[0001] This application relates to the field of connectors, and in particular to a multi-pass cable connector. Background Art

[0002] A connection module, also known as a connector, is used to connect two active devices and transmit current or signals. The mine cable connection module, as an information communication cable connection module, is used to transmit current and is mainly used in coal mines and environments with explosive gas mixtures such as coal dust and methane around.

[0003] Common cable connection modules only support conventional cable connections, and the transmission function of conventional cables is limited. Some mine equipment requires simultaneous transmission of more electrical energy. To meet the actual usage requirements, in related technologies, a junction box is set up to tap the cable. However, in the actual usage process, since mine equipment needs to be regularly maintained, repaired, or parts replaced, the cable connection module needs to be disconnected and reconnected, then multiple manual wiring disconnections of the cable tap wires need to be carried out in the junction box, which is troublesome to operate and has low safety, and is not suitable for large current tapping. Summary of the Invention

[0004] In order to facilitate operation and improve operation safety, this application provides a multi-pass cable connector.

[0005] A multi-pass cable connector provided by this application adopts the following technical solutions:

[0006] A multi-pass cable connector includes a socket module, a plug module, an adjustable module, and a connection module. The socket module, the plug module, and the adjustable module are all used for electrically connecting to a cable, and the socket module, the plug module, and the adjustable module are all plugged and cooperated with the connection module and electrically connected.

[0007] By adopting the above technical solutions, by setting the connection module and the adjustable module, cable tapping is realized, which is suitable for large current tapping. When in use, the user only needs to realize the plugging and cooperation of the socket module, the plug module, and the adjustable module with the connection module, without the need for manual wiring tapping, which is convenient to operate and improves operation safety.

[0008] Optionally, the socket module, the plug module, and the adjustable module all include a plugging component. The plugging component includes a male plug. The connection module includes a connecting piece and multiple groups of female plugs. The multiple groups of female plugs are plugged and cooperated with the male plugs in the socket module, the plug module, and the adjustable module, and the connecting piece is electrically connected to adjacent two groups of female plugs.

The connecting piece is arranged in the installation groove. A pressing plate for inserting into the installation groove is arranged on the cover body.

[0011] By adopting the above technical solution, the accommodation space of the connecting piece is reduced by inserting the pressing plate into the installation groove, and the movement of the connecting piece in the installation groove is prevented as much as possible, so as to improve the electrical connection stability.

[0012] Optionally, the socket module, the plug module and the adjustable module all include a housing. A slot is formed on the housing. The base includes a plurality of plug-in parts. Each of the female sockets is arranged on the plug-in part, and each of the female sockets corresponds to the plug-in part. The plug-in part is in plug-in fit with the slots on the housings of the socket module and the adjustable module. The cover body includes an insertion part. A through hole for the female socket to pass through is formed on the insertion part. The insertion part is in plug-in fit with the slot on the housing of the plug module.

[0013] By adopting the above technical solution, the plug-in part is in plug-in fit with the slot on the housing to guide the movement of the connection module and the socket module, the plug module and the adjustable module, so as to realize the positioning connection of the connection module and the socket module, the plug module and the adjustable module, which is more convenient for assembly. The base allows a group of female sockets to pass through, which can realize the relative positioning of the base and the cover body and is applicable to the three-way scenario.

[0014] Optionally, a pin shaft is arranged on the housing. A positioning groove extending along the direction in which the plug-in part is inserted into the slot is formed on the plug-in part. The positioning groove is used for the pin shaft to insert and move.

[0015] By adopting the above technical solution, the cooperation of the positioning groove and the pin shaft can not only guide the insertion of the plug-in part into the slot, but also prevent the relative rotation of the two after the connection module and the housing are inserted in place, and has good connection stability.

[0016] Optionally, it further includes two connecting flanges. At least one connecting housing is arranged on each connecting flange. The connecting housing is used for accommodating the connection module. The socket module, the plug module and the adjustable module are all independently connected to a connecting housing.

[0017] By adopting the above technical solution, the connection module is accommodated in the connection housing, which plays a protective role for the connection module. Moreover, the connection housing is connected by a flange, which can fix the socket module, the plug module and the adjustable module, ensuring the normal and stable use of the cable connector. The flange connection has high structural strength, can meet the mining requirements, and the flange plate has a mature process, convenient production and controllable production cost.

[0018] Optionally, the socket module, the plug module and the adjustable module all include a housing. Slots are formed in the housing. The base includes two insertion parts. Installation holes communicating with the installation groove are formed in the insertion parts. The plugging female heads provided on the connection module are in two groups, and the two groups of plugging female heads are respectively arranged in the installation holes of the two insertion parts. The cover body includes a first cover body and a second cover body. The pressing plate is arranged on the first cover body. The first cover body is used to close the installation groove, and the second cover body is used to close the installation hole. A fixing structure is further included. The first cover body is fixedly connected to the insertion part or the second cover body through the fixing structure.

