[0036] It should also be noted that, unless otherwise clearly specified and limited, the terms "disposed" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0037] In the existing plug-in circuit breaker, the circuit breaker is plugged into the base 20 through a plug-in board; the plug-in board has complex molding, unstable contact, inconvenient plug-in and pull-out, high cost, and large occupied area, which affects the promotion and use of the plug-in circuit breaker.

[0038] In view of this, to solve the above problems, please refer to Figure 1 As shown, an embodiment of the present application provides an electrical connection structure, including: a contact assembly 11 arranged on a circuit breaker body 10, and a conductive component 21 arranged on a base 20, through which the contact assembly 11 and one side of the conductive component 21 are electrically conductive to enable the circuit breaker body 10 and the base 20 to be plugged in and out of the electrical connection.

[0039] Contact components 11 are respectively provided on both sides of the circuit breaker body 10, and a conductive component 21 is provided on the base 20. One side of the circuit breaker body 10 is connected to the conductive component 21 through the contact component 11, and the other side is externally connected to the wire 30 through the contact component 11. Surface contact or line contact is formed between the contact component 11 and the conductive component 21 on one side and between the contact component 11 and the wire 30 on the other side, so that the circuit breaker body 10 and the base 20 are plugged and unplugged electrically connected.

[0040] The circuit breaker body 10 and the base 20 are pluggable and connected. For example, the circuit breaker body 10 in the present application can be connected along Figure 1 The breaker body 10 is plugged in and out of the base 20 in the up and down direction, and such plugging and unplugging operation is simple and convenient. The left and right sides of the circuit breaker body 10 are respectively provided with wiring terminals, one end of which is the incoming terminal and the other end is the outgoing terminal. The incoming terminal and the outgoing terminal are respectively connected to the contact assembly 11 on the same side, and the contact assembly 11 is used for the conduction between the circuit breaker body 10 and the external line.

[0041] A conductive component 21 is provided on one side of the base 20, and the conductive component 21 is used to abut and conduct with the contact component 11 on one side of the circuit breaker body 10. In this way, when the circuit breaker body 10 is inserted into the base 20, the contact component 11 and the conductive component 21 are in surface contact or line contact, so that the circuit breaker body 10 and the base 20 can be plugged in and out and conduct; when the circuit breaker body 10 is pulled out from the base 20, the contact component 11 and the conductive component 21 are separated, and the circuit breaker body 10 and the base 20 are disconnected.

[0042] Existing pluggable circuit breakers are usually plugged into the base by clamping, which requires contact with both sides of the conductive component of the base. In the present application, the contact assembly 11 contacts one side of the conductive component 21 to achieve pluggable conductivity between the circuit breaker body 10 and the base 20.

[0043] In the present application, the conductive component 21 is a bus bar. In other embodiments, the conductive component 21 may also be a terminal block, a wire, etc.

[0044] like Fig.12 and Fig.13 As shown, a contact assembly 11 is also provided on the other side of the circuit breaker body 10 , and the contact assembly 11 on this side is used to connect a wire 30 , and the load is connected through the wire 30 , and the wire 30 passes through the base 20 and the contact assembly 11 to form surface contact or line contact.

[0045] A surface contact or a line contact is formed between the contact assembly 11 and the conductive component 21 on one side, and a surface contact or a line contact is also formed between the contact assembly 11 and the wire 30 on the other side, thereby realizing the circuit connection between the circuit breaker body 10 and the base 20, and between the circuit breaker body 10 and the load. The surface contact or the line contact makes the contact between the circuit breaker body 10 and the base 20, and between the circuit breaker body 10 and the load more stable, and the plugging and unplugging with the base 20 is more convenient.

[0046] Therefore, the electrical connection structure provided in the embodiment of the present application can make the circuit breaker body 10 pluggable and arranged on the base 20 through the electrical connection structure, and the two sides of the circuit breaker body 10 are respectively connected with the contact components 11 through the wiring terminals, and correspondingly, the base 20 is provided with a conductive component 21, and the contact component 11 on one side and the conductive component 21 form a surface-to-surface contact, so that the circuit breaker body 10 and the base 20 are pluggable and electrically connected; and the contact component 11 on the other side is connected to the load through the wire 30, and the contact component 11 and the wire 30 also form a surface-to-surface contact; in this way, the circuit breaker The body 10 realizes surface contact or line contact with the conductive component 21 on the base 20 through the contact component 11 on one side, thereby realizing the circuit connection between the circuit breaker body 10 and the base 20; and realizes surface contact or line contact with the wire 30 on the other side, thereby realizing the circuit connection between the circuit breaker body 10 and the load; the circuit connection mode of surface contact or line contact can make the contact between the circuit breaker body 10 and the base 20, and between the circuit breaker body 10 and the load more stable, and at the same time, the circuit breaker body 10 can be more conveniently plugged in and out of the base 20, which is convenient to operate and highly practical. In addition, the structure of the conductive component 21 formed on the base 20 is relatively simple, which can simplify the overall structure of the electrical connection structure, reduce costs and occupied area, and is conducive to the promotion of product applicability.

