Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of relays, and more specifically, to a relay coil frame. Background Art
[0002] A relay is an electrical component commonly used in automatic control, and its main structure is a coil frame and a housing. When the existing coil frame is in use, the coil on the coil frame is energized to magnetize the iron core inside the coil, thereby generating a large magnetic force, which in turn attracts the swing contact to swing in the corresponding direction, thereby achieving contact and connection on one side of the contact. When the coil is not energized, the attraction of the iron core to the swing contact disappears, and the spring at one end of the swing contact will be tightened under the action of its own elastic force, thereby pulling the swing contact to swing in the opposite direction, thereby achieving contact and connection on the other side of the contact, thereby achieving on-off control of the corresponding circuit.
[0003] It has been found during use that for coil frames in relatively harsh working environments, the springs of the coil frames are thin and not corrosion-resistant, and thus are easily rusted and broken due to the humid environment, causing the swing contacts to lose their spring action and swing at will, affecting the normal use of the relay and resulting in poor practicality.

[0010] The utility model is further configured that the outer ends of the two sets of sliding sleeves are both provided with heat insulating sleeves, and the setting of the heat insulating sleeves can effectively block the heat generated by the coil being energized, thereby preventing the circular magnets 1 and 2 from being heated and causing the magnetic force to disappear.
[0011] The utility model is further configured such that the inner bottom ends of the two sets of sliding sleeves are both provided with heat insulation pads, and the provision of the heat insulation pads can effectively prevent the base from transferring heat to the circular magnets one and two, thereby improving the magnetic stability of the circular magnets one and two.

[0013] The utility model is further configured that the right end of the slide groove at the right end of the base is provided with a chamfer, and the setting of the chamfer can make it easier to slide the slider into the slide groove.

[0015] (III) Beneficial effects
[0016] Compared with the prior art, the utility model provides a relay coil frame, which has the following beneficial effects:
[0017] 1. On-off structure design. When using the relay coil frame, when the upper contact 1 and contact 2 need to be in contact, the coil is in a non-energized state. At this time, the two sets of sliding bars will be lifted under the mutual repulsion of the same poles of the two sets of circular magnets 1 and 2, thereby driving the cross bar to rise until the contact 1 at the top of the cross bar contacts the contact 2, and the relay as a whole is in a disconnected state; when the lower contact 1 and contact 3 need to contact, the coil can be energized. At this time, the coil generates magnetic force, because the suction force of the coil on the cross bar is greater than the repulsion of the two sets of circular magnets 1 and 2, thereby attracting the cross bar to descend until the contact 1 at the lower end of the cross bar contacts the contact 3, and the relay is in a connected state; through this device, the on-off function of the relay can be realized more efficiently, and the overall parts have no easily corrosive components. Only the two sets of circular magnets 1 and 2 are used to replace the spring to perform the reset action, so that the relay works more stably and is suitable for on-off control work in a humid environment.
[0018] 2. Coil design. When installing the coil frame, the slider at the bottom of the coil can be directly slid into the slide groove. When the coil is in use, the existing coils use glue to fix the iron core inside the frame. This causes the frequent on and off of the coil to easily cause the glue to loosen, thereby reducing the on-off control accuracy of the relay. Therefore, the coil frame is improved. The iron core needs to be slid into the frame from the bottom, and a rib smaller than the outer diameter of the iron core is provided at the top of the frame, thereby effectively preventing the iron core from loosening during the operation of the coil. Through this device, the coil frame can be installed and the iron core can be fixed in position more efficiently, further improving the working stability of the relay.
[0019] 3. The limit mechanism is designed. When the slide bar and the sleeve slide relative to each other, the two sets of limit bars will slide relative to each other in the two sets of limit grooves, thereby limiting the positions of the two sets of slide bars at the highest and lowest positions, thereby ensuring that the horizontal bar can be lifted and lowered horizontally when the two sets of contacts 1 are in contact with contacts 2 and 3 respectively, avoiding the tilting of the left and right sides of the horizontal bar and the jamming between the slide bar and the sleeve due to excessive repulsion between the two sets of circular magnets 1 and 2 or excessive suction of the coil, thereby further improving the working stability of the relay.

