Abstract

The invention relates to a terminal locking piece, a charging seat end cover and a charging seat. The terminal locking piece comprises an elastic piece and a pressing plate. When the elastic piece and the pressing plate are assembled to the charging seat end cover in a limiting mode, at least one end of the elastic piece abuts against the pressing plate. The elastic piece stretches out and draws back so that the pressing plate can move relative to the charging base end cover in the radial direction of the through hole, and therefore the pressing plate can be close to or away from the corresponding through hole. The charging seat end cover comprises a base part and a buckling part located on the base part. The base part is suitable for accommodating the terminal locking piece, and the pressing plate is clamped on the buckling part. The charging seat comprises the terminal locking piece and the charging seat end cover. According to the invention, the movement of the terminal locking piece in the charging seat between the pre-locking position and the final locking position can be effectively ensured.

Description

Technical Field

[0001] The present invention relates to the field of charging, and in particular to a terminal locking member, a charging base cover, and a charging base. Background Art

[0002] In the prior art, a charging base adapted to cooperate with a charging gun is provided on a new energy vehicle, so as to be able to charge a power battery on the new energy vehicle through the charging gun. Generally, the charging base includes a housing, charging terminals disposed in the housing, and a charging base cover and a rear end cover respectively mounted on a port and a rear port of the housing. In order to prevent the charging terminals from axially moving, a terminal locking member is usually further disposed in the housing, and the terminal locking member can move between a pre-locking position and a final locking position. When the terminal locking member is moved to the final locking position, the terminal locking member locks the charging terminals to the charging base to prevent the charging terminals from axially moving. When the terminal locking member is moved to the pre-locking position, the terminal locking member is separated from the charging terminals to allow the charging terminals to axially move. The terminal locking member in the prior art is mounted on the charging base by virtue of its own elastic portion and moves between the pre-locking position and the final locking position. However, the elastic portion of the terminal locking member itself is prone to accidents and fails or breaks. Therefore, it is necessary to improve the terminal locking member in the prior art. Summary of the Invention

[0003] The purpose of the present invention is to provide a terminal locking member, a charging base cover, and a charging base, which can effectively ensure the movement of the terminal locking member between the pre-locking position and the final locking position.

[0004] To achieve the above object, the present invention adopts the following technical solution 1: A terminal locking member for locking a charging terminal of a charging base, the charging base being provided with a through hole allowing the charging terminal to pass through, comprising: a pressing plate, the pressing plate being mounted in the charging base; an elastic member, at least one end of the elastic member abutting against the pressing plate, the elastic member being elastically telescopic along the radial direction of the through hole and disposed in the charging base, so that the pressing plate is movably connected to the charging base, and thus the pressing plate approaches or moves away from the through hole.

[0005] As a further improved technical solution 1 of the present invention, the pressing plate includes a first pressing plate and a second pressing plate, the first pressing plate is provided with a first notch, the second pressing plate is provided with a second notch, and the first notch and the second notch respectively accommodate the charging terminals in different through holes.

[0007] As a first further improved technical solution of the present invention, at least one of the two pressing plates is provided with an extension cylinder for guiding, and the other is provided with a cavity for receiving the extension cylinder.

[0008] As a first further improved technical solution of the present invention, both the first pressing plate and the second pressing plate are provided with long groove portions, and a part of the charging base can slide relative to each other in the long groove portions for positioning.

[0009] As a first further improved technical solution of the present invention, the pressing plate is provided with a buckling portion, and the charging base is buckled and held with the buckling portion for positioning.

[0010] As a first further improved technical solution of the present invention, both the first pressing plate and the second pressing plate are provided with blocking portions, and the blocking portions are arranged at the ends of the buckling portions.

[0011] As a first further improved technical solution of the present invention, the first pressing plate and the second pressing plate are arranged in the same direction and in parallel, and there are two elastic members. One of the elastic members is clamped between the charging base and the first pressing plate, and the other elastic member is clamped between the charging base and the second pressing plate.

