Description

[0002] In electric vehicles, plug-in connectors are often used to charge the power battery, or two electrically connected devices are electrically connected through plug-in connectors.

[0003] The plug-in connector includes an insulating block, connector terminals, and a shielding shell. The insulating block has multiple holes, and the connector terminals have multiple terminals, each corresponding to one of the holes. Each connector terminal is fixedly installed in its corresponding hole, allowing the cable conductor to pass through the hole and electrically connect to the connector terminal. The conductor has wire terminals that are electrically connected to the connector terminal. Specifically, each connector terminal is electrically connected to one wire. The shielding shell is fitted over the insulating block, covering the connection point between the connector terminal and the wire. The shielding shell is typically made of metal. After the shielding shell is fitted over the insulating block, there is a small gap between the shielding shell and the wire terminal. However, if the conductive terminal has crimp burrs, especially high burrs, the conductive terminal can easily contact the shielding shell, potentially causing a short circuit and reducing the safety and reliability of the plug-in connector.

[0004] Therefore, there is an urgent need for a plug-in connector and connection assembly to solve the above problems. Summary of the Invention

[0042] This embodiment provides a plug-in connector with high safety and reliability. The plug-in connector provided in this embodiment can be used in vehicles, specifically for connecting high-speed wiring harnesses. In some embodiments, the plug-in connector in this embodiment is an HSD high-speed connector.

[0043] like Figures 1 to 4 As shown, the plug-in connector includes an insulating base 1, an insulating plug 2, a connector terminal 3, and an outer conductor 4.

[0044] The insulating base 1 has a terminal hole 11 and a groove 12 communicating with the terminal hole 11. In this embodiment, the terminal hole 11 and the groove 12 are arranged sequentially along the length of the insulating base 1. A connector terminal 3 is installed in the terminal hole 11. In some embodiments, the connector terminal 3 is fixedly installed in the terminal hole 11. In this embodiment, one end of the connector terminal 3 can extend into the groove 12, or the connector terminal 3 may not extend into the groove 12. This embodiment does not limit this. When one end of the connector terminal 3 extends into the groove 12, the groove 12 is also used to accommodate the wire terminal of the cable for connection with the plug-in connector, that is, at least a portion of the wire terminal is located in the groove 12 and electrically connected to the connector terminal 3 in the groove 12. When one end of the connector terminal 3 does not extend into the groove 12, the groove 12 is used to support the wire terminal. The wire terminal passes through the groove 12 and extends into the terminal hole 11, and is electrically connected to the connector terminal 3. The connector terminal 3 in this embodiment can be a structure from the prior art, and this embodiment does not limit this.

[0045] The insulating plug 2 is fixedly mounted on the insulating base 1, and the insulating plug 2 and the insulating base 1 are two independent structures. In this embodiment, the fixed mounting means that the insulating plug 2 will not shift or rotate after being mounted on the insulating base 1. In some embodiments, the insulating plug 2 is detachably connected to the insulating base 1, such as by snap-fit ​​or plug-in connection; this embodiment does not limit this. The outer conductor 4 is sleeved over at least a portion of the insulating base 1 and at least a portion of the insulating plug 2. In this embodiment, the outer conductor 4 is sleeved over a portion of the insulating base 1 and over the entire insulating plug 2. The insulating plug 2 is used to separate the outer conductor 4 from the conductor located in the groove 12 to prevent contact between the conductor in the groove 12 and the outer conductor 4. In this embodiment, the conductor in the groove 12 can be a wire terminal. When one end of the connector terminal 3 is located in the groove 12, the conductor in the groove 12 can also be a wire terminal and a connector terminal 3. In some embodiments, the outer conductor 4 can be a shielding ring.

[0046] When assembling the plug-in connector provided in this embodiment, the wire terminal is first electrically connected to the connector terminal 3. Then, the insulating plug 2 is installed on the insulating base 1 so that the insulating plug 2 can cover the wire terminal located in the groove 12 or cover the wire terminal and the connector terminal 3, so that there are no exposed parts of the wire terminal and the connector terminal 3. After that, the outer conductor 4 is sleeved on the insulating base 1 and the insulating plug 2.

