Description

Technical Field

[0001] This application relates to the field of connectors, and more particularly to a tee cable connector. Background Technology

[0002] Connectors, also known as plugs or connectors, are used to connect two active devices to transmit current or signals. Mining cable connectors, as information and communication cable connectors, are used to transmit current and are mainly used in underground coal mines and environments with mixtures of explosive gases such as coal dust and methane.

[0003] Commonly used cable connectors only support conventional cable connections, but conventional cables have limited transmission capacity. Some mining equipment requires simultaneous transmission of large amounts of electrical energy. To meet practical needs, related technologies use junction boxes to branch cables. However, in actual use, mining equipment requires regular maintenance, repair, or component replacement, necessitating the disconnection and reconnection of cable connectors. This necessitates multiple manual wire disconnections and reconnections at the junction box, which is cumbersome, unsafe, and unsuitable for high-current branching.

[0004] To address the aforementioned problems, the inventors designed a three-way cable connector. This cable connector includes a socket module, a plug module, an adjustable module, and a connecting module. The socket module, plug module, and adjustable module are all used for electrical connection with the cable. The connecting module distributes the current from the plug module to the socket module and the adjustable module. The socket module, plug module, and adjustable module all plug into and are electrically connected to the connecting module. This allows users to easily plug and unplug the cable connector multiple times during use, and also ensures high operational safety. The connecting module includes a base, a cover, and a housing mounted on the outside of the base and cover. The structure for electrical connection with the socket module, plug module, and adjustable module is located on the base and cover. The inventors discovered that during the assembly of the cable connector, because the structure for electrical connection needs to be installed into the base first, and the base and cover are then closed, and the housing is used to press and fix the base and cover together, the base and cover are prone to loosening and shifting during assembly and transfer. This causes the internal structure for electrical connection to fall out, requiring rework and adjustment when installing the housing, thus affecting assembly efficiency. Utility Model Content

[0005] To address the technical problem of reduced assembly efficiency due to rework adjustments required during housing installation, this application provides a three-way cable connector.

[0006] This application provides a three-way cable connector, which adopts the following technical solution:

[0007] A three-way cable connector includes a socket module, a plug module, an adjustable module, and a connecting module. The socket module, plug module, and adjustable module are all used for electrical connection with a cable. The connecting module is used to distribute the current on the plug module to the socket module and the adjustable module. The socket module, plug module, and adjustable module are all plugged into the connecting module. The connecting module includes a base and a cover. The base and cover are provided with a fixing structure and are fixedly connected by the fixing structure.

[0008] By adopting the above technical solution, the base and the cover are set independently, which facilitates the assembly of the electrical connection structure. The base and the cover are fixedly connected by a fixed structure, without the need for fixation by an external shell. The base and the cover will not loosen or shift during the assembly process, and the requirements for the placement angle of the parts are low, which facilitates assembly.

[0009] Optionally, the fixing structure includes an injection hole on the base and an insert on the cover for inserting into the injection hole.

[0010] By adopting the above technical solution, during assembly, glue is filled into the glue injection hole, and then the cover is closed. The insert on the cover is inserted into the glue injection hole, causing the glue in the glue injection hole to overflow onto the side wall opposite to the base of the cover, resulting in a firm bond and good connection stability.

[0011] Optionally, the socket module, plug module, and adjustable module all include a power connection component. The connection component is provided in multiple sets, and the multiple sets of connection components are electrically connected to the power connection component. Adjacent connection components are electrically connected by connectors, and the cover is used to fix the connectors to the base.

[0012] By adopting the above technical solution, the connection module, socket module, plug module, and adjustable module are electrically connected through the connection component and the power connection component. Furthermore, multiple sets of connection components are electrically connected through the connector, which enables the current on the plug module to be distributed to the socket module and the adjustable module, facilitating assembly and ensuring stable electrical transmission.

[0013] Optionally, the base is provided with a mounting groove for accommodating the connector, and the cover is provided with a pressure plate for inserting into the mounting groove.

[0014] By adopting the above technical solution, the space for the connector is reduced by inserting the pressure plate into the mounting groove, which helps to prevent the connector from moving in the mounting groove and improves the stability of the electrical connection.

[0015] Optionally, the socket module, plug module, and adjustable module all include a housing, the power connection component is disposed inside the housing, the housing has a plug slot, the base and the cover both include a plug part, the connecting component is disposed on the plug part, and the plug part and the plug slot are plugged into each other.

[0016] By adopting the above technical solution, the plug-in part is inserted into the slot on the housing to realize the positioning connection of the connection module, socket module, plug module and adjustable module, which facilitates assembly and realizes electrical connection, and the assembly safety is good.

[0017] Optionally, the connection module further includes a housing, which includes a first housing and a second housing. Both the first housing and the second housing have receiving grooves. The receiving groove on the first housing is used to receive the insertion part of the base, and the receiving groove on the second housing is used to receive the insertion part of the cover. The first housing and the second housing, as well as the housing and the outer shell, are detachably connected.