[0012] To achieve the above object, the present invention adopts the following second technical solution: A charging base end cover, which includes: a base portion and a buckling portion located on the base portion. The base portion is adapted to accommodate the above-mentioned terminal locking member, and the pressing plate is snap-connected to the buckling portion.

[0013] As a second further improved technical solution of the present invention, the charging base end cover is provided with a convex block portion located on the base portion. When the elastic member expands and contracts, the pressing plate moves relative to the convex block portion.

[0014] As a second further improved technical solution of the present invention, the base portion is provided with a connection port seat, and the other end of the elastic member abuts against the connection port seat.

[0015] To achieve the above object, the present invention adopts the following third technical solution: A charging base, which includes:

[0016] A front base; the above-mentioned charging base end cover, a receiving cavity is formed by connecting between the charging base end cover and the front base; a charging terminal, which penetrates through the through hole from one side of the charging base end cover and is inserted into the front base; and the above-mentioned terminal locking member, which is located in the receiving cavity and is movably installed in the charging base end cover to move between a pre-locking position and a final locking position.

[0017] As a further improved technical solution three of the present invention, during the process of the charging terminal being inserted from the end cover of the charging seat into the front base, the charging terminal pushes the terminal locking piece from the pre-locking position to the final locking position, and the elastic force generated by the elastic deformation of the elastic piece presses the pressure plate against the charging terminal.

[0018] The terminal locking member in the present invention comprises an elastic member independent of the pressure plate, at least one end of the elastic member abuts against the pressure plate, and the elastic member is elastically retracted and arranged in the charging seat along the radial direction of the through hole. The elastic force of the elastic member independent of the pressure plate in the present invention is more durable and effective than the elastic force of the elastic part of the terminal locking member in the conventional technology. The elastic member in the present invention is not easy to fail or break, so it can effectively ensure the movement of the terminal locking member between the pre-locking position and the final locking position.

[0042] Please refer to Figures 1 to 20 As shown, the present invention first discloses a terminal locking member 100 for locking the charging terminal 3 of the charging base 500. The charging base 500 is provided with a through hole 400 allowing the charging terminal 3 to pass through. The terminal locking member 100 includes: a pressing plate 2 and an elastic member 1. The pressing plate 2 is installed in the charging base 500; at least one end of the elastic member 1 abuts against the pressing plate 2, and the elastic member 1 is elastically telescoped along the radial direction of the through hole 400 and is disposed in the charging base 500, so that the pressing plate 2 is movably connected to the charging base 500, and thus the pressing plate 2 can approach or move away from the through hole 400. Secondly, the present invention discloses a charging base end cover 4, which includes: a base portion 40 and a snap portion 401 located on the base portion 40. The base portion 40 is adapted to accommodate the terminal locking member 100 as described above, and the pressing plate 2 is snap-connected to the snap portion 401. Finally, the present invention also discloses a charging base 500, which includes: a front base 5; the charging base end cover 4 as described above, a receiving cavity is formed by connecting between the charging base end cover 4 and the front base 5; a charging terminal 3, passing through the through hole 400 from one side of the charging base end cover 4 and inserted into the front base 5; and the terminal locking member 100 as described above, located in the receiving cavity and movably installed in the charging base end cover 4 to move between a pre-locking position and a final locking position.

[0043] The terminal locking member 100 of the present invention comprises: an elastic member 1 and a pressing plate 2. When the elastic member 1 and the pressing plate 2 are limitedly assembled to the charging seat end cover 4, at least one end of the elastic member 1 abuts against the pressing plate 2. The expansion and contraction of the elastic member 1 enables the pressing plate 2 to move relative to the charging seat end cover 4 along the radial direction of the through hole 400, so that the pressing plate 2 can approach or move away from the corresponding through hole 400. The process of terminal locking of the present invention is that when the charging terminal 3 is inserted into the corresponding through hole 400, the charging terminal 3 pushes the pressing plate 2 away from the corresponding through hole 400 and the elastic member 1 is compressed and has elastic force; when the elastic force of the elastic member 1 is released and extends to push the pressing plate 2 close to the corresponding through hole 400, the charging terminal 3 is locked in the corresponding through hole 400. The process of implementing terminal locking by the terminal locking member 100 of the present invention is simple, stable and reliable. The elastic member 1 in the present invention is not easy to fail or break, and the present invention can effectively ensure the movement of the terminal locking member between the pre-locking position and the final locking position.

