Description

Technical Field

[0001] This utility model belongs to the field of communication terminals, specifically relating to an integrated stamped terminal for a DC socket. Background Technology

[0002] In the field of charging equipment, the communication terminal, as the core connecting component between the socket and the charging gun, is responsible for transmitting information such as charging status, protocol, and identification. Its performance and manufacturing cost directly affect the reliability and economy of charging products.

[0003] Traditional communication terminals are generally manufactured using machining or cold heading processes:

[0004] In terms of materials, copper is mostly used. Although it has excellent conductivity, the material cost is high. Moreover, the processing requires multiple machining processes such as cutting and milling, resulting in low material utilization and long processing cycle (for example, a single terminal needs to be clamped and cut multiple times, taking several hours).

[0005] In terms of surface treatment, traditional terminals need to be electroplated separately after processing (such as nickel plating or gold plating) to improve conductivity and oxidation resistance. Single-piece electroplating requires multiple steps such as degreasing, pickling, electroplating, and cleaning. This not only results in high electroplating costs (accounting for about 20% to 30% of the cost of a single terminal), but also low efficiency during mass production (limited capacity of single electroplating batches and long waiting time).

[0006] In terms of structural design, traditional terminals are mostly split structures, requiring the assembly of multiple parts (such as elastic contacts and connecting parts) to achieve their functions. The large number of parts leads to high assembly complexity, and the lack of integrated elastic contact design makes them prone to poor contact due to insufficient contact pressure when connected to plugs and charging guns, affecting the stability of signal transmission.

[0007] In terms of production automation, machining and cold heading processes rely on manual operation or semi-automated equipment, making it difficult to achieve fully automated production. This results in low production efficiency and difficulty in ensuring accuracy consistency, leading to a high defect rate. Utility Model Content

[0008] The purpose of this invention is to provide an integrated stamped terminal for DC sockets, which solves the problems of high processing cost and low processing efficiency of traditional communication terminals mentioned in the background art through structural optimization.

[0009] To achieve the above objectives, this utility model provides the following technical solution:

[0010] An integrated stamped terminal for a DC socket includes a communication terminal. One side of the communication terminal has several protrusions, and the other side of the communication terminal has several grooves. The protrusions and grooves match. The cross-section of the communication terminal is arc-shaped. Both ends of the communication terminal are provided with several elastic elements. A dividing groove is provided on the communication terminal around the elastic elements.

[0011] Preferably, the elastic element is inclined inward.

[0012] Preferably, the bottom of the communication terminal is provided with an elastic element two, and the communication terminal around the elastic element two is provided with a dividing groove two.

[0013] Preferably, the second elastic element is inclined outward.

[0014] Preferably, a support column is movably disposed inside the communication terminal, and a limit plate is provided at both ends of the support column. An opening is provided on the communication terminal around the limit plate, and a limit strip is provided on the support column, the limit strip being located between the groove and the protrusion.

[0015] Preferably, a limiting sleeve is sleeved around the periphery of the communication terminal, an insert block is provided on the inner side of the limiting sleeve, and a slot is provided on the communication terminal, with the insert block and the slot being adapted to each other.

[0016] Preferably, a sealing ring is provided on the periphery of the limiting sleeve.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] This utility model optimizes the structure by molding the terminal body, elastic element, and protrusion-groove interlocking structure in one piece, eliminating the need for subsequent electroplating and complex assembly, significantly reducing processing costs and enabling fully automated production. Structurally, it employs a hollow tubular design with elastic elements at both ends, forming a stable ring structure through protrusion-groove interlocking. The elastic element compresses the plug and charging gun, ensuring a tight connection and reliable contact, thus improving signal transmission stability. Simultaneously, the material is replaced with more cost-effective phosphor bronze or brass strips, and the pre-plating process eliminates the need for individual electroplating steps, simplifying the production process while maintaining conductivity and oxidation resistance, achieving both cost advantages and improved technical performance.

