Description

Technical Field

[0001] This utility model relates to the field of SMP joint welding technology, specifically to a 45° SMP joint welding positioning fixture. Background Technology

[0002] SMP connectors (Radio Frequency Coaxial Connectors) play a crucial role in microwave circuits by connecting or disconnecting coaxial cables, microstrip circuits, and transmitting signals. They are essential functional components for RF signal connection and energy transfer, and are also important input / output connectors for microwave circuits. Due to their excellent broadband transmission characteristics and convenient and reliable connection methods, SMP connectors are evolving towards higher density, higher reliability, functionalization, and integration. SMP connectors are also used for soldering.

[0003] The SMP connector involved in this application is a 45° SMP connector. Designing the connector part of the SMP connector at a 45° angle can reduce the connector height and reduce cable connections, thereby improving integration and making it suitable for use in RF antennas. However, when soldering the 45° SMP connector to the PCB board, it is generally soldered directly without external positioning fixtures. This is especially true for 45° SMP connectors, where positioning is more difficult, which can lead to soldering misalignment when soldering the 45° SMP connector to the PCB board.

The PCB board to be welded to the 45° SMP connector is fixed between the cover plate and the support, thus ensuring that the welding points of the PCB board correspond to the welding points of the 45° SMP connector. At this time, the PCB board is limited by the cover plate, and the 45° SMP connector is limited by the limiting component, which ensures the stability of the welding.

[0008] As a further embodiment of this utility model: the strong magnetic component includes a plurality of upper magnet blocks mounted on the cover plate and a plurality of lower magnet blocks mounted on the top of the support, wherein the upper magnet blocks and the lower magnet blocks are positioned correspondingly.

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below in conjunction with the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0026] Reference Figure 1 , Figure 2 and Figure 3 A 45° SMP connector welding positioning fixture includes a support 1, a cover plate 3, and a limiting component 5. The limiting component 5 is installed inside the support 1 to fix the position of the 45° SMP connector 4. The cover plate 3 is located above the support 1, and the two are magnetically fixed together by a magnet. The PCB board 2 to be welded to the 45° SMP connector 4 is limited between the cover plate 3 and the support 1. After the 45° SMP connector 4 and the PCB board 2 are welded, the cover plate 3 can be removed, and then the 45° SMP connector 4 and the PCB board 2 can be taken out.

[0027] Reference Figure 2 , Figure 3 and Figure 4The support 1 has a rectangular structure. A groove for placing the 45° SMP connector 4 is vertically opened at the middle position inside the support 1. A push plate 501 and a lower spring 502 inside the limit assembly 5 are installed at the lower part of the groove. The 45° SMP connector 4 is located at the upper part of the groove. The top of the groove is a welding port 103. The 45° SMP connector 4 can enter and exit the groove through the welding port 103.

[0028] Furthermore, four recessed grooves are provided on the top of the support 1 and on the outer ring of the weld joint 103. Four lower magnet blocks 102 are provided in each recessed groove. It should be noted that the number of lower magnet blocks 102 can be determined according to the actual situation of the support 1. This application does not limit it, but only one set of embodiments is given. A side push rod hole 101 is provided on one side of the support 1. The side of the side push rod hole 101 facing the groove body is connected to the spring limiting hole 104. The spring limiting hole 104 is coaxial with the side push rod hole 101 and is connected to the groove body.

[0029] Reference Figure 2 The cover plate 3 has a circular ring structure and four recessed grooves. Each recessed groove contains four upper magnet blocks 301. It should be noted that the number of upper magnet blocks 301 can be determined according to the actual situation of the cover plate 3. This application does not limit this number, but only provides one embodiment. The number of upper magnet blocks 301 is the same as the number of lower magnet blocks 102. The positions of the upper magnet blocks 301 and the lower magnet blocks 102 are corresponding. The magnetic connection between the upper magnet blocks 301 and the lower magnet blocks 102 can fix the cover plate 3 to the upper part of the support 1. When soldering, the PCB board 2 can be placed at the corresponding position on the top of the support 1 first. After the position is fixed, the cover plate 3 is placed on the PCB board 2. At this time, the magnetic connection between the upper magnet blocks 301 and the lower magnet blocks 102 can ensure the stability of the PCB board 2.

[0030] Reference Figure 2 The connection part of the 45° SMP connector 4 is provided with a 45° inclined surface, and the connector is provided on the 45° inclined surface. The other end of the 45° SMP connector 4 is a soldering end, which is used to solder to the PCB board 2.

[0031] Reference Figure 2 The limiting component 5 includes a push plate 501, a lower spring 502, a side push rod 503, a side spring 504, and a clamping block 505. The lower spring 502 is installed at the bottom of the support 1 groove, and the push plate 501 is installed above the lower spring 502. The bottom of the 45° SMP connector 4 can contact the push plate 501.

[0032] The side push rod 503 passes through the side push rod hole 101. A side spring 504 is sleeved on the outside of the side push rod 503. The side spring 504 is located in the spring limiting hole 104. Since the diameter of the spring limiting hole 104 is larger than the diameter of the side push rod hole 101, the side spring 504 is restricted in the spring limiting hole 104 and will not move out of the side push rod hole 101. A clamping block 505 is provided at the end of the side push rod 503 near the groove body. The clamping block 505 can contact one side of the 45° SMP connector 4.

[0033] The end of the clamping block 505 near the 45° SMP connector 4 has a conical structure. When the 45° SMP connector 4 moves down, it will press against the clamping block 505 and drive the clamping block 505 to move backward.

[0034] When the limiting component 5 limits the 45° SMP connector 4, the clamping block 505 limits the 45° SMP connector 4 from one side under the action of the side spring 504; the push plate 501 limits the 45° SMP connector 4 from the bottom under the action of the lower spring 502, thereby achieving full limiting of the 45° SMP connector 4.

[0035] The specific operating principle of this application is as follows:

[0036] During operation, first place the 45° SMP connector 4 into the corresponding groove of the support 1; when placing it in, the elbow of the 45° SMP connector 4 will press the clamping block 505 to move backward, the side spring 504 behind the clamping block 505 will be compressed, and the clamping block 505 will move backward; after placement, the elbow of the 45° SMP connector 4 will be fully inserted into the groove, and the compressed side spring 504 will force the clamping block 505 to move forward, clamping the 45° SMP connector 4 so that it cannot wobble.

[0037] Then, the PCB board 2 is placed on the support 1. The PCB board 2 has solder holes corresponding to the solder pins of the 45° SMP connector 4, so that the solder holes and solder pins correspond. Then, the cover plate 3 is placed on it. The cover plate 3 is provided with an upper magnet block 301. The upper magnet block 301 and the lower magnet block 102 on the support 1 attract each other, so that the PCB board 2 is tightly attached to the support 1.

[0038] The lower spring 502 inside the support 1 pushes the push plate 501, causing it to press the 45° SMP connector 4 tightly against the PCB board 2. This completes the positioning of the 45° SMP connector.

[0039] After soldering is complete, remove cover plate 3, and you can take off the soldered PCB board.

[0040] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
