Description

Technical Field

[0001] This utility model relates to the field of connector technology, and in particular to a connector with a novel grounding structure. Background Technology

[0002] Connectors are devices that connect two active components to transmit current or signals, and are indispensable components in electronic devices. Connectors are widely used in various electronic devices, primarily serving the function of transmitting current or signals. With the rapid development of the connector industry in recent years, the market demand for connectors is also increasing, and the functional requirements for connectors are constantly improving. Currently, most connectors on the market use jumpers to connect the contacts and the housing for grounding. A jumper, also known as a bridging wire, is a wire used to connect two or more critical points on a circuit board. Its main function is to establish a temporary connection in electronic equipment to achieve a specific function or bypass faulty components. In various electrical connections, jumper grounding plays an important safety role.

[0003] However, jumper wires are usually thin or short, which may lead to high or unstable grounding resistance, especially in environments with changing soil moisture or corrosion, where grounding effectiveness will decrease. Furthermore, jumper wires are typically temporary or lightweight designs, and long-term use may cause breakage or poor contact; loose or oxidized connections can not only affect grounding performance but also pose safety hazards. Moreover, jumper grounding usually relies on manual installation, which is susceptible to human error and has lower reliability, requiring regular inspection and maintenance; otherwise, failures may go undetected.

[0004] Therefore, it is necessary to provide a connector with a novel grounding structure that is simple, robust, and can effectively ground. Utility Model Content

[0043] To explain the technical content and structural features of this utility model in detail, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0044] Please see Figures 1 to 6This utility model provides a connector 100 with a novel grounding structure, including a housing 10, a first component 1001, a second component 1002, and a grounding element 50. The housing 10 has a hollow cavity 101, with an inwardly recessed mounting groove 11 near its end. A limiting portion 12 protrudes from the center of the cavity 101. The first component 1001 includes a first cover 20 and a grounding terminal 42, which is installed within the first cover 20 to form the first component 1001. The first cover 20 is installed within the cavity 101 and abuts against the limiting portion 12, which restricts and positions the first cover 20. The second component 1002 includes a second cover 30 and connecting terminals 41, with multiple connecting terminals 41 installed within the second cover 30 to form the second component 1002. The second component 1002 is installed within the housing 10 and cooperates with the first component 1001 to form a connection structure 1003. The connecting terminal 41 is used for electrical connection with cables, etc., and the grounding terminal 42 is used for grounding connection. One end of the grounding member 50 is ring-shaped to form a mounting portion 51 that can be installed in the mounting groove 11, and the other end is bent inward to form a connecting end 52 with a hook. The mounting portion 51 is installed in the mounting groove 11 to reinforce the installation of the connecting structure 1003 in the housing 10, and the mounting portion 51 can contact the housing 10 with a larger area, thereby achieving a better grounding connection. The connecting end 52 is placed in the grounding terminal 42 and fixed by soldering, so that a conductive loop is formed between the housing 10 and the grounding terminal 42 through the grounding member 50, thus completing the grounding connection. In this embodiment, the housing 10, the terminal assembly 40, and the grounding member 50 can be made of metal material, and the first cover 20 and the second cover 30 can be made of plastic material.

[0045] With the above technical solution, the connector 100 of this utility model with a novel grounding structure includes a housing 10, a first component 1001, a second component 1002, and a grounding element 50. The housing 10 has a hollow cavity 101, and one end of the cavity 101 has an inwardly recessed mounting groove 11 for mounting the grounding element 50. A limiting portion 12 is also protruding from the middle of the cavity 101, limiting the first cover 20. The first component 1001 includes a first cover 20 and a grounding terminal 42, with the grounding terminal 42 installed inside the first cover 20, which is installed inside the cavity 101 and abuts against the limiting portion 12. The second component 1002 includes a second cover 30 and connecting terminals 41, with multiple connecting terminals 41 installed inside the second cover 30. The second component 1002 is installed inside the housing 10 and cooperates with the first component 1001 to form a connection structure 1003. One end of the grounding component 50 is ring-shaped to form a mounting portion 51 that can be installed in the mounting groove 11, and the other end is bent inward to form a connecting end 52 with a hook. The mounting portion 51 is installed in the mounting groove 11 to reinforce the installation of the connecting structure 1003 in the housing 10, making the overall structure more stable and reliable. The connecting end 52 is placed in the grounding terminal 42 and fixed by soldering to complete the grounding connection between the housing 10 and the grounding terminal 42. The connector 100 with the novel grounding structure of this utility model has a simple structure, is easy to connect and form, has a stable connection, a stable and reliable overall structure, and can effectively ground with a significant grounding effect.

