[0002] In the field of low-voltage electrical components manufacturing, the current domestic equipment wiring frame design mostly uses rivet-type screws and wire-pressing pads. In the traditional wiring process, operators need to use a blade or other tools to remove the insulating protective layer on the outside of the equipment connection wire, expose the internal conductive copper wire, and fix it under the screws under the wiring frame to achieve electrical connection.

[0003] However, this traditional wiring method has several obvious defects: To ensure the safety of the wiring process, the power supply must be cut off first, which not only increases the complexity of the operation process, but also prolongs the working time and reduces the overall work efficiency.

[0040] Reference Figure 1 to Figure 7 , which is the first embodiment of the present invention, and provides a connection fastener for equipment wiring, which includes a connection unit 1, including a fastening component 11, a wire frame 12 arranged outside the fastening component 11, a fastening frame 13 arranged outside the wire frame 12, a snap-fit ​​component 14 arranged inside the fastening frame 13, and a stopper 15 arranged at the top of the fastening frame 13;

[0041] It also includes a cable 2 arranged at the bottom of the fastening component 11 and a connection terminal 3 arranged at the top of the wire frame 12 .

[0045] The end contact surface 161 of the lead plate 16 is electrically connected to the connection terminal 3 .

[0046] Furthermore, the U-shaped clip 111 includes an upper end surface 1111 and a lower end surface 1112 protruding from the bottom of the upper end surface 1111;

[0047] One side of the spring 113 is fixedly connected to the top of the upper end surface 1111 , and the other side is fixedly connected to the bottom surface of the terminal 123 .

[0052] The driving plate 142 includes a connecting frame 1421 disposed at an end thereof, and two sets of extension arms 1422 disposed at the bottom of the connecting frame 1421 .

[0053] Furthermore, the stopper 15 includes two groups of support columns 151 fixedly arranged at the ends of the fastening frame 13, a pressure rod 152 hinged between the two groups of support columns 151, a connecting rod 153 hinged at the bottom of the pressing rod 152, and a clamping rod 154 arranged at the bottom of the connecting rod 153;

[0054] The clamping rod 154 passes through the fastening frame 13 and is fixedly clamped on the connecting frame 1421 .

[0055] Furthermore, the lead plate 16 also includes a wire holder 162 disposed at the bottom thereof;

[0056] The wire holder 162 includes a puncture 1621 disposed at an end thereof.

[0057] It should be noted that the connection unit 1 in this embodiment is a plurality of sub-connection terminals arrayed in the electrical box. The fastening assembly 11 is a pressure-applying end for fastening the wiring of the device, and can limit the cable 2 in the wire frame 12 by pressing. The wire frame 12 can lead the current from the terminal 3 to the cable 2, making it easier to draw the current. The buckle 14 can apply a downward pressure to the fastening assembly 11 through the pressing action of the limiter 15, thereby fixing the cable 2 at the bottom of the wire frame 12.

[0058] Preferably, the fastening assembly 11 is composed of a U-shaped clip 111, a positioning rod 112 penetrating the inner side of the U-shaped clip 111, and a spring 113 at the end of the U-shaped clip 111. The U-shaped clip 111 is U-shaped, and its upper end surface 1111 is a pressure surface that bears the force of the spring 113 installed above, and its lower end surface 1112 is an extrusion surface for extruding the cable 2. A positioning hole is provided on the bottom end surface of the upper end surface 1111, and a positioning rod 112 is installed in the positioning hole. The upper end of the positioning rod 112 is limited in the positioning hole, and the lower end of the positioning rod 112 is limited on the lower end surface 1112. The spring 113 is compressed on the upper end surface 1111 and the bottom surface of the terminal 123.

[0059] Preferably, the wire frame 12 is in the shape of a square, with the upper end being the wiring terminal 123, the bottom being the fastening end 121, and the two sides in the middle forming a whole through the connecting frame 122. A sliding groove 1221 is provided on the side wall of the connecting frame 122, and the sliding groove 1221 provides a connection space for the positioning rod 112 to connect with the fastener 14. A clamping groove is provided on one side wall of the connecting frame 122, which can be used to clamp the lead plate 16. The lead plate 16 is in the shape of a J, and the bottom thereof is a wire seat 162, such as Figure 3 As shown, the lead plate 16 is composed of a wire seat 162 at the bottom and a contact surface 161 at the end. The wire seat 162 at the bottom of the lead plate 16 is a rigid conductive metal, such as a steel alloy, which is convenient for the wire seat 162 to pierce and contact with the cable for conduction. The lead plate 16 body and the contact surface 161 are made of copper material with good ductility, which is convenient for fitting the connection frame 122 and the terminal 123. When the wire seat 162 pierces the cable cortex and contacts the inner copper wire, the wiring forms a path, and the current in the terminal 3 passes through the contact surface 161 and the lead plate 16, and is finally led to the cable 2.