[0025] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0026] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0027] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0028] As attached Figure 1 To be continued Figure 4 As shown:

[0029] Example 1: This example provides an integrated stamped terminal for a DC socket, including a communication terminal 1. One side of the communication terminal 1 is provided with several protrusions 5, and the other side of the communication terminal 1 is provided with several grooves 4. The protrusions 5 and the grooves 4 are matched. The cross-section of the communication terminal 1 is arc-shaped. Both ends of the communication terminal 1 are provided with several elastic elements 2. The communication terminal 1 around the elastic elements 2 is provided with a dividing groove 3.

[0030] During production, the communication terminal 1 is integrally stamped from pre-plated phosphor bronze strip or pre-plated brass strip. During the stamping process, groove 4, protrusion 5, and dividing groove 3 are formed. The communication terminal 1 part at dividing groove 3 is bent to form elastic element 2. After stamping, the appearance is flat. Then, it is bent in a ring until protrusion 5 and groove 4 are engaged to form a hollow tubular communication terminal 1. When in use, the communication terminal 1 is inserted into the terminal slot in the DC socket. Then, the plug of the circuit board is inserted into one end of the hollow tubular communication terminal 1, and the communication interface of the charging gun is inserted into the other end of the hollow tubular communication terminal 1. The signal transmission path is charging connector → probe → PCB circuit board wiring → plug → communication terminal 1 → charging gun. The communication terminal 1 will use its own elasticity to squeeze the plug and charging gun after being connected to the plug and charging gun through the elastic elements 2 at both ends, ensuring connection stability and tight contact.

[0031] Specifically, elastic element 2 tilts inward.

[0032] This is used to generate a slanted pushing force on the elastic element 2 during the process of inserting the plug or charging gun into the communication terminal 1, so that it will not affect the insertion and removal of the plug or charging gun, and after being pushed away, the elastic element 2 swings back to the initial direction by its own elasticity, so that it always keeps in contact with the plug or charging gun.

[0033] Specifically, a second elastic element 108 is provided at the bottom of the communication terminal 1, and a second dividing groove 109 is provided on the communication terminal 1 around the second elastic element 108.

[0034] During the integral stamping process, a second dividing groove 109 is generated, and the communication terminal 1 at the second dividing groove 109 is bent to form an elastic element 108.

[0035] Specifically, elastic element 2 108 tilts outward.

[0036] When in use, the communication terminal 1 is inserted into the terminal slot in the socket. The terminal slot is provided with a through groove. During the insertion of the communication terminal 1, the terminal slot will generate a slanted pushing force on the elastic element, so that it will not affect the insertion of the communication terminal 1. When the elastic element 108 moves to the through groove, it will return to its original position due to the disappearance of resistance, thereby limiting the position of the communication terminal 1 and making it difficult to pull out.

[0037] Example 2: This example is basically the same as the previous example, except that a support column 102 is movably arranged inside the communication terminal 1. Both ends of the support column 102 are provided with limit plates 104. An opening 101 is provided on the communication terminal 1 around the limit plate 104. A limit strip 103 is provided on the support column 102. The limit strip 103 is located between the groove 4 and the protrusion 5.

[0038] Specifically, a limiting sleeve 105 is sleeved around the periphery of the communication terminal 1, and an insert block 106 is provided on the inner side of the limiting sleeve 105. A slot 107 is provided on the communication terminal 1, and the insert block 106 is adapted to the slot 107.

[0039] Specifically, a sealing ring 6 is provided on the outer periphery of the limiting sleeve 105.

[0040] As can be seen from the above, the support column 102 is used to support the communication terminal 1 inside, and the limiting sleeve 105 is used to limit the communication terminal 1 outside. The support column 102 and the limiting sleeve 105 are used to squeeze and limit the communication terminal 1 inside and outside, so that its shape is stable and maintains a tubular shape.

[0041] The limiting plate 104 will be inserted into the opening 101, and the limiting strip 103 will be inserted into the gap between the groove 4 and the protrusion 5 to limit the relative position between the support column 102 and the communication terminal 1.

[0042] The insert 106 is inserted into the slot 107 to limit the relative position of the communication terminal 1 and the limiting sleeve 105. When the communication terminal 1 is inserted into the terminal slot in the socket, the sealing ring 6 fills the gap between the terminal slot and the limiting sleeve 105 to improve the sealing performance.
