DETAILED DESCRIPTION

[0035] In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application.

In addition, the terms "first", "second" and the like are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0039] In the description of the present application, it should be noted that, unless otherwise explicitly specified and limited, the terms "set", "connected" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be directly connected, or indirectly connected through an intermediate medium, or it can be connected inside two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0040] In low-voltage electrical appliances such as contactors or relays, components such as movable contact bridges and static contacts are usually included. During the operation of the contactor, the contact bridge moves and contacts two static contacts at different positions to realize the closing of the contactor.

[0041] The prior art adopts a form in which two contact bridges are arranged side by side, but this form requires the two contact bridges to be assembled into a whole before being assembled to the contact head support of the contactor, which is complex and results in low assembly efficiency.

[0042] Based on this, the embodiments of the present application provide a contact bridge and a contactor, which can simplify the assembly method of the contact bridge, improve the assembly efficiency of the contact bridge to the contactor under the premise of ensuring the reliability of closing, and thus improve the overall assembly efficiency of the contactor.

[0043] In order for those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings.

[0044] Please refer to Figures 1 to 3 The present embodiment provides a contact bridge 1, which comprises a main body part 11, at least two first connecting parts 12 are arranged at the first end of the main body part 11, at least two second connecting parts 13 are arranged at the second end of the main body part 11, and at least four connecting channels are formed between the first end and the second end.

[0045] By arranging at least two first connecting portions 12 and at least two second connecting portions 13 on the main body 11, at least four paths can be formed on the contact bridge 1, so that the contact bridge 1 can still be kept on when one of the paths fails, ensuring the reliability of the contact bridge 1. Moreover, the arrangement avoids the problem of complicated assembly operation caused by arranging multiple contact bridges 1, effectively improving the assembly efficiency of the contact bridge 1 in the contactor.

[0046] Specifically, the first end and the second end are two opposite positions on the main body 11, the first connecting portion 12 is arranged at the first end, and the second connecting portion 13 is arranged at the second end. The first connecting portion 12 and the second connecting portion 13 are connected in communication through the main body 11. The main body 11, the first connecting portion 12 and the second connecting portion 13 are arranged in an integrated structure, which is formed in one piece. On the one hand, it is convenient for production and processing, and on the other hand, it is convenient for overall rapid assembly into the contactor, so as to simplify the installation process of the contact bridge 1, thereby improving the installation efficiency.

[0047] In the embodiment, referring to Figure 2 and Figure 3 , two first connecting portions 12 and two second connecting portions 13 are arranged. One of the first connecting portions 12 can form a connecting path with the two second connecting portions 13, such as the first path A and the second path B. The other first connecting portion 12 can also form a connecting path with the two second connecting portions 13, such as the third path C and the fourth path D. In this way, four connecting paths can be formed on the contact bridge 1, and at least one connecting path can be used when one, two or even three connecting paths fail.

[0048] In an alternative embodiment, the first connecting portion 12 can be provided with more than two, and the second connecting portion 13 can also be provided with more than two. More first connecting portions 12 and second connecting portions 13 can be combined to form more connecting paths, which is conducive to improving the contact performance of the contact bridge 1.

[0049] Referring to Figures 1 to 4 , the application further provides a contactor comprising a contact support 2 and the above-mentioned contact bridge 1. The contact bridge 1 is installed on the contact support 2. The contact support 2 is provided with a first static contact 21 and a second static contact 22. The at least two first connecting portions 12 correspondingly abut against the first static contact 21, and the at least two second connecting portions 13 correspondingly abut against the second static contact 22.

[0050] By arranging at least two first connecting portions 12 and at least two second connecting portions 13 on the main body 11, at least four paths can be formed on the contact bridge 1, so that the contact bridge 1 can still be kept on when one of the paths fails, ensuring the reliability of the contact bridge 1. Moreover, the arrangement avoids the problem of complicated assembly operation caused by arranging multiple contact bridges 1, effectively improving the assembly efficiency of the contact bridge 1 in the contactor.

[0051] The contact support 2 can support and limit the installation of the contact bridge 1. The contact bridge 1 can move relative to the contact support 2, and the first static contact 21 and the second static contact 22 are fixedly installed on the contact support 2. The position of the first connecting portion 12 corresponds to the position of the first static contact 21, and the position of the second connecting portion 13 corresponds to the position of the second static contact 22. The contact bridge 1 can contact the first static contact 21 and the second static contact 22 during movement to achieve connection.

[0052] Referring to Figure 2 In some examples, the at least two first connecting portions 12 are arranged at intervals on the first end, and the at least two second connecting portions 13 are arranged at intervals on the second end.

[0053] Arranging the at least two first connecting portions 12 at intervals can reduce the mutual interference between adjacent two first connecting portions 12. Similarly, arranging the at least two second connecting portions 13 at intervals can reduce the mutual interference between adjacent two second connecting portions 13.

