Description

Technical Field

[0001] This application relates to the field of power distribution technology, and more particularly to an electrical device and power distribution equipment. Background Technology

[0002] The electrical device includes multiple functional modules, which are connected sequentially by wires. In related technologies, each functional module is equipped with a connection part. The two ends of a wire are generally connected to the connection parts of two adjacent functional modules in two separate steps, which results in a long connection time for multiple functional modules and low electrical connection efficiency. Utility Model Content

[0003] In view of this, this application provides an electrical device and power distribution equipment that can improve the efficiency of electrical connections between multiple functional modules.

[0004] On one hand, embodiments of this application provide an electrical device comprising at least two functional modules and at least one connector. The at least two functional modules are arranged sequentially, and each functional module has one or two first connection terminals. The connector includes a connecting section and two second connection terminals, which are respectively connected to both ends of the connecting section. The connecting section is configured to have a generally rigid structure and is electrically connected to the two second connection terminals. A first connection terminal of one functional module and a first connection terminal of an adjacent functional module are configured to be inserted into two second connection terminals of the same connector, respectively. The two first connection terminals connected to the same connector are arranged close to each other so that the insertion operation of the two second connection terminals and the corresponding two first connection terminals of a connector can be completed simultaneously by pressing the connector once.

[0005] By configuring connectors to electrically connect adjacent functional modules, the connector includes a generally rigid connecting section and two second connecting terminals. Each functional module includes two first connecting terminals. The generally rigid connecting section connects the two second connecting terminals so that the two second connecting terminals form a whole. This allows the first connecting terminals of two adjacent functional modules to be synchronously aligned with the two second connecting terminals of a connector. Furthermore, the first connecting terminals of two adjacent functional modules are positioned close together to shorten the overall length of the connector. This allows the two second connecting terminals of a connector to be simultaneously connected to the two adjacent first connecting terminals of two adjacent functional modules by pressing one connector at a time. This reduces the number of operation steps between adjacent functional modules, thereby saving wiring time for multiple functional modules and improving the electrical connection efficiency of multiple functional modules.

[0006] In at least one embodiment, the two first connection terminals plugged into the same connector are respectively located close to the edge of their respective functional modules, and the distribution direction of the two first connection terminals connected to the same connector is parallel to the distribution direction of the two adjacent functional modules.

[0007] Because of the above configuration, the distance between the two adjacent first connection terminals of two adjacent functional modules is small, which makes the overall length of the connector shorter. When the two second connection terminals of a connector are simultaneously connected to the first connection terminals of two adjacent functional modules by pressing one connector at a time, the force can be reduced and the operation is more convenient for the user.

[0008] In at least one embodiment, the connecting segment has a flat shape to form a pressing surface on the side of the connecting segment opposite to the functional module, the pressing surface being configured to receive the force of the pressing connector.

[0009] By designing the connecting section into a flat shape, the pressing surface has a certain area, which facilitates the pressing operation of the connector.

[0010] In at least one embodiment, the area of ​​the projection surface of the second connecting terminal along the insertion direction of the connector is greater than the area of ​​the projection surface of the connecting segment along the pressing direction of the connector.

[0011] Since the area of ​​the projection surface of the second connecting terminal along the insertion direction of the connector is larger than the area of ​​the projection surface of the connecting segment along the pressing direction of the connector, the pressing area of ​​the connector is further increased, thereby facilitating the pressing operation of the connector and improving the pressing feel of the connector.

[0012] In at least one embodiment, the first connecting terminal is provided with a first snap-fit ​​portion, and the second connecting terminal is provided with a second snap-fit ​​portion. When the first connecting terminal and the second connecting terminal are plugged in, the first snap-fit ​​portion and the second snap-fit ​​portion snap together.

[0013] By providing the first and second latching parts, the first and second connecting terminals can be kept in contact, thereby improving the problem that the two second connecting terminals of the connector are easily separated from the two first connecting terminals of the adjacent two functional modules after being plugged in, and enhancing the stability of the connection between the connector and the functional modules.

[0014] In at least one embodiment, the functional module includes an inner shell, a first connection terminal disposed in the inner shell, and at least a portion of the first connection terminal exposed on the outside of the inner shell, and a connector located on the outside of the inner shell and plugged into the portion of the first connection terminal exposed on the outside of the inner shell.

