Description

[0002] The housing assembly of a relay usually includes a base and a shell. The main contact assembly, auxiliary contact assembly, electromagnetic assembly, armature and other components of the relay are usually arranged on the base.

[0038] In addition, if the terms "first" or "second" appear, these terms are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of the features. In the description of this application, if the term "plurality" appears, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0039] In this application, unless otherwise clearly specified and limited, if the terms "installed", "connected", "connected", "fixed" and the like appear, these terms should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integrated connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to the specific circumstances.

[0040] In the present application, unless otherwise clearly specified and limited, if there is a description that a first feature is "above" or "below" a second feature, etc., or similar descriptions appear, it may mean that the first and second features are in direct contact, or that the first and second features are in indirect contact through an intermediate medium. Moreover, the first feature being "above", "above" and "above" the second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. The first feature being "below", "below" and "below" the second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.

[0041] It should be noted that if an element is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be a central element.

If any, the terms "vertical", "horizontal", "upper", "lower", "left", "right" and similar expressions used in this application are for illustrative purposes only and do not represent the only implementation method.

[0042] In a traditional relay, the active spring part and the main static spring part of the main contact assembly, as well as the auxiliary active spring part and the auxiliary static spring part of the auxiliary contact assembly, are usually installed on the base, and the outer shell is installed on the base to provide protection for the components on the base. During the assembly process of the relay, the base and the outer shell usually need to be bonded together with plastic sealant. During the baking and curing process of the plastic sealant, the plastic sealant will shrink, which is easy to form a shrinkage pulling force on the base and cause the base to deform, thereby affecting the assembly accuracy of the components on the base, affecting the matching accuracy between the components and the connection accuracy between the components and the external circuit, thereby affecting the electrical performance of the relay.

[0043] In order to solve the above problems, the present application provides a housing assembly and a relay.

[0044] See also Figure 1-Figure 4 As shown, Figure 1 and Figure 3Schematic diagrams of the structure of the relay 10 at different angles in some embodiments, Figure 2 It is a schematic diagram of the structure of the relay 10 after omitting the housing 22 in some embodiments. Figure 4 for Figure 3 The schematic cross-sectional view of the relay 10 shown is taken along the AA direction. The relay 10 provided in the present application can be used to be connected to one or more external circuits and to control the on and off of one or more external circuits. In some embodiments, the relay 10 includes an electromagnetic assembly 11, a main contact assembly 12, an auxiliary contact assembly 13, an armature 14 and a housing assembly 20, the housing assembly 20 includes a base 21 and a shell 22, the electromagnetic assembly 11, the main contact assembly 12, the auxiliary contact assembly 13 and the armature 14 are all arranged on the base 21, and the shell 22 is covered on the base 21 to provide protection for the components on the base 21.

[0045] The electromagnetic assembly 11 may include a coil frame 111, a coil 112 sleeved on the coil frame 111, and an iron core 113 arranged in the coil 112. The main contact assembly 12 may include an active spring part 121 and a main static spring part 122 arranged on the base 21. The auxiliary contact assembly 13 may include an auxiliary active spring part 131 and an auxiliary static spring part 132 arranged on the base 21. When the coil 112 is energized or the current direction of the coil 112 changes, the electromagnetic force can be used to make the armature 14 move relative to the base 21, so that the armature 14 can drive the active spring part 121 to move toward or away from the main static spring part 122 through the push card or any other suitable transmission element, so that the active contact on the active spring part 121 contacts or separates with the main static contact on the main static spring part 122. The movement of the armature 14 relative to the base 21 can also drive the auxiliary movable spring part 131 to move toward or away from the auxiliary static spring part 132 through the transmission structure provided on the armature 14 or any other suitable transmission element, so that the auxiliary movable contact on the auxiliary movable spring part 131 contacts or separates with the auxiliary static contact on the auxiliary static spring part 132.

[0046] Combination Figure 5 and Figure 6As shown, in some embodiments, the base 21 includes a first side 213 and a second side 214 opposite to each other, and components such as the main contact assembly 12, the auxiliary contact assembly 13, the electromagnetic assembly 11, and the armature 14 are arranged on the first side 213 of the base 21. The housing 22 includes a side plate portion 222 and a cover plate portion 221. The side plate portion 222 is arranged around the base 21. The cover plate portion 221 is located on the first side 213 of the base 21 and is connected to the side plate portion 222 to enclose the side plate portion 222 to form an accommodating space for accommodating components on the base 21. The side plate portion 222 and the cover plate portion 221 can be an integrated structure. The active spring portion 121, the main static spring portion 122, the auxiliary active spring portion 131, and the auxiliary static spring portion 132 can partially penetrate the base 21 and extend to the second side 214 of the base 21 for communicating with an external circuit. The coil 112 can also be connected to the external circuit on the second side 214 through the pins penetrating the base 21. It should be noted that in the present application, the naming of the base 21 does not mean any limitation on the structure and setting position of the base 21. In the relay 10, the setting position of the base 21 is not limited. The base 21 includes but is not limited to a base structure, an upper shell structure or an outer shell structure.

