Description

Technical Field

[0001] The present invention relates to the technical field of connectors, and in particular to a connector with a novel grounding structure and an assembly molding process thereof. Background Art

[0002] Connectors are devices that connect two active components, used to transmit current or signals, and are indispensable components in electronic devices. Connectors are widely used in a variety of electronic devices, primarily for transmitting current or signals. With the rapid development of the connector industry in recent years, market demand for connectors has also been growing, and the functional requirements for connectors are also continuously improving. Currently, most connectors on the market use jumpers to connect the contacts to the housing for grounding. Jumpers, also known as jumper wires, are wires used to connect two or more key points on a circuit board. Their primary function is to establish temporary connections in electronic devices to achieve specific functions or bypass faulty components. Jumper grounding plays a vital safety role in various electrical connections.

[0003] However, jumper cables are typically thin or short, which can lead to high or unstable grounding resistance, especially in environments with fluctuating soil moisture or corrosive conditions, where the grounding effect can be reduced. Furthermore, jumper cables are typically designed to be temporary or lightweight, and long-term use can lead to breakage or poor contact. If the connection points become loose or oxidized, this not only affects grounding performance but can also pose a safety hazard. Furthermore, jumper grounding often relies on manual installation, which can lead to human error and low reliability. Regular inspection and maintenance are required, otherwise failure may go undetected.

The connecting end 52 is placed in the grounding terminal 42 and fixed by soldering to form a conductive loop between the shell 10 and the grounding terminal 42 through the grounding member 50 to complete the grounding connection. In this embodiment, the shell 10, the terminal assembly 40 and the grounding member 50 can be made of metal material, and the first cover body 20 and the second cover body 30 can be made of plastic material.

[0037] After adopting the above technical solution, the connector 100 with a new grounding structure of the present invention includes a shell 10, a first cover 20, a second cover 30, a terminal assembly 40 and a grounding member 50. The shell 10 is provided with a hollow cavity 101, and one end of the cavity 101 is provided with an inwardly recessed mounting groove 11, and the mounting groove 11 is used to install the grounding member 50. A limiting portion 12 is also protrudingly provided in the middle of the cavity 101, and the limiting portion 12 is used to limit the first cover 20. The first cover 20 is installed in the cavity 101 and abuts against the limiting portion 12.

The terminal assembly 40 includes a connecting terminal 41 and a grounding terminal 42. The connecting terminal 41 is installed in the first installation assembly 102, and the grounding terminal 42 is installed in the second installation assembly 103. 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 inwardly into the ring 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 cover structure in the shell 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 shell 10 and the grounding terminal 42. The connector 100 with a new grounding structure of the present invention has a simple structure, convenient connection and forming, and a stable connection. The overall structure is stable and reliable, and can be effectively grounded with an obvious grounding effect.

[0038] See also Figure 2 、 Figure 3 and Figure 11 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 is provided with an opening 422 for facilitating the insertion of the connecting terminal 52 into the groove 421. The groove 421 facilitates the insertion of the connecting terminal 52 into the groove 421 for mating with the grounding terminal 42. Furthermore, one end of each connecting terminal 41 is provided with a connection slot 411 for connecting to a cable or other connector.

[0039] See also Figure 9 and Figure 10In some optional embodiments, a plurality of mounting holes 31 are provided through the second cover 30, and the mounting holes 31 are used for the connection terminals 41 to pass through for installation. A plurality of groups of clamping jaw assemblies 32 are protrudingly provided on a side of the second cover 30 that cooperates with the first cover 20, and the clamping jaw assemblies 32 are used to reinforce the installation of the connection end 52 in the second cover 30. Specifically, each group of clamping jaw assemblies 32 includes a plurality of clamping jaw members 321, and the plurality of clamping jaw members 321 are arranged to form an inner cavity 320 connected to the mounting hole 31, and the inner cavity 320 enables each clamping jaw member 321 to elastically move within a preset range. Since the connection terminal 41 passes through the inner cavity 320 in the middle of the plurality of clamping jaw members 321, the plurality of clamping jaw members 321 will elastically move outward, and the elastically deformed clamping jaw members 321 always have a tendency to reset, thereby clamping the middle connection terminal 41, and the structure is stable and reliable.

