Abstract
Description
Technical Field
[0001] The present application relates to the technical field of electrical switches, and in particular to a contact support and a contactor. Background Art
[0002] In the related art, a contactor such as a contactor generally includes structures such as a stationary contact, a contact bridge and a housing. When in use, the contact bridge slides along a window of the housing under the cooperation of structures such as an electromagnet and a contact spring to achieve contact or separation between the contact bridge and the stationary contact. In this process, a guide strip needs to be provided in the housing window to guide and position the sliding of the contact bridge.
[0003] However, when the above structure is used, due to the limitations of injection molding process parameters and other conditions, coupled with the continuous application of force to a specific position in the window during the movement of the contact bridge, weak areas are easily formed in the window, and the weak areas are prone to breakage during use, resulting in a reduction in the service life of the contact support. Utility Model Content
[0004] The purpose of the present application is to provide a contact support and a contactor, which can solve the problem that the contact support is prone to breakage during use, which affects the service life.
[0005] In order to achieve the above-mentioned purpose, the present application provides a contact support, the contact support includes a support seat, a contact bridge, a first reinforcement part and at least one guide frame, wherein the guide frame is installed on the support seat, the guide frame has a guide window, a guide rib is arranged in the guide window, and the end of the guide rib away from the support seat has a first weak area. The contact bridge is partially located in the guide window, and the contact bridge is slidably connected to the guide rib. The first reinforcement part is arranged in the guide window, and part of the first reinforcement part is arranged in the first weak area, and the first reinforcement part is connected to the guide rib and forms a first reinforcement step.
[0006] Based on the above-mentioned embodiments of the present application, due to the limitations of the processing conditions of the guide frame itself, the end of the guide frame itself that is away from the support seat is relatively weak. At the same time, when the contact bridge slides in the guide frame, it will continuously apply force to the guide frame body along the sliding direction, which eventually leads to the formation of a first weak area at the end of the guide rib in the guide frame that is away from the support seat. In the present application, a first reinforcement portion is provided in the first weak area, and a first reinforcement step formed by connecting the first reinforcement portion and the guide rib can reinforce the first weak area by directly increasing the thickness, thereby avoiding fracture at the position of the first weak area during use, which affects the service life of the contact support.
[0007] In some embodiments, a surface of the first enhanced step close to the support seat is a plane or a curved surface.
[0008] Based on the above-mentioned embodiments of the present application, while meeting the reinforcement requirements, the surface of the first reinforcement step close to the support seat can be set to either a plane or a curved surface. When set to a plane, it is easy to process, and when set to a curved surface, it is smoother and more uniform, and has better tear resistance.
[0009] In some embodiments, the plane of the first reinforcement step close to the support seat is a first plane, the plane of the guide frame provided with guide ribs is a second plane, and the angle between the first plane and the second plane is α, α≥90°.
[0010] Based on the above embodiments of the present application, the angle between the first plane and the second plane is set to a right angle or an obtuse angle. When the angle between the first plane and the second plane is a right angle, the structure between the two planes is relatively simple and convenient to process. When the angle between the two planes is closer to an obtuse angle, the connection position between the two planes is more gentle, and the possibility of tearing at the intersection of the two planes is gradually reduced, thereby further reducing the risk of fracture in the first weak area.
[0011] In some embodiments, a transition surface is provided at the intersection of the first plane and the second plane, and the transition surface is an arc surface or a plane.
[0012] Based on the above-mentioned embodiments of the present application, by setting a transition surface at the intersection of the first plane and the second plane, it is possible to avoid an obvious turning area at the intersection of the two planes, so that the intersection between the two planes is smoother, reducing the possibility of fracture in the intersection area between the two planes.
[0013] In some embodiments, at least two guide frames are provided, and two adjacent guide frames are connected to each other, and the first reinforcing portion is provided in the guide frame at the edge, or the first reinforcing portion is provided in all the guide frames.
