Description

Technical Field

[0001] The utility model relates to the technical field of contactors, in particular to an anti-electricity shaking AC contactor. Background Art

[0002] AC contactors often use three arc extinguishing methods: double-break electric arc extinguishing, longitudinal seam arc extinguishing and grid arc extinguishing to eliminate the arc generated by the moving and static contacts during the opening and closing process. The working principle of the AC contactor is to use electromagnetic force in conjunction with spring elastic force to achieve the connection and disconnection of the contacts.

[0003] Existing AC contactors are generally installed on cabinets, but if the equipment in the cabinet vibrates, the AC contactors will shake, which will affect the stability of the wiring in the long run, resulting in poor contact and easily causing failures. Utility Model Content

[0004] The utility model aims to solve one of the technical problems existing in the prior art or related technology.

[0005] To this end, the technical solution adopted in this utility model is:

[0006] An anti-electrical shaking AC contactor comprises: a contactor assembly and a fixing assembly; wherein the contactor assembly comprises a main body and a wiring terminal mounted on the main body; the fixing assembly is arranged on the main body, and the fixing assembly comprises mounting blocks fixed to both ends of the main body, screw holes opened on the mounting blocks, threaded rods threadedly connected to the screw holes, a hinge shaft fixed to the outer ends of the threaded rods, a clamping plate fixed to the hinge shaft, a fixing groove opened on the inner side of the clamping plate, an anti-slip pad fixed in the fixing groove, a slide rail fixed to the end of the clamping plate, and a fixing sleeve assembled on the slide rail.

[0007] In a preferred example, the utility model can be further configured as follows: a support bar is fixed to the back side of the main body, and a cushioning strip is connected to the support bar.

[0008] In a preferred example, the utility model can be further configured as follows: the pad protection strip is arranged in an eight-shaped shape.

[0009] In a preferred example, the present invention can be further configured as follows: the mounting block is centrally arranged at the end of the main body.

[0010] In a preferred example, the utility model can be further configured as follows: a sliding block clamped in the sliding rail is connected inside the fixing sleeve.

[0011] In a preferred example, the utility model can be further configured as follows: a rubber block is fixed on the inner side of the fixing sleeve, and a positioning groove adapted to the rubber block is provided on the clamping plate.

[0012] The above technical solution of the utility model has the following beneficial technical effects:

[0013] The utility model can fix the cables on the wiring terminals in the fixing grooves by means of fixing components using a clamping plate, so that the main body is connected between the cables instead of being installed on the cabinet. The support strips and the padding strips are used to pad the main body so as to contact the cabinet, thereby providing stability and greatly improving the anti-swaying ability of the main body. The reduced shaking force does not affect the stability of the wiring between the cables and the wiring terminals, and the utility model has high practicality. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings. It should be noted that the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict.

[0021] An anti-electricity shaking AC contactor provided by some embodiments of the utility model is described below in conjunction with the accompanying drawings.

[0022] Combination Figure 1-3 As shown, the utility model provides an anti-power-sway AC contactor, comprising: a contactor assembly 100 and a fixing assembly 200 ; wherein the contactor assembly 100 comprises a main body 110 and a connection terminal 120 mounted on the main body 110 .

[0023] Specifically, a support bar 111 is fixed to the back of the main body 110, and a pad protection bar 112 is connected to the support bar 111. The pad protection bar 112 is arranged in an eight-shape. The support bar 111 and the pad protection bar 112 can prevent a gap from being generated between the main body 110 and the cabinet, thereby causing a certain amount of shaking. The support bar 111 and the pad protection bar 112 can not only avoid the generation of gaps, but also play a shock-absorbing and buffering role, thereby achieving an anti-sway effect.

[0024] The fixing assembly 200 is disposed on the main body 110, and the fixing assembly 200 includes a mounting block 210 fixed to both ends of the main body 110, a screw hole 220 provided on the mounting block 210, a threaded rod 230 threadedly connected to the screw hole 220, a hinge shaft 240 fixed to the outer end of the threaded rod 230, a clamping plate 250 fixed to the hinge shaft 240, a fixing groove 260 provided on the inner side of the clamping plate 250, an anti-slip pad 270 fixed in the fixing groove 260, and a clamping plate 250 fixed to the clamping plate 250. 0 end and the fixing sleeve 290 assembled on the sliding rail 280, the cable on the terminal block 120 can be fixed in the fixing groove 260 by using the clamping plate 250 through the fixing assembly 200, so that the main body 110 is connected between the cables instead of being installed on the cabinet, and the main body 110 is in contact with the cabinet with the support strip 111 and the pad protection strip 112, which provides stability and greatly improves the anti-sway ability of the main body 110, and the reduced shaking force does not affect the stability of the connection between the cable and the terminal block 120, and the practicality is high.

[0025] Specifically, the mounting block 210 is centrally disposed at the end of the main body 110, so that the clamping plate 250 can be clamped on the cable located in the middle, thereby improving the stability of the main body 110. Of course, two sets of fixing components 200 can also be disposed to clamp the cables located on both sides, which is more practical.

[0026] Furthermore, the fixing sleeve 290 is connected to a slider 291 mounted in the slide rail 280. After the clamping plates 250 are combined, the fixing sleeve 290 can be slid on the slide rail 280, so that the fixing sleeve 290 is sleeved on the end of the clamping plate 250 to play a fixing role.

[0027] On the other hand, a rubber block 292 is fixed to the inner side of the fixing sleeve 290 , and a positioning groove 293 adapted to the rubber block 292 is opened on the clamping plate 250 , which can play a stabilizing role after the fixing sleeve 290 is put on the clamping plate 250 and prevent the fixing sleeve 290 from slipping off the end of the clamping plate 250 .

[0028] The working principle and use process of the utility model are as follows: first, insert the threaded rod 230 into the screw hole 220, rotate the clamping plate 250 to adjust to a suitable position, and then connect the cable to the terminal block 120. At this time, the cable is located on the inner side of the fixing groove 260, and then merge the clamping plate 250 inward, and use the clamping plate 250 to fix the cable. Finally, push the fixing sleeve 290 to slide on the slide rail 280, so that the fixing sleeve 290 is sleeved on the end of the clamping plate 250 to complete the fixation. In this way, the main body 110 is fixed between the two sections of the cable. At this time, the pad protection strip 112 on the support strip 111 can be pressed against the cabinet.

[0029] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
