When the first wiring body and the second wiring body are connected, the limiting protrusion is engaged in the limiting groove.

[0018] Compared with the prior art, the connector of the utility model has the following advantages:

[0019] 1. The utility model comprises a first wiring body, which comprises a first shell and a first pair of plug-ins arranged in the first shell; the first shell comprises a first cylinder, and a stopper is arranged on the inner wall of the first cylinder; the first pair of plug-ins comprises a main body and a clamping part connected to one end of the main body, the clamping part extends into the first cylinder, and the stopper abuts against one end of the clamping part away from the main body; the utility model further comprises a second wiring body, which comprises a second shell and a second pair of plug-ins at least partially arranged in the second shell, the second shell comprises a second cylinder, and the second pair of plug-ins comprises a plug-in part extending into the second cylinder; the first wiring body and the second wiring body are pluggable and connected, the second cylinder is sleeved on the outside of the first cylinder, the plug-in part extends into the first cylinder, and is clamped by the clamping part after extending through the stopper. The stopper abuts against one end of the clamping portion away from the main body to hinder the movement tendency of the clamping portion when the plug-in portion is plugged in or out, thereby limiting the inward or outward movement of the first pair of plug-ins relative to the first wiring body, effectively preventing the first pair of plug-ins from moving together with the second wiring body when the second wiring body is inserted or pulled out, thereby improving the internal structural stability of the first wiring body.

[0020] 2. The clamping part of the utility model includes two clamping arms, and the ends of the two clamping arms away from the main body are bent in opposite directions to form a tilted section; the inner wall of the first cylinder is provided with two stoppers corresponding to the two tilted sections, and the stoppers abut against the ends of the tilted sections away from the main body. By providing two clamping arms with one end tilted and the stoppers abutting against the clamping arms, the clamping part and the stoppers can occupy a smaller space inside the first cylinder while ensuring that the movement tendency of the first pair of plug-ins is hindered, so that the plug-in and pull-out of the plug-in part is reduced, and the plug-in part can be more easily clamped by the clamping arms of the clamping part, thereby improving the ease of plugging and unplugging of the connector and the reliability of the electrical connection between the first pair of plug-ins and the second pair of plug-ins.

[0021] 3. The two clamping arms and the two stoppers of the utility model define a channel for the plug-in and pull-out of the plug-in part. The stopper is inclined toward the channel and is on the same plane as the side of the tilting section toward the channel. By setting the internal channel of the first cylinder formed by the abutment of the clamping part and the stopper, when the first wiring body and the second wiring body are plugged in, the internal channel limits the insertion position of the plug-in part and always aligns it with the corresponding mating insertion position of the plug-in, preventing the second pair of plug-ins from being misplaced, thereby improving the ease of use of the connector when docking and the reliability of the electrical connection between the first pair of plug-ins and the second pair of plug-ins.

[0022] 4. The first housing of the utility model includes a first main body connected to the first cylinder, a wiring cavity is provided inside the first main body, and a groove is provided on the inner wall of the wiring cavity; the main body is provided in the wiring cavity, and a protrusion is provided on the side of the main body, and the protrusion is engaged in the groove. The protrusion provided on the side of the main body cooperates with the groove in the wiring cavity, thereby further limiting the displacement of the first pair of plug-ins during use.

[0023] 5. The wiring cavity of the utility model is provided with a spring sheet, which includes a connected clamping part and a tilting part, and the tilting part is in contact with the main body at one end away from the clamping part. When the external wire is connected, the tilting part cooperates with the main body to clamp the external wire. Through the cooperation of the tilting part and the main body, the external wire is connected to the first pair of plug-ins, and the clamping relationship makes it difficult for the external wire to slip outward, thereby improving the connection stability of the connector.