[0014] Based on the above-mentioned embodiments of the present application, when other guide frames are provided on both sides of the guide frame to be connected thereto, the force on both sides of the guide frame is relatively balanced, and when the guide frame is located at the edge, only one side of the guide frame is connected to other guide frames, so uneven force will occur, causing the guide frame located at the edge to be more likely to break. Therefore, when setting the first reinforcement part, it is preferred to set the first reinforcement part in the guide frame located at the edge, and reinforcement parts can also be set in all guide frames to enhance the overall strength.
[0015] In some embodiments, the guide rib cooperates with the inner wall of the guide frame to form two opposite guide steps, and each guide rib is cooperated with two first reinforcement parts, and the two first reinforcement parts are respectively connected to the corresponding guide steps.
[0016] Based on the above-mentioned embodiments of the present application, by setting two guide ribs, the fixing and guiding effects are better when positioning and guiding the contact bridge. At the same time, the two first reinforcement parts reinforce the position of the first weak area from both sides respectively, so that the strength after reinforcement is more balanced, avoiding unilateral tearing first.
[0017] In some embodiments, the guide ribs are disposed on two opposite wall surfaces of the guide frame, and clamping grooves are disposed on both sides of the contact bridge, and the clamping grooves are slidably connected to the guide ribs.
[0018] Based on the above-mentioned embodiments of the present application, guide ribs are provided on both sides, which not only improves the positioning effect of the contact bridge but also makes the guiding process of the contact bridge smoother.
[0019] In some embodiments, at least two guide frames are provided, and two adjacent guide frames are connected by connecting ribs, the connecting ribs extend in a direction away from the support seat, and the first reinforcing portion extends in a direction close to the support seat, and the first reinforcing portion at least partially overlaps with the connecting ribs.
[0020] Based on the above-mentioned embodiments of the present application, by arranging the first reinforcement part to overlap with the connecting rib, the first reinforcement part, the guide frame in which it is located, and the adjacent guide frames are connected as a whole through the connecting rib, and the connection foundation of the first reinforcement part is more solid, thereby strengthening the first weak area as a whole.
[0021] In some embodiments, the guide rib has a second weak area at the end near the support seat, and the contact support also includes a second reinforcement portion, which is arranged in the guide window, and part of the second reinforcement portion is arranged in the second weak area.
[0022] Based on the above-mentioned embodiments of the present application, when the first weak area is broken or slightly torn, a second weak area will be formed at the end of the guide rib close to the support seat due to uneven force. By providing a second reinforcement part, the second weak area is strengthened, thereby achieving a double insurance effect.
[0023] According to a second aspect of the present application, a contactor is provided, comprising the above-mentioned contact support and a housing, wherein the housing has a receiving cavity, and the contact support is disposed in the receiving cavity.
[0024] Based on the above embodiments of the present application, the service life of the contact support is extended through the above configuration, thereby extending the service life of the contactor as a whole.
[0025] Other features and advantages of the present application will be described in detail in the subsequent detailed description. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.
[0037] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application described and shown in the drawings here can be arranged and designed in various different configurations.
[0038] Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the present application for protection, but merely represents selected embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present application.
[0039] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.
[0040] In the description of this application, it should be noted that, in the absence of any contrary explanation, the terms "inside", "outside", etc. indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, or the orientation or positional relationship in which the product of the application is usually placed when in use, which is only for the convenience of describing this application and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on this application. In addition, the terms "first", "second", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.
[0041] In the description of this application, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "disposed" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.
[0042] refer to Figure 1 As shown in the prior art, the contact support member includes a plurality of guide frames 2, and two adjacent guide frames 2 are connected by connecting strips. A guide strip is arranged in each guide frame 2, and the guide strip can play a guiding and positioning role when the movable contact bridge slides.
[0043] In specific use, when the movable contact bridge slides along the guide frame 2 under the cooperative drive of structures such as the electromagnet and the contact spring, a continuous impact force will be generated on the end of the guide frame 2 that is on the sliding path, and the guide frame 2 is generally processed by injection molding. During the processing, the bending part of the frame body itself is relatively fragile. At this time, a weak area is easily formed at the position of area A at the bending part of the guide frame 2, and the position of area A is prone to breakage during the use of the contact support.
