For those skilled in the art, the specific meaning of the above terms in the embodiments of this application can be understood according to the specific circumstances.

[0041] In the description of the embodiments of this application, unless otherwise expressly specified and limited, the technical term "contact" should be interpreted broadly, and can be direct contact, contact through an intermediate medium layer, contact between two contacting parties with substantially no interaction force, or contact between two contacting parties with interaction force.

[0042] In related technologies, after the spring is inserted into the base, the battery pins are then inserted into the spring to connect the battery to the battery socket. After connection, the battery socket is soldered to the circuit board to supply power to the circuit board. However, during the insertion of the battery pins into the spring, they may get stuck in the gap between the spring and the base, causing the spring to deform or even break.

[0043] The guide block 300 in this embodiment guides the battery pins, allowing them to move more accurately from the interface 200a into the mating groove 200b. This reduces interference between the battery pins and the spring contact 200, thereby reducing the likelihood of damage to the battery socket.

[0044] This application proposes to provide a battery socket; please refer to [link / reference]. Figures 1 to 7 The battery socket includes a base 100, a spring 200, and a guide block 300. The base 100 has a receiving groove 100a. The spring 200 is partially installed within the receiving groove 100a and is electrically connected to both the battery and a circuit board. The spring 200 has an interconnected interface 200a and a mating groove 200b, allowing the battery pins to move from the interface 200a into the mating groove 200b along a first direction. A gap 200c exists between the end wall of the interface 200a and the groove wall of the receiving groove 100a. The guide block 300 is mounted on the base 100 and is at least partially located on the side of the interface 200a opposite to the mating groove 200b. Projected along the first direction, the projection area of ​​the guide block 300 covers the projection area of ​​the gap 200c.

[0045] The reed 200 refers to the structure used to make the battery and the circuit board electrically connected. The reed 200 is made of a conductive material.

[0046] It should be noted that the first direction is unidirectional, extending from the interface 200a towards the docking groove 200b. The battery can be removed from the docking groove 200b in a direction opposite to the first direction. The first direction is as follows... Figure 1 The direction indicated by the middle arrow R1.

[0047] For example, when projected along the first direction, the projection area of ​​the mating buckle and the mating groove 200b is approximately rectangular.

[0048] In this embodiment of the application, the projection area of ​​the guide block 300, projected along the extension direction of the receiving groove 100a, covers the projection area of ​​the gap 200c. During battery installation, the battery pins can be accurately moved into the mating groove 200b of the spring 200 under the guidance of the guide block 300, thereby achieving electrical connection between the battery and the battery socket. The battery socket is then mounted on the circuit board, enabling the battery to supply power to the circuit board. The spring 200 is typically a thin metal sheet; guiding the battery with the guide block 300 reduces collisions between the battery and the spring 200, thus reducing the risk of damage to the battery socket.

[0049] In one embodiment, please refer to Figure 4 The guide block 300 has a guide groove 300a, which is connected to the mating interface 200a. Along the first direction, the guide groove 300a gradually tilts toward the central axis of the mating groove 200b.

[0050] For example, along the first direction, the opening size of the guide groove 300a gradually decreases. The central axis of the guide groove 300a overlaps with the central axis of the mating interface 200a and the central axis of the mating groove 200b.

[0051] In this embodiment of the application, the battery pins can gradually move along the guide groove 300a from the larger opening end towards the smaller opening end, thereby moving into the mating groove 200b and realizing the interconnection between the battery and the spring 200. The guide groove 300a can further guide the battery, so that the battery can move quickly into the guide groove 300a, increasing the battery assembly efficiency.

[0052] It is understood that the embodiments of this application are not limited to the guide groove 300a gradually tilting towards the central axis of the docking groove 200b along the first direction. Exemplarily, the opening size of the guide groove 300a along the first direction remains unchanged.

