[0060] A surge protector, also known as a lightning arrester, is an electronic device that provides safety protection for various instruments and communication lines. When a spike current or voltage suddenly occurs in an electrical circuit or communication line due to external interference, the surge protector can conduct and divert the current in an extremely short time, thereby avoiding damage to other devices in the circuit caused by surges. The overvoltage limiting component in the surge protector plays a role in conducting and diverting the current, and the overvoltage limiting component needs to be connected to the circuit board.

[0061] Currently, the overvoltage limiting component is electrically connected to the conductive connecting component by welding. However, the welding method makes the preparation and assembly process of the surge protector complicated and inefficient; the lengths of the first connection ends of the overvoltage limiting components are different, and it is impossible to ensure the welding consistency; as a result, the cost is relatively high.

[0062] The connecting component proposed in this application can be electrically connected to the overvoltage limiting component, so that the overvoltage limiting component can be electrically connected to the circuit board to be protected through the connecting component. The accommodating groove of the connecting body of the connecting component can be used to accommodate the first connection end of the overvoltage limiting component. The opposite sides of the first connection end of the overvoltage limiting component abut against the inner walls of the accommodating groove opposite to each other, so that the first connection end contacts the inner wall of the accommodating groove and has a frictional force. The frictional force generated by the abutment between the first connection end and the inner wall of the accommodating groove fixes the connecting body in the accommodating groove and makes the connecting body electrically connected to the first electrical connection end, so that the overvoltage limiting component can be reliably electrically connected to the circuit board to be protected.

[0063] When assembling the connecting component and the overvoltage limiting component, the first connection end of the overvoltage limiting component can extend into the accommodating groove through the opening of the accommodating groove, so that the overvoltage limiting component and the connecting component can be fixed and electrically connected. This not only makes the connecting component and the overvoltage limiting component have a reliable connection effect, but also makes the assembly process of the connecting component and the overvoltage limiting component more convenient, thereby improving the assembly efficiency of the connecting component and the overvoltage limiting component.

[0064] In the surge protector proposed by the present application, the connecting member is the above-mentioned connecting member. Therefore, a reliable electrical connection effect can be achieved between the connecting member and the overvoltage limiting member, and the assembly of the connecting member and the overvoltage limiting member is more convenient, thereby making the production efficiency of the surge protector higher.

[0065] In the overvoltage limiting member proposed by the present application, the component is electrically connected to the connecting member. The accommodating groove of the connecting member can be used to accommodate the third connection end of the circuit board to be protected. The opposite sides of the third connection end of the circuit board to be protected abut against the opposite inner walls of the accommodating groove, so that the third connection end contacts the inner wall of the accommodating groove and has friction. The friction generated by the abutment between the third connection end and the inner wall of the accommodating groove fixes the third connection end in the accommodating groove and makes the third connection end electrically connected to the overvoltage limiting member, so that the overvoltage limiting member can be reliably electrically connected to the circuit board to be protected.

[0066] When assembling the overvoltage limiting member and the circuit board to be protected, the third connection end of the circuit board to be protected can extend into the accommodating groove through the groove opening of the accommodating groove, so that the overvoltage limiting member and the third connection end can be fixed and electrically connected. This not only makes the third connection end and the overvoltage limiting member have a reliable connection effect, but also makes the assembly process of the third connection end and the overvoltage limiting member more convenient, thereby improving the assembly efficiency of the circuit board to be protected and the overvoltage limiting member.

[0067] The following will specifically describe the connecting member, overvoltage limiting member, and surge protector provided by the present application with reference to specific embodiments.

[0068] An embodiment of the present application proposes a connecting member, which can be used to connect an overvoltage limiting member and a circuit board to be protected. This connecting member can be applied to a surge protector.

