Description

Technical Field

[0001] The utility model relates to the technical field of wiring devices, in particular to a cable wiring device for electrical equipment and the electrical equipment thereof. Background Art

[0002] In the technical field of electrical equipment such as motors and generators, it is usually necessary to lead out the copper wire of the winding to the outside of the motor and connect it to a controller for use. The winding lead-out wire of the electrical equipment extends along the axis direction of the winding, while the external lead-out wire connected to the electrical equipment is perpendicular to the axis direction of the winding of the electrical equipment, and the two are installed at a 90° angle. The two lead-out wires need to be installed in parallel when using traditional crimp terminals, resulting in a large installation space requirement, causing waste of cost and space. Moreover, when a 90° bending installation is required, the lead-out wire needs to be bent. Since the lead-out wire itself has a certain hardness, a certain bending space is required, which is very disadvantageous for the installation requirements in a small space. At the same time, if the lead-out wire is forcibly bent, the cable core wire of the lead-out wire may be broken, resulting in damage and failure. Further, if some connectors using the elastic principle are used, there are disadvantages in reliability. At the same time, in order to ensure the size of the elastic metal, the processing requirements for such connectors are relatively high, and the cost of this solution increases significantly.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0029] The purpose of the present utility model is to provide a cable wiring device for electrical equipment and the electrical equipment thereof, so as to solve the problems existing in the above-mentioned prior art, and make the connection of the winding lead-out wire and the external lead-out wire occupy less space and have high reliability.

[0030] In order to make the above-mentioned objects, features and advantages of the present utility model more obvious and understandable, the present utility model will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0031] As Figures 1 to 9 shown, this embodiment provides a cable wiring device for electrical equipment, including a first crimping terminal 1 extending along the winding axis direction of the electrical equipment. Preferably, the entire first crimping terminal 1 is made of copper material;

[0032] The winding lead-out wire 2 of the winding is led out along its axis direction. One end of the first crimping terminal 1 is crimped on the winding lead-out wire 2. The external lead-out wire 3 matched with the electrical equipment extends along the direction perpendicular to the winding axis. The other end of the first crimping terminal 1 is detachably connected to the external lead-out wire 3, so as to connect the vertically distributed winding lead-out wire 2 and the external lead-out wire 3 through the first crimping terminal 1, without bending the winding lead-out wire 2 or the external lead-out wire 3, avoiding the problem of the core wire of the cable being broken due to forced bending, and making the connection of the winding lead-out wire 2 and the external lead-out wire 3 occupy less space and have high reliability.

[0033] As a preferred embodiment of the present utility model, a voltage-conducting pipe 5 is provided at one end of the first crimping terminal 1 connected to the winding lead-out wire 2. The voltage-conducting pipe 5 extends in the same direction as the first crimping terminal 1 and is sleeved at the end position of the winding lead-out wire 2. By sleeving the voltage-conducting pipe 5 on the winding lead-out wire 2 and crimping it with the winding lead-out wire 2, the stability of the connection between the first crimping terminal 1 and the winding lead-out wire 2 is ensured. Specifically, the voltage-conducting pipe 5 is a circular ring structure with a fixed wall thickness and a certain length. After sleeving the voltage-conducting pipe 5 on the winding lead-out wire 2, the fixed connection between the voltage-conducting pipe 5 and the winding lead-out wire 2 can be completed by means of cold pressing or resistance welding. And preferably, the voltage-conducting pipe 5 and the first crimping terminal 1 are integrally formed to ensure the firmness of the connection between the voltage-conducting pipe 5 and the first crimping terminal 1 and reduce the resistance loss.

[0034] Further, on one end of the first crimping terminal 1 connected to the external lead wire 3, a conductive blind hole 6 is formed on its end face. The conductive blind hole 6 extends in the same direction as the first crimping terminal 1, and a conductive plug-in member 8 is detachably inserted into the conductive blind hole 6. The external lead wire 3 is crimped between the conductive blind hole 6 and the conductive plug-in member 8. By providing the conductive blind hole 6 and the conductive plug-in member 8, during the process of their plug-in cooperation, the external lead wire 3 is squeezed between the conductive blind hole 6 and the conductive plug-in member 8 to complete the connection between the first crimping terminal 1 and the external lead wire 3. Through the cooperation of the conductive blind hole 6 and the conductive plug-in member 8, the work of connecting the external lead wire 3 becomes simpler.