[0047] Specifically, in one possible implementation of the present application, Figure 2 As shown, a conductive portion 21 a is provided on the conductive component 21 , and the contact component 11 abuts against the conductive portion 21 a , so that the contact component 11 and the conductive component 21 are in surface contact or line contact.

[0048] The conductive component 21 includes a row body and a conductive portion 21a. The contact assembly 11 and the conductive portion 21a form surface contact or line contact. The circuit breaker body 10 and the base 20 are connected in circuit by abutting the contact assembly 11 and the conductive portion 21a.

[0049] The conductive portion 21a forms a conductive surface in the direction toward the contact component 11. Similarly, the contact component 11 also forms a conductive surface in the direction toward the conductive portion 21a. When the two conductive surfaces abut against each other, surface contact or line contact is formed.

[0050] like Fig.14 , Fig.15As shown, there are multiple conductive parts 21a, which are arranged side by side to correspond to the multiple contact components 11 respectively; similarly, the multiple contact components 11 on the other side are arranged to correspond to the wires 30 one by one.

[0051] Furthermore, if Figure 3 As shown, the contact assembly 11 includes: a contact plate 110 and an elastic member 111 disposed on one side of the contact plate 110 , and the other side of the contact plate 110 forms a contact portion 110 a .

[0052] For example, Figure 4 and Figure 5 As shown, a protruding contact portion 110 a is formed on the contact plate 110 of the present application. The contact portion 110 a extends out of the housing 101 of the circuit breaker 10 to form surface contact or line contact or line contact area with the conductive portion 21 a on the base 20 .

[0053] The wiring assembly 11 is located in the housing 101 of the circuit breaker 10 to be connected to the wiring terminal of the circuit breaker 10. A conductive component is provided on the base 20, and a conductive portion 21a is provided on the conductive component. The contact portion 110a of the contact plate 110 is used to connect with the conductive portion 21a of the base 20. The contact portion 110a is provided to protrude, so that an electrical gap can be formed between the base 20 and the circuit breaker 10. The contact portion 110a may extend out of the housing 101 of the circuit breaker 10, or may not extend out of the housing 101.

[0054] Or, if Figure 6 , Figure 7 As shown, the contact plate 110 is a flat plate structure, a protrusion is formed on the conductive component, and the protrusion of the conductive component and the contact portion 110a are conductive. The conductive portion 21a is protruding, and the protrusion of the conductive component (conductive portion 21a) penetrates the housing 101 of the circuit breaker 10 and is in conductive contact with the contact plate 110.

[0055] When the conductive portion 21a of the conductive component extends into the housing 101 of the circuit breaker 10, the interior of the circuit breaker 10 can be extremely simple, saving a lot of space inside the circuit breaker 10, and the circuit breaker 10 is smaller and more compact.

[0056] Further, a first bump is formed on the contact portion 110a, and the contact portion 110a is connected to the conductive component through the first bump; and / or, as Figure 8 , Fig. 9 As shown, a second bump 21a1 is formed on the protruding portion, and the second bump 21a1 is connected to the contact portion 110a.

[0057] The arrangement of the bumps makes the connection more stable. The bumps can be arranged on the contact portion 110a or on the protruding portion (eg Figure 7 In addition, the second protrusion 21a1 may be provided on the contact portion 110a and the protruding portion.

[0058] The contact portion 110a and the conductive portion 21a abut to form surface contact or line contact or a line contact area. The larger the surface contact or line contact or line contact area, the more stable the abutment between the contact portion 110a and the conductive portion 21a, and the more stable the contact between the circuit breaker 10 and the base 20.

[0059] Please refer to Figure 4 As shown, when the contact portion 110a protrudes from the contact plate 110, extended contact ends 110b are formed on the contact plate 110 at both sides of the contact portion 110a. The extended contact ends 110b and the contact portion 110a are located in different planes, and the two ends of the elastic member 111 are respectively fixed on the two extended contact ends 110b.

