[0034] As shown in Figures 1 to 3 The contactor comprises a base body 100, an upper base 200 and a flexible electrical connecting piece 300, the inside of the base body 100 is provided with a relay conductive piece 110; the upper base 200 is fixed above the base body 100, the upper base 200 is provided with a wiring terminal 210, and the upper base 200 is provided with a lead slot 220 connecting the inside of the base body 100 and the wiring terminal 210; one end of the flexible electrical connecting piece 300 is connected to the wiring terminal 210, the other end is connected to one end of the relay conductive piece 110, at least part of the flexible electrical connecting piece 300 is clamped in the lead slot 220; the working coil 410 is arranged below the outside of the base body 100, the other end of the relay conductive piece 110 is in conductive connection with the working coil 410.

[0035] In this embodiment, the contactor is assembled from an upper base 200 and a base body 100. The upper base 200 and the base body 100 are separately arranged, allowing the upper base 200 to change its shape and size according to the installation environment, thus adapting to different installation spaces. The upper base 200 is provided with a terminal block 210, and the base body 100 contains a conductive adapter 110. The working coil 410 is installed on the outside below the base body 100. The terminal block 210 and the conductive adapter 110 are connected by a flexible electrical connector 300, thereby enabling the flexible... The flexible electrical connector 300 can be bent and adjusted according to the installation environment, making it suitable for various complex installation spaces. Wiring is more convenient and installation is more stable. Simultaneously, the flexible electrical connector 300 is snapped into the lead groove 220 of the upper base 200, ensuring a more secure fixation. This prevents damage from external objects and fatigue fracture caused by repeated bending, further improving installation stability and ensuring the wiring is not easily detached, thus guaranteeing stable operation of the contactor's working coil 410. This contactor enables more stable operation of the contactor's working coil 410 and facilitates wiring of the working coil 410, making it suitable for various confined installation environments.

[0036] The flexible electrical connector 300 described herein is an electrical wire or a flexible ribbon cable. The electrical wire consists of one or more flexible conductors covered with a soft sheath, or bare conductors can be used directly as the flexible electrical connector 300. The flexible ribbon cable consists of two layers of insulating foil with a flat conductor sandwiched between them. The conductor is preferably copper. As an optional embodiment, it can be replaced with aluminum or silver, metals with good conductivity and ductility, or other non-metals with high conductivity and flexibility, such as glass fiber composite conductors or carbon fiber composite conductors, which will not be elaborated further here.

[0037] It should be noted that the base body 100 is mounted on the base 400, and the working coil 410 of the contactor is installed inside the base 400. Figure 7 As shown in the figure, the working coil 410 is electrically connected to an external power source (not shown) in sequence through a connecting conductive element 110, a flexible electrical connector 300, and a terminal block 210. The terminal block 210 includes two parts, A1 and A2. Each terminal block 210 is connected to a connecting conductive element 110 through a flexible electrical connector 300, thereby realizing the circuit connection between the working coil 410 and the power source. When the circuit is connected, the contactor is closed.

[0038] Furthermore, a dust cover 500 is also provided on the base body 100. The dust cover 500 covers the upper base 200 to realize the dustproof function of the contactor, prevent dust and debris from falling into the contactor, and thus ensure that the contactor can work normally in complex environments.

