Description

Technical Field

[0001] The utility model belongs to the technical field of relays, and in particular relates to a ceramic relay which is easy to disassemble and assemble. Background Art

[0002] High temperature resistant relays are mainly made of ceramic materials, which have the advantages of high temperature resistance, corrosion resistance, vibration resistance, etc., and are widely used in control systems. Ceramic materials have a high melting point and high temperature resistance, so that they can work in high temperature environments without leakage or burning due to temperature increases. At the same time, ceramic materials also have good corrosion resistance, which can resist the erosion of corrosive media such as acids and alkalis, and extend the service life of relays.

[0003] However, the base and shell inside the existing ceramic relay are fixed by a simple clip-on structure, and the fixing strength between the two is not high. This is to make it more convenient to unplug the shell for maintenance. However, due to the low fixing strength between the two, when the relay is installed on some mobile equipment such as a car, the relay shell may fall off due to the vibration as the car is bumpy during driving. At the same time, since the shell almost completely covers the base, there is less part of the relay base remaining outside. When the maintenance personnel need to unplug the ceramic relay, it is possible that only the relay shell is unplugged without unplugging the base. Utility Model Content

[0004] In view of the shortcomings of the prior art, the purpose of the present invention is to provide a new ceramic relay to solve the problems mentioned in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a ceramic relay that is easy to disassemble and assemble, comprising a ceramic relay base, a relay housing is provided above the ceramic relay base, and a highly convenient and stable connecting mechanism is provided on both sides of the lower end surface of the relay housing, and the relay housing is connected to the ceramic relay base through the highly convenient and stable connecting mechanism, and the highly convenient and stable connecting mechanism comprises a connecting and fixing port, a connecting head, a pushing column and a fixed transmission mechanism, the connecting and fixing port is located on the upper end surface of the ceramic relay base, and the connecting head is fixed to the lower end surface of the relay housing, and in the process of inserting the connecting head into the connecting and fixing port, the ceramic relay base and the relay housing can be fixed by the fixed transmission mechanism, and when the pushing column is pushed inward, the connecting head can be pushed upward by the synchronization mechanism.

[0006] Further preferably, the lower end surface of the connector is connected to a spring, and the lower end surface of the spring is connected to a metal hook fixed to the ceramic relay base.

[0007] Further preferably, the fixed transmission mechanism comprises a strip groove, a fixing spring is provided inside the strip groove, one side of the fixing spring is connected to a rectangular fixing head located outside the connecting head, and the lower end surface of the rectangular fixing head is an inclined surface.

[0008] Further preferably, a fixing opening connected to the inner wall of the fixing opening is provided on the outer side of the rectangular fixing head, and the upper end surface of the rectangular fixing head is in contact with the inner wall of the fixing opening.

[0009] Further preferably, a cylindrical groove is provided on one side of the fixing port, which is located inside the ceramic relay base and communicated with the interior of the fixing port; a limiting sleeve is provided inside the cylindrical groove and fits with the inner wall thereof; the pushing column is connected to the axis of the limiting sleeve, and the position of the pushing column corresponds to the position of the rectangular fixing head.

[0010] Further preferably, a return spring is provided at the upper and lower parts of the pushing column, and the two ends of the return spring are respectively connected to the inner wall of the cylindrical groove and the limiting sleeve.

[0011] Further preferably, the top end of the pushing column extends to the outside of the ceramic relay base by penetrating the ceramic relay base, and the pushing column is movably connected to the ceramic relay base.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] (1) The utility model effectively fixes the ceramic relay base and the housing through a highly convenient and stable connection mechanism. Specifically, when the base and the housing need to be fixed, it is only necessary to align the connecting head fixed on the lower end face of the relay housing with the connecting and fixing port located on the upper end face of the ceramic relay base, and then insert it so that the rectangular fixing head located on the outer surface of the connecting head is inserted into the fixing port located on the inner wall of the connecting and fixing port, thereby fixing the base and the housing. Since the ceramic relay base and the relay housing are fixed by inserting the rectangular fixing head into the inside of the fixing port, as long as a part of the rectangular fixing head is still located inside the fixing port, the ceramic relay base and the relay housing cannot be separated. The above technical solution can improve the fixing strength between the ceramic relay base and the relay housing, thereby preventing the relay housing from being separated from the base due to vibration or external pulling.

[0014] (2) The utility model compresses the spring when the connecting head penetrates into the interior of the connecting fixing port. When the fixing between the ceramic relay base and the housing needs to be released, the rectangular fixing head is pushed inward by the pushing column. When the rectangular fixing head completely leaves the interior of the fixing port, the reaction force of the squeezed spring can move the connecting head and the relay housing fixed to the upper end face of the connecting head upward, thereby releasing the fixation of the relay housing, thereby retaining the convenience of disassembling and assembling the relay housing.

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] The relay base 1 (model NVR6V-20), the return spring 12 (model JX110) and the metal hook 14 (model 304) used in the utility model can be purchased from the market.

