Description

Technical field

[0001] The present utility model relates to terminal blocks, in particular a wall feed-through terminal block for cable-to-cable connection. State of the art

[0002] A cable-to-cable terminal block is used to create an electrical connection between individual wire terminals. This type of connection can be used in panel mounting, in addition to cable-to-cable coupling, where a terminal block must be attached to the panel, which is usually only possible with the aid of a panel bracket. Despite its widespread use, the panel-side terminal block is prone to detachment and costly to replace when fitted with the other terminal block.

[0003] When using a conventional terminal block for cable-to-cable connections in a panel, a mounting bracket is required. First, the bracket must be mounted and secured to the panel, and then the terminal block is inserted into the bracket to enable its use on the panel. In practical applications, because the terminal block is attached to the bracket via an elastic locking mechanism, there is a very high risk that, during the connection of the plug and terminal block to the panel, the terminal block will detach from the bracket due to insufficient locking force. Content of the invention

[0006] In a further preferred technical solution according to the present utility model, it is proposed that the through hole is designed as a connecting hole in a convex shape, and that a rib is provided on the inside sides of the two clamping grooves of the mounting frame, with the two ribs each being located on the upper projecting part of the convex shape.

[0007] Preferably, the clamping slots are accessible from outside the panel and they interact with a plug with a locking function.

[0008] Preferably, the rectangular nuts are fastened by snapping them into the outer flanges.

[0009] Advantageous effects: (1) The socket of the terminal block according to the utility model uses a two-flange design. The inner flanges serve to secure the connector. Rectangular nuts are provided in the interiors of the outer flanges. The outer flanges are fastened to the terminal block socket on the connecting panel by screws. The rectangular nuts in the outer flanges are secured by a snap-fit ​​mechanism, enabling simple and reliable assembly. The design of the rectangular nuts in the outer flanges facilitates on-site assembly and fastening of the terminal block socket.The utility model optimizes the structure of the terminal block socket in the prior art and can be compatible with more types of plugs than with the conventional terminal block, thus improving the solution for wall penetration of the terminal block socket and making the product more competent.

[0010] (2) In the utility model, the socket of the terminal block is directly attached to the connecting panel by the screws, thus integrating the fastening function of a panel bracket from the prior art into the utility model and attaching the socket of the terminal block directly to the connecting panel. This simplifies the solution for the wall penetration of the socket of the terminal block. The utility model improves the reliability of the product in use and avoids the risk of detachment, as can occur with the socket of a conventional terminal block. Furthermore, this design eliminates the need for a panel bracket, which not only reduces costs but also increases the efficiency of installation.

[0011] (3) The design according to the utility model is compatible with the socket of the conventional terminal block and the openings of the connecting panel in the solution with a holder for the panel, and can directly replace them.
