Two-part bracket for mounting folding transducers

Abstract

Two-part holder for accommodating several clamp-on current transformers (continuity testers), consisting of a holder (1) and a DIN rail holder (2), characterized in that the holder (1) is connected to the DIN rail holder (2) by means of at least two screws (5) and that the DIN rail holder (2) has a cuboid magnet (3) for attachment to metallic surfaces.

Description

Technical field:

[0001] The invention relates to a two-part holder for the orderly mounting of several folding current transformers, also known as continuity testers, in particular for use in electrical switch cabinets or similar installation situations.

[0002] The bracket is designed for both magnetic attachment to metallic surfaces and mounting on standardized DIN top-hat rails. State of the art:

[0003] In electrical control cabinets, clamp-on current transformers are often loosely mounted or unsecured in the wiring compartment. This leads to confusing cable routing and increases the risk of mechanical damage to the measuring instruments.

[0004] Known solutions offer neither a form-fitting mounting of several identical folding transducers nor a combined mounting option on magnetic surfaces and DIN rails. The problem underlying the invention is:

[0005] The object of the invention is to provide a compact, robust and easy-to-mount holder that enables the safe and orderly storage of several folding transducers and can be attached magnetically to metallic surfaces as well as mechanically to DIN rails.

[0006] Furthermore, the design of the holder is intended to prevent the folding converters from unintentionally falling out, while at the same time allowing for easy insertion and removal.

[0007] Solution to the problem:

[0008] The task is solved by a two-part bracket, consisting of a receptacle for a folding converter (1) and a DIN rail bracket (2). The receptacle (1) is screwed to the DIN rail bracket (2) by means of two socket head cap screws (5).

[0009] The DIN rail mounting bracket (2) has locking lugs that allow it to be attached to standard DIN DIN rails. Additionally, a rectangular magnet (3) is arranged in the DIN rail mounting bracket (2), which allows magnetic attachment to metallic surfaces.

[0010] The receptacle (1) has four form-fitting slots for receiving one folding transducer (4) each, so that a total of four folding transducers can be received.

[0011] The bracket is preferably manufactured using 3D printing with plastic. This material offers sufficient mechanical strength while maintaining elastic behavior of the locking tabs.

[0012] The two components are connected by two cylinder head screws (5) and corresponding threaded bushings (6). A further threaded bushing (6) is provided in the DIN rail mount (2) for attaching the rectangular magnet (3), into which a countersunk screw (7) is screwed. Advantages of the invention: • Combined mounting option on DIN rails and metallic surfaces • Form-fitting, orderly mounting of multiple folding transducers • Vibration-resistant mounting in the control cabinet • Easy installation and removal of the folding converters • Additive manufacturing enables cost-effective production and customization Exemplary embodiment of the invention:

[0013] The invention is explained below with reference to an exemplary embodiment shown in the figures. Fig. Figure 1 shows a perspective exploded view of the bracket. Fig. 2 shows a top view of the recording (1) & (2). Fig. Figure 3 shows a side view of the bracket (1) & (2). Fig. Figure 4 shows the back of the DIN rail mount (2) with the magnet (3) inserted. Fig.Figure 5 shows an exemplary configuration of the recording (1) & (2) with clamshell transducers (4).

[0014] The receptacle (1) has four receptacle grooves in which a folding transducer (4) is held in a form-fitting manner in each groove.

[0015] The DIN rail bracket (2) bears an embossed marking.

[0016] The DIN rail mounting bracket (2) has locking lugs for attachment to DIN rails. The magnet (3) is centrally located and secured by means of a countersunk screw (7).
