[0037] Embodiment 1
[0038] This embodiment provides a wiring structure of a contactor, as shown in the attached Figures 1-4 figure, including:
[0039] The main body 11 is provided with a receiving cavity 111 and a wiring cavity 112. A coil 12 and other components are fixed in the receiving cavity 111. The structure in the receiving cavity 111 is the prior art, so it will not be described in detail in this embodiment. The wiring cavity 112 specifically refers to the wiring structure formed in cooperation with the wiring member 13 to achieve the effect of controlling the operation of the coil 12, rather than the wiring structure of the input end and the output end. The wiring cavity 112 communicates with the receiving cavity 111, and the wiring cavity 112 is provided with a limiting groove 113. In addition, it should be noted that the wiring cavity 112 is provided with a wiring hole 1121 and a wire passing hole 1122. The wiring hole 1121 is for a tool to pass through the wiring hole 1121 to drive the bolt assembly 14 to rotate, and the wire passing hole 1122 is for an external wire to extend into the wiring cavity 112 to be connected to the wiring member 13 to form an electrical connection effect. Here, the central axis of the wiring hole 1121 is perpendicular to the central axis of the wire passing hole 1122.
[0040] The wiring member 13 is accommodated in the wiring cavity 112, and the wiring member 13 extends into the receiving cavity 111. The part of the wiring member 13 extending into the receiving cavity 111 forms an electrical connection effect with the enameled wire of the coil 12. The wiring member 13 is provided with a fixing portion 131 and a limiting portion 132. The limiting portion 132 cooperates with the limiting groove 113, the fixing portion 131 is connected to the limiting portion 132, and the fixing portion 131 is provided with a first through hole 133.
[0041] The bolt assembly 14 is accommodated in the wiring cavity 112, and the bolt assembly 14 cooperates with the first through hole 133. Through the cooperation of the limiting portion 132 and the limiting groove 113, the connection and fixing effect between the wiring member 13 and the wiring cavity 112 is increased, preventing the wiring member 13 from rotating due to violent wiring during the process of screwing the screw 141. This structure improves the fixing strength of the wiring member 13, so that it will not rotate even during violent wiring, improving the stability and reliability of the wiring.
[0042] Specifically, the fixing portion 131 is vertically connected to the limiting portion 132. The vertically connected setting forms a locking effect in the horizontal direction, further improving the anti-rotation effect of the wiring member 13. Here, the fixing portion 131 is located on the horizontal plane, the limiting portion 132 is vertically upward, or the limiting portion 132 is vertically downward, forming a fitting and fixing effect with the corresponding limiting groove 113. In addition, the limiting portion 132 can also extend horizontally outward to form a fit with the limiting groove 113.
[0043] Specifically, as shown in the appendix Figures 3-4As shown, the limiting part 132 is perpendicularly connected to the side wall of the fixing part 131. Or, the limiting part 132 is perpendicularly connected to the bottom surface of the fixing part 131. In this embodiment, taking the case where the limiting part 132 is perpendicularly connected to the side wall of the fixing part 131, the number of the limiting parts 132 here is two, and the two limiting parts 132 are symmetrically arranged. It should be noted that the limiting part 132 is not located on the side close to the wire passing hole 1122. The two limiting parts 132 extend vertically downward to form an inverted U-shaped structure, and the corresponding number of limiting grooves 113 is two. Further, in this embodiment, the wiring member 13 is integrally bent and formed, that is, the limiting part 132 is bent and formed. When the limiting part 132 is perpendicularly connected to the bottom surface of the fixing part 131, it can be a plug-in connection here, or a welding, etc.
[0044] Specifically, as shown in the appendix Figures 3-4 As shown, the fixing part 131 is provided with a stud 134, and the stud 134 is provided with a threaded hole 1341. The threaded hole 1341 and the first through hole 133 are coaxially arranged, and the bolt assembly 14 is matched with the first through hole 133 and the threaded hole 1341. The setting of the threaded hole 1341 increases the contact area with the bolt assembly 14 to ensure that the screw 141 will not slip during the screwing process. Here, the stud 134 extends downward.
[0045] Specifically, the bolt assembly 14 includes a screw 141 and a washer 142. The washer 142 is located above the fixing part 131. The screw 141 passes through the washer 142, the first through hole 133, the threaded hole 1341 and is fixedly connected to the wiring cavity 112. Here, the screw 141 and the threaded hole 1341 are in interference fit. The interference fit further improves the connection strength between the screw 141 and the threaded hole 1341 to ensure the fixing stability of the wiring member 13.