[0044] When the position of area A is broken or partially torn, the diagonal position of area A is prone to unilateral tearing due to uneven force when the contact support continues to be used, that is, a second weak area is easily formed in area B.
[0045] Especially for the guide frame 2 located at the edge, since only one side of the edge guide frame 2 is provided with a connecting strip for connecting with the adjacent guide frame 2, the strength of the two sides of the guide frame 2 is inconsistent, so it is more likely to break during use.
[0046] In order to solve the above technical problems, refer to Figures 2 to 7 As shown in , the present application provides a contact support member, which includes a support seat 1, a contact bridge 3, a first reinforcement portion 4 and at least one guide frame 2, wherein the guide frame 2 is installed on the support seat 1, and the guide frame 2 has a guide window 21, and a guide rib 22 is arranged in the guide window 21, and the end of the guide rib 22 away from the support seat 1 has a first weak area 23. The contact bridge 3 is partially located in the guide window 21, and the contact bridge 3 is slidably connected to the guide rib 22. The first reinforcement portion 4 is arranged in the guide window 21, and part of the first reinforcement portion 4 is arranged in the first weak area 23. The first reinforcement portion 4 is connected to the guide rib 22 and forms a first reinforcement step 41.
[0047] Based on the above-mentioned embodiments provided by the present application, due to the limitations of factors such as the processing conditions of the guide frame 2 itself, the part of the guide frame 2 that is away from the support seat 1 is relatively weak. At the same time, when the contact bridge 3 slides in the guide frame 2, it will continuously apply a force to the frame body of the guide frame 2 along the sliding direction, which eventually causes the end of the guide rib 22 in the guide frame 2 to be away from the support seat 1 to form a first weak area 23, wherein the first weak area 23 corresponds to area A in the prior art. In the contact support provided by the present application, a first reinforcement portion 4 is provided in the first weak area 23, and the first reinforcement portion 4 is connected to the guide rib 22 to form a first reinforcement step 41. The provision of the first reinforcement step 41 can directly increase the thickness of the frame body of the guide frame 2 at the first weak area 23, thereby directly strengthening the first weak area 23, reducing or even avoiding the occurrence of fracture at the position of the first weak area 23 during use, which affects the service life of the contact support.
[0048] Specifically, the structure of the support seat 1 in the present application can be selected in any suitable setting mode. The shape of the support seat 1 can be designed according to factors such as strength requirements and heat dissipation requirements during the specific design and processing process, and the guide frame 2 can be integrally processed with the support seat 1, for example, it can be integrated with the support seat 1 by injection molding, or the guide frame 2 can be processed separately and then connected to the support seat 1, for example, the separately processed guide frame 2 and the support seat 1 are connected by means of snap-fitting or gluing.
[0049] Furthermore, in the present application, any suitable connection method can be used between the guide rib 22 and the guide frame 2, for example, the guide rib 22 is directly integrated into the guide window 21, and is integrally formed with the guide frame 2 by injection molding or other processing methods, so as to facilitate processing while ensuring sufficient connection strength between the two. In addition, a variety of connection methods including integrated molding can be used between the first reinforcement part 4 and the guide rib 22. When the first reinforcement part 4 and the guide rib 22 are formed by integrated processing, a high connection strength between the two can be ensured.
[0050] In addition, it should be noted that the specific driving components of the contact bridge 3 in the present application can be set to a variety of driving structures including contact springs and electromagnets. When the driving structure is set to contact springs and electromagnets, the contact bridge 3 is driven to slide along the guide frame 2 through the elasticity of the contact springs and the magnetic attraction of the electromagnets. Since the present application does not involve improvements to this part of the structure, it will not be repeated here.