[0060] Preferably, the shape of the fastening end 121 and the lower end surface 1112 after being matched together is arc-shaped, which is convenient for clamping the cable 2 therein. A stud 1231 is welded at the end of the terminal 123, and the terminal 3 can be sleeved on the stud 1231, and the terminal 3 can be fixed thereon by tightening it with an external nut. The wire seat 162 embedded in the fastening end 121 has an upwardly protruding puncture 1621, and the puncture 1621 fits the shape of the wire seat 162, both of which are arc-shaped. The puncture 1621 is in the shape of an arc-shaped knife tip, which is convenient for penetrating the outer rubber skin of the cable 2 and directly contacting the copper wire of the cable 2. The puncture 1621 is in multiple groups, which can increase the probability of contact and power supply between the puncture 1621 and the copper wire of the cable 2, and strengthen the clamping strength between the fastening end 121 and the cable 2. A group of rubber gaskets are fixedly clamped in the arc groove of the lower end surface 1112, and the gaskets can prevent the puncture 1621 at the bottom of the cable 2 from puncturing too deeply and cutting the cable 2.

[0061] Preferably, the bottom of the positioning rod 112 is clamped on the upper surface of the lower end surface 1112, and the support plate 1121 is welded to the rod body of the positioning rod 112, and the support plate 1121 is in an X shape, such as Figure 3 A space can be reserved for the lead plate 16 to be installed in the middle of the connection frame 122. In addition, two sets of symmetrical sliding grooves 1221 are provided on both side walls of the connection frame 122. A corner of the support plate 1121 is limited in each set of sliding grooves 1221 so that it can be slidably limited inside the connection frame 122.

[0062] Preferably, the buckle 14 can drive the positioning rod 112 to rise and fall, thereby achieving the fastening and piercing effect on the cable 2. The buckle 14 is composed of two sets of driving plates 142 slidably arranged inside the sliding groove 1221 of the side wall of the connecting frame 122, and a top block 141 at the bottom of the driving plate 142. Figure 3 As shown in FIG. 1 , the driving plate 142 is a U-shaped driving block. The driving plate 142 is composed of a connecting frame 1421 at the end and two groups of extension arms 1422 at the bottom of the connecting frame 1421. Figure 4 The extension arm 1422 is provided with a clamping groove 14221, in which a corner of the support plate 1121 can be clamped, so that the four corners on both sides of the support plate 1121 can be fixed in the extension arms 1422 on both sides.

[0063] Preferably, a through hole is provided on the end surface of the connecting frame 1421, which is connected to the limiting member 15. Figure 5As shown. The limiting member 15 is composed of two groups of support columns 151 fixedly arranged at the ends of the fastening frame 13, a pressure rod 152 hinged between the two groups of support columns 151, a connecting rod 153 hinged at the bottom of the pressure rod 152, and a clamping rod 154 arranged at the bottom of the connecting rod 153. The ends of the support columns 151 are provided with hinge holes, which are hinged to the hinge holes on both sides of the pressure rod 152; and the pressure rod 152 is composed of L-shaped rods on both sides and an intermediate connecting plate, which is convenient for driving the buckles 14 on both sides to move at the same time. The connecting rod 153 is hinged in another hinge hole of the pressure rod 152, and is hinged to the clamping rod 154 at its bottom. The clamping rod 154 is fixedly connected to the through hole of the connecting frame 1421 and is fixedly connected to it.

[0064] When in use, the operator first places the cable 2 to be connected between the fastening end 121 and the lower end surface 1112. At this time, the lower end surface 1112 is preliminarily fixed to the cable 2 under the pressure of the spring 113 between the upper end surface 1111 and the connection end 123.

[0065] For the copper wire cable 2 whose outer insulation has been stripped, there is no need to use the additional stopper 15 for puncture. The cable can be directly and reliably electrically connected by preliminary fixation.

[0066] When the cable 2 is not peeled, the operator manually drives the pressure rod 152 so that the pressure rod 152 drives the clamping rods 154 on both sides to move downward. As the clamping rod 154 descends, the connecting frame 1421 and the extension arm 1422 sink accordingly, thereby driving the support plate 1121 and the positioning rod 112 thereon to descend together. The descent of the positioning rod 112 ultimately acts on the lower end surface 1112, and applies pressure to the cable 2 through the lower end surface 1112. This pressure forces the cable 2 to press downward on the puncture point 1621 on the wire seat 162, thereby penetrating the outer skin of the cable and directly contacting the internal copper wire, ensuring the conductive performance. Among them, the cable itself is made to descend and contact the puncture end, rather than allowing the puncture end to actively move and act on the cable, so that the mechanical stress borne by the cable itself is more uniform. On the contrary, if the puncture end actively moves and acts on the cable, it may cause local stress concentration, especially around the puncture point, which may damage the conductor or insulation layer inside the cable and prevent the copper wire from being penetrated.