[0054] Specifically, among the two first connecting portions 12, when there is rust or foreign matter between one of the first connecting portions 12 and the first static contact 21, the first connecting portion 12 cannot contact the first static contact 21. In this case, another first connecting portion 12 arranged at intervals with the first connecting portion 12 can be unaffected and contact the first static contact 21, thereby achieving the connection function. The same technical effect is achieved by arranging adjacent two second connecting portions 13 at intervals, which will not be described here.

[0055] Referring to Figure 5 In some examples, the first connecting portion 12 is provided with a first contact point 121, and the second connecting portion 13 is provided with a second contact point 14. The first contact point 121 and the second contact point 14 are located on the same side of the contact bridge 1.

[0056] Arranging the first contact point 121 and the second contact point 14 on the same side of the contact bridge 1 facilitates contacting the first static contact 21 and the second static contact 22 on the same side of the contact bridge 1 to achieve connection. Moreover, it can ensure that multiple first connecting portions 12 can simultaneously contact the first static contact 21, and multiple second connecting portions 13 can simultaneously contact the second static contact 22.

[0057] The first contact point 121 is arranged at an end of the first connecting portion 12 away from the main body portion 11, and the second contact point 14 is arranged at an end of the second connecting portion 13 away from the main body portion 11. Both the first contact point 121 and the second contact point 14 are located on the side of the contact bridge 1 facing the first static contact 21 and the second static contact 22.

[0058] Referring to Figure 1 and Figure 5The side of the first static contact 21 facing the contact bridge 1 can be provided with a third contact 211 corresponding to the first contact 121, and the third contact 211 has a larger size so that the first contacts 121 on the plurality of first connecting portions 12 can simultaneously contact the third contact 211. The side of the second static contact 22 facing the contact bridge 1 can be provided with a fourth contact 221 corresponding to the second contact 14, and the fourth contact 221 also has a size larger than the second contact 14 so that the second contacts 14 on the plurality of second connecting portions 13 can simultaneously contact the fourth contact 221.

[0059] Referring to Figure 2 In some examples, the main body portion 11 is provided with a positioning structure 111 on the side of the contact bridge 1 away from the side provided with the first contact 121 and the second contact 14.

[0060] The positioning structure 111 can be used for positioning and installing the contact bridge 1 on the contact support 2, or for positioning a structure connected to the contact bridge 1 to drive the contact bridge 1 to move, and has strong functions and does not affect the overall structure of the contact bridge 1.

[0061] The positioning structure 111 is provided on the side of the contact bridge 1 away from the side provided with the first contact 121 and the second contact 14, i.e., on the side of the contact bridge 1 away from the first static contact 21 and the second static contact 22. When the positioning structure 111 is used to connect a structure to drive the contact bridge 1 to move, the contact bridge 1 can be conveniently moved closer to or farther away from the first static contact 21 and the second static contact 22.

[0062] Referring to Figure 2 and Figure 4 In some examples, the contact support 2 is provided with an assembly hole 23, and the assembly hole 23 is provided with an elastic member 24 corresponding to the positioning structure 111.

[0063] By providing the elastic member 24 in the assembly hole 23 and connecting the elastic member 24 to the positioning structure 111 of the contact bridge 1, the elastic member 24 can be used to limit or drive the contact bridge 1 by the elastic force of the elastic member 24, so that the contact bridge 1 can be moved closer to or farther away from the first static contact 21 and the second static contact 22 to achieve the function of controlling the on-off of the contactor.

[0064] The contact bridge 1 is installed in the assembly hole 23, and the positioning structure 111 is located in the assembly hole 23. The elastic member 24 is positioned and installed in the assembly hole 23 through the positioning structure 111, and the elastic member 24 and the wall of the assembly hole 23 are used to drive and limit the contact bridge 1.

[0065] In the embodiment, the elastic member 24 is provided as a spring, the first end of the spring can abut against the hole wall of the assembly hole 23, and the second end of the spring can abut against the contact bridge 1, so that the contact bridge 1 can be driven to act by the elastic force of the spring itself. Of course, the elastic member 24 can also be provided as a spring washer or a spring leaf and the like elastic component, which can achieve the same technical effect.

[0066] With reference to Figure 2 and Figure 5 In some examples, the positioning structure 111 is provided as one of a positioning boss and a positioning groove.

[0067] The positioning structure 111 is provided as the positioning boss or the positioning groove, the second end of the spring can be sleeved on the positioning boss or inserted into the positioning groove, both structures can position and install the spring, which is convenient for the spring to exert the elastic force on the contact bridge 1, and can also stabilize and limit the spring, and the structure is simple and convenient for quick assembly.

[0068] In the embodiment, the elastic member 24 is provided as a spring, the first end of the spring can abut against the hole wall of the assembly hole 23, and the second end of the spring can abut against the contact bridge 1, so that the contact bridge 1 can be driven to act by the elastic force of the spring itself. Of course, the elastic member 24 can also be provided as a spring washer or a spring leaf and the like elastic component, which can achieve the same technical effect.