[0051] In the present application, the specific structure of the first enhanced step 41 can be selected in any suitable manner, see Figure 2 As shown in , in an exemplary embodiment provided in the present application, the surface of the first reinforcing step 41 close to the support seat 1 can be set to a flat surface or a curved surface.
[0052] Based on the above-mentioned embodiment provided in the present application, the first reinforcement step 41 is arranged in the first weak area 23 to reinforce it. Therefore, the first reinforcement step 41 only needs to ensure the connection strength with the connection position with the guide rib 22 and the guide frame 2, while ensuring the strength of the first reinforcement step 41 itself, and the side of the first reinforcement step 41 close to the support seat 1 can be set arbitrarily.
[0053] When the side of the first reinforcing step 41 close to the support seat 1 is set as a plane, the planar step surface is easy to realize by injection molding and other processing methods, which reduces the process difficulty and processing cost, while also taking into account the strength of the first reinforcing step 41 itself.
[0054] When the first reinforcing step 41 is set as an arc surface on one side close to the support seat 1, since the arc surface is relatively smooth and uniform at each position, there is no obvious division or turning position, and stress concentration is not easy to occur, so the tear resistance is stronger. At this time, the connection strength of the first reinforcing step 41 is higher, but the processing difficulty is correspondingly increased when injection molding and other processing methods are used. Therefore, in the specific processing process, any suitable setting method can be selected according to the processing requirements and strength requirements, and the present application does not make specific limitations on this.
[0055] Further, refer to Figures 2 to 6As shown in the figure, in the present application, the plane of the first reinforcement step 41 close to the support seat 1 can be the first plane 42, the plane on which the guide rib 22 is arranged in the guide frame 2 can be the second plane 43, and the angle between the first plane 42 and the second plane 43 is α, α≥90°.
[0056] Based on the above embodiments provided in the present application, the angle between the first plane 42 and the second plane 43 is set to a right angle or an obtuse angle. When the angle between the first plane 42 and the second plane 43 is a right angle, the first plane 42 and the second plane 43 are perpendicular to each other. At this time, the structure between the two is relatively simple and convenient to process.
[0057] Since the sliding direction of the contact bridge 3 is consistent with the extension direction of the guide rib 22, and the guide rib 22 is formed on the second plane 43, when the angle α between the first plane 42 and the second plane 43 is ≥90° and approaches a right angle, the turning point between the two is more obvious, and the connection between the two is more likely to tear. When the angle between the two approaches an obtuse angle, the connection position between the two is more gentle, and the possibility of tearing at the intersection of the two is gradually reduced, thereby further reducing the risk of fracture of the first weak area 23.
[0058] When the angle α between the first plane 42 and the second plane 43 is less than 90°, it is an acute angle. At this time, the stress concentration at the connection between the two is more obvious and tearing is prone to occur. Therefore, the angle α between the first plane 42 and the second plane 43 of the present application is ≥90°.
[0059] Further, refer to Figure 5 As shown in , in the present application, a transition surface 44 may be provided at the intersection of the first plane 42 and the second plane 43, and the transition surface 44 may be an arc surface or a plane. That is, a chamfer or rounded structure is provided at the intersection of the first plane 42 and the second plane 43, and the provision of the transition surface 44 makes the connection between the first plane 42 and the second plane 43 smoother, reduces the possibility of an obvious bending area at the connection between the two, and reduces the risk of fracture at the connection between the two.
[0060] refer to Figure 2 and Figure 4 As shown in , in the present application, at least two guide frames 2 are provided, adjacent guide frames 2 are connected to each other, a first reinforcing portion 4 is provided in the guide frame 2 at the edge, or a first reinforcing portion 4 is provided in all guide frames 2 .
[0061] Based on the above-mentioned embodiment provided in the present application, when two guide frames 2 are provided, the two guide frames 2 are connected to each other. At this time, the two guide frames 2 are both at the edge position. At this time, uneven force will occur on the side where the guide frames 2 are connected to each other and the side away from each other, causing the guide frames 2 to easily break during use. Therefore, the strength can be enhanced by setting a first reinforcement portion 4 in both guide frames 2 to avoid breakage.
