Embodiment
Below in conjunction with description of drawings embodiment of the present utility model.
As shown in Figure 2, the utility model discloses a kind of pressure switch that is directly exposed under the external environment condition that is applicable to, pressure switch 7 comprises shell 77, on the two ends of shell 77, be respectively equipped with junction 71 and electronic plug 1, the compression spring 73 that in the inner chamber of shell 77, be provided with the plunger 72 that is connected with junction 71, the contact disc 74 that is connected with plunger 72 successively, is connected with contact disc 74, and with compress the adjusting double-screw bolt 76 that spring 73 is connected.The two ends of the inner chamber of shell 77 are provided with pipeline.Plunger 72 is arranged on the same end of junction 71, and string is located in the pipeline of this side, along endwisely slipping of shell 77.Regulate the same end that double-screw bolt 76 is arranged on electronic plug 1, string is located in the pipeline of this side, along endwisely slipping of shell 77.Position at the close internal chamber wall of shell 77 inner chambers is provided with sheet metal, is provided with some contacts 75 at sheet metal near on the end of contact disc 74, and this contact 75 is towards regulating double-screw bolt 76 1 ends.Contact disc 74 is clipped between contact 75 and the compression spring 73, by the tension force that compresses spring 73 contact disc 74 is withstood on the contact 75.
If this pressure switch is the normally closed type pressure switch, pressure acts on plunger 72 by junction 71, if pressure is greater than compressing spring 73 pressures, plunger 72 promptly drives contact disc 74 motions, thereby open the circuit between contact disc 74 and the contact 75, trigger pressure switch.When pressure descends, when the degree of pressure decline is encircled greater than stagnating, contact disc 74 and contact 75 closures, pressure switch is closed.
If this pressure switch is a pressure switch open in usual, the effect of its contact 75 is opposite with above-mentioned normally closed type pressure switch.
Technical characterictic of the present utility model is, is provided with lock interface 11 on the sidewall of above-mentioned electronic plug 1, is fixed with lock-on connection 5 in this lock interface 11, also is arranged with lock nut 6 on lock-on connection 5.
As shown in Figure 3, lock-on connection 5 overall structures meet whole requirement of water joint that VDE0619/EN50262(is used for electric prospection), can carry out corresponding specification adjustment according to the line footpath thickness of wiring on the pressure switch.The middle part of this lock-on connection 5 is provided with retainer ring 53, and 53 radius of this retainer ring is greater than the external diameter at lock-on connection 5 other positions.At the two ends of lock-on connection 5, be the line of demarcation with retainer ring 53, be made as interface link 51 and claw type locking end 52 respectively.This interface link 51 is provided with connecting thread, in the internal diameter of lock interface 11, also be provided with simultaneously connecting thread, connecting thread in connecting thread on this interface link 51 and lock interface 11 internal diameters is suitable, and the external diameter of interface link 51 is also suitable with the internal diameter of lock interface 11, interface link 51 closely is fixed in the lock interface 11 by connecting thread, and lock-on connection 5 closely is fixed on the sidewall of electronic plug 1 by interface link 51.
Claw type locking end 52 is divided into two parts, is provided with connecting thread near an end of retainer ring 53, and be made as can be by the suitable claw part of distortion of external force in the outer end of claw type locking end 52.
Lock-on connection 5 axially on be provided with through hole, this through hole is used for string and establishes electric wire, sets up circuit between the electronic plug 1 that this electric wire is used for pressure switch and the external world and is connected.Distortion by above-mentioned claw part, the internal diameter of through hole on the scalable lock-on connection 5, locking and relieving electric wire are realized closely being connected and fixed between electric wire and the lock-on connection 5, prevent that external environment from damaging electronic plug 1 inside by the slit between lock-on connection 5 and the electric wire.
Lock nut 6 is set on the claw type locking end 52 of lock-on connection 5.The internal diameter of lock nut 6 is provided with connecting thread, and the connecting thread on this connecting thread and the above-mentioned claw type locking end 52 is suitable, and lock nut 6 can closely be fixed on the claw type locking end 52 by connecting thread.The internal diameter of lock nut 6 is held 52 external diameter less than claw type locking in the utility model simultaneously.As shown in Figure 4, on lock nut 6, also be provided with axial through hole 61, when lock nut 6 is set on the lock-on connection 5, the through hole 61 of lock nut 6 is corresponding with the lead to the hole site on the lock-on connection 5, and forming a passage, the electric wire that guarantees to be connected on the electronic plug 1 is connected with the circuit in the external world.
Because lock nut 6 internal diameters are provided with the external diameter of a screw thread part less than claw type locking end 52, when lock nut 6 is set on the lock-on connection 5, along with lock nut 6 precession on claw type locking end 52, claw type locking end 52 dewclaw subdivisions can be along with precession, be subjected to the external force extruding of lock nut 6 towards inside, thereby make the 52 dewclaw subdivision generation deformation of claw type locking end, regulate the minimum diameter of lock-on connection 5, realization lock-on connection 5 is closely clamped electric wire, protection pressure switch inside suffers damage, when lock nut 6 precessions to retainer ring 53, retainer ring 53 stops that lock nut 6 continues precessions, lock-on connection 5 reaches the largest deformation state.Equally, along with lock nut 6 outwards screws out, the external force that is subjected on the claw type locking end 52 dewclaw subdivisions reduces, and returns to the original form gradually, loosens electric wire, is convenient to change or repair wires.
Because the deformation range of claw type locking end 52 has restriction on the lock-on connection 5, for guaranteeing lock-on connection 5 and lock nut 6 locking electric wires, lock nut 6 of the present utility model can directly be adjusted the specification size according to different electric wire lines with lock-on connection 5.
Although content of the present utility model has been done detailed introduction by above preferred embodiment, will be appreciated that above-mentioned description should not be considered to restriction of the present utility model.After those skilled in the art have read foregoing, for multiple modification of the present utility model with to substitute all will be conspicuous.Therefore, protection range of the present utility model should be limited to the appended claims.
