Abstract
The utility model discloses a relay which comprises a base (1), a yoke iron (2) and a coil. The yoke iron (2) is fixed on the base (1), the coil is fixed on the yoke iron (2), and a barrel-shaped insulating sleeve (3) is sheathed outside the coil. Both the stability of the voltage enduring effect of the relay are ideal.
Description
Technical field
The utility model relates to a kind of electronic control device, specifically is a kind of relay.
Background technology
Relay is the electronic control device that plays effects such as automatic adjusting, safeguard protection and change-over circuit in circuit.Its operation principle is as follows: when the function of current of input circuit produces electromagnetic induction during in relay coil, make armature under electromagnetic field effect, overcome spring tension and move to coil direction, thereby the moving contact on the drive armature with often open the fixed contact adhesive, when the current vanishes of input circuit, make magnetic field diminishes, armature resets, thereby the drive moving contact resets to the position with normally closed fixed contact adhesive, like this, by the change of input circuit electric current, realize the conducting and the cut-out of output loop.So relay is the automatic switch of regulating and control big electric current with little electric current in essence.
The relay of prior art comprises pedestal, yoke and coil, and described yoke is fixed on the pedestal, and described coil stationary is on yoke, and described coil is wound with insulating tape outward.There is following defective in the relay of prior art: be adjacent on coil because insulating tape twines, and the high temperature that the contact arcing produces during high capacity can make adhesive plaster produce harmful substance, harmful substance can be diffused in the conducting that influences output loop on the contact, so relay work is stable undesirable; Because insulating tape thickness is less, so the voltage that can carry is less, promptly resistance to pressure is undesirable again.
The utility model content
The technical problems to be solved in the utility model is that a kind of stability and all desirable relay of withstand voltage effect are provided.
Technical solution of the present utility model is, a kind of relay with following structure is provided, and it comprises pedestal, yoke and coil, and described yoke is fixed on the pedestal, described coil stationary is on yoke, and described coil is sheathed with the insulating case of a tubular outward.
After adopting above structure, the utility model relay compared with prior art has the following advantages:
Have certain effect of heat insulation owing to be linked in the outer insulating case of coil, the high temperature that the contact arcing produces when having avoided high capacity is to the harmful effect of adhesive plaster, so the relay job stability is better; Again since the thickness of insulating case greater than the thickness of insulating tape, so the voltage that can carry is bigger, i.e. resistance to pressure better (compressive resistance between its coil and the yoke can reach 360V).
Description of drawings
Fig. 1 is the structural representation of the utility model relay.
Fig. 2 is the structural representation of the insulating case of the utility model relay.
Shown in the figure 1, pedestal, 2, yoke, 3, insulating case, 4, case.
Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
As shown in Figure 1 and Figure 2, the utility model relay, it comprises pedestal 1, yoke 2, coil and case 4, and described yoke 2 is fixed on the pedestal 1, and described coil stationary is on yoke 2, and described coil is sheathed with the insulating case 3 of a tubular outward.Described insulating case 3 preferred plastic insulation coverings 3.The upper end open of described insulating case 3, this insulating case 3 down is linked on the coil from the opening of upper end, and the base plate of described insulating case 3 is provided with the through hole that the iron core for coil passes.
Claims (1)
1. relay, it comprises pedestal (1), yoke (2) and coil, and described yoke (2) is fixed on the pedestal (1), and described coil stationary is characterized in that on yoke (2): described coil is sheathed with the insulating case (3) of a tubular outward.