[0015] By placing the first connection terminal on the outside of the inner shell, it is easier for the connector to be wired and pressed from the outside of the inner shell, thereby improving the wiring efficiency of multiple functional modules.

[0016] In at least one embodiment, the inner shell is provided with a limiting groove, a first connecting terminal is disposed in a limiting groove, and before the operation of pressing the connector is performed, a second connecting terminal partially extends into the limiting groove, and the groove wall of the limiting groove is limited and engaged with the second connecting terminal so that the second connecting terminal is aligned with the first connecting terminal.

[0017] By setting a limiting groove, on the one hand, the limiting groove can position the first connecting terminal, so as to facilitate the installation of the first connecting terminal onto the inner shell and its electrical connection with the functional module inside the inner shell, thereby improving the assembly efficiency of assembling the first connecting terminal onto the inner shell; on the other hand, before pressing the connector, part of the second connecting terminal extends into the limiting groove, so as to position the second connecting terminal through the limiting groove. Since the first connecting terminal is also located in the limiting groove, it is convenient to position the first connecting terminal and the second connecting terminal, thereby improving the connection efficiency between the second connecting terminal of the connector and the first connecting terminal on the inner shell.

[0018] In at least one embodiment, the inner shell is provided with a relief groove, the relief grooves of two adjacent functional modules are connected, the first connection terminal and the connector are both provided in the relief groove, and the side of the connector away from the first connection terminal is lower than the groove opening of the relief groove or flush with the groove opening of the relief groove.

[0019] By placing the connector within the relief groove, such that the side of the connector away from the first connection terminal is lower than or flush with the opening of the relief groove, the problem of the connector protruding from the opening of the relief groove easily interfering with and damaging the circuit breaker of the power distribution equipment can be improved.

[0020] In at least one embodiment, the inner shell is provided with a handle groove, which is located on one side of the connecting section and communicates with the clearance groove.

[0021] The user's hand can reach from the side through the handle slot between the connecting section and the inner shell to hook up the connecting section and pull out the two first connecting terminals at the same time. This also allows the side wall of the slot to be closer to the connector.

[0022] On the other hand, embodiments of this application provide a power distribution device, including a housing and the aforementioned electrical device, wherein the electrical device is disposed within the housing.

[0023] By incorporating the aforementioned electrical devices into the power distribution equipment, the electrical connection steps between two adjacent functional modules are reduced due to the installation of connectors. This saves wiring time for multiple functional modules, improves the assembly efficiency of electrical connections between multiple functional modules, and thus enhances the assembly efficiency of the power distribution equipment.

[0037] The technical solutions of the embodiments of this application will be described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0038] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0039] The electrical device includes multiple functional modules, which are connected sequentially by wires. In related technologies, each functional module is equipped with a connection part. The two ends of a wire are generally connected to the connection parts of two adjacent functional modules in two separate steps, which results in a long connection time and low connection efficiency of multiple functional modules.

[0040] Embodiments of this application provide an electrical device comprising at least two functional modules and at least one connector. The at least two functional modules are arranged sequentially, and each functional module is provided with two first connection terminals. The connector includes a connecting section and two second connection terminals, which are respectively connected to the two ends of the connecting section. The connecting section is configured to have a generally rigid structure and is electrically connected to the two second connection terminals. A first connection terminal of one functional module and a first connection terminal of an adjacent functional module are configured to be inserted into two second connection terminals of the same connector, respectively. The two first connection terminals connected to the same connector are arranged close to each other, so that the insertion operation of the two second connection terminals and the corresponding two first connection terminals of a connector can be completed simultaneously by pressing the connector once.

[0041] By setting up a connector to electrically connect two adjacent functional modules, the connector includes a generally rigid connecting section and two second connecting terminals. Each functional module includes two first connecting terminals. The generally rigid connecting section connects the two second connecting terminals so that the two second connecting terminals form a whole. This allows the first connecting terminals of two adjacent functional modules to be synchronously aligned with the two second connecting terminals of a connector, facilitating the wiring operation of the two adjacent functional modules. Furthermore, the first connecting terminals of two adjacent functional modules are positioned close together to shorten the overall length of the connector. This allows the two second connecting terminals of a connector to be simultaneously connected to the two adjacent first connecting terminals of two adjacent functional modules by pressing one connector at a time. This reduces the number of operation steps for the two adjacent functional modules, thereby saving wiring time for multiple functional modules and improving the electrical connection efficiency of multiple functional modules.

