Detailed Description

The following description of the embodiments of the present application will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are only some, but not all, of the embodiments of the present application. All other embodiments, which can be made by those skilled in the art based on the embodiments herein without making any inventive effort, are intended to be within the scope of the present application. The various embodiments described below and their technical features can be combined with each other without conflict.

Based on this, it is necessary to provide a new solution for the SMA rf connector, so as to effectively improve the technical problems that in the welding process of the rf connector and the PCB body, the pins on the rf connector cannot be aligned with the pads on the PCB body accurately (i.e. offset in all directions occurs) in the conventional SMA rf connector, and thus the overall welding consistency is poor and the signal transmission performance of the SMA rf connector is affected.

In one embodiment, as shown in fig. 1, an SMA radio frequency connector 100 is provided in the embodiment of the present application, and the SMA radio frequency connector 100 may specifically include a PCB board welding end 110, where the PCB board welding end 110 is provided with at least two first pins 111, and the same side surfaces of the at least two first pins 111 are respectively provided with at least one positioning protruding portion 112.

It should be noted that, the PCB soldering terminal 110 is mainly used for completing the electrical connection with the PCB body by using a soldering manner. According to the actual signal transmission requirement, the welding end 110 of the PCB board is provided with a plurality of pins with different functions, and similarly, the PCB board body is also provided with pads (or welding areas) corresponding to the pins one by one, so as to realize one-to-one welding connection of the two. In order to cooperate with the surface of the corresponding side of the PCB body to form a three-dimensional mechanism for positioning two points and one surface, this example defines all the solder feet of the soldering surfaces on the same horizontal plane as the first pins 111, so that at least one positioning protruding portion 112 is respectively disposed on the same side surface (i.e. the soldering surface) of at least two first pins 111. Thus, the first pins 111 may be pins having the same function or pins having different functions.

Thus, according to the technical scheme of the embodiment of the application, at least two positioning points (namely, the positioning convex parts 112) can be formed at the PCB welding end 110 of the SMA radio frequency connector 100, and at least two positioning points can be positioned by a three-dimensional mechanism which at least forms two points on the surface of the corresponding side of the PCB in the welding process of the SMA radio frequency connector 110 and the PCB (not shown), so that in the welding process of the SMA radio frequency connector and the PCB, pins on the SMA radio frequency connector 110 can be accurately aligned with bonding pads on the PCB, the overall welding consistency of the pins is further ensured, and the signal transmission performance of the pins is improved.

In some examples, as shown in fig. 1, the positioning protruding portion 112 may be a cylinder or a prism, so as to perform a better positioning fit with the surface of the corresponding side of the PCB board through the columnar structure of the cylinder or the prism, so as to form a three-dimensional mechanism positioning of at least two points.

In some examples, as shown in fig. 1, at least two first pins 111 are located in a middle region of PCB board solder terminal 110. Generally, according to the actual signal transmission requirement, the PCB board welding end 110 is provided with a row of pins in the edge area and the middle area, wherein one row of pins is correspondingly welded with the bonding pads (or bonding areas) on the first side surface of the PCB board body, and the other row of pins is correspondingly welded with the bonding pads (or bonding areas) on the second side surface of the PCB board body. The row of pins located in the middle area of the PCB board welding end 110 is generally a ground pin, and the ground pins are set as the first pins 111, i.e. at least two first pins 111 are located in the middle area of the PCB board welding end 110, so that the positioning protruding portion 112 protruding on the first pin 110 does not affect the function of the first pin 112.

In some examples, as shown in fig. 1, the PCB board welding end 110 is specifically further provided with a second pin 113, and the second pin 113 is located in an edge area of the PCB board welding end 110. Based on the above description, the second pins 113 are another row of pins, typically non-ground pins, disposed at the edge area of the PCB solder terminal 110. The length of the second pin 113 is specifically set to be smaller than that of the first pin 111, preferably, the length of the second pin 113 is specifically set to be 0.3-0.5 mm, so that subsequent machining of the first pin 111 (i.e. forming of the positioning protruding portion 112) can be facilitated, and meanwhile, a limit mechanism for a PCB board body can be formed by matching with the first pin 111, so that the SMA radio frequency connector 100 is prevented from falling from the PCB board body in the welding process.