[0062] When there are three guide frames 2, two adjacent guide frames 2 are connected to each other. At this time, the guide frame 2 in the middle is connected to other guide frames 2 on both sides, so the forces on both sides are relatively balanced, while the two guide frames 2 on both sides are only connected to other guide frames 2 on one side, so there will be uneven forces on both sides, which will make the two guide frames 2 on both sides more likely to break during use. At this time, the first reinforcement part 4 can be set in all guide frames 2 to strengthen the strength of all guide frames 2, or the first reinforcement part 4 can be set only in the guide frames 2 on both sides that are prone to breakage, so as to save materials and reduce costs while strengthening. The specific setting method can be selected according to actual needs, and this application does not make specific restrictions on this.
[0063] Furthermore, when the number of guide frames 2 is four, five, or even more, the two guide frames 2 on both sides are prone to breakage due to uneven force, while the multiple guide frames 2 in the middle are balanced in force. Therefore, the first reinforcement part 4 can be set in all guide frames 2, or only in the two guide frames 2 on both sides. The specific number of guide frames 2 can be set according to the specific connection requirements of the contact support.
[0064] In addition, in some other embodiments of the present application, reference Figure 2 As shown in , the guide frame 2 may also include an auxiliary guide frame 7, in which an auxiliary contact bridge 71 is slidably arranged. Usually, one auxiliary guide frame 7 is arranged at the edge of other guide frames 2, and the auxiliary guide frame 7 is smaller in size than other guide frames 2. The sliding distance of the auxiliary contact bridge 71 in the auxiliary guide frame 7 is also smaller than that of other contact bridges 3. Therefore, the auxiliary guide frame 7 has a high strength, and the force applied by the auxiliary contact bridge 71 to the auxiliary guide frame 7 is small. Therefore, the auxiliary guide frame 7 usually does not break during use. Therefore, when one edge of multiple guide frames 2 is set as an auxiliary guide frame 7, the first reinforcement part 4 may not be arranged in the auxiliary guide frame 7, and the first reinforcement part 4 is only arranged in the guide frame 2 at the other edge.
[0065] refer to Figure 2 As shown in the figure, in the present application, the guide rib 22 cooperates with the inner wall of the guide frame 2 to form two opposite guide steps, and each guide rib 22 is provided with two first reinforcement parts 4, which are respectively connected to the corresponding guide steps.
[0066] Based on the above embodiments provided by the present application, by forming two guide steps, the force on both sides of the contact bridge 3 can be made more uniform when positioning and guiding the contact bridge 3, so that the contact bridge 3 can be better guided and the sliding process of the contact bridge 3 is smoother. By setting the first reinforcement part 4 corresponding to each guide step, the strength of both sides of the guide rib 22 is strengthened at the same time, avoiding unilateral tearing due to uneven force on both sides of the guide rib 22. Among them, the two guide steps can be symmetrically arranged, and the two first reinforcement parts 4 connected thereto are also symmetrically arranged. The symmetrically arranged first reinforcement parts 4 can make the force on both sides more balanced, further reducing the risk of unilateral tearing first.
[0067] refer to Figure 2 As shown in , guide ribs 22 are provided on two opposite wall surfaces of the guide frame 2 , and clamping grooves 31 are provided on both sides of the contact bridge 3 , and the clamping grooves 31 are slidably connected to the guide ribs 22 .
[0068] Based on the above-mentioned embodiment provided in the present application, guide ribs 22 are arranged on the opposite wall surfaces of the guide frame 2, and the two guide ribs 22 are engaged with the slots 31 on both sides of the contact bridge 3. Compared with the arrangement of the single-sided guide ribs 22, the structure of the double-sided guide ribs 22 is more stable for the engagement of the contact bridge 3, and also makes the sliding process of the contact bridge 3 smoother.
