clamping end of the clamping member 1 will retract into the limiting outer cylinder 2. At this time, because the inner diameter of the contact surface 11 of the limiting outer cylinder 2 is reduced, the clamping end of the clamping member 1 tightens and expands. The clamping end of the clamping member 1 is designed with a structure according to the interface standard of the SMP connector 6 to better connect with the SMP connector 6. Therefore, the SMP connector 6 can be clamped in the clamping end of the clamping member 1, so that the SMP connector 6 can be installed and removed. After installation and removal, when it is necessary to remove the disassembly tool for the SMP connector 6, simply push the push-pull seat 4 into the inner cavity again. The spring 3 will be compressed, and the expansion port of the clamping end of the clamping member 1 will expand again. At this time, the disassembly tool can be removed.

[0016] In summary, this utility model only requires the setting of a limiting outer cylinder 2, a clamping component 1, a push-pull seat 4, and a spring 3. The clamping component 1, the push-pull seat 4, and the spring 3 are all assembled inside the limiting outer cylinder 2, making the structure more compact, reducing the volume, reducing the number of parts, and making it easier to process. It is comparable in size to the connector and is suitable for use in confined spaces. It can quickly plug and unplug the SMP connector 6, saving time and effort. It is portable and easy to operate by hand, without the need for auxiliary tools such as tweezers or pliers to disassemble and assemble the connector, ensuring that the connector will not be damaged.