[0024] 6. The first wiring body of the utility model includes a pressing piece connected to the outer side of the first shell, the pressing piece includes a fixing part, a limiting column arranged below the fixing part, a pressing part, and a pressing column arranged below the pressing part. The first body is provided with a limiting hole and a pressing hole connected to the wiring cavity at corresponding positions of the limiting column and the pressing column; the limiting column can be movably inserted into the limiting hole; the pressing piece is pressed, and the pressing column passes through the pressing hole into the wiring cavity and abuts the tilting part. When it is necessary to connect the external wire to the first wiring body or pull it out, by pressing down the pressing part, the pressing column passes through the pressing hole into the wiring cavity and pushes away the tilted part of the spring sheet, so that the spring sheet and the first pair of plug-ins change from a contact state to a separated state, thereby loosening the clamped external wire and disconnecting the connection between the external wire and the first pair of plug-ins; in addition, through the cooperation between the limiting column provided on the fixing part and the limiting hole of the first main body, when operating the pressing part, the forward and backward displacement activity of the pressing piece caused by the pressing action can be limited, so that the pressing column is always aligned with the pressing position of the tilted part of the spring sheet, thereby preventing the problem of ineffective pressing and insufficient insertion of the external wire, effectively preventing the cause of insufficient connection stability, and greatly improving the stability of the connection.

[0025] 7. A clamping protrusion is provided on the side of the clamping part of the utility model, and a matching clamping groove is provided at the position corresponding to the clamping protrusion on the inner wall of the wiring cavity, and the clamping protrusion is clamped in the clamping groove. By providing the clamping protrusion clamped in the clamping groove, the possible forward and backward displacement of the spring piece when it is pressed by the pressing column, when the first pair of plug-ins has a tendency to move, and when the external wire moves is limited, thereby improving the stability of the internal structure of the first wiring body and the stability of the connection with the external wire.

[0026] 8. The first pair of plugs of the present utility model further includes a baffle disposed within the first main body, and the baffle extends from the main body portion towards the clamping portion. By providing the baffle within the first main body, it prevents the inserted peripheral wire from extending excessively into the wiring cavity, which may cause the processed conductive portion to fail, thereby improving the stability of the conductive structure.

[0027] 9. The second housing of the present utility model further includes a second main body communicating with the second cylinder and a fixing base fittingly connected to the second main body; the second pair of plugs includes a welding portion at least partially extending outside the second housing, and the shape of the welding portion is "L". Since the end of the welding portion needs to be connected to the peripheral wire by welding, the "L" shape design of the welding portion, while ensuring that the end passes through the second main body, greatly increases the contact area with the fixing base and the second main body, enabling the fixing base and the second main body to better support the second pair of plugs and restricting the displacement tendency generated when the second pair of plugs is docked or pulled out from the first pair of plugs, thereby greatly improving the internal structural stability of the second wiring body.

[0028] 10. The present utility model is provided with a limiting protrusion on the outer side of the first cylinder, and a limiting groove is provided at a position corresponding to the limiting protrusion on the second cylinder. When the first wiring body and the second wiring body are connected, the limiting protrusion and the limiting groove are in limiting cooperation with each other. Through the limiting cooperation of the limiting protrusion and the limiting groove, the user can more intuitively determine the positive and negative insertion relationship between the first wiring body and the second wiring body during use, preventing the occurrence of reverse insertion.

[0047] Moreover, in addition to being able to represent the orientation or positional relationship, some of the above terms may also be used to represent other meanings. For example, the term "upper" may also be used to represent a certain attachment relationship or connection relationship in some cases. For those of ordinary skill in the art, the specific meanings of these terms in the present utility model can be understood according to the specific circumstances.

[0048] In addition, the terms "installed", "set", "provided with", "connected", "linked" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral structure; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, or there is an internal connection between two devices, elements or components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to the specific circumstances.

