Description

Technical Field

[0001] This utility model relates to the field of connector technology, and in particular to an electrical connector that is easy to wire. Background Technology

[0002] Electrical connectors, also known as circuit connectors, are electronic components used to connect or disconnect circuits. They transmit current and signals between different circuits, devices, or systems through the mating of plug contacts and socket contacts. Traditional electrical connectors mostly use screws or screwdrivers to open a cage spring structure to connect wires, requiring additional tools such as screwdrivers for operation, which is relatively cumbersome.

[0003] Currently, some electrical connectors capable of quick wire locking have appeared on the market. For example, Chinese patent document CN212462134U discloses an electrical connector with a quick wire locking assembly. The wire locking assembly of this electrical connector includes at least one insulating base, and at least one wire locking cavity is provided in the insulating base. A shaft is provided in the wire locking cavity. A reset member is provided on the shaft and a pressing spring is provided on the outside of the reset member. By pressing the limiting end of the wire locking wrench downward until the wire locking state a, the locking end of the wire locking wrench presses against the driving end of the pressing spring. The driving end drives the pressing spring to deflect around the pivot point. At the same time, the driving end squeezes the reset end to deform until the wire locking end presses and locks the cable. The shaft of this type of electrical connector is integrally molded within the locking cavity of the insulating base, and uses the same insulating plastic material as the insulating base. 1. When assembling the reset piece and the clamping spring, the pivot part of the reset piece must be precisely aligned with the shaft to be inserted. However, due to the possibility of slight demolding deformation or burrs on the plastic shaft after molding, and the possibility of slight tolerances in the reset piece, misalignment may lead to assembly difficulties, requiring repeated adjustments by the operator, or even forceful pressing, reducing assembly efficiency. 2. The reset piece and clamping spring require frequent rotation for operation. The friction between the reset piece and the plastic shaft will gradually wear down the plastic shaft, generating debris, changing the mating dimensions, increasing the clearance, causing radial wobble of the reset piece, inaccurate positioning, and potential skewing during wire clamping. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide an electrical connector that is easy to wire, so that wiring and wire removal can be achieved without the need for additional tools, and the assembly process of the wire clamping spring is smooth, ensuring the reliable positioning and movement of the wire clamping spring.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: An easy-to-wire electrical connector includes an insulating shell, a metal contact assembly, and a handle. One end of the insulating shell has a pin socket communicating with an internal cavity, and the other end has a wire socket communicating with the internal cavity. The metal contact assembly is installed within the cavity of the insulating shell and includes a contact clip and a wire clamping spring. One end of the contact clip has a forked clamping portion near the pin socket, and the other end has a positioning portion near the wire socket. A vertically mounted mounting plate is integrally connected to the rear side of the positioning portion, and a vertically mounted pivot is integrally connected to the front side of the mounting plate. The wire clamping spring is a U-shaped spring with a pivot portion in the middle, an abutment portion at the upper end, and a wire clamping portion at the lower end. The pivot portion is rotatably connected to the pivot, and the wire clamping portion is used to press the wire firmly against the positioning portion. The handle is rotatably connected to the insulating shell and located above the wire clamping spring. The handle has a limiting portion for limiting the abutment portion.

[0006] In some embodiments, the pivot is a hollow shaft, which is composed of two circular arc plates.