[0046] Please see Figure 2 , Figure 3 and Figure 13 In some optional embodiments, one end of the grounding terminal 42 is provided with an inwardly recessed groove 421, and one side of the groove 421 has an opening 422 for the connecting end 52 to extend into the groove 421. The groove 421 facilitates the connecting end 52 to extend into the groove 421 and cooperate with the grounding terminal 42. On the other hand, one end of each connecting terminal 41 is provided with a connecting groove 411 for connecting to a cable or other connector.

[0047] Please see Figure 11 and Figure 12In some optional embodiments, a plurality of mounting holes 31 are provided through the second cover 30 for the connection terminal 41 to pass through and be installed. A plurality of gripper assemblies 32 are protruding from the side of the second cover 30 that mates with the first cover 20. The gripper assemblies 32 are used to reinforce the installation of the connection terminal 52 within the second cover 30. Specifically, each gripper assembly 32 includes a plurality of gripper pieces 321, which form an inner cavity 320 communicating with the mounting holes 31. The inner cavity 320 allows each gripper piece 321 to move elastically within a preset range. Since the connection terminal 41 passes through the inner cavity 320 between the gripper pieces 321, the gripper pieces 321 move elastically outward. The elastically deformed gripper pieces 321 always have a tendency to return to their original position, thus clamping the connection terminal 41 in the middle, resulting in a stable and reliable structure.

[0048] Please see Figure 2 , Figure 3 and Figures 11 to 13 In some optional embodiments, the connecting terminal 41 includes a first stepped portion 412 and a second stepped portion 413 protruding from its periphery, with an inwardly recessed annular groove 414 formed between the first stepped portion 412 and the second stepped portion 413. The connecting terminal 41 is installed in the mounting hole 31 and passes through the gripper assembly 32. Multiple gripper pieces 321 elastically wrap around the connecting terminal 41 and are located at the annular groove 414. The first stepped portion 412 and the second stepped portion 413 limit the gripper assembly 32 from both ends to strengthen the fit between the connecting terminal 41 and the second cover 30. The end of the gripper piece 321 away from the mating protrusion 34 abuts against the second stepped portion 413, making the overall structure stable and reliable.

[0049] Please see Figure 3 and Figures 8 to 12 In some optional embodiments, a first stepped hole 21 is formed through the first cover 20, and a first receiving groove 211 and a second receiving groove 212 are formed within the first stepped hole 21. The first receiving groove 211 is used to receive the gripper assembly 32, and the second receiving groove 212 is used to receive the second stepped portion 413. The second cover 30 is connected to the first cover 20 so that the gripper assembly 32 is located within the first receiving groove 211 in the first stepped hole 21, and the first receiving groove 211 can limit the gripper assembly 32 in the circumferential direction. The gripper assembly 32 is located within the annular groove 414 between the first stepped portion 412 and the second stepped portion 413, so that the gripper assembly 32 is restricted in both the vertical and circumferential directions, preventing it from moving freely, and the overall structure is stable and reliable. Simultaneously, when the first cover 20 and the second cover 30 are assembled, the mounting hole 31, the inner cavity 320, and the first stepped hole 21 form a first mounting assembly 102 for mounting and fixing the connection terminal 41.

