目前,传统的电连接器大多采用螺钉或螺丝刀打开笼式弹簧的结构形式实现电线的连接,接线时,首先将电线插入电连接器,然后需要使用螺钉将电线压紧在接线端子上,或者需要使用螺丝刀手动拨动开笼式弹簧以实现对电线的夹紧,接线过程中需要额外借助螺丝刀等工具进行操作,操作比较繁琐,降低了接线效率
[0010] Before inserting the wire, the angle of the toggle handle is adjusted by rotating the toggle part counterclockwise. The position of the limiting part of the toggle handle is raised relative to the initial position, allowing the wire clamping spring to rotate clockwise by a certain angle, creating a gap between the clamping part of the wire clamping spring and the contact part of the mating spring. After the wire is inserted into the wire socket, the wire passes through the wire socket and enters the gap area between the clamping part and the contact part. Finally, the toggle handle is rotated clockwise to reset, and the limiting part blocks the abutment part, thereby limiting the clamping spring. This allows the clamping part to press the wire tightly against the contact part of the mating spring, achieving quick locking of the wire without the need for additional tools, thus improving wiring efficiency. The forked clamping part at the other end of the mating spring connects to the male connector pin, thereby achieving an electrical connection between the wire and the male connector pin.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of connector technology, and in particular to an electrical connector for quick wire locking. Background Technology
[0002] An electrical connector is an electronic component used to connect or disconnect circuits. It transmits current and signals between different circuits, devices, or systems through the cooperation of plug contacts (male terminals, such as pins) and socket contacts (female terminals, such as jacks). It is an indispensable key component in electronic equipment. Currently, most traditional electrical connectors use a screw or screwdriver to open a cage spring to connect wires. During wiring, the wire is first inserted into the connector, and then a screw is used to press the wire firmly onto the terminal block, or a screwdriver is used to manually move the cage spring to clamp the wire. This wiring process requires additional tools such as screwdrivers, making it cumbersome and reducing wiring efficiency. Utility Model Content
[0003] The technical problem to be solved by this utility model is to provide an electrical connector that can quickly lock wires without the need for additional tools for wiring operations, thereby improving wiring efficiency.
[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:
[0005] A quick-locking electrical connector includes a plug-in housing and multiple insulating bases detachably connected to the plug-in housing. The insulating bases are rectangular shells with a wire insertion hole communicating with an inner cavity on one lower side. The insulating bases are provided with mating springs, wire clamping springs, and a lever. The mating springs are strip-shaped springs with a contact portion at one end and a forked clamping portion at the other end. The contact portion is installed at the inner bottom of the insulating base, and the forked clamping portion is located outside the insulating base and inserted into the plug-in housing. The wire clamping springs are located above the contact portion. A V-shaped spring piece is provided with a first pivot in the middle, a wire clamping part at one end, and an abutment part at the other end. The first pivot is rotatably connected to the inner wall of the insulating base. The wire clamping part extends downward and cooperates with the contact part to clamp the wire. The toggle handle is located above the wire clamping spring piece. It is an L-shaped block with a second pivot in the middle, a limiting part at one end, and a toggle part at the other end. The second pivot is rotatably connected to the inner wall of the insulating base. The limiting part and the abutment part cooperate to limit the rotation angle of the wire clamping spring piece. The toggle part extends out of the top of the insulating base.
[0006] In some embodiments, the inner sidewall of the insulating base is vertically fixedly connected to a first positioning shaft and a second positioning shaft; the first pivot portion of the wire clamping spring is rotatably connected to the first positioning shaft, and the second pivot portion of the toggle handle is rotatably connected to the second positioning shaft.
[0007] In some embodiments, the contact portion of the clamping spring is provided with a strip-shaped opening; the outer side of the limiting portion of the toggle handle is integrally provided with a downwardly protruding connecting plate, and a limiting step is formed between the connecting plate and the limiting portion. The connecting plate passes through the strip-shaped opening, and the limiting step is used to abut against the top of the contact portion to limit the rotation angle of the clamping spring.
[0008] In at least one embodiment, a support rod is provided at the lower end of the connecting plate. The support rod is located below the strip-shaped opening and is used to support the abutment portion to limit the downward rotation of the clamping spring.
