[0043] The technical solution of this utility model will be further described below with reference to the embodiments and accompanying drawings.
[0044] Example 1
[0045] Please see Figures 1 to 10 The relay 100 provided in this embodiment of the present utility model is easy to install and includes a base 10, a push card 20, a main contact portion 30, a coil drive portion 40, an armature portion 50, and a housing 70.
[0046] Please refer to Figures 1 to 4The outer casing 70 has an installation space; the base 10 is located within the installation space and includes a separate main body 11 and side plates 12. The main body 11 has a first installation opening 114 on its first side 14 along the X direction; a push card 20 is slidably disposed on the main body 11, and the first end 23 of the push card 20 has a card groove 21, with an opening 22 facing the first side 14; the main contact portion 30 includes an active contact structure 31 and a main static contact structure 32, with the main static contact structure 32 located at the third end 15 of the main body 11 along the Y direction. The active contact structure 31 is snapped into the second end 24 of the push card 20; the coil drive part 40 is installed in the fourth end 16 of the main body 11 along the Y direction, including the frame 41, the coil 42, the iron core 43, and the first yoke 44 and the second yoke 45 located at both ends of the iron core 43. The first yoke 44 is located close to the bottom wall of the main body 11, and the first yoke 44 and the second yoke 45 are connected to the side plate 12; the armature part 50 can be snapped into the slot 21 through the opening 22 along the X direction, and rotate relative to the main body 11 and the side plate 12.
[0047] The aforementioned easy-to-install relay 100, by setting the base 10 as a separate unit, forms a first mounting port 114 on the main body 11, and provides an opening 22 at one end of the push card 20 for the armature part 50 to be inserted. When installing the push card 20, the main contact part 30, the coil drive part 40, and the armature part 50, the active contact structure 31 in the main contact part 30 is installed at one end of the push card 20, so that the active contact structure 31 and the push card 20 are used as a preliminary installation body. The main static contact structure 32, the preliminary installation body, and the coil drive part 40 are then installed on the main body 10 in sequence. Finally, the armature part 50 is inserted into the slot 21 of the push card 20 through the opening 22. In this way, the push card 20, the main contact part 30, the coil drive part 40, and the armature part 50 are installed in multiple steps, which reduces the assembly precision with the base 10 and makes the assembly of the entire relay easier.
[0048] Understandably, the main body 10 has a second mounting opening 115 on the second side along the Y direction so that the active contact structure 31, the main static contact structure 32, the coil drive part 40 and the armature part 50 can be exposed from the second mounting opening 115.
[0049] Please refer to Figure 4 and Figure 5The active contact structure 31 includes a copper terminal 311, a pressure plate 312, multiple moving springs 313, and an active contact 314 disposed on the moving springs 313. The multiple moving springs 313 are riveted to one end of the copper terminal 311, and the other end of the copper terminal 311 is provided with a relief groove. The push card 20 passes through the relief groove 3111. The pressure plate 312 is connected to the other end of the multiple moving springs 313 and is locked to the second end 24 of the push card 20, thereby realizing the closing or opening between the active contact 314 and the main static contact structure 32 by the sliding of the push card 20.
[0050] Specifically, when installing the pressure plate 312 and the push card 20, the pressure plate 312 includes a mounting part 3121 and a deformation part 3122. The mounting part 3121 is connected to a plurality of movable springs 313. The deformation part 3122 abuts against the groove wall of the mounting groove 25 of the second end 24 of the push card 20, so that the push card 20 pushes the deformation part 3122 to deform, thereby causing the plurality of movable springs 313 to deform.
[0051] In this embodiment, the main stationary contact structure 32 includes a main stationary spring 321 and a main stationary contact 322 disposed on the main stationary spring 321. The main stationary contact 322 is used to close or open the active contact 314, thereby realizing the control of the on / off of the external load.
[0052] Please see Figure 6 The relay in this embodiment also includes an auxiliary contact portion 60. The main contact portion 30 is used to control the on / off state of the external load, and the auxiliary contact portion 60 is used to input a feedback signal to the external circuit, indicating that the push card 20 has driven the main contact structure to achieve engagement or disengagement.
[0053] The auxiliary contact portion 60 includes an auxiliary moving contact structure 61 and an auxiliary stationary contact structure 62. The auxiliary moving contact structure 61 is movably connected to the armature portion 50, or it can be driven by the armature portion 50 to deform, thereby achieving on / off control between it and the auxiliary stationary contact structure 62. In this way, by setting the auxiliary moving contact structure 61 to be driven to deform by the armature portion 50, compared to the method of mounting the auxiliary moving contact structure 61 on the push card 20, the entire auxiliary contact portion 60 and the main contact portion 30 mounted on the other end of the push card 20 have a longer distance. This allows for a larger distance between the two contact portions, preventing arcing between them from affecting each other when the contacts in the two contact portions are disconnected, thereby improving the safety performance of the entire relay.