DETAILED DESCRIPTION

The present utility model will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.
[0027] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meanings as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0029] See also Figure 1-5 A relay coil frame comprises a base 1, a switch structure is arranged at the top of the base 1, and the switch structure comprises a coil 2, which is installed at the top of the base 1, and a sliding sleeve 3 is arranged on both the front and rear sides of the top of the base 1, and sliding rods 4 are slidably arranged in the two groups of sliding sleeves 3, and circular magnets 1 5 and circular magnets 2 6 are arranged at the bottom ends of the two groups of sliding sleeves 3 and the bottom ends of the two groups of sliding rods 4 respectively, and the two groups of circular magnets 2 6 on the upper side are placed with the same poles as the two groups of circular magnets 1 5 on the lower side, and a cross bar 7 is arranged at the inner ends of the two groups of sliding rods 4, and a contact 1 8 is arranged on the upper and lower sides of the left end of the cross bar 7, a side plate 9 is arranged on the left side of the top of the base 1, and a contact 2 10 and a contact 3 11 are arranged on the right side of the side plate 9, and the sliding sleeve 3 is provided with a limiting mechanism.
[0030] In this embodiment, when the relay coil frame is used, when the upper contact 1 8 and contact 2 10 need to be in contact, the coil 2 is in an unpowered state. At this time, the two groups of slide bars 4 will be lifted under the mutual repulsion of the same poles of the two groups of circular magnets 1 5 and the two groups of circular magnets 2 6, thereby driving the cross bar 7 to rise until the contact 1 8 at the top of the cross bar 7 contacts the contact 2 10, and the relay as a whole is in a disconnected state; when the lower contact 1 8 and contact 3 11 need to contact, the coil 2 can be energized, and the coil 2 generates magnetic force, because the suction force of the coil 2 on the cross bar 7 is greater than the repulsion of the two groups of circular magnets 1 5 and the two groups of circular magnets 2 6, thereby attracting the cross bar 7 to descend, until the contact 1 8 at the lower end of the cross bar 7 contacts the contact 3 11, and the relay is in a connected state.
[0031] More specifically, during the operation of the coil frame, the thermal insulation sleeve 16 can effectively block the heat generated by the coil 2 when it is energized, and the setting of the thermal insulation pad 17 can effectively prevent the base 1 from generating heat transfer to the circular magnet 1 5 and the circular magnet 2 6, thereby preventing the circular magnet 1 5 and the circular magnet 2 6 from being heated and causing the magnetic force to dissipate, thereby improving the magnetic stability of the circular magnet 1 5 and the circular magnet 2 6.
[0032] See also Figure 1 , Figure 3 and Figure 4 , as an implementation method for assembling the coil frame: when the coil 2 is installed on the coil frame, the slider 14 at the bottom end of the coil 2 can be directly slid into the slide groove. When the coil 2 is in use, the existing coil 2 uses glue to fix the iron core 13 inside the frame 12. This causes the frequent power on and off of the coil 2 to easily cause the glue to loosen, thereby reducing the on-off control accuracy of the relay. Therefore, the coil frame 12 is improved. The iron core 13 needs to be slid into the frame 12 from the bottom, and a rib smaller than the outer diameter of the iron core 13 is provided at the top of the frame 12, thereby effectively preventing the iron core 13 from loosening during the operation of the coil 2.
[0033] Specifically, when the slider 14 is slidably inserted into the slide groove, the chamfer 19 can make it easier to slide the slider 14 into the slide groove, further improving the convenience and efficiency of assembling the coil frame.
[0034] Please refer to Figure 4, as a further implementation method for the relative sliding of the slide bar 4 and the sleeve 3: when the slide bar 4 and the sleeve 3 slide relative to each other, the two groups of limit rods 15 will slide relative to each other in the two groups of limit grooves, thereby limiting the positions of the two groups of slide bars 4 at the highest and lowest positions, thereby ensuring that the cross bar 7 can be lifted and lowered horizontally when the two groups of contacts 1 8 are in contact with the contact 2 10 and the contact 3 11 respectively, avoiding the tilting of the left and right sides of the cross bar 7 and the jamming between the slide bar 4 and the sleeve 3 due to the excessive repulsive force between the two groups of circular magnets 1 5 and the two groups of circular magnets 2 6 or the excessive suction force of the coil 2, thereby further improving the working stability of the relay.
[0035] Specifically, during the relative sliding of the limit rod 15 and the limit groove, the roller 20 can effectively reduce the sliding friction between the limit rod 15 and the limit groove, thereby improving the smoothness and accuracy of the position movement of the limit rod 15, and further improving the working accuracy and stability of the relay.
[0036] To sum up, when the overall equipment is in use:
[0037] When the relay coil frame is in use and the upper contact 1 8 and contact 2 10 need to be in contact, the coil 2 is in an unpowered state. At this time, the two groups of slide bars 4 will be lifted under the mutual repulsion of the same poles of the two groups of circular magnets 1 5 and the two groups of circular magnets 2 6, thereby driving the cross bar 7 to rise until the contact 1 8 at the top of the cross bar 7 contacts the contact 2 10, and the relay as a whole is in a disconnected state; when the lower contact 1 8 and contact 3 11 need to contact, the coil 2 can be energized, and the coil 2 generates magnetic force, because the suction force of the coil 2 on the cross bar 7 is greater than the repulsion of the two groups of circular magnets 1 5 and the two groups of circular magnets 2 6, thereby attracting the cross bar 7 to descend, until the contact 1 8 at the lower end of the cross bar 7 contacts the contact 3 11, and the relay is in a connected state.
[0038] When installing the coil frame on the coil 2, the slider 14 at the bottom end of the coil 2 can be directly slid into the slide groove. When the coil 2 is in use, the existing coil 2 uses glue to fix the iron core 13 inside the frame 12. This causes the frequent power on and off of the coil 2 to easily cause the glue to loosen, thereby reducing the on-off control accuracy of the relay. Therefore, the coil frame 12 is improved. The iron core 13 needs to be slid into the frame 12 from the bottom, and a rib smaller than the outer diameter of the iron core 13 is provided at the top of the frame 12, thereby effectively preventing the iron core 13 from loosening during the operation of the coil 2.
[0039] When the slide bar 4 and the sleeve 3 slide relative to each other, the two groups of limit rods 15 will slide relative to each other in the two groups of limit grooves, thereby limiting the positions of the two groups of slide bars 4 at the highest and lowest positions, thereby ensuring that the cross bar 7 can be lifted and lowered horizontally when the two groups of contacts 1 8 are in contact with the contact 2 10 and the contact 3 11 respectively, avoiding the tilting of the left and right sides of the cross bar 7 and the jamming between the slide bar 4 and the sleeve 3 due to excessive repulsion between the two groups of circular magnets 1 5 and the two groups of circular magnets 2 6 or excessive suction of the coil 2, thereby further improving the working stability of the relay.

In the above, all fixed connections are preferably welded.
