Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of static contacts, and particularly relates to a static contact structure. Background Art
[0002] In a circuit, a static contact generally cooperates with a moving contact. The static contact is fixedly installed, and the moving contact is movably installed. By moving the moving contact, it contacts or separates from the contact on the static contact, thereby realizing the connection or disconnection of the circuit. Most of the contacts on the existing static contacts are fixed by welding. After the static contact is fixedly installed, the contact cannot move. If the installation position of the static contact is offset or the contact is welded crooked, the moving contact and the contact on the static contact will be misaligned, affecting the use of the circuit. Usually, the static contact needs to be removed and reinstalled by drilling holes, and the operation is rather troublesome. Content of the Utility Model
[0003] The purpose of the utility model is to provide a static contact structure to solve the problem that the position of the contact on the existing static contact structure cannot be adjusted.
[0004] To achieve the above purpose, the utility model provides the following technical solutions:
[0005] A static contact structure includes a mounting base and a fixed base fixedly connected to one side of the mounting base. A U-shaped slide base is slidably connected to one side of the fixed base. A slide frame is slidably connected to the middle of the slide base. The two ends of the slide base respectively extend into the fixed base, and fixing plates are fixedly installed on the two ends of the slide base. Fixing components are arranged on the two fixing plates, and a contact is fixedly installed on the slide frame.
[0006] Preferably, it further includes a mounting hole and a wiring hole opened on the mounting base.
[0007] Preferably, a guide groove is opened on the slide base, one end of the slide frame is slidably connected in the guide groove, and a guide rod fixedly installed in the guide groove and slidably penetrating the slide frame is provided.
[0008] Preferably, the fixing component includes a threaded hole opened on the fixing plate and a fixing bolt screwed into the threaded hole.
[0009] Preferably, an arcing plate is slidably connected to the fixed base. A plurality of tooth-shaped blocks are fixedly installed at one end of the slide frame, and a tooth-shaped groove cooperating with the plurality of tooth-shaped blocks is arranged on one side of the arcing plate.
[0010] Preferably, ear seats are fixedly provided on both sides of the arcing plate. Through holes are opened on the two ear seats. Two through grooves are opened on the fixed base. The bottom end of each fixing bolt sequentially passes through the through hole on the ear seat, the through groove and the threaded hole on the fixing plate from top to bottom, and the diameter of the head of the fixing bolt is larger than the width of the through hole on the ear seat.
[0011] Compared with the prior art, the utility model has the following beneficial effects:
[0012] (1) The utility model is provided with a sliding seat and a sliding frame. By sliding the sliding seat in the fixed seat and sliding the sliding frame in the sliding seat, the sliding frame can drive the contact to move in a plane, so that the position of the contact can be flexibly adjusted even after the mounting seat is fixedly installed, and when the contact is misaligned, it is not necessary to disassemble the static contact structure as a whole, the operation is simple, and the installation efficiency is improved.
[0013] (2) The utility model is provided with a toothed block, a toothed groove and a fixing component. The fixing bolt in the fixing component passes through the through hole on the ear seat and the through groove on the fixed seat and is screwed into the threaded hole on the fixing plate, so that the ear seat and the fixing plate clamp the fixed seat. At this time, the toothed block at the end of the sliding frame is engaged with the toothed groove on the arc ignition plate to prevent the sliding frame from sliding on the sliding seat. At the same time, the sliding seat is relatively fixed to the fixed seat, and further the contact is relatively fixed to the fixed seat, so as to realize the fixation of the contact, avoid the influence of the shaking of the contact on the use of the circuit during the use process, and thus it is convenient to limit the two moving directions of the contact only by the fixing bolt.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts belong to the scope of protection of the present utility model.
[0020] Please refer to Figures 1 - 4 shown, the present utility model provides the following technical solutions:
[0021] A static contact structure includes a mounting base 1 and a fixed base 2 fixedly connected to one side of the mounting base 1. A U-shaped slide base 6 is slidably connected to one side of the fixed base 2. A slide frame 5 is slidably connected to the middle of the slide base 6. Two ends of the slide base 6 respectively extend into the fixed base 2, and fixing plates 10 are fixedly installed on both ends of the slide base 6. Fixing components are provided on both fixing plates 10, and a contact 4 is fixedly installed on the slide frame 5;
[0022] It further includes a mounting hole 14 and a wiring hole 15 opened on the mounting base 1;
[0023] A guide groove 7 is opened on the slide base 6. One end of the slide frame 5 is slidably connected in the guide groove 7, and a guide rod 8 that slidably penetrates the slide frame 5 is fixedly installed in the guide groove 7.
