Description

Technical Field

[0001] The present application relates to the field of contactor assembly auxiliary devices, and in particular to a contactor assembly jig. Background Art

[0002] A contactor is a widely used switching device that uses electromagnetic, pneumatic, or hydraulic principles to control circuits and switch the main circuit on and off. Contactors offer advantages such as strong current-interrupting capability, rapid operation, and safe operation.

[0003] The relevant contactor includes an arc-isolating cover, a contact switch, a moving rod, a moving magnetic core and a moving electrode plate. The contact switch is clamped in the arc-isolating cover, the moving rod is slidably connected in the arc-isolating cover, the lower end of the moving rod is connected to the moving magnetic core, the upper end is connected to the moving electrode plate, and the middle part of the moving rod is connected to the auxiliary synchronization bracket. When the contactor is installed in the circuit, when an abnormal situation occurs in the circuit, the electromagnetic coil generates an electromagnetic field and attracts the moving magnetic core, causing the moving rod to be moved by the magnetic force. When the moving rod slides, it drives the auxiliary synchronization bracket and the moving electrode plate to slide, so that the auxiliary synchronization bracket contacts the contact switch, thereby achieving the effect of improving electricity safety.

[0004] The above-mentioned related technical solutions have the following defects: threads are provided at both ends of the moving rod and are respectively connected to the moving magnetic core and the moving electrode plate. When assembling the contactor, the distance between the moving magnetic core and the moving electrode plate is difficult to accurately control, which affects the subsequent assembly and product quality and causes inconvenience. Utility Model Content

[0005] In order to improve the installation accuracy of the moving electrode plate on the moving rod, the present application provides a contactor assembly jig.

[0006] The contactor assembly jig provided in this application adopts the following technical solution:

[0007] A contactor assembly jig includes a fixed base and a support plate. The support plate is arranged on the upper surface of the fixed base, and the fixed base is arranged horizontally. When the arc shield of the contactor is arranged on the fixed base, the moving rod is perpendicular to the fixed base, the moving magnetic core at the lower end of the moving rod is clamped on the lower bottom surface of the fixed base, and the moving electrode plate is clamped on the upper surface of the support plate.

[0008] By adopting the above technical solution, a support plate is provided on the fixed seat, so that the arc shield of the contactor can be placed on the fixed seat, the moving rod is located on the outside of the fixed seat, the lower end of the moving rod is threadedly connected to the moving magnetic core, and the moving magnetic core is stuck on the lower bottom surface of the fixed seat. When the user installs the moving motor plate, it is necessary to insert the upper end of the moving rod into the through hole in the middle of the moving motor plate and set a nut on the moving rod. During the process of screwing the nut, the distance between the moving electrode plate and the moving magnetic core gradually decreases until the moving electrode plate abuts against the support plate. When the moving magnetic core is stuck on the lower bottom surface of the fixed seat and the moving electrode plate is stuck on the upper surface of the support plate, the nut cannot be screwed any further, and the position of the moving electrode plate remains fixed, so that the moving electrode plate can be installed to the predetermined position. After the installation is completed, the user screws the moving magnetic core so that the contactor can be removed from the fixed seat and other installation work can be performed, thereby improving the installation efficiency and production quality of the contactor.

[0009] Optionally, a plurality of screws are provided on the support plate, and the screws pass through the support plate and are threadedly connected to the fixing seat.

[0010] By adopting the above technical solution, screws are set on the support plate so that the fixing seat and the support plate can be detachably connected. The user can set support plates of different heights on the fixing seat, thereby making it possible to adjust the distance between the moving electrode plate and the moving magnetic core when assembling the contactor, making it convenient for the user to assemble contactors of different models.

[0011] Optionally, a plurality of countersunk holes are provided on the support plate, and the screw rod heads are arranged in the countersunk holes.

[0012] By adopting the above technical solution, a countersunk hole is opened on the support plate. When the screw is inserted into the countersunk hole, the column head of the screw can be set in the countersunk hole, thereby making the surface of the support plate flat. When the moving electrode plate cover is set on the support plate, the distance between the moving electrode plate and the moving magnetic core meets the installation standard.

[0013] Optionally, a washer is provided between the fixing seat and the supporting plate, and the screw rod passes through the washer and is connected to the fixing seat.

[0014] By adopting the above technical solution, a washer is set between the fixed seat and the support plate, so that the washer is stuck between the fixed seat and the support plate, which makes it convenient for users to adjust the distance between the support plate and the fixed seat. The user installs washers of different heights on the screw, thereby achieving the effect of adjusting the distance between the support plate and the fixed seat, which is convenient for use.

[0015] Optionally, the support plate includes a connecting portion and a supporting portion, the countersunk hole is provided on the connecting portion, and the supporting portion is used to be clamped on the moving electrode plate.

[0016] By adopting the above technical solution, by arranging the connecting part and the supporting part on the supporting plate, the lower part of the supporting part is suspended in the air, and the arc shield can be arranged on the lower side of the supporting part, thereby achieving the effect of streamlining the fixture structure.