[0067] In summary, this device allows wiring operations without power outages, reduces the need for power outages, improves work efficiency and reduces safety risks. In addition, operators do not need to use blades or other tools to remove the insulating protective layer on the outside of the cable, and can directly place the cable between the fastening end and the lower end face to achieve initial fixation. For unstripped cables, the puncture end is manually driven to penetrate the outer sheath of the cable and contact the internal copper wire, which greatly simplifies the wiring steps and shortens the working time. At the same time, through the puncture connection, the resistance of the joint can be reduced, the heat generated when the current passes through can be reduced, the occurrence of current adhesion can be prevented, and subsequent inspection and maintenance can be facilitated. It is also easy to disassemble and reinstall, which facilitates the replacement of the cable after wiring to the next wiring point, simplifies the maintenance process, and reduces maintenance costs and technical difficulties.

[0068] Reference Figure 2~Figure 7 , which is the second embodiment of the present invention, is different from the first embodiment in that it also includes a snap-fit ​​member 14 including a top block 141 arranged at the bottom of the fastening frame 13, and two sets of driving plates 142 slidably arranged on both sides of the top block 141.

[0069] Furthermore, the extension arm 1422 includes a clamping groove 14221 fixedly clamped with the support plate 1121, and a hook plate 14222 disposed at the bottom of the extension arm 1422;

[0070] The top block 141 includes lifting blocks 1411 on both sides thereof, and clamping blocks 1412 arranged on both sides thereof;

[0071] The bottom of the fastening frame 13 is provided with a receiving groove 131 , in which the top block 141 slides.

[0072] It should be noted that a receiving groove 131 is provided at the bottom of the fastening frame 13, and a group of top blocks 141 are slidably connected in the receiving groove 131, and the top block 141 is composed of two groups of lifting blocks 1411 on both sides, and the clamping blocks 1412 on both sides. A group of hook plates 14222 are convexly provided at the bottom of the extension arm 1422. When the limiter 15 descends to the puncture 1621 to contact the copper wire in the cable 2, the position of the hook plate 14222 is lower than the position of the clamping block 1412, ensuring that when the hook plate 14222 moves upward with the extension arm 1422, it moves slower than the support plate 1121 in the upward movement.

[0073] Preferably, the lifting block 1411 can extend through the avoidance groove 1211 at the bottom of the fastening end 121 to lift the cable 2 so that the cable 2 is no longer in contact with the puncture 1621, thereby achieving disconnection of the current and ensuring the safety of the operator.

[0074] The other structures are the same as those in Example 1.

[0075] When in use, the cable 2 to be connected is placed between the fastening end 121 and the lower end face 1112. At this time, the lower end face 1112 preliminarily fixes the cable 2 under the pressure of the spring 113. The operator manually drives the pressure rod 152, so that the pressure rod 152 drives the clamping rods 154 on both sides to move downward, thereby pushing the driving plate 142 and its extension arm 1422 to descend. As the driving plate 142 sinks, the support plate 1121 and the positioning rod 112 fall accordingly, and finally act on the lower end face 1112, and apply pressure to the cable 2 through the lower end face 1112, so that it contacts and penetrates the puncture 1621 on the wire seat 162, and directly contacts the internal copper wire to ensure the conductive performance. The pressure rod 152 has a self-locking mechanism. When the puncture 1621 contacts the copper wire, the spring 113 is stretched, and the force generated by it will indirectly act on the pressure rod 152, promoting its self-locking effect and avoiding the pressure rod 152 from accidentally touching and disconnecting.

[0076] When it is necessary to disconnect the connection, the pressure rod 152 is driven in the reverse direction, the driving plate 142 will rise, and the support plate 1121 and the positioning rod 112 will rise accordingly, and finally act on the lower end surface 1112, and the pressure on the cable 2 is released through the lower end surface 1112. When the limiter 15 descends to the point where the puncture 1621 contacts the copper wire in the cable 2, the position of the hook plate 14222 is lower than the position of the clamping block 1412. This will cause the hook plate 14222 to move upward with the extension arm 1422, one step slower than the upward movement of the support plate 1121. It is ensured that the cable 2 will be lifted up only after the lower end surface 1112 is completely away from the cable 2. This design effectively prevents the problem of cable 2 being difficult to separate due to current adhesion to the connection point, and ensures that the cable can be easily and safely detached from the connection point.

[0077] In summary, the device achieves safe wiring without cutting off the power supply through the connection unit, simplifies the stripping and fixing steps, reduces the risk of damage to the cable due to mechanical stress, and ensures stable electrical connection and low-resistance contact through multiple sets of arc-shaped puncture points, reducing the risk of heat generation and current adhesion, while facilitating subsequent maintenance and cable replacement, significantly improving the efficiency, safety and reliability of wiring work.