[0047] Furthermore, combined with Figure 7 and Figure 8 As shown, in some embodiments, a glue dispensing groove 2221 is formed between the side plate portion 222 of the housing 22 and the base 21. During the assembly of the housing 22 and the base 21, any suitable glue such as plastic sealant can be arranged in the glue dispensing groove 2221 to adhere the housing 22 and the base 21. The base 21 is provided with a first partition groove 2121, and the first partition groove 2121 is located on the inner side of the glue dispensing groove 2221. The materials of the housing 22 and the base 21 involved in the present application include but are not limited to any suitable materials such as plastic.

[0048] In the above-mentioned shell assembly 20, the base 21 is provided with a first partition groove 2121 located on the inner side of the glue dispensing groove 2221. During the assembly process of the shell 22 and the base 21, when plastic sealant is provided in the glue dispensing groove 2221 to adhere the shell 22 and the base 21, during the baking and curing process of the plastic sealant, the plastic sealant will shrink and generate a shrinkage pulling force on the base 21. The provision of the first partition groove 2121 enables the portion of the base 21 located outside the first partition groove 2121 to absorb the shrinkage pulling force generated by the plastic sealant through flexible deformation, preventing the shrinkage pulling force from being transmitted to the inner side of the first partition groove 2121 and causing the portion of the base 21 located inside the first partition groove 2121 to deform, thereby affecting the assembly accuracy of the components on the base 21 on the base 21. Therefore, the above-mentioned shell assembly 20, by providing the first partition groove 2121, prevents the base 21 from deforming during the glue dispensing assembly process with the shell 22, which is conducive to improving the electrical performance of the assembled shell assembly 20.

[0049] Combination Figure 4 and Figure 8 As shown, in some embodiments, the base 21 includes a main body 211 and a peripheral portion 212, the peripheral portion 212 is arranged around the main body 211 in the circumferential direction and connected to the main body 211, the components of the relay 10 are arranged on the main body 211, the side plate 222 is arranged around the peripheral portion 212, the glue dispensing groove 2221 is formed between the peripheral portion 212 and the side plate 222, and the first partition groove 2121 is arranged on the peripheral portion 212. The glue dispensing groove 2221 can be arranged toward the second side 214, so as to facilitate glue dispensing in the glue dispensing groove 2221 after the base 21 and the shell 22 are assembled. For example, the outer periphery of the peripheral portion 212 can be provided with a notch, and when the shell 22 and the base 21 are assembled, the notch of the peripheral portion 212 forms the glue dispensing groove 2221. In the direction from the peripheral portion 212 to the side plate portion 222 , the first partition groove 2121 and the glue dispensing groove 2221 are sequentially arranged at intervals, so that the first partition groove 2121 can prevent the shrinkage pulling force generated by the plastic sealant from being transmitted to the main body 211 .

[0050] In some embodiments, the first partition groove 2121 is formed on the surface of the peripheral portion 212 facing the second side 214, that is, the first partition groove 2121 faces the second side 214. In this embodiment, the depth of the first partition groove 2121 is greater than the depth of the glue dispensing groove 2221. In the depth direction of the first partition groove 2121, at least part of the position of the first partition groove 2121 corresponds to the glue dispensing groove 2221, that is, the glue dispensing groove 2221 is located within the depth range of the first partition groove 2121 in the depth direction of the first partition groove 2121, so that the first partition groove 2121 can effectively block the contraction pulling force generated by the plastic sealant in the glue dispensing groove 2221 from being transmitted to the main body 211. In the present application, the depth directions of the first partition groove 2121 and the glue dispensing groove 2221 are both parallel to the direction from the first side 213 to the second side 214.

[0051] In other embodiments, the first partition groove 2121 may also be provided on the surface of the peripheral portion 212 facing the first side 213, that is, the first partition groove 2121 faces the first side 213. In this embodiment, the first partition groove 2121 and the glue dispensing groove 2221 may be staggered in the depth direction, or may have portions corresponding to each other in the depth direction. The first partition groove 2121 is provided on the surface of the peripheral portion 212 facing the first side 213, that is, inside the housing assembly 20, and the shrinkage pulling force generated by the plastic sealant can also be absorbed by the flexible deformation of the portion of the peripheral portion 212 located outside the first partition groove 2121, thereby avoiding the deformation of the main body 211 caused by the shrinkage pulling force and affecting the assembly accuracy of the components arranged on the main body 211 on the main body 211. At the same time, the first partition groove 2121 will not be exposed to the relay 10, which is conducive to improving the appearance integrity of the relay 10.

