Example of execution 1

[0114] As illustrated in Figures 1 to 28, the invention provides a pluggable 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 fitted with a plug cap 1 for closure. The plug cap 1 has a connection portion 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 cap 7, which includes a connection portion 71 extending in the direction of the second inlet port. The plug caps 1 and 7 are made of insulating material.The first wire entry hole 210' and the second wire entry hole 220' are arranged in opposite positions, the plug cap 11 and the socket cap 71 cooperate to allow a detachable connection between the first connection terminal 200 and the second connection terminal 300.

[0115] As illustrated in Figures 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 housing 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 by means of the plug cap 11 and the socket cap 71, thus allowing the conduction of at least two conductors. The cooperation of the plug cap 1 and the socket cap 77 can prevent incorrect insertion of the conductors.

[0116] In this implementation example, the socket cap 1 comprises a cap body consisting of a socket base 12 and the connection portion 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 portion 11 is located at this hole. This connection portion 11 generally has a 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 present on the plug cap 1 and the socket cap 77 to maintain the connection of the plug connection parts 11 and 71. More specifically, the connection part 11 may have a hollow column structure, but is not limited to this; it may also be a hollow cylinder or take other forms suitable for assembly with the connection part 71, such as a cylindrical structure having a non-circular cross-section. Furthermore, the locking mechanism may include one or more reinforcements 714, located on the outer wall of the connection part 71, extending along the length of that part. It may also include grooves 112 on the connection part 11, which are designed 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 aforementioned example, the connection between the plug connection portion 11 and the socket connection portion 71 is reinforced by a snap-on component. Specifically, the locking assembly may include an arm-shaped retaining element 716, extending from the second connection surface 73 in the direction of the inlet port 210', and a retaining notch 116 located on the upper part of the connection portion 11. When the first terminal 200 interlocks with the second terminal 300, the arm-shaped retaining element 716 engages and locks into the retaining notch 116. The snap-on component ensures a more secure connection between the plug connection portion 11 and the socket connection portion 71, and effectively prevents incorrect connections.

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

[0120] As illustrated in Figures 10 to 13 of this example, the connection terminal 200 also includes an external connection terminal housing 2, which, when assembled 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 includes an external connection terminal housing 2', which, when assembled on the left and right sides, forms a second body with the plug cap 7 at the second opening 220'. One end of the external connection terminal housing 2 is for the wire entry hole 210, and the other is connected to the plug socket 12 through the first opening 220; Similarly, one end of the 2' external terminal housing is for the 210' wire entry hole, and the other is connected to the 72 plug socket through the second 220' opening. The 2' and 2' external terminal housings have a similar structure.

[0121] In this example, the top of the external terminal housing 2 has a locking tab component 22 extending from the upper end of the wire entry hole 210 to the rear of the external terminal housing 2, comprising at least two locking tabs 221 attached to the upper end of the wire entry hole 210, inserted into the plug cap 1 for secure attachment.

[0122] The top of the outer housing of the second connection terminal 2' consists of a set of second connection plates 22', extending from the top of the second entry hole 210' towards the rear of the outer housing of the second connection terminal 2'.

Similarly, the upper part of the connection socket 72 is provided with a corresponding slot for the ends of the second plates 221'.The fixing of the first plates 221 in their respective slots, as well as that of the second plates 221', can be carried out by various methods including, but not limited to, interlocking assembly, adhesive fixing, ultrasonic welding or fixing by means of a snap-fit ​​component.