[0017] Optionally, a clamping groove is provided on the side wall of the fixing seat, and the clamping groove is used to clamp with the moving rod.

[0018] By adopting the above technical solution, a clamping groove is opened so that the moving rod can be vertically inserted into the clamping groove, so that the clamping groove has a limiting effect, reducing the chance of the moving rod being skewed, and making the moving rod vertical relative to the fixed seat. When the moving magnetic core is clamped on the lower side of the fixed seat and the moving electrode plate is covered on the support plate, the moving rod remains vertical, and the position of the moving electrode plate on the moving rod is accurate. After the assembly is completed, the user screws the moving magnetic core to move the moving magnetic core in the direction away from the moving electrode plate, thereby disengaging the moving magnetic core from the fixed seat and the moving electrode plate from the support plate. The user can remove the contactor from the jig by moving the contactor horizontally, which is convenient for use.

[0019] Optionally, the number of the supporting plates is two, and the two supporting plates are respectively located on both sides of the clamping slot.

[0020] By adopting the above technical solution, by arranging support plates on both sides of the clamping groove, the support plates can be respectively clamped on the two ends of the moving electrode plate, so that the moving electrode plate can be kept horizontal on the support plates, and then the moving electrode plate is always perpendicular to the moving rod, and the installation position accuracy is high.

[0021] Optionally, the upper surface and the lower surface of the fixing seat are flat and parallel to each other, and the upper surface of the supporting plate is parallel to the upper surface of the fixing seat.

[0022] By adopting the above technical solution, by opening the upper and lower surfaces of the fixed seat into horizontal planes, when the arc shield is placed on the upper surface of the fixed seat and the moving magnetic core is stuck on the lower surface of the fixed seat, the support and limiting accuracy of the fixed seat is better. When the moving electrode plate abuts against the support plate and cannot continue to fall, it means that the distance between the moving electrode plate and the moving magnetic core is equal to the overall height of the support plate and the fixed seat.

[0023] In summary, the beneficial technical effects of this application are:

By arranging a supporting plate on the fixing seat, the arc shield of the contactor can be placed on the fixing seat, the moving rod is located outside the fixing seat, the lower end of the moving rod is threadedly connected to the moving magnetic core, and the moving magnetic core is stuck on the lower bottom surface of the fixing seat. When the user installs the moving motor plate, it is necessary to insert the upper end of the moving rod into the through hole in the middle of the moving motor plate and set a nut on the moving rod. During the process of screwing the nut, the distance between the moving electrode plate and the moving magnetic core gradually decreases until the moving electrode plate abuts against the supporting plate. When the moving magnetic core is stuck on the lower bottom surface of the fixing seat and the moving electrode plate is stuck on the upper surface of the supporting plate, the nut cannot be screwed any further, and the position of the moving electrode plate remains fixed, so that the moving electrode plate can be installed to the predetermined position. After the installation is completed, the user screws the moving magnetic core so that the contactor can be removed from the fixing seat and other installation work can be carried out, thereby improving the installation efficiency and production quality of the contactor;

[0025] 2. By setting screws on the support plate, the fixing base and the support plate are detachably connected. Users can set support plates of different heights on the fixing base, thereby adjusting the distance between the moving electrode plate and the moving magnetic core during contactor assembly, making it easier for users to assemble different types of contactors.

[0026] 3. By opening a snap-fit ​​groove, the movable rod is vertically inserted into the snap-fit ​​groove, so that the snap-fit ​​groove has a limiting effect, reducing the chance of the movable rod being skewed, and making the movable rod vertical relative to the fixed seat. When the moving magnetic core is stuck on the lower side of the fixed seat and the moving electrode plate is covered on the support plate, the movable rod remains vertical, and the position of the moving electrode plate on the movable rod is accurate. After the assembly is completed, the user screws the moving magnetic core to move the moving magnetic core away from the moving electrode plate, thereby disengaging the moving magnetic core from the fixed seat and the moving electrode plate from the support plate. The user can remove the contactor from the jig by moving the contactor horizontally, which is convenient for use. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0033] The present application is further described in detail below with reference to the accompanying drawings.

[0034] The present application embodiment discloses a contactor assembly jig, referring to Figure 1 、 Figure 2 and Figure 3, including a fixed base 1 and a supporting plate 2. The fixed base 1 is set horizontally, and the supporting plate 2 is set on the upper surface of the fixed base 1. The upper and lower surfaces of the fixed base 1 are both set as horizontal planes. The fixed base 1 is used to place the arc shield 51 of the contactor 5, and the supporting plate 2 is used to support the moving electrode plate 55 of the contactor 5. The contactor 5 includes the arc shield 51, the contact switch 52, the moving rod 53, the moving magnetic core 54, the moving electrode plate 55 and the auxiliary synchronization bracket 56. The contact switch 52 is fixed in the arc shield 51, and the moving rod 53 is slidably connected in the arc shield 51. When the arc shield 51 is placed on the upper surface of the fixed base 1, the moving rod 53 is set vertically and slides in the vertical direction. The moving magnetic core 54 is connected to the lower end of the moving rod 53. The lower end of the moving rod 53 is threaded. The moving magnetic core 54 is a cylindrical structure and is threadedly connected to the moving rod 53. The moving magnetic core 54 is connected to the upper end of the moving rod 53. When assembling the contactor 5, the moving electrode plate 55 needs to be installed on the upper end of the moving rod 53. The upper end of the moving rod 53 is provided with an external thread, and the middle part of the moving electrode plate 55 is provided with a through hole. The user needs to insert the moving rod 53 into the through hole in the middle part of the moving electrode plate 55, and connect the moving electrode plate 55 to the moving rod 53 by installing a nut on the moving rod 53.

