Description

Technical Field

[0001] This invention relates to the field of connector technology, and in particular to a connector manufacturing process. Background Technology

[0002] The ring conductor and connector of existing connectors are often manufactured using an integral processing technology, which involves selecting a whole conductor plate and then cutting the whole conductor plate multiple times to process it into an integral ring conductor and connector. This results in a lot of scrap material being generated during the multiple cutting and forming process, thereby increasing material consumption and waste, and thus increasing the manufacturing cost of connectors. Summary of the Invention

[0003] The main objective of this invention is to provide a connector manufacturing process that aims to reduce the production and processing costs of connectors.

[0004] To achieve the above objectives, the connector manufacturing process proposed in this invention includes the following steps:

[0005] Processed to form a ring conductor;

[0006] Processing to form connectors;

[0007] The connector is welded to one side of the annular conductor along the axial direction;

[0008] A center conductor is provided, and the center conductor and the annular conductor to which the connector is welded are placed into an injection mold for injection molding to form a connector; the connector includes an injection-molded insulating base for connecting the center conductor and the annular conductor.

[0009] Optionally, the step of forming a ring conductor includes: providing a tubular profile; and cutting the tubular profile to obtain the ring conductor.

[0010] Optionally, the step of forming a ring conductor includes: casting a metal material to obtain the ring conductor.

[0011] Optionally, the annular conductor and the connector are first electroplated, and then the connector is welded to one side of the annular conductor along the axial direction.

[0012] Optionally, the connector includes a first connector and a second connector that are fixedly connected to each other. The first connector is welded and fixed to the annular conductor, and the second connector is used for welding to the PCB board.

[0013] Optionally, the first connector is a connecting plate, and the second connector is a connecting column, wherein the connecting plate and the connecting column are formed by cold heading.

[0014] Optionally, the first connector is a first welding plate, and the second connector is a second welding plate, wherein the first welding plate and the second welding plate are formed by stamping and bending.

[0015] Optionally, the insulating base includes a first insulating base and a second insulating base that are fixedly connected to each other. The first insulating base is provided with a central groove and an annular groove that are spaced apart. The central conductor and the annular conductor are respectively located in the central groove and the annular groove.

[0016] Optionally, the second insulating base is provided with a first through hole and a second through hole, and the connector and the center conductor pass through the first through hole and the second through hole respectively to protrude from the surface of the second insulating base and are both connected to the PCB board.

[0017] Optionally, multiple annular conductors are provided, with each annular conductor corresponding to one annular groove and two connectors, and the multiple connectors and the central conductor are located on the same straight line.

[0018] The technical solution of this invention involves welding the connector onto the ring conductor. The welding process is mature, stable, and reliable, with short processing time.

[0033] Reference Figure 1 This invention proposes a connector manufacturing process, including the following steps:

[0034] Processed to form a ring conductor 21;

[0035] The connecting part 30 is formed by machining.

[0036] The connector 30 is welded to one side of the annular conductor 21 along the axial direction;

[0037] A center conductor 22 is provided, and the center conductor 22 and the annular conductor 21 to which the connector 30 is welded are placed into an injection mold for injection molding to form a connector; the connector includes an injection-molded insulating base for connecting the center conductor 22 and the annular conductor 21.

[0038] The technical solution of this invention involves welding the connector 30 onto the annular conductor 21. The welding process is mature, stable, and reliable, with short processing time. By processing the annular conductor 21 and the connector 30 separately, only materials of the corresponding size need to be processed into the corresponding annular conductor 21 and connector 30, thereby reducing the generation of scrap material during the processing of the annular conductor 21 and connector 30, thus reducing material loss and waste, and lowering the manufacturing cost of the connector. Furthermore, the annular conductor 21 and the center conductor 22 with the connector 30 welded on are injection molded to form a connector with an insulating base. The annular conductor 21 and the center conductor 22 are spaced apart within the insulating base for connection to different positions on the PCB board to transmit different signals. At the same time, the injection molding process also makes the fixed connection between the center conductor 22 and the annular conductor 21 and the insulating base stable and reliable. The welding and injection molding processes are mature and reliable, thereby further reducing the manufacturing cost of the connector.

[0039] The connector of this invention can be used in audio equipment for connecting PCB boards and other electronic devices. It can carry current, audio signals, control signals, power signals, etc. It can also be used in the field of electronic cigarettes for transmitting current, power signals, grounding signals, etc.

[0040] Understandably, the ring conductor 21 can be formed first, followed by the connector 30, or the connector 30 can be formed first, followed by the ring conductor 21. Of course, both can be done simultaneously, and the order of the two processes is not limited.

[0041] In one embodiment, the step of forming the ring conductor 21 includes: providing a tubular profile; cutting the tubular profile to obtain the ring conductor 21. The tubular profile is readily available and has a low cost. By directly processing the tubular profile to obtain the ring conductor 21, the manufacturing difficulty of the ring conductor 21 is greatly reduced, the processing technology is reduced, and the manufacturing cost is reduced.

