Abstract
The utility model discloses a universal change-over switch. The technical problem to be solved is to provide an anti-contact universal change-over switch. To solve the above problem, according to the technical scheme of the utility model, the universal change-over switch comprises a handle, a rotating shaft and a multilayer contact system which comprises contact base seats, and the universal change-over switch is characterized in that the inside of each contact pedestal is provided with a wiring groove, and an insulated protecting cover having a shape matched with the wiring groove is disposed over the wiring groove and provided with threaded holes and wiring holes. The universal change-over switch has the advantages that a traditional simple open-type installation method is changed, and an enclosed installation method is adopted; and a connection sheet between two contacts is inserted into one wiring groove and covered by one insulated protecting cover, so that the risk that fingers touch contact points is completely avoided, accuracy and efficiency of installation are increased, and the problem of an accident electric leakage and the like due to that contact heads are defaced or wet is prevented by utilization of the insulated protecting covers.
Description
Technical field
The utility model relates to a kind of low-voltage electrical apparatus, is specially a kind of universal seclector.
Background technology
Universal seclector is the multiloop control apparatus that the contact assembly closed assembly by many groups same structure forms.It is comprised of parts such as operating mechanism, positioner, contact, contact system, rotating shaft, handles.The contact is in the insulation contact pedestal, is the double break contact bridge architecture, the synchronism when moving contact is designed to automatic regulating with the assurance break-make, and fixed contact is contained in contact shoe.Rely on cam and support to operate during use, control the closed and disconnected of contact.
The common open line connection of general employing between tradition universal seclector two contacts, due to outside wiring position is exposed to, when product carries out the circuit fitting operation, be easy to cause wiring position to contact with operator's finger, there is larger security risk, simultaneously, wiring position is naked and lug plate is outside exposed, also be easy to occur stained, getting wet causes the appearance of the problems such as unexpected electric leakage.
The utility model content
The technical problems to be solved in the utility model is to provide a kind of universal seclector of anti-contact.
For addressing the above problem, the technical solution adopted in the utility model comprises handle, rotating shaft and multilayer contact system, described multilayer contact system comprises contact pedestal, it is characterized in that: be provided with connecting groove in described contact pedestal, described connecting groove top is provided with the insulation protecting cover of fitting mutually with its shape, and described insulation protecting cover is provided with screw hole and wiring hole.
Described universal seclector is characterized in that: the upper and lower side of described connecting groove arranges at least one fixture block.
Described universal seclector is characterized in that: on the screw hole of the bottom of described contact pedestal, concave station is set.
Described universal seclector is characterized in that: described insulation protecting cover is connected with described contact pedestal buckle.
Described universal seclector is characterized in that: described insulation protecting cover is that transparent or semitransparent insulating material is made.
Universal seclector of the present utility model is eliminated the simple and crude open installation method of tradition, take enclosed installation method, brace between two contacts is embedded in connecting groove, then cover the insulation protecting cover, thoroughly isolate the touching risk of finger and contact point, and improve accuracy and the efficiency of installing, utilize the insulation protecting cover to guarantee that the contact head appearance is stained, getting wet causes the generation of the problems such as unexpected electric leakage.
Description of drawings
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1, Fig. 2 are structural representations of the present utility model;
Fig. 3, Fig. 4 are exploded views of the present utility model.
Embodiment
as shown in Figures 1 to 4, universal seclector of the present utility model, comprise handle 1, rotating shaft 2 and multilayer contact system, described multilayer contact system comprises contact pedestal 3, fixed contact is set in the seat, the left and right sides of every layer of contact pedestal 3 (is conventional structure, not shown in FIG.), correspondence arranges terminal screw (for conventional structure on fixed contact, not shown in FIG.), be connected with the copper sheet wire between terminal screw and (be conventional structure, not shown in FIG.), be provided with the connecting groove 4 that adapts with the copper sheet wire between the seat, the left and right sides of described contact pedestal 3, described connecting groove 4 tops are provided with the insulation protecting cover 5 of fitting mutually with its shape, described insulation protecting cover 5 is connected with described contact pedestal 3 buckles.Described insulation protecting cover 5 is made for transparent or semitransparent insulating material, can see the terminal screw of the inside clearly, the convenient installation.Be provided with screw hole 6 and wiring hole 7 on insulation protecting cover 5, can directly wire be stretched into wiring hole 7 during installation, screwdriver stretches into screw hole 6 and directly tightens, and plays from the effect of the touching risk of finger and contact point.Wiring hole 7 also plays the effect to the wire location simultaneously, improves accuracy and the efficiency installed.
The upper and lower side of described connecting groove 4 arranges two fixture blocks 8, can block the copper sheet wire, plays the convenient stable effect of installing and keeping the copper sheet wire.
Concave station 9 is set on the screw hole of the bottom of described contact pedestal 3.The screw rod and the nut that are used for connection multilayer contact system can be placed in one, and play anti-cooperation of colliding with.
The above is only preferred embodiment of the present utility model, not in order to limiting the utility model, all any modifications of doing within spirit of the present utility model and principle, is equal to and replaces and improvement etc., within all being included in protection range of the present utility model.
