Description

Technical Field

[0001] The utility model relates to an assembly tool, in particular to an assembly tool for a male plug of an SMA connector. Background Art

[0002] The SMA connector is a widely used small threaded coaxial connector with wide bandwidth, excellent performance, high reliability and long life. The SMA connector is suitable for connecting RF cables or microstrip lines in the RF circuits of microwave equipment and digital communication systems.

[0003] The common SMA connector male plug generally includes an outer shell body, an inner conductor, a ferrule and an insulating medium, all of which are cylindrical in shape. The outer shell body, the inner conductor, the contact head and the insulating medium are coaxially assembled. The ferrule is embedded in the interior of the outer shell body and partially extends out of the outer shell body. It is used for welding connection with the cable. The insulating medium is wrapped on the outer circle of the inner conductor and embedded in the coaxial cavity formed by the ferrule and the outer shell. The needle tip of the inner conductor protrudes out of the insulating medium. In order to facilitate the connection with the female plug, a sleeve is also provided on the outer shell. The sleeve is generally divided into a rectangular sleeve or a hexagonal sleeve.

[0004] In the actual assembly process, it is generally necessary to strip the insulation layer of the cable to be connected, and then weld the exposed cable to the ferrule. Finally, in order to protect the connection, a protective cover is riveted here to form a complete SMA connector male plug. In this process, there are the following problems:

[0005] 1. The length of the cable insulation stripped off depends entirely on the operator's experience. Too much or too little stripping often occurs, which is not conducive to connection with the ferrule.

[0006] 2. When welding, generally place the SMA connector male plug on the operating table, then hold the welding pen in one hand and bring the cable close to the ferrule with the other hand. If the connector male plug is not limited, it is easy to cause the connector male plug to move, resulting in low assembly efficiency;

[0007] 3. When riveting the protective cover, the male connector plug is placed vertically on the operating table. In this way, the male connector plug often tipps over during riveting, causing the male connector plug to be damaged. Summary of the invention

[0008] In view of the problems existing in the prior art, the utility model proposes an assembly tool for an SMA connector male plug. Through the tool, the SMA connector male plug to be welded can be clamped, which is beneficial to the welding of the cable and the ferrule, and the SMA connector male plug that needs to be riveted can be reliably restrained to facilitate the riveting of the protective cover. It can also control the length of the stripping of the cable insulation layer to improve the convenience of operation.

[0009] The technical solution of the utility model is:

[0010] The assembly tool of the SMA connector male plug comprises: a base, a first clamping block, a second clamping block and a positioning cylinder;

[0011] The first clamping block is connected to the base, and the second clamping block is connected to the top of the first clamping block through a connecting assembly. A clamping space for clamping the male plug of the SMA connector to be assembled is formed between the first clamping block and the second clamping block; the positioning cylinder is vertically connected to the base in a detachable manner, and a positioning cavity that is adapted to the sleeve shape of the male plug of the SMA connector to be assembled is provided on the positioning cylinder; and scale lines are also provided on the upper surface of the base.

[0012] Furthermore, the plane shape of the base is rectangular; the first clamping block and the second clamping block are located at the width edge of the base, and the scale lines are set at the length edge of the base; or the first clamping block and the second clamping block are located at the length edge of the base, and the scale lines are set at the width edge of the base.

[0013] Furthermore, the connection assembly includes two spaced connection units, each of which includes a screw, a washer and a butterfly nut. The screw is vertically arranged on the base, and one end of the screw passes through the first clamping block and the second clamping block in sequence and is screwed to the butterfly nut. The washer is sleeved on the screw and is located between the second clamping block and the butterfly nut. The screw is in sliding fit with the first clamping block and the second clamping block. In this structure, the setting of the connection unit serves the purpose of connecting the first clamping block and the second clamping block. Each connection unit includes a screw, a washer and a butterfly nut. The screw is fixed on the base. After the SMA connector male plug to be welded is placed in the clamping space, the butterfly nut is adjusted so that the clamping space formed between the second clamping block and the first clamping block can firmly clamp the SMA connector male plug, thereby avoiding welding failure caused by the looseness of the SMA connector male plug during welding, which greatly facilitates welding.

[0014] Furthermore, an elastic component for driving the first clamping block to approach the second clamping block is provided between the base and the first clamping block. In this structure, the elastic component is provided to drive the first clamping block to approach the second clamping block, so that the size of the clamping space can be conveniently adjusted without loosening the butterfly nut, and it is also convenient to place or remove the SMA connector male plug.

[0015] Furthermore, the elastic component includes two springs distributed at intervals, one end of each spring is connected to the base, and the other end of the spring is connected to the lower end of the first clamping block. In this structure, two springs are used so that the first clamping block can always maintain a tendency to move toward the second clamping block, thereby achieving the purpose of clamping the male plug of the SMA connector.

[0016] Furthermore, the first clamping block has a first end face and a second end face, the first end face is a plane, and the second end face is provided with a first arc-shaped portion; the second clamping block has a third end face and a fourth end face, the third end face is a plane, and the fourth end face is provided with a second arc-shaped portion; when the installation direction of the first clamping block and the second clamping block on the connecting assembly is adjusted so that the first end face and the third end face are matched, the clamping space is used to clamp the SMA connector male plug with a rectangular sleeve; when the installation direction of the first clamping block and the second clamping block on the connecting assembly is adjusted so that the second end face and the fourth end face are matched, the clamping space composed of the first arc-shaped portion and the second arc-shaped portion is used to clamp the SMA connector male plug with a hexagonal sleeve. In this structure, since the SMA connector male plug has different models, in order to achieve the purpose of reliable installation and clamping, a first arc portion is set on the second end face, and a second arc portion is set on the fourth end face, so that when the first arc portion and the second arc portion are matched, the clamping space formed is used to clamp the SMA connector male plug with a hexagonal sleeve, and when the first end face and the third end face of the plane are matched, they are used to clamp the SMA connector male plug with a rectangular sleeve, thereby achieving the purpose of reliable clamping.

[0017] Furthermore, a stud is provided at the bottom of the positioning cylinder, and when the SMA connector male plug needs to be riveted to the protective cover, the stud is screwed to the base; the cross section of the positioning cavity is rectangular or hexagonal, matching the cross section of the SMA connector male plug sleeve. This makes it easy to replace positioning cylinders of different specifications and to perform the riveting process.

[0018] Furthermore, the base is provided with a plurality of slots along the scale line direction, and blocks are detachably connected in the slots. In this structure, the blocks are connected to the slots at corresponding positions according to actual needs, thereby facilitating the abutment of the cable ends to facilitate the fixed-length cutting of the insulation layer.

[0019] Furthermore, a plurality of supporting legs are fixed to the bottom of the base.