[0040] See also Figure 2 、 Figure 3 and Figures 9 to 11 In some optional embodiments, the connection terminal 41 includes a first step portion 412 and a second step portion 413 protruding from the peripheral side, and an inwardly recessed annular groove 414 is formed between the first step portion 412 and the second step portion 413. The connection terminal 41 is installed in the mounting hole 31 and passes through the clamping jaw assembly 32. A plurality of clamping jaws 321 elastically wrap around the connection terminal 41 and are located in the annular groove 414. The first step portion 412 and the second step portion 413 limit the clamping jaw assembly 32 from both ends to strengthen the fit between the connection terminal 41 and the second cover 30. The end of the clamping jaw 321 away from the mating protrusion 34 abuts against the second step portion 413, making the overall structure stable and secure.

[0041] See also Figure 3 and Figures 6 to 10 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 accommodate the clamping jaw assembly 32, and the second receiving groove 212 is used to accommodate the second stepped portion 413. The second cover 30 is connected to the first cover 20 so that the clamping jaw assembly 32 is located within the first receiving groove 211 within the first stepped hole 21. The first receiving groove 211 can circumferentially limit the position of the clamping jaw assembly 32. The clamping jaw assembly 32 is located within the annular groove 414 between the first stepped portion 412 and the second stepped portion 413, thereby restricting the clamping jaw assembly 32 in both the vertical and circumferential directions, preventing it from moving freely, and ensuring a stable and secure overall structure. Furthermore, 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 connecting terminal 41.

[0042] See also Figure 1 、 Figure 2 、 Figure 6 and Figure 10 In some optional embodiments, a mating protrusion 34 is protrudingly provided at one end of the second cover body 30, and a plurality of mounting holes 31 are provided in the mating protrusion 34. The 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 be mated with the groove 421 of the grounding terminal 42. The mating protrusion 34 is mated 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 facilitate plug-in mating with other connectors. On the other hand, a threaded portion 13 is provided at the other end of the housing 10 to form a second mating end for connection, so that it can be threadedly connected to other electrical structures. The length of the grounding terminal 42 in the second mating end is longer than the length of the connecting terminal 41, so that grounding protection can be effectively formed after connection.

[0043] See also Figure 3 and Figures 6 to 10 In some optional embodiments, a second stepped hole 22 is defined in the first cover 20, and a through hole 33 is defined 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 is first mated with the first cover 20 and then installed within the housing 10. When the second cover 30, which is mounted with a plurality of connection terminals 41, is installed within the housing 10, it is mated with the first cover 20 so that the connection terminals 41 and the grounding terminals 42 are simultaneously located within the first cover 20 and the second cover 30, forming a first mounting assembly 102 for accommodating and fixing the connection terminals 41, and a second mounting assembly 103 for accommodating and fixing the grounding terminals 42.

[0044] See also Figure 2 、 Figure 3 and Figure 11 In some optional embodiments, a limit block 423 is protruding from the ground terminal 42, and a flat positioning surface 424 is provided on the limit block 423. Furthermore, a limit groove 221 is provided within the second stepped hole 22 to cooperate with the limit block 423, and a positioning portion 222 is provided within the limit groove 221 to cooperate with the positioning surface 424. When the ground terminal 42 is installed in the second stepped hole 22, the limit block 423 is placed within the limit groove 221, and the positioning surface 424 cooperates with the positioning portion 222. The cooperation between the positioning surface 424 and the positioning portion 222 ensures that the installation angle of the ground terminal 42 is constant, thereby allowing the opening 422 in the groove 421 to better cooperate with the grounding member 50.

[0045] See also Figures 5 to 10In 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, the first guide groove 23 and the second guide groove 35 cooperate with the guide block 14 to ensure that the first cover 20 and the second cover 30 are installed at a predetermined angle within the cavity 101. The guide block 14 can serve as a foolproof guide, allowing the first cover 20 and the second cover 30 to be more easily installed within the housing 10.