[0053] In one embodiment, please refer to Figure 4 The base 100 has a first stepped surface 100h, a second stepped surface 100i, and a connecting surface 100j. The second stepped surface 100i is located on the side of the first stepped surface 100h facing the docking groove 200b. The connecting surface 100j is connected to the first stepped surface 100h and the second stepped surface 100i respectively. The docking interface 200a is located between the first stepped surface 100h and the second stepped surface 100i along the first direction. The guide block 300 is partially located between the spring 200 and the connecting surface 100j.

[0054] For example, when the guide block 300 is installed on the base 100, the guide block 300 contacts the second step surface 100i along the first direction.

[0055] In the embodiment of this application, the second step surface 100i is located on the side of the first step surface 100h facing the docking groove 200b. When the guide block 300 is installed on the base 100, the guide block 300 is partially located between the spring 200 and the connecting surface 100j. The spring 200, the second step surface 100i, and the connecting surface 100j can position and limit the guide block 300, thereby enabling the guide block 300 to be installed on the base 100 more accurately and quickly.

[0056] In one embodiment, please refer to Figure 6 and Figure 7 The guide block 300 includes a hook 310, and the base 100 is formed with a groove 100b and an abutment portion 100c located in the groove 100b. When the hook 310 is located in the groove 100b, the hook 310 partially abuts against the abutment portion 100c on one side of the abutment portion 100c along a first direction.

[0057] For example, the guide block 300 also includes a guide body 330, and a hook 310 is connected to one side of the guide body 330 along the first direction.

[0058] It is understood that at least one of the latch 310 and the abutment portion 100c can undergo elastic deformation. When the latch 310 and the abutment portion 100c are in contact, one of them undergoes elastic deformation, thereby enabling the latch 310 to engage with the abutment portion 100c. The latch 310 is partially located on one side of the abutment portion 100c along the first direction.

[0059] For example, the guide block 300 has two guide grooves 300a arranged along the second direction, each guide groove 300a corresponding to a battery pin. The hook 310 is located between the two guide grooves 300a along the second direction. When the hook 310 abuts against the abutting part 100c, the hook 310 is close to the middle of the guide block 300, which makes the connection between the guide block 300 and the base 100 more stable.

[0060] In the embodiment of this application, when the hook 310 and the abutment portion 100c engage with each other, the abutment portion 100c can prevent the hook 310 from moving out of the slot 100b in the direction opposite to the first direction, thereby limiting the movement of the guide block 300. The connection between the guide block 300 and the base 100 is relatively stable, and the guide block 300 can press the spring 200 into the receiving groove 100a, thereby limiting the spring 200 in the direction opposite to the first direction.

[0061] It is understood that the embodiments of this application do not limit whether the guide block 300 is provided with a hook 310. Exemplarily, the guide block 300 and the base 100 can be magnetically connected to limit the movement of the guide block 300.

[0062] In one embodiment, please refer to Figure 3 and Figure 7 The guide block 300 also includes a limiting member 340, which is integrally formed with the guide body 330 and protrudes from the guide body 330 along a third direction. The base 100 has a limiting groove 100e adapted to the limiting member 340, which is a through groove extending along a third direction. When the limiting member 340 is located within the limiting groove 100e, the limiting groove 100e can limit the displacement of the limiting member 340 along a second direction, thereby making the guide block 300 more stable during operation.

[0063] For example, a third party to such Figure 3 The direction indicated by the middle arrow R3.

[0064] In one embodiment, please refer to Figure 6 The hook 310 includes a connecting part 311 and a snap-fit ​​part 312 that are connected to each other. The snap-fit ​​part 312 partially contacts the abutting part 100c. The snap-fit ​​part 312 has a first guide surface 312a. Along a first direction, the first guide surface 312a gradually tilts toward the connecting part 311.

[0065] For example, the connecting part 311 and the snap-fit ​​part 312 are integrally formed, and the connecting part 311 is connected to the snap-fit ​​part 312 and the guide body 330 respectively.