[0047] The plug-in connector provided in this embodiment, by installing an insulating plug 2 on the insulating base 1, and the insulating plug 2 is used to separate the outer conductor 4 from the conductor located in the groove 12, so that when there are crimping burrs on the conductor in the groove 12, the crimping burrs can be covered or blocked by the insulating plug 2, thereby preventing the conductor from contacting the outer conductor 4 through the crimping burrs, avoiding short circuit between the conductor and the outer conductor 4, and improving the safety and reliability of the plug-in connector.

[0048] Optionally, such as Figure 3 and Figure 4 As shown, at least part of the insulating plug 2 is inserted into the groove 12, which facilitates the installation and removal of the insulating plug 2, and also avoids the insulating plug 2 occupying too much installation space, thus contributing to the miniaturization of the plug-in connector. Furthermore, please refer to... Figure 3 The portion of the insulating plug 2 inserted into the groove 12 contacts the groove wall of the groove 12. That is, the portion of the insulating plug 2 inserted into the groove 12 can seal the groove 12 in the width direction, preventing the conductor from being exposed through the gap between the insulating plug 2 and the insulating seat 1, and further improving the reliability of separating the conductor from the outer conductor 4. In other embodiments, the portion of the insulating plug 2 inserted into the groove 12 can also be spaced apart from the groove wall of the groove 12.

[0049] In this embodiment, the plug-in connector can be a connector with one connector terminal 3, or as... Figure 4 and Figure 5 As shown, the plug-in connector has multiple connector terminals 3 for connecting to cables containing multiple wires. Specifically, multiple terminal holes 11, recesses 12, and connector terminals 3 are provided. The multiple terminal holes 11 are independent of each other, the multiple recesses 12 are independent of each other, and the multiple terminal holes 11 and multiple recesses 12 are connected in a one-to-one correspondence, that is, the multiple terminal holes 11 and multiple recesses 12 are connected one-to-one, and each terminal hole 11 is connected to its corresponding recess 12. The multiple connector terminals 3 are connected one-to-one with the multiple terminal holes 11, and each connector terminal 3 is installed in its corresponding terminal hole 11, realizing the assembly of multiple connector terminals 3. Furthermore, the insulating plug 2 includes multiple blocking portions 21, which correspond one-to-one with the multiple recesses 12, and each blocking portion 21 is used to separate the outer conductor 4 from the conductor located in the recess 12 corresponding to that blocking portion 21, so that the conductor in each recess 12 will not be short-circuited to the outer conductor 4. It should be noted that the blocking portion 21 is inserted into its corresponding recess 12, and in some embodiments, such as... Figure 12 As shown, the barrier portion 21 is located only at the opening of the groove 12 and does not extend to the bottom of the groove 12, so that the groove 12 has a large space to accommodate the conductor, and the conductor in the groove 12 does not contact the barrier portion 21. In some other embodiments, the barrier portion 21 can fill the area of ​​the groove 12 where the conductor is removed, and the conductor in the groove 12 contacts the barrier portion 21, so that the barrier portion 21 can not only separate the conductor from the outer conductor 4, but also limit the conductor, reduce the probability of conductor shaking, and thus reduce the probability of the conductor separating from the connector terminal 3. In this embodiment, there are four terminal holes 11, four grooves 12, four connector terminals 3, and four barrier portions 21.

[0050] In some embodiments, the insulating base 1 is columnar, and a plurality of terminal holes 11 are evenly and spaced apart on the insulating base 1 around its axis. See also... Figure 4 Multiple grooves 12 are evenly and spaced around the axis of the insulating base 1, and the cross-section of the portion of the insulating base 1 with the grooves 12 is cross-shaped. This arrangement of the terminal holes 11 and grooves 12 allows for a smaller footprint, thus enabling a smaller cross-sectional area for the insertion connector.