[0054] Please refer to Figure 6In this embodiment, the armature portion 50 includes an armature 51 and an injection-molded part 52, as well as a magnet disposed within the injection-molded part 52. The magnet is used to establish a magnetic path with the two armatures 51. The injection-molded part 52 includes an integrally formed mounting body 521, a rotating shaft 522, and a rotating arm 523. The armature 51 is integrally formed within the mounting body 521 and is oscillating relative to the first yoke and the second yoke. The rotating shaft 522 is rotatably disposed with the main body 11 and the side plate 12. The rotating arm 523 is rotatably disposed with the first end 23 of the push card 20. Thus, by integrally molding the injection-molded part 52, it is not necessary to additionally provide a rotating shaft for the injection-molded part 52 to rotate relative to the base 10, which facilitates the installation of the armature portion 50 and the entire relay, thereby improving the installation efficiency of the relay.
[0055] Please see Figure 2 In one embodiment of this utility model, in order to facilitate the installation of the coil driving part 40, a first positioning structure 451 is provided on the second yoke 45 along the Z direction, and a second positioning structure 111 is provided on the main body 11. The first positioning structure 451 and the second positioning structure 111 can be inserted and engaged along the X direction. Thus, when the coil driving part 40 is installed on the main body 11, the insertion and engagement of the first positioning structure 451 and the second positioning structure 111 can realize the positioning and limiting of the coil driving part 40 on the main body 11 along the X direction.
[0056] In one embodiment, the first positioning structure 451 can be configured as a positioning post and the second positioning structure 111 can be configured as a positioning groove; or the first positioning structure 451 can be configured as a positioning groove and the second positioning structure 111 can be configured as a positioning post.
[0057] Specifically, since the second yoke 45 is made of metal and has greater structural strength, it is fitted with a positioning post on the second yoke 45 and a positioning groove on the base 10 to achieve insertion and mating with the coil drive part 40. Thus, when the coil drive part 40 is installed, after the coil drive part 40 is pushed into place, the positioning post is locked in the positioning groove, thereby initially achieving the installation and positioning of the coil drive part 40.
[0058] Since the second yoke 45 is installed inside the frame 41, in order to achieve positioning and installation with the main body 11, the base 10 also includes a limiting plate 17. The limiting plate 17 is located at one end of the main body 11 along the Z direction and has the aforementioned positioning groove. The limiting plate 17 and the second yoke 45 abut against each other to limit the second yoke 45 along the Y direction. Thus, the setting of the limiting plate 17 not only facilitates the forming of the positioning groove, but also increases the structural strength of the entire main body 11; at the same time, it realizes the limitation of the coil driving part 40 in the Y direction.
[0059] Specifically, please refer to Figure 2 , Figure 3, Figures 7 to 9 The second yoke 45 includes a first connecting part 452 and a first mating part 453 arranged at an angle. The first connecting part 452 is connected to the iron core 43 and is provided with a first positioning structure 451. The first mating part 453 is used to engage with the armature part 50. The limiting plate 17 includes a first limiting part 171 and a second limiting part 172 arranged at an angle. The first limiting part 171 is provided with a second positioning structure 111. The second limiting part 172 is used to abut against the first mating part 453 in the Y direction. Thus, when the coil driving part 40 is positioned and installed, not only through the cooperation of the positioning post and the positioning groove, but also when the positioning post is inserted into the positioning groove, the second yoke 45 can be pushed towards the second limiting part 172 by the groove wall of the positioning groove, so as to limit the coil driving part 40 in the Y direction.
[0060] Therefore, in this embodiment, with the cooperation of the positioning post and the positioning groove, and the simultaneous limiting of the second yoke 45 by the second limiting part 172, the limiting of the coil driving part 40 along the X and Y directions is achieved.
[0061] Please see Figure 8 In one embodiment of this utility model, in order to ensure the installation stability of the coil driving part 40, the base 10 further includes a first limiting block 18. The first limiting block 18 and the first limiting part 171 are arranged opposite to each other and are used to clamp the first connecting part 452. Thus, when the coil driving part 40 is pushed into place on the main body 11, the first connecting part 452 of the second yoke 45 is clamped between the first limiting part 171 and the first limiting block 124, that is, the second yoke 45 is limited along the Z direction.
[0062] Furthermore, a limiting platform 112 is provided on the inner wall of the main body 11, and the frame 41 abuts against one side of the limiting platform 112 along the Y direction. The limiting platform 112 is provided with the aforementioned first limiting block 18. Since the limiting platform 112 has a certain thickness along the X direction, in order to facilitate the molding of the base 10, a weight reduction groove 1121 is provided on the limiting platform 112. In this way, the thickness of the limiting platform 112 along the X direction is reduced, which facilitates injection molding and ensures the consistency of thickness.