[0046] Specifically, the limiting groove 113 is provided with a guiding surface 1131. The setting of the guiding surface 1131 forms a guiding effect. Here, the guiding surface 1131 can be an inclined surface or a curved surface.
[0047] Specifically, as shown in the appendix Figures 3-4As shown in the figure, the wiring cavity 112 is provided with a fixing post 114. In this embodiment, the number of the limiting grooves 113 is two, and the two limiting grooves 113 are respectively arranged on both sides of the fixing post 114. The fixing post 114 is provided with a fixing hole 1141, and the fixing hole 1141 and the first through hole 133 are coaxially arranged. The bolt assembly 14 passes through the first through hole 133 and is connected to the fixing hole 1141. The setting of the fixing hole 1141 further improves the fixing effect of the bolt assembly 14. In this embodiment, the screw 141 passes through the first through hole 133, the threaded hole 1341 and is connected and fixed to the fixing hole 1141. Further, in this embodiment, the screw 141 and the fixing hole 1141 are also in interference fit. In addition, it should be noted that when the wiring member 13 is fixedly combined with the bolt assembly 14, the two limiting portions 132 are respectively combined with the two limiting grooves 113 to form clamping on both sides and are fastened by the screw 141 in the middle. At this time, the limiting portions 132 will also form a clamping and fixing effect, further improving the fixing strength of the wiring member 13.
[0048] Specifically, as shown in the attached Figures 1-3 figure, the body 11 includes a base 15 and a base 16. The base 15 and the base 16 cooperate to form a wiring cavity 112 and a receiving cavity 111. Here, the connection and fixing method between the base 15 and the base 16 can be bolt connection or snap connection. In this embodiment, the limiting groove 113 and the fixing post 114 are both arranged on the base 16. The base 15 and the base 16 cooperate to form a plurality of overlapping regions, and the overlapping regions are respectively arranged on both sides of the wiring cavity 112. The number of the overlapping regions here is adjusted according to actual needs. In this embodiment, the number of the wiring cavities 112 is two, and at this time, the number of the overlapping regions can be three or four, increasing the strength of the side walls of the wiring cavity 112. The setting of the overlapping regions increases the strength on both sides of the wiring cavity 112; if a single base 15 or base 16 is designed too thick, local shrinkage is likely to occur, resulting in insufficient strength; at the same time, the overlapping regions also play a role in limiting the washer 142, preventing the washer 142 from being horizontal. In this embodiment, the overlapping regions specifically refer to the overlap in the vertical height direction.
[0049] Specifically, as shown in the attached Figures 1-3 figure, one of the base 15 and the base 16 is provided with a protrusion 17, and the other of the base 15 and the base 16 is provided with a groove 18 that cooperates with the protrusion 17. The protrusion 17 and the groove 18 cooperate to form an overlapping region; or, one of the base 15 and the base 16 is provided with a stepped groove 19, and the other of the base 15 and the base 16 is provided with a stepped boss 20 that cooperates with the stepped groove 19. The stepped groove 19 and the stepped boss 20 cooperate to form an overlapping region. In this embodiment, taking four overlapping regions as an example, the two overlapping regions in the middle are formed by the cooperation of the protrusion 17 and the groove 18, and the two overlapping regions on both sides are formed by the cooperation of the stepped groove 19 and the stepped boss 20. Those skilled in the art can also adjust the corresponding structure according to actual needs.
[0050] Specifically, as shown in the appendix Figures 1-3 shown, it further includes a flexible connector 21. One end of the flexible connector 21 is connected to the coil 12, and the other end of the flexible connector 21 is connected to the wiring member 13. The setting of the flexible connector 21 forms a buffer area, further improving the connection effect between the wiring member 13 and the coil 12. Even if the wiring member 13 twists, it will not cause the wiring piece to move together with the enameled wire like the old product, and finally lead to the problem of failure caused by the breakage of the enameled wire of the coil 12. Here, the flexible connector 21 can be a wire or a soft copper wire.
[0051] Specifically, the wiring cavity 112 is provided with a reduced-diameter portion 115. The wiring hole 1121 is provided in the reduced-diameter portion 115 to prevent the entire bolt assembly 14 from sliding out of the wiring cavity 112.
[0052] Obviously, the above embodiments are merely examples given for clear illustration and are not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or variations can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. And the obvious changes or variations derived therefrom are still within the protection scope of the present invention.
