Furthermore, the terms "first," "second," "third," and the like are used solely to distinguish one from another and are not to be construed as indicating or implying relative importance.

In the description of the present application, it is further noted that, unless expressly stated or limited otherwise, the terms "disposed," "mounted," "connected," and "connected" are to be construed broadly, e.g., as meaning either a fixed connection, a removable connection, or an integral connection; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present application can be understood in a specific case by those of ordinary skill in the art.

In one aspect of the embodiment of the present application, a switch body is provided, as shown in fig. 1 to 3, including the switch module 120, and the contact assembly and the wiring tube 130 that are disposed on the switch module 120, so that when the switch body is wired, the wiring tube 130 can be used for wiring in a plug-in manner, which can avoid disposing parts such as a screw 140 inside the switch body, and reduce the space occupied by the wiring part. Specifically, the method comprises the following steps:

as shown in fig. 1, a contact assembly (not shown in fig. 1) is disposed on the switch module 120, and the contact assembly has a closing state and an opening state, and correspondingly, when the contact assembly is in the closing state, it indicates that the circuit where the switch module 120 is located is on, and when the contact assembly is in the opening state, it indicates that the circuit where the switch module 120 is located is off, the contact assembly can be switched between the closing state and the opening state by driving the contact assembly to move.

As shown in fig. 1 and 2, the connection tube 130 is also disposed in the switch module 120, and the connection tube 130 is electrically connected to the contact assembly, so that when the switch body needs to be connected, the end of the wire 150 can be inserted into the connection tube 130, so that the wire 150 contacts with the inner wall of the connection tube 130 to form an electrical connection relationship between the wire 150 and the connection tube 130, and the contact assembly (i.e., the switch module 120 or the switch body) electrically connected to the connection tube 130 is connected to a loop, so that on/off control of the loop connected to the switch body can be realized by switching a closing state and an opening state of the contact assembly. When the disconnection is required, the end of the wire 150 may be pulled out from the inside of the connection tube body 130, so that the wire 150 is separated from the connection tube body 130, and the electrical connection between the wire 150 and the connection tube body 130 is released.

Therefore, when the switch body adopts the wiring tube body 130 for wiring: on one hand, the structural form of the wiring tube body 130 can be utilized, so that the end part of the lead 150 can be directly inserted into the wiring tube body 130 or can be pulled out from the wiring tube body 130 to complete the wiring of the switch body, thereby simplifying the complex operation during the wiring of the switch body; on the other hand, based on the structural configuration of the connecting tube body 130, when the end of the wire 150 is directly inserted into the connecting tube body 130, the connecting tube body 130 can cover the outer circumferential wall of the wire 150, so that the two form a reliable electrical connection; on the other hand, the wire 150 is directly inserted into and pulled out of the wiring tube 130, so that fewer parts are needed for wiring of the switch body, the parts such as the screw 140 are not needed, the occupied space is small, the layout difficulty of all the parts in the switch body can be reduced, and the miniaturization of the switch body is facilitated.

In some embodiments, in order to further improve the contact stability between the wire 150 and the terminal tube body 130, the wire 150 may be in an interference fit with the terminal tube body 130 after being inserted into the terminal tube body.

In some embodiments, as shown in fig. 3, the wire 150 may include a wire body 153, a plug 151 and a sheath 152, wherein the plug 151 is used as an electrical conductor at an end of the wire body 153, the sheath 152 is used as an insulator and is disposed at an outer periphery of the two, an end of the plug 151 has an exposed portion opposite to the sheath 152, and when the wire 150 is inserted into the connection tube body 130, as shown in fig. 7 to 9, the exposed portion at the end of the plug 151 may be inserted into the connection tube body 130. In some embodiments, the sheath 152 may be provided with a non-slip groove at the periphery thereof to facilitate stable access by a user, and in addition, a ring protrusion may be provided at the periphery of the sheath 152 to cooperate with the stopper 182 in the following embodiments.

In some embodiments, as shown in fig. 1 and 2, the contact assembly and the terminal body 130 are located in the switch module 120, so that the contact assembly and the terminal body 130 can be effectively protected and electrically isolated by the switch module 120.

In some embodiments, as shown in fig. 1, 2 and 3, the connection tube 130 is hollow, and the connection cavity 131 is formed by the hollow area, and a connection port 132 communicating with the connection cavity 131 is formed at one end of the connection tube 130 to facilitate insertion of the plug 151 of the wire 150.

