Abstract
The utility model discloses a fire alarm control unit's return circuit shielding structure solves distributed return circuit shielding structure and has the problem that the installation is troublesome, production efficiency is low. The utility model discloses a preceding load bearing seat and rather than the back load bearing seat of solid structure as an organic whole, set up a plurality of butt joint holes of realizing board and board butt joint after being used for the perpendicular male of circuit board installation guide rail groove and being used for the circuit board to insert in the preceding load bearing seat respectively, be equipped with on the back load bearing seat and be arranged in preceding load bearing seat and the fixed screw fixing hole to the controller of back load bearing seat. The utility model relates to a rationally, circuit board installation and butt joint are convenient, the overall arrangement is pleasing to the eye, efficiency is higher when dependable performance, mass production.
Description
Technical field
The utility model relates to the loop shielding construction of a kind of fire alarm control unit.
Background technology
At present, in terms of fire alarm control unit, its loop mounting means, majority is utilized on controller dispersion and installs associated circuit board, and then the conducting of associated circuit board linearly connected is formed loop by recycling wire.This loop generation type, not only installs trouble, easy connection error, and layout is unsightly, even also affect the efficiency of batch production.
Utility model content
The purpose of this utility model is to provide the loop shielding construction of a kind of fire alarm control unit, solves the problem that distributing loop shielding construction exists installation trouble, production efficiency is low.
For achieving the above object, the technical solution adopted in the utility model is as follows:
The loop shielding construction of a kind of fire alarm control unit, including front load bearing seat and the rear load bearing seat of the structure that is solidified as a whole with it；Described front load bearing seat offers multiple installation guide-track groove being inserted perpendicularly into for circuit board respectively and realizes, after circuit board inserts, the butt hole that plate docks with plate；Described rear load bearing seat is provided with the screw fixing hole for front load bearing seat and rear load bearing seat being fixed in controller.
Compared with prior art, the utility model has the advantages that
The utility model is by designing a kind of centralized loop shielding construction, and not only circuit board is easy for installation, can realize the normal docking between each circuit board, and layout is attractive in appearance, dependable performance, and meanwhile, when producing in enormous quantities, efficiency is the highest.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Wherein, corresponding entitled of reference:
Load bearing seat before 1-, load bearing seat after 2-, 3-installs guide-track groove, 4-butt hole, 5-screw fixing hole.
Detailed description of the invention
The utility model is described in further detail with embodiment in explanation below in conjunction with the accompanying drawings, and mode of the present utility model includes but are not limited to following example.
Embodiment
As it is shown in figure 1, the utility model is mainly used in the loop shielding aspect of fire alarm control unit, it includes front load bearing seat 1 and the rear load bearing seat 2 of the structure that is solidified as a whole with it；Described front load bearing seat 1 offers multiple installation guide-track groove 3 being inserted perpendicularly into for circuit board respectively and realizes, after circuit board inserts, the butt hole 4 that plate docks with plate；Described rear load bearing seat 2 is provided with the screw fixing hole 5 for front load bearing seat and rear load bearing seat being fixed in controller.
The utility model is in use, utilize and guide-track groove 3 is installed by the insertion of each circuit board tile vertically, then the connection between each circuit board is realized by butt hole 4 so that it is form loop, be screwed hole 5 the most again and be fixed in fire-alarm by whole loop shielding construction.
According to above-described embodiment, just can preferably realize the utility model.