[0066] For example, the first guide surface 312a is located on the side of the snap-fit ​​portion 312 that is away from the guide body 330 along the first direction.

[0067] In the embodiment of this application, during the contact between the latching part 312 and the abutting part 100c, the first guide surface 312a contacts the abutting part 100c, and continues to apply a force along the first direction to the latch 310. The first guide surface 312a can slide relative to the abutting part 100c, thereby continuing to move towards the latching groove 100b along the first direction. The first guide surface 312a can guide the movement of the latch 310, thereby reducing interference between the abutting part 100c and the latching part 312. Furthermore, along the first direction, the dimension of the end of the first guide surface 312a facing the connecting part 311 is larger than the dimension of the end away from the connecting part 311, resulting in higher connection strength between the connecting part 311 and the latching part 312, which can reduce the possibility of damage to the latch 310 during installation. The dimension of the end away from the connecting part 311 is smaller and the rigidity is weaker, allowing the latching part 312 to undergo elastic deformation more easily.

[0068] It is understood that the embodiments of this application are not limited to whether the snap-fit ​​portion 312 has a first guide surface 312a. For example, when the first direction is arranged in a vertical direction, the surface of the snap-fit ​​portion 312 on one side along the first direction is a horizontal surface.

[0069] In one embodiment, please refer to Figure 7 The abutment portion 100c has a second guide surface 100f, which is located on the side of the abutment portion 100c away from the slot 100b. The second guide surface 100f gradually slopes towards the central axis of the slot 100b along a first direction, and the slope of the second guide surface 100f is equal to the slope of the first guide surface 312a. The second guide surface 100f can further guide the first guide surface 312a to make the movement of the hook 310 smoother.

[0070] In one embodiment, please refer to Figure 5 The spring 200 includes a socket 210, a connector 220, and a first weld 230. The connector 220 is connected to the first weld 230 and the socket 210 respectively. The socket 210 is partially located in the receiving groove 100a. The interface 200a and the mating groove 200b are both formed in the socket 210. The first weld 230 is used to connect to the circuit board. At least a portion of the structure of the connector 220 extends along a second direction, which is arranged to intersect with the first direction.

[0071] For example, the socket 210, connector 220, and first solder joint 230 are integrally formed, and the spring 200 is approximately U-shaped. After the battery pins are connected to the socket 210, current flows through the connector 220 to the first solder joint 230. After the first solder joint 230 is used for circuit board soldering, the battery is electrically connected to the circuit board.

[0072] For example, the second direction is arranged orthogonally to the first direction, and the connector 220 is located between the socket 210 and the first welded member 230 along the second direction.

[0073] For example, there are two reeds 200, one of which is connected to the positive terminal of the battery, and the other is connected to the negative terminal of the battery. The two reeds 200 are arranged in a third direction, which is orthogonal to both the first and second directions.

[0074] In the embodiment of this application, the connector 220 is connected to both the socket 210 and the first welded member 230, and at least a portion of the structure of the connector 220 extends along a second direction. The relative positions of the socket 210 and the first welded member 230 can be adjusted according to the actual arrangement space. Furthermore, arranging the socket 210 and the first welded member 230 along the second direction can, to some extent, reduce the space occupied by the battery socket along the first direction.

[0075] It is understood that the embodiments of this application do not limit the connection method between the socket 210 and the first welded member 230. Exemplarily, the first welded member 230 is directly connected to the socket 210, and the first welded member 230 and the socket 210 are arranged along a first direction.

[0076] In one embodiment, please refer to Figure 3 The guide block 300 also has a positioning hole 300b, and the first welded part 230 passes through the positioning hole 300b.

[0077] For example, there are two positioning holes 300b, which are arranged at intervals along a third direction, and the two positioning holes 300b correspond to the first welded parts 230 of different springs 200.

[0078] In the embodiment of this application, the first welded component 230 passes through the positioning hole 300b, and the guide block 300 can limit the displacement of the first welded component 230 along the horizontal plane and reduce the cantilever distance of the first welded component 230. After the first welded component 230 is welded to the circuit board, it is difficult for the first welded component 230 to move relative to the circuit board, and the connection strength between the battery socket and the circuit board is high.