In some embodiments, as shown in fig. 1 and fig. 2, when the wiring tube body 130 is located in the switch module 120, the switch module 120 may be provided with an opening 122 corresponding to the position of the wiring port 132 of the wiring tube body 130, so that when the wire 150 needs to be inserted, the end of the wire 150 can be inserted into the wiring cavity 131 of the wiring tube body 130 through the opening 122 and the wiring port 132, thereby achieving fast wiring of the switch body. In some embodiments, the opposite ends of the connection tube body 130 may be provided with the connection ports 132, which is not limited in this application.

In some embodiments, as shown in fig. 3, a slit 134 may be axially formed in a side wall of the connection tube 130, the slit 134 may be a slit 134 existing between an end and an end when an original material forming the connection tube 130 is bent to form a tube structure, or a slit 134 may be formed in the integrally formed connection tube 130, and by using the slit 134, when the end of the wire 150 is inserted, the connection tube 130 is easily deformed to match the end of the wire 150, so that the wire 150 and the connection tube 130 are in close contact with each other.

In some embodiments, the radial cross-sectional shape of the connecting tube body 130 may be a triangle, a quadrangle, a pentagon, a circle (shown in fig. 3), an ellipse, any ring shape, and the like, which is not limited herein as long as it can form an electrical connection relationship with the end of the inserted wire 150. In order to further improve the contact reliability of the conductive wire 150 with the terminal body 130, the end shape of the conductive wire 150 may be matched to the shape of the terminal body 130.

In some embodiments, as shown in fig. 1 and 2, it is understood that more than two wiring tube bodies 130 may be disposed on the switch module 120, and therefore, each wiring tube body 130 may have a gap 123 with a certain width with the opening 122 of the switch module 120, so that a creepage distance between two adjacent wiring tube bodies 130 can be effectively increased compared to when the wiring tube bodies 130 are in direct contact with the inner wall of the opening 122, thereby improving reliability and stability of the switch body.

In some embodiments, as shown in fig. 3, the contact assembly includes a movable contact (not shown in fig. 3) and a fixed contact 160 that are engaged with each other, and when actually engaged, the movable contact may be movably disposed (e.g., rotate or slide) on the switch module 120, and when driven, the movable contact may be in contact with the fixed contact 160 (the contact assembly is in a closed state) or separated from the fixed contact 160 (the contact assembly is in an open state). As shown in fig. 3, when the contact assembly is electrically connected to the wiring tube 130, the fixed contact 160 may be connected to the wiring tube 130, that is, one end of the fixed contact 160 may be used as a mating end with the movable contact, and the other end of the fixed contact 160 may be connected to the wiring tube 130, for example, the movable contact and the wiring tube 130 are respectively located at two opposite sides of the fixed contact 160. It should be understood that the stationary contact 160 and the connecting tube 130 may be integrally formed, or may be separately formed and then connected by welding or the like.

In some embodiments, as shown in fig. 3, the connection pipe body 130 has a pipe body central axis 133, and when the end of the static contact 160 is connected to the connection pipe body 130, the end of the static contact 160 may be deviated from the pipe body central axis 133, that is, as shown in fig. 3, the end of the static contact 160 connected to the connection pipe body 130 is located above the pipe body central axis 133, and of course, in other embodiments, the end of the static contact 160 connected to the connection pipe body 130 may also be located below the pipe body central axis 133, or the end of the static contact 160 connected to the connection pipe body 130 is coplanar with the pipe body central axis 133.

In some embodiments, the switch body may be a single-side wiring or a double-side wiring, as shown in fig. 1 and 2, for convenience of distinguishing, two opposite sides of the switch module 120 may be respectively used as a front side (as shown in fig. 1) and a back side (as shown in fig. 2), where the front side may be a window of the chassis 10 where the switch module 120 is installed, and when the switch body needs to be subjected to double-side wiring, the wiring pipe bodies 130 may include at least two wiring pipe bodies 130, where the at least two wiring pipe bodies 130 are divided into two groups, one group is distributed on the front side of the switch module 120, and the other group is distributed on the back side of the switch module 120, so that double-side wiring may be performed on the front side and the back side of the switch module 120.