[0042] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0043] Please see Figure 1 and Figure 2 One embodiment of this application provides an electrical device 100 and a power distribution device 200. The power distribution device 200 includes the electrical device 100 and a housing 201, with the electrical device 100 disposed within the housing 201.

[0044] Understandably, power distribution equipment 200 refers to the general term for various load equipment or devices used in the power system to distribute electrical energy from the main power source (transmission network or substation) to the user end. It plays the role of voltage reduction, distribution, control and protection in the power system and is an important part of power supply.

[0045] Please see Figure 3 In some embodiments, the electrical device 100 includes at least two functional modules 10 and at least one connector 20, with adjacent functional modules 10 connected via a connector 20; please refer to [further details omitted]. Figure 4 and Figure 5 Each functional module 10 is provided with two first connection terminals 11; the connector 20 includes a connection segment 21 and two second connection terminals 22, the two second connection terminals 22 are respectively connected to the two ends of the connection segment 21, the connection segment 21 is configured to have a generally rigid structure and electrically connect the two second connection terminals 22; one first connection terminal 11 of a functional module 10 and one first connection terminal 11 of an adjacent functional module 10 are configured to be inserted into the two second connection terminals 22 of a connector 20 respectively; the two first connection terminals 11 connected to the same connector 20 are arranged close to each other so that the insertion operation of the two second connection terminals 22 and the corresponding two first connection terminals 11 of a connector 20 can be completed simultaneously by pressing the connector 20 once.

[0046] The first connection terminals 11 of two adjacent functional modules 10 are plugged into the two second connection terminals 22 of a connector 20 to facilitate the wiring operation of the two adjacent functional modules 10. Furthermore, the first connection terminals 11 of the two adjacent functional modules 10 are arranged close together to make the overall length of the connector 20 shorter. This allows the plugging operation of one connector 20 into the first connection terminals 11 of the two adjacent functional modules 10 to be completed simultaneously by pressing the two second connection terminals 22 of one connector 20 at once. This application reduces the wiring steps of the two adjacent functional modules 10, thereby saving the wiring time of multiple functional modules 10 and improving the wiring efficiency of multiple functional modules 10.

[0047] The phrase "two first connection terminals 11 connected by the same connector 20 are set close together" means that in two adjacent functional modules 10, the distance between two adjacent first connection terminals 11 is less than or equal to the maximum length of a human hand or a finger, so that the length of the connector 20 is less than or equal to the maximum length of a human hand, so that the connection segment 21 and the two second connection terminals 22 can be pressed simultaneously with one hand or one finger, and the two second connection terminals 22 of a connector 20 can be connected to the two adjacent first connection terminals 11 in two adjacent functional modules 10 with one press.

[0048] The connection segment 21 is configured as having a roughly rigid structure, meaning that the connection segment 21 is not a completely rigid structure. The connection segment 21 can have a certain degree of flexibility. Under the action of external force, the connection segment 21 can undergo elastic or plastic bending deformation and can return to its original shape. The connection segment 21 can maintain its own shape when subjected to a certain pressing force and is not easily deformed or damaged, so that the pressing force can be transmitted from the connection segment 21 to the two second connection terminals 22. Thus, with one press, the two second connection terminals 22 of a connector 20 can be simultaneously connected to the first connection terminals 11 of two adjacent functional modules 10. Furthermore, the user can hold one end of the second connection terminal 22 and drive the other end of the second connection terminal 22 to move against gravity through the connection segment 21. That is, by rotating one end of the second connection terminal 22, the connection segment 21 can drive the other end of the second connection terminal 22, which was originally located on the lower side, to the upper side, and the connection segment 21 can be supported between the two second connection terminals 22.