[0044] Furthermore, the pressing plate 2 includes a first pressing plate 21 and a second pressing plate 22, the first pressing plate 21 is provided with a first recess 210, the second pressing plate 22 is provided with a second recess 220, and the first recess 210 and the second recess 220 respectively accommodate the charging terminals 3 in different through holes 400. The elastic member 1 is one of one and two. Specifically, the terminal locking member 100 of the present invention includes two specific embodiments (such as specific embodiment 1 and specific embodiment 2 described in detail later). In this way, the structural form of the terminal locking member 100 of the present invention is varied, and different choices can be made according to different needs.

[0045] Further, corresponding to the specific embodiment 1, the first pressure plate 21 and the second pressure plate 22 are arranged back to back in reverse, there is at least one elastic member 1 clamped between the first pressure plate 21 and the second pressure plate 22, and one elastic member 1 exerts an elastic pushing effect on the left and right pressure plates 2 at the same time.

[0046] Furthermore, corresponding to specific embodiment 1, at least one of the two pressure plates 2 (the first pressure plate 21 and the second pressure plate 22) is provided with an extension column 2001 for guiding and the other is provided with a hole 2002 for accommodating the extension column 2001. The arrangement of the extension column 2001 and the hole 2002 ensures that the two pressure plates 2 can only move toward or away from each other in a specific direction (for example, left and right directions).

[0047] Further, corresponding to the specific embodiment 1, each of the first pressing plate 21 and the second pressing plate 22 is provided with a long groove 202 to play a role of sliding limit. Specifically, a part of the charging stand 500 can slide relatively in the long groove 202 to limit the position.

[0048] Further, corresponding to the specific embodiment 1, the pressing plate 2 is provided with a buckling portion 201, and the charging seat 500 is engaged and buckled with the buckling portion 201 to limit the position.

[0049] Further, corresponding to Specific Embodiment 1, both the first pressing plate 21 and the second pressing plate 22 are provided with a blocking portion 203, and the blocking portion 203 is arranged at the end of the buckling portion 201.

[0050] Further, corresponding to Specific Embodiment 2, the first pressing plate 21 and the second pressing plate 22 are arranged in parallel in the same direction, and there are two elastic members 1. One of the elastic members 1 is clamped between the charging base end cover 4 and the first pressing plate 21, and the other elastic member 1 is clamped between the charging base end cover 4 and the second pressing plate 22. Each elastic member 1 only elastically pushes against the pressing plate 2 it is connected to.

[0051] Further, corresponding to Specific Embodiment 2, each of the first pressing plate 21 and the second pressing plate 22 is provided with a blocking portion 203 to play a role of sliding limit.

[0052] Please refer to Figures 1 to 20 as shown, a charging base end cover disclosed by the present invention includes:

[0053] A base portion 40 and a buckling portion 401 located on the base portion 40. The base portion 40 is adapted to accommodate the terminal locking member 100 as described above, and the pressing plate 2 is snap-connected to the buckling portion 401. Further, the charging base end cover 4 is provided with a bump portion 402 located on the base portion 40. When the elastic member 1 expands and contracts, the pressing plate 2 moves relatively along the bump portion 402. Further, the base portion 40 is provided with a connection port seat 403, and the other end of the elastic member 1 abuts against the connection port seat 403.

[0054] Please refer to Figures 1 to 20 as shown, a charging base disclosed by the present invention includes:

[0055] A front base body 5; the charging base end cover 4 as described above, and a receiving cavity is formed by connecting between the charging base end cover 4 and the front base body 5; a charging terminal 3, which penetrates through a through hole 400 from one side of the charging base end cover 4 and is inserted into the front base body 5; and the terminal locking member 100 as described above, which is located in the receiving cavity and is movably installed in the charging base end cover 4 to move between a pre-locking position and a final locking position.

