[0044] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal encapsulation of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0045] The following is in conjunction with the appendix Figure 1-3 This invention describes the connector housing according to an embodiment of the present invention.

[0046] The connector of this utility model embodiment includes a housing 1 and a rubber core 2 disposed inside the housing 1.

[0047] like Figure 1-3 As shown, the housing 1 can be a metal housing 1, and the rubber core 2 disposed inside the housing 1 is integrally molded from insulating material.

[0048] It is understood that when processing the connector of this utility model embodiment, the housing 1 can be obtained by die casting of the module first, and then the core 2 can be obtained by injection molding directly in the housing 1, so as to obtain the main structure of the connector of this application embodiment.

[0049] Compared to connectors in related technologies, the connector core 2 of this utility model embodiment is an integrally molded structure, requiring only one set of molds to manufacture the core 2, which reduces processing costs and also reduces the number of connector components, making it easier to process and manufacture.

[0050] like Figure 1-3As shown, the core 2 has a plug channel 201 and a socket channel 202. The plug channel 201 and the socket channel 202 are respectively connected to the outside of the housing 1 and are interconnected. A connection position 203 is provided at the connection between the plug channel 201 and the socket channel 202. The plug channel 201 is used for the insertion of the plug terminal 3, and the socket channel 202 is used for the insertion of the socket terminal 4. One end of the plug terminal 3 and one end of the socket terminal 4 are connected at the connection position 203.

[0051] It is understandable that when injection molding the core 2, a nut can be pre-embedded in the connection position 203 so that one end of the plug terminal 3 and one end of the socket terminal 4 located in the connection position 203 can be connected by bolts.

[0052] In summary, by making the core 2 inside the housing 1 an integrally molded structure, the connector housing of this utility model embodiment can reduce the complexity of the connector housing structure and facilitate processing and manufacturing.

[0053] Therefore, the connector housing of this utility model embodiment has the characteristics of simple structure and convenient processing.

[0054] In some embodiments, such as Figure 1-3 As shown, the housing 1 has a first channel 101 communicating with the socket channel 202 and a first opening 102 communicating with the first channel 101. That is to say, the core 2 does not occupy the entire space inside the housing 1. The area inside the housing 1 corresponding to the socket channel 202 of the core 2 is provided with a first channel 101 communicating with the socket channel 202. The housing 1 is also provided with a first opening 102 corresponding to the first channel 101 communicating with the outside of the housing 1.

[0055] Similarly, the housing 1 also has a second channel 103 connected to the plug channel 201 and a second port 104 connected to the second channel 103. The area inside the housing 1 corresponding to the core 2 is provided with the second channel 103 connected to the plug channel 201. The housing 1 is also provided with a second port 104 corresponding to the second channel 103, connecting the first channel 101 and the outside of the housing 1.

[0056] Furthermore, such as Figure 1-3 As shown, an annular groove 5 is provided at the second opening 104 of the housing 1 along the outer edge of the second opening 104, and a sealing ring 6 is embedded in the annular groove 5.

[0057] The connector of this utility model has an annular groove 5 along the outer edge of the second opening 104 at the housing 1, and a sealing ring 6 is embedded in the annular groove 5. When the plug terminal 3 is connected to the related equipment, the housing 1 and the related equipment are sealed, thereby improving the protection performance.

[0058] This utility model embodiment also provides a connector, including:

[0059] Connector housing as described in the above embodiment

[0060] The plug terminal 3 and the socket terminal 4 are adapted to be inserted into the plug channel 201 and the socket terminal 4 is adapted to be inserted into the socket channel 202. One end of the plug terminal 3 and one end of the socket terminal 4 are connected at the connection position 203.

[0061] The other end of plug terminal 3 can be used as a connection terminal to connect to external devices, and the other end of socket terminal 4 can be used as a connection terminal to connect to cable 801.

[0062] In some embodiments, there are two plug channels 201 and two socket channels 202. The two plug channels 201 are spaced apart in a first direction, and the two socket channels 202 are spaced apart in a second direction. The first direction is perpendicular to the axial direction of the plug channels 201, and the second direction is perpendicular to the axial direction of the socket channels 202.