[0049] Please see Figure 3 In some embodiments, the electrical device 100 is provided with multiple functional modules 10, that is, there are more than two functional modules 10. The multiple functional modules 10 are divided into a main wiring module 110, a communication module 111, and multiple branch modules 112. The main wiring module 110, multiple branch modules 112, and communication module 111 are connected in series through multiple connectors 20 to realize the communication connection between the main wiring module 110, multiple branch modules 112, and communication module 111. This enables the communication module 111 to collect data from multiple branch modules 112 and main wiring module 110 in real time, so as to monitor and analyze the power distribution status of branch modules 112 and main wiring module 110.

[0050] Please see Figure 2 and Figure 3In some embodiments, the electrical device 100 further includes a busbar 113, a main wiring module 110 configured to be electrically connected to a main power supply, and multiple branch modules 112 configured to be electrically connected to multiple load devices. The main wiring module 110 and the multiple branch modules 112 are electrically connected through the busbar 113 so that the multiple branch modules 112 can distribute the power received by the main power supply from the main wiring module 110 to the multiple load devices.

[0051] Multiple branch modules 112 are located between the main wiring module 110 and the communication module 111. Understandably, the busbar 113 is not connected to the communication module 111. By placing the multiple branch modules 112 between the main wiring module 110 and the communication module 111, it is convenient for the multiple branch modules 112 to be electrically connected to the main wiring module 110 through the busbar 113, and the busbar 113 can be kept out of contact with the communication module 111.

[0052] Understandably, the main wiring module 110 and the communication module 111 are located at opposite ends of the housing 201 in the height direction. The wires extend from one end of the housing 201 to achieve electrical connection between the main wiring module 110 and the main power supply. Since the communication module 111 is located at the other end of the housing 201, the wires between the main wiring module 110 and the main power supply will not interfere with the connector 20.

[0053] By setting up multiple functional modules 10, the power distribution equipment 200 becomes a modular power distribution equipment. This allows each functional module in the power distribution equipment 200 to be designed as an independent, interchangeable standard module, which can then be flexibly combined according to actual needs. This approach improves the flexibility, scalability, and ease of maintenance of the power distribution equipment 200.

[0054] Please see Figure 5 and Figure 8 By modularizing multiple functional modules 10, the setting position of the functional modules 10 can be adjusted so that the first connection terminal 11 can be set on the left or right side of the functional module 10, which can improve the flexibility of using multiple functional modules 10.

[0055] The multiple functional modules 10 may also include modules with other functions. The positions of the multiple functional modules 10 can be adjusted according to actual needs. The two second connection terminals 22 of the connector 20 of this application are connected to the first connection terminals 11 of two adjacent functional modules 10, facilitating the disassembly and assembly of the connector 20 and the functional modules 10, thereby simplifying the adjustment of the positions of the multiple functional modules 10. Please refer to... Figure 3 , Figure 4 and Figure 5In some embodiments, the two first connection terminals 11 of the same connector 20 are respectively positioned close to the edge of their respective functional modules 10, so that the two first connection terminals 11 connected by the same connector 20 are positioned close together, thereby reducing the distance between adjacent first connection terminals 11 of adjacent functional modules 10; and the distribution direction of the two first connection terminals 11 of the same connector 20 is parallel to the distribution direction of adjacent functional modules 10. Because the above arrangement reduces the distance between adjacent first connection terminals 11 of adjacent functional modules 10, the overall length of the connector 20 is shorter, thus enabling the simultaneous insertion of the two second connection terminals 22 of one connector 20 with the first connection terminals 11 of two adjacent functional modules 10 by pressing one connector 20 at a time.

[0056] The edge of the functional module 10 refers to the two sides of the functional module 10 distributed along the distribution direction of the multiple functional modules 10.

[0057] Please see Figure 4 and Figure 7 In some embodiments, the connecting segment 21 has a flat shape to form a pressing surface 211 on the side of the connecting segment opposite to the functional module 10. The pressing surface 211 is configured to receive the force applied to the connector 20 and has a certain area to facilitate pressing the connector 20. In some embodiments, in a connector 20, the connecting segment 21 includes a conductor (not shown) and an insulating sleeve 210. The conductor is disposed within the insulating sleeve 210. Both second connecting terminals 22 include conductive terminals and insulating connectors 221. The conductive terminals are disposed within the insulating connectors 221, which are connected to the insulating sleeve 210. The conductive terminals are disposed within the insulating connectors 221 and electrically connected to the conductor of the connecting segment 21. By providing the insulating sleeve 210 and the insulating connector 221, insulation between the conductor and the conductive terminal is achieved, thereby improving the problem of easy electric shock during connector 20 wiring and enhancing the safety of connector 20 wiring operations.

