DETAILED DESCRIPTION
[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0037] Embodiment 1: This embodiment is intended to promote the solution of the connection method between the terminal and the wire. Usually, the operator inserts the wire into the terminal. When installing a large number of wires, the operator needs to insert the wires into the terminal one by one. However, due to the large number of wires to be connected, it is troublesome to connect them one by one, which increases the complexity and difficulty of the installation process. In addition, the problem of inconsistent wire connection length may occur during manual installation of the wire. Please refer to Figure 1 - Fig. 9 A conductive connection device for wiring harness terminals of a power distribution cabinet, comprising a terminal body 210 and a bottom plate 110 integrally installed on the bottom side of the terminal body 210, a wiring board 111 for unified wiring is installed on the bottom plate 110, a spring sheet 220 is installed inside the terminal body 210, a through hole 112 for clamping a wire is opened on the wiring board 111, a clamping seat 120 for clamping a wire is installed inside the through hole 112, a first winding disk 134 for tightening the spring sheet 220 is rotatably installed on the terminal body 210, and a winding mechanism 130 for controlling the rotation of the first winding disk 134 is rotatably installed on the terminal body 210;
[0038] The winding mechanism 130 includes a driving gear 131 rotatably mounted on the side of the terminal body 210, a rotating shaft 132 coaxially mounted on the side of the driving gear 131, and a driven shaft 133 mounted inside the terminal body 210. The driven shaft 133 is configured as a hollow shaft, the rotating shaft 132 is loosely fitted inside the driven shaft 133, and the first winding disk 134 is loosely fitted on the rotating shaft 132.
[0039] The clamping seat 120 includes a first clamping column 121 and a second clamping column 122, which are respectively located inside the through hole 112. A pressing groove 123 is provided on the inner wall of the terminal block 111. A sliding plate 124 is slidably installed inside the pressing groove 123. A connecting rod 125 is installed on the bottom side of the sliding plate 124. The connecting rod 125 is connected to the first clamping column 121. A pressing spring 126 is movably sleeved on the surface of the connecting rod 125. The first clamping column 121 and the second clamping column 122 have the same specifications.
[0040] The bottom plate 110 is symmetrically provided with sliding grooves 113 , and the bottom side of the wiring board 111 is symmetrically provided with sliding blocks 114 , which are slidably matched with the sliding grooves 113 .
[0041] See Figure 1 , Figure 2 and Figure 3In the specific implementation, the operator manually puts the wire into the perforation 112, and uses the cooperation of the first clamping column 121 and the second clamping column 122 to clamp the wire, so that the wire is fixed. After several wires are fixed, the terminal block 111 is manually pushed, and through the cooperation of the slider 114 and the slide groove 113, the terminal block 111 can be fitted with the terminal body 210, and the wire is inserted into the terminal body 210, so that the wires are connected to the terminal body 210 in batches, reducing the labor cost and improving the wiring efficiency.
[0042] A control board 140 for uniformly controlling the wiring length is movably mounted on the bottom plate 110, a support shaft 141 is mounted on the bottom plate 110, a torsion spring 142 is mounted between the control board 140 and the support shaft 141, a through slot 143 is provided on the wiring board 111 for the control board 140 to pass through, and a control rod 144 for pushing the control board 140 is mounted on the side of the wiring board 111; when the wiring board 111 slides, the control rod 144 pushes the control board 140, the control board 140 changes direction, and the through slot 143 moves from the upper side of the control board 140.
[0043] The terminal body 210 is provided with a circular groove 230 for the control rod 144 to be inserted into.
[0044] See Figure 1 , Figure 2 , Figure 3 and Fig. 9 In a specific implementation, when the operator inserts the wire into the through hole 112, the end of the wire will touch the control board 140 through the setting of the control board 140 during the insertion of the wire. When the wire touches the control board 140, it serves as a guide for the insertion distance of the wire, thereby reducing the possibility that the wire is inserted into the terminal body 210 at different lengths during the wiring process, thereby affecting the wiring effect;
[0045] Moreover, through the cooperation of the control rod 144, when the operator pushes the terminal block 111, the control rod 144 resists the control board 140, so that during the movement of the terminal block 111, the control board 140 can achieve the reverse direction by using the cooperation of the torsion spring 142 and the support shaft 141. Therefore, as the terminal block 111 continues to move, the through slot 143 moves from the upper side of the control board 140, so that the terminal block 111 can smoothly contact the terminal body 210.
