Terminal carrier, especially for single-pole bus terminals with a rectangular cross-section

The innovation relates to a terminal carrier , in particular for single-pole bus terminals with a rectangular cross-section, for attachment to a TragsChilene, consisting of an insulating strip that can be placed on the rail, which has a longitudinal groove on its upper side to accommodate a correspondingly profiled base of the bus-connecting terminal and on the underside holding means for the has screwless fastening on the carrier rail «,

For screwless attachment of the terminal carrier respectively. the Insulating strip, it is known that the foot of the terminal support has a dovetail profile that corresponds to a correspondingly profiled support rail. This means that the known terminal support can only be attached to the mounting rail by sliding it on and cannot easily be attached to the rail at a later date and between bus terminals that have already been laid. Apart from that the well-known terminal requires a special version of a mounting rail that can only be used to accommodate similar terminal carriers with a profiled foot «

The innovation solves the problem of a terminal support of the type described screwless at any free point on the mounting rail, also subsequently insert from the front without having to move other terminal carriers, namely in connection with a simple, commercially available rectangular mounting rail.

The solution is that the terminal carrier using an elastic, preferably thermoplastic, flame-retardant Insulating material # s is extruded as a U-shaped profile, such that whose resilient leg parts (If) have claw-like organs (la), Via which the terminal carrier (1) together with the bus terminal (2) can be split open onto the mounting rail (3), the claw-like Organs at a distance equal to the thickness of the mounting rail stop strips (Ib) assigned. These stop bars, between the and the claw-like Organs that the mounting rail lays down when the terminal carrier is blown open also have the task of carrying the trunks to be fixed between the resilient leg parts of the terminal support at a distance from the bottom of the U-shape, according to the U-shape of the extruded terminal carrier forms an air channel to dissipate the heat from the current.

According to a further proposal are the claws of the terminal carrier beveled inwards, which makes it easier to snap it onto the mounting rail and remove it using a tool.

In the drawing, embodiments of the subject of the innovation are shown, namely show

Fig.l is a perspective view of a on a mounting rail with a rectangular cross-section blown open terminal carrier with screwed-on bus terminal,

Fig.2 a vertical section through a terminal carrier with screwed-on terminal block,

Abbο 3 is a vertical S _c hnitt by a clamp support

with inserted T-shaped bus terminal ,, and Fig.4 a vertical section through a terminal carrier with a bonded bus terminal »

In /.-Fig.l, 1 represents the U-shaped terminal support, on which the bus terminal 2 is attached. The terminal support 1 is snapped onto the mounting rail 3 in the groove Id of the leg parts If and supported by the claw parts la and the stop strips Ib. The stop bars Ib limit the EinspreQg movement in such a way that that between the leg parts If and above the mounting rail j5 an air duct remains through which electrical heat can be dissipated.

So that the terminal carrier 1 can be forced in more easily, the claw-like organs la are beveled inwards. On the front upper edge part of the client carrier 1, number markings are arranged, which are used in a known manner to identify the line cores. The groove Ic on the upper side of the terminal carrier 1 serves as an anti-twist device in the version with screwed-on terminal 2. In Fig.2, the described details can be seen in section. As a clamping screw is a countersunk screw mounting 2a is made space-saving reasons provided, whose length is such that they can not touch the support rail 3 during falling out of its bore and cause short circuiting ,,

Another embodiment is shown in Fig.5 · The one already described The terminal support 1 here has a C-shaped longitudinal groove Ic on its upper side. The bus terminal 2 with a T-shaped cross-section is inserted with its foot part 2b into the groove Ic and thus held in a form-fitting manner »By mechanical pretensioning of the thermoplastic material, a sufficiently secure fit of the terminal 2 is guaranteed.

Figure 4 illustrates the example of a bonded bus terminal 2 in a deeper longitudinal groove Ic of the terminal carrier 1. As an adhesive can e.g. a suitable two-component adhesive, casting resin or The like. Can be used. This version is applicable if the Bus terminal 2 is provided with a rectangular cross-section.

The advantages achieved with the innovation are that the new terminal support enables single-pole bus terminals commercially available mounting rails with rectangular cross-section, which are used in small distributions and meter boards are generally already in place;

Can be fastened from the front without screws and time-saving by blowing it open or pushing it on with a single movement. This simple assembly process is _s related, given the ever-narrowing space beneficial to the larger assembly by the higher electrification. Unscrewing or sliding on ^ which causes considerable difficulties, especially with subsequent expansions and changes to the electrical system _{3, is} omitted., The collective terminal is economical

economically producible by extrusion, especially if a Terminal support is used with a T-shaped foot and the bus terminal is glued into a longitudinal groove on the top of the terminal support will.