[0069] In addition, the specific shape of the guide rib 22 in the present application can be selected in any suitable setting mode. For example, the cross-section of the guide rib 22 can be set to a variety of shapes including a rectangle, an isosceles trapezoid or an arc, and the shape of the slot 31 in the contact bridge 3 is also set to a shape that matches the guide rib 22. The specific shape can be selected according to the assembly requirements, and the present application does not impose specific restrictions on this.
[0070] refer to Figure 3 and Figure 6 As shown in the figure, at least two guide frames 2 are provided, and two adjacent guide frames 2 are connected by connecting ribs 5, the connecting ribs 5 extend in a direction away from the support seat 1, and the first reinforcing portion 4 extends in a direction close to the support seat 1, and the first reinforcing portion 4 at least partially overlaps with the connecting ribs 5.
[0071] Based on the above-mentioned embodiment provided in the present application, the first reinforcing portion 4 and the connecting rib 5 are at least partially overlapped by setting the overlapping distance between the first reinforcing portion 4 and the connecting rib 5 is H1. When there is an overlapping area between the first reinforcing portion 4 and the connecting rib 5, the first reinforcing portion 4 is connected to the connecting rib 5 and other guide frames 2 through the frame body of the guide frame 2 in which it is located. At this time, the first reinforcing portion 4, the frame body of the guide frame 2 in which it is located, and the connecting rib 5 are connected as a whole, so that the connection foundation at the first reinforcing portion 4 is more solid and breakage is avoided.
[0072] Furthermore, in the present application, the length of H1 can be extended by extending the connecting rib 5, or by extending the first reinforcement portion 4, or by extending the connecting rib 5 and the first reinforcement portion 4 at the same time. Any appropriate setting method can be selected based on factors such as processing requirements, and the present application does not impose any specific restrictions on this.
[0073] In addition, it should be noted that the reference Figure 3 As shown in, in the present application, under the condition that the first reinforcement part 4 and the connecting rib 5 at least partially overlap, the distance between the surface of the first reinforcement step 41 close to the support seat 1 and the corresponding wall surface of the guide window 21 should also meet the requirement that the contact bridge 3 overtravels without interference, wherein the distance between the surface of the first reinforcement step 41 close to the support seat 1 and the corresponding wall surface of the guide window 21 is H2, and the size of H2 in specific use can be selected according to the travel distance of the contact support.
[0074] refer to Figure 2 As shown in FIG. 1 , the end of the guide rib 22 close to the support seat 1 has a second weak area 24 , and the contact support also includes a second reinforcement portion 6 , which is arranged in the guide window 21 , and part of the second reinforcement portion 6 is arranged in the second weak area 24 .
[0075] Based on the above embodiments provided in the present application, the second weak area 24 in the present application corresponds to area B in the prior art, and the position of the second weak area 24 is reinforced by setting a second reinforcement portion 6 in the second weak area 24. At this time, even if the first weak area 23 is slightly torn, resulting in uneven force on the position of the second weak area 24, the possibility of tearing in the second weak area 24 can be reduced or even avoided by setting the second reinforcement portion 6, thereby achieving a double insurance effect.
[0076] On the basis of the above technical solution, the second aspect of the present application further provides a contactor, which includes the above contact support and a shell, wherein the shell has a receiving cavity, and the contact support is arranged in the receiving cavity.
[0077] Based on the above embodiments provided in the present application, the contactor realizes switching through the internal contact support when in use. When the above structure of the contact support is applied to the contactor, the service life of the entire contact support is extended through the setting of the above structure, thereby increasing the service life of the entire contactor.
[0078] The preferred embodiments of the present application are described in detail above in conjunction with the accompanying drawings; however, the present application is not limited to the specific details in the above embodiments. Within the technical concept of the present application, a variety of simple modifications can be made to the technical solution of the present application, and these simple modifications all fall within the protection scope of the present application.
[0079] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, this application will not further describe various possible combinations.
[0080] In addition, the various implementation modes of the present application may be arbitrarily combined, and as long as they do not violate the concept of the present application, they should also be regarded as the contents disclosed in the present application.
