Description

Technical Field

[0001] The utility model relates to the technical field of connectors, and in particular provides a signal transmission DC connector. Background Art

[0002] Most existing connectors use a crimping structure. On the one hand, crimping connections require the use of special crimping tools, and the use of crimping tools has high requirements. The operation must be strictly in accordance with the prescribed crimping process, otherwise problems such as loose connections and broken wires and circuits are likely to occur. On the other hand, the inherent resistance of crimping connections is high, and higher-power connections need to withstand greater heating stress, which is prone to early failures. In addition, after crimping, existing crimping connectors will have incomplete contact between the wires, resulting in poor conductivity and poor stability. Summary of the Invention

[0003] In view of the shortcomings of the existing technology, the utility model provides a signal transmission DC connector with a simple structure, convenient operation, excellent conduction performance and good overall stability.

[0004] The utility model adopts the following technical solutions:

[0005] A signal transmission DC connector, characterized by comprising a main plastic part, a center terminal, a copper tube, and a rear plug; the main plastic part is riveted onto the interior of the copper tube; the center terminal is fixed to the interior of the main plastic part by a molding process; an inwardly recessed slot is provided in the middle of the back of the center terminal and the rear of the copper tube, and the rear plug is embedded along the slot.

[0006] In this example, preferably, the tail of the main plastic part is provided with a groove and a circular card hole, and the front end is provided with a circle of annular card flutes.

[0007] In this example, preferably, the copper tube wall is provided with a square positioning hole. When the main plastic part and the copper tube are assembled and connected, the positioning hole in the copper tube wall and the groove at the tail of the main plastic part correspond to each other and are riveted and fixed. The tail of the copper tube is also provided with a solder cup groove.

[0008] In this example, preferably, a fan-shaped welding portion is provided at the tail of the center terminal.

[0009] In this example, preferably, steps are formed on both outer sides of the rear plug, and fixing feet are respectively provided at the bottom of the two steps.

[0010] In this example, preferably, an inwardly recessed slot is provided in the middle of the center terminal and the back of the copper tube tail, and the steps on both sides of the rear plug fit the terminal welding part and are embedded along the slot, and the fixing feet are clamped into the circular clamping holes of the main plastic part, tightly pressed against the inner wall of the copper tube for connection.

[0011] After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art:

[0012] This utility model has a simple structure and exquisite design. The center terminal adopts a turning process, so that the connector can withstand a maximum current of 10A; a welding part is set at the tail of the center terminal, and the signal line is connected by welding technology, which changes the commonly used crimping structure into a welding structure, making the connection more firm, effectively solving the problem of easy disconnection and breaking of the wire after welding, and ensuring stable signal transmission in harsh environments.

[0020] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] like Figures 1 to 4As shown, the signal transmission DC connector described in this embodiment includes a main plastic part 1, a center terminal 2, a copper tube 3 and a rear plug 4; the tail of the main plastic part is provided with a groove 12 and a circular card hole 13, and the front end is provided with a circle of annular card ridges 11; the center terminal is provided with a fan-shaped welding part 21; the copper tube wall is provided with a positioning hole 32, and the tail end is provided with a solder cup groove 31; the outer sides of the rear plug are provided with steps 41, and the bottom of the two steps is provided with fixing feet 42.

[0022] like Figures 1 to 4 As shown, in this embodiment, the center terminal 2 is fixed inside the main plastic part 1 through the MOLDING process, the inner shell is formed by MOLDING, and the copper tube 3 is installed from the tail of the inner shell, abutting the annular card 11 of the main plastic part. The positioning hole 32 of the copper tube wall corresponds to the groove 12 at the tail of the main plastic part and is fixed by riveting. The steps 41 on both sides of the rear plug fit the terminal tail welding part 21 and are embedded in the slot (not marked) on the back of the copper tube welding cup groove 31. The fixing foot 42 is clamped into the clamping hole 13 at the tail of the main plastic part and pressed tightly to complete the assembly.

[0023] In this embodiment, the center terminal 2 is machined and combined with the main plastic part MOLDING, that is, the center terminal 2 is directly embedded in the main plastic part 1 during the molding process, so that the center terminal 2 is firmly combined with the main plastic part 1, ensuring that the connector can withstand a maximum current of 10A, avoiding gaps and looseness that may occur during the assembly process, improving the stability of the connection, and at the same time, reducing subsequent assembly steps and shortening the production cycle.

[0024] In this embodiment, the fan-shaped soldering portion 21 is located at the rear end of the center terminal 2 and is used for soldering signal wires. This replaces the common crimping structure with a soldering structure. This soldering technique connects the signal wire to the connector, eliminating the need for additional plugging and unplugging operations. This provides enhanced fixity and connection performance, effectively resolving the issue of wire breakage and disconnection after soldering. Furthermore, the soldered connector exhibits excellent vibration resistance, maintaining a stable connection in harsh operating environments and ensuring reliable signal transmission.

[0025] In the above embodiments, the description of each embodiment has its own focus. For parts that are not described or recorded in detail in a certain embodiment, reference can be made to the relevant description of other embodiments.

[0026] It should be noted that the above embodiments can be freely combined as needed. The above are only preferred embodiments of the present invention. It should be noted that those skilled in the art can make several improvements and modifications without departing from the principles of the present invention, and such improvements and modifications should also be considered within the scope of protection of the present invention.
