Example execution 1

[0114] As illustrated in Figures 1 to 28, the invention provides a plug-in connector 100, comprising a first connection terminal 200 and a second connection terminal 300. The first terminal 200 is equipped with a first inlet port 210 and a first opening 220, which is provided with a socket cap 1 for closing. The socket cap 1 has a connection part 11 extending in the direction of the inlet port 210. The second terminal 300 has a second inlet port 210' and a second opening 220', which is closed by a part cap 7, which includes a connection part 71 extending in the direction of the second inlet port. The socket cap 1 and part cap 7 are made of insulating material.The first wire entry hole 210' and the second wire entry hole 220' are arranged in opposite position, the plug cap 11 and the socket cap 71 cooperate to enable a detachable connection between the first connection terminal 200 and the second connection terminal 300.

[0115] As illustrated in FIGS. 6 to 9, in the aforementioned scenario, by arranging the first connection terminal 200 and the second connection terminal 300, at least two conductors can be inserted through the first wire entry hole 210 and the second wire entry hole 220' into the conductor accommodation cavities of the first connection terminal 200 and the second connection terminal 300; the first connection terminal 200 and the second connection terminal 300 can be detachably connected via the plug cap 11 and the socket cap 71, thereby enabling the conduction of at least two conductors. The cooperation of the plug cap 1 and the socket cap 77 can prevent the incorrect insertion of the conductors.

[0116] In this exemplary implementation, the socket cap 1 comprises a cap body which consists of a socket base 12 and the connection part 11. The socket base 12 is fixedly installed at the location of the first opening 220. It comprises an upper surface and a first connection surface 13 connected to the front end of the upper surface. The first connection surface 13 has a through hole corresponding to the first inlet hole 210, while the connection part 11 is located at this hole. This connection part 11 has a generally hollow column-shaped structure, which communicates with the first inlet hole via the hole on the first connection surface 13. The part cap 7 is also attached to the second opening 220', and the part base 72 comprises an upper surface and a second connection surface 73, which is connected to the front end of the upper surface. The second connection surface 73 is equipped with a through hole corresponding to the second inlet hole 210'.

[0117] In the aforementioned scenario, locking mechanisms are provided on the plug cap 1 and the socket cap 77 to maintain the connection state of the plug 11 and socket 71 connection parts in place. More specifically, the connection part 11 may have a hollow columnar structure, but is not limited to this; it may also be a hollow cylinder or take other shapes suitable for assembly with the connection part 71, such as a cylindrical structure having a non-circular cross-section. In addition, the locking mechanism may include one or more reinforcements 714, located on the outer wall of the connection part 71, extending in the length direction of this part. It may also include grooves 112 on the connection part 11, which are adapted to fit with the reinforcements 714.The socket connection part 71 is inserted into the plug connection part 11, and the combined action of the locking mechanism ensures a more stable installation of the plug caps 1 and socket caps 7.

[0118] In the above-mentioned example, the attachment of the plug connection portion 11 and the socket connection portion 71 is reinforced by a snap-in component. In detail, the locking assembly may comprise an arm-shaped holding member 716, which extends from the second connection surface 73 in the direction of the inlet port 210', as well as a holding notch 116 located on the upper part of the connection portion 11. When the first terminal 200 engages with the second terminal 300, the arm-shaped holding member 716 engages and attaches to the holding notch 116. The presence of the snap-in component ensures a more secure connection between the plug connection portion 11 and the socket connection portion 71, and effectively prevents misconnections.

[0119] In addition, the protruding end of the cantilever 716 is provided with an upward notch 717 which engages in the retaining notch 116 for additional support. In addition, the hooked portion 717 is provided with an anti-slip strip 718, providing an obvious support point when unlocking the 100 plug connector, while providing a non-slip function for convenient use.

[0120] As illustrated in Figures 10 to 13 of this example, the connection terminal 200 also comprises a connection terminal outer housing 2, which, by assembling on the left and right sides, forms a first body with the plug cap 1 at the first opening 220; similarly, the connection terminal 300 comprises a connection terminal outer housing 2', which, by assembling on the left and right sides, forms a second body with the socket cap 7 at the second opening 220'.

The first connecting element 251 or the second connecting element 261 is adapted to removably assemble with the second connecting element 261 or the first connecting element 251 of another terminal housing 2, thus making it possible to connect several first terminal housings 2 in pairs. The outer housing of the second connection terminal 2' is structured in the same way as the outer housing of the first connection terminal 2.

[0125] In this context, the third side 25' of the outer housing of the second connection terminal 2' is provided with a third connecting portion 251', and the fourth side 26' of the outer housing of the second connection terminal 2' opposite the third side 25' has a fourth connecting portion 261' corresponding to the third connecting portion 251'.

Optionally, the plug clamping spring, the plug connector 42 and the pin head 42 can also be fixed by welding, gluing, etc., this embodiment according to the invention does not impose any restriction in this regard. It is understandable that the integration mode improves the connection strength of the plug clamping device 4 in order to strengthen the overall structure of the first connection terminal 200.