[0049] Please refer to Figure 1 - Figure 2, the first embodiment of the present utility model provides a connector 1, which includes a first wiring body 2 and a second wiring body 3 that can be plugged and unplugged with the first wiring body 2; the first wiring body 2 includes a first housing 21 and a first pair of plug parts 22 arranged inside the first housing 21; the first housing 21 includes a first cylinder body 211, and a stop member 2111 is arranged on the inner wall of the first cylinder body 211; the first pair of plug parts 22 includes a main body part 221 and a clamping part 222 connected to one end of the main body part 221, the clamping part 222 extends into the first cylinder body 211, and the stop member 2111 abuts against the end of the clamping part 222 away from the main body part 221; the connector 1 further includes a second wiring body 3, the second wiring body 3 includes a second housing 31 and at least part of a second pair of plug parts 32 arranged inside the second housing 31, the second housing 31 includes a second cylinder body 311, and the second pair of plug parts 32 includes a plugging part 321 extending into the second cylinder body 311; the first wiring body 2 and the second wiring body 3 can be plugged and unplugged, the second cylinder body 311 is sleeved outside the first cylinder body 211, the plugging part 321 extends into the first cylinder body 211, and after passing through the stop member 2111, it is clamped by the clamping part 222.

[0050] It can be understood that when the first wiring body 2 and the second wiring body 3 are inserted into each other, the clamping part 222 clamps the plugging part 321; when the first wiring body 2 and the second wiring body 3 are pulled out relative to each other, the plugging part 321 separates from the clamping part 222, and the clamping part 222 generates a movement tendency in the same direction as the movement direction of the plugging part 321; by the stop member 2111 abutting against the end of the clamping part 222 away from the main body part 221, the stop member 2111 hinders the movement tendency generated by the clamping part 222 when the plugging part 321 is pulled out, so as to realize restricting the outward movement of the first pair of plug parts 22 relative to the first wiring body 2, effectively preventing the situation that the first pair of plug parts 22 may move together with the second wiring body 3 when the second pair of plug parts 32 is pulled out, thereby improving the internal structural stability of the first wiring body 2.

[0051] Specifically, in this embodiment, the first wiring body 2 is provided with three wiring points, and the second wiring body 3 is provided with three wiring points, and a total of three pairs of wires can be connected.

[0052] It can be understood that the shape of the clamping part 222 in this embodiment can be a structure that generates a plugging fit with the plugging part 321, including but not limited to clamping arms and connecting grooves.

[0053] It can be understood that the shape of the stop member 2111 in this embodiment can be a shape that generates an abutting fit with the clamping part 222, including but not limited to a columnar body, a block body, and a spherical body.

[0054] It can be understood that the inner diameter of the second cylinder 311 is equal to or slightly larger than the outer diameter of the first cylinder 211. When the first wiring body 2 and the second wiring body 3 are plugged together, the second cylinder 311 is sleeved on the outside of the first cylinder 211, and the plug-in portion 321 extends into the first cylinder 211 and is clamped by the clamping portion 222. At this time, the clamping portion 222 is electrically connected to the plug-in portion 321, that is, the first pair of plug-ins 22 and the second pair of plug-ins 32 are electrically connected.

[0055] See also Figure 2 and Figure 3 Furthermore, the clamping portion 222 includes two clamping arms 2221, and one end of the two clamping arms 2221 away from the main body 221 is bent in opposite directions to form a raised section 2222; two stoppers 2111 are provided on the inner wall of the first cylinder 211 corresponding to the two raised sections 2222, and the stoppers 2111 abut against one end of the raised section 2222 away from the main body 221.

[0056] It can be understood that the provision of the two clamping arms 2221 facilitates the clamping portion 222 to clamp the plug-in portion 321 to improve the stability of the connection, thereby improving the electrical connection stability of the first pair of plug-ins 22 and the second pair of plug-ins 32 .

[0057] It can be understood that the setting of the tilted section 2222 allows one end of the clamping arm 2221 to better abut against the stopper 2111, and the matching structure of the clamping arm 2221 and the stopper 2111 in the first cylinder 211 is more compact, thereby facilitating the plug-in portion 321 to extend into the first cylinder 211 and being more easily clamped by the clamping portion 222, thereby further improving the ease of plugging and unplugging of the connector 1 and the reliability of the electrical connection.

[0058] Furthermore, a channel 2223 for plugging and unplugging the plug-in portion 321 is defined between the two clamp arms 2221 and between the two stoppers 2111 . The stopper 2111 is inclined toward the channel 2223 and is on the same plane as the side of the tilting section 2222 toward the channel 2223 .