[0063] Furthermore, the first direction and the second direction are perpendicular to each other, that is, the socket channel 202 and the plug channel 201 are perpendicular to each other.

[0064] This embodiment of the utility model provides two plug channels 201 and two socket channels 202, which are connected to form channels for the positive cable 801 and the negative cable 801 to pass through. Specifically, one set of plug channels 201 and socket channels 202 is connected to form a positive channel for accommodating the positive cable 801, and the other set of plug channels 201 and socket channels 202 is connected to form a negative channel for accommodating the negative cable 801.

[0065] In some embodiments, the connector of this utility model further includes a fixing member 7 sleeved on the plug terminal 3. At least part of the fixing member 7 is disposed in the plug channel 201. In other words, the fixing member 7 can be disposed entirely in the plug channel 201, or a portion of the fixing member 7 can be disposed in the plug channel 201 and a portion can be disposed outside the plug channel 201.

[0066] As shown in the figure, a part of the fixing member 7 sleeved on the plug terminal 3 is located inside the plug channel 201 to fix the plug terminal 3, and the other part is located outside the plug channel 201 and has an insertion groove corresponding to the plug terminal 3. The other end of the plug terminal 3 is located in the second insertion groove so that the wiring terminal of the external device can be connected to the other end of the plug terminal 3.

[0067] This utility model also provides a connection structure for a connector.

[0068] The following is in conjunction with the appendix Figure 4The connection structure of the connector according to an embodiment of the present invention is described.

[0069] The connector connection structure of this utility model embodiment includes the connector, socket connection assembly 8, and plug connection assembly 9 described in the above embodiments.

[0070] like Figure 4 As shown, the socket connection assembly 8 includes a cable 801, one end of which is provided with a first terminal 802. The terminal is inserted into the first insertion slot through the first port 102 and the socket channel 202 and connected to the socket terminal 4.

[0071] Preferably, in order to make the connection between the first terminal 802 and the socket terminal 4 more stable and tighter, the socket channel 202 is provided with a clamping member at the connection between the first terminal 802 and the socket terminal 4. The clamping member can be extended from the inner wall of the socket channel 202 toward the connection between the first terminal 802 and the socket terminal 4.

[0072] like Figure 4 As shown, the plug connection assembly 9 includes a second connection terminal 901, which is connected to the plug terminal 3.

[0073] In some embodiments, the socket connection assembly 8 further includes a tail cover 803, which is sleeved on the cable 801 and connected to the housing 1 by a snap-fit ​​to close the first opening 102.

[0074] It is understandable that by enabling the tail cap 803, which is sleeved on the cable 801, to be fixedly connected to the cable 801, and then when the tail cap 803 is connected to the housing 1 by the buckle, the cable 801 can be connected to the housing 1, that is, the cable 801 and the housing 1 can be fixed.

[0075] Therefore, simply place the tail cap 803 onto the cable 801 at a preset position, and then extend one end of the cable 801 into the socket channel 202 through the first opening 102 and the first channel 101 to connect it to the socket terminal 4. At the same time, use the snap-fit ​​structure to fix the tail cap 803 to the housing 1. It is understood that the snap-fit ​​structure is existing technology, and those skilled in the art can set different types of snap-fit ​​structures according to actual needs, which will not be elaborated here.

[0076] In some embodiments, such as Figure 4 As shown, the socket connection assembly 8 also includes a shielding assembly 804 disposed in the first channel 101. The shielding assembly 804 includes an inner shielding ring 8041 and an outer shielding ring 8042. Both the inner shielding ring 8041 and the outer shielding ring 8042 are sleeved on the cable 801, and the outer shielding ring 8042 is disposed outside the inner shielding ring 8041.

[0077] Furthermore, the socket connection assembly 8 also includes a waterproof ring 805 disposed between the housing 1 and the cable 801 and located within the first channel 101, the waterproof ring 805 being fitted onto the cable 801.

[0078] The connector structure of this utility model embodiment can prevent water from entering the connector by providing a waterproof ring 805 between the cable 801 and the housing 1, which can greatly improve the waterproof performance of the connector structure of this utility model embodiment.

[0079] The above-described embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention, and should all be included within the protection scope of the present invention.