[0129] In the foregoing context, the connection modes of the socket clamping spring 81, the socket connector 82, and the pin sleeve 83 may vary. Similarly, the connector holding spring 81, the connector 82, and the pin sleeve 83 may also be formed as a single piece, or the connector 82 and the pin sleeve 83 may be formed together. Optionally, the socket clamping spring 81, the socket connector 82, and the pin sleeve 83 may also be fixed by welding, gluing, etc., this embodiment according to the invention does not impose any restriction in this regard. It is understandable that the integration mode improves the connection strength of the socket clamping device 8 to strengthen the overall structure of the second connection terminal 200.

[0130] In the mentioned implementation example, the plug clamping spring 4 is composed of a plug front metal piece 413 and a plug bus bar 415. The plug front metal piece comprises two plug elastic pieces 413 arranged in parallel and a plug fixing piece 414 which connects the two plug elastic pieces 413 together. One side of the plug elastic piece 413 is connected to the plug fixing piece 414.

[0131] In the mentioned implementation example, the clamping spring of the connector 8 is composed of a front metal part of the connector 813 and a bus bar of the connector 815. The front metal part of the connector comprises two elastic parts of the connector 813 arranged in parallel and a fixing part of the connector 814 which connects the two elastic pieces of connector 813 together. One side of the elastic piece of connector 813 is connected to the connector fixing piece 814. The bus bar is inverted Z-shaped, the base 817 of the connector bus bar is firmly connected to the base of the front metal piece of the connector. The upper part of the connector bus bar has a connector piece-shaped projection 812. The connector spring is generally V-shaped, including a fixing edge 818 and a bearing edge 811. The fixing edge 814 of the front metal piece of the connector is located at the bottom of the connector bus bar and is in close contact with the base 817 of the connector bus bar. Preferably, the elastic piece of connector 813 is connected to one end of the connector 82 by a curved surface or an elastic arc portion, etc.The upper portion of the elastic part of the connector 813 has a connector groove 818, located on each side of the elastic part of the connector 813, to facilitate the placement of the disconnection device 3'.

[0132] In this exemplary implementation, the connector 42 may have, but is not limited to, a trapezoidal plate-shaped structure for establishing the connection between the collector bundle and the pin header, where this connector 42 may be integrally formed with the collector bundle. The connector 82 may also have a trapezoidal plate structure for connecting the metal plate 815 of the rear connection element to the pin sleeve 83.

[0133] In the mentioned implementation example, the side wall of the pin sleeve 83 is provided with positioning protrusions 831. Optionally, the positioning protrusions 831 can be stacked and placed on both sides of the pin sleeve 83, enhancing the insertion and removal force of the connector.

[0134] In the mentioned implementation example, the pin sleeve 83 is provided with an expandable slot 833 passing through the wall of the tube. In order to facilitate expansion during insertion and removal of the pin head 42, the pin sleeve 83 also has an expandable slot 832 that does not completely pass through the wall of the socket, which makes the pin sleeve 83 more elastic. In addition, the pin sleeve 83 may be, without limitation, of a hollow structure.

[0135] In the above-mentioned implementation example, the pin head 42 may be, without limitation, cylindrical in shape. The upper portion of the pin head 42 is provided with a telescopic joint 431, the width of which gradually narrows towards the pin hole, thus imparting elasticity to the pin head 42. This ensures flexibility and elasticity when connecting the interconnect, minimizing the risk of deformation during installation. Of course, the pin head 42 and the pin sleeve 83 may also be designed without cracks or cutouts, while maintaining a certain elasticity.

One end of the support arms 32 is connected to the connecting arm 31, the other end of the support arms 32 is free and enters the outer housing of the first connecting terminal 2 to compress the clamping spring of the connector. The position of the end of the connecting arm 31 is provided with anti-slip ridges to facilitate pivoting or lifting of the first disconnecting device during manual operation. Ideally, the front sides of the end of the connecting arm 31 can be tightened inward.The bottom of the support wall is triangular in shape, with a first triangular support projecting inside the support wall, and a second support 35 located on the upper part of the first support 34. The first support 34 cooperates with the groove 418 of the elastic plate 413 of the connector, while the second support 35 contacts the edges of the blanks of the first plate 221 on each side.

[0138] When the holding interface of the holding device 4 is in the closed position, the first connecting arm 31 of the stripping device is either horizontal or close to horizontal. By activating the first connecting arm 31, the first support 34 contacts the groove 418 of the elastic plate 413, while the second support 35 contacts the edges of the blanks of the first plate 221. As the disconnection prevention device rotates, the first support 34 gradually compresses the elastic plate, thereby further opening the holding interface. When the connector is in the open position, the first support 34 is in contact with the groove 418 of the elastic plate.