[0046] See also Figures 1 to 3 and Figure 13 and Figure 14 The present invention also provides an assembly molding process for assembling and molding the connector 100 with the novel grounding structure, comprising the following steps: S1, such as Figure 13 As shown, the connecting terminal 41 is installed in the second cover body 30 to form the first component 1001, and the multiple connecting terminals 41 respectively pass through the corresponding mounting holes 31 and the inner cavity 320 of the corresponding clamping jaw assembly 32, and the clamping jaw member 321 of the clamping jaw assembly 32 is clamped in the annular groove 414 between the first step portion 412 and the second step portion 413 to ensure the structure of the first component 1001 is stable.

[0047] like Figure 14 As shown, the grounding terminal 42 is installed in the second stepped hole 22 of the first cover 20, and the stopper 423 of the grounding terminal 42 is placed in the stopper groove 221 of the second stepped hole 22. The positioning surface 424 cooperates with the positioning portion 222 to ensure that the grounding terminal 42 is fixed in position within the second stepped hole 22, thereby better cooperating with the grounding member 50. Meanwhile, the first cover 20 is installed in the housing 10, and the installation stopper surface 24 of the first cover 20 abuts against the stopper 12 in the housing 10, thereby limiting the position of the second cover 30 from the bottom of the first cover 20. The first cover 20, the housing 10, and the grounding terminal 42 cooperate to form the second assembly 1002. The first assembly 1001 and the second assembly 1002 can be assembled separately and simultaneously. Specifically, the grounding terminal 42 can be installed in the first cover 20 first, and then the second cover 30 with the grounding terminal 42 installed can be installed in the housing 10. Alternatively, the first cover 20 is first installed in the housing 10, and then the ground terminal 42 is installed in the first cover 20. The specific installation sequence can be set according to actual installation needs.

[0048] S2, install the first component 1001 in the second component 1002 to form a connection structure, and make the first cover body 20 and the second cover body 30 form a cover structure in the shell 10, so that the installation of the connecting terminal 41 and the grounding terminal 42 in the first cover body 20 and the second cover body 30 is more stable. Among them, the clamping jaw assembly 32 of the second cover body 30 is installed in the first step hole 21 of the first cover body 20 to limit the movement of the clamping jaw 321 from the circumferential direction, so that the clamping jaw assembly 32 can be better located in the annular groove 414, and the overall structure is more stable. The mounting hole 31, the clamping jaw assembly 32 and the first step hole 21 form a first mounting assembly 102 for accommodating the connecting terminal 41. On the other hand, the through hole 33 on the second cover body 30 is connected to the second step hole 22 on the first cover body 20, forming a second mounting assembly 103 for accommodating the fixed grounding terminal 42.

[0049] S3, such as Figure 1 and Figure 3 As shown, the mounting portion 51 of the grounding member 50 is pressed into the mounting groove 11 to limit the cover structure in the radial direction of the housing 10. The angle of the grounding member 50 is adjusted so that the connecting end 52 of the grounding member 50 is located inside the grounding terminal 42. The grounding terminal 42 and the connecting end 52 of the grounding member 50 are then fixed by soldering, so that the housing 10, the grounding terminal 42 and the grounding member 50 form a conductive loop, completing the formation of the connector 100 with a new grounding structure. The installation of the grounding member 50 makes the installation of the cover structure in the housing 10 more stable and secure; at the same time, it makes the grounding terminal 42 more firmly placed in the second mounting assembly 103; and also realizes the grounding conductivity of the housing 10, the grounding terminal 42 and the grounding member 50.

[0050] By adopting the above technical solutions, the assembly molding process of the present invention can effectively mold the connector 100 with a novel grounding structure, making the overall structure of the connector 100 with the novel grounding structure stable and having a good grounding effect. The grounding member 50 not only serves as a grounding device, but also reinforces the installation of the first cover 20 and the second cover 30 within the housing 10. The assembly is convenient, the assembly effect is good, and the grounding effect is good, making it suitable for widespread use.

The shell 10 is provided with a hollow cavity 101, and one end of the cavity 101 is provided with an inwardly recessed mounting groove 11, and the mounting groove 11 is used to install the grounding member 50. A limiting portion 12 is also protruding from the middle of the cavity 101, and the limiting portion 12 is used to limit the first cover 20. The first cover 20 is installed in the cavity 101 and abuts against the limiting portion 12, and the grounding terminal 42 is installed in the first cover 20.