[0046] In this embodiment: by setting the wiring board 111, and setting the through hole 112, the first clamping column 121 and the second clamping column 122 on the wiring board 111, when the operator inserts the lead into the through hole 112, the first clamping column 121 and the second clamping column 122 cooperate to clamp the wire, thereby fixing the wire and reducing the possibility of wire shaking; after fixing a number of wires, the operator pushes the wiring board 111 so that the wiring board 111 can fit with the terminal body 210, and the wires are plugged into the terminal body 210, thereby realizing batch connection of the wires with the terminal body 210, reducing the labor cost and improving the wiring efficiency;
[0047] Furthermore, through the setting of the control board 140, when the operator is inserting the wire, the end of the wire will touch the control board 140. Therefore, the control board 140 is used as a boundary to guide the wire to contact the control board 140, thereby uniformly controlling the wire connection distance, reducing the possibility of the operator inserting the wires of different lengths into the terminal body 210 during the wiring process, thereby improving the wiring effect.
[0048] Embodiment 2: This embodiment is intended to promote the solution of the problem that a spring sheet is usually installed inside the terminal body. The spring sheet can provide sufficient pressure to ensure that the wire is firmly fixed inside the terminal body to prevent it from loosening or falling off during vibration or movement. However, during batch wiring, the spring may hinder the wire from entering the terminal body, affecting the wiring. This embodiment is an improvement made on the basis of Embodiment 1. For details, please refer to Figure 1 - Fig. 9 A driving rack 150 is installed on the side of the wiring board 111, and the driving rack 150 is meshed with the driving gear 131. An air storage chamber 151 is opened on the surface of the rotating shaft 132. A first piston block 152 is slidably installed at one end of the air storage chamber 151, and a second piston block 153 is slidably installed at the other end of the air storage chamber 151. Compression springs 154 are installed inside the first piston block 152 and the air storage chamber 151. A plurality of elastic blocks 155 are installed on the inner wall of the first winding disk 134, and the plurality of elastic blocks 155 are installed on the inner wall of the first winding disk 134 in a ring array.
[0049] The driven shaft 133 has an extrusion groove 160 on its surface. The extrusion groove 160 is an arc-shaped groove. A first winding rope 161 is installed on the surface of the first winding disc 134. The first winding rope 161 is connected to the end of the spring sheet 220.
[0050] When the driving gear 131 rotates, the first piston block 152 is engaged between the plurality of elastic blocks 155, and the first winding disk 134 rotates along with the driving gear 131. At this time, the spring sheet 220 is in a tightened state.
[0051] When the driving gear 131 rotates one circle, the end of the second piston block 153 slides into the extrusion groove 160, the first piston block 152 is disengaged from the plurality of elastic blocks 155, and the spring sheet 220 is in an expanded state.
[0052] See Figure 4 , Figure 5 and Figure 6 In a specific implementation, when the wiring board 111 moves, the driving rack 150 installed on the side follows the movement, and engages with the driving gear 131 during the movement to rotate it. When the driving gear 131 rotates, it drives the rotating shaft 132 to rotate. Since the first winding disk 134 is arranged on the surface of the rotating shaft 132, and the first piston block 152 is engaged with a plurality of elastic blocks 155, the first winding disk 134 is restricted to rotate with the rotating shaft 132, so that the first winding disk 134 reels the first winding rope 161 during the rotation process, and compresses the spring sheet 220 during the reeling process of the first reel 161, so that the spring sheet 220 is tightened, so that a plurality of wires can smoothly reach the inside of the terminal body 210 to complete the wiring;
[0053] It should be noted that the compression spring 154 is configured as a tension spring.
[0054] Moreover, as the terminal block 111 continues to move, the rotating shaft 132 rotates, and the second piston block 153 is located inside the extrusion groove 160, so the second piston block 153 loses resistance, and at the same time, the compression spring 154 drives the first piston block 152 to retract into the air storage chamber 151, and squeezes the gas inside the air storage chamber 151, so that the second piston block 153 reaches the extrusion groove 160, which also means that the first piston block 152 is disengaged from the engagement with the elastic block 155, and the first winding disk 134 is driven to rotate by the spring sheet 220's own elastic force, so that the spring sheet 220 is changed from a tightened state to an expanded state, so that the wire is fixed again, and at this time the terminal block 111 is in contact with the terminal body 210.
[0055] The surface of the terminal block 111 is symmetrically provided with grooves 170, which are communicated with the pressing groove 123, and the first extrusion block 162 and the second extrusion block 163 are symmetrically installed on the terminal body 210; when the terminal block 111 moves, the first extrusion block 162 and the second extrusion block 163 are respectively engaged with the grooves 170, and the first extrusion block 162 and the second extrusion block 163 respectively press the sliding plate 124, and the first clamping column 121 and the second clamping column 122 are close to each other, so as to strengthen the fixation of the wire.