[0019] By adopting the above technical solution, the cover body is divided into a first cover body and a second cover body. The two insertion parts are respectively inserted and matched with the slots on the housings of the socket module and the adjustable module, or the plug module and the adjustable module, or the two adjustable modules. That is, one insertion part on one base is used to connect with one insertion part on another base. Then, the insertion parts for connecting the two bases can respectively insert into one housing, and one insertion part on both bases can be left vacant for inserting into the remaining housings on the basis of electrical connection, and so on. Different numbers of bases can be selected according to different usage requirements. Then, the base is closed by fixedly connecting the first cover body and the second cover body or the first cover body and the insertion part. When producing the cable connector, only one specification of the base and two specifications of the cover body need to be produced. Different numbers of bases are connected and combined with different numbers of cover bodies to meet different requirements, instead of customizing different bases for different requirements, improving the shipping efficiency and reducing the inventory backlog.

[0020] Optionally, both the insertion part and the second cover body are cylindrical. Arc-shaped grooves for inserting the insertion part and the second cover body respectively are formed on the first cover body. Lock grooves are formed on the groove walls of the arc-shaped grooves. The fixing structure includes a lock block slidably arranged in the lock groove and a fixing groove for inserting the lock block. The fixing groove is formed on the outer peripheral surfaces of the insertion part and the second cover body. An elastic member for driving the lock block to move out of the lock groove is arranged between the lock block and the bottom wall of the lock groove.

[0021] By adopting the above technical solution, an arc-shaped groove is formed on the first cover body for the insertion part and the second cover body to be inserted, which can limit the relative movement of the first cover body and the second cover body or the first cover body and the insertion part in two degrees of freedom. Then, in cooperation with the fixing structure, the first cover body and the second cover body or the first cover body and the insertion part are fixedly connected. When the lock block pops out of the lock groove under the elastic force of the elastic member and inserts into the fixing groove, the fixed connection between the first cover body and the insertion part or the first cover body and the second cover body can be realized, which is convenient for operation and has good connection stability.

[0022] Optionally, the fixing structure further includes two sliders provided on the groove wall of the arc-shaped groove and sliding grooves opened on the second cover body and the insertion part. The lock groove extends along the arrangement direction of the first cover body and the second cover body, and the lock groove is located between the two sliders. The sliders are slidably arranged in the sliding grooves. One groove wall of the sliding groove is a locking inclined surface, and the locking inclined surface is inclined and used to contact the slider. When the slider is completely inserted into the sliding groove, the locking inclined surface is located on the side of the adjacent slider close to the lock groove, and the distance between the locking inclined surface and the slider decreases along the direction in which the slider is inserted into the sliding groove. An elastic seal is provided on the groove wall of the sliding groove opposite to the locking inclined surface.

[0023] By adopting the above technical solution, when fixing the first cover body and the second cover body or the first cover body and the insertion part, the first cover body moves, so that the slider slides in the sliding groove, and the locking inclined surface contacts the slider, thereby driving the first cover body to move towards the direction close to the second cover body or the insertion part. After the lock block is inserted into the fixing groove, under the extrusion of the locking inclined surface, the slider extrudes the elastic seal. Even if there is a gap between the lock block and the fixing groove, resulting in relative movement between the first cover body and the second cover body or the insertion part, the elastic seal is still in the extruded state, playing a good sealing effect.

[0024] Optionally, an extension block is provided on the slider, and a rotation prevention groove for the extension block to be inserted is opened on the base.

[0025] By adopting the above technical solution, through the insertion and cooperation of the extension block and the rotation prevention groove, the relative rotation of the first cover body and the base is prevented, thereby preventing the relative rotation of the two bases.

[0026] In summary, the present application includes at least one of the following beneficial technical effects:

[0027] 1. Suitable for large current tap-changing, without the need for multiple manual wiring operations, convenient for operation, and improving operation safety;

[0028] 2. By pressing the connecting member with the pressing plate, the movement of the connecting member in the installation groove is prevented, and the electrical connection stability is improved;

[0029] 3. When producing the cable connector, only one specification of the base and two specifications of the covers need to be produced. Different numbers of bases are connected and then combined with different numbers of covers to meet different requirements, instead of customizing different bases for different needs, which improves the shipping efficiency and reduces inventory backlog.

Arc-shaped grooves 446 are formed at both ends in the length direction of the first cover body 444. The arc-shaped grooves 446 are semi-circular grooves, and the arc-shaped grooves 446 penetrate through the first cover body 444 along the arrangement direction of the cover body 44 and the base 43. The arc-shaped grooves 446 are used to accommodate half of the outer circumferential surface of the second cover body 445 or the insertion part 432, so as to limit the movement of the second cover body 445 or the insertion part 432 relative to the first cover body 444 in the direction perpendicular to the arrangement direction of the cover body 44 and the base 43 and the arrangement direction of the first cover body 444 and the second cover body 445.

[0059] Referring to Figure 7 and Figure 8 , fixing structures 6 are provided on both the first cover body 444, the second cover body 445 and the insertion part 432. The fixing structures 6 are used to fixedly connect the first cover body 444 and the second cover body 445 or the first cover body 444 and the insertion part 432.