[0123] In the example described above, the external housing of the first connection terminal 2 is attached to the plugin socket 12 by a first snap-fit ​​system; and / or the external housing of the second connection terminal 2' is connected to the socket connection 72 by a second snap-fit ​​system. The first snap-fit ​​system includes a lower locking protrusion 24 located on the underside of the outer housing of the first connection terminal 2, which rises, and a lower locking notch 122 located at the bottom of the plug socket 12, designed to engage and tighten the lower locking protrusion 24. Similarly, the first snap-fit ​​system includes an upper locking protrusion 23 located on the upper part of the first connection plate 221, which rises, and an upper locking notch 121 located at the top of the plug socket 12, designed to engage and tighten the upper locking protrusion 23.The second snap-fit ​​system includes a lower locking protrusion 24' located on the underside of the outer housing of the second connection terminal 2', which rises, and a lower locking notch 722 located at the bottom of the connection socket 72, designed to engage and clamp the lower locking protrusion 24'. Similarly, the second snap-fit ​​system includes an upper locking protrusion 23' located on the upper portion of the second connection plate 221', which rises, and an upper locking notch 721 located at the top of the connection socket 72, designed to engage and clamp the upper locking protrusion 23'. More specifically, the first connection plate 221 inserts into the slot of the plug socket 163, while the second connection plate 221' inserts into the slot of the connection socket 763.The plug cap 1 connects to the external housing of the first connection terminal 2, while the socket cap 7 attaches to the external housing of the second connection terminal 2', thus ensuring a secure assembly.

[0124] In this implementation example, a first linking element 251 is located on the first side 25 of the housing of the first terminal 2, while a second linking element 261, corresponding to the first linking element 251, is present on the second side 26, which is opposite the first. The first linking element 251 or the second linking element 261 is designed to be removably assembled with the second linking element 261 or the first linking element 251 of another terminal 2 housing, thus allowing several first terminal 2 housings to be linked in pairs. The external housing of the second connection terminal 2' is structured in the same way as the external 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 part 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 part 261' corresponding to the third connecting part 251'. The third connecting part 251' or the fourth connecting part 261' the external housing of the second connection terminal 2' is designed to connect detachably to the fourth linking part 261' or the third linking part 251' of the external housing of another second connection terminal 2", thus allowing the external housing of the second connection terminal 2' to be connected in series with another external housing of the second connection terminal 2".

[0126] In the implementation example described above, the first connecting element 251 includes a first protruding part 252 which extends parallel to the insertion direction and which overhangs the first side 25 in the form of a U. The second connecting element 261 has a second groove 262 which is recessed into the second side 26, also parallel to the insertion direction, thus allowing the first protruding part 252 to be inserted into the second groove 262 of another terminal housing.

[0127] As illustrated in Figures 9 to 13, in this example, the first connection terminal 200 also includes a plug clamping device 4, mounted in the space formed between the plug cover 1 and the outer housing of the first connection terminal 2. The plug clamping device 4 includes a plug clamping spring 41, a plug connector 42, and a pin head 43 connected in sequence. The plug clamping spring 41 associates with the first entry hole 210 to form a first clamping interface; and the second connection terminal 300 also includes a socket clamping device 8, mounted in the space formed between the socket cover 7 and the outer housing of the second connection terminal.The plug clamping device 8 comprises a plug clamping spring 81, a plug connector 82, and a pin sleeve 83 connected in sequence, with the plug clamping spring 81 associating with the second entry hole 210' to form a second clamping interface. When the first connection terminal 200 abuts the second connection terminal 300, the pin head 42 engages with the pin sleeve 83 to provide a detachable connection between the first connection terminal 200 and the second connection terminal 300. More specifically, the plug clamping device 4 and the plug clamping device 8 are made of conductive metallic materials. At least two wires enter the plug connector from the first entry hole 210 and the second entry hole 210', connecting to the first and second clamping interfaces, respectively.The pin head 42 engages with the pin sleeve 83, thereby making both cables conductive, allowing even shorter cables to interconnect through the plug connector.

[0128] In the example above, the connection methods of the retaining spring of the plug 41, the plug connector 42, and the pin head 43 can vary. For example, the retaining spring 41, the connector 42, and the pin head 43 can be formed in a single piece, or the connector 42 and the pin head 43 can be integrated into a single element. Optionally, the plug clamping spring, the plug connector 42, and the pin head 42 can also be fixed by welding, bonding, etc.; this embodiment according to the invention does not impose any restrictions in this respect. It is understandable that the integration method improves the connection strength of the plug clamping device 4 in order to reinforce the overall structure of the first connection terminal 200.

