Mini compact relay

The innovation concerns a mini contact relay with a box-shaped Housing for receiving the excitation winding, the yoke and the armature as well as the switching and contact springs, their Connections reach through walls of the housing tightly and a slip-on cover that can be plugged onto the housing via the open side of the same.

In known miniature relays, the connections are through the side walls the housing passed through. In addition, the connections have bends at the inner ends to which the excitation winding attacks or switch springs or stationary switch contacts are attached. To achieve the necessary tightness and to The connections are encapsulated by the housing material when they are fixed in the housing walls.

It has been shown that this type of accommodation of the connections makes a large manufacturing effort for the relay necessary.

It is the task of the innovation to simply arrange the connections tightly and securely in the housing of the relay.

According to the innovation, this object is achieved in that the housing has a tub open on one side and two on top of each other opposite side walls of the same externally firmly attached plate parts or the like. is formed and that in the common dividing surfaces of side walls and plate parts the connections of the switching and Kbntaktfedem and the excitation winding are firmly and tightly arranged. Is expedient the tub is formed by a flat bottom part and side walls that are permanently molded on this. That way, needs it is just a simple plug-in process to define the connections and a gluing or welding process for the plate parts. It goes without saying that by choosing side walls and plate parts of any thickness, a sufficient mechanical and electrical safety can be taken into account and a compact design can be achieved.

In the formation of the relay it is provided that the connections in to introduce prepared recesses in the side walls and / or the plate parts in a form-fitting manner, with the expedient

j Connections through side wall brackets engaging in holes in the same Approaches, formations or the like. on the side walls

"can be kept shift-free.

In further training, the plate parts are at least in sections protruding from the open side of the tub

formed and the preceding sections defining the t

Yoke and the armature retaining spring made usable.

It is also provided that the plate parts and the transversely to these extending side walls of the tub at the ends facing away from the bottom part circumferentially a fold for have the inclusion of a Stülpoeckels, the relay with several sets of springs, if necessary, has an integrally formed web or several web sections that go into the bar protrude between the sets of springs as an electrical isolating element. The web or the web sections enable compliance predetermined air and creepage distances.

The innovation is illustrated in the drawing using an exemplary embodiment.

In the figures, 1 denotes a trough on the side walls 1 ^{1 of} which plate parts 2 are firmly attached to the outside, e.g. by ultrasonic welding, which together form an essentially box-shaped housing for receiving the excitation winding 3 with core 3 ¹ , the yoke 4 and the armature 5 form. Furthermore, the housing 1 accommodates connections 6, 7, 8 and 9 for the switching ^{springs 6 1} and contact springs 7 ′ and 8 ¹ as well as the field winding 3. According to the innovation, the connections 6, 7, 8, 9 are arranged in the common separating surfaces of the side walls 1 'and the plate parts 2, which for this purpose engage positively in prepared recesses 11 in the side walls 1' or the plate parts 2 and in these through on the side walls 1 'Shaped pins 10 are held. The plate parts 2 have sections 12 protruding beyond the open side of the tub 1 which, as shown in particular in FIG. 1,

the yoke 4 and the armature retaining spring 13 overlap and in the housing determine. The sections 12 are also with box grooves

The connections 6 to 9 must first be introduced into the prepared recesses 11 of the side walls 1 'to form the housing and by subsequent application and welding of dfcdr plate parts 2 to be fixed to the side walls 1 '. the Connections 6 to 9 arranged in this way prevent or reliably prevent the entry of solder and flux into the Casing. The connections 6 to 8 are bent towards each other at their inner ends and carry switching springs 6 'and contact springs 7 ', 8'.