In some embodiments, as shown in fig. 1, 2 and 4, the switch module 120 includes a plurality of switch units 121 arranged in a row, the plurality of switch units 121 may be arranged in a straight line in sequence, and a contact assembly and a connection pipe body 130 connected to each other are disposed in each switch unit 121, so that each switch unit 121 can access one loop through the connection pipe body 130 and control the on/off of the loop. It should be understood that the contact assembly provided in each switch unit 121 may be a group, but the number of the terminal body 130 corresponding to the contact assembly may be one, two or more, and when selected, may be determined according to a desired disconnection point in the switch unit 121.

For example, as shown in fig. 1 and fig. 2, the switch module 120 includes eight switch units 121, each switch unit 121 is provided with a set of contact assemblies and two connection pipe bodies 130 connected to the set of contact assemblies, that is, the entire switch module 120 has sixteen connection pipe bodies 130, as shown in fig. 1, the eight connection pipe bodies 130 are distributed on the front side of the switch module 120, the eight connection pipe bodies 130 are divided into two rows, each row is arranged along the length direction b of the switch module 120, and the connection pipe bodies 130 between the two rows are distributed in a staggered manner, so that the creepage distance can be increased; as shown in fig. 2, the other eight connection tube bodies 130 are distributed on the back of the switch module 120, the eight connection tube bodies 130 are also divided into two rows, each row is also arranged along the length direction b of the switch module 120, and the connection tube bodies 130 between the two rows are distributed in a staggered manner, so that the creepage distance can also be increased; as shown in fig. 1 and 2, the two connection tube bodies 130 connected to the same contact assembly may be respectively located on the front and the back of the switch module 120, so that the overall size of the switch module 120 can be effectively reduced while the creepage distance is increased by combining the staggered distribution of the connection tube bodies 130.

When there are two connection tube bodies 130 in the switch unit 121, the contact assembly of the switch unit 121 may be a double-breakpoint structure, for example, in a loop where the same switch unit 121 is located, the contact assembly includes a movable contact and two fixed contacts 160 matched with the movable contact. When the two fixed contacts 160 are respectively located on the front and the back of the switch module 120, the two wiring tube bodies 130 are also respectively located on the front and the back of the switch module 120, and each wiring tube body 130 is connected to one fixed contact 160.

In some embodiments, as shown in fig. 1 and 4, a first clamping portion 124 and a second clamping portion 125 are respectively disposed on two adjacent switch units 121, and the first clamping portion 124 and the second clamping portion 125 are matched with each other, after the two adjacent switch units 121 are connected, the first clamping portion 124 and the second clamping portion 125 on the two adjacent switch units 121 are also in a clamping limit state, and the limit direction of the first clamping portion 124 and the second clamping portion 125 is the same as the plugging direction of the wire 150, for example, in fig. 1, the two adjacent switch units 121 are limited in the direction a by the clamping limit of the first clamping portion 124 and the second clamping portion 125, so as to enhance the overall strength in the direction a, and when the plugging direction of the wire 150 is the same as the direction a, the overall structural strength of the switch module 120 can be increased by the clamping limit of the first clamping portion 124 and the second clamping portion 125, instability such as looseness of each switch unit 121 caused by plugging and unplugging the wires 150 is avoided.

For example, as shown in fig. 4, an insertion convex portion (a first clamping portion 124) extending toward the right switch unit 121 is disposed on the left switch unit 121, an insertion groove (a second clamping portion 125) for accommodating the insertion convex portion of the left switch unit 121 is disposed on the right switch unit 121, and after the left switch unit 121 and the right switch unit 121 are connected, the insertion convex portion is horizontally inserted into the insertion groove, so that the switch unit is integrally reinforced in the vertical direction a, and when the connection pipe 130 disposed on the switch unit 121 is vertically inserted into and pulled out of the wire 150, the overall structural strength of the switch module 120 can be effectively increased.

In some embodiments, as shown in fig. 5 and 6, the switch module 120 is disposed inside the chassis 10, and the switch module 120 may be connected and fixed to the inside of the chassis 10 by screws 140, or may be fixed by other fixing methods such as clamping. When the switch module 120 is fixed inside the casing 10, the switch module 120 should have one side of the connection tube 130, that is, the connection side of the switch module 120 corresponds to the window of the casing 10, so as to facilitate the insertion and extraction of the wires 150 through the window and the connection tube 130 on the switch module 120. It should be noted that, when the switch module 120 is a double-sided, three-sided or multi-sided wiring, one side thereof may correspond to the window of the chassis 10. It should also be understood that the wiring side of the switch module 120 corresponds to the window of the enclosure 10, and should include positive and partial positive correspondence.