[0060] Referring to Figure 8 and Figure 9, a locking groove 447 is formed on the bottom wall of the arc-shaped groove 446. The locking groove 447 extends along the length direction of the first cover body 444. The locking groove 447 includes a large-diameter section 448 and a small-diameter section 449 communicating with the large-diameter section 448. The small-diameter section 449 is located on the side of the large-diameter section 448 away from the bottom wall of the locking groove 447, and the small-diameter section 449 communicates with the outside. The fixing structure 6 includes a locking block 61 slidably installed in the large-diameter section 448 and the small-diameter section 449. An elastic member 63 is press-fitted between the locking block 61 and the bottom wall of the locking groove 447. The elastic member 63 expands and contracts along the direction of ejecting the locking block 61 out of the locking groove 447.

[0061] Refer to Figure 7 and Figure 9 , a limiting boss 611 is integrally formed on the locking block 61. The limiting boss 611 slides in the large-diameter section 448. The cross-sectional dimension of the limiting boss 611 is larger than the cross-sectional dimension of the small-diameter section 449 to prevent the locking block 61 from disengaging from the locking groove 447. A guiding inclined surface 612 is formed at the end of the locking block 61 away from the bottom wall of the locking groove 447. The distance between the guiding inclined surface 612 and the bottom wall of the locking groove 447 gradually increases along the arrangement direction of the cover body 44 and the base 43.

[0062] Refer to Figure 8 and Figure 10 and Figure 11 , the fixing structure 6 further includes a fixing groove 62 formed on the outer peripheral surfaces of the second cover body 445 and the insertion portion 432. The fixing groove 62 is for the locking block 61 to insert into, so as to limit the movement of the second cover body 445 or the insertion portion 432 relative to the first cover body 444 in the arrangement direction of the cover body 44 and the base 43.

[0063] Refer to Figure 8 and Figure 9 , the fixing structure 6 further includes a slider 64 integrally formed on the groove wall of the arc-shaped groove 446 near the groove opening. There are two sliders 64 on each arc-shaped groove 446, and the two sliders 64 are respectively located on both sides of the locking groove 447.

[0064] Refer to Figure 8 and Figure 10 and Figure 11 , the fixing structure 6 further includes a sliding groove 65 formed on the second cover body 445 and the insertion portion 432. The slider 64 slides in the sliding groove 65. One of the groove walls of the sliding groove 65 is a locking inclined surface 651. The locking inclined surface 651 is inclined and used to abut against the slider 64. When the slider 64 is completely inserted into the sliding groove 65, the locking inclined surface 651 is located on the side of the adjacent slider 64 close to the locking groove 447. The inclined direction of the locking inclined surface 651 is opposite to the inclined direction of the guiding inclined surface 612. A locking inclined surface 651 is also formed on the side wall of the slider 64 for abutting against and sliding with the locking inclined surface 651 on the sliding groove 65. The locking inclined surface 651 is used to guide the first cover body 444 and the second cover body 445 or the insertion portion 432 to approach each other.

[0065] Refer to Figure 8 With Figure 10 And Figure 11 , on the groove wall of the sliding groove 65 opposite to the locking inclined surface 651, an elastic seal 7 is fixed. The elastic seal 7 can be made of elastic rubber material. The elastic seal 7 cooperates with the locking inclined surface 651. The locking inclined surface 651 guides the first cover body 444 and the second cover body 445 or the plug-in part 432 to approach each other, so that the slider 64 presses the elastic seal 7, achieving a good sealing and insulating effect.

[0066] Refer to Figure 8 With Figure 11 , an extension block 641 is integrally formed on the surface of the slider 64 close to the base 43. A rotation-preventing groove 434 for inserting the extension block 641 is formed on the base 43. The extension block 641 is in plug-in fit with the rotation-preventing groove 434 to prevent the two bases 43 from rotating relative to each other.

[0067] In this embodiment, by splitting the cover body 44 into the first cover body 444 and the second cover body 445, the two plug-in parts 432 are respectively in plug-in fit with the socket module 1 and the adjustable module 3, or the plug module 2 and the adjustable module 3, or the slots 121 on the housing 12 of the two adjustable modules 3. At this time, the arrangement angles of the two adjacent electrically connected bases 43 differ by 180°. That is, one plug-in part 432 on one base 43 is connected to one plug-in part 432 on the other base 43. Then, the plug-in parts 432 connecting the two bases 43 can respectively plug into one housing 12, and one plug-in part 432 of each of the two bases 43 can be left vacant for plugging into the remaining housings 12 on the basis of electrical connection. And so on. Different numbers of bases 43 can be selected according to different usage requirements, and then the bases 43 are enclosed by fixedly connecting the first cover body 444 and the second cover body 445 or the first cover body 444 and the plug-in part 432. When producing the cable connector, only one specification of the base 43 and two specifications of the cover body 44 need to be produced. Different numbers of bases 43 are connected and combined with different numbers of cover bodies 44 to meet different requirements, improving the shipping efficiency and reducing the inventory backlog.

[0068] The above are all the preferred embodiments of this application. The protection scope of this application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
