[0033] The following describes the implementation of the present invention through specific examples, and those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific implementations, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that the following embodiments and features in the embodiments can be combined with each other without conflict.
[0034] It should be noted that the illustrations provided in the following embodiments are only used to schematically illustrate the basic concept of the present invention, and thus the illustrations only show components related to the present invention rather than being drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component may be changed arbitrarily, and the component layout may also be more complicated.
[0035] Example 1
[0036] like Figure 1-Figure 5As shown, the utility model provides a connection structure 100, which includes a base body 10, a sliding unit 11, a locking unit 12 and a plurality of conductors 13. The base body 10 is formed with a receiving groove 101. The sliding unit 11 is arranged in the receiving groove 101, and can slide along the extension direction of the receiving groove 101. The locking unit 12 is detachably connected to the sliding unit 11. A plurality of conductors 13 are stacked and each is formed with a waist-shaped hole 131. Among them, the sliding unit 11 is sequentially penetrated through the plurality of waist-shaped holes 131 and the receiving groove 101; one of the conductors 13 is fixedly connected to the base body 10, and another conductor 13 away from the base body 10 abuts against the locking unit 12, so as to fix the plurality of conductors 13 in connection.
[0037] It is worth noting that, through the arrangement of the seat body 10, the sliding unit 11 and the locking unit 12, and the cooperation between the sliding unit 11 and the waist-shaped hole 131 or the locking unit 12 and the waist-shaped hole 131, the connecting structure 100 allows for larger deviations when assembling the multiple conductors 13 to compensate for errors and deformations.
[0038] It is also worth noting that the locking unit 12 is detachably connected to the sliding unit 11, which can facilitate the assembly between the locking unit 12 and the sliding unit 11. The sliding unit 11 and the locking unit 12 in this embodiment can be connected by threads. After the two are threadedly connected, they have high strength and reliability, can withstand large loads and vibrations, and are not easy to loosen or break. At the same time, the threaded sliding unit 11 and the locking unit 12 are easy to disassemble and assemble, which is convenient for maintenance and replacement of parts. In addition, the threaded connection can be disassembled and assembled many times, avoiding the waste and cost increase caused by one-time fixation. Depending on the specific implementation environment, the locking unit 12 and the sliding unit 11 can also be connected by other detachable connection methods such as snap-on, sleeve connection, etc., to achieve the effect of facilitating assembly. This embodiment does not constitute a limitation on the connection method between the sliding unit 11 and the locking unit 12, but is only an example of its connection method.
[0039] In this embodiment, the locking unit 12 includes a first nut, and the sliding unit 11 includes a first bolt that cooperates with the first nut; the first bolt is sequentially passed through the plurality of waist-shaped holes 131 and the accommodating groove 101 .
[0040] In this embodiment, the receiving groove 101 includes a large diameter end 1011 and a small diameter end 1012 that are connected to each other. The sliding unit 11 is slidably disposed in the large diameter end 1011 , and the small diameter end 1012 has a limiting surface for limiting the rotation of the sliding unit 11 .
[0041] It is worth noting that the receiving groove 101 in this embodiment is a countersunk groove. The small diameter end 1012 of the receiving groove 101 can prevent the rotation of the sliding unit 11, thereby avoiding the occurrence of over-tightening. At the same time, the existence of the small diameter end 1012 of the receiving groove 101 can provide a visual indication, allowing the operator to see whether the sliding unit 11 has reached the limit position. This can facilitate the operator to ensure the quality and safety of the connection.
[0042] In this embodiment, the seat 10 is an insulating seat. It is understandable that the insulating seat can provide insulation protection, effectively isolate the electrical device from external contact, and prevent the current from passing through the human body or other conductive structures to cause electric shock hazards.
[0043] In this embodiment, the number of the conductors 13 is two; the long axis directions of the two waist-shaped holes 131 formed by the two conductors 13 are not parallel to each other.
[0044] It is worth noting that the long axis directions of the two waist-shaped holes 131 can be perpendicular to each other or form a small acute angle to allow a certain deviation between the conductors 13. Depending on the specific implementation environment, the number of conductors 13 can also be three, four, etc., and this embodiment does not constitute a limitation on the number of conductors 13.
[0045] Please refer again Figure 4 and Figure 5 , the multiple waist-shaped holes 131 formed by the multiple conductors 13 are not completely the same.
[0046] In this embodiment, at least one waist-shaped hole 131 formed by the conductor 13 has an opening 132 on one side to facilitate assembly.
[0047] The connection structure 100 provided in this embodiment may include the following assembly steps:
[0048] 1) Place the first bolt into the receiving groove 101 of the insulating seat;
[0049] 2) inserting the waist-shaped hole of one of the conductors 13 into the first bolt along the axial direction of the first bolt, and fixing the conductor 13 and the insulating seat together through mechanical structure, secondary injection molding, riveting and other processes;
[0050] 3) Slide the first bolt along the extension direction of the receiving groove 101 to align the first bolt with the front end opening 132 of another conductor 13;
[0051] 4) The waist-shaped hole with the opening 132 on the other conductor 13 is inserted into the first bolt from the direction of the opening 132 and from the front end opening 132; or the first bolt is inserted into the first bolt along the axial direction of the first bolt;
[0052] 5) Tighten the first nut on the first bolt to complete the connection.

The locking unit 12 is detachably connected to the sliding unit 11. A plurality of conductors 13 are stacked and each is formed with a waist-shaped hole 131. Among them, the locking unit 12 is sequentially penetrated through the plurality of waist-shaped holes 131 and the receiving groove 101; one of the conductors 13 is fixedly connected to the base body 10, and another conductor 13 away from the base body 10 abuts against the locking unit 12, so as to fix the plurality of conductors 13 in connection.

[0056] In this embodiment, the locking unit 12 includes a second bolt, and the sliding unit 11 includes a second nut that cooperates with the second bolt; the second bolt is sequentially passed through the plurality of waist-shaped holes 131 and the accommodating groove 101.
[0057] It is worth noting that in the connection structure 100 of this embodiment, the first bolt buried in the insulating base is replaced by a second nut. The second bolt is driven in from the outside during assembly, which can further reduce the structural size space.
[0058] The connection structure 100 provided in this embodiment may include the following assembly steps:
[0059] 1) Place the second nut into the receiving groove 101 of the insulating seat;
[0060] 2) Fix one of the conductors 13 to the insulating seat body through mechanical structure, secondary injection molding, riveting and other processes, and at this time, the waist-shaped hole 131 of the conductor 13 is aligned with the screw hole of the nut;
[0061] 3) Assemble another conductor 13 on the upper surface of the conductor 13 in step 2), and slide the second nut so that the second nut is aligned with the waist-shaped holes 131 of the two conductors 13;