[0063] Please see Figure 3 and Figure 9In one embodiment of this utility model, when the first yoke 44 is installed in a limiting position, the main body 11 is provided with a limiting structure 19, and the second yoke 45 is engaged with the limiting structure 19. In this way, based on the positioning of the positioning post and positioning groove in the X direction and the positioning of the first mating part 453 and the second limiting part 172 in the Y direction, this embodiment can also provide a limiting structure 19 on the base 10. When the coil driving part 40 is inserted into the base 10, the limiting structure 19 limits the first yoke 44, which is equivalent to limiting the installation of the coil driving part 40 in the Z direction. Thus, the coil driving part 40 is limited in the X, Y and Z directions in multiple positions, ensuring the installation stability of the coil driving part 40.
[0064] Specifically, the limiting structure 19 includes a second limiting block 191 and a third limiting block 192 disposed opposite to each other, and a connecting block 193 connecting the second limiting block 191 and the third limiting block 192. A clamping space 194 for the first yoke 44 is formed between the second limiting block 191 and the third limiting block 192. The second limiting block 191 is connected to the bottom wall of the main body 11, and the third limiting block 192 and the connecting block 193 are disposed on the side wall of the main body 11. Thus, the clamping space 194 is formed by the second limiting block 191 and the third limiting block 192, and the structural strength of the main body 11 can be increased by the connecting block 193 and the third limiting block 192 being disposed on the same side wall of the main body 11.
[0065] Furthermore, the first yoke 44 in this embodiment includes a second connecting portion 441, an inclined portion 442, and a second mating portion 443. The second connecting portion 441 is connected to the iron core 43. The inclined portion 442 is set at an obtuse angle to the second connecting portion 441 and the second connecting portion 442, and is inclined in a direction away from the coil 42. The second mating portion 443 is used to engage with the armature portion 50. The inclined portion 442 is locked in the clamping space 194. In this way, by setting the inclined portion 442 in the second yoke 45 and tilting it in a direction away from the coil 42, the movement of the push card 20 can be avoided, so that there is a larger breaking distance between the active contact 314 and the main stationary contact 322, thereby avoiding the influence of sparks when disconnecting, and allowing the main contact portion 30 to be applied to loads with higher voltages.
[0066] Understandably, the second limiting block 191 and the third limiting block 192 are respectively provided with inclined surfaces that are adapted to the inclined angle of the inclined portion 442, so as to clamp on both sides of the inclined portion 442.
[0067] Please refer to Figure 7 and Figure 8In this embodiment, when installing the side plate 12, the first yoke 44 is provided with a first protrusion 444, the second yoke 45 is provided with a second protrusion 454, and the side plate 12 is provided with a first locking hole 121 and a second locking hole 122. The first protrusion 444 and the second protrusion 454 are inserted into the first locking hole 121 and the second locking hole 122 respectively. In this way, the side plate 12 is fixedly installed, that is, the side plate 12 and the first yoke 44 and the second yoke 45 are detachably connected, which facilitates the assembly of the entire relay.
[0068] The side plate 12 is provided with a through hole 123 for the rotating shaft 522 to rotate.
[0069] Furthermore, to ensure the installation stability of the side plate 12, at least one end of the side plate 12 along the Z direction is provided with a pair of locking blocks 124. Each pair of locking blocks 124 forms a clamping groove, and the first yoke 44 and / or the second yoke 45 are locked in the corresponding clamping groove. In this way, not only is the installation of the side plate 12 achieved by locking the first protrusion 444 and / or the second protrusion 454 into the corresponding locking hole, but also by providing locking blocks 124 on the side plate 12, after the first yoke 44 and / or the second yoke 45 are placed in the clamping groove formed by the locking blocks 124, it is equivalent to clamping the locking blocks 124 onto the yoke, which further ensures the stability of the side plate 12 installed on the first yoke 44 and the second yoke 45.
[0070] Understandably, corresponding to the coil drive section 40 including a first yoke 44 and a second yoke 45, the side plate 12 is provided with two pairs of locking blocks 124, one locking block 124 is locked onto a yoke, so as to further ensure the stability of the installation of the side plate 12 and the yoke.
[0071] Please see Figures 1 to 3 , Figure 9 as well as Figure 10 In one embodiment of this utility model, in order to improve the safety of the relay during use, the relay 100, which is easy to install, also includes an arc-extinguishing magnet 80. The arc-extinguishing magnet 80 is installed on the main body 11 along the X direction. Specifically, the main body 11 is provided with a first slot 113 for installing the arc-extinguishing magnet 80. Along the X direction, the arc-extinguishing magnet 80 is located on the side of the active contact structure 31 and the main stationary contact structure 32, and the inner wall of the outer shell 70 is provided with a relief groove 71 for the arc-extinguishing magnet 80, or the inner wall of the outer shell 70 is directly attached to the arc-extinguishing magnet 80. Through the setting of the arc-extinguishing magnet 80, the arc generated when the main stationary contact 322 and the active contact 314 are disconnected can be extinguished, thereby improving the safety of use.
[0072] In one embodiment, when installing the arc-extinguishing magnet 80, a first slot 113 may be provided on the main body 11, and a matching second slot may be provided on the outer shell 70. Part of the arc-extinguishing magnet 80 is inserted into the first slot 113, and the other part is inserted into the second slot, thereby realizing the installation of the arc-extinguishing magnet 80.
