Abstract

The utility model discloses a switching device is inserted to boat, including explosion -proof casing, the leading -out terminal has been seted up to one side of explosion -proof casing, is provided with on the leading -out terminal to insert the inside switching front end of explosion -proof casing, and the switching front end passes through the sealing washer, and to connect the switching terminal, and multicore shielded cable draws forth in explosion -proof casing, fix on the switching end through the switching front end, the utility model discloses only have a leading -out terminal, and fix multicore shielded cable according to the wiring requirement and draw again at the switching end, when guaranteeing the product uniformity, not only satisfied the leakproofness requirement but also guaranteed the reliability, improved work efficiency like this.

Description

A kind of air plug switching device
[technical field]
The utility model belongs to automation field, is specifically related to a kind of air plug switching device.
[background technology]
Existing air plug switching device is the cable of drawing from explosion-proof casing, and through solidus bolt, arrive outside, cable is drawn from the two ends of explosion-proof casing respectively, more as required, is connected with external equipment; Need site operation, carry out welding and assembling, this assembly method difficulty is large, and reduces the reliability of product.
[utility model content]
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of air plug switching device, can solve the difficulty of site operation, can carry out product wiring, replacing fast and effectively, improves product hermeticity, reliability, standardization level.
In order to achieve the above object, the utility model comprises explosion-proof casing, the side of explosion-proof casing offers leading-out terminal, leading-out terminal is provided with the switching front end of inserting explosion-proof casing inside, switching front end is connected with switching end, and switching is provided with air plug seat in front end, air plug head is provided with in switching end, air plug head inserts in air plug seat, and air plug head is connected with shielded multiconductor cable, and the extraction wire in explosion-proof casing is connected with air plug seat by switching front end.
Described air plug seat is fixed in switching front end by pressure ring.
Described shielded multiconductor cable is welded on the air plug head in switching end.
Described switching front end and switching end are connected by screw.
Be provided with sealing ring between described switching front end and switching end, sealing ring is the rectangular seal identical with exterior end molded line of transferring with switching front end.
Compared with prior art, the utility model offers leading-out terminal in the side of anti-guarantor's housing, extraction wire in explosion-proof casing is connected with air plug seat, shielded multiconductor cable is connected with air plug head, air plug seat and air plug head are placed in switching front end and switching end respectively, air plug head is inserted in air plug seat, realize switching front end to be connected with switching end, when Product checking overhauls, disconnect switching front end and switching end port, housing and switching connector assembly two large divisions can be divided into, carry out modularization replacing, like this while ensuring product consistency, both meet sealing requirements and in turn ensure that reliability, improve operating efficiency.
Further, switching front end of the present utility model and switching end are connected by screw, and the fastness of transfer when ensure that use front end and switching end, is not easy to come off.
[accompanying drawing explanation]
Fig. 1 is structural representation of the present utility model.
[embodiment]
Below in conjunction with accompanying drawing, the utility model is described further.
See Fig. 1, comprise explosion-proof casing 1, the side of explosion-proof casing 1 offers leading-out terminal, leading-out terminal is provided with the switching front end 2 of inserting explosion-proof casing 1 inside, switching front end 2 has been connected by screw switching end 4, switching is provided with air plug seat in front end 2, air plug seat by pressure ring 5 be fixed on conversion front end in 2, air plug head is provided with in switching end 4, air plug head inserts in air plug seat, air plug head is welded with shielded multiconductor cable, extraction wire in explosion-proof casing 1 is connected with air plug seat by switching front end 2, sealing ring 3 is provided with between switching front end 2 and switching end 4, sealing ring 3 is the rectangular seal identical with the outside molded line of end 4 of transferring with switching front end 2.
Extraction wire in housing is connected on the air plug seat in switching front end 2 by the utility model, air plug head in switching end 4 connects shielded multiconductor cable, switching front end 2 and switching end 4 are connected by screw, when constructing at the scene, switching front end 2 is only needed to be connected with switching end 4, inner air plug head is so just made to insert air plug seat inner, realizing circuit closes, when detecting maintenance, pull down screw, can disconnect, by production sharing housing (containing switching front end) and switching connector assembly two large divisions, carry out modularization replacing.
The site operation that the utility model solves transmitter outlet method is difficult, and reliability is low, and the problem that the degree of product standardization is low.
