Description

The present invention relates to a relay structure and is an application of technology in the electric and electronic domain.

When the coil and contacts are energized in a relay, heat is generated due to Joule loss. The coil temperature of a general relay does not exceed 120 ° C., but if a situation such as an abnormally high temperature, a strange odor, or smoke occurs, an overvoltage is applied. If the switch is often loaded by arc discharge, the temperature will rise abnormally within a short time due to the arc heat.

However, most of the above-mentioned abnormalities are the generation of heat energy under abnormal conditions, and what should be considered here is the normal heat generation state in the operation of the relay, and generally the internal coil is in operation. Basically, it produces electromagnetic waves, and under the scientific principle of heat generated, there is a small amount of heat energy inside the relay, but when an electronic component such as a relay generates heat energy, it temporarily stays in the relay. Affects the overall normal operation. Of these, the most susceptible is the middle spring piece located inside the relay, which is the member that opens and closes inside the relay. One end of the middle spring piece makes contact and release by magnetic adsorption with the pin, but when the temperature of the middle spring piece overheats, heat energy is magnetically attracted and then transmitted to the circuit board via the pin, and the circuit board Affects driving.
In addition, overheating of the middle spring piece further affects the load current, disturbs the electron configuration in the current, and finally the above-mentioned situation occurs.

It is a main object of the present invention to effectively lower the temperature generated in the middle spring piece in the operation of the relay, increase the load current of the middle spring piece, and operate the entire relay normally.

In addition, a first support leg and a second support leg are installed and electrically connected to both ends of the electromagnetic member, and a part of them protrudes to the outside of the base body.
The magnetic guide member is installed inside the base body and is located around the electromagnetic member. One end of the magnetic guide member is electrically connected to one end of the electromagnetic member under normal conditions, and another end of the magnetic guide member magnetically attracts and presses the other end of the electromagnetic member when the electromagnetic member generates electromagnetic force. Install the braking piece and assemble it on the top surface of the magnetic guide member.
The spring unit is installed inside the base body and electrically connected to one end of the third support leg, and the other end of the third support leg extends out of the base body and protrudes. Further, the spring unit further includes a plurality of conducting pieces, and a part of each conducting piece is laminated and abuts, and a part is laminated and does not abut. In addition, one end of the spring unit is joined with a third support leg, and the side extending in the braking one direction of the other end is provided with a conductive connection member.

One end of the fourth support leg is installed at another end inside the base body and is exposed from the outside of the base body. Further, a contact member is provided on the side corresponding to the upper side of the conductive connection member at one end located in the base body of the fourth support leg.

In the present invention, the conductive area of the spring unit is increased by stacking and installing a large number of conductive pieces, and the load current is obviously increased due to the increase in the conductive area.

Further, a contact member 91 is provided at a position corresponding to the upper part of the conductive connection member 72 at one end located in the base body 1 of the fourth support leg 9.
By installing a plurality of conducting pieces 71 in the spring unit 7, when the spring unit 7 generates electromagnetics with the electromagnetic member 2, the spring unit 7 contacts one end of the conductive connecting member 72 by the magnetic attraction action of the magnetic conducting member 5. Energization is completed by contacting the member 91, and the conductive load area is increased by installing a plurality of conductive pieces 71, the temperature is effectively lowered, and the load current is improved.

As described above, the installation of the spring unit 7 increases the conductive load area, and the conductive load area is increased depending on the portion where the conductive pieces 71 are laminated but not joined. The amount of heat generated by the electromagnetic member 2 is applied to and dispersed in the spring unit 7, and the spring unit 7 is not kept at a high temperature.

The areas and stages described above do not abut against each other and form a gap 716 of the conducting pieces. Due to the formation of the gap 716 of the conducting pieces, the area of the spring unit 7 includes the arch portion 712 of each conducting piece 71, each surface of the second area 713, each surface of the inclined portion 714 and the third area 715, and is loaded by them. In addition to improving the current, the amount of heat of each conducting piece 71 is quickly and effectively released through the gap 716 of the conducting pieces, the temperature of each conducting piece 71 is effectively lowered, and the normality of the current conduction of the spring unit 7 is maintained. , Not affected by operational problems due to the influence of heat. The above is shown in FIGS. 4, 4A, and 2.