[0009] Compared with the prior art, this utility model achieves at least the following beneficial effects:
[0010] Before inserting the wire, the angle of the toggle handle is adjusted by rotating the toggle part counterclockwise. The position of the limiting part of the toggle handle is raised relative to the initial position, allowing the wire clamping spring to rotate clockwise by a certain angle, creating a gap between the clamping part of the wire clamping spring and the contact part of the mating spring. After the wire is inserted into the wire socket, the wire passes through the wire socket and enters the gap area between the clamping part and the contact part. Finally, the toggle handle is rotated clockwise to reset, and the limiting part blocks the abutment part, thereby limiting the clamping spring. This allows the clamping part to press the wire tightly against the contact part of the mating spring, achieving quick locking of the wire without the need for additional tools, thus improving wiring efficiency. The forked clamping part at the other end of the mating spring connects to the male connector pin, thereby achieving an electrical connection between the wire and the male connector pin.

[0020] like Figures 1-6As shown in the embodiment of this application, a quick-locking electrical connector includes a plug-in housing 1 and multiple insulating bases 2 detachably connected to the plug-in housing 1. Each insulating base 2 is a rectangular shell, and a wire socket 21 communicating with the inner cavity is provided on the lower part of one side of the insulating base 2. The insulating base 2 is provided with a mating spring 3, a wire clamping spring 4, and a toggle handle 5. The mating spring 3 is a strip-shaped spring with a contact part 31 at one end and a forked clamping part 32 at the other end. The contact part 31 is installed on the inner bottom of the insulating base 2, and the forked clamping part 32 is located outside the insulating base 2 and inserted into the plug-in housing 1. The wire clamping spring 4 is located on the contact part 31. The insulating base 2 has a V-shaped spring piece with a first pivot part 41 in the middle, a wire clamping part 42 at one end, and an abutment part 43 at the other end. The first pivot part 41 is rotatably connected to the inner wall of the insulating base 2. The wire clamping part 42 extends downward and cooperates with the contact part 31 to clamp the wire 40. The lever handle 5 is located above the wire clamping spring piece 4. The lever handle 5 is an L-shaped block with a second pivot part 51 in the middle, a limiting part 52 at one end, and a lever part 53 at the other end. The second pivot part 51 is rotatably connected to the inner wall of the insulating base 2. The limiting part 52 cooperates with the abutment part 43 to limit the rotation angle of the wire clamping spring piece 4. The lever part 53 extends out of the top of the insulating base 2. Before inserting the wire 40 into the wire socket 21, the angle of the toggle handle 5 is adjusted by rotating the toggle part 53 counterclockwise. The position of the limiting part 52 of the toggle handle 5 is raised relative to the initial position, allowing the wire clamping spring 4 to rotate clockwise by a certain angle, creating a gap between the wire clamping part 42 of the wire clamping spring 4 and the contact part 31 of the mating spring 3. After inserting the wire 40 into the wire socket 21, the wire 40 enters the gap area between the wire clamping part 42 and the contact part 31. Finally, the toggle handle 5 is rotated clockwise to reset, and the limiting part 52 of the toggle handle 5 is reset. The limiting part 52 blocks the abutment part 43, thereby achieving the clamping of the wire clamping spring 4. The limiting mechanism allows the clamping part 42 to press the wire 40 tightly against the contact part 31 of the insert spring 3, while the forked clamping part 32 at the other end of the insert spring 3 connects to the male connector pin, thereby achieving an electrical connection between the wire 40 and the male connector pin. This enables quick locking of the wire without the need for additional tools for wiring and wire removal, improving wiring efficiency. Furthermore, during assembly, the insert spring 3, the clamping spring 4, and the toggle handle 5 are mounted on the insulating base 2, and then each insulating base 2 is sequentially mounted on the plug-in housing 1, thereby enabling electrical connections between multiple sets of wires 40 and multiple sets of male connector pins.
[0021] Specifically, the inner wall of the insulating base 2 is vertically fixedly connected to a first positioning shaft 6 and a second positioning shaft 7; the first pivot part 41 of the wire clamping spring 4 is rotatably connected to the first positioning shaft 6, and the second pivot part 51 of the toggle handle 5 is rotatably connected to the second positioning shaft 7.