[0069] Refer to Figures 1 to 3 As shown, the connecting member includes a connecting body 100. Among them, the connecting body 100 is the basic component of the connecting member of the present application, and the connecting body 100 can provide an installation basis for at least other parts of the connecting member. The connecting member is provided with an accommodating groove 110. Correspondingly, a groove opening communicating with the accommodating groove 110 is provided on the surface of the connecting member. The overvoltage limiting member 200 has a first connection end 220, and the first connection end 220 of the overvoltage limiting member 200 is the part on the overvoltage limiting member 200 for electrically connecting to an external electrical connection structure. The first connection end 220 of the overvoltage limiting member 200 is embedded in the accommodating groove 110 of the connecting body 100, and the opposite sides of the first connection end 220 respectively abut against the two opposite inner walls in the accommodating groove 110. Thus, the first connection end 220 can be fixed in the accommodating groove 110, and the overvoltage limiting member 200 can be electrically connected to the connecting body 100.

[0070] Specifically, the first connection ends 220 connecting the connection main body 100 and the overvoltage limiting component 200 are both electrical connection structural members, and when the connection main body 100 contacts the first connection ends 220 of the overvoltage limiting component 200, they can conduct electricity. When the first connection ends 220 of the overvoltage limiting component 200 are embedded in the accommodation grooves 110 of the connection main body 100, the outer walls on the opposite sides of the first connection ends 220 of the overvoltage limiting component 200 respectively abut against the opposite inner walls in the accommodation grooves 110, so that the outer walls on the opposite sides of the first connection ends 220 of the overvoltage limiting component 200 can contact the opposite inner walls in the accommodation grooves 110, thereby enabling there to be a frictional force between the first connection ends 220 of the overvoltage limiting component 200 and the connection main body 100. The frictional force between the connection main body 100 and the first connection ends 220 of the overvoltage limiting component 200 can, to a certain extent, serve the purpose of limiting the first connection ends 220, preventing the overvoltage limiting component 200 and / or the connection main body 100 from being easily displaced relative to each other under the action of an external force, so that the first connection ends 220 of the overvoltage limiting component 200 and the connection main body 100 can maintain a state of contact connection, and in this way, the overvoltage limiting component 200 and the connection main body 100 have a reliable electrical connection effect.

[0071] When it is necessary to install the first connection ends 220 of the overvoltage limiting component 200 into the accommodation grooves 110 of the connection main body 100, the first connection ends 220 of the overvoltage limiting component 200 can be inserted into the accommodation grooves 110 through the groove openings of the accommodation grooves 110, so that the first connection ends 220 are fixed in the accommodation grooves 110. When disassembling the connection member and the overvoltage limiting component 200, an acting force can be applied to the first connection ends 220 of the overvoltage limiting component 200, and after this acting force overcomes the frictional force between the first connection ends 220 and the inner walls of the accommodation grooves 110, the first connection ends 220 can be moved out from the groove openings of the accommodation grooves 110.

[0072] In some embodiments, referring to Figures 2 to 3 as shown, the connection main body 100 of the present application can specifically be provided with a first connection portion 120 and a second connection portion 130. Among them, the first connection portion 120 is connected to the second connection portion 130, and the first connection portion 120 and the second connection portion 130 are bent, so that the first connection portion 120 and the second connection portion 130 can be oppositely arranged. The accommodation grooves 110 of the connection main body 100 are located between the first connection portion 120 and the second connection portion 130, so that the opposite wall surfaces of the first connection portion 120 and the second connection portion 130 can form the opposite inner walls of the accommodation grooves 110.

[0073] Specifically, one end of the first connecting portion 120 is connected to one end of the second connecting portion 130, and the other end of the first connecting portion 120 and the other end of the second connecting portion 130 are separated. The other end of the first connecting portion 120 and the other end of the second connecting portion 130 can form the slot opening of the accommodating slot 110, and the connecting portion of the first connecting portion 120 and the second connecting portion 130 can form the bottom wall of the accommodating slot 110. The first connecting portion 120 and the second connecting portion 130 can be an integral structural member, and the second connecting portion 130 is bent relative to the first connecting portion 120 through a sheet metal process, so as to form the accommodating slot 110 between the first connecting portion 120 and the second connecting portion 130. In this way, the process of forming the accommodating slot 110 on the connecting body 100 can be made simpler and more convenient, thereby improving the preparation efficiency of the connecting member.