[0079] It is understood that the embodiments of this application are not limited to the guide block 300 having a positioning hole 300b for the first welded part 230 to pass through.

[0080] In one embodiment, please refer to Figure 6 The guide block 300 also includes a foolproof element 320 that extends along a first direction. The base 100 forms a foolproof groove 100d that is adapted to the foolproof element 320. When the guide block 300 is installed on the base 100, at least a portion of the structure of the foolproof element 320 is located within the foolproof groove 100d.

[0081] Exemplarily, the anti-misalignment groove 100d and the receiving groove 100a are interconnected and arranged along a second direction. During the installation of the spring 200 along the first direction, the insertion member 210 moves from the mating interface 200a to the mating groove 200b, and the connector 220 and the first welded member 230 move into the anti-misalignment groove 100d. After the guide block 300 is installed, at least a portion of the anti-misalignment member 320 is located within the anti-misalignment groove 100d, and the anti-misalignment member 320 can press the connector 220 so that the connector 220 is clamped by the anti-misalignment member 320 and the base 100, thereby further reducing the possibility of displacement of the spring 200 relative to the base 100.

[0082] For example, the anti-fooling element 320 is connected to the guide body 330, and there are two guide bodies 330. The two anti-fooling elements 320 are arranged at a distance along a third direction. Along the third direction, the hook 310 is located between the two anti-fooling elements 320.

[0083] In the embodiment of this application, the guide block 300 includes a foolproof component 320, and the base 100 forms a foolproof groove 100d that is adapted to the foolproof component 320. The cooperation between the foolproof component 320 and the foolproof groove 100d enables the guide block 300 to be quickly installed and positioned, thereby increasing the assembly efficiency of the battery socket.

[0084] It is understood that the embodiments of this application do not limit whether the guide block 300 is provided with a foolproof element 320.

[0085] In one embodiment, please refer to Figure 2 The battery socket also includes a second welding member 400, one end of which is connected to the base 100, and the other end of which is used for welding to the circuit board.

[0086] For example, the second welded component 400 includes a weld head 410 and a weld pin 420 connected to each other, the diameter of the weld head 410 being larger than that of the weld pin 420. The base 100 has a connecting hole 100g adapted to the weld pin 420, the weld head 410 abutting against one side of the connecting hole 100g along a first direction, and the weld pin 420 engaging with the hole wall of the connecting hole 100g. After the weld pin 420 is welded to the circuit board, the weld head 410 can restrict the displacement of the base 100 along the first direction.

[0087] For example, the number of second weldment 400 is at least two, and the plurality of second weldment 400 are arranged at intervals along a third direction, which can further increase the connection strength between the base 100 and the circuit board.

[0088] In the embodiments of this application, the base 100 is fixedly connected to the circuit board by the second welding component 400, which enables a high connection strength between the base 100 and the circuit board. Furthermore, the welding connection can be completed by a welding device, resulting in a high degree of automation and high assembly efficiency during the assembly process.

[0089] It is understood that the embodiments of this application do not limit the connection method between the base 100 and the circuit board. Exemplarily, the base 100 and the circuit board are connected by expansion screws, which pass through the base 100 and the circuit board to achieve a fixed connection between the base 100 and the circuit board.

[0090] This application also proposes to provide an electricity meter, which includes a body and a circuit board assembly. The circuit board assembly is electrically connected to the body.

[0091] As is understandable, an electricity meter is an instrument used to measure electrical energy; it is also called a kilowatt-hour meter, a power meter, or a kilowatt-hour meter, referring to instruments that measure various electrical quantities. An electricity meter contains a circuit board and is electrically connected to an external power source to realize its main functions. The meter also requires a built-in battery to provide power to the circuit module that maintains the measured data in the event of an external power outage.