[0059] It can be understood that the channel 2223 limits the movement path of the plug-in portion 321 in the first cylinder 211, restricting the second pair of plug-ins 32 to always be aligned during insertion and only be inserted into the insertion position that cooperates with the two clamp arms 2221, preventing the plug-in portion 321 from being misplaced during insertion, thereby improving the ease of use of the connector 1 during docking and the reliability of the electrical connection between the first wiring body 2 and the second wiring body 3.

[0060] Please combine Figure 2 - Figure 5Furthermore, the first shell 21 includes a first main body 212 connected to the first cylinder 211, the first main body 212 includes a wiring terminal 2126 for connecting to an external wire, a wiring cavity 2121 is provided inside the first main body 212, and a groove 2122 is provided on the inner wall of the wiring cavity 2121; the main body 221 is provided in the wiring cavity 2121, and a protrusion 2211 is provided on the side of the main body 221, and the protrusion 2211 is snap-fitted into the groove 2122.

[0061] Specifically, the upper surface of the main body 221 is in contact with the inner wall of the wiring cavity 2121, and the protrusion 2211 on the side of the main body 221 is snapped into the groove 2122, so that the main body 221 is fixed on the inner wall of the wiring cavity 2121, thereby reducing the shaking of the first pair of plug-ins 22 and improving the stability of the internal structure.

[0062] As an optional embodiment, one end of the main body 221 away from the clamping portion 222 abuts against the solid part of the terminal 2126, so that when the first wiring body 2 and the second wiring body 3 are plugged together and the first pair of plug-ins 22 are subjected to a thrust and have a tendency to move, the terminal 2126 acts as a support to hinder the movement, thereby achieving the effect of limiting the inward movement of the first pair of plug-ins 22 relative to the first wiring body 2 and improving the internal structural stability of the first wiring body 2.

[0063] Furthermore, a spring piece 23 is disposed in the wiring cavity 2121 . The spring piece 23 includes a clamping portion 231 and a tilting portion 232 that are connected to each other. An end of the tilting portion 232 away from the clamping portion 231 is in contact with the main body 221 .

[0064] Specifically, the main body 221 is a processed conductive portion of the first pair of plug-ins 22 , and the peripheral wires are connected when in contact with the main body 221 , which is equivalent to the peripheral wires being electrically connected to the first pair of plug-ins 22 .

[0065] More specifically, when the external wire is connected to the first wiring body 2, the tilting portion 232 and the main body 221 cooperate with each other to clamp the inserted part of the external wire, making it difficult for the external wire to slip out due to the clamping relationship, thereby improving the connection stability of the connector 1.

[0066] Please combine Figure 2 - Figure 7Further, the first wiring body 2 includes a pressing piece 24 connected to the outer side of the first shell 21, the pressing piece 24 includes a fixing portion 241, a limiting column 242 arranged below the fixing portion 241, a pressing portion 243, and a pressing column 244 arranged below the pressing portion 243. The first main body 212 is provided with a limiting hole 2124 and a pressing hole 2125 connected to the wiring cavity 2121 at corresponding positions of the limiting column 242 and the pressing column 244; the limiting column 242 can be movably inserted into the limiting hole 2124; the pressing piece 24 is pressed, and the pressing column 244 passes through the pressing hole 2125 to enter the wiring cavity 2121 and abuts against the tilting portion 232.

[0067] As an optional embodiment, a connecting hole 2212 is opened in the main body 221. After the pressing column 244 passes through the pressing hole 2125 and enters the wiring cavity 2121, it continues to pass through the connecting hole 2212 and then abuts against the tilting portion 232, so that there is a larger contact area between the pressing column 244 and the tilting portion 232, making it easier to press the pressing column 244.

[0068] It can be understood that the pressing piece 24 works as a switch to open the access entrance of the external wire; when the external wire needs to be connected to the first wiring body 2, by pressing down the pressing part 243, the pressing column 244 passes through the pressing hole 2125 into the wiring cavity 2121, and pushes away the tilting part 232 of the spring sheet 23, so that the spring sheet 23 and the first pair of plug-ins 22 change from a contact state to a separated state, and a wiring channel for the external wire to be connected is formed between the two. After the external wire is inserted, the pressing piece 24 is released, the pressing part 243 and the pressing column 244 return to the initial position, and the part of the tilting part 232 that is pushed away re-contacts the main body 221 and clamps the external wire, thereby realizing the electrical connection between the external wire and the first pair of plug-ins 22.

