Description

Technical Field

[0001] The utility model relates to the technical field of connectors, in particular to a connector capable of quickly disassembling and assembling wires. Background Technique

[0002] A current connector is an electrical connector used for transmitting large currents and is widely used in multiple fields and industries.

[0003] In the interconnection of electronic circuits, a power connector is an essential component in the power circuit interconnection system. Compared with the contact terminals for transmitting signals, the design of the large-current contact terminals applied in power connectors is very crucial. Because when the contact terminals transmit large currents, if the contact resistance is large, more heat will be generated. When this heat cannot be dissipated in a timely and effective manner, a very high temperature will be generated in a local area, causing changes in the electrical performance of the power circuit. Therefore, how to reduce the conductor resistance and increase heat dissipation is the key to the design of the large-current connection system, which will directly affect the final performance of the entire transmission circuit.

[0004] In traditional connectors, the wire and the terminal connection end are fixed by welding or riveting. When using these two methods, when the wire needs to be replaced, the user needs to first disassemble the connector to expose the connection between the wire and the terminal connection end, which makes the connector inconvenient to disassemble, time-consuming, and prone to terminal damage. Content of the Utility Model

[0005] In view of this, in view of the deficiencies of the existing technology, the main purpose of the present utility model is to provide a connector capable of quickly disassembling and assembling wires, which solves the problems that the wire and the terminal connection end in the traditional connector are fixed by welding or riveting, and when replacing the wire, the connector using these two methods is inconvenient to disassemble, time-consuming, and prone to terminal damage.

[0006] To achieve the above purpose, the present utility model adopts the following technical solution: A connector capable of quickly disassembling and assembling wires, including an insulating seat and a plurality of terminals arranged on the insulating seat. Each terminal has a connection end. At least one elastic member is arranged on the insulating seat beside the corresponding connection end. The elastic member has an elastic clamping portion, and a wire clamping space is formed between the connection end and the elastic clamping portion; one end of the wire is inserted into the wire clamping space, causing the elastic clamping portion to generate elastic deformation and elastically clamp the wire with the connection end.

[0007] Furthermore, an elastic clamping hole is formed on the elastic clamping portion, and the connection end extends into the elastic clamping hole and forms a wire clamping space with the clamping surface of the elastic clamping hole.

[0008] Furthermore, the connection terminal is an elastic abutment portion 211 , and when the wires are plugged in, the elastic abutment portion 211 and the elastic clamping portion can generate elastic deformation at the same time.

[0009] Furthermore, the elastic member includes a mounting portion, a bending deformation portion and an elastic clamping portion which are integrally formed and connected, and the bending deformation portion is located between the mounting portion and the elastic clamping portion.

[0010] Furthermore, the bending deformation portion includes a first bending portion and a second bending portion, and the bending direction of the second bending portion is consistent with the direction in which the elastic clamping portion generates elastic deformation.

[0011] Furthermore, the elastic contact portion 211 is bent and has a guide slope, and the guide slope is inclined toward the elastic member.

[0012] Furthermore, a protrusion 2112 for clamping the wire is provided on the elastic abutting portion 211 .

[0013] Furthermore, one side of the mounting portion 32 is fitted to the terminal 20 for positioning and mounting, and a positioning portion 34 is extended from one end away from the bending deformation portion 33 , and the positioning portion 34 is matched with the corresponding surface of the protrusion 2112 .

[0014] Furthermore, a wiring board is provided on the rear end surface of the insulating seat, and wiring holes are opened on the wiring board corresponding to each wiring terminal, and the outlet end of the wiring hole corresponds to the wire clamping space.

[0015] Furthermore, an elastic member is provided on each corresponding connection terminal.

[0016] Compared with the prior art, the utility model has obvious advantages and beneficial effects. Specifically, it can be seen from the above technical scheme that by adding an elastic part that matches the terminal in the insulating seat, when the wire is inserted into the wire clamping space composed of the terminal and the elastic clamping part, the elastic clamping part can produce elastic deformation under the resistance of the wire, allowing the wire to pass through the wire clamping space. After the wire passes through the wire clamping space, the elastic clamping part clamps the wire by elastic reset. Compared with the traditional connection method, this connection method is more convenient to remove the wire, has a higher disassembly and assembly effect, and is not easy to damage the terminal.