[0060] The extended contact end 110b on one side, the contact portion 110a, and the extended contact end 110b on the other side are sequentially connected to form a contact plate 110, and the contact portion 110a protrudes from the extended contact end 110b, so that the contact plate 110 forms a "X"-shaped structure; the extended contact end 110b on one side extends upward, and the extended contact end 110b on the other side extends downward and is bent into an L shape; the two ends of the elastic member 111 in the up and down directions are fixed on the corresponding extended contact ends 110b, so that the contact plate 110 and the elastic member 111 are connected.

[0061] When the contact plate 110 and the elastic member 111 are connected, a waist-shaped hole 111a is provided on the elastic member 111, and both ends of the elastic member 111 are fixed to the extended contact end 110b by screws passing through the waist-shaped hole 111a. The setting of the waist-shaped hole 111a can change the relative position between the elastic member 111 and the contact plate 110, and can ensure the displacement stroke of the relative movement of the circuit breaker 10 and the base 20.

[0062] In addition, the wiring assembly 11 further includes a supporting member matched with the elastic member 111 , and the supporting member is located on a side of the elastic member 111 away from the contact portion 110 a .

[0063] The side of the elastic member 111 away from the contact plate 110 is connected to a fixing seat 113, which is fixed to the housing 101 of the circuit breaker 10, or the fixing seat 113 and the housing 101 are integrally provided, and the fixing seat 113 is used to provide a fixed support for the elastic member 111. The fixing seat 113 can be used to fix the elastic member 111 and provide a recoil reaction force guarantee for the deformation of the elastic member 111.

[0064] In one embodiment, the support member is a support shaft 112 fixed between the elastic member 111 and the fixing seat 113, so as to balance the forces on the parts of the elastic member 111 located on both sides of the support shaft 112. The support shaft 112 is only used to support the elastic member 111.

[0065] The support shaft 112 is a support shaft, and the support shaft is located at the support position of the fixing seat 113 on the elastic member 111 to ensure the force balance on both sides of the support shaft 112. For example, in the up and down direction, the support shaft 112 is located on the center line of the elastic member 111.

[0066] Furthermore, a first groove 111 b is formed on the elastic member 111 , and a second groove 113 a is formed on the fixing seat 113 . The first groove 111 b and the second groove 113 a are arranged opposite to each other to form an accommodating space for accommodating the supporting shaft 112 .

[0067] The notch of the first groove 111b of the elastic member 111 faces the fixing seat 113, and the notch of the second groove 113a of the fixing seat 113 faces the elastic member 111. The first groove 111b and the second groove 113a are opposite to each other to form an accommodating space, and the support shaft 112 is fixed in the accommodating space.

[0068] In addition, the first groove 111 b protrudes toward the contact plate 110 , so that the elastic member 111 forms a quasi-X-shaped structure. The protrusion direction of the first groove 111 b is the same as that of the contact portion 110 a , and the first groove 111 b corresponds to the contact portion 110 a of the contact plate 110 .

[0069] In another embodiment, the support member is a boss 1130 on the fixing seat 113 facing the elastic member 111 . In this case, the fixing seat 113 has both a supporting function and a fixing function.

[0070] For the conductive component 21, Fig.11 As shown, in one embodiment of the present application, the conductive portion 21 a is located on the row body of the conductive component 21 , and the conductive portion 21 a is arranged to protrude from the row body so that the conductive component 21 forms a wavy structure.

[0071] The conductive component 21 forms a protrusion at the conductive portion 21a, so that the conductive portion 21a protrudes from the row body, so that the conductive component 21 as a whole forms a wavy structure; and the contact assembly 11 also protrudes from the side of the circuit breaker body 10. Through the protruding conductive portion 21a and the contact assembly 11, a certain gap can be formed between the side of the circuit breaker body 10 and the base 20, which can increase the electrical gap and limit.

[0072] In another embodiment of the present application, the conductive portion 21 a is located on the array of the conductive component 21 , and the conductive portion 21 a and the array are located on the same plane, so that the conductive component 21 forms a flat plate structure.

[0073] The conductive component 21 is a flat plate structure as a whole, and the conductive part 21a and the row body are in the same plane. The flat plate structure is convenient for the processing and manufacturing of the conductive component 21, which can effectively reduce the cost, and can also achieve surface contact or line contact between the conductive part 21a and the contact component 11. In addition, the contact component 11 protrudes from the side of the circuit breaker body 10, and can also form a certain gap between the side of the circuit breaker body 10 and the base 20, which is conducive to electrical gap and limit. When the conductive component 21 is a flat plate structure, the contact part 110a of the circuit breaker body 10 is provided with a protrusion to contact the flat plate, and a convex point can also be added to the flat plate structure to contact the contact part 110a of the circuit breaker body 10.