[0007] Compared with the prior art, this utility model achieves at least the following beneficial effects: 1. Insert the wire into the wire socket, allowing it to enter the gap between the clamping part and the positioning part. Then, turn the handle downwards to rotate it clockwise back to its original position. The limiting part of the handle can press against the abutting part of the clamping spring, limiting the rotation angle of the clamping spring. This allows the clamping part to press the wire against the positioning part of the contact clip, achieving wire locking and electrical connection between the wire and the contact clip. To remove the wire, simply turn the handle upwards to rotate it counterclockwise to open it. The limiting part of the handle rotates to a higher position, releasing the pressing state of the limiting part against the abutting part. This allows the clamping spring to rotate upwards at a certain angle, facilitating wire removal. No additional tools are needed for wiring and wire removal, making it simple, convenient, fast, and efficient. 2. By setting an integrally connected metal pivot on the mounting plate, during assembly, the pivot part of the clamping spring can be first fitted onto the metal pivot, and then this sub-assembly can be installed as a whole into the cavity of the insulating shell. The metal pivot is manufactured by precision stamping, and its dimensional tolerance can be controlled very well. Moreover, the pivot part of the metal pivot and the clamping spring adopts a small clearance fit, which facilitates the alignment and makes the assembly process smoother. In addition, the wear resistance of the metal pivot is far superior to that of plastic materials, reducing wear and ensuring the reliable positioning and movement of the clamping spring.

[0012] like Figures 1-6As shown in the embodiment of this application, a convenient electrical connector includes an insulating shell 1, a metal contact assembly 2, and a handle 3. The insulating shell 1 has a pin socket 121 communicating with an internal cavity at one end and a wire socket 111 communicating with the internal cavity at the other end. The metal contact assembly 2 is installed within the cavity of the insulating shell 1 and includes a contact clip 21 and a wire clamping spring 22. One end of the contact clip has a forked clamping portion 211 near the pin socket 121, and the other end has a positioning portion 212 near the wire socket 111. A vertically arranged mounting plate 213 is integrally connected to the rear side of the positioning portion 212, and a vertically arranged pivot 214 is integrally connected to the front side of the mounting plate 213. The wire clamping spring 22 has a pivot portion 221 in the middle and an abutment portion 22 at the upper end. 2. A U-shaped spring piece with a wire clamping part 223 is provided at the lower end. The pivot part 221 is rotatably connected to the pivot 214, so that the wire clamping spring piece 22 can rotate around the axis of the pivot 214. The metal pivot 214 integrally connected to the mounting plate 213 replaces the commonly used plastic shaft structure, which can ensure the reliable positioning and movement of the wire clamping spring piece 22 and solve the problem of assembly inconvenience caused by the plastic shaft structure. The wire clamping part 223 is used to press the wire onto the positioning part 212, thereby realizing the electrical connection between the wire and the metal contact component 2. The handle 3 is rotatably connected to the insulating shell 1 and located above the wire clamping spring piece 22. The handle 3 is provided with a limiting part 34 for limiting the abutment part 222.

[0013] The working principle of this utility model is as follows: Insert the wire into the wire socket 111. The wire enters the gap between the clamping part 223 and the positioning part 212. Then, turn the handle 3 downwards to rotate it clockwise back to its original position. The limiting part 34 of the handle 3 can press against the abutment part 222 of the clamping spring 22, limiting the rotation angle of the clamping spring 22. This allows the clamping part 223 to press the wire against the positioning part 212 of the contact clip, thus locking the wire and electrically connecting the wire to the contact clip. Then, connect the PCB socket 6 to the insulating shell 1. The pins of the PCB socket 6 are inserted into the pin socket 121 and contact the forked clamping part 211 of the contact clip, thus achieving an electrical connection between the PCB socket 6 and the wire. When removing the wire, simply turn the handle 3 upwards to rotate it counterclockwise to open it. The limiting part 34 of the handle 3 rotates to a higher position, releasing the pressing state of the limiting part 34 against the abutment part 222, allowing the clamping spring 22 to rotate upwards at a certain angle, facilitating the removal of the wire. This invention enables wiring and wire removal operations without the need for additional tools, making it simple, convenient, fast, and efficient. A metal pivot 214 is integrally connected to the mounting plate 213. During assembly, the pivot part 221 of the clamping spring 22 can be first fitted onto the metal pivot 214. After assembly, this sub-component can be installed as a whole into the cavity of the insulating shell 1. The metal pivot 214 is manufactured by precision stamping, and its dimensional tolerance can be controlled very well. The metal pivot 214 and the pivot part 221 of the clamping spring 22 have a small clearance fit, which facilitates positioning. Alternatively, it can be pressed in at once using automated equipment, making the assembly process smoother. Moreover, the wear resistance of the metal pivot 214 is far superior to that of plastic materials, reducing wear and ensuring the reliable positioning and movement of the clamping spring 22.