[0074] In some embodiments, as shown in Figures 2 to 4 the first connecting portion 120 has a first abutting surface 121a, the second connecting portion 130 has a second abutting surface 131, the first abutting surface 121a and the second abutting surface 131 are arranged oppositely, and the first abutting surface 121a and the second abutting surface 131 form the opposite inner walls of the accommodating slot 110. When the first connection end 220 of the overvoltage limiting member 200 is located in the accommodating slot 110, the opposite sides of the first connection end 220 can respectively abut against the first abutting surface 121a and the second abutting surface 131, so that the opposite sides of the first connection end 220 and the first abutting surface 121a and the second abutting surface 131 have frictional force.

[0075] The first connecting portion 120 and the second connecting portion 130 can be connected in an elastic connection manner, so that the first connecting portion 120 and the second connecting portion 130 can move relative to each other. In this way, the distance between the first abutting surface 121a and the second abutting surface 131 can be adjusted, so that the degree of fitting between the opposite sides of the first connection end 220 of the overvoltage limiting member 200 and the first abutting surface 121a and the second abutting surface 131 can be adjusted, and further the frictional force between the opposite sides of the first connection end 220 of the overvoltage limiting member 200 and the first abutting surface 121a and the second abutting surface 131 can be adjusted.

[0076] Specifically, when the first connection end 220 of the overvoltage limiting member 200 is not disposed in the receiving groove 110 of the connection body 100 and the first connection portion 120 and the second connection portion 130 are in a natural state, the distance between the first abutting surface 121a and the second abutting surface 131 can be set to be less than the thickness dimension of the first connection end 220. When the first connection end 220 is inserted into the receiving groove 110 through the groove opening of the receiving groove 110, the first connection end 220 can squeeze the first connection portion 120 and the second connection portion 130, so that the first connection portion 120 and the second connection portion 130 move in opposite directions. In this way, the distance between the first abutting surface 121a and the second abutting surface 131 can be increased to match the thickness dimension of the first connection end 220, and the elastic acting force between the first connection portion 120 and the second connection portion 130 enables the first abutting surface 121a and the second abutting surface 131 to be pressed against opposite sides of the first connection end 220, so that the first abutting surface 121a and the second abutting surface 131 can be closely attached to opposite sides of the first connection end 220.

[0077] In some embodiments, the second connection portion 130 can also adopt an elastic structural member. Specifically, the second connection portion 130 can be prepared by using an elastic material member, so that the second connection portion 130 itself has elasticity. In this way, the second connection portion 130 can also move relative to the first connection portion 120 and can be reset under the elastic acting force. The first connection portion 120 can also adopt an elastic structural member, so that the first connection portion 120 itself has elasticity. In this way, the first connection portion 120 can also move relative to the second connection portion 130 and can be reset under the elastic acting force. The first connection portion 120 and the second connection portion 130 can be specifically prepared by using a copper alloy material, so that both the second connection portion 130 and the first connection portion 120 have elasticity and have good electrical conductivity.

[0078] In some embodiments, referring to Figure 4 As shown, the first connection portion 120 of the present application can be provided with a first abutting portion, and the first abutting portion is a convex structure on the first connection portion 120 facing the second abutting surface 131 of the second connection portion 130. Specifically, the first abutting portion is located on the first abutting surface 121a of the first connection portion 120. When the first connection end 220 of the overvoltage limiting member 200 is disposed in the receiving groove 110 of the connection body 100, the first abutting portion can abut against the side wall of the first connection end 220, so that the abutting contact effect between the first connection portion 120 and the first connection end 220 is more reliable, and further the electrical connection effect between the first connection portion 120 and the first connection end 220 is more reliable, and finally the electrical connection effect between the connection member and the overvoltage limiting member 200 is reliable.