[0039] As shown in Figure 3 and Figure 4 Optionally, the wiring terminal 210 and the adapter conductive member 110 are arranged staggered in the first direction and spaced apart in the second direction, the wiring terminal 210 is arranged higher than the adapter conductive member 110 in the vertical direction, the lead slot 220 comprises a first slot 221, a second slot 222 and a third slot 223 connected in series, the first slot 221 is arranged extending in the vertical direction, the top of the first slot 221 extends to the wiring terminal 210, the second slot 222 is arranged extending in the first direction, the third slot 223 is arranged extending in the second direction, the third slot 223 extends to the base body 100 and communicates with the inside of the base body 100, the first direction is not parallel to the second direction, and both the first direction and the second direction are perpendicular to the vertical direction. Since the positions between the wiring terminal 210 and the adapter conductive member 110 are not always in the same plane or in the same direction, the flexible electrical connection member 300 needs to be bent to realize the electrical connection between the adapter conductive member 110 and the wiring terminal 210. In order to ensure that the bent flexible electrical connection member 300 is firmly clamped by the lead slot, the lead slot 220 can be arranged in the state that the first slot 221, the second slot 222 and the third slot 223 are connected in series, and the three are arranged extending in the vertical direction, the first direction and the second direction respectively, realizing the fixation of the flexible electrical connection member 300 in different bending angles by the lead slot. Specifically, the first direction and the second direction are perpendicular to each other and perpendicular to the vertical direction, so that the clamping fixation of the bent flexible electrical connection member 300 can be realized.

[0040] It should be noted that after the flexible electrical connection member 300 is drawn out from the wiring terminal 210, it is first drawn downward in the vertical direction, then bent and drawn out in the first direction, then bent and drawn out in the second direction, then bent again and drawn out in the vertical direction into the connecting hole 120, and finally drawn out in the second direction and connected to the adapter conductive member 110, realizing the electrical connection between the wiring terminal 210 and the adapter conductive member 110. The flexible electrical connection member 300 is in the lead slot or the connecting hole 120 after being bent, and the fixation effect is better. The flexible electrical connection member 300 will not be detached or broken due to external impact, and the electrical connection between the wiring terminal 210 and the adapter conductive member 110 is more stable.

[0041] Further, the top of the second slot 222 and / or the top of the third slot 223 is provided with a clamping protrusion 224, and the flexible electrical connecting piece 300 is clamped between the clamping protrusion 224 and the inner bottom wall of the second slot 222. The clamping protrusion 224 can fix the flexible electrical connecting piece 300 on the inner bottom wall of the lead slot 220. The flexible electrical connecting piece 300 is tightly fixed on the inner bottom wall of the second slot 222 or the third slot 223 by the clamping protrusion 224, which can improve the stability of the clamping and fixing of the flexible electrical connecting piece 300 in the lead slot 220, and can also protect the flexible electrical connecting piece 300, thereby improving the stability of the electrical connection of the working coil 410 of the contactor.

[0042] In the embodiment, the second slot 222 is provided with the clamping protrusion 224, because the length of the second slot 222 is greater, and the installation space is larger, which will not be described here.

[0043] Please continue to refer to Figure 3 and Figure 4 Optionally, the top of the connection between the second slot 222 and the third slot 223 is also provided with the clamping protrusion 224. Because the connection between the second slot 222 and the third slot 223 is the bending position of the flexible electrical connecting piece 300, the flexible electrical connecting piece 300 is prone to warping at this position. The clamping protrusion 224 is arranged at the connection between the second slot 222 and the third slot 223, which can prevent the corner of the bending position from warping, and can wrap and fix the bending position, thereby ensuring the connection stability of the flexible electrical connecting piece 300.

[0044] In the embodiment, the clamping protrusion 224 at the connection is provided with a chamfer, so as to avoid covering the corner of the connection between the second slot 222 and the third slot 223, and to ensure that the flexible electrical connecting piece 300 can be easily clamped into the lead slot 220, thereby improving the convenience of installation.

[0045] Further, any one of the two slot side walls of the second slot 222 at the two ends in the second direction is provided with a clamping protrusion 225, which protrudes towards the other slot side wall. The clamping protrusion 225 is used to make the flexible electrical connecting piece 300 abut against the other slot side wall. It should be noted that the inner side wall of the clamping protrusion 225 can form part of the slot side wall of the second slot 222 in the embodiment. The clamping protrusion 225 is in the form of an arc or arch, or is directly provided in the form of a column, as long as the size of the second slot 222 in the second direction is reduced. In this way, the flexible electrical connecting piece 300 can be clamped and fixed between the clamping protrusion 224 and the other slot side wall.