[0051] Please continue reading Figure 4The insulating plug 2 also includes a main body 22, with multiple blocking portions 21 connected to one end of the main body 22, and the multiple blocking portions 21 located at the same end of the main body 22. The main body 22 is columnar; in some embodiments, the main body 22 is hollow columnar to reduce material consumption without excessively increasing the weight of the plug-in connector, thus facilitating the lightweighting of the plug-in connector. The multiple blocking portions 21 are evenly and spaced around the axis of the main body 22 to mate with the multiple grooves 12. It should be noted that the axis of the insulating plug 2 is parallel to or coincides with the axis of the insulating base 1.

[0052] Furthermore, such as Figure 6 As shown, one end of the insulating base 1 contacts one end of the main body 22. Specifically, one end of the insulating base 1 with the groove 12 contacts one end of the main body 22 with the blocking part 21, for positioning and limiting the installation of the insulating plug 2. Furthermore, as... Figure 4 As shown, the insulating base 1 has a limiting end block 13 in the middle, and the end of the blocking portion 21 away from the main body 22 contacts the limiting end block 13 to provide the installation limit for the insulating plug 2. When installing the insulating plug 2, if one end of the main body 22 contacts the insulating base 1 and the blocking portion 21 contacts the limiting end block 12, it indicates that the insulating plug 2 is installed in place and there is no need to move the insulating plug 2 further. It should be noted that one section of the terminal hole 11 is formed on the limiting end block 13.

[0053] Optionally, such as Figure 3 and Figure 8 As shown, the insulating plug 2 also includes a positioning strip 23, which is connected to one end of the main body 22. Specifically, the positioning strip 23 is connected to one end of the main body 22 that connects to the blocking part 21. Figure 7 or Figure 12 As shown, the insulating base 1 has a positioning groove 14 that mates with the positioning strip 23, and the extending direction of the positioning groove 14 is parallel to the extending direction of the recess 12. The positioning strip 23 is inserted into the positioning groove 14 to enable alignment and positioning during the initial installation of the insulating plug 2, facilitating the installation of the insulating plug 2 and increasing the efficiency of installing the insulating plug 2. This, in turn, increases the assembly efficiency of the plug-in connector. Furthermore, the engagement between the positioning strip 23 and the positioning groove 14 also guides the movement of the insulating plug 2. The length of the positioning strip 23 can be set according to actual needs. In some embodiments, the length of the positioning strip 23 is equal to the length of the blocking portion 21.

[0054] In this embodiment, of the insulating base 1 and the insulating plug 2, one has a circumferential limiting block 15, and the other has a circumferential limiting groove or circumferential limiting opening 24. The circumferential limiting block 15 is placed in the circumferential limiting groove or circumferential limiting opening 24 so that the insulating base 1 limits the insulating plug 2 in its circumference, thereby preventing the insulating plug 2 from moving in the circumferential direction of the insulating base 1. In this embodiment, the insulating base 1 is provided with a circumferential limiting block 15, and the insulating plug 2 is provided with a circumferential limiting opening 24. When installing the insulating plug 2, the circumferential limiting block 15 is inserted into the circumferential limiting opening 24, so that the insulating plug 2 can be inserted into the insulating base 1 with the circumferential limiting block 15 as a guide. It should be noted that the circumferential limiting slot 24 on the insulating plug 2 consists of two parts: one part is formed on the main body 22, and the other part is formed by two adjacent blocking parts 21. That is, the circumferential limiting slot 24 penetrates the insulating plug 2 along its axial direction, so that when installing the insulating plug 2, the cable can be first inserted into the insulating plug 2 through the circumferential limiting slot 24, and then the insulating plug 2 can be pushed to move to connect the insulating plug 2 and the insulating seat 1. When the insulating plug 2 is provided with a circumferential limiting groove, the insulating plug 2 does not have an opening penetrating both ends of its axial direction. In this case, the insulating plug 2 can be placed on the cable before connecting the wire terminal and the connector terminal 3. After the wire terminal and the connector terminal 3 are connected, the insulating plug 2 can be pushed closer to the insulating seat 1 to connect the insulating plug 2 and the insulating seat 1.

