Description

Technical Field

[0001] This utility model relates to the field of electricity meter connector technology, and in particular to a flip-type electricity meter connector. Background Art

[0002] Existing flip-type connectors include an energy meter base and a connector body that is hinged to the energy meter base at one end. The energy meter base has multiple wiring terminals, and the connector body has multiple conductive terminals. In order to make the conductive terminals and wiring terminals fit tightly together and reduce the contact resistance between them, elastic elements and other components are usually used to make the two tightly electrically connected.

[0003] The above design scheme complicates the overall structure, leading to an increase in the failure rate. Therefore, the applicant has made a beneficial design and found a way to solve the above problems. The technical solution to be introduced below is generated in this context. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the traditional meter connector design and provide a product with a simple structure and reduced failure rate.

[0005] To solve the above problems, the present invention adopts the following technical solution.

[0006] A flip-type electricity meter connector includes an electricity meter base, a rotatable connector body, and several equally spaced terminals. The electricity meter base has an arc-shaped guide portion that abuts against the front of each terminal. The connector body has a shorting member located between two terminals. The connector body also has a conductive terminal corresponding to each terminal. Each conductive terminal contains a spreading block, a spring, and a ball bearing. The two ends of the spring abut against the spreading block and the ball bearing, respectively, causing the ball bearing to abut against the terminal and the spreading block to expand the conductive terminal outwards.

[0007] Preferably, the power meter base has protrusions on both sides near the upper end, and the protrusions are configured as arc-shaped contact surfaces.

[0008] Preferably, the energy meter base has a cavity for accommodating wiring terminals, the cavity has an arc-shaped relief portion that abuts against the wiring terminals, the relief portion and the guide portion are arranged opposite to each other, the bottom of the cavity has a wiring hole, and the energy meter base has a flip-up anti-theft cover plate located in front of the connector body.

[0009] Preferably, the connector body is provided with a fixing groove for accommodating a protrusion, and the connector body is provided with an inclined limiting part.

[0010] Preferably, the terminal block is provided with a pressure plate that can move back and forth and is located at the outlet of the wiring hole. The pressure plate is provided with a fastening screw and abuts against the terminal block. The top of the terminal block is provided with a pressure bearing part, which is flush with the sides of the relief part and the guide part.

[0011] Preferably, the conductive terminal has a plurality of petals evenly distributed around a dot as the axis, with a gap between the petals, the conductive terminal has a guide groove and abuts against both sides of the pressure bearing part, the conductive terminal has a cavity inside, and the cavity has a reduced diameter part.

[0012] Preferably, the expanding block has a tightening portion that abuts against the reduced diameter portion, and the ball bearings are slidably disposed in the cavity.

[0013] Preferably, the shorting member has outwardly expanding elastic portions on both sides.

[0014] Beneficial effects:

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] In this invention, the spring force not only causes the expanding block to open the conductive terminal, ensuring a stable electrical connection between the conductive terminal and the energy meter, but also ensures that the ball tightly abuts against the wiring terminal, guaranteeing a stable electrical connection between the two. When the connector body is flipped, the guide part prevents the ball from falling off and indirectly lengthens the distance between the ball and the expanding block. The spring force is released, reducing the outward expansion distance of the conductive terminal, thus facilitating easy removal of the energy meter from the connector body. Through the above design, while ensuring the original function described in the background art, the conductive terminal can achieve a stable electrical connection with the wiring terminal by relying on the components within the conductive terminal, without the need for other components to cooperate. This gives the product the advantages of simple structure and reduced failure rate. Attached Figure Description

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0036] In the description of this utility model, it should be understood that the terms "upper", "lower", "left", "right", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0037] In this embodiment of the utility model, "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent three situations: A exists alone, A and B exist simultaneously, and B exists alone. Additionally, the character " / " in this document generally indicates that the preceding and following related objects have an "or" relationship.

[0038] Reference example Figures 1 to 10 A flip-type electricity meter connector includes an electricity meter base 1, an electricity meter base 1 with a rotatable connector body 2, an electricity meter base 1 with a plurality of equally spaced wiring terminals 3, an arc-shaped guide part 11 that abuts against the front of the wiring terminals 3, a connector body 2 with a shorting member 4 located between two wiring terminals 3, a connector body 2 with a conductive terminal 5 corresponding to the wiring terminal 3, a supporting block 51, a spring 52 and a ball 53 inside the conductive terminal 5, the two ends of the spring 52 abut against the supporting block 51 and the ball 53 respectively, so that the ball 53 abuts against the wiring terminal 3, and the supporting block 51 expands the conductive terminal 5 to the surrounding area;

[0039] It is worth mentioning that protrusions 12 are provided on both sides of the electricity meter base 1 near the upper end. The protrusions 12 are set as arc-shaped contact surfaces 13. The protrusions 12 prevent the connector body 2 from detaching from the electricity meter base 1. The contact surfaces 13 cause the connector body 2 to retract towards the middle, so that the connector body 2 detaches from the electricity meter base 1.