[0079] Specifically, the area of the contact portion between the first abutting portion on the first connecting portion 120 and the first connecting end 220 of the overvoltage limiting member 200 is smaller than the area of the first abutting surface 121a. In this way, when the first abutting portion contacts the first connecting end 220, the pressure exerted by the first abutting portion on the first connecting end 220 is greater, so that the abutting contact effect between the first abutting portion and the first connecting end 220 is more reliable.

[0080] In addition, the second connecting portion 130 of the present application may further be provided with a second abutting portion 132. The second abutting portion 132 is a convex structure on the second abutting surface 131 of the second connecting portion 130 facing the first connecting portion 120. Specifically, the second abutting portion 132 is located on the second abutting surface 131 of the second connecting portion 130. When the first connecting end 220 of the overvoltage limiting member 200 is disposed in the receiving groove 110 of the connecting body 100, the second abutting portion 132 can abut and contact the side wall of the first connecting end 220, so that the abutting contact effect between the second connecting portion 130 and the second connecting end 124 is more reliable, and further the electrical connection effect between the second connecting portion 130 and the first connecting end 220 is more reliable, and finally the electrical connection effect between the connecting member and the overvoltage limiting member 200 is reliable.

[0081] Specifically, the area of the contact portion between the second abutting portion 132 on the second connecting portion 130 and the first connecting end 220 of the overvoltage limiting member 200 is smaller than the area of the second abutting surface 131. In this way, when the second abutting portion 132 contacts the first connecting end 220, the pressure exerted by the second abutting portion 132 on the first connecting end 220 is greater, so that the abutting contact effect between the second abutting portion 132 and the first connecting end 220 is more reliable.

[0082] The first abutting portion and the second abutting portion 132 can be oppositely arranged. In this way, when the first connecting end 220 is disposed in the receiving groove 110, the opposite sides of the first connecting end 220 can respectively abut and contact the first abutting portion and the second abutting portion 132, so that the forces on the opposite sides of the first connecting end 220 are balanced, and further the first connecting end 220 is more stable and reliable when disposed in the receiving groove 110.

[0083] In some embodiments, refer to Figure 4 and Figure 5As shown, the first connecting portion 120 of the present application is specifically provided with a first connecting section 121 and a second connecting section 122 connected to each other. Among them, the first connecting section 121 is disposed opposite to the second connecting portion 130, and a receiving groove 110 is formed between the first connecting section 121 and the second connecting portion 130. When the first connecting end 220 of the overvoltage limiting member 200 is located in the receiving groove 110, the opposite sides of the first connecting end 220 can respectively abut against the first connecting section 121 and the second connecting portion 130. The second connecting section 122 is the part of the first connecting portion 120 for electrically connecting with the circuit board to be protected, and at least part of the second connecting section 122 is arranged in a dislocation manner with respect to the second connecting portion 130, that is, the second connecting section 122 is an extended structure on the first connecting section 121, so that the second connecting section 122 can be conveniently electrically connected to the structure of the circuit board to be protected.

[0084] Specifically, the first end of the first connecting section 121 is elastically connected to one end of the second connecting portion 130, and the second connecting portion 130 can move relative to the first connecting section 121, so that the distance between the first connecting section 121 and the second connecting portion 130 can be adjusted, thereby adjusting the size of the receiving groove 110. The length dimension and the external shape structure of the second connecting section 122 can be determined according to the actual installation position of the circuit board to be protected, and the present application does not limit the specific structure of the second connecting section 122.

[0085] In some embodiments, referring to Figure 4 As shown, on one side of the first connecting section 121 facing away from the connection between the first connecting section 121 and the second connecting portion 130, there is a first opening end 121b, and on one side of the second connecting portion 130 facing away from the connection between the first connecting section 121 and the second connecting portion 130, there is a second opening end 133. The first opening end 121b and the second opening end 133 extend in opposite directions, and the first opening end 121b and the second opening end 133 are the slot openings of the receiving groove 110, so that the slot opening of the receiving groove 110 has an outwardly expanding structure. In this way, when the first connecting end 220 of the overvoltage limiting member 200 is inserted into the receiving groove 110 through the slot opening of the receiving groove 110, the first opening end 121b and the second opening end 133 can play a role in guiding the insertion of the first connecting end 220, so that the first connecting end 220 can be more conveniently inserted into the receiving groove 110.

