Description

Technical Field

[0001] The utility model relates to the technical field of equipment detection, in particular to a quick wiring device. Background Art

[0002] Air conditioner production requires multiple tests, especially the need to power up the unit before testing. Currently, most commercial air conditioner production and testing uses a "terminal block screw-locked U-shaped terminal" method for electrical connections. This presents the following issues: First, the terminal block and U-shaped terminal have numerous connection points, and the terminal block screws must be repeatedly removed and installed using a torque screwdriver, which is inefficient. Second, the U-shaped terminal connected to the terminal block is prone to deformation and fracture, which can easily lead to poor contact and affect the current carrying capacity and stability of the conductor. This results in both labor and tool costs, and is not conducive to automated docking. Utility Model Content

[0003] The purpose of the utility model is to provide a quick wiring device, which has high current carrying capacity and high fault tolerance, and can conveniently complete docking without the need for tools, thereby greatly saving manpower and tool costs and improving labor efficiency.

[0004] To achieve the above-mentioned objectives, the utility model provides a quick wiring device, including: a first claw assembly, the first claw assembly is provided with a first gripping portion and a first clamping portion; a second claw assembly, the first claw assembly is hinged to the second claw assembly, the second claw assembly is provided with a second gripping portion and a second clamping portion, the second claw assembly can rotate between a clamping position and a separation position relative to the first claw assembly, when in the clamping position, the first clamping portion and the second clamping portion form a positioning groove, the first gripping portion and the second gripping portion are both made of insulating material, and the first clamping portion and the second clamping portion are both made of conductive material; a first elastic member, the first elastic member forces the first clamping portion and the second clamping portion to remain in the clamping position; an electrical connector, the electrical connector is hinged to the first clamping portion, the first end of the electrical connector is provided with an electrical connector, and the electrical connector extends axially along the positioning groove; a second elastic member, the second elastic member is arranged at the second end of the electrical connector and forces at least a portion of the electrical connector to extend into the positioning groove.

[0005] As can be seen from the above scheme, when testing equipment such as air conditioners, the wires are electrically connected to the first clamping portion or the second clamping portion. The operator grasps the first and second clamping portions by hand and applies a gripping force to force the two together. At this time, the first elastic member compresses and accumulates force, and the first and second clamping portions separate. Then, the quick wiring device is clamped to the screw on the terminal block. After loosening the first and second clamping portions, the quick wiring device is tightly locked to the terminal block. At this time, the first and second clamping portions confine the head of the screw within the positioning groove, and the electrical connection portion abuts the top of the screw. The first and second clamping portions radially limit and electrically contact the screw, and the electrical connection portion electrically contacts the screw axially. Through a three-point contact structure, contact is made at different positions of the terminal block screw, increasing the contact area and the current-carrying area. At the same time, the fault tolerance and stability of the docking are improved, and the current-carrying capacity of the docking surface is greatly improved. In addition, the first clamping portion and the second clamping portion cooperate in the radial direction to fix and lock the heads of the screws on the terminal board, and the docking can be completed conveniently without the need for tools, which greatly saves manpower and tool costs and improves labor efficiency.

[0006] A preferred solution is that the first claw assembly includes a first insulating shell and a first claw body, a first claw mounting groove is opened in the first insulating shell, the first claw body is installed in the first claw mounting groove, the first gripping part is located at the top end of the first insulating shell, and the first clamping part is located at the bottom end of the first claw body.

[0007] A further solution is that the second claw assembly includes a second insulating shell and a second claw body, a second claw mounting groove is opened in the second insulating shell, the second claw body is installed in the second claw mounting groove, the second gripping part is located at the top of the second insulating shell, and the second clamping part is located at the bottom end of the second claw body.

[0008] It can be seen that wrapping the claw body made of conductive material with an insulating shell can improve the safety of use.

[0009] A further solution is that the first claw body and the second claw body are hinged through a claw hinge shaft, the first elastic member is a torsion spring, the spring coil of the torsion spring is mounted on the claw hinge shaft, the first torsion arm of the torsion spring abuts against the first claw body, and the second torsion arm of the torsion spring abuts against the second claw body.

[0010] It can be seen that the provision of the torsion spring allows the quick connection device to remain in the clamping position after the operator removes the external force, thereby improving the stability of the electrical connection.

[0011] A further solution is that the quick wiring device also includes a first fixing member and a second fixing member, the first insulating shell and the first claw body are fixedly connected by the first fixing member, and the second insulating shell and the second claw body are fixedly connected by the second fixing member; the extension directions of the first fixing member and the second fixing member are both set at an angle to the axial direction of the positioning groove.

[0012] This shows that the stability of the fixed connection between the insulating shell and the corresponding claw body is ensured.

[0013] A preferred solution is that a shell wire passing hole is provided on the first insulating shell, and a claw wire passing hole connected to the shell wire passing hole is provided on the first claw body; the quick wiring device also includes a wire locking piece, which is installed on the first claw body, and the wire locking end of the wire locking piece extends into the claw wire passing hole.

