DETAILED DESCRIPTION

[0041] The present invention is further described in detail below with reference to the accompanying drawings and embodiments.

[0042] In order to solve the problems of the prior art, such as the inability to balance material cost and life requirements, poor armature buffering performance, high working noise, and low armature connection strength, the present invention provides a split contact support, which sets the support assembly as an independent contact support part and a support connecting plate, so as to facilitate the selection of different materials, control material costs, and meet life requirements, and achieve the optimal balance between material cost control and life requirements; and improve the buffering performance of the armature, and reduce the working noise when the contactor is in action. The present invention provides a contactor based on the split contact support, which can control material costs, meet life requirements, and reduce working noise.

[0043] The split contact support described in the present invention is as follows: Figure 1 As shown, it includes a support assembly and an armature 30. The support assembly is used to set the contact, and the armature 30 is set on the support assembly. Among them, the support assembly includes a contact support part 10 and a support connecting plate 20. The contact support part 10 and the armature 30 are respectively set on both sides of the support connecting plate 20. It can be regarded that the contact support part 10 and the armature 30 are respectively set on the upper surface and the lower surface of the support connecting plate 20. Among them, the contact support part 10, the armature 30 and the support connecting plate 20 are detachably connected to facilitate disassembly, maintenance or replacement. When a nail-free installation structure is adopted, the installation and disassembly operations can be greatly simplified, and the production efficiency and maintenance efficiency can be improved.

[0044] like Figure 2 , Figure 3 As shown, the support connecting plate 20 is provided with an elastic support mechanism. When the armature 30 compresses the elastic support mechanism, the elastic support mechanism is elastically deformed, and the elastic support mechanism applies a reverse force to the armature 30, so that the elastic support mechanism forms an elastic support for the armature 30, thereby achieving a buffering effect for the armature 30. In order to prevent the elastic support mechanism from vibrating or displacing due to force compression and movement during the operation of the contactor, thereby causing a large working noise, the elastic support mechanism is implemented as an integral structure with the support connecting plate 20, that is, the elastic support mechanism is fixedly connected to at least one position of the support connecting plate 20, and does not displace under any circumstances, thereby avoiding working noise caused by impact or displacement friction, that is, reducing working noise.

[0045] In this embodiment, the elastic support mechanism is a support spring arm 21, which extends from the support connecting plate 20 toward the armature 30, and the connecting end of the support spring arm 21 is connected to the support connecting plate 20, and the top end of the support spring arm 21 extends toward the armature 30. Since the support spring arm 21 and the support connecting plate 20 are an integral structure, that is, they are made of the same material, compared with a separately arranged leaf spring, not only the strength of the connecting end is improved, but also the structural strength of the support spring arm 21 itself is consistent with the structural strength of the support connecting plate 20. From the perspective of common materials, both can be implemented to have a higher structural strength than a common leaf spring. In this embodiment, the contact support portion 10 is made of thermosetting material, and the support connecting plate 20 is made of thermoplastic material. The combination of thermosetting material and thermoplastic material can reduce material costs and meet the purpose of high product life requirements.

[0046] In the present invention, the armature 30 and the supporting connecting plate 20 are assembled by nail-free installation, and the armature 30 needs to be positioned by mechanical cooperation. Figure 5 As shown, the armature 30 is provided with a positioning groove 31 at the position corresponding to the top end of the supporting elastic arm 21, and the top end of the supporting elastic arm 21 is located in the positioning groove 31, forming a lateral top stop. That is, when the armature 30 is installed in place, the top end of the supporting elastic arm 21 is located in the positioning groove 31, and forms a top contact with the bottom of the positioning groove 31. At the same time, the top end of the supporting elastic arm 21 also forms a top contact with the side wall of the positioning groove 31, so that the armature 30 cannot be displaced in the top direction, achieving a positioning effect.

[0047] In order to better achieve the abutment contact and abutment limit, the abutment end of the support elastic arm 21 is provided with a positioning block 211 protruding toward the armature 30, and the positioning block 211 is located in the positioning groove 31. Since the shape of the positioning block 211 can be implemented as a more regular structure and has a certain height, the support elastic arm 21 does not need to be set too long to ensure the structural strength of the support elastic arm 21. In addition, the positioning block 211 has a larger surface contact with the side wall of the positioning groove 31, forming a more stable abutment fit and a better positioning effect.