[0056] See Figure 1 , Figure 4 , Figure 5 and Figure 6In a specific implementation, when the terminal block 111 approaches the terminal body 210, the second extrusion block 163 and the first extrusion block 162 are respectively inserted into the groove 170. Since the second extrusion block 163 and the first extrusion block 162 have a certain thickness, the first extrusion block 162 and the second extrusion block 163 press the sliding plate 124 respectively, so the first clamping column 121 and the second clamping column 122 are close to each other, further strengthening the fixation of the wire and improving the wiring effect.
[0057] In this embodiment: during the movement of the wiring board 111, the rotation of the rotating shaft 132 is realized by the cooperation of the driving gear 131 and the driving rack 150, and at the same time, the cooperation of the first piston block 152, the air storage chamber 151, the second piston block 153 and the plurality of elastic blocks 155 is utilized to make the first piston block 152 engage between the plurality of elastic blocks 155, so that the first winding disk 134 is restricted to rotate with the rotating shaft 132, and during the rotation process, the first winding rope 161 is utilized to pull and compress the spring sheet 220, so that the plurality of wires can smoothly reach the inside of the terminal body 210 to complete the wiring, and improve the wiring effect;
[0058] Moreover, by providing an extrusion groove 160 in the inner wall of the driven shaft 133, when the rotating shaft 132 rotates one circle, the second piston block 153 reaches the inside of the extrusion groove 160, so the second piston block 153 loses resistance, and at the same time, the cooperation of the compression spring 154 and the first piston block 152 allows the second piston block 153 to reach the inside of the extrusion groove 160, and at the same time, the first piston block 152 is disengaged from the elastic block 155, and the elastic force of the spring sheet 220 drives the first winding disk 134 to rotate, so that the spring sheet 220 is changed from a tightened state to an unfolded state, so that the wire is fixed again, thereby improving the wiring efficiency;
[0059] At the same time, when the terminal block 111 approaches the terminal body 210, the first extrusion block 162 and the second extrusion block 163 cooperate with the groove 170, so that the first extrusion block 162 and the second extrusion block 163 press the sliding plate 124 respectively, so that the first clamping column 121 and the second clamping column 122 are close to each other, further strengthening the fixation of the wire and improving the wiring effect.
[0060] Embodiment 3: This embodiment is intended to solve the problem that during the wiring process of the terminal body, wires of different thicknesses may be plugged in, but the clamping force of wires of different thicknesses is usually the same. Therefore, after the wiring is completed, if the elastic force of the spring sheet and the clamping seat does not change, the thicker wire will be squeezed to a deeper degree, resulting in the rupture of the insulation layer on the outside of the wire. This embodiment is an improvement made on the basis of embodiment 2. For details, please refer to Figure 1 - Fig. 9 A knob 180 for adjusting the clamping force is rotatably installed on the terminal body 210, and a second winding disk 181 and a third winding disk 182 are installed on the rotating shaft of the knob 180. A second winding rope 183 is installed on the surface of the second winding disk 181, and the second winding rope 183 is connected to the end of the spring sheet 220.
[0061] It should be noted that the knob 180 is configured as a self-locking knob 180. The self-locking knob is usually composed of a knob body, a locking mechanism, and a knob base. The self-locking knob can be automatically locked after being rotated to the set position to prevent accidental movement. The self-locking knob is a common device, and its specific model, working principle and usage are well known to technicians in this field, so they will not be elaborated here.
[0062] The terminal body 210 is provided with a sliding groove 190, and the first extrusion block 162 is slidably installed inside the sliding groove 190. A release spring 191 is installed between the sliding groove 190 and the first extrusion block 162, and a third winding rope 192 is installed on the surface of the third winding disk 182, and the third winding rope 192 is connected to the first extrusion block 162.
[0063] See Figure 8 During the specific implementation, when the operator manually twists the knob 180, the rotating shaft of the knob 180 will drive the second winding disc 181 and the third winding disc 182 to rotate. During the rotation of the second winding disc 181 and the third winding disc 182, the second winding rope 183 and the third winding rope 192 are respectively wound up, so that the originally unfolded spring sheet 220 and the release spring 191 are tightened, thereby reducing the clamping force on the thicker wire. By adjusting the clamping force of the spring sheet 220 and the release spring 191, it is relatively easy to adapt to wires of different thicknesses, making the installation process simpler and faster.
[0064] In the present embodiment: through the cooperation between the second winding drum 181 and the third winding drum 182 and the second winding rope 183 and the third winding rope 192, the second winding rope 183 and the third winding rope 192 are wound up in the process of twisting the knob 180, so that the originally unfolded spring sheet 220 and the release spring 191 are tightened, thereby reducing the clamping force for thicker wires. By adjusting the clamping force of the spring sheet 220 and the release spring 191, the terminal body 210 can better adapt to wires of different thicknesses. For thicker wires, the clamping force can be reduced to avoid rupture of the insulation layer; for thinner wires, sufficient clamping force can also be maintained to ensure the firmness of the connection.