[0035] Reference Figure 2 、 Figure 3 and Figure 4 During the assembly of the contactor 5, the distance between the moving electrode plate 55 and the moving magnetic core 54 is difficult to control. The position of the nut on the moving rod 53 affects the position of the moving electrode plate 55, thereby affecting the subsequent installation efficiency and the production quality of the contactor 5. When assembling the contactor 5, the arc shield 51 is placed on the upper surface of the fixed seat 1, the moving rod 53 is set vertically, the lower end of the moving rod 53 is connected to the moving magnetic core 54, and the moving magnetic core 54 is clamped on the lower surface of the fixed seat 1. At this time, the moving electrode plate 55 is connected to the moving rod 53 and the nut is screwed. This can make the moving electrode plate 55 cover the support plate 2, thereby keeping the distance between the moving electrode plate 55 and the moving magnetic core 54 constant, so that the dimensional accuracy of the assembled contactor 5 is high. When the moving electrode plate 55 is clamped on the upper surface of the support plate 2 and the moving magnetic core 54 is clamped on the lower bottom surface of the fixed seat 1, it means that the installation of the contactor 5 meets the requirements. The user can remove the contactor 5 from the fixed seat 1 by screwing the moving magnetic core 54, completing the installation of the moving electrode plate 55.

[0036] Reference Figure 1 A screw 3 is provided between the fixing base 1 and the support plate 2. The screw 3 passes through the support plate 2 and is threadedly connected to the fixing base 1. The fixing base 1 and the support plate 2 are detachably connected. The user can install support plates 2 of different heights on the fixing base 1 according to the size parameters of the contactor 5 produced, thereby achieving a positioning effect for contactors 5 of different sizes.

[0037] Reference Figure 1 and Figure 5A washer 4 is provided between the fixing base 1 and the support plate 2. The washer 4 is a cylindrical structure with a mounting hole 41 defined at the center thereof. The screw 3 is inserted into the mounting hole 41. The screw 3 penetrates the support plate 2 and the washer 4 and is threadedly connected to the fixing base 1. The washer 4 is used to support the support plate 2, creating a gap between the support plate 2 and the fixing base 1 to facilitate the installation of the irregularly shaped arc shield 51 on the fixing base 1.

[0038] Reference Figure 1 The support plate 2 includes a connecting portion 21 and a supporting portion 22. The connecting portion 21 has a countersunk hole 211, into which the head of the screw 3 is disposed. This creates a smooth upper surface for the support plate 2 and reduces the chance of the head of the screw 3 getting stuck on the underside of the moving electrode plate 55. The supporting portion 22 is connected to the connecting portion 21 and extends horizontally to hold the moving electrode plate 55. The arc shield 51 has a complex shape and is positioned in the space below the supporting portion 22, allowing it to abut against the fixing base 1.

[0039] Reference Figure 1 The fixing base 1 is provided with a snap-fitting groove 11, which is formed on a side wall of the fixing base 1. When the arc shield 51 is placed on the fixing base 1, the movable rod 53 is located in the snap-fitting groove 11. The movable rod 53 slides vertically within the snap-fitting groove 11, thereby making the snap-fitting groove 11 act as a limiter. After the movable electrode plate 55 is installed, the user can loosen the contactor 5 on the fixing base 1 by twisting the movable magnetic core 54. The contactor 5 can then be removed without removing the movable magnetic core 54 from the movable rod 53.

[0040] Reference Figure 1 There are two support plates 2, and the two support plates 2 are respectively arranged on both sides of the clamping groove 11. When the movable electrode plate 55 is installed on the movable rod 53, the movable rod 53 is located between the two support plates 2, and the two ends of the movable electrode plate 55 are respectively covered on the two support plates 2.

[0041] The implementation principle of the embodiment of the present application is: by arranging a support plate 2 on the fixed seat 1, the support plate 2 can be clamped on the moving electrode plate 55. During the installation of the contactor 5, the position of the moving magnetic core 54 at one end of the moving rod 53 is relatively fixed, and the position of the moving electrode plate 55 at the other end is determined by the nut. There is adjustment space between the moving electrode plate 55 and the moving magnetic core 54. By arranging the arc isolation cover 51 on the fixed seat 1, the moving electrode plate 55 can be clamped on the support plate 2, and the moving magnetic core 54 can be clamped on the lower bottom surface of the fixed seat 1, thereby facilitating the positioning of the moving electrode plate 55, and making the position of the moving electrode plate 55 more accurate when producing and installing the contactor 5.

[0042] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