[0058] Understandably, the connecting segment 21 of this application has a flat shape structure, that is, both the conductor and the insulating sleeve 210 of the connecting segment 21 can be set as flat shapes. The overall width of the flat conductor is wider so that the conductor supports the insulating sleeve 210, thereby increasing the rigidity of the entire connecting segment 21. When the connecting segment 21 is pressed, the connecting segment 21 is not easily deformed, which is conducive to the transmission of pressing force from the connecting segment 21 to the two second connecting terminals 22.

[0059] Please see Figure 4 and Figure 7In some embodiments, the area of ​​the projection surface of the second connecting terminal 22 along the insertion direction of the connector 20 is greater than the area of ​​the projection surface of the connecting segment 21 along the pressing direction of the connector 20, so as to further increase the pressing area of ​​the connector 20, thereby facilitating the pressing operation of the connector 20 and improving the pressing feel of pressing the connector 20.

[0060] Please see Figure 3 , Figure 5 and Figure 6 In some embodiments, the functional module 10 includes an inner shell 12, a first connection terminal 11 disposed on the inner shell 12, and at least a portion of the first connection terminal 11 exposed on the outside of the inner shell 12, and a connector 20 located on the outside of the inner shell 12 and connected to the portion of the first connection terminal 11 exposed on the outside of the inner shell 12.

[0061] By placing the first connection terminal 11 on the outside of the inner shell 12, it is convenient for the connector 20 to perform wiring pressing operations from the outside of the inner shell 12, thereby improving the wiring efficiency of multiple functional modules 10.

[0062] The functional module 10 also includes at least one electrical component 13 disposed in the inner shell 12. The first connection terminal 11 is electrically connected to the electrical component 13. Since the second connection terminal 22 of the connector 20 is electrically connected to the first connection terminal 11, the connector 20 is electrically connected to the electrical component 13 of the functional module 10, thereby realizing the series connection of multiple functional modules 10.

[0063] Please see Figure 1 , Figure 2 and Figure 8 In some embodiments, the outer shell 201 includes a shell body 2010 and a shell cover 2011. A busbar 113 is disposed on the bottom wall of the shell body 2010 away from the shell cover 2011. The inner shell 12 has a first shell wall 124. A first connecting terminal 11 is disposed on the first shell wall 124. The first shell wall 124 is located on the side of the inner shell 12 facing the shell cover 2011.

[0064] Understandably, before multiple functional modules 10 are connected sequentially through multiple connectors 20, the housing body 2010 and the housing cover 2011 are separated. By setting the first connection terminal 11 on the first housing wall 124, it is convenient to press the connector 20 from the outside of the housing body 2010, and the connector 20 will not interfere with the busbar 113, so that the structure of the entire power distribution equipment 200 is reasonable.

[0065] In some embodiments, each branch module 112 includes an inner housing 12 and electrical components 13. The power distribution equipment 200 also includes a plurality of circuit breakers (not shown). The plurality of circuit breakers are electrically connected to the electrical components 13 within the plurality of branch modules 112. The plurality of circuit breakers are located outside the inner housing 12 and cover the plurality of connectors 20 to hide the plurality of connectors 20, thereby improving the neatness and aesthetics of the structural arrangement within the housing 201 of the power distribution equipment 200.

[0066] For example, multiple circuit breakers are located on the outside of the first housing wall 124. Since the first housing wall 124 is located on the side of the inner housing 12 facing the housing cover 2011, the multiple circuit breakers will not interfere with the busbar 113 located on the bottom wall of the housing body 2010, so that the arrangement of the multiple circuit breakers is reasonable.

[0067] Please see Figure 5 The electrical component 13 includes a busbar 131 and a circuit board (not shown). The circuit board is located inside the inner housing 12. The busbar 131 is electrically connected to the circuit board. A portion of the busbar 131 is exposed on the outside of the inner housing 12 to facilitate the connection of the circuit breaker to the busbar 131.