[0086] Specifically, the first opening end 121b is bent relative to the main body portion of the first connecting section 121, and the second opening end 133 is bent relative to the main body portion of the second connecting portion 130. The main body portions of the first connecting section 121 and the second connecting portion 130 can extend in the vertical direction, so that the structure of the connecting main body 100 is relatively more compact.

[0087] In some embodiments, referring to Figure 4As shown, a first notch 123 may be provided between the first open end 121b of the first connection segment 121 of the present application and the second connection segment 122. The first notch 123 causes the first open end 121b and the second connection segment 122 to be in a separated and unconnected state. In this way, the first open end 121b can be bent relative to the first connection segment 121 alone, so that the second connection segment 122 is not affected.

[0088] Specifically, when preparing the first connection portion 120, the first notch 123 can be formed in a plate-like structural member, and one end of the first connection segment 121 is bent relative to the first connection segment 121 to form the first open end 121b, which makes the preparation of the first connection portion 120 more convenient.

[0089] In some embodiments, with reference to Figure 6 As shown, a second notch 134 may also be provided on the second connection portion 130 of the present application. One end of the second notch 134 can extend to a side of the second connection portion 130 facing away from the connection between the second connection portion 130 and the first connection portion 120, and the other end of the second notch 134 can extend to be adjacent to the connection between the second connection portion 130 and the first connection portion 120. In this way, the second notch 134 can at least divide the second open end 133 of the second connection portion 130 into two parts, specifically into a first part and a second part, and both the first part and the second part can elastically move relative to the first connection portion 120. When the first connection end 220 of the overvoltage limiting member 200 is disposed in the receiving groove 110, the first part and the second part of the second connection portion 130 can respectively contact the first connection end 220, so that the second connection portion 130 can more reliably abut against and be electrically connected to the first connection end 220.

[0090] In some embodiments, it should be understood that, with reference to Figure 4 、 Figure 6 and Figure 7 As shown, one end of the first connection portion 120 is connected to one end of the second connection portion 130 to form a receiving groove 110 between the first connection portion 120 and the second connection portion 130, so that in addition to the groove opening opposite to the bottom wall of the receiving groove 110, the receiving groove 110 also has openings on both sides along a preset direction. The preset direction is the extending direction of the second connection portion 120, that is Figure 6in the B direction. The connecting body 100 of the present application may also be provided with a first limiting portion 140 and a second limiting portion 150. Among them, the first limiting portion 140 and the second limiting portion 150 are arranged at the openings on both sides of the accommodating groove 110, and the first limiting portion 140 and the second limiting portion 150 can play the role of limiting the first connection end 220 of the overvoltage limiting member 200 arranged in the accommodating groove 110, preventing the first connection end 220 of the overvoltage limiting member 200 from sliding out of the openings on both sides of the accommodating groove 110, so that the contact effect between both sides of the first connection end 220 and the first connection portion 120 and the second connection portion 130 is more stable and reliable.

[0091] Specifically, the first limiting portion 140 may be arranged on the first connection portion 120, and the second limiting portion 150 may be arranged on the second connection portion 130. Alternatively, both the first limiting portion 140 and the second limiting portion 150 are arranged on the first connection portion 120 and are located on both sides of the first connection portion 120. Alternatively, both the first limiting portion 140 and the second limiting portion 150 are arranged on the second connection portion 130 and are located on both sides of the second connection portion 130. The present application does not limit the specific arrangement positions of the first limiting portion 140 and the second limiting portion 150.

