Description

Technical Field

[0001] This utility model relates to the field of electrical connector technology, and specifically to an electrical connector. Background Technology

[0002] A connector, also known as a plug or electrical connector, is an electronic component primarily used to connect or disconnect electrical signals in circuits or electronic devices, providing various forms of connection and signal transmission capabilities. When connecting connectors to wire harness conductors, the conductive elements within the connector are typically welded to the wire harness conductors using a hydraulic chuck to form an electrical connection. However, because the temperature during welding can easily damage the wire harness conductors and conductive elements, crimping is the most common method used.

[0003] Existing electrical connectors typically have a latching part that engages with a hydraulic chuck to press the conductive part. However, the existing latching part for pressing lacks a limit on the conductive part. When the hydraulic chuck drives the latching part to push the conductive part, the conductive part is prone to move relative to the latching part, affecting the pressing efficiency. Utility Model Content

[0004] The technical solution adopted by this utility model to solve its technical problem is: to provide an electrical connector, including a connector body and a first connector and a second connector disposed on the connector body, wherein the second connector is sleeved on the first connector;

[0005] The first connector has several insertion slots communicating with the connector body. A conductive element is provided in each insertion slot and passes through the insertion slot into the connector body. The second connector has a latching part corresponding to the insertion slot. The latching part has a slot corresponding to the conductive element. The conductive element is pressed into the slot. The conductive element includes an insertion part and a crimping part. The insertion part is inserted into the connector body along the insertion slot. The latching part and the crimping part correspond to each other. When connecting the wire of the wire harness to the conductive element, the wire of the wire harness passes through the first connector and the latching part is pushed by a hydraulic chuck to press the crimping part onto the wire of the wire harness to form an electrical connection.

[0006] Furthermore, the crimping portion is inclined away from the central axis of the first connector.

[0007] Furthermore, the end of the crimping portion near the central axis of the first connector is provided with a toothed protrusion.

[0008] Furthermore, the conductive element also includes a spiral portion disposed between the crimping portion and the plug-in portion, the spiral portion having a spiral structure.

[0009] Furthermore, the first connector includes a circular main body, and a plurality of crimping portions are disposed on the main body and distributed in a ring. A hydraulic chuck pushes the latching portion to clamp the wires of the wire harness along the radial direction of the main body.

[0010] Furthermore, the main body is provided with a plurality of positioning protrusions, the positioning protrusions and the buckling part are spaced apart, and the buckling part is inclined away from the central axis of the first connector relative to the positioning protrusions.

[0011] Furthermore, the first connector also includes a mounting portion connected to the main body. The mounting portion is cylindrical and its diameter is smaller than that of the main body. The mounting portion has a mounting protrusion, and the first connector has a mounting groove that matches the mounting protrusion.

[0012] Furthermore, the slot is provided with a stop surface that matches the pressing part, and the pressing part presses against the stop surface.

[0013] Furthermore, a guide surface is provided on the inner wall of the slot, and the conductive element is inserted into the insertion slot along the guide surface.

[0014] The beneficial effects of this utility model are: by setting the slot to limit the position of the guide, it is easy to position the guide relative to the corresponding buckle part, so that when the hydraulic chuck drives the buckle part to push the guide, the guide is not easy to move relative to the buckle part, thereby improving the crimping efficiency.

Detailed Implementation

[0026] To make the technical problem to be solved, the technical solution, and the beneficial effects of this utility model clearer, the present utility model will now be described in detail with reference to the accompanying drawings. This drawing is a simplified schematic diagram, illustrating only the basic aspects of the present utility model, and therefore only shows the components relevant to the present utility model. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0027] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 This utility model provides an electrical connector 100, including a connector body 10 and a first connector 20 and a second connector 30 disposed on the connector body 10, wherein the second connector 30 is sleeved on the first connector 20.

[0028] Please refer to Figure 6 , Figure 7 and Figure 9The first connector 20 has several insertion slots 21 communicating with the connector body 10. A conductive element 40 is provided within each insertion slot 21, and the conductive element 40 passes through the insertion slot 21 and onto the connector body 10. The second connector 30 has a latching portion 31 corresponding to the insertion slot 21. The latching portion 31 is farther from the central axis of the connector body 10 than the conductive element 40. The latching portion 31 has a corresponding slot 311, where the conductive element 40 is pressed into the slot 311. When connecting the wires of the wiring harness to the conductive element 40, the wires of the wiring harness pass through the first connector 20, and the hydraulic chuck pushes the latching portion 31 to press the conductive element 40 onto the wires of the wiring harness, forming an electrical connection.