[0129] In the preceding context, the connection methods for the clamping spring of the socket 81, the socket connector 82, and the pin sleeve 83 can vary. Similarly, the retaining spring of the connector 81, the connector 82, and the pin sleeve 83 can also be formed as a single piece, or the connector 82 and the pin sleeve 83 can be formed together. Optionally, the clamping spring of the socket 81, the socket connector 82, and the pin sleeve 83 can also be fixed by welding, bonding, etc. This embodiment according to the invention does not impose any restrictions in this respect. It is understandable that the integration method improves the connection strength of the socket clamping device 8 in order to reinforce the overall structure of the second connection terminal 200.

[0130] In the aforementioned implementation example, the clamping spring of the plug 4 consists of a front metal piece of the plug 413 and a plug busbar 415. The front metal piece of the plug comprises two parallel elastic pieces of the plug 413 and a plug retaining piece 414 that connects the two elastic pieces of the plug 413 together. One side of the elastic piece of the plug 413 is connected to the retaining piece of the plug 414. The busbar is in the shape of an inverted Z, and the base 417 of the plug busbar is securely connected to the base of the front metal piece of the plug. The upper part of the plug busbar has a projection in the shape of a plug piece 412, and the elastic pieces of the plug are generally V-shaped, comprising a retaining edge 414 and a bearing edge 411.The fixing edge 414 of the front metal part of the plug is located at the bottom of the plug busbar and is in close contact with the base 417 of the plug busbar. Preferably, the plug spring 413 is connected to one end of the plug connector 42 by a curved surface or an elastic arc portion, etc. The upper part of the plug spring 413 has a plug groove 418, which is located on each side of the plug spring 413, to facilitate the placement of the disconnecting device 3.

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

[0132] In this implementation example, the connector 42 may, but is not limited to, have a trapezoidal plate structure to establish the connection between the collector bundle and the spindle head, where this connector 42 may be integrally formed with the collector bundle. The connector 82 may also have a trapezoidal plate structure to connect the metal plate 815 of the rear connection element to the spindle sleeve 83.

[0133] In the aforementioned 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, strengthening the insertion and removal force of the connector.

[0134] In the aforementioned implementation example, the pin sleeve 83 has an expandable slot 833 extending through the tube wall. To facilitate expansion during the insertion and removal of the pin head 42, the pin sleeve 83 also has an expandable slot 832 that does not completely extend through the sleeve wall, thus making the pin sleeve 83 more elastic. Furthermore, the pin sleeve 83 can be hollow in structure, without limitation.

[0135] In the aforementioned implementation example, the spindle head 42 can be cylindrical without limitation. The upper part of the spindle head 42 has a telescopic joint 431, the width of which gradually narrows towards the spindle bore, thus imparting elasticity to the spindle head 42. This ensures flexibility and elasticity during the interconnection, minimizing the risk of deformation during installation. Of course, the spindle head 42 and the spindle sleeve 83 can also be designed without cracks or cutouts, while still maintaining a certain degree of elasticity.

[0136] In Figures 18 to 21, the first connection terminal 200 and the second terminal of Connection 300 also includes a disconnect device, comprising the first disconnect device 3 and the second disconnect device 3'. One end of the first disconnect device 3 extends into the first housing to compress the connector's clamping spring in order to open or close the first clamping port; the other end of the first disconnect device 3 extends out of the first housing. One end of the second disconnect device 3' extends into the second housing to compress the connector's clamping spring in order to open or close the second clamping port; the other end of the second disconnect device 3' extends out of the second housing. The first disconnect device 3 and the second disconnect device 3' have the same structure.