[0052] Of course, in some embodiments, the base 21 may also be provided with two first partition grooves 2121, which are respectively provided on the surface of the peripheral portion 212 facing the first side 213 and the surface facing the second side 214. The provision of the two first partition grooves 2121 is not likely to affect the structural strength of the peripheral portion 212, and is also conducive to fully absorbing the shrinkage pulling force generated by the plastic sealant, thereby reducing the risk of deformation of the main body 211. In this embodiment, the depth of the first partition groove 2121 facing the second side 214 may be greater than the depth of the first partition groove 2121 facing the first side 213, and the depth of the first partition groove 2121 facing the second side 214 may be greater than the depth of the glue dispensing groove 2221, so that the first partition groove 2121 facing the second side 214 can fully absorb the shrinkage pulling force generated by the plastic sealant, and the provision of the first partition groove 2121 facing the first side 213 effectively avoids deformation of the main body 211.

[0053] In some embodiments, the side plate 222 is provided with a second partition groove 2222 facing the second side 214, and in the direction from the peripheral portion 212 to the side plate 222, the first partition groove 2121, the glue dispensing groove 2221 and the second partition groove 2222 are sequentially arranged at intervals. It can be understood that the shrinkage pulling force generated by the plastic sealant may also cause the shell 22 to deform, and the second partition groove 2222 is arranged so that the part of the side plate 222 located inside the second partition groove 2222 can absorb the shrinkage pulling force generated by the plastic sealant through flexible deformation, which is conducive to reducing the risk of deformation of the shell 22 and improving the assembly accuracy and structural reliability of the shell 22 and the base 21. In this embodiment, the depth of the second partition groove 2222 can also be greater than the depth of the glue dispensing groove 2221. In the depth direction of the second partition groove 2222, at least part of the second partition groove 2222 corresponds to the glue dispensing groove 2221, so that the setting of the second partition groove 2222 can more fully absorb the shrinkage pulling force generated by the plastic sealant.

[0054] In the present application, the shapes of the first partition groove 2121, the second partition groove 2222 and the glue dispensing groove 2221 are not limited, including but not limited to groove structures of any applicable shapes such as U-shaped grooves and V-shaped grooves. When the base 21 is provided with two first partition grooves 2121, the shapes of the two first partition grooves 2121 can be the same or different, as long as they can absorb the shrinkage and pulling force generated by the plastic encapsulation glue.

[0055] Please see again Figure 1 and Figure 3As shown, in some embodiments, the first partition groove 2121 is arranged around the main body 211 and connected end to end, and the second partition groove 2222 is arranged around the base 21 and connected end to end, then the first partition groove 2121 and the second partition groove 2222 can be rectangular grooves adapted to the shapes of the base 21 and the shell 22. In this way, when the glue dispensing groove 2221 is arranged around the base 21 and connected end to end, the first partition groove 2121 and the second partition groove 2222 can fully absorb the shrinkage and pulling force generated by the plastic sealant at various parts of the circumference of the base 21, effectively reducing the risk of deformation of the base 21 and the shell 22.

[0056] Of course, in other embodiments, the first partition groove 2121 may also include a multi-segment groove structure, and the multi-segment groove structure of the first partition groove 2121 is sequentially spaced in the circumferential direction of the main body 211, and the second partition groove 2222 may also include a multi-segment groove structure, and the multi-segment groove structure of the second partition groove 2222 is sequentially spaced in the circumferential direction of the base 21. The number, size and distribution of the groove structures in the first partition groove 2121 and the second partition groove 2222 can be set according to the anti-deformation requirements of the base 21 and the shell 22, and are not limited in this application.

[0057] Further, in some embodiments, at least part of the first partition groove 2121 is located between the main contact assembly 12 and the glue dispensing groove 2221, and at least part of the first partition groove 2121 is located between the auxiliary contact assembly 13 and the glue dispensing groove 2221, thereby, the first partition groove 2121 can effectively prevent the portion of the base 21 where the main contact assembly 12 and the auxiliary contact assembly 13 are arranged from being deformed, thereby facilitating the guarantee of the assembly accuracy of the main contact assembly 12 and the auxiliary contact assembly 13 on the base 21. Of course, when other pins or components with higher assembly accuracy requirements are also arranged on the base 21, at least part of the first partition groove 2121 can also be located between these pins or components and the glue dispensing groove 2221 to guarantee the assembly accuracy of the pins and components on the base 21.

[0058] It is understandable that when the first partition groove 2121 surrounds the main body 211 and is connected end to end, all components arranged on the base 21 are located in the first partition groove 2121. The setting of the first partition groove 2121 can effectively prevent the deformation of the base 21 and improve the assembly accuracy of each component. In other embodiments, the first partition groove 2121 may also include a multi-segment groove structure, and the multi-segment groove structure of the first partition groove 2121 is respectively located between the main contact assembly 12 and the glue dispensing groove 2221, between the auxiliary contact assembly 13 and the glue dispensing groove 2221, and between other pins or components and the glue dispensing groove 2221. As long as the deformation risk of the parts of the base 21 where the components are arranged can be reduced and the assembly accuracy of each component on the base 21 can be improved, it can be used.

[0059] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0060] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