In some examples, as shown in fig. 1, the SMA radio frequency connector 100 of the embodiment of the application may specifically further include a screw connection end 120 connected to the PCB welding end 110, where a thread is disposed on an outer side surface of the screw connection end 120, so that in a connection process between different ports of the SMA radio frequency connector 100 for radio frequency products, connection stability of the SMA radio frequency connector is further enhanced by the thread, meanwhile, in order to implement a signal transmission function of the SMA radio frequency connector 100, a signal probe 114 is further disposed in a middle area of the PCB welding end 110, and a welding surface of the signal probe 114 and a welding surface of the first pin 111 may be located in the same horizontal plane, so as to implement corresponding welding connection with a welding pad (or a welding area) on a second side surface of the PCB body, and meanwhile, an extending direction of the signal probe 114 should be located on a central axis of the screw connection end 120.

In an embodiment, as shown in fig. 2 and fig. 3, the embodiment of the present application further provides an SMA radio frequency connector 1, where the SMA radio frequency connector 1 may specifically include a PCB board 200 and the SMA radio frequency connector 100 in the foregoing embodiment, at least two welding areas set in one-to-one correspondence with at least two first pins 111 are provided on a surface of one side of the PCB board 200, and a positioning hole 210 set in one-to-one correspondence with at least one positioning boss 112 is provided on each welding area.

It should be noted that, the PCB body 200 has an interconnection circuit therein to realize a preset electrical connection between components on the PCB body 200, thereby realizing a corresponding circuit function. The PCB body 200 may be specifically manufactured by using a copper-clad plate (a product obtained by laminating a glass fiber cloth and a copper foil together with an epoxy resin as a fusion agent), and then performing etching, electroplating, and lamination of a plurality of layers of boards. The PCB body 200 is provided with at least two soldering lands corresponding to the at least two first pins 111 one by one, and other soldering lands corresponding to the second pins 113 and the signal probes 114, respectively.

In this way, according to the technical scheme of the embodiment of the application, at least two positioning points (i.e. the positioning protruding portions 112) can be formed at the PCB welding end 110 of the SMA radio frequency connector 100, and at least two positioning points can be engaged with at least two positioning holes 210 on the surface of the corresponding side of the PCB 200 in a one-to-one correspondence manner in the welding process of the SMA radio frequency connector 110 and the PCB 200, so as to form a three-dimensional mechanism positioning of at least two points, thus, in the welding process of the SMA radio frequency connector 100 and the PCB 200, pins on the SMA radio frequency connector 110 can be accurately aligned with bonding pads (i.e. welding areas) on the PCB 200, and further, the overall welding consistency is ensured, and the signal transmission performance is improved.

In some examples, as shown in fig. 2 and 3, the height of the positioning protruding portion 112 may be 0.4-0.6 times the thickness of the PCB board 200, so that when the positioning protruding portion 112 is correspondingly snapped into the corresponding positioning hole 210, the top end of the positioning protruding portion 112 may be hidden in the corresponding positioning hole 210, without causing any abrupt feeling to the other side surface of the PCB board 200 and affecting the flatness of the soldering surface.

In some examples, as shown in fig. 2 and 3, the inner diameter of the positioning hole 210 may be specifically smaller than the outer diameter of the positioning protrusion 112 by 10-20 micrometers, so that when the positioning protrusion 112 is correspondingly snapped into the corresponding positioning hole 210, the positioning hole 210 and the positioning protrusion 112 are tightly mounted, so as to further prevent the SMA rf connector 100 from falling from the PCB body 200 during the soldering process.

In one embodiment, the embodiment of the present application further provides an electronic device, which may specifically include the SMA rf connector 100 in the foregoing embodiment or the SMA rf connector 1 in the foregoing embodiment. In this way, the welding consistency of the whole SMA radio frequency connector 100 or SMA radio frequency connector 1 of the electronic device can be ensured, and the signal transmission performance of the electronic device can be improved.
