Abstract
The utility model relates to a multi-contact electromagnetic relay for power use, the external dimension of which is 59*23.5*40 mm. The multi-contact electromagnetic relay for power use is mainly used as a magnetic system composed of a pushing sheet, yoke iron, a coil, an iron core, an armature, and a restoration spring. A reed group with two clamping hooks and seven reed groups without the clamping hooks can form a contact system which is provided with eight auxiliary contacts and can form a miniature shell body composed of an external cover and a side plate which is provided with a bayonet base. The multi-contact electromagnetic relay for power use can be used for occasions, such as a relay protecting device of a power system, a safe and automatic device, a monitoring device, etc. The utility model well solves the unstable problem of the operating parameter of the relay when the original and homogeneous miniature relay is subjected to larger exogenic actions in a market.
Description
The utility model relates to a kind of electric power multiconductor electromagnetic relay.
Known electric power is the relay that DZ-619, the JZX-39F etc. of 48 * 23.5 * 40mm have 4 pairs of contacts with electromagnetic relay such as overall dimension, all links into an integrated entity with the yoke of one piece of long spiro nail with the band screw of contact system, base and magnetic system.Because this connection belongs to single-ended cantilever fixed form, when relay is subjected to doing the time spent than great machinery external force, it is the deflection displacement of fulcrum that the contact system that is in single-ended cantilever position can produce with the yoke screw, wherein free end is that the displacement of contact system outermost end is maximum, and observed maximum shift reaches more than the 0.7mm in the test.The relay contact group number of this project organization is many more, and cantilever is long more, and actuating of relay parameter that this displacement causes changes just obvious more, and is serious even can cause the actuating of relay to lose efficacy.
In view of the deficiency of above-mentioned prior art, the purpose of this utility model provides a kind of being subjected to and does the time spent than big external force, and the contact system displacement is restricted the comparatively stable electric power of action parameter multiconductor electromagnetic relay.
Solution of the present utility model is: a kind of electric power electromagnetic relay of forming by contact system, magnetic system and compact shell, and wherein magnetic system is made up of yoke, iron core, back-moving spring and coil that pushing piece, armature, band connect screw; Compact shell is made up of outer cover and side plate base with bayonet; Contact system has the contact by some upper end rivetings, and centre is the integral insulation pad, and there is the dynamic and static reed group of exit the lower end, and the reed group that is positioned at the contact system outermost end solid shim bottom of insulating has two grabs and forms.When it is characterized in that the relay assembling, when fusing by screw, contact system and base, magnetic system also two grabs of contact system outermost end reed group are stuck in two bayonet sockets of base side plate, do the time spent when relay is subjected to big external force, the displacement of contact system is restricted.
In profile was of a size of the housing of 59 * 23.5 * 40mm, the contact sets number reached eight pairs to the utility model electric power with the multiconductor electromagnetic relay.Owing to adopted the reed group and the side plate base with bayonet of band grab, be subjected to doing the time spent than big external force, action parameter is still very stable, satisfies the relay product specification requirement fully.
Below in conjunction with accompanying drawing and specific embodiment the utility model is described in detail.
Fig. 1, Fig. 2 are the structural representation of the utility model embodiment.
As shown in Figure 1 and Figure 2, the utility model electric power is made up of contact system, magnetic system and compact shell with the multiconductor electromagnetic relay, and wherein magnetic system is made up of yoke (10), coil (11), iron core (13), armature (14), the back-moving spring (15) of pushing piece (9), band screw; Compact shell is made up of the base (16) of outer cover (12) and side plate band bayonet socket (1); Contact system is not formed with the dynamic and static reed group (5) of grab with the static contact spring piece group (4) of two grabs (2) and seven by one.Contact system and base (16) and magnetic system fuse by screw (3), and two grabs (2) of static contact spring piece group (4) are stuck in two bayonet sockets (1) of base (16) simultaneously.This moment, the free gap of grab (2) in bayonet socket (1) was exactly that relay is subjected to external force and does the time spent, the issuable maximum shift of contact system.Debug and add outer cover (12) after qualified.Present embodiment middle shell overall dimension is 59 * 23.5 * 40mm, and the contact sets number is eight pairs, and the free gap of grab (2) in bayonet socket is limited in about 0.2mm.If cancellation two grabs are done the time spent in big external force, the free end maximum shift of contact system can reach 1～2mm.
Claims (1)
- A kind of by contact system, the electric power multiconductor electromagnetic relay that magnetic system and compact shell are formed, wherein magnetic system is by pushing piece (9), the yoke (10) of band screw, coil (11), iron core (13), armature (14), reset reed (15) is formed, compact shell is made up of the base (16) of outer cover (12) and side plate band breach (1), contact system is not made up of with the reed group (5) of grab the reed group (4) of a band grab (2) and seven, use screw (3) with contact system and base (16) when it is characterized in that the relay assembling, when magnetic system fuses, also two grabs (2) with the reed group (4) of contact system outermost end are stuck in two bayonet sockets (1) of base (16), and the displacement that makes contact system be subjected to external force to do the time spent is restricted.