[0024] Based on the above disclosed structure, when installing the static contact structure:
[0025] First, use screws and other connecting parts through the mounting hole 14 on the mounting base 1 to install the static contact structure at the position to be installed. Then, adjust the position of the contact 4 in the static contact structure according to the position of the contact on the external moving moving contact, and it is necessary to ensure that the contact 4 will not be misaligned when the circuit is conducting, affecting the use of the circuit. The specific operation is as follows: As Figure 1 shown, when the contact 4 moves left and right, slide the slide base 6 so that the two ends of the slide base 6 extend into or slide out of the fixed base 2, thereby making the middle of the slide base 6 move left and right, and further making the slide frame 5 drive the contact 4 to move left and right; when the contact 4 moves forward and backward, slide the slide frame 5 on the slide base 6 so that the end of the slide frame 5 slides along the guide rod 8 in the guide groove 7, thereby driving the contact 4 to move forward and backward. In this way, the position of the contact 4 can be flexibly adjusted, and then the contact 4 is fixed through the fixing component;
[0026] Then connect the end of the external wire to the wiring hole 15 on the mounting base 1 by means of twisting or welding to conduct, thereby completing the installation of the static contact.
[0027] Regarding the above fixing component, preferably, the following structure is provided:
[0028] The fixing component includes a threaded hole opened on the fixing plate 10 and a fixing bolt 12 screwed into the threaded hole;
[0029] An arc guide plate 3 is slidably connected to the fixed base 2. One end of the slide frame 5 is fixedly installed with a plurality of toothed blocks 16, and a toothed groove 9 that cooperates with the plurality of toothed blocks 16 is provided on one side of the arc guide plate 3;
[0030] Arc striking plates 3 are fixedly provided with ear seats 11 on both sides. Through holes are formed in the two ear seats 11. Two through slots 13 are formed in the fixed seat 2. The bottom end of each fixing bolt 12 sequentially passes through the through hole in the ear seat 11, the through slot 13 and the threaded hole in the fixing plate 10 from top to bottom, and the diameter of the head of the fixing bolt 12 is larger than the width of the through hole in the ear seat 11.
[0031] As can be seen from the above, when fixing the fixed contact 4, the sliding arc striking plate 3 makes the toothed grooves 9 on the arc striking plate 3 abut against a plurality of toothed blocks 16 at the end of the carriage 5, so as to limit the sliding of the carriage 5 in the guide slot 7 on the slide base 6 through the toothed grooves 9 and the toothed blocks 16. At this time, the through holes on the ear seats 11 on both sides of the arc striking plate 3 are directly above the threaded holes on the two fixing plates 10. At this time, the two fixing bolts 12 are respectively inserted upward from the upper directions of the two ear seats 11, so that the fixing bolts 12 sequentially pass through the through holes in the ear seats 11 and the through slots 13 in the fixed seat 2, and then are screwed into the threaded holes in the fixing plate 10. Continue to rotate the fixing bolts 12 to gradually screw the fixing bolts 12 into the threaded holes until the heads of the fixing bolts 12 abut against the tops of the ear seats 11. And because the diameter of the heads of the fixing bolts 12 is larger than the width of the through holes in the ear seats 11, the heads of the fixing bolts 12 press down the ear seats 11, so that the ear seats 11 clamp the fixed seat 2 on both sides of the through slot 13, so that the slide base 6 and the arc striking plate 3 are relatively fixed to the fixed seat 2. The fixation of the slide base 6 restricts the left and right movement of the contact 4, and the fixation of the arc striking plate 3 restricts the front and back movement of the contact 4, so as to realize the fixation of the contact 4, and only the fixing bolts 12 can limit the two moving directions of the contact, with simple operation and high efficiency.