[0048] Normally, the armature 30 is arranged perpendicular to the contact support portion 10, and in order to obtain stable movement, the contact support needs to be roughly arranged as a symmetrical structure, then the contact support portion 10 is located in the middle position of the armature 30, and the two ends of the armature 30 extend to the two ends of the support connecting plate 20 respectively, and the elastic support mechanism forms elastic supports at the two ends of the armature 30 to achieve a symmetrical balance effect.

[0049] In addition to the balanced support buffer at both ends of the armature 30, the two sides of the armature 30 also need to achieve balanced support buffering, so two supporting elastic arms 21 that are symmetrically arranged in opposite directions or in the same direction are arranged at the ends of the corresponding armature 30. That is, symmetrical support buffering in the width direction can be provided at both ends of the armature 30. This embodiment provides two different implementation structures.

[0050] like Figure 2 As shown, two support spring arms 21 located at one end of the support connecting plate 20 and at one end of the armature 30 are arranged opposite to each other along the width direction of the armature 30 and the width direction of the support connecting plate 20; and are arranged in mirror symmetry along the length direction of the armature 30 and the length direction of the support connecting plate 20. The support spring arms 21 are in an arc transition as a whole, and the space between the support spring arms 21 and the support connecting plate 20 can be implemented as a hollow or a non-hollow complete special-shaped surface.

[0051] like Figure 4 As shown, two support spring arms 21 located at one end of the support connecting plate 20 and at one end of the armature 30 are arranged in the same direction along the length direction of the armature 30 and the length direction of the support connecting plate 20, and are both arranged to face outward; and are symmetrically arranged along the length direction of the armature 30 and the length direction of the support connecting plate 20 along the central axis. Among them, the support spring arms 21 are in a straight line transition as a whole, and the space between the support spring arms 21 and the support connecting plate 20 can be implemented as a hollow or a non-hollow complete special-shaped surface.

[0052] Corresponding to the above two different structures of the supporting elastic arm 21, the positioning slot 31 on the armature 30 is adaptively adjusted to meet the requirements of the top limit. At the same time, in order to improve the application range of the armature 30 in actual production, such as Figure 5 As shown, the armature 30 can be provided with corresponding positioning grooves 31 for the above two different structures of the supporting spring arms 21. Furthermore, the armature 30 of the same specification can be applied to the contact support of different supporting spring arms 21 structures, saving mold opening costs and reducing inventory pressure.

[0053] The present invention also provides another matching structure between the supporting elastic arm 21 and the armature 30, such as Figure 6 , Figure 7As shown, the two supporting elastic arms 21 located at one end of the supporting connecting plate 20 and at one end of the armature 30 are arranged opposite to each other along the width direction of the armature 30 and the width direction of the supporting connecting plate 20; and are arranged in mirror symmetry along the length direction of the armature 30 and the central axis of the length direction of the supporting connecting plate 20. Among them, the supporting elastic arms 21 are overall in an arc transition, and the support elastic arms 21 and the supporting connecting plate 20 can be implemented as hollow or as a non-hollow complete special-shaped surface. Based on the elastic support for both ends of the armature 30, the positioning block 211 of the supporting elastic arm 21 is provided with a clamping step 212 on the inner side along the length direction of the supporting connecting plate 20. Corresponding to the clamping step 212, as shown Figure 8 As shown, the armature 30 is provided with a raised positioning protrusion 33, and the clamping step 212 and the positioning protrusion 33 form a clamping limit. The contour of the positioning protrusion 33 is adapted to the clamping step 212. In this embodiment, the positioning protrusion 33 is a semicircular boss, and the side facing the clamping step 212 is a flat surface. The clamping step 212 is a right-angled surface. The clamping step 212 and the positioning protrusion 33 are clamped at a right angle to form a limit in the inward direction. The clamping steps 212 at both ends cooperate to form a limit along the length direction of the armature 30.

[0054] At the same time, in order to improve the application range of the armature 30 in actual production, such as Figure 8 As shown, the armature 30 can be provided with corresponding positioning grooves 31 and positioning bumps 33 for the above two different structures of the supporting spring arms 21. Furthermore, the armature 30 of the same specification can be applied to the contact support of different supporting spring arms 21 structures, saving mold opening costs and reducing inventory pressure.