[0069] Whether provided as the positioning boss or the positioning groove, the positioning structure is directly provided on the main body 11 of the contact bridge 1 and can be made by stamping, which ensures the integrity of the structure of the contact bridge 1 and reduces the machining process and facilitates assembly.

[0070] With reference to Figure 5 In some examples, the main body 11 further includes a first limiting groove 15 and a second limiting groove 16, and the first limiting groove 15 and the second limiting groove 16 are oppositely arranged on two sides of the main body 11.

[0071] The first limiting groove 15 and the second limiting groove 16 are arranged to achieve fixed installation of the contact bridge 1, and the first limiting groove 15 and the second limiting groove 16 are oppositely arranged on two sides of the main body 11, which can cooperate with the structure on the contact support 2 located on both sides of the contact bridge 1 to achieve limiting installation of the contact bridge 1, and the assembly operation is simple, which is conducive to improving the assembly efficiency.

[0072] The first limiting groove 15 is arranged at the third end of the main body 11, and the third end is adjacent to the first end and the second end. Correspondingly, the second limiting groove 16 is arranged at the fourth end of the main body 11, and the fourth end is also adjacent to the first end and the second end and opposite to the third end.

[0073] With reference to Figure 5 and Figure 6In some examples, the assembly hole 23 includes a first limiting ridge 25 and a second limiting ridge 26, the first limiting groove 15 is connected to the first limiting ridge 25 in correspondence, and the second limiting groove 16 is connected to the second limiting ridge 26 in correspondence.

[0074] The contact bridge 1 is matched with the first limiting ridge 25 through the first limiting groove 15 and matched with the second limiting ridge 26 through the second limiting groove 16 in the assembly hole 23, so as to clamp the contact bridge 1 between the first limiting ridge 25 and the second limiting ridge 26, and the contact bridge 1 can move along the length direction of the first limiting ridge 25 and the second limiting ridge 26 to realize the relative movement of the contact bridge 1. This matching form has the characteristics of simple assembly operation and high assembly efficiency.

[0075] Specifically, the first limiting ridge 25 and the second limiting ridge 26 are arranged on the hole wall of the assembly hole 23 in correspondence, and when the contact bridge 1 is installed into the assembly hole 23, the contact bridge 1 needs to be first inclined and then inserted into the assembly hole 23. When the first limiting groove 15 is aligned with the first limiting ridge 25 and the second limiting groove 16 is aligned with the second limiting ridge 26, the contact bridge 1 is flipped to be horizontal, and the clamping is realized. In this way, the contact bridge 1 cannot be separated from the assembly hole 23 without human operation, which has high assembly stability and simple assembly operation and high assembly efficiency.

[0076] Referring to Figure 5 and Figure 6 In some examples, the first limiting groove 15 is provided with a first avoiding groove 151 and a second avoiding groove 152, the first avoiding groove 151 and the second avoiding groove 152 correspondingly avoid the edges of the first limiting ridge 25, and the second limiting groove 16 is provided with a third avoiding groove 161 and a fourth avoiding groove 162, the third avoiding groove 161 and the fourth avoiding groove 162 correspondingly avoid the edges of the second limiting ridge 26.

[0077] By correspondingly avoiding the edges of the first limiting ridge 25 through the first avoiding groove 151 and the second avoiding groove 152, the situation that the edges of the first limiting ridge 25 are stuck with the groove wall of the first limiting groove 15 can be reduced. Similarly, by correspondingly avoiding the edges of the second limiting ridge 26 through the third avoiding groove 161 and the fourth avoiding groove 162, the situation that the edges of the second limiting ridge 26 are stuck with the groove wall of the second limiting groove 16 can be reduced. In this way, the contact bridge 1 can be prevented from being stuck when it moves in the assembly hole 23, and quick assembly can be realized in the assembly process.

[0078] In the embodiment, the first limiting groove 15 is a rectangular groove, and the first limiting ridge 25 is also a rectangle. The edges of the first limiting ridge 25 are right angles, and the corners of the groove bottom and the groove wall of the first limiting groove 15 are also right angles. Therefore, the edges of the first limiting ridge 25 are easily stuck at the corners of the first limiting groove 15, causing the contact bridge 1 to be unable to move. The second limiting groove 16 and the second limiting ridge 26 are the same.

[0079] The first and second avoiding grooves 151 and 152 are arranged at the corners of the groove bottom and the groove wall of the first limiting groove 15, so as to avoid the edges of the first limiting ridge 25 and prevent the situation of being stuck.

[0080] The above merely provides preferred embodiments of the present application but is not intended to limit the present application. For those skilled in the art, the present application can have various modifications and changes. Any modified, equivalent replaced, improved, etc. within the spirit and principle of the present application shall be included in the protection scope of the present application.