[0055] It should be noted that in this embodiment, the insulating plug 2 is an integrally molded structure, and the material can be flexible materials such as rubber and silicone. This embodiment does not limit this.

[0056] Optionally, such as Figure 12 As shown, the outer surface of the insulating plug 2 is flush with the outer surface of the insulating base 1, so that the installation of the insulating plug 2 does not increase the radial dimension of the structure on which the outer conductor 4 is fitted. This allows the original outer conductor 4 to be used without the need to remanufacture it, and the radial dimension of the plug-in connector is not increased, which is beneficial for the miniaturization of the plug-in connector. Additionally, please refer to... Figure 12 In this embodiment, there is a gap D between the insulating plug 2 and the outer conductor 4 to form double protection to prevent the outer conductor 4 from contacting the conductor in the groove 12.

[0057] In this embodiment, as Figure 5 and Figure 6 As shown, the insulating base 1 has a positioning hole 16, as Figure 14As shown, the inner wall of the outer conductor 4 has a positioning protrusion 41, which can be engaged in the positioning hole 16 to achieve positioning and installation of the outer conductor 4 and the insulating base 1. In some embodiments, the positioning hole 16 is a circular hole, and the positioning protrusion 41 is hemispherical, so that the outer conductor 4 can be sleeved on part of the insulating base 1. In some embodiments, the inner wall of the outer conductor 4 also has other positioning structures, and the insulating base 1 also has corresponding structures for auxiliary positioning to ensure that the outer conductor 4 can be installed in place.

[0058] The structure of the insulating base 1 can be varied, for example, such as Figure 7 As shown, the insulating base 1 includes a base body 17 and a guide shell 18 sleeved and installed on one end of the base body 17. One end of the base body 17 is a connecting end, and the other end is a terminal end. A groove 12 is formed at the connecting end, and the terminal end has a groove structure. The guide shell 18 is sleeved and installed at the terminal end, and the guide shell 18 has a covering structure, so that the guide shell 18 and the base body 17 cooperate to form a terminal hole 11. A limiting end block 13, a positioning groove 14, and a circumferential limiting block 15 are respectively provided on the base body 17, and a positioning hole 16 is provided on the guide shell 18.

[0059] Optionally, the inner wall of the outer conductor 4 also has an axial limiting structure (not shown), which is used to abut against the end of the main body 22 where the blocking part 21 is provided, so as to cooperate with the insulating seat 1 to axially limit the insulating plug 2 to prevent the insulating plug 2 from moving.

[0060] This embodiment also provides a connection component, which includes a cable and the aforementioned plug-in connector.

[0061] The cable has wire terminals that are electrically connected to connector terminals 3, and at least some of the wire terminals are located in the groove 12. The insulating plug 2 is used to separate the outer conductor 4 from the wire terminals located in the groove 12 to prevent the outer conductor 4 from contacting the wire terminals.

[0062] The connection assembly provided in this embodiment isolates the outer conductor 4 and the wire terminals through the insulating plug 2, thereby avoiding short circuits between the outer conductor 4 and the wire terminals and providing high safety and reliability.

[0063] Optionally, such as Figure 5 As shown, the connecting component is also covered by a housing 10, which is used to protect the connecting component, such as meeting the waterproof and dustproof requirements of the connecting component.

[0064] Note that the above description is merely a preferred embodiment of the present invention and the technical principles employed. Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and various obvious changes, readjustments, and substitutions can be made without departing from the scope of protection of the present invention. Therefore, although the present invention has been described in detail through the above embodiments, the present invention is not limited to the above embodiments, and may include many other equivalent embodiments without departing from the concept of the present invention, the scope of which is determined by the scope of the appended claims.