[0028] Please refer to Figures 1-6 as shown, which shows the specific structure of the first preferred embodiment of the present utility model, and is a connector for quickly disassembling and assembling wires, including an insulating base 10 and a plurality of terminals 20 arranged on the insulating base. Each terminal 20 has a wiring end 21. At least one elastic member 30 is arranged on the insulating base 10 and beside the corresponding wiring end 21. The elastic member 30 has an elastic clamping portion 31. A wire clamping space 40 is formed between the wiring end 21 and the elastic clamping portion 31. One end of the wire is inserted into the wire clamping space 40, causing the elastic clamping portion 31 to generate elastic deformation and elastically clamp the wire with the wiring end 21. Compared with the traditional connector, where the connection between the wire and the terminal is fixed by welding and riveting, resulting in the need to disassemble the connector for wire replacement, the present connector for quickly disassembling and assembling wires is provided with an elastic member 30 beside the terminal 20 inserted into the insulating base 10. After the wire is inserted into the terminal 20, it can pass through the wire clamping space 40 between the terminal 20 and the elastic clamping portion 31, and the wire harness is adaptively clamped under the elastic reset of the elastic member 30.

[0029] Specifically, the wire clamping space 40 corresponds to the wiring terminal 21 of the wire inserting terminal 20, so as to facilitate the wire harness inserted into the terminal 20 to smoothly pass through the wire clamping space 40. In addition, both the wiring terminal 21 and the wire clamping space 40 have a margin space, so that wires with different cross-sectional areas can be inserted into the wire clamping space 40 and be clamped under the extrusion of the elastic clamping part 31. To ensure the strength after clamping the wire, three sides around the wire clamping space 40 are composed of the elastic clamping part 31, and the last side is composed of the wiring terminal 21, so that the wire harness passing through the wire clamping space 40 can be effectively clamped, and at the same time, the situation that the wire harness breaks away from the wire clamping space 40 due to the extrusion of the elastic clamping part 31 is avoided.

[0030] As Figure 4 shown, exemplarily, an elastic clamping hole 311 is formed on the elastic clamping part 31, and the wiring terminal 21 extends into the elastic clamping hole 311 and forms the wire clamping space 40 with the clamping surface 312 of the elastic clamping hole. By forming the elastic clamping hole 311, when the wire enters the wire clamping space 40, the elastic clamping part 31 displaces along the wiring terminal 21 through the elastic clamping hole 311, so that the wire clamping space 40 expands. Until the wire passes through the wire clamping space 40 and no driving force is applied anymore, the elastic clamping part 31 effectively clamps the wire passing through the wire clamping space 40 under its own elastic reset.

[0031] Specifically, the wiring terminal 21 passes through the elastic clamping hole 311. At this time, the elastic clamping hole 311 corresponding to the inner cavity part of the wiring terminal 21 is called the wire clamping space 40, and vice versa, the space that does not correspond to the inner cavity part of the wiring terminal 21 is still called the elastic clamping hole 311. The elastic clamping hole 311 is rectangular and has a cross-sectional area larger than that of the wire. When the elastic clamping part 31 is extruded by the wire, the elastic clamping hole 311 moves towards the wiring terminal 21, and the diameter of the wire clamping space 40 expands to facilitate the wire to pass through the wire clamping space 40.

[0032] As Figure 4 shown, exemplarily, the wiring terminal 21 is an elastic abutting part 211. When the wire is inserted, the elastic abutting part 211 and the elastic clamping part 31 can simultaneously generate elastic deformation. The wiring terminal 21 is an extension part of the terminal 20 and is strip-shaped. When the wire enters the wire clamping space 40, the elastic wiring terminal 21 will deform and displace together with the elastic clamping part 31. When the wire stops moving, under the elastic reset of the wiring terminal 21 and the elastic clamping part 31, the wire located between the wiring terminal 21 and the elastic clamping part 31 can be clamped more tightly to avoid unnecessary separation of the wire and the terminal 20.

[0033] In another embodiment, the wiring terminal 21 does not have elasticity, and the elastic displacement of the elastic clamping part 31 itself can still effectively clamp the wire passing through the wire clamping space 40.

[0034] As Figure 4As shown, exemplarily, the elastic member 30 includes an integrally formed mounting portion 32, a bending and deforming portion 33, and an elastic clamping portion 31. The bending and deforming portion 33 is located between the mounting portion 32 and the elastic clamping portion 31. The bending and deforming portion 33 is located between the mounting portion 32 and the elastic clamping portion 31. The mounting portion 33 abuts against one surface of the terminal 20 to limit the elastic member 30. Through the arrangement of the bending and deforming portion 33, the elastic clamping portion 31 has the function of elastic displacement.