[0092] The present application also proposes a surge protector, referring to Figure 1 and Figure 8 as shown, the surge protector includes a base 400, an overvoltage limiting member 200 and the above-mentioned connecting member. Among them, the base 400 is a basic component of the surge protector of the present application, and the base 400 can provide an installation basis for at least other parts of the surge protector. Specifically, both the connecting member and the overvoltage limiting member 200 are arranged on the base 400, so that the overvoltage limiting member 200 and the connecting member can be fixed. Specifically, the overvoltage limiting member 200 may adopt a varistor or a gas discharge tube.

[0093] A first installation groove 410 is formed on the base 400, and the first connection portion 120 and the second connection portion 130 of the connecting member are located in the first installation groove 410, so that the accommodating groove 110 is also located in the first installation groove 410. The first installation groove 410 can play the role of limiting the first connection portion 120 and the second connection portion 130, so that the first connection portion 120 and the second connection portion 130 can be stably and reliably fixed on the base 400. The base 400 is an insulating structural member, which can avoid faults such as short circuits when the connecting member and the overvoltage limiting member 200 are arranged on the base 400.

[0094] Specifically, the outer walls of the first connecting portion 120 and the second connecting portion 130 facing away from each other can respectively abut against the inner walls of the first mounting groove 410 opposite thereto. After the first connecting portion 120 and the second connecting portion 130 exert forces on the inner walls of the first mounting groove 410, the inner walls of the first mounting groove 410 generate reaction forces on the first connecting portion 120 and the second connecting portion 130, so that the first connecting portion 120 and the second connecting portion 130 are subjected to opposite forces, and the first connecting portion 120 and the second connecting portion 130 can abut against the outer walls on the opposite sides of the first connecting end 220 of the overvoltage limiting member 200 more closely.

[0095] The other two inner walls of the first mounting groove 410 can also be opposite to the openings on both sides of the first mounting groove 410. In this way, the inner walls of the first mounting groove 410 can also limit the first connecting portion 120 and the second connecting portion 130 in other directions to prevent the first connecting portion 120 and the second connecting portion 130 from shaking in the front, back, left, and right directions, and further achieve the purpose of limiting the first connecting end 220 of the overvoltage limiting member 200.

[0096] In some embodiments, referring to Figure 1 and Figure 8 as shown, a second mounting groove 420 can also be formed on the base 400. The second connecting section 122 of the first connecting portion 120 can be disposed in the second mounting groove 420. Correspondingly, the first connecting section 121 of the first connecting portion 120 is disposed in the first mounting groove 410.

[0097] Referring to Figure 4 and Figure 5 as shown, one side of the second connecting section 122 away from the first connecting section 121 has a first distance from the preset plane, and one side of the second connecting section 122 close to the first connecting section 121 has a second distance from the preset plane, and the first distance is less than the second distance. Among them, the preset plane is as shown by A in Figure 5 , the preset plane is located on the bottom side of the second connecting section 122, and the preset plane is perpendicular to the direction from the groove opening of the receiving groove 110 to the bottom wall of the receiving groove 110. In this way, one side of the second connecting section 122 away from the first connecting section 121 is relatively closer to the preset plane. The side of the second connecting section 122 facing away from the first connecting section 121 is the second connecting end 124, and the second connecting end 124 is used for electrically connecting with the circuit board to be protected.

[0098] When the connecting member is disposed in the first mounting groove 410 and the second mounting groove 420 of the base 400, the depth of the second mounting groove 420 is set to be greater than the depth of the first mounting groove 410, so that the second connecting section 122 is closer to the bottom of the base 400. The base 400 can be disposed on the circuit board to be protected, so that the second connecting end 124 of the second connecting section 122 can be closer to the circuit board to be protected, and thus the second connecting section 122 can be more conveniently electrically connected to the circuit board to be protected.

[0099] The first mounting groove 410 and the second mounting groove 420 on the base 400 are independent grooving structures, so that the first mounting groove 410 and the second mounting groove 420 can respectively limit and fix the first connecting section 121 and the second connecting section 122, thereby making the reliability of the connecting member fixed on the base 400 better.

[0100] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