[0055] Since the present invention adopts a mechanical matching structure to replace the riveting process of the prior art to achieve the installation of the armature 30, it is necessary to set a structure for fixing the armature 30. In this embodiment, the connecting support plate is provided with a pair of mounting legs 22 toward the armature 30, and the armature 30 is positioned between the mounting legs 22. Specifically, the mounting legs 22 extend downward from the lower surface of the supporting connecting plate 20, are located at the edge of the supporting connecting plate 20, and are symmetrically arranged along the central axis of the length direction of the supporting connecting plate 20. In theory, one or more pairs of mounting legs 22 can be provided. When multiple pairs of mounting legs 22 are provided, preferably, they should be symmetrically arranged along the central axis of the width direction of the supporting connecting plate 20. In this embodiment, only one pair of mounting legs 22 is provided, and the mounting legs 22 are arranged on the central axis of the width direction of the supporting connecting plate 20.

[0056] The side walls facing the mounting legs 22 are provided with mounting grooves 221, and the opening angle of the mounting grooves 221 is consistent with the setting angle of the armature 30. The armature 30 slides into and is positioned along the mounting grooves 221 through the support blocks 32 on both sides. In this embodiment, assuming that the support connecting plate 20 is calibrated as a horizontal plane, the setting angle of the armature 30 is a horizontal angle parallel to the horizontal plane, and the opening angle of the mounting grooves 221 is a horizontal angle parallel to the horizontal plane. Under the clamping action of the mounting legs 22 on both sides, the armature 30 can be installed between the two mounting legs 22.

[0057] In order to facilitate the installation and positioning of the armature 30 in the sliding direction, one end of the installation slot 221 facing the sliding direction of the armature 30 is open, and the other end is closed. The open end is used for the armature 30 to slide into the installation slot 221, and the closed end defines the position where the armature 30 is installed. That is, after the armature 30 slides into the open end of the installation slot 221, the armature 30 is installed until it hits the closed end.

[0058] When the armature 30 is installed in place, the positioning block 211 of the supporting elastic arm 21 is clamped with the positioning groove 31 of the armature 30 to form a top stop. At the same time, in order to achieve positioning between the mounting leg 22 and the armature 30, and to form a hand feeling prompt when the mounting is in place, that is, when the armature 30 is installed in place, a hand feeling change similar to the suction effect is formed to confirm that the mounting is in place. In this embodiment, a receiving groove 223 is opened laterally outward near the closed end of the mounting groove 221, and the opening direction of the receiving groove 223 is approximately perpendicular to the mounting groove 221. That is, the receiving groove 223 is opened along the width direction of the supporting connecting plate 20, consistent with the protruding direction of the supporting block 32 of the armature 30, and the receiving groove 223 passes through the mounting leg 22. In order to achieve the tactile prompt, during the installation of the armature 30, the support block 32 is interference fit when sliding in the installation groove 221; until the support block 32 slides to the receiving groove 223, the receiving groove 223 makes way for the support block 32, and the support block 32 is positioned in the receiving groove 223.

[0059] In order to facilitate the installation of the armature 30, the side walls facing the mounting legs 22 are provided with a clearance groove 222 in the height direction, and the clearance groove 222 is communicated with the open end of the mounting groove 221. The setting of the clearance groove 222 makes it unnecessary to strictly align the support block 32 of the armature 30 with the open end of the mounting groove 221 when installing the armature 30, that is, the armature 30 only needs to approach the mounting legs 22, and at any position in the height direction of the mounting legs 22, it can first form a stop against the support block 32. When the support block 32 forms a stop against the clearance groove 222, the armature 30 is slid upward until it reaches the mounting groove 221, and then slides along the mounting groove 221 for installation. In order to facilitate the transition of the support block 32 from the clearance groove 222 to the mounting groove 221, the corner position of the clearance groove 222 and the mounting groove 221 is set as an inclined surface, and the support block 32 can be tilted along the inclined surface from the clearance groove 222 to the mounting groove 221.