[0014] Optionally, the pivot 214 is a hollow shaft, which is composed of two arc-shaped plates. The pivot 214 is integrally stamped by the mounting plate 213, reducing the processing difficulty.

[0015] Specifically, the insulating shell 1 includes multiple integrally connected shell bodies 11 and multiple integrally connected covers 12; wire sockets 111 are provided at one end of each shell body 11, and each shell body 11 has a connection port 112 at the end away from the wire sockets 111; pin sockets 121 are provided at the end of each cover 12 away from the shell body 11, and the cover 12 is detachably connected to the connection port 112 end of the shell body 11. In this embodiment, the number of shell bodies 11 and covers 12 can be designed according to requirements, and a corresponding number of metal contact components 2 and handles 3 can be assembled. Each cover 12 has a slot vertically arranged at one end near the shell body 11, and a rectangular snap-fit ​​122 extending through the top of the cover 12 is provided above the slot; each shell body 11 has a vertically arranged insert 113 integrally connected to the connection port 112 end, and a snap fastener 114 with a right-angled trapezoidal longitudinal section integrally connected to the top of the insert 113. When assembling the shell body 11 and the cover 12, the insert 113 is inserted into the slot, and the snap fastener 114 is engaged with the snap-fit ​​122.

[0016] Each cover 12 has a plug-in portion 123 at one end away from the main body 11. The plug-in portion 123 matches the slot designed on the PCB socket 6. The plug-in portion 123 is used to plug into the PCB socket 6. An elastic retaining strip 124 is also integrally connected to the cover 12 above the plug-in portion 123. The front end of the elastic retaining strip 124 extends downward to form a retaining portion 1241. The retaining portion 1241 matches the step designed on the PCB socket 6. It is used to connect with the step of the PCB socket 6 to achieve a reliable connection.

[0017] Each housing body 11 has an opening at the top; the handle 3 is an L-shaped block with a connecting shaft 31 on the front and back, a handhold 32 at one end, and a pushing part 33 at the other end. The connecting shaft 31 is rotatably connected to the housing body 11, and the handhold 32 extends through the opening. The handhold 32 has anti-slip texture 321. When the handle 3 is rotated counterclockwise, the pushing part 33 pushes the abutment part 222, thereby driving the wire clamping part 223 to rotate clockwise, which widens the gap between the wire clamping part 223 and the positioning part 212, making it easier to insert the wire. Furthermore, the limiting part 34 extends downward in the middle of the handle 3 and is spaced apart from the pushing part 33; the end of the abutment part 222 is curved to form a limiting groove 2221. The limiting groove 2221 matches the limiting part 34. The cooperation between the limiting part 34 and the limiting groove 2221 of the abutment part 222 can limit the maximum angle of clockwise rotation of the wire clamping spring 22.

[0018] Optionally, a power-on test hole 4 is provided on the handle 3 above the pivot part 221 of the clamping spring 22. The power-on test hole 4 is connected to the internal cavity of the insulating shell 1. During maintenance or debugging, there is no need to disassemble the electrical connector or disconnect the circuit. The test instrument can be directly connected through the test hole and electrically connected to the clamping spring 22 to perform relevant circuit testing operations.

[0019] Optionally, the forked clamping part 211 includes a first clamping spring 211a and a second clamping spring 211b that are integrally connected and symmetrically arranged vertically. The front section of the first clamping spring 211a approaches the front section of the second clamping spring 211b, and the front section of the first clamping spring 211a is inclined to bend upward, while the front section of the second clamping spring 211b is inclined to bend downward.

[0020] Optionally, the upper surface of the positioning part 212 is provided with several anti-slip grooves 5 to increase friction and ensure that the wire is securely locked.

[0021] 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.