As shown in fig. 7 and 8, when the wires 150 are plugged into the front surface of the switch module 120, the plugs 151, which may be ends of the wires 150, are partially inserted into the connecting tube bodies 130 in the switch module 120 (the switch unit 121) through the windows on the chassis 10.

As shown in fig. 7 and 9, when the wires 150 are inserted into the rear surface of the switch module 120, the plug 151, which may be an end of the wires 150, is partially inserted directly into the connecting tube body 130 in the switch module 120 (the switch unit 121).

In some embodiments, as shown in fig. 5 and 6, the switch body further includes a sealing assembly 170, and the sealing assembly 170 is installed at the window of the enclosure 10, so that the window on the enclosure 10 can be sealed by the sealing assembly 170, and then the inside of the enclosure 10 and the outside of the enclosure 10 are effectively isolated. It should be understood that the sealing assembly 170 may seal the window of the enclosure 10 from the outside of the enclosure 10 as shown in fig. 5 and 6, and may seal the window of the enclosure 10 from the inside of the enclosure 10 in other embodiments.

In some embodiments, as shown in fig. 5 to 15, the sealing assembly 170 includes an annular sealing seat 190 and a sealing cover 180 installed at a window of the chassis 10, the sealing cover 180 is detachably connected to the annular sealing seat 190, and meanwhile, in order to facilitate wiring of the switch module 120 inside the chassis 10, a mounting hole 183 may be further provided on the sealing cover 180, the mounting hole 183 is connected to the wiring tube body 130 on the wiring side of the switch module 120 through an inner ring of the annular sealing seat 190, so that an end of the wire 150 can pass through the mounting hole 183 and the inner ring of the annular sealing seat 190 to be plugged into the wiring tube body 130. It should be understood that the number and positions of the mounting holes 183 provided on the sealing cover 180 should each correspond one-to-one to the number and positions of the wiring tube bodies 130 on the wiring side of the switch modules 120 and the windows provided inside the cabinet 10, so that accurate wiring can be facilitated.

In some embodiments, as shown in fig. 7, 10 and 15, a limiting portion 182 may be disposed on the sealing cover 180, and the limiting portion 182 may be engaged and abutted with the lead 150 inserted into the mounting hole 183, so as to limit the lead 150 to the sealing cover 180, for example, as shown in fig. 3 and 15, after the end of the lead 150 is inserted into the mounting hole 183, the annular protrusion on the lead 150 may be abutted with the limiting portion 182 on the sealing cover 180, so as to limit the lead 150 to the sealing cover 180 without falling off, so that when the lead 150 is inserted into the switch module 120 inside the chassis 10, the lead 150 may be assembled with the mounting hole 183 and the limiting portion 182 of the sealing cover 180, and at this time, since the sealing cover 180 is not yet connected with the annular sealing seat 190, the lead 150 is easily assembled on the sealing cover 180 without being limited by the environment, and then the sealing cover 180 with the lead 150 may be integrally mounted on the annular sealing seat 190, the installation hole 183 and the limiting part 182 can be used for positioning and limiting the lead 150, so that the lead 150 and the wiring pipe body 130 of the switch module 120 are aligned and spliced, wiring of the switch module 120 can be completed, wiring difficulty caused by environmental limitation when the traditional direct wiring on the switch body is conducted can be effectively improved, and labor intensity of wiring of a user is reduced.

In addition, due to the limitation of the limiting part 182, after the wiring is completed, the limiting part 182 mainly bears the weight of the lead 150, that is, the sealing cover 180 bears the weight of the lead 150, so as to ensure the stability of the plug connection of the lead 150 and the switch module 120.

In some embodiments, as shown in fig. 10 and 15, the limiting portion 182 is a limiting protrusion located on the peripheral side of the mounting hole 183, and may be disposed annularly, and the limiting protrusion is disposed on one side of the sealing cover 180 close to the annular sealing seat 190, so that after the wire 150 is inserted into the mounting hole 183, the annular protrusion on the wire 150 can be located above the limiting protrusion and abut against the limiting protrusion, and the wire 150 is limited on one side of the sealing cover 180 close to the chassis 10 and does not fall off.