[0040] It is worth mentioning that the energy meter base 1 is provided with a cavity 14 for accommodating the wiring terminal 3. The cavity 14 is provided with an arc-shaped relief part 15, which abuts against the wiring terminal 3. The relief part 15 is arranged opposite to the guide part 11. The bottom of the cavity 14 is provided with a wiring hole 16. The energy meter base 1 is provided with a flip-up anti-theft cover 6, which is located in front of the connector body 2. The relief part 15 serves to make way for the shorting piece 4. The wiring hole 16 allows the exposed part of the wire to enter the pressure plate 31.

[0041] It is worth mentioning that the connector body 2 is provided with a fixing groove 21 for accommodating the protrusion 12, and the connector body 2 is provided with an inclined limiting part 22. The fixing groove 21 is used in conjunction with the protrusion 12, and the limiting part 22 limits the angle of rotation of the connector body 2.

[0042] It is worth mentioning that the terminal block 3 is provided with a pressure plate 31 that can move back and forth and is located at the outlet of the wiring hole 16. The pressure plate 31 is provided with a fastening screw 32 and abuts against the terminal block 3. The top of the terminal block 3 is provided with a pressure bearing part 33. The pressure bearing part 33 is flush with the sides of the relief part 15 and the guide part 11. By rotating the fastening screw 32, the pressure plate 31 and the terminal block 3 gradually approach each other, thereby pressing the exposed part of the wire onto the terminal block 3. The pressure bearing part 33 is used in conjunction with the shorting part 4 and the ball bearing 53.

[0043] It is worth mentioning that the conductive terminal 5 is provided with a number of petals 54 evenly distributed around the dot as the axis, with a gap between the petals 54. The conductive terminal 5 is provided with a guide groove 55 and abuts against both sides of the pressure bearing part 33. The conductive terminal 5 is provided with a cavity 56, and the cavity 56 is provided with a diameter reduction part 57. The petals 54 help the conductive terminal 5 to expand outward and make stable electrical connection with the energy meter. The guide groove 55 is used in conjunction with the pressure bearing part 33 and the guide part 11 to prevent the ball 53 from falling out of the pressure bearing part 33 and the guide part 11, and provides further rotational guidance for the connector body 2. The diameter reduction part 57 is used in conjunction with the tightening part 511.

[0044] It is worth mentioning that the expansion block 51 is provided with a tightening part 511 and abuts against the reduced diameter part 57. The ball 53 is slidably disposed in the cavity 56. The ball 53 provides support force for the spring 52. The spring 52 releases elastic force to the expansion block 51. The tightening part 511 rises to cooperate with the reduced diameter part 57, thereby causing the valve body 54 to expand and move in all directions.

[0045] It is worth mentioning that the short connector 4 has outwardly expanding elastic portions 41 on both sides, which make the short connector 4 fit tightly against the side wall of the pressure bearing portion 33.

[0046] The working principle of this utility model is described as follows:

[0047] Apply an upward thrust to the anti-theft cover 6 and rotate the anti-theft cover 6 so that it moves away from the front of the connector body 2.

[0048] When a pulling force is applied to the connector body 2, the connector body 2 retracts towards the center due to the influence of the contact part and disengages from the protrusion 12. As the connector body 2 is gradually rotated, the ball 53 moves from the top of the pressure part 33 to the guide part 11. The ball 53 gradually moves away from the expansion block 51, and the elastic force of the spring 52 is released. The elastic force of the spring 52 cannot support the tightening part 511 to continue to expand the diameter reduction part 57. Therefore, the flap 54 will retract towards the axis, reducing the contact area and connection tightness between the conductive terminal 5 and the energy meter, making it easy for the energy meter to be easily pulled out from the connector body 2.

[0049] At the same time, the shorting piece 4 enters between the two terminals 3, and the elastic part 41 fits tightly against the side wall of the terminal 3. Thus, the replacement and disassembly of the electricity meter can be completed without interrupting the power supply through the above operation steps.

[0050] The above design scheme can enable the product to achieve the advantages of simple structure and reduced failure rate.

[0051] The above description, in conjunction with specific embodiments, provides a further detailed explanation of the present utility model. It should not be construed that the specific implementation of the present utility model is limited to these descriptions. For those skilled in the art, several simple deductions or substitutions can be made without departing from the concept of the present utility model, and all such deductions or substitutions should be considered to fall within the scope of protection defined by the claims submitted by the present utility model.
