Description

Technical Field

[0001] The utility model relates to the field of threaded connection locking auxiliary tools, in particular to a torque tightening tool for an SMA electric connector. Background Art

[0002] In the microwave power circuit, the SMA connector can be connected to various stand-alone components such as antennas, filters, and power amplifiers to achieve signal input and output. The SMA connector has a threaded external connection interface with a hexagonal exterior. When connecting the SMA connector to the antenna stand-alone, the SMA cable plug (male) is generally connected to the SMA plug (female) on the equipment stand-alone, and then tightened with a manual wrench. Since the antenna will be tested wired or wirelessly when it is installed and powered on, the antenna stand-alone needs to be removed each time the state changes, and then the cable plug is removed. On the contrary, when installing the antenna stand-alone, the SMA cable plug is installed first and then the antenna stand-alone is installed. The SMA cable plug has a number of requirements when it is installed. Frequent removal of the antenna stand-alone due to the removal of the SMA cable plug will increase the number of removals of the antenna stand-alone, which will increase the probability of collision quality accidents of the antenna stand-alone to a certain extent. In addition, it is very difficult to further tighten the SMA connector with the existing manual wrench in some cases. For example, when the SMA connector is in a very narrow space, it is difficult for the manual wrench to reach into the narrow space and twist the SMA connector. Utility Model Content

[0003] After the antenna is installed, the antenna state needs to be changed for wired and wireless testing. Each time the state changes, the antenna unit needs to be removed and then the cable plug is removed. The installation is the opposite. The cable plug is installed first, and then the antenna unit is installed. The installation of the SMA cable plug is also required here. Frequent disassembly of the antenna unit due to the disassembly of the SMA cable plug will increase the number of disassembly of the antenna unit, which will increase the probability of collision quality accidents of the antenna unit to a certain extent. At the same time, in some cases, such as when the SMA connector is in a very small space, it is difficult for a manual wrench to reach into the small space to twist the SMA connector. At least one purpose or one aspect of the present application can solve the above problem. Specifically, a torque tightening tool for an SMA electrical connector is designed, and the specific technical solution adopted is:

[0004] A torque tightening tool for an SMA electrical connector comprises a connecting plate, one end of which is vertically provided with a clamping piece, the clamping piece having an inner square clamping slot, the clamping piece having an opening so that the clamping slot forms an open clamping slot, and the other end of the connecting plate is vertically provided with an outer square structural piece, the central axis of the structural piece, the central axis of the clamping piece and the plane where the connecting plate is located are parallel to each other and are in the same vertical plane, but not in the same horizontal plane.

[0005] Preferably, the clamping member is circular as a whole.

[0006] Preferably, the structural member has a circular hole inside.

[0007] Preferably, the clamping member and the structural member are located on the same side of the connecting plate.

[0008] Preferably, the cross section of the connecting plate is arc-shaped, and the center of curvature of the arc-shaped connecting plate is located on the side where the clamping member and the structural member are located.

[0009] Preferably, the connecting plate, the clamping parts and the structural parts are made of stainless steel.

[0010] The utility model is particularly suitable for the situation that the SMA connector is in a very small space by providing the torque tightening auxiliary tool. The tool can be used to remove specific cables separately, thereby reducing the number of times the antenna is disassembled and assembled, and reducing the possibility of quality accidents caused by collision of the antenna.

[0015] In order to clearly illustrate the technical features of the present invention, the present invention is described in detail below through specific implementation methods and in conjunction with the accompanying drawings.

[0016] In addition, in the description of the present invention, it should be understood that the terms "center", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "axial", "radial", "circumferential" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0017] like Figure 1-3As shown, an SMA electrical connector torque tightening tool is used for locking the SMA connector after connection in an antenna stand-alone machine, and mainly includes a connecting plate 1, a clamping member 2 is vertically provided at one end of the connecting plate 1, and the clamping member 2 has an inner square clamping slot 3, where the inner square clamping slot 3 should be a complete inner hexagonal clamping slot, and the clamping member 2 has an opening, so that the clamping slot 3 forms an open clamping slot, and therefore, the inner hexagonal clamping slot becomes a part of the inner hexagonal clamping slot 3, and the clamping slot 3 is set as an open structure in order to facilitate the clamping member 2 to be clamped in the position of the threaded external connection interface of the SMA connector from one side, and an outer square structural member 4 is vertically provided at the other end of the connecting plate 1, where the outer square structural member 4 is an outer hexagonal structural member, which is mainly used to provide a clamping position for a manual torque wrench. In order to avoid interference between the connecting plate 1 and the SMA cable when the clamping member 2 is clamped in the external hexagonal clamping position of the external connection interface of the SMA connector, the central axis of the structural member 4, the central axis of the clamping member 2 and the plane where the connecting plate 1 is located are parallel to each other and in the same vertical plane, but not in the same horizontal plane. In this way, there will be some distance between the connecting plate 1 and the clamping member 2 in the vertical direction. This distance can avoid the SMA cable and pass from the upper side of the SMA cable after the clamping member 2 is clamped in the external hexagonal clamping position of the SMA connector. Therefore, the tool can quickly tighten the SMA connector when the SMA connector is in a small space and a traditional manual wrench cannot enter.

[0018] When connecting, connect the SMA cable plug (male) to the SMA plug (female) on the device, then tighten it manually first, then clamp the hexagonal slot 3 of the connector 2 into the hexagonal clamping position of the SMA connector, and then use a manual wrench to clamp the structural member 4 at the other end of the connecting plate 1 to tighten the SMA connector.

[0019] Furthermore, the above-mentioned clamping component 2 is circular as a whole. Compared with a square clamping component 2, a circular clamping component 2 has a smaller area and occupies less space, and occupies even less space around the SMA connector.

[0020] Furthermore, the structure 4 has a circular hole 5 inside, and the setting of the circular hole 5 can allow other supporting components to pass through to support the end. The so-called supporting component is a supporting frame, on which a supporting shaft is provided. The supporting shaft can pass through the circular hole 5 to support the end, and then you only need to use a manual wrench to clamp the outer hexagonal sides of the structure 4 and screw the tool.

[0021] Furthermore, in this embodiment, the clamping member 2 and the structural member 4 are located on the same side of the connecting plate 1 .

[0022] In other embodiments, the above-mentioned clamping member 2 and structural member 4 may also be located on both sides of the connecting plate 1 .

[0023] Furthermore, in order to match the shapes of the structural parts 4 and the clips 2 at both ends, the cross-section of the connecting plate 1 is arc-shaped, and the center of curvature of the arc-shaped connecting plate 1 is located on the side where the clips 2 and the structural parts 4 are located. The arc-shaped connecting plate 1 will not have redundant parts at the edges or corners, and the arc-shape of the connecting plate 1 makes the entire tool smoother, without large edges and corners, and basically will not scratch the user.

[0024] Furthermore, the connecting plate 1, the clamping member 2 and the structural member 4 are made entirely of stainless steel, which has high strength and will not be torsionally deformed when being rotated and tightened.

[0025] The above-mentioned specific implementation manner cannot be used as a limitation on the protection scope of the present utility model. For those skilled in the art, any replacement, improvement or change made to the implementation manner of the present utility model falls within the protection scope of the present utility model.

[0026] The matters not described in detail in the present invention are all known technologies to those skilled in the art.