[0018] By adopting the above technical solution, the housing serves to protect the cover and the base, and the two housings and the housing and the outer shell are detachably connected, which facilitates assembly and also makes it easy to disassemble when repairing or replacing the cable connector.

[0019] Optionally, it also includes a locking member for fixing the first housing and the second housing. The first housing and the second housing are provided with flanges on their opposite sidewalls. The flanges are provided with fixing holes extending along the arrangement direction of the first housing and the second housing, and the fixing holes are for the locking member to pass through.

[0020] By adopting the above technical solution, the housing is connected by flanges, which can fix the socket module, plug module and adjustable module, ensuring the normal and stable use of the cable connector. The flange connection structure has high strength, which can meet the needs of mining. Moreover, the flange process is mature, easy to produce and the production cost is controllable. The locking part passes through the fixing hole to fix the two flanges. There is no need to make too many structural modifications to the flanges, which is convenient for processing.

[0021] Optionally, the locking element includes a locking rod, which includes a limiting part and a blocking part disposed at both ends. The limiting part and the blocking part are respectively located on opposite sides of the two flanges. The cross-sectional dimension of the limiting part is larger than the cross-sectional dimension of the fixing hole. A locking groove is formed on the outer peripheral surface of the blocking part, extending in a direction perpendicular to the arrangement direction of the first housing and the second housing. A locking block is slidably disposed in the locking groove. An elastic element for ejecting the locking block from the locking groove is connected between the locking block and the bottom wall of the locking groove.

[0022] By adopting the above technical solution, after the two flanges are fitted together, the locking block on the locking rod is pressed back into the locking groove, and then the locking rod is inserted into the fixing hole until the locking rod passes through the two fixing holes. The locking block pops out of the locking groove under the elastic force of the elastic element, and the locking block and the limiting part abut against the two flanges respectively, thus fixing the two flanges. Compared with the connection by bolts, the locking rod fixing operation is more convenient.

[0023] Optionally, a guide slope is formed on the end of the lock block away from the bottom wall of the lock groove, and the distance between the guide slope and the bottom wall of the lock groove decreases along the direction in which the locking rod is inserted into the fixing hole.

[0024] By adopting the above technical solution, when installing the locking rod, you only need to insert the locking rod into the fixing hole. There is no need to manually press the locking block back into the locking groove. The edge of the fixing hole opening abuts against the guide slope, and the locking block will be automatically pressed back into the locking groove, which further improves the ease of installation.

The two flanges 434 are fixed with bolts, thereby fixing the socket module 1, the plug module 2, the adjustable module 3, and the connecting module 4 together.

[0055] Example 2:

[0056] Reference Figure 7 and Figure 8 Unlike Embodiment 1, this embodiment includes a locking member 7 for fixing the first housing 431 and the second housing 432 within the fixing hole 435. The locking member 7 includes a locking rod 71, which comprises a limiting part 711 and a blocking part 712 located at both ends. After the locking rod 71 is installed, the limiting part 711 and the blocking part 712 are located on opposite sides of the two flanges 434. The cross-sectional dimension of the limiting part 711 is larger than the cross-sectional dimension of the fixing hole 435.

[0057] Reference Figure 8 and Figure 9 A locking groove 713 extending in a direction perpendicular to the axial direction of the fixing hole 435 is formed on the outer peripheral surface of the blocking part 712. The locking groove 713 includes a large-diameter section 714 and a small-diameter section 715 communicating with the large-diameter section 714. The small-diameter section 715 is located on the side of the large-diameter section 714 away from the bottom wall of the locking groove 713 and communicates with the outside. A locking block 8 is slidably installed in the large-diameter section 714 and the small-diameter section 715. An elastic member 9 is press-fitted between the locking block 8 and the bottom wall of the large-diameter section 714. The elastic member 9 extends and retracts in the direction that ejects the locking block 8 from the locking groove 713. A limiting boss 82 is integrally formed on the locking block 8. The limiting boss 82 slides in the large-diameter section 714. The cross-sectional dimension of the limiting boss 82 is larger than the cross-sectional dimension of the small-diameter section 715 to prevent the locking block 8 from falling out of the locking groove 713.

[0058] Reference Figure 7 and Figure 9 A guide slope 81 is formed on the end of the locking block 8 away from the bottom wall of the large diameter section 714. The distance between the guide slope 81 and the bottom wall of the large diameter section 714 decreases along the direction in which the locking rod 71 is inserted into the fixing hole 435.

[0059] The assembly principle of a three-way cable connector in Embodiment 2 of this application is as follows: After the two flanges 434 are in contact and fit together, a locking rod 71 is inserted into the fixing hole 435, the guide slope 81 abuts against the edge of the opening of the fixing hole 435, and the locking block 8 is pressed back into the locking groove 713 until the locking rod 71 passes through the fixing hole 435 on the second flange 434. Under the elastic force of the elastic member 9, the locking block 8 pops out of the locking groove 713, and the locking block 8 and the limiting part 711 abut against the two flanges 434 respectively, thus fixing the two flanges 434.

[0060] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application.