[0014] It can be seen that when in use, the end of the wire passes through the wire hole of the shell and then extends into the wire hole of the clamping claw, and then the wire is pressed by the wire locking piece to achieve electrical connection between the wire and the first clamping claw body.

[0015] A further solution is that the extending direction of the thread locking member is parallel to the axial direction of the positioning groove.

[0016] This shows that reasonable layout can avoid increasing the size of the device and the cost.

[0017] A preferred solution is that an electrical connector installation slot is further provided in the first clamping portion, and the second elastic member and the electrical connector are both arranged in the electrical connector installation slot.

[0018] A preferred solution is that the notch of the positioning groove is provided with a guiding inclined surface, and the guiding inclined surface is inclined in a direction away from the positioning groove.

[0019] This makes it easier for the guide screw to enter the positioning groove more smoothly.

[0020] A preferred solution is that the positioning groove is cylindrical, with a screw head position in the positioning groove, and a screw slot position on the side of the screw head position facing the electrical connection part; in the clamping position, the electrical connection part extends into the screw slot; the cross-sectional size of the screw head position is larger than the size of the notch of the positioning groove.

[0021] It can be seen that the positioning groove is cylindrical and is designed according to the size of the screw head on the terminal block. In this way, during the docking process between the quick wiring device and the screw, the two opposite arc-shaped groove walls fix and lock the head of the screw on the terminal block, ensuring that the quick wiring device and the terminal block are firmly fixed, improving the docking accuracy and stability. At the same time, the contact between the arc-shaped groove wall and the screw head further increases the contact area, thereby increasing the current-carrying area.

[0022] A preferred solution is that the diameter of the electrical connection portion gradually decreases from an end away from the notch of the positioning groove to an end close to the notch.

[0023] It can be seen that the diameter of the free end of the electrical connection part is small, which facilitates the positioning of the electrical connection part relative to the screw, further improving the compatibility of the quick wiring device. At the same time, the structure is designed according to the size of the cross slot of the screw head of the terminal block, and can be pushed into the cross slot of the screw head during docking, thereby increasing the contact area and improving the current carrying capacity.

[0040] See also Figures 1 to 6 The quick connection device in this embodiment includes a first claw assembly 1, a second claw assembly 2, a first elastic member 3, an electrical connector 5, a second elastic member 4, a first fixing member 6, a second fixing member 7, and a wire locking member 8. In this embodiment, the first elastic member 3 is a torsion spring, the second elastic member is a spring, and the first fixing member 6, the second fixing member 7, and the wire locking member 8 are all screws.

[0041] The first jaw assembly 1 is hinged to the second jaw assembly 2 , and the second jaw assembly 2 is rotatable relative to the first jaw assembly 1 between a clamping position and a separation position.

[0042] The first claw assembly 1 includes a first insulating shell 11 and a first claw body 12. The first insulating shell 11 and the first claw body 12 are fixedly connected by a first fixing member 6. A first claw mounting groove 111 is provided in the first insulating shell 11. The first claw body 12 is installed in the first claw mounting groove 111. A first gripping portion 112 is provided at the top end of the first insulating shell 11, and a first clamping portion 121 is provided at the bottom end of the first claw body 12.

[0043] The second jaw assembly 2 includes a second insulating housing 21 and a second jaw body 22, which are fixedly connected by a second fixing member 7. A second jaw mounting slot 211 is defined within the second insulating housing 21, into which the second jaw body 22 is mounted. A second gripping portion 212 is provided at the top of the second insulating housing 21, and a second clamping portion 221 is provided at the bottom of the second jaw body 22. When in the clamped position, the first clamping portion 121 and the second clamping portion 221 form a positioning slot 20. The first fixing member 6 and the second fixing member 7 extend at an angle to the axial direction of the positioning slot 20. Preferably, in this embodiment, the first fixing member 6 and the second fixing member 7 extend perpendicular to the axial direction of the positioning slot 20. Both the first insulating housing 11 and the second insulating housing 21 are made of insulating material, while the first jaw body 12, the second jaw body 22, and the electrical connector 5 are made of conductive material. Encasing the conductive jaw body in the insulating housing enhances safety.

[0044] See also Figures 5 to 8 The first insulating housing 11 defines a housing wire hole 113, and the first claw body 12 defines a claw wire hole 122 that is opposite and connected to the housing wire hole 113. The wire locking member 8 is mounted on the first claw body 12, with the wire locking end of the wire locking member 8 extending into the claw wire hole 122. The wire locking member 8 extends in a direction parallel to the axial direction of the positioning slot 20. During use, the end of the wire passes through the housing wire hole 113 and then into the claw wire hole 122. The wire is then compressed by the wire locking member 8, achieving an electrical connection between the wire and the first claw body 12.