[0042] In another embodiment, the step of forming the ring conductor 21 includes: casting a metal material to obtain the ring conductor 21. By casting the metal material to process the ring conductor 21 into a predetermined shape, the amount of machining of the casting is less, which can reduce the processing cost. At the same time, the production cost of casting is lower, thereby reducing the manufacturing cost.

[0043] Furthermore, the annular conductor 21 and the connector 30 are first electroplated, and then the connector 30 is welded to one side of the annular conductor 21 along the axial direction. Electroplating can obtain a decorative, protective and various functional surface layer on mechanical products, and can also repair worn and processed workpieces. Then the connector 30 is laser spot welded to the annular conductor 21.

[0044] Reference Figures 2 to 6 In this embodiment, the connector 30 includes a first connector 30 and a second connector 30 that are fixedly connected. The first connector 30 is welded and fixed to the annular conductor 21, and the second connector 30 is used for welding to the PCB board. The connector 30 connects the annular conductor 21 and the PCB board, which facilitates the welding and fixing of the annular conductor 21. At the same time, the materials of the annular conductor 21 and the PCB board may be different. Welding with two connectors 30 makes it easier to weld for different materials, thereby increasing the stability of the connection between the annular conductor 21 and the PCB board.

[0045] Furthermore, since the center conductor 22 is simple and convenient to process and has low manufacturing cost, the center conductor 22 on the connector does not need to be additionally welded to the connector 30, thereby reducing the processing of parts and the number of parts that need to be welded, thus reducing the production and manufacturing cost of the connector.

[0046] In one embodiment, the first connector 30 is a connecting plate 31, and the second connector 30 is a connecting post 32. The connecting plate 31 and the connecting post 32 are formed by cold heading. By setting it as a connecting plate 31, the welding area between the first connector 30 and the annular conductor 21 is increased, thereby improving the connection strength. At the same time, the connecting plate 31 and the connecting post 32 change the connection direction between the connector and the PCB, thereby facilitating the installation of the connector and improving the installation efficiency of the connector.

[0047] In another embodiment, the first connector 30 is a first welding plate 33, and the second connector 30 is a second welding plate 34. The first welding plate 33 and the second welding plate 34 are formed by stamping and bending. The bending and forming process is simple and has low processing cost. At the same time, the connection strength between the first welding plate 33 and the second welding plate 34 is high.

[0048] In this embodiment, the insulating base includes a first insulating base 11 and a second insulating base 12 fixedly connected to each other. The first insulating base 11 is provided with a central groove 112 and an annular groove 111 spaced apart. The central conductor 22 and the annular conductor 21 are respectively located in the central groove 112 and the annular groove 111. The central conductor 22, the annular conductor 21 and the plastic are injection molded to form the central groove 112 and the annular groove 111. Of course, in other embodiments, the temperature of the central conductor 22 and the annular conductor 21 can be increased and heat-melted into the first insulating base 11 to achieve a fixed connection.

[0049] Furthermore, the second insulating base 12 is provided with a first through hole 121 and a second through hole 122. The connector 30 and the center conductor 22 pass through the first through hole 121 and the second through hole 122 respectively, protruding from the surface of the second insulating base 12, and are both connected to the PCB board. The second insulating base 12 serves to further fix the connector 30 and the center conductor 22. Since the portion of the connector 30 and the center conductor 22 protruding from the first insulating base 11 is relatively long, the connection between the connector and the PCB board is easily loosened during shaking or soldering. Therefore, by setting the second insulating base 12, the stability of the connector 30 and the center conductor 22 is improved.

[0050] In this embodiment, multiple annular conductors 21 are provided, with one annular conductor 21 corresponding to one annular groove 111. The multiple annular conductors 21 are coaxially arranged and have different outer diameters. Each annular conductor 21 corresponds to at least one connector 30, and each connector 30 corresponds to one of the first insertion holes 121. By providing multiple annular conductors 21, the different information that the connector can transmit is further increased, improving the applicability of the connector. The transmitted information can be power signals, grounding signals, connection determination signals, etc., and can be changed according to the actual application scenario.

[0051] Specifically, one ring conductor 21 is provided for two connectors 30, and multiple connectors 30 are located on the same straight line as the center conductor 22. This makes it easier to sequentially solder and fix multiple connectors 30 and the center conductor 22 when the connector is soldered onto the PCB board, thereby improving the soldering efficiency of the connector. If they are not located on the same straight line, the direction needs to be adjusted when soldering different connectors 30, and the interference of other connectors 30 also needs to be considered during soldering, thereby reducing the soldering efficiency.

[0052] The above description is merely an optional embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made using the contents of the present invention's specification and drawings under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