[0069] It can be understood that the operation of disconnecting the peripheral device wire from the first wiring body 2 is similar to the above-mentioned connection operation.

[0070] More specifically, the limiting column 242 is arranged between two adjacent pressing parts 243 and can be movably inserted into the limiting hole 2124. The limiting hole 2124 fixes the limiting column 242 in the limited space of the wiring cavity 2121, thereby achieving the effect of limiting the movement of the pressing member 24 when the pressing part 243 is operated, so that the pressing column 244 is always aligned with the pressing position of the tilting part 232, preventing the problem of poor pressing and insufficient insertion of the external wire, effectively preventing the cause of insufficient connection stability, and greatly improving the stability of the connection.

[0071] Furthermore, a clamping protrusion 2311 is provided on the side of the clamping portion 231 , and a clamping groove 2123 matching with each other is provided on the inner wall of the wiring cavity 2121 at a position corresponding to the clamping protrusion 2311 , and the clamping protrusion 2311 is clamped in the clamping groove 2123 .

[0072] Specifically, one side of the clamping portion 231 away from the main body portion 221 is attached to the inner wall of the wiring cavity 2121, and the clamping portion 231 is fixed to the inner wall of the wiring cavity 2121 through the clamping relationship between the clamping protrusion 2311 and the clamping groove 2123.

[0073] It can be understood that by setting the clamping relationship between the clamping portion 231 and the wiring cavity 2121, the movement tendency generated when the elastic piece 23 deforms under the push of the pressing column 244 is hindered, preventing the elastic piece 23 from shifting; in addition, in addition to the push of the pressing column 244, when the first pair of plug-ins 22 are inserted and removed from the second pair of plug-ins 32 and the peripheral wire moves, the force acting on the elastic piece 23 and causing the front and back movement tendency of the elastic piece 23 can also be effectively hindered, thereby improving the stability of the internal structure of the first wiring body 2 and the stability of the connection with the peripheral wire.

[0074] Furthermore, the first pair of plug-ins 22 further includes a retaining piece 223 disposed in the first main body 212, and the retaining piece 223 extends from the main body portion 221 to the clamping portion 231.

[0075] Specifically, the retaining piece 223 limits the contact range when the peripheral wire extends into the wiring cavity 2121, preventing the inserted peripheral wire from extending excessively into the wiring cavity 2121 and causing the processed conductive part to fail.

[0076] Specifically, the retaining piece 223 can be disposed on the inner wall of the first pair of plug-ins 22 or the wiring cavity 2121; in this embodiment, the retaining piece 223 is disposed on the main body portion 221 of the first pair of plug-ins 22, effectively restricting the situation where the peripheral wire extends to a position outside the conductive part.

[0077] Please refer to Figure 2 、 Figure 8 and Figure 9 . Furthermore, the second housing 31 further includes a second main body 312 communicated with the second cylinder 311 and a fixing seat 313 attached to and connected with the second main body 312; the second pair of plug-ins 32 includes a welding portion 322 at least partially extending outside the second housing 31, and the shape of the welding portion 322 is "L" shaped.

[0078] Specifically, one end of the "L" shape of the welding portion 322 is located in the groove body opened in the second main body 312, and the other end is clamped by the second main body 312 and the fixing seat 313 and passes through the second main body 312.

[0079] It can be understood that one end of the welding portion 322 passing through the second main body 312 can be connected to the peripheral wire by welding, so as to achieve the effect of electrically connecting the second pair of plug-ins 32 with the peripheral wire.

[0080] Understandably, when the second pair of plugs 32 are docked with or pulled out from the first pair of plugs 22, they generate a backward or forward movement tendency. The welding parts 322 respectively hinder their own movement through the abutting relationship with the fixed seat 313 and the second main body 312, thereby improving the internal structural stability of the second wiring body 3.