[0022] See also Figures 1 to 4The utility model provides an embodiment: a ceramic relay that is easy to disassemble and assemble, including a ceramic relay base 1, a relay housing 2 is provided above the ceramic relay base 1, and a highly convenient and stable connecting mechanism is provided on both sides of the lower end surface of the relay housing 2. The relay housing 2 is connected to the ceramic relay base 1 through the stable connecting mechanism. The stable connecting mechanism includes a connecting and fixing port 3, a connecting head 4, a pushing column 13 and a fixed transmission mechanism. The connecting and fixing port 3 is located on the upper end surface of the ceramic relay base 1, and the connecting head 4 is fixed to the lower end surface of the relay housing 2. In the process of inserting the connecting head 4 into the connecting and fixing port 3, the ceramic relay base 1 and the relay housing 2 can be fixed by the fixed transmission mechanism, and when the pushing column 13 is pushed inward, the connecting head 4 can be pushed upward by the synchronization mechanism.

[0023] The fixed transmission mechanism includes a strip groove 6, inside of which a fixing spring 8 is provided, and one side of the fixing spring 8 is connected to a rectangular fixing head 7 located outside the connecting head 4, and the lower end face of the rectangular fixing head 7 is an inclined surface; when it is necessary to fix the ceramic relay base 1 and the relay housing 2, pick up the relay housing 2 and align the connecting head 4 fixed on the lower end face of the relay housing 2 with the entrance of the connecting fixing port 3, and push the connecting head 4 downward, as the connecting head 4 goes deeper, the rectangular fixing head 7 located on its outer surface will contact the entrance of the connecting fixing port 3, and through the inclined surface of its lower end face, as the rectangular fixing head 7 descends, the rectangular fixing head 7 will be pushed inward and squeeze the fixing spring 8.

[0024] The outer side of the rectangular fixing head 7 is provided with a fixing opening 9 located on the inner wall of the connecting fixing opening 3, and the upper end surface of the rectangular fixing head 7 is in contact with the inner wall of the fixing opening 9; when the rectangular fixing head 7 that squeezes the fixing spring 8 moves to the position of the fixing opening 9 located on the inner wall of the connecting fixing opening 3, the rectangular fixing head 7 is pushed outward by the reaction force of the squeezed fixing spring 8, so that it is stuck in the inside of the fixing opening 9, thereby achieving effective fixation between the ceramic relay base 1 and the relay housing 2. Since the ceramic relay base 1 and the relay housing 2 are fixed by inserting the rectangular fixing head 7 into the inside of the fixing opening 9, as long as a part of the rectangular fixing head 7 is still located in the inside of the fixing opening 9, the ceramic relay base 1 and the relay housing 2 cannot be separated. The above technical solution can improve the fixing strength between the ceramic relay base 1 and the relay housing 2, thereby preventing the relay housing 2 from leaving the ceramic relay base 1 due to vibration or external pulling.

[0025] The lower end surface of the connector 4 is connected to a spring 5, and the lower end surface of the spring 5 is connected to a metal hook 14 fixed to the ceramic relay base 1; the connector 4 will contact the spring 5 in the process of penetrating into the connection fixing port 3, and as the connector 4 descends, the spring 5 will be gradually squeezed, and the metal hook 14 connected to the lower end surface of the spring 5 can prevent the spring 5 from falling out of the connection fixing port 3.

[0026] A cylindrical groove 10 located inside the ceramic relay base 1 and communicating with the inside of the fixing mouth 9 is provided on one side of the fixing mouth 9. A limiting sleeve 11 is provided inside the cylindrical groove 10 and fits with the inner wall thereof. A push post 13 is connected to the axis of the limiting sleeve 11, and the position of the push post 13 corresponds to the position of the rectangular fixing head 7. A reset spring 12 is provided above and below the push post 13. The two ends of the reset spring 12 are respectively connected to the inner wall of the cylindrical groove 10 and the limiting sleeve 11. The top end of the push post 13 extends to the bottom of the ceramic relay by penetrating the ceramic relay base 1. The outer side of the base 1 is connected to the ceramic relay base 1, and the push column 13 is movably connected to the ceramic relay base 1; when the ceramic relay base 1 and the relay housing 2 need to be released, the push column 13 can be pushed inward. As the push column 13 moves, the push column 13 will contact the rectangular fixing head 7 and push the rectangular fixing head 7 inward. When the rectangular fixing head 7 completely enters the interior of the strip groove 6, the reaction force of the squeezed spring 5 can make the connector 4 and the relay housing 2 fixed to the upper end surface of the connector 4 move upward, thereby releasing the fixation of the relay housing 2. The above technical solution retains the convenience of disassembling and assembling the relay housing 2, and prevents the operation from being complicated due to the setting of the fixing mechanism.

[0027] When the push post 13 is pushed forward, the limit sleeve 11 fixed with it will move together and squeeze the reset spring 12. When the fixation between the ceramic relay base 1 and the relay housing 2 is released, the push post 13 is released, and then the reaction force of the squeezed reset spring 12 can return the limit sleeve 11 and the push post 13 to their original positions.

[0028] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.