[0045] The first claw body 12 and the second claw body 22 are hingedly connected via a claw hinge shaft 9. The first elastic member 3 is a torsion spring, the coil 31 of which is mounted on the claw hinge shaft 9. The first torsion arm 32 of the torsion spring abuts against the first claw body 12, and the second torsion arm 33 of the torsion spring abuts against the second claw body 22. The first elastic member 3 forces the first clamping portion 121 and the second clamping portion 221 to remain in the clamped position. The provision of the torsion spring facilitates maintaining the quick connection device in the clamped position even after the operator removes the external force, thereby improving the stability of the electrical connection.

[0046] The first clamping portion 121 also includes a mounting slot 123, within which the second elastic member 4 and the electrical connector 5 are disposed. The electrical connector 5 is hingedly connected to the first clamping portion 121 via a connector hinge 52. The first end of the electrical connector 5 includes an electrical connector 51, which extends axially along the positioning slot 20. The second elastic member 4 is disposed at the second end of the electrical connector 5 and forces at least a portion of the electrical connector 51 to extend into the positioning slot 20. The diameter of the electrical connector 51 gradually decreases from the end away from the notch 201 of the positioning slot 20 to the end closer to the notch 201. The free end of the electrical connector 51 has a smaller diameter, facilitating positioning of the electrical connector 51 relative to the screw 10 and further improving the compatibility of the quick-connect device.

[0047] The positioning groove 20 is cylindrical and contains a screw head position 203. The side of the screw head position 203 facing the electrical connection portion 51 has a screw slot 202. When the quick-connect device is clamped onto the screw 10 of the terminal block 100, the head 101 of the screw 10 is located at the screw head position 203, and the screw slot 102 of the screw 10 is located at the screw slot 202. In the clamped position, the electrical connection portion 51 extends into the screw slot 202. The cross-sectional dimensions of the screw head position 203 are larger than the dimensions of the notch 201 of the positioning groove 20. In this embodiment, the cross-sectional diameter of the screw head position 203 is larger than the diameter of the notch 201 of the positioning groove 20, thereby preventing the quick-connect device from separating from the screw 10 of the terminal block 100. The notch 201 of the positioning groove 20 is provided with a guide slope 204, which is inclined away from the positioning groove 20 to facilitate smoother entry of the screw 10 into the positioning groove 20. The positioning groove 20 is cylindrical. In this way, during the docking process between the quick wiring device and the screw 10, the two opposite arc-shaped groove walls fix and lock the head 101 of the screw 10 on the terminal block 100. The contact between the arc-shaped groove wall and the head 101 of the screw 10 further increases the contact area, thereby improving the current-carrying area.

[0048] When testing an air conditioner or other equipment, connect the wires to the first clamping portion 121 or the second clamping portion 221. Figure 6 、 Figure 9 and Figure 10The operator holds the first gripping portion 112 and the second gripping portion 212 by hand and applies a gripping force to force the two together. At this time, the first elastic member 3 is compressed and stored. Based on the principle of leverage, the first clamping portion 121 and the second clamping portion 221 are separated. Then, the positioning groove 20 is aligned with the screw 10 on the terminal block 100 and moved downward until the bottom of the second clamping portion 221 contacts the conductive sheet of the terminal block 100. Then, after releasing the first gripping portion 112 and the second gripping portion 212, the quick wiring device is tightly locked on the terminal block 100. At this time, the first clamping portion 121 and the second clamping portion 221 restrict the head 101 of the screw 10 in the positioning groove 20. Under the action of the restoring force of the first elastic member 3, the two are kept in the separated position. At the same time, the electrical connection portion 51 abuts against the screw groove 102 of the head 101 of the screw 10 under the action of the second elastic member 4, thereby achieving docking with the terminal block 100. If disassembly is required, the first clamping portion 121 and the second clamping portion 221 need only be pressed to separate the first clamping portion 121 and the second clamping portion 221 , and then the quick connection device is separated from the connection board 100 to complete the disassembly.

[0049] As can be seen above, the first and second clamping portions radially limit and electrically contact the screw, while the electrical connector makes axial electrical contact with the screw. This three-point contact structure allows for contact at different locations on the terminal block screw, increasing the contact area and current-carrying area. This also improves the tolerance and stability of the docking connection, significantly increasing the current-carrying capacity of the docking interface. Furthermore, the first and second clamping portions radially secure and lock the screw heads on the terminal block, enabling convenient tool-free docking, significantly saving labor and tool costs and improving labor efficiency.

[0050] In addition, the second elastic member can also be a tension spring, and the tension spring is located between the top of the electrical connector and the top wall of the mounting groove. The second elastic member can also be made of an elastic material such as rubber. The second insulating shell and the second claw body can also be integrally formed by injection molding, so there is no need to set a screw as a second fixing member. The area of ​​the first claw body covered by the first insulating shell and the area of ​​the second claw body covered by the second insulating shell can be changed as needed. The cross-section of the positioning groove can also be non-circular. The above changes can also achieve the purpose of the utility model.

[0051] Finally, it should be emphasized that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various changes and modifications. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