[0137] In the aforementioned implementation example, the first disconnection device comprises the first connecting arm 31 and two opposing support arms 32 connected to the first connecting arm 31. One end of the support arms 32 is connected to the connecting arm 31, while the other end of the support arms 32 is free and enters the outer housing of the first connecting terminal 2 to compress the connector's clamping spring. The end of the connecting arm 31 has anti-slip grooves to facilitate pivoting or lifting the first disconnection device during manual operation. Ideally, the front sides of the end of the connecting arm 31 can be clamped inwards.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 comes into contact with the edges of the flanks of the first plate 221 on each side.

[0138] When the retaining interface of the retaining device 4 is in the closed position, the first connecting arm 31 of the stripping device is either horizontal or nearly horizontal. Activating the first connecting arm 31 causes the first support 34 to contact the groove 418 of the elastic plate 413, while the second support 35 makes contact with the edges of the flanks of the first plate 221. As the disconnection prevention device rotates, the first support 34 progressively compresses the elastic plate, thus further opening the retaining 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 disconnecting device 3' comprises the second connecting arm 31' and two second support arms 32' arranged in opposition and connected to the second connecting arm 31'. OneOne end of the second support arm 32' is connected to the second connecting arm 31', and the other end of the second support arm 32' is a free end that extends into the external housing of the second connecting terminal 2' to compress the connector's clamping spring. The end of the second connecting arm 31' is equipped with anti-slip grooves to facilitate rotation or manual lifting of the disconnect device 3' during manual operation. Ideally, the front sides of the end of the second connecting arm 31' can also be clamped inward. The bottom of the support wall is triangular, with a third triangular support projecting inside the support wall, and a fourth support 35' located on the top of the third support 34'.The third support 34' cooperates with the groove 818 of the elastic plate 813 of the connector, and the fourth support 35' comes into contact with the edges of the flanks of the second plate 221' on each side.

[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' comes into contact with the tab of the connector 813 in the tab's recess, and the fourth support 35' comes into contact with 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 connector's recess.

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

[0142] As illustrated in Figures 22 to 25, in this embodiment the plug-in connector also includes a cable protection box 400, comprising an upper cover 5 and a lower base 6, the upper cover 5 being hinged on 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 mounted respectively 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 Positioning space 410 contains a plug-in slot 420 for the first connection terminal 200 or the second connection terminal 300 for a plug-in or insertable connection. Additionally, a through hole 430 is located at the rear of positioning space 410 to allow cables to pass externally.

[0144] In the example above, the pressure cover of connector 1 also includes an insertion cap locking slot 15 located at the end of the connector socket, and the pressure cover of receptacle 7 also includes an insertion cap locking slot 75 located at the end of the receptacle. The upper cover 5 includes an upper cover wall 52 and two upper cover side walls 53 connected to the upper cover wall 52. The front segment of the upper cover side walls 53 has an upper cover groove 531 for seating the first connection terminal 200 / second connection terminal 300, and the front of the upper groove of cover 531 has an upper cover locking interface 55 complementary to the insertion cap locking slot 15 or 75 of the connector or receptacle.The inside of the upper cover wall 52 has projecting tabs 56 connected to the two upper cover side walls 53, the projecting tabs 56 serving to position the first connection terminal 200 or the second connection terminal 300.

[0145] In the example above, the rear of the upper cover wall 52 is equipped with an insertion hole 521, and a cable clamp 54 is fixed to the rear 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 rear of the insertion hole 521 of the upper cover wall, and the lever segment 542 extends into the upper groove of the cover 531 to elastically adapt to the conductor wire through the hole 430. It is understood that the lever segment 542 is elastic, which allows it to automatically clamp wires of different sizes thanks to its own elasticity.