[0081] Please refer to Figure 6 - Figure 9 , furthermore, a limiting protrusion 2112 is provided on the outer side of the first cylinder body 211, and a limiting groove 3111 is provided at a position corresponding to the limiting protrusion 2112 on the second cylinder body 311. When the first wiring body 2 and the second wiring body 3 are connected, the limiting protrusion 2112 is snapped into the limiting groove 3111.

[0082] Understandably, the limiting protrusion 2112 limits the positive and negative plugging relationship of the first wiring body 2, enabling the first wiring body 2 to be inserted into the second wiring body 3 only through the positions of the limiting protrusion 2112 and the limiting groove 3111, intuitively and effectively preventing the occurrence of reverse connection and improving the use safety of the connector 1.

[0083] As an optional implementation manner, the connector 1 is provided with limiting protrusions 2112 only on the outer sides of two of the first cylinder bodies 211, and corresponding limiting grooves 3111 are provided on two corresponding second cylinder bodies 311.

[0084] Compared with the prior art, the connector of the present utility model has the following advantages:

[0085] 1. The connector of the present utility model includes a first wiring body, which includes a first outer shell and a first pair of plugs arranged inside the first outer shell; the first outer shell includes a first cylinder body, and a stop member is provided on the inner wall of the first cylinder body; the first pair of plugs includes a main body portion and a clamping portion connected to one end of the main body portion, the clamping portion extends into the first cylinder body, and the stop member abuts against the end of the clamping portion away from the main body portion; the connector further includes a second wiring body, which includes a second outer shell and at least part of a second pair of plugs arranged inside the second outer shell, the second outer shell includes a second cylinder body, and the second pair of plugs includes a plugging portion extending into the second cylinder body; the first wiring body and the second wiring body are pluggable, the second cylinder body is sleeved outside the first cylinder body, the plugging portion extends into the first cylinder body, and after passing through the stop member, it is clamped by the clamping portion. By the stop member abutting against the end of the clamping portion away from the main body portion, the movement tendency generated by the clamping portion during the plugging and unplugging of the plugging portion is hindered, thereby achieving the effect of restricting the inward or outward movement of the first pair of plugs relative to the first wiring body, effectively preventing the situation that the first pair of plugs may move together with the second wiring body when the second wiring body is inserted or pulled out, and thus improving the internal structural stability of the first wiring body.

[0086] 2. The clamping part of the utility model includes two clamping arms, and the ends of the two clamping arms away from the main body are bent in opposite directions to form a tilted section; the inner wall of the first cylinder is provided with two stoppers corresponding to the two tilted sections, and the stoppers abut against the ends of the tilted sections away from the main body. By providing two clamping arms with one end tilted and the stoppers abutting against the clamping arms, the clamping part and the stoppers can occupy a smaller space inside the first cylinder while ensuring that the movement tendency of the first pair of plug-ins is hindered, so that the plug-in and pull-out of the plug-in part is reduced, and the plug-in part can be more easily clamped by the clamping arms of the clamping part, thereby improving the ease of plugging and unplugging of the connector and the reliability of the electrical connection between the first pair of plug-ins and the second pair of plug-ins.

[0087] 3. The two clamping arms and the two stoppers of the utility model define a channel for the plug-in and pull-out of the plug-in part. The stopper is inclined toward the channel and is on the same plane as the side of the tilting section toward the channel. By setting the internal channel of the first cylinder formed by the abutment of the clamping part and the stopper, when the first wiring body and the second wiring body are plugged in, the internal channel limits the insertion position of the plug-in part and always aligns it with the corresponding mating insertion position of the plug-in, preventing the second pair of plug-ins from being misplaced, thereby improving the ease of use of the connector when docking and the reliability of the electrical connection between the first pair of plug-ins and the second pair of plug-ins.

[0088] 4. The first housing of the utility model includes a first main body connected to the first cylinder, a wiring cavity is provided inside the first main body, and a groove is provided on the inner wall of the wiring cavity; the main body is provided in the wiring cavity, and a protrusion is provided on the side of the main body, and the protrusion is engaged in the groove. The protrusion provided on the side of the main body cooperates with the groove in the wiring cavity, thereby further limiting the displacement of the first pair of plug-ins during use.