The detailed features of the present invention are as follows. First, the electromagnetic member 2 that generates electric power will be described. The electromagnetic member 2 includes two frames 21 and a coil 22. The two frames 21 are installed at both ends of the coil 22, and of the two frames 21, the frame 21 that magnetically attracts and contacts the magnetic guiding member 5 is further provided with a magnet contact point 211 to provide a magnet contact point 211. Is electrically connected to the coil 22.
Further, the bottom end of each frame 21 is provided with an insertion groove 212, and one ends of the first support leg 3 and the second support leg 4 are inserted and installed in the insertion groove 212 of each frame 21. One end of each of the first support leg 3 and the second support leg 4 is a base in order to insert the horizontal end of the first support leg 3 and the second support leg 4 directly into each insertion groove 212 for easy installation. It is used as a pin that is exposed from the body 1 and inserted into the circuit board. Further, the installation of each insertion groove 212 prevents the first support leg 3 and the second support leg 4 from loosening and affecting the conduction of the circuit. The above is shown in FIGS. 2 and 3.
The magnetic guiding member 5 described on the front surface includes a fixed magnet 51 and a movable magnet 52. One end of the fixed magnet 51 is installed in a frame 21 having no magnet contact point 211 in the two frames 21 and electrically connected to the coil 22. Further, another end of the fixed magnet 51 extends in the direction of the conductive connection member 72, then straddles the coil 22 again, abuts on the uppermost end of another frame 21, and further avoids the one end of the fixed magnet 51 that hits the above-mentioned frame 21. A notch 511 for the purpose is recessed.
Subsequently, the above-mentioned movable magnet 52 is assembled in the notch 511 for avoiding the fixed magnet 51, and the movable magnet 52 is prevented from moving after the operation. Further, when the coil 22 generates electromagnetism, one end of the movable magnet 52 is magnetically attracted to and contacts the magnet contact point 211. Further, another end of the movable magnet 52 bends through the notch 511 for avoidance and extends along the direction of the fixed magnet 51. The movable magnet 52 is joined to the fixed magnet 51 simply by inserting it into the portion of the notch 511 for avoidance. In this way, the movable magnet 52 operates in the base body 1 like a seesaw, and when the movable magnet 52 moves, it pushes the braking piece 6 and operates together. In the spring unit 7, when the braking piece 6 moves up and down, the conductive connecting member 72 is electrically connected to and separated from the contact member 91. The above is as shown in FIGS. 2, 7, 8 and 9.

When the movable magnet 52 operates by magnetic attraction, the braking piece 6 is moved upward, the conductive connection member 72 of the spring unit 7 is electrically connected to the contact member 91, and then the electromagnetic member 2 stops generating electricity, the movable magnet 52 And the magnet contact point 211 are released from contact with each other. In order to ensure the separation between the conductive connection member 72 and the contact member 91 and to prevent the magnetic attraction from remaining and maintaining the energized state, a return spring member 10 is provided inside the base body 1, and the return spring member 10 is elastic with the localization substrate 101. Includes substrate 102. The localization substrate 101 is installed inside the base body 1 and is interposed between the spring unit 7 and the movable magnet 52. In addition, one end of the elastic substrate 102 is connected to the localization substrate 101. Another end of the elastic substrate 102 is recessed downward to press the movable magnet 52. When the elastic substrate 102 electromagnetically contacts the magnet contact point 211 with one end of the movable magnet 52, it is pressed and slightly elastically deformed. These prevent the movable magnet 52 from affecting the energization due to excessive movement. The above is as shown in FIGS. 2, 8 and 9.

In order to prevent the movable magnet 52 from colliding with the fixed magnet 51 in the process of repetitive operation, a localization groove 512 is recessed on one side of the fixed magnet 51 and at a position corresponding to the braking piece 6, and the movable magnet is movable. A localization cutout 521 is provided at a position corresponding to the localization groove 512 of 52, and the localization cutout 521 communicates with the localization groove 512. Further, a part of the bottom end of the braking piece 6 is convexly formed with an interlocking convex 61, and the interlocking convex 61 passes through the localization notch 521 and is pressed by the bottom of the localization groove 512. Further, one end, that is, a part of the interlocking convex 61 of the braking piece 6 presses the movable magnet 52. Since the fixed magnet 51 does not move, the movable magnet 52 reliably moves the braking piece 6 up and down in the operation process. Further, when the braking piece 6 moves downward, the interlocking convex 61 is inserted into the localization groove 512, the position is restricted and the brake piece 6 cannot be easily disengaged, and the overall operation is maintained.
In the above description, in addition to the localization groove 512 limiting the repositioning position of the braking piece 6, the holding convex 522 is installed on the uppermost surface of the movable magnet 52 and on both sides where the braking piece 6 is located. The braking piece 6 is sandwiched between the two sandwiching protrusions 522, thereby preventing the braking piece 6 from being distorted in the process of position movement.
In addition, a perforation 513 is bored in a position close to the localization groove 512 of the fixed magnet 51, and the cushioning member 20 is assembled in the perforation 513. When the movable magnet 52 is not in electromagnetic contact with the magnet contact point 211, the movable magnet 52 is normally in contact with the cushioning member 20 to prevent the movable magnet 52 from colliding with the fixed magnet 51 during the repositioning operation, and is movable. The relationship between the magnet 52 and the fixed magnet 51 is maintained. The above is as shown in FIGS. 2, 8 and 9.

Finally, the base body 1 further includes the outer housing 11 and the main body 12. The inside of the main body 12 forms an assembly space 13 with a space. In addition, the localization space 14 is further partitioned into the assembly space 13, the localization substrate 101 of the return spring member 10 is fixed in the localization space 14, and the outer housing 11 is in the electromagnetic member 2, the magnetic guide member 5, and the spring unit 7.