[0022] The contact portion 43 of the wire clamping spring 4 has a strip-shaped opening 431; the outer side of the limiting portion 52 of the toggle handle 5 has an integrally formed downward protruding connecting plate 8, and a limiting step 9 is formed between the connecting plate 8 and the limiting portion 52. The connecting plate 8 passes through the strip-shaped opening 431, and the limiting step 9 is used to abut against the top of the contact portion 43, thereby limiting the rotation angle of the wire clamping spring 4. Furthermore, the lower end of the connecting plate 8 is provided with a support rod 10, which is located below the strip-shaped opening 431, and the length of the support rod 10 is greater than the width of the strip-shaped opening 431. When the wire 40 is inserted, the support rod 10 is used to support the contact portion 43 to limit the downward rotation of the wire clamping spring 4, thereby facilitating the insertion of the wire 40 into the insulating base 2 from the wire socket 21.
[0023] The inner bottom of the insulating base 2 is provided with a limiting groove 22, and the lower part of the side of the insulating base 2 away from the wire socket 21 is provided with a first clearance opening 23; the rear side of the contact part 31 of the insert spring 3 is provided with a limiting piece 311 that engages with the limiting groove 22. The limiting piece 311 and the limiting groove 22 cooperate to limit the insert spring 3 in the left and right directions. The middle part of the insert spring 3 is inserted into the first clearance opening 23, and the middle part of the insert spring 3 is provided with an elastic protrusion 33 for abutting against the upper end of the first clearance opening 23. By abutting against the first clearance opening 23 with the elastic protrusion 33, the connection between the insert spring 3 and the insulating base 2 can be strengthened.
[0024] The plug-in housing 1 is provided with a male connector pin socket 11. The upper and lower end faces of the male connector pin socket 11 are respectively provided with an upper protrusion 111 and a lower protrusion 112 along the length direction. The forked clamping part 32 includes an upper clamping spring 321 and a lower clamping spring 322 integrally connected and spaced apart vertically. The upper clamping spring 321 and the lower clamping spring 322 are inserted into the male connector pin socket 11, and the upper clamping spring 321 is inserted into the male connector pin socket 11. The front sections of the upper and lower clamping springs 321 and 322 are brought together, and the rear sections of the upper and lower clamping springs 322 abut against the upper protrusion 111 and the lower protrusion 112 respectively. The rear end of the upper clamping spring 321 is provided with an upward-curved guide plate 3211. After the upper and lower clamping springs 321 and 322 are inserted into the male connector pin socket 11, the guide plate 3211 is used to abut against the side wall of the upper protrusion 111 to achieve positional alignment. Furthermore, the front sections of the upper clamping spring 321 and the lower clamping spring 322 are provided with protruding contact points 20. When the male connector pin is inserted into the male connector pin socket 11 of the plug-in housing 1, the male connector pin opens up the front sections of the upper clamping spring 321 and the lower clamping spring 322 and inserts between the upper clamping spring 321 and the lower clamping spring 322. The male connector pin contacts the contact points 20 of the upper clamping spring 321 and the lower clamping spring 322 to achieve electrical connection.
[0025] The plug-in housing 1 is provided with multiple slots 12 that match the insulating base 2. The top and bottom of the slots 12 are provided with rectangular bayonet slots 13. The top and bottom of the insulating base 2 are provided with locking blocks 25 with a longitudinal cross section of right-angled trapezoids. Multiple insulating bases 2 are respectively inserted into multiple slots 12, and are reliably connected by locking blocks 25 and bayonet slots 13.
[0026] The top of the insulating base 2 is provided with a second clearance opening 24; the toggle part 53 of the toggle handle 5 protrudes from the second clearance opening 24.
[0027] A locking block 30 is vertically fixed to the top of the insulating base 2. The outer wall of the locking block 30 has an arc-shaped groove (not shown in the figure). The actuating part 53 of the toggle handle 5 has a locking slot 531 that matches the locking block 30. The inner wall of the locking slot 531 has an arc-shaped buckle that matches the buckle (not shown in the figure). After the wire 40 is inserted, when the reset toggle handle 5 is rotated clockwise, the locking block 30 is inserted into the locking slot 531 on the actuating part 53, and locking is achieved through the cooperation of the groove and the buckle, thereby locking the wire 40.
[0028] It should be understood that all the above embodiments are exemplary and not restrictive. Any modifications, equivalent changes and alterations made by those skilled in the art to the specific embodiments described above under the concept of this utility model shall still fall within the scope of the technical solution of this utility model.