[0146] In the example above, the lever segment 542 is bent into a hook shape. More specifically, the lever segment 542 bends backward and curves toward the direction of insertion of the conductor wire to make contact with the conductor wire. The bending design of the lever arm segment can strengthen the force of the cable clamp 54 and, at the same time, ensure a more stable fastening 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 equipped with mounting arms 61 compatible with the rotation axis 51. More specifically, the rotation axis 51 is connected to the hooks of the mounting arms. When the upper cover 5 When the top cover 5 is open, the 200 or 300 connection terminals can be installed in the junction box 400; when the top cover 5 is closed, the 200 or 300 connection terminals are locked inside the junction box 400. Ideally, the end of the rotating shaft 51 can be fitted with a letter-shaped locking pin, facilitating the installation of the 200 or 300 connection terminals when the junction box 400 is open. When the top cover 5 is closed, the junction box 400 ensures the stability and safety of the 200 or 300 connection terminals.

[0148] In this example implementation, the lower base 6 comprises a bottom base 62 and two side panels 63 connected to this base. The front end of the side panels 63 has a groove 631 for the placement of the first connection terminals 200 and the second connection terminals 300. The center of the bottom base 62 is equipped with a connection port 621, which has a spring-loaded locking device 66. When the first or second connection terminals 200 / 300 are inserted into the groove 631, the locking device 66 holds these terminals in place to prevent any movement.

[0149] In this embodiment, the cable protection box 400 includes a locking component, which includes a fastening piece 67 located at the rear of the lower base 6. The fastening piece 67 has the structure of a longitudinal strip-shaped plate extending upwards from the base of the lower base 62 along the side wall of the base 63. The end of the fastening 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 locking mechanism with the latter. It is understandable that the locking component can make the use of the cable protection box safer.

[0150] The fixing piece 67 is connected to the base of the lower plinth 62, at which point there are two crossbars which pass through said base of the plinth 62. When the cover and the plinth 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 anti-slip patterns 65. The anti-slip patterns 65 can play an anti-slip role during assembly and use.

[0152] In a preferred embodiment, embodiment example 1 describes that the connection terminals can be connected in parallel in several, thus forming a series of multiple connection terminals. Example of execution 2

[0153] This embodiment example uses the same components, connection modes and structural descriptions as embodiment example 1, so they are not described again.

[0154] As illustrated in Figures 29 to 30, this example of implementation improves the connector stripping device 3. This stripping device 3 includes a connecting arm 31, as well as two parallel support arms 32 that are linked to the connecting arm 31, and a connecting arm 37 that is also attached to the connecting arm 31 and is located between the support walls 32. The support arms 32 and the connecting arm 37 form two placement zones 33. It is understandable that in this example of embodiment, the extraction device 3 is designed as a single-piece structure, which means that a single extraction device 3 can simultaneously open or close several insertion connector clamping devices and / or adapter clamping devices, thus simplifying operations. Example of execution 3

[0155] This embodiment example uses the same components, connection modes and structural descriptions as embodiment example 1, so they are not described again.

[0156] As shown in Figures 31 to 40, this example improves the protective housing 400. A positioning space 410 is formed between the lower base 6 and the upper cover 5, allowing the positioning of at least two first connection terminals 200 or at least two second connection terminals 300. At the front of this positioning space 410, at least two slots 420 are provided to allow access to the connections of the first or second connection terminals 200 / 300. In addition, at the rear of the positioning space 410, at least two openings 430 are provided for the passage of wires to the outside. More specifically, the first connection terminals 200 and the second connection terminals 300 are installed respectively in two cable protection boxes, for use in different locations.This example implementation allows for the parallel connection of an insertion connector from example implementation 1 with the insertion connector of this example, thus forming a set of multiple connection terminals.

And / or the side wall of the lower base 63 is provided with at least one reinforcing rib 632. The reinforcing ribs can strengthen the side walls of the upper cover 5 and the lower base 6, thus reducing the deformation of the cable protection box during its use.

[0158] In this embodiment, the upper cover 5 and the lower base 6 can also be connected by screws. More specifically, the end of the cover wall 52 has screw holes 58, and corresponding screw holes 68 are located on the base of the plinth 62, thus reinforcing the cable protection box using screws.