[0035] Preferably, the conductive blind hole 6 is in the shape of a threaded conductive blind hole 6 to act as a nut, and the conductive plug-in member 8 is in the shape of a bolt threadedly connected in the conductive blind hole 6. By threading the conductive plug-in member 8 into the conductive blind hole 6, the firmness of the connection between the conductive plug-in member 8 and the conductive blind hole 6 for connecting the external lead wire 3 is improved, ensuring the reliability during the installation process.

[0036] Further, a nut is provided at the end of the conductive plug-in member 8 that is not inserted into the conductive blind hole 6. The external lead wire 3 is crimped between the nut and the end face of the first crimping terminal 1 where the conductive blind hole 6 is formed. When the conductive plug-in member 8 is threadedly connected in the conductive blind hole 6, the external lead wire 3 is squeezed between the nut and the end face of the conductive blind hole 6. The nut structure increases the squeezing surface for the external lead wire 3, improving the firmness of the connection to the external lead wire 3.

[0037] As a preferred embodiment of the present utility model, the cable wiring device for electrical equipment further includes a second crimping terminal 4 extending in the same direction as the external lead wire 3. It is made of copper material. One end of the second crimping terminal 4 is crimped to the end of the external lead wire 3, and the other end is inserted between the nut and the end face of the first crimping terminal 1 where the conductive blind hole 6 is formed. Then during the connection process, only need to crimp the second crimping terminal 4 to the external lead wire 3 in advance, preferably by cold pressing or resistance welding, etc. The end of the second crimping terminal 4 that is not connected to the external lead wire 3 can be directly inserted between the nut and the end face of the conductive blind hole 6, improving the convenience during installation. Preferably, the end of the second crimping terminal 4 that is not connected to the external lead wire 3 is in the shape of an annular sheet structure, whose inner diameter is larger than the screw part of the conductive plug-in member 8 and smaller than the nut part of the conductive plug-in member 8, and then it is sleeved on the screw part of the conductive plug-in member 8, and then the nut part of the conductive plug-in member 8 is squeezed against the end face of the conductive blind hole 6; or preferably, the end of the second crimping terminal 4 that is not connected to the external lead wire 3 is in the shape of a fork structure and is inserted on the screw part of the conductive plug-in member 8, and then the nut part of the conductive plug-in member 8 is squeezed against the end face of the conductive blind hole 6.

[0038] Furthermore, a portion of the first crimping terminal 1 located between the conductive blind hole 6 and the conductive voltage tube 5 is provided with a limiting portion 7, and the electrical equipment is provided with a limiting seat that is snap-fitted with the limiting portion 7. The limiting portion 7 is limited by the limiting seat to ensure that when the conductive plug-in connector 8 is selected into the conductive blind hole 6, the entire first crimping terminal 1 will not rotate with the rotation of the conductive plug-in connector 8, thereby avoiding affecting the connection between the conductive voltage tube 5 and the winding lead-out wire 2.

[0039] Preferably, the radial cross section of the limiting portion 7 is a polygonal structure and surrounds the outer peripheral side of the first crimping terminal 1. A limiting channel for inserting the first crimping terminal 1 is provided on the limiting seat. The radial cross section of the limiting portion 7 matches the radial cross section of the limiting channel. It should be noted that the limiting channel extends in the same direction as the winding lead wire 2. After the winding lead wire 2 is connected to the first crimping terminal 1, the first crimping terminal 1 with the winding lead wire 2 is inserted into the limiting channel from one end, and the conductive blind hole 6 exposes the other end of the limiting channel and is then connected to the external lead wire 3 to complete the limiting work of the first crimping terminal 1, facilitate the fixing of the first crimping terminal 1 during installation, and reduce the reliability risk caused by improper installation. Furthermore, the limiting portion 7 is limited by the limiting channel provided on the mounting seat, and no additional parts are required, making the installation work simpler.

[0040] An electrical device is also provided, including an electrical device body, preferably the electrical device body includes a motor, a generator, etc., a junction box 9 is provided on the electrical device body, and through holes are opened on the junction box 9 for the winding lead wires 2 and the external lead wires 3 to extend into respectively, and a cable wiring device for the electrical device for connecting the winding lead wires 2 and the external lead wires 3 is provided in the junction box 9.
