Description
Technical field
The utility model relates to fire-fighting domain, is specifically related to the controller of preventing fires.
Background technology
Fire detector is at present already used very universal, and its distributed number is more, and detector generally all can be concentrated and be connected to controller and control; Wiring relative complex in the controller, existing controller wiring sealing is poor, and often just with circuit access control chamber door inside, the wiring position does not have seal protection, causes the early stage damage of circuit easily.
The utility model content
The utility model provides a kind of wiring construction of controller of good airproof performance at above-mentioned the deficiencies in the prior art.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of wiring construction of controller, comprise the casing joint of installing on the control cabinet casing, the casing joint is female adapter, nipple is male connection, the nipple engagement is installed in the casing joint, and O-ring seals is installed at the position that nipple and casing joint join; The nipple inner hollow, hole wall arranges step, on the hole wall step sealing ring is installed, and the sealing ring upper and lower side all is equipped with plain washer, and the sealing ring top is equipped with clamp nut;
The cable of controller passes above-mentioned clamp nut successively, sealing ring, nipple, O-ring seals and casing joint.
Further be: the endoporus aperture of above-mentioned sealing ring is 7.4mm.
Further be: above-mentioned casing joint arranges the top with the control cabinet casing.
The beneficial effects of the utility model are:
The wiring construction of the utility model controller, by with sealing ring, packing ring is pressed, and nipple is sleeved on the cable, compresses by clamp nut at last, has guaranteed the firm sealing property of whole cable wiring construction; Simultaneously, owing to be to fix by tightening of clamp nut finally, the whole erection fixation procedure is very simple and convenient.
Description of drawings
Fig. 1 is front view of the present utility model.
Description of reference numerals:
The 1-clamp nut, 2-plain washer, 3-sealing ring, 4-nipple, 5-O shape sealing ring, 6-casing joint.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described:
As shown in Figure 1, it shows a kind of embodiment of the present utility model, the wiring construction of the utility model controller, comprise the casing joint of installing on the control cabinet casing 6, casing joint 6 is female adapter, nipple 4 is male connection, and nipple 4 engagements are installed in the casing joint 6, and nipple 4 is installed O-ring seals with the position that casing joint 6 joins; Nipple 4 inner hollow, hole wall arranges step, and sealing ring 3 is installed on the hole wall step, and sealing ring 3 upper and lower sides all are equipped with plain washer 2, and sealing ring 3 tops are equipped with clamp nut 1;
The cable of controller passes above-mentioned clamp nut 1 successively, sealing ring 3, nipple 4, O-ring seals and casing joint 6.
The endoporus aperture of above-mentioned sealing ring 3 is 7.4mm.
Above-mentioned casing joint 6 arranges the top with the control cabinet casing.
During above-mentioned controller wiring, at first open the controller door, from above-mentioned wiring construction, unload lower compression nut, packing ring and sealing ring, the order according to clamp nut-packing ring-sealing ring-packing ring is enclosed within on the cable one by one then, adjusts inlet wire length, tightens clamp nut.
By reference to the accompanying drawings the utility model preferred implementation has been done detailed description above, but the utility model is not limited to above-mentioned execution mode, in the ken that those of ordinary skills possess, can also under the prerequisite that does not break away from the utility model aim, make a variety of changes.
Do not break away from design of the present utility model and scope and can make many other changes and remodeling.Should be appreciated that the utility model is not limited to specific execution mode, scope of the present utility model is defined by the following claims.
