Abstract
An automatic changeover switch comprises an outer housing, a sliding cover, a secondary connecting terminal fixing plate, a secondary connecting terminal, a distribution line installed inside the outer housing, a controller and an actuating mechanism, wherein an opening is formed on the edge of one side of the front end surface of the outer housing, and a line outgoing hole communicated with the opening is formed on the edge of the lateral surface adjacent to the opening; the sliding cover can be installed at the opening part on the outer housing in a detachable manner; one end of the secondary connecting terminal fixing plate is fixed inside the outer housing; the secondary connecting terminal is installed on the external surface of the secondary connecting terminal fixing plate, and is positioned inside the opening on the outer housing. The automatic changeover switch provided by the utility model can seal the secondary connecting terminal inside the outer housing by utilizing the sliding cover, thus the problems of increasing failure rate caused by the bareness of the secondary connecting terminal, shortened service life of the products, poor security and the like can be avoided. In addition, since the secondary connecting terminal is positioned inside the outer housing, the appearance of the product becomes more artistic.
Description
Technical field
The utility model relates to a kind of power supply change-over device, particularly relates to a kind of automatic change-over.
Background technology
Automatic change-over is a kind of use terminal appliance widely, is mainly used in to connect or the active and standby ring current of disjunction, to guarantee the continuity of electric power safety and production.Fig. 1 is a kind of automatic change-over external structure schematic diagram of prior art.As shown in Figure 1, the automatic change-over of this prior art comprises shell 1; Be installed in the inside of shell 1, be used for product sampling and the required wiring line of control loop; The controller of be used to detect power supply, judging conversion; The actuator of power is provided for peripheral operation; And the secondary connection terminal 2 that interface is provided for user's secondary distribution.At present, there is following point in the automatic change-over of this prior art: consider the requirement of secondary connection outlet on the secondary connection terminal 2, and the user needs manual crimping secondary connection, therefore usually secondary connection terminal 2 is set directly at the outside of shell 1, will cause secondary connection terminal 2 not possess dirt exclusion capabilities like this, and the user in use also can very easily touch charged secondary connection terminal 2, especially under the more abominable industrial environment of dust, exposed secondary connection terminal 2 will increase the probability that automatic change-over breaks down, and reduce the useful life of product, fail safe, and the overall aesthetics of product is poor.
Summary of the invention
In order to address the above problem, the purpose of this utility model is to provide a kind of automatic change-over that can improve security of products, useful life and aesthetic property.
In order to achieve the above object, the automatic change-over that provides of the utility model comprises shell, slip lid, secondary connection terminal fixed head, secondary connection terminal, is installed in enclosure and is used for the required wiring line of product sampling and control loop, is used to detect power supply and judges the controller of conversion and the actuator that power is provided for peripheral operation; Described shell front end face one lateral edges position is formed with an opening, and the lateral edge position adjacent with opening then is formed with a wire hole that is connected with opening; Slip lid is installed in the opening part on the shell removably; One end of secondary connection terminal fixed head is fixed on the inside of shell; The secondary connection terminal is installed on the outer surface of secondary connection terminal fixed head, and is positioned at the inside of shell upper shed.
The area of described opening is greater than the external dimensions of secondary connection terminal.
Described secondary connection terminal is a plug-in.
The automatic change-over that the utility model provides can utilize plug-type slip lid the secondary connection terminal to be enclosed in the inside of shell, even under the more abominable industrial environment of dust, also can avoid problems such as the exposed failure rate rising that causes, product shortening in useful life and poor stability like this because of the secondary connection terminal.In addition, because the secondary connection terminal is positioned at the inside of shell, so the profile of product is more attractive in appearance.In addition,, therefore when it breaks down, be easy to change,, enhance productivity so can shorten the operating time because the secondary connection terminal is a plug-in.
Description of drawings
Fig. 1 is a kind of automatic change-over external structure schematic diagram of prior art.
The automatic change-over external structure schematic diagram that Fig. 2 provides for the utility model.
Fig. 3 is significant points structural representation in the automatic change-over shown in Fig. 2.
Embodiment
Below in conjunction with the drawings and specific embodiments the automatic change-over that the utility model provides is elaborated.
As Fig. 2～shown in Figure 3, the automatic change-over that the utility model provides comprises shell 3, slip lid 4, secondary connection terminal fixed head 5, secondary connection terminal 6, be installed in shell 3 inside is used for the required wiring line of product sampling and control loop, is used to detect power supply and judges the controller of conversion and the actuator that power is provided for peripheral operation; Described shell 3 front end faces one lateral edges position is formed with an opening 7, and the lateral edge position adjacent with opening 7 then is formed with a wire hole 8 that is connected with opening 7; Slip lid 4 is installed in opening 7 places on the shell 3 removably; One end of secondary connection terminal fixed head 5 is fixed on the inside of shell 3; Secondary connection terminal 6 is installed on the outer surface of secondary connection terminal fixed head 5, and is positioned at the inside of shell 3 upper sheds 7.
The area of described opening 7 is greater than the external dimensions of secondary connection terminal 6.
Described secondary connection terminal 6 is a plug-in.
When the user need carry out secondary connection on the automatic change-over that the utility model provides, at first pin slip lid 4 and outwards pulling, thereby it is taken off from shell 3, so that opening 7 and the secondary connection terminal 6 that is positioned at opening 7 inside expose, at this moment, the user just can carry out the secondary connection operation, and by wire hole 8 outlets, and then the edge of slip lid 4 along opening 7 inwardly pushed, can finish the secondary connection process up to covering whole opening 7, so process is very simple and convenient.
