Embodiment
With reference to Fig. 1, electric installation according to the present invention consists essentially of an instruction and/or signalling 2 and a coupling assembling 4 that detachably is connected with it.In the illustrated embodiment, an instruction and a signalling that constitutes as illuminated push button is shown.
The fixed part 10 that this device is connected forepiece 6 and functional part 8 by a forepiece that constitutes as illuminated push button 6, three functional parts 8 and one basically.As functional part 8, for example be provided with one and be used for the separately normally closed interlock parts of current circuit, normally open contact parts and a luminous component that is used for on-the-spot release announcement that is used for the remote notify of release signal.The respective combination of the forepiece 6 under the combination of each functional part 8 and can freely be selected according to required function.
Preferably functional part 8 has same structure relatively with the exterior contour of housing parts at least.They have the housing of flat basically rectangular parallelepiped shape, these housings have the aperture that is used to operate push rod or luminous component on narrow end surface on them, on their side leptoprosopy, have position each other relative, introduce the aperture to the cable of connecting portion especially bar clamp (being used for traditional wired), and have the introducing aperture of the screwdriver that is used to operate bar clamp at their following leptoprosopy.Below each cable is introduced the aperture, be configured with a buckling groove 12 in this embodiment, be used for fixing coupling assembling 4.
Coupling assembling 4 comprises the housing 40 of a rectangular parallelepiped shape, it thereon side have: mechanical connecting device 41 (Fig. 2) is used for removably coupling assembling 4 being fixed at least one functional part 8; And arrangements of electric connection 42 preferably, be used for coupling assembling 4 and be communicated with electric contact between at least one functional part 8.At this, mechanical connecting device 41 on one side preferably includes three fixing rear solid end 41b that respectively separate each other by a free space 41a, have the snap-arms that resilient movement ground constitutes but reach on a side on its opposite, it has three clamping projection 41c (Fig. 3) that respectively separate each other by a free space 41a.Preferably snap-arms has the part 41d that receives an instrumental purpose, by this instrument the snap-arms bending is connected to discharge clamping.Preferably these parts 41d is made to and is used to receive the slot shape accommodation section that a screwdriver is intervened.Yet also can consider the part 41d of other form, as be used for manual projection.Clamping projection 41c and rear solid end 41b are configured with the upper surface inclined downward towards coupling assembling 4 in the top side, so that by instruct and/or the simple press each other of signalling 2 and coupling assembling 4 is connected to each other them by the mechanical snap connection.
Arrangements of electric connection 42 advantageously constitutes by contact spring, and they form with logic circuit unit in enclosure interior and are electrically connected.Preferably contact spring constitutes power transmission chain ground and removably is fixed in the housing, reaches on the other hand the adding by contact spring and takes the increase and the minimizing that can realize contact point simply away so that can realize reliable contacting on the one hand.In a preferred implementing form, coupling assembling 4 has the width of three functional parts 8 and has six holes that are used to receive or pass contact spring altogether.At this, these holes are so positioned, promptly contact spring directly reaches in the screwdriver intake of functional unit and is pressed in there on the head of screw of binding clip of functional part 8 when coupling assembling 4 is fixed on the instruction and the functional part 8 of signalling 2, reaches to have guaranteed that thus coupling assembling 4 is connected with conduction between the functional part 8.For fixedly connected assembly 4 mechanically, maybe with this coupling assembling from the below almost parallel be pressed on the bottom surface of functional part 8, or the rear solid end 41b that is fixed hooks in the buckling groove 12 on functional part 8 one sides and snaps onto the buckling groove that is arranged in the opposite 12 of functional part 8 to the direction deflection of functional part 8 up to the snap-arms on coupling assembling 4 opposites with the protruding 41c of its clamping.Basically side by side produce machinery and electric connection thus.Coupling assembling 4 has acquisition equipment 45 in the location hole 44 outstanding, that be inserted into functional part 8 downsides on the side of functional part 8 at it, is displaced sideways preventing.The position that can additionally guarantee the electric installation that this modularization constitutes thus is mobile unintentionally to prevent, this moves unintentionally can cause functional fault.Advantageously, location hole 44 is configured to the enlarged that the angle is arranged (Fig. 3 and Fig. 4) of screw tool bore.The buckling groove 12 of each functional part 8 preferably has the boundary wall 8a of side, they equally for prevent between coupling assembling 4 and instructions and the signalling 2 be displaced sideways and/or rotate and with the 41c mating reaction (Fig. 4) of rear solid end 41b or clamping projection.
In order to guarantee this electric installation in the protection against electric shock reliability aspect the lateral cable introducing hole of functional part 8, the clamping projection 41c of rear solid end 41b and snap-arms constitutes in this wise, and promptly cable introducing hole is closed in coupling assembling 4 assembled states.For this reason, rear solid end 41b or clamping projection 41c has been configured backplate shape extendible portion.In another embodiment, rear solid end 41b and clamping projection 41c introduce in the hole for the cable that fixedly connected assembly 4 also can directly snap in functional part 8, and guarantee the protection against electric shock reliability in this wise.
Fig. 2 represents the electric installation of the present invention according to Fig. 1, and the fixing functional part 8 in one of them side does not have the cover part.Here can be clear that at coupling assembling 4 assembled states, the clamping projection 41c that is arranged on the opposite of fixing rear solid end 41b and snap-arms is entrapped in the following buckling groove 12 of the cable entrance hole that is arranged in functional part 8 of functional part 8 every sides.And can see that what the contact spring on the head of screw of the binding clip by being pressed in functional part 8 between coupling assembling 4 and the functional part 8 was realized contacts.
The bus connecting device 43 of a gang socket form also is shown in Fig. 1 and 2 in addition, is used to hold a male component.
Advantageously, can realize the connection of a serial bus-bar system, especially the connection of AS-i or special-shaped bus (Profibus).To this other corresponding bus connecting device can certainly be set, as the cutter shape contact terminal on the AS-i two-conductor line or simple screw terminals or similar device.
Fig. 3 expresses coupling assembling 4 once more dividually.