[0060] In order to further buffer the armature 30 and further reduce the working noise, as Fig. 9 As shown, a buffer pad 40 is provided between the armature 30 and the support connecting plate 20. The buffer pad 40 and the elastic support mechanism work together to provide buffer support for the armature 30 and reduce the working noise. In this embodiment, the buffer pad 40 is provided with a protruding embedding block 41 facing the support connecting plate 20. The support connecting plate 20 is provided with an embedding groove 26 corresponding to the block 12, and the embedding block 41 is embedded in the embedding groove 26. The positioning of the buffer pad 40 on the support connecting plate 20 is achieved by the cooperation of the embedding block 41 and the embedding groove 26 to prevent displacement and falling off due to long-term work. During installation, the cooperation of the embedding block 41 and the embedding groove 26 ensures that the buffer pad 40 can be better maintained in the preset position and installed in the correct position.

[0061] In the present invention, the contact support portion 10 and the support connecting plate 20 adopt a nail-free quick-installation structure. Figure 2 , Figure 3 , Fig.10 , Fig.11As shown, the contact support part 10 and the support connecting plate 20 are connected by transverse sliding through the dovetail groove 11 and the dovetail tenon 23; the end of the dovetail tenon 23 forms a top stop against the side wall of the dovetail groove 11 through the transversely extending limit baffle 24. In this embodiment, the dovetail groove 11 is provided on the end surface of the contact support part 10 facing the support connecting plate 20, and the dovetail tenon 23 is provided on the support connecting plate 20 corresponding to the dovetail groove 11, and the limit baffle 24 is provided at least at the end of the dovetail tenon 23 located on both sides of the support connecting plate 20. In order to simplify the structure, the limit baffle 24 is only provided at the end of the dovetail tenon 23 located on both sides of the support connecting plate 20, so as to form a left-right balanced limit for the contact support part 10. In order to save costs and simplify the structure, the limit baffle 24 can be provided only at the end of the dovetail tenon 23 located on both sides of the support connecting plate 20. During the assembly process, assuming that the supporting connecting plate 20 does not move, the dovetail groove 11 of the contact supporting part 10 approaches the dovetail tenon 23 of the supporting connecting plate 20 and slides in alignment. When the side wall of the dovetail groove 11 abuts against the limit stopper 24, the contact supporting part 10 and the supporting connecting plate 20 are assembled in place and positioned in the sliding direction.

[0062] As for the limit in the sliding-out direction, the contact support part 10 and the support connecting plate 20 form a buckle limit through the claw 25 of the side wall and the block 12 to achieve the limit in the sliding-out direction. The claw 25 extends in the sliding connection direction. When the side wall of the dovetail groove 11 slides to abut against the limit baffle 24, the claw 25 passes over the block 12 to form a buckle limit, and forms a position in the sliding-out direction. In this embodiment, the support connecting plate 20 is provided with a claw 25 on at least one side, and correspondingly, the block 12 is provided on the side wall of the contact support part 10, and the claw 25 forms a height difference with the block 12, and the claw 25 is provided with a hook 251 protruding toward the block 12. Since the claw 25 has a certain length and is elastic, when the contact support part 10 is assembled with the supporting connecting plate 20, the hook 251 of the claw 25 first abuts against the buckle; the sliding assembly is continued, and under the extrusion of the block 12, the claw 25 is elastically deformed downward, and with the elastic deformation of the claw 25, the hook 251 moves to the bottom of the block 12; the sliding assembly is continued until the hook 251 moves to a position exceeding the block 12, the claw 25 is elastically reset, and the hook 251 moves upward to form a buckle with the block 12, so as to achieve the limit in the sliding direction. Then, through the limit baffle 24 and the hook 251, the side wall of the dovetail groove 11 and the block 12, the contact support part 10 forms a positioning setting. When disassembling, it is only necessary to press the claw 25 downward to make the hook 251 separate from the block 12, and then push it to slide out. In order to facilitate the squeezing between the barb 251 and the clamping block 12 so as to more smoothly force the clamping claw 25 to elastically deform and the barb 251 to descend, in this embodiment, the relative position of the barb 251 and the clamping block 12 is set to a matching inclined surface.

[0063] Based on the split contact support, the present invention also provides a contactor, such as Fig.12 As shown, it includes a base 50, a base 60, and a split contact support, and the moving contact is arranged on the contact support portion 10 of the split contact support. The contactor is based on the split contact support, thereby controlling material costs, meeting life requirements, and reducing working noise.