[0089] 5. The wiring cavity of the utility model is provided with a spring sheet, which includes a connected clamping part and a tilting part, and the tilting part is in contact with the main body at one end away from the clamping part. When the external wire is connected, the tilting part cooperates with the main body to clamp the external wire. Through the cooperation of the tilting part and the main body, the external wire is connected to the first pair of plug-ins, and the clamping relationship makes it difficult for the external wire to slip outward, thereby improving the connection stability of the connector.

[0090] 6. The first wiring body of the utility model includes a pressing piece connected to the outer side of the first shell, the pressing piece includes a fixing part, a limiting column arranged below the fixing part, a pressing part, and a pressing column arranged below the pressing part. The first body is provided with a limiting hole and a pressing hole connected to the wiring cavity at corresponding positions of the limiting column and the pressing column; the limiting column can be movably inserted into the limiting hole; the pressing piece is pressed, and the pressing column passes through the pressing hole into the wiring cavity and abuts the tilting part. When it is necessary to connect the external wire to the first wiring body or pull it out, by pressing down the pressing part, the pressing column passes through the pressing hole into the wiring cavity and pushes away the tilted part of the spring sheet, so that the spring sheet and the first pair of plug-ins change from a contact state to a separated state, thereby loosening the clamped external wire and disconnecting the connection between the external wire and the first pair of plug-ins; in addition, through the cooperation between the limiting column provided on the fixing part and the limiting hole of the first main body, when operating the pressing part, the forward and backward displacement activity of the pressing piece caused by the pressing action can be limited, so that the pressing column is always aligned with the pressing position of the tilted part of the spring sheet, thereby preventing the problem of ineffective pressing and insufficient insertion of the external wire, effectively preventing the cause of insufficient connection stability, and greatly improving the stability of the connection.

[0091] 7. A clamping protrusion is provided on the side of the clamping part of the utility model, and a matching clamping groove is provided at the position corresponding to the clamping protrusion on the inner wall of the wiring cavity, and the clamping protrusion is clamped in the clamping groove. By providing the clamping protrusion clamped in the clamping groove, the possible forward and backward displacement of the spring piece when it is pressed by the pressing column, when the first pair of plug-ins has a tendency to move, and when the external wire moves is limited, thereby improving the stability of the internal structure of the first wiring body and the stability of the connection with the external wire.

[0092] 8. The first pair of plug-ins of the utility model also includes a baffle plate arranged in the first body, and the baffle plate extends from the main body to the clamping part. By arranging the baffle plate in the first body, it is prevented that the connected external wires are excessively extended into the wiring cavity, causing the processed conductive parts to fail, thereby improving the stability of the conductive structure.

[0093] 9. The second housing of the utility model also includes a second main body connected to the second cylinder and a fixing seat connected to the second main body; the second pair of plug-ins includes a welding portion that at least partially extends outside the second housing, and the shape of the welding portion is "L". Since the end of the welding portion needs to be connected to the external wire by welding, the "L"-shaped design of the welding portion greatly increases the contact area with the fixing seat and the second main body while ensuring that the end passes through the second main body, so that the fixing seat and the second main body can better support the second pair of plug-ins, and limit the displacement tendency of the second pair of plug-ins when docking or pulling out with the first pair of plug-ins, which greatly improves the internal structural stability of the second wiring body.

[0094] 10. The utility model is provided with a limiting protrusion on the outer side of the first cylinder body, and the second cylinder body is provided with a limiting groove at a position corresponding to the limiting protrusion. When the first wiring body and the second wiring body are connected, the limiting protrusion and the limiting groove are in mutual limiting cooperation. Through the limiting cooperation of the limiting protrusion and the limiting groove, users can more intuitively determine the positive and negative insertion relationship between the first wiring body and the second wiring body during use, preventing the occurrence of reverse insertion.

[0095] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, and improvements made within the principles of the present utility model shall be included within the protection scope of the present utility model.