[0046] It should be noted that if the size of the second groove 222 in the first direction is too large, the clamping protrusions 225 can be provided with two, and the clamping protrusions 224 are arranged between the two clamping protrusions 225, so that the flexible electrical connector 300 can be clamped and fixed by the clamping protrusions 224, the two clamping protrusions 225 and the second groove 222, and the fixing effect is better.

[0047] Optionally, the inner bottom wall of the third groove 223 is in communication with the inside of the base body 100. Specifically, the inner bottom wall of the third groove 223 is provided with a communication hole 2231 for communicating the third groove 223 and the second part 122 of the connecting hole 120, and the communication hole 2231 penetrates the end wall of the upper base 200 along the second direction, so that not only the clamping of the flexible electrical connector 300 in the third groove 223 can be achieved, but also a certain elastic space for the bending of the flexible electrical connector 300 can be provided, avoiding the friction between the flexible electrical connector 300 and the third groove 223 after bending, avoiding the flexible electrical connector 300 from falling off, and further improving the installation stability of the flexible electrical connector 300.

[0048] As shown in Figures 3 to 5 The base body 100 is provided with a connecting hole 120 extending in the vertical direction, the adapter conductive part 110 is arranged in the connecting hole 120, one end of the lead slot 220 extends to the connecting hole 120 and is in communication with the connecting hole 120, and at least part of the flexible electrical connector 300 is arranged in the connecting hole 120. The arrangement of the connecting hole 120 not only can accommodate the adapter conductive part 110, but also can accommodate part of the flexible electrical connector 300, and in cooperation with the lead slot 220, the clamping and accommodation of the flexible electrical connector 300 can be achieved, the flexible electrical connector 300 is further protected, avoiding the collision of the flexible electrical connector 300 by external objects during installation in a small space, ensuring the firm connection of the two ends of the flexible electrical connector 300 with the terminal 210 and the adapter conductive part 110, and improving the stability of the electrical connection.

[0049] Specifically, the top wall of the base body 100 protrudes an installation boss 130, and the installation boss 130 is provided with the connecting hole 120; the connecting hole 120 includes a first part 121 and a second part 122 that are in communication with each other, the inner bottom wall of the lead slot 220 is in communication with the first part 121, the adapter conductive part 110 is threaded through the second part 122, the first part 121 is arranged to extend in the second direction, the second part 122 is arranged to extend in the vertical direction, and the dimension of the second part 122 in the first direction is not less than the dimension of the first part 121 in the first direction. The installation boss 130 in the embodiment can make the top port of the connecting hole 120 higher than the top wall of the base body 100, and after the adapter conductive part 110 is threaded through the connecting hole 120, the top of the adapter conductive part 110 is still at a certain distance from the top port of the connecting hole 120, thereby being used to accommodate a part of the flexible electrical connecting part 300; at the same time, the connecting hole 120 includes the first part 121 and the second part 122 that are in communication with each other, the first part 121 is used to accommodate the flexible electrical connecting part 300 that extends in the second direction after being bent, and the second part 122 is used to thread through the adapter conductive part 110 and the flexible electrical connecting part 300 that extends in the vertical direction after being bent, thereby completely accommodating the flexible electrical connecting part 300, and the protection effect on the flexible electrical connecting part 300 is better.

[0050] Optionally, as shown in Figure 6 the adapter conductive part 110 is provided with an anti-falling flange 111 at the top, and the flexible electrical connecting part 300 is wound around the adapter conductive part 110 and abuts against the bottom of the anti-falling flange 111. The arrangement of the anti-falling flange 111 can prevent the flexible electrical connecting part 300 from falling off the top of the adapter conductive part 110, further improve the connection stability of the flexible electrical connecting part 300 and the adapter conductive part 110, ensure the wiring stability of the working coil 410, and improve the working stability of the contactor.

[0051] It should be noted that the adapter conductive part 110 is a long bolt, the long bolt is threadedly fixed to the base 400, and the anti-falling flange 111 is the head of the long bolt, which will not be described here again.

[0052] In the embodiment, the top wall of the anti-falling flange 111 is not higher than the top port of the connecting hole 120.