[0074] For the connection of the wire 30 , a fixing hole is formed on the base 20 , one end of the wire 30 is connected to the contact assembly 11 through the fixing hole, and the other end extends out of the base 20 .

[0075] A wire 30 is passed through the fixing hole. Fig.16 As shown, one end of the wire 30 is connected to the contact assembly 11 on one side, and the other end is connected to the load externally, so as to realize the circuit connection of the load, the wire 30, and the contact assembly 11; after the circuit breaker body 10 is plugged into and unplugged from the base 20, the wire 30 is fixed and limited by the fixing hole on the base 20, so as to realize the electrical connection between the circuit breaker body 10 and the wire 30, and to connect the corresponding load externally.

[0076] The electrical connection is generally divided into live wire and neutral wire. In this application, Fig.10 and Fig.11 As shown, the conductor 30 includes a neutral wire and a live wire, the conductive component 21 includes a neutral wire conductive component 21N and a live wire conductive component 21L, and the contact assembly 11 includes a neutral wire contact assembly 11N connected to the neutral wire conductive component 21N and the neutral wire respectively, and a live wire contact assembly 11L connected to the live wire conductive component 21L and the live wire respectively.

[0077] On the same circuit breaker body 10, the neutral line, the neutral line contact assembly 11N, and the neutral line conductive component 21N are connected correspondingly, and the live line, the live line contact assembly 11L, and the live line conductive component 21L are connected correspondingly; that is, the neutral line contact assembly 11N and the live line contact assembly 11L form a group of contact assemblies 11, and there is a group of contact assemblies 11 on both sides of a circuit breaker body 10.

[0078] Similarly, the conductive component 21 includes a neutral conductive component 21N and a live conductive component 21L. For the contact component 11 on one side, the neutral conductive component 21N corresponds to the neutral contact component 11N, and the live conductive component 21L corresponds to the live contact component 11L. A plurality of conductive portions 21a are provided on the neutral conductive component 21N and the live conductive component 21L. A conductive portion 21a on the neutral conductive component 21N and a conductive portion 21a on the live conductive component 21L form a group. The two conductive portions 21a of a group are respectively connected by surface contact or line contact with the corresponding neutral contact component 11N and live contact component 11L on the same side of the same circuit breaker body 10.

[0079] For the contact assembly 11 on the other side of the circuit breaker body 10 , the neutral line is directly connected to the neutral line contact assembly 11N on this side, and the live line is directly connected to the live line contact assembly 11L on this side.

[0080] When the circuit breaker is a multi-pole circuit breaker, the multi-pole circuit breaker has a main circuit breaker body 10a and multiple branch circuit breaker bodies 10b arranged in parallel. The conductive component 21 of the base 20 is correspondingly provided with multiple conductive parts 21a to be electrically connected to the main circuit breaker body 10a and the branch circuit breaker body 10b respectively.

[0081] In a multi-pole circuit breaker, two sides of each circuit breaker body 10 are respectively connected to a group of conductors 30 (including a neutral line and a live line) and a group of conductive parts 21a on the conductive component 21 (the conductive part 21a of the neutral line conductive component 21N and the conductive part 21a of the live line conductive component 21L).

[0082] The contact assembly 11 at the incoming end of the main circuit breaker body 10a is connected to the main conductor, the contact assembly 11 at the outgoing end of the main circuit breaker body 10a is connected to the conductive component 21, and multiple branch circuit breaker bodies 10b are connected in parallel through the conductive component 21.

[0083] For example, the incoming wire end on one side of the main circuit breaker body 10a adopts a round hard single-core wire 30, and passes through the contact assembly 11 at the incoming wire end through the inside of the main circuit breaker body 10a to reach the contact assembly 11 at the outgoing wire end on the other side, and then connects to the conductive component 21 through the conductive part 21a; and then reaches each branch circuit breaker body 10b through the conductive component 21. Each branch circuit breaker body 10b enters the wire through the conductive component 21 and exits the wire through the left side of the branch circuit breaker body 10b, forming a circuit connection of a multi-pole circuit breaker.

[0084] Alternatively, the multi-strand wires 30 may be provided with wiring terminals or copper sleeves to achieve corresponding wiring results.