[0139] In the aforementioned implementation example, the disconnection device 3' comprises the second connection arm 31' and two second support arms 32' arranged in opposition and connected to the second connection arm 31'.

[0140] When the clamping interface of the connector clamping device 8 is in the closed position, the second connecting arm 31' of the disconnecting device 3' is horizontal or nearly horizontal. By pivoting the second connecting arm 31' of the disconnecting device 3', the third support 34' contacts the connector tab 813 in the recess of the tab, and the fourth support 35' contacts the flange. By rotating the anti-disconnecting device, the third support 34' gradually compresses the tab to further open the clamping interface. When the connector is in the open position, the third support 34' is in contact with the recess of the connector.

[0141] In this implementation, the connector pressure cover 1 is equipped with a connector test port 14, and / or the connector insertion cap is equipped with at least one connector test port 74. In addition, the connector test ports 14 and 74 may be located at the upper level of the connector socket 12 to facilitate conductivity detection.

[0142] As illustrated in Figures 22 to 25, in this implementation, the plug-in connector also comprises a cable protection box 400, comprising an upper cover 5 and a lower base 6, the upper cover 5 being hinged to the lower base 6. In addition, the size of the cable protection box is larger than that of the first connection terminal 200 and the second connection terminal 300, and the first connection terminal 200 and the second connection terminal 300 are respectively mounted in the two cable protection boxes to protect the cables.

[0143] As described in Figures 22 to 25, a positioning space 410 is formed between the lower base 6 and the upper cover 5 for positioning the first connection terminal 200 or the second connection terminal 300, and in front of the positioning space 410 is a plug-in slot 420 for the first connection terminal 200 or the second connection terminal 300 for plug-in or insertable connection. In addition, a through hole 430 is provided at the rear of the positioning space 410 to allow cables to pass outside.

[0144] In the above example, the connector pressure cover 1 also includes an insertion cap locking slot 15 located at the end of the connector socket, and the receptacle pressure cover 7 also includes an insertion cap locking slot 75 located at the end of the receptacle. The top cover 5 includes a top cover wall 52 and two top cover side walls 53 connected to the top cover wall 52.

[0145] In the above example, the back of the upper cover wall 52 is equipped with an insertion hole 521, and a cable clamp 54 is fixed to the back of the insertion hole 521 of the upper cover wall, the cable clamp 54 comprises a connecting segment 541 and a lever segment 542, the connecting segment 541 is fixed to the back of the insertion hole 521 of the upper cover wall, and the lever segment 542 extends into the upper cover groove 531 to elastically fit the conductive wire through the hole 430. It is understood that the lever segment 542 is elastic, which enables it to automatically clamp wires of different sizes by virtue of its own elasticity.

[0146] In the above example, the lever segment 542 is bent into a hook shape. Specifically, the lever segment 542 bends backward and curves toward the insertion direction of the conductive wire to contact the conductive wire. The bending design of the lever arm segment can enhance the strength of the cable clamp 54 and, at the same time, ensure more stable fixation of the wires inserted into the junction box.

[0147] In this example, the front ends of the upper cover 5 are equipped with a rotation axis 51, and the front ends of the lower base 6 are provided with fixing arms 61 compatible with the rotation axis 51. More precisely, the rotation axis 51 is connected to the hooks of the fixing arms. When the upper cover 5 is open, the connection terminals 200 or 300 can be installed in the junction box 400; when the upper cover 5 is closed, the connection terminals 200 or 300 are locked inside the junction box 400. Ideally, the end of the rotation axis 51 can be provided with a letter-shaped locking pin, facilitating the installation of the connection terminals 200 or 300 when the junction box 400 is open. When the upper cover 5 is closed, the junction box 400 ensures the stability and safety of the use of the connection terminals 200 or 300.

The front end of the lateral sides 63 is provided with a groove 631 for the location of the first connection terminals 200 and the second connection terminals 300. The center of the bottom base 62 is equipped with a connection hole 621, which has an elastic locking device 66. When the first or second connection terminals 200 / 300 are inserted into the groove 631, the locking device 66 is responsible for holding these terminals in place to prevent any movement.

[0149] In this embodiment, the cable protection box 400 comprises a locking component, which includes a fixing piece 67 located at the rear of the lower base 6. The fixing piece 67 has the structure of a longitudinal strip-shaped plate, extending upward from the base of the lower base 62 along the side wall of the base 63. The end of the fixing piece 67 is equipped with a hook, and the rear of the side wall of the upper cover 53 is provided with a connection slot, at the level corresponding to the piece 67, capable of engaging the lock therewith. It is understandable that the locking component can make the use of the cable protection box more secure.

[0150] The fixing piece 67 is connected to the base of the lower base 62, at which there are two transverse bars which pass through said base of the base 62. When the cover and the base are closed, these bars make it easier to fix the cable.

[0151] In this embodiment, the outer side of the side wall of the lower base 63 is provided with non-slip patterns 65. The non-slip patterns 65 can play an anti-slip role during assembly and use.