[0068] Understandably, by covering multiple circuit breakers with multiple connectors 20, the connectors 20 of this application can be hidden inside the circuit breakers, thereby making the connectors 20 in the power distribution equipment 200 neatly distributed and facilitating the organization and management of the wiring harness in the power distribution equipment 200.

[0069] Please see Figure 5 and Figure 6 In some embodiments, the inner shell 12 is provided with a limiting groove 120, a first connecting terminal 11 is disposed in a limiting groove 120, and before the operation of pressing the connector 20 is performed, the second connecting terminal 22 partially extends into the limiting groove 120, and the groove wall of the limiting groove 120 is limited and engaged with the second connecting terminal 22 so that the second connecting terminal 22 is aligned with the first connecting terminal 11.

[0070] By setting the limiting groove 120, on the one hand, the limiting groove 120 can position the first connecting terminal 11, so as to facilitate the installation of the first connecting terminal 11 onto the inner shell 12 and its electrical connection with the electrical component 13, thereby improving the assembly efficiency of the first connecting terminal 11 onto the inner shell 12; on the other hand, before pressing the connector 20, a portion of the second connecting terminal 22 extends into the limiting groove 120, so as to position the second connecting terminal 22 through the limiting groove 120. Since the first connecting terminal 11 is also located in the limiting groove 120, it is convenient to position the first connecting terminal 11 and the second connecting terminal 22, thereby improving the connection efficiency between the second connecting terminal 22 of the connector 20 and the first connecting terminal 11 on the inner shell 12.

[0071] Please see Figure 4 , Figure 5 and Figure 6 In some embodiments, the first connecting terminal 11 is provided with a first snap-fit ​​portion 121, and the inner shell 12 is provided with a second snap-fit ​​portion 220. When the first connecting terminal 11 and the second connecting terminal 22 are inserted, the first snap-fit ​​portion 121 and the second snap-fit ​​portion 220 snap together so that the first connecting terminal 11 and the second connecting terminal 22 remain inserted, thereby improving the problem that the two second connecting terminals 22 of the connector 20 are easily separated from the two adjacent first connecting terminals 11 of the two adjacent functional modules 10 after insertion, and improving the stability of the connection between the connector 20 and the functional module 10.

[0072] For example, one of the first snap-fit ​​portion 121 and the second snap-fit ​​portion 220 is provided with a snap fastener, and the other of the first snap-fit ​​portion 121 and the second snap-fit ​​portion 220 is provided with a slot. The snap fastener is snapped into the slot to achieve a fixed connection between the connector 20 and the inner shell 12.

[0073] In some embodiments, the connector 20 is provided with two first snap-fit ​​portions 121, which are respectively located on opposite sides of the two second connecting terminals 22. The inner shell 12 is provided with two second snap-fit ​​portions 220, which are arranged in a one-to-one correspondence with the two first snap-fit ​​portions 121, so as to form a connecting line through the two second snap-fit ​​portions 220 and the two first snap-fit ​​portions 121, thereby improving the connection stability between the connector 20 and the inner shell 12.

[0074] Please see Figure 4 , Figure 5 and Figure 6 In some embodiments, the inner shell 12 is provided with a relief groove 122, and the relief grooves 122 of two adjacent functional modules 10 are connected. The first connection terminal 11 and the connector 20 are both provided in the relief groove 122. The side of the connector 20 away from the first connection terminal 11 is lower than the groove opening 1220 of the relief groove 122 or flush with the groove opening 1220 of the relief groove, so as to improve the problem that the connector 20 protruding from the groove opening 1220 of the relief groove 122 is prone to interfering with the circuit breaker of the power distribution equipment 200 and damaging the circuit breaker.

[0075] Understandably, multiple circuit breakers can provide overload protection, short-circuit protection, power isolation, and normal on / off control for multiple branch modules 112, thereby ensuring the stable operation of the power distribution equipment 200 and improving the safety of its operation.

[0076] Please see Figure 4 , Figure 5 and Figure 6In some embodiments, the inner shell 12 is provided with a handle groove 123, which is located on one side of the connecting section 21 and communicates with the relief groove 122. The user's hand can reach between the connecting section 21 and the inner shell 12 through the handle groove 123 to hook up the connecting section 21 and pull out the two first connecting terminals 11. In addition, it can also make the sidewall of the relief groove 122 closer to the connector 20.