[0035] Specifically, among the mounting portion 32, the bending and deforming portion 33, and the elastic clamping portion 31 that make up the elastic member 30, the bending and deforming portion 33 abuts against the inner wall of the insulating base 10, and the mounting portion 32 abuts against one plane of the terminal 20 to limit the elastic movement direction of the elastic member 20, so that the movement direction of the elastic clamping portion 31 is to cooperate with the wiring terminal 21 to clamp the wire.

[0036] As Figure 4 shown, exemplarily, the bending and deforming portion 33 includes a first bending portion 331 and a second bending portion 332. The bending direction of the second bending portion 332 is the same as the direction of elastic deformation of the elastic clamping portion 33. The first bending portion 311 is located between the mounting portion 32 and the second bending portion 332, and the second bending portion 332 is located between the first bending portion 311 and the elastic clamping portion 31. Through the opening of the first bending portion 331, the elastic clamping portion 31 can perform elastic displacement, and the opening of the second bending portion 332 can limit the displacement direction of the elastic clamping portion 31 to ensure that the elastic clamping portion 31 can effectively clamp the wire through elastic displacement.

[0037] Specifically, the elastic member 30 is in the shape of a plate and is made of metal or plastic, so that the elastic member 30 has a better elastic displacement effect.

[0038] As Figure 4 shown, exemplarily, the elastic abutting portion 211 is bent and has a guiding inclined surface 2111. The inclined direction of the guiding inclined surface 2111 approaches the elastic member 30. The elastic abutting portion 211 is the part of the terminal 20 passing through the elastic clamping hole 311. Through the opening of the guiding inclined surface 2111 on the elastic abutting portion 211, the wire inserted into the insulating base 10 can be guided by the guiding inclined surface 2111 and inserted into the wire clamping space 40.

[0039] As Figure 4 shown, exemplarily, the elastic abutting portion 211 is provided with a protrusion 2112 for clamping the wire. The part of the elastic abutting portion 211 corresponding to the inner cavity of the wire clamping space 40 contains a protrusion 2112 extending towards the inner cavity of the wire clamping space 40. Through the protrusion 2112, the wire inserted into the wire clamping space 40 can be better clamped.

[0040] As Figure 4As shown, exemplarily, one side of the mounting portion 32 is attached to the terminal 20 for positioning and installation, and a positioning portion 34 extends from one end away from the bending and deforming portion 33. The positioning portion 34 is adapted to the corresponding surface of the protrusion 2112. By partially extending the mounting portion 32 to the opposite side of the protruding end of the elastic abutting portion 211, that is, after entering the inner groove, the position of the mounting portion 32 is restricted, thereby avoiding the offset of the elastic member 30 under the extrusion during wire insertion.

[0041] As Figure 4 shown, exemplarily, a wiring board 50 is provided on the rear end surface of the insulating base 10. Wiring holes 51 are provided on the wiring board 50 corresponding to the respective wiring terminals 21, and the outlet ends of the wiring holes 51 correspond to the wire clamping space 40. The wiring board 50 can guide the wire inserted into the wiring hole 51 to be inserted into the wire clamping space 40 as it moves through the wiring hole 51 thereon, and clamp the wire through the elastic displacement of the elastic member 30.

[0042] An elastic member 30 is provided corresponding to each wiring terminal 21.

[0043] In summary, the design focus of the present invention lies in that through the arrangement of the elastic member 30 in the insulating base 10 and the cooperation between the elastic member 30 and the terminal 20 originally inserted in the insulating base 10, when the wire is inserted into the wiring terminal 21 of the terminal 20, the elastic member 30 can generate elastic displacement under the extrusion of the wire. By expanding the elastic displacement of the elastic member 30, the diameter of the wire clamping space 40 between the wiring terminal 21 and the elastic clamping portion 31 is increased, so that wires with different cross-sectional areas can smoothly pass through the wire clamping space 40. After the wire passes through the wire clamping space 40, the elastic clamping portion 31 is reset to cooperate with the wiring terminal 21 to clamp the wire.

[0044] The above are only preferred embodiments of the present invention, and do not impose any limitation on the technical scope of the present invention. Therefore, any minor modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention still fall within the scope of the technical solution of the present invention.
