Abstract

The interlocking structure consists of an appendage (2) situated at the lower end of a quick connection key (1) and joined thereto by means of an area (4), which confers flexibility to that area and permits the displacement of the entire appendage (2) to get closer to the key (1) upon pressing thereupon or separating it and returning it to its starting position by ceasing to apply pressure, pressure which can be applied on the appendage (2) or on the hook (3) with which said appendage finishes at its end. The key (1) is equipped at its upper end with a hollow (8) for the insertion of the end of the wire to be connected, and is placed on a U-shaped housing (5) of the body (6) of the mechanism, so that it can swing about an axis (7) of rotation. In the swinging displacement of the key and upon approaching the external face (6a) of the body (6), the end hook (3) of the appendage (2), which constitutes the interlocking, comes into contact with the lower external face (9a) of a lower projection (9), central and symmetrical, of said body (6), sliding therealong until the aforementioned hook (3) is held back by clipping on the upper edge (9b) of the projection (9), the key being immobilized. Once the hook (3) has been held back on the upper edge (9b) of the projection (9), the appendage (2) being pressed, the unclipping of the hook (3) is caused given the elasticity of the material, said key freeing itself and permitting its swinging.

Description

The interlocking structure that is used for the rapid connecting key of electric mechanism

Technical field

The present invention relates to be used for the interlocking structure of rapid connecting key, these rapid connecting keys are arranged on the electric mechanism that is used for controller that is used for such as switch, button, cross bar switch (cross over switch), receptacle outlet and analog, and their principal character is as described below.

Background technology

People need shorten setter as much as possible and be used for correctly carrying out with for example in the time that is connected of the contacted various conductor lines of main body of the electric mechanism of the application described in the leading portion, and this needs cause people to develop being used for the different device of this actual purpose.

We can pay special attention to known rapid connecting key in these devices, these connecting keys are by inserting its set for this purpose hollow bulb with the end of the lead that will connect simply, be shifted to maintain aforementioned cable and to guarantee its location and activity along swaying direction then, guarantee that simultaneously connecting key itself no longer becomes outer barrie (because it is in close proximity to the wall of mechanism body), just can make aforementioned operation be achieved.

However, still there is following shortcoming in these devices, and promptly it may disconnect in the original institute of lead junction and unexpectedly separate with aforementioned body, and may leave its housing, thereby disconnects the connection of electric mechanism and make it be in incorrect non operating state.

Summary of the invention

Device object of the present invention provides a kind of reality effective and very simple simultaneously solution, because its feature is a kind of like this interlocking structure, it is positioned at the lower end that will be fixedly coupled key, and by preventing the displacement of connecting key anything unexpected on the protuberance that is clamped in place, mechanism body bottom.

But the design of this interlocking structure allows to constitute with regard to release by means of operator's manual activation at any time the outer member of the hook of interlocking structure itself, and allow connecting key to separate simultaneously by means of its swing, to pull down lead or when not connecting lead as yet, to put lead.

Description of drawings

To enclose accompanying drawing in order helping to describe the interlocking structure that is disclosed, in the explanation mode practical embodiments that is provided with according to a rapid connecting key of interlocking structure of the present invention to be shown in the accompanying drawings.

Fig. 1 is the cutaway view of mechanism body, and rapid connecting key is positioned at the one side, is in initial open position, can place the lead that will connect or the end of electric conductor in this position;

Fig. 2 is the complementary view of last accompanying drawing, and wherein connecting key is towards its link position displacement;

Fig. 3 is the enlarged detail that connecting key forms the zone of interlocking structure, is in position before on its protuberance that is clamped to place, body bottom;

Fig. 4 is similar to the detail drawing that being similarly of Fig. 1 and Fig. 2 analysed and observe, and connecting key is shown fixes by its interlocking structure; And it is last

Fig. 5 is mechanism body solid and partial sectional view, wherein connecting key interlocking, and this is also to draw to analyse and observe mode at the place of cutting open identical with body.

Embodiment

According to described accompanying drawing, be used for comprising the annex 2 of the lower end that is positioned at rapid connecting key 1 such as the interlocking structure of the rapid connecting key of the electric mechanism of switch, button, cross bar switch, receptacle outlet and analog, this annex 2 finishes with the hook 3 that inwardly protrudes out, and 4 be attached to rapid connecting key 1 by the zone, zone 4 provides flexible for described linking part, and whole annex 2 can be when it is pressed or pushes be moved towards the body of rapid connecting key 1, and when stopping to apply this pressure, turn back to its starting position on its hook 3.

Rapid connecting key 1 is placed on the U-shaped housing 5 on mechanism body 6 both sides.In various accompanying drawings, at the housing of that side of not placing rapid connecting key 1 as seen, and block housing placing connecting key 1 and the connecting key place's connecting key that freely swings thereon, but the pivot center 7 of rapid connecting key 1 in its oscillating motion represented with the spike line.

The hollow bulb 8 on the top of rapid connecting key 1 also can be seen in different accompanying drawings, the end (not shown) of the lead that connects inserts this hollow bulb, this hollow bulb changes the position when connecting key 1 is swung on aforementioned axis 7, the outer lateral surface 6a of more close body 6, as from appreciable Fig. 2 and 4, and this hollow bulb is used for maintaining lead to connect.

In this swing displacement of rapid connecting key 1, all highlighted among Fig. 1 and 2 with arrow, the hook end 3 of annex 2 contacts with the following outer surface 9a of the following protuberance 9 of body 6, slide along described surface, as visible in the close up view of Fig. 3, till hook 3 when rapid connecting key 1 is maintained static hooks above the top edge 9a at this time protuberance 9, just can't throw off again with the cable that carries out its connection from attached suitably.

In case clamp, the hook 3 of the annex 2 of the interlocking structure between the lower surface 2a that constitutes described annex and the upper surface 9b of following protuberance 9 can be owing to the elasticity of the material of the whole rapid connecting key 1 of formation from the top edge 9b disengagement of protuberance 9.

After having implemented this action, described connecting key 1 can be swung once more and itself can separate with the side 6a of body 6, and this just can pull down the connected lead of possibility or put a lead and connect.

Object of the present invention has fully been described, what should be noted that is, its essence that any variation of used shape, size, outward appearance and material type can not change in appending claims to be summarized by any way in the practical embodiments to these connecting keys of being provided with interlocking structure.