[0050] Please see Figure 1 , Figure 2 , Figure 6 and Figure 12 In some optional embodiments, a mating protrusion 34 is provided at one end of the second cover 30, and multiple mounting holes 31 are formed within the mating protrusion 34. A through hole 33 for mounting the grounding terminal 42 is located outside the mating protrusion 34, so that the connecting end 52 of the grounding member 50 can mate with the groove 421 of the grounding terminal 42. The mating protrusion 34 mates with one end of the housing 10 to form a first mating end for connection, and there is a gap between the mating protrusion 34 and the housing 10 to allow for insertion with other connectors. On the other hand, the other end of the housing 10 is provided with a threaded portion 13 to form a second mating end for connection, allowing for threaded connection with other electrical structures. In the second mating end, the length of the grounding terminal 42 is longer than the length of the connecting terminal 41, so that effective grounding protection can be formed after connection.

[0051] Please see Figure 3 , Figures 9 to 12 In some optional embodiments, a second stepped hole 22 is formed in the first cover 20, and a through hole 33 is formed in the second cover 30. Specifically, the second cover 30 is connected to the first cover 20 so that the second stepped hole 22 and the through hole 33 form a second mounting assembly 103 for mounting the grounding terminal 42. During installation, the grounding terminal 42 first mates with the first cover 20 and then is installed inside the housing 10. When the second cover 30, which has multiple connecting terminals 41, is installed inside the housing 10, it mates with the first cover 20, such that the connecting terminals 41 and the grounding terminal 42 are simultaneously located inside the first cover 20 and the second cover 30, forming a first mounting assembly 102 for accommodating and fixing the connecting terminals 41, and a second mounting assembly 103 for accommodating and fixing the grounding terminal 42.

[0052] Please see Figure 2 , Figure 3 and Figure 13 In some optional embodiments, a limiting block 423 is protruding from the grounding terminal 42, and the limiting block 423 has a flat positioning surface 424. On the other hand, a limiting groove 221 that mates with the limiting block 423 is provided within the second stepped hole 22, and a positioning part 222 that mates with the positioning surface 424 is provided within the limiting groove 221. When the grounding terminal 42 is installed in the second stepped hole 22, the limiting block 423 is placed within the limiting groove 221, and the positioning surface 424 mates with the positioning part 222. The mate between the positioning surface 424 and the positioning part 222 ensures a fixed installation angle for the grounding terminal 42, thereby allowing the opening 422 on the groove 421 to better mate with the grounding member 50.

[0053] Please see Figures 8 to 12In some optional embodiments, a guide block 14 is provided protruding along the length of the cavity 101, a first guide groove 23 is provided on the first cover 20, and a second guide groove 35 is provided on the second cover 30. During installation, both the first guide groove 23 and the second guide groove 35 cooperate with the guide block 14 so that the first cover 20 and the second cover 30 are installed in the cavity 101 at a preset angle. The guide block 14 can play a foolproof guiding role, so that the first cover 20 and the second cover 30 can be better installed in the housing 10.

[0054] Please see Figure 7 , Figure 8 and Figure 10 In some optional embodiments, one end of the first cover 20 is provided with a mounting limiting surface 24, which is stepped. The first cover 20 is installed in the cavity 101 so that the mounting limiting surface 24 abuts against the limiting part 12. The cooperation between the mounting limiting surface 24 and the limiting part 12 ensures a stable and reliable fit at that end.

The grounding terminal 42 is installed inside the first cover 20 to form a first assembly 1001, and the first cover 20 is installed inside the cavity 101 and abuts against the limiting portion 12. Alternatively, the first cover 20 can be installed inside the housing 10 first, and then the grounding terminal 42 can be installed inside the first cover 20. Multiple connecting terminals 41 are installed within the second cover 30 to form a second component 1002. The second component 1002 is installed within the cavity 101, and the first component 1001 and the second component 1002 are interconnected to form a connecting structure 1003. The first cover 20 and the second cover 30 form a cover structure within the cavity 101.