[0029] The slot 311 provides circumferential limiting for the guide member 40, facilitating the positioning of the guide member 40 relative to the corresponding latching part 31. This ensures that when the hydraulic chuck drives the latching part 31 to push the guide member 40, the guide member 40 is less likely to move relative to the latching part 31, thereby improving crimping efficiency.

[0030] Please refer to Figure 4 , Figure 5 and Figure 6 The conductive member 40 includes a plug-in portion 41 and a crimping portion 42. The plug-in portion 41 is inserted into the connector body 10 along the plug-in groove 21. The latching portion 31 and the crimping portion 42 correspond to each other, and the crimping portion 42 is crimped onto the wires of the wire harness to form an electrical connection. The first connector 20 includes a circular body 24. A plurality of crimping portions 42 are disposed on the body 24 and distributed in a ring. When connecting the wires of the wire harness and the conductive member 40, the hydraulic chuck pushes the latching portion 31 to clamp the plurality of crimping portions 42 tightly onto the wires of the wire harness in the radial direction of the body 24.

[0031] Please refer to Figure 6 The crimping portion 42 has a toothed protrusion 421 at one end near the central axis of the first connector 20. The toothed protrusion 421 increases the contact between the conductor 40 and the wires of the wire harness, facilitating the electrical connection between the conductor 40 and the wires of the wire harness.

[0032] Please refer to Figure 3 , Figure 4 and Figure 5The first connector 20 also includes a mounting portion 25 connected to the main body 24. The mounting portion 25 is cylindrical, and its diameter is smaller than that of the main body 24. Specifically, the main body 24 has an embedded hole 241 that matches the mounting portion 25, and the mounting portion 25 is integrally formed within the embedded hole 241. The mounting portion 25 has a mounting protrusion 11, and the first connector 20 has a mounting slot 23 that matches the mounting protrusion 11. Specifically, in this embodiment, the connector body 10 has an inner hole, and the mounting protrusion 11 divides the inner hole of the connector body 10 into multiple cavities 12. The cavities 12 communicate with the insertion slot 21, and the bottom end of the conductor 40 passes through the cavity 12 along the insertion slot 21. The mounting protrusion 11 and the mounting slot 23 cooperate to facilitate the assembly and positioning of the connector body 10 and the first connector 20. At the same time, the mounting protrusion 11 and the mounting slot 23 cooperate to circumferentially limit the first connector 20, making it difficult for the first connector 20 to rotate relative to the connector body 10.

[0033] Please refer to Figure 6 The crimping portion 42 is inclined away from the central axis of the first connector 20. The inclined arrangement of the crimping portion 42 increases the space for wires of the wire harness to be inserted between the multiple conductors 40, thereby accommodating the insertion of wires of larger diameter wire harnesses.

[0034] Please refer to Figure 6 The conductive member 40 also includes a spiral portion 43 disposed between the crimping portion 42 and the insertion portion 41. The spiral portion 43 has a spiral structure, and the provision of the spiral portion 43 increases the strength of the conductive member 40.

[0035] Please refer to Figure 6 The inner wall of the slot 311 is provided with a guide surface 312, and the conductive member 40 is inserted into the insertion slot 21 along the guide surface 312. Specifically, the guide surface 312 is inclined, and the end of the guide surface 312 closer to the connector body 10 is closer to the central axis of the connector body 10 than the end of the guide surface 312 farther away from the connector body 10. The guide surface 312 guides the conductive member 40, facilitating the assembly of the conductive member 40 and the first connector 20.

[0036] Please refer to Figure 6 The slot 311 is provided with a stop surface 313 that is adapted to the crimping part 42, and the crimping part 42 presses against the stop surface 313. By setting the stop surface 313, the conductive part 40 is axially limited when it is inserted into the cavity 12 on the connector body 10 along the insertion slot 21, which facilitates positioning of the conductive part 40 relative to the first connector 20.

[0037] Please refer to Figure 5 , Figure 7 and Figure 8The main body 24 is provided with a plurality of positioning protrusions 22, which are spaced apart from the latching parts 31, and the latching parts 31 are inclined away from the central axis of the first connector 20 relative to the positioning protrusions 22. The second connector 30 is a ring structure. When the second connector 30 is sleeved on the first connector 20, the end face of the second connector 30 presses against the end face of the main body 24.

[0038] The positioning protrusion 22 provides circumferential restriction for the buckle 31, while the main body 24 provides axial restriction for the second connector 30, thereby making it less likely for the second connector 30 to rotate relative to the first connector 20, thus improving the stability of the assembly of the second connector 30 and the first connector 20.
