Description

Technical Field

[0001] The invention relates to the technical field of sockets, and in particular to an improved structure of a heavy-duty connector for quick wiring. Background Art

[0002] Heavy-duty connectors, also known as HDC heavy-duty connectors and aviation connectors, can work under harsh environmental conditions such as high temperature, high humidity, strong corrosive media and vibration. They are widely used in construction machinery, textile machinery, packaging and printing machinery, tobacco machinery, robots, rail transportation, hot runners, electric power, automation and other equipment that require electrical and signal connections, and they play an important role in connecting the upper and lower levels.

[0003] Heavy-duty connectors are mainly composed of modules such as inserts, pins, shells (including frames, upper shells and bases), and accessories. The insert is a key component in heavy-duty connectors and usually forms an electrical module together with the pins. The design and structure of the insert are critical to ensuring a good electrical connection. When the plug is inserted into the socket, the pins on the plug will contact the contact points of the insert on the socket to form a physical connection. Fig.19 As shown, the socket is installed on the side of the control cabinet, the outer side is used to connect with the plug, and the inner side extends into the control cabinet; the socket is installed in front of the control cabinet, and the multiple plugs on the socket must be fixedly connected with cables, and then the cables are pulled into the control cabinet and electrically connected to the corresponding wiring terminals in the control cabinet. A large number of cables need to be laid to extend and connect to the wiring terminals. In addition, due to the large amount of wiring in the wiring terminals in the control cabinet, the wiring terminals are often connected incorrectly, and inspection and correction are extremely cumbersome. Therefore, developing a method to reduce the amount of cables and improve the simplicity and accuracy of wiring of the wiring terminals is a technical problem that needs to be solved in this case. Summary of the invention

[0004] In view of the above problems, the present invention provides a heavy-duty connector for quick wiring, which has a sophisticated structure, reduces the amount of cables used, and improves the wiring accuracy of wiring terminals.

[0005] The technical solution of the present invention is: A heavy-duty connector for quick wiring, comprising: A heavy-duty connector for quick wiring, comprising: The socket has a plurality of jacks on the front side, and the jacks are provided with detachable and fixed plug cores; A plurality of wiring insulating seats are provided, which are detachably fixed on the rear side of the socket; a pair of wiring cavities are provided in the wiring insulating seat; an upper cavity is provided in the wiring cavity, and a second terminal is provided inside the upper cavity. The second terminal is electrically connected to the first wire through a connecting piece, and the first wire is electrically connected to the ferrule; the second terminal is electrically connected to the components in the cabinet through the second wire.

[0006] Specifically, a first terminal is provided between the first wire and the connecting piece; A lower cavity adapted to the first terminal post is provided in the wiring insulation seat, and the lower cavity is communicated with the upper cavity.

[0007] Specifically, the lower cavity is disposed transversely, and the first terminal is disposed transversely in the lower cavity; A first through hole for adjusting a first terminal post clamping bolt is provided on a side of the terminal insulation seat.

[0008] Specifically, the cross section of the connecting piece is L-shaped.

[0009] Specifically, the lower cavity is vertically arranged and located at the side of the upper cavity; the first terminal is vertically arranged in the lower cavity; The top of the wiring insulation seat is provided with a second through hole for adjusting the first wiring post clamping bolt.

[0010] Specifically, the cross section of the connecting piece is in a Z-shaped or straight-line structure.

[0011] Specifically, a third through hole for adjusting a clamping bolt of the second terminal post is provided on the top of the terminal insulation seat.

[0012] Specifically, a pair of slide grooves are provided on the rear side of the socket; The wiring insulation seat is provided with a pair of positioning parts adapted to the slide slots, and the positioning parts can be detachably clamped on the pair of slide slots.

[0013] Specifically, the positioning portion is a hook portion, and the top surface of the hook portion is a plane that is inserted into the slide groove.

[0014] Specifically, the positioning portion is an arc-shaped protrusion, and the arc-shaped protrusion is inserted into the sliding groove.

[0015] Specifically, the cross section of the socket is a rectangular structure or an L-shaped structure.

[0016] The present invention comprises a socket and a wiring insulating seat. The wiring insulating seat is improved in structure to form a pair of wiring cavities. The upper cavity in the wiring cavity is provided with a second terminal. The second terminal is electrically connected to the first wire through a connecting piece. The first wire is electrically connected to the plug core. This not only simplifies the wiring method, but also shortens the length of the connecting line from the jack to the wiring insulating seat to 1 / 10 of the original length, thereby saving wire materials and reducing manufacturing and installation costs.

[0017] The single-piece wiring insulation seat adopts a pair of second terminal settings, which not only improves the compactness and rationality of the structure, but also reduces the occupied area, increases the wiring and line checking space, and simplifies and facilitates on-site operations. The wiring insulation seat has the same serial number as the connected aviation socket jack, which can reduce the wiring error rate and shorten the construction wiring and fault checking time.

[0018] The design improvement of the connection method of sockets and wiring insulation seats makes maintenance and replacement easier and easier to standardize, which improves the production efficiency and process consistency of the secondary wiring of distribution network complete switchgear, reduces the workload of on-site construction, commissioning, operation and maintenance, and improves the safety, reliability and economy of electrical operation.