[0056] Further, during the process of the charging terminal 3 being inserted into the front base body 5 from the charging base end cover 4, the charging terminal 3 pushes the terminal locking member 100 from the pre-locking position into the final locking position, and the elastic force generated by the elastic deformation of the elastic member 1 presses the pressing plate 2 tightly against the charging terminal 3.

[0057] Please refer to Figures 1 to 20 as shown, the present invention also discloses a charging base 500, including:

[0058] A front base body 5;

[0059] A charging base end cover 4, forming a receiving cavity with the front base body 5;

[0060] A charging terminal 3, which penetrates through a through hole 400 from one side of a charging base end cover 4 and is inserted into a front base body 5; and

[0061] The terminal locking member 100 as described above is located in the receiving cavity and is movably arranged on the charging base end cover 4 so as to be able to move between a final locking position and a pre-locking position. During the process of inserting the charging terminal 3 from the charging base end cover 4 into the front base body 5, the charging terminal 3 can push against the terminal locking member 100 to move from the final locking position into the pre-locking position, and the elastic member 1 is compressed to have an elastic force; when the elastic force of the elastic member 1 is released and the terminal locking member 100 returns from the pre-locking position to the final locking position, the charging terminal 3 can be held in the receiving cavity by the terminal locking member 100 to prevent the axial movement of the charging terminal 3 in the receiving cavity. The charging base 500 of the present invention can secondarily lock the charging terminal 3 in the correct position through the terminal locking member 100 to prevent accidental detachment.

[0062] Furthermore, corresponding to Specific Embodiment 1 and corresponding to Specific Embodiment 2, the charging base end cover 4 includes a base portion 40 and a buckle portion 401 located on the base portion 40. The pressing plate 2 is provided with a buckling position portion 201, and the buckle portion 401 is buckled and held with the buckling position portion 201 for limiting. Therefore, in both Specific Embodiment 1 and Specific Embodiment 2, the pressing plate 2 needs to be held on the charging base end cover 4, but while being held, it is necessary to ensure that the pressing plate 2 can still shift relative to the charging base end cover 4.

[0063] Furthermore, corresponding to Specific Embodiment 1, each pressing plate 2 is provided with a long groove portion 202, and the charging base end cover 4 is provided with a convex block portion 402 located on the base portion 40. When the elastic member 1 expands and contracts, the convex block portion 402 can relatively slide in the long groove portion 202 for limiting. Because both ends of the long groove portion 202 can limit the convex block portion 402, there is a two-way stroke limiting effect in Specific Embodiment 1.

[0064] Furthermore, corresponding to Specific Embodiment 2, each pressing plate 2 is provided with a blocking portion 203 at the end of the buckling position portion 201. When the elastic member 1 extends, the buckle portion 401 can abut against the blocking portion 203 when sliding on the buckling position portion 201 for limiting. Because the blocking portion 203 is arranged at one end of the buckling position portion 201, there is a one-way stroke limiting effect in Specific Embodiment 2.

[0065] Compared with the prior art, the terminal locking member 100 of the present invention includes an elastic member 1 independent of the pressing plate 2. When the elastic member 1 and the pressing plate 2 are assembled to the charging base end cover 4 with limited positions, at least one end of the elastic member 1 abuts against the pressing plate 2. The elastic force of the elastic member 1 in the present invention is more persistent and effective than the elastic force of the self-owned elastic portion of the terminal locking member 100 in the prior art. The elastic member 1 in the present invention is not easy to fail or break. Therefore, the present invention can effectively ensure the movement of the terminal locking member 100 between the pre-locking position and the final locking position, and can secondarily lock the charging terminal 3 in the correct position to prevent accidental detachment.

[0066] The following will be combined with the accompanying drawings of the specification Figures 1 to 13 A specific embodiment 1 of the terminal locking member 100 of the present invention is described.

[0067] Please refer to Figures 1 to 13 As shown, the terminal locking member 100 of the present invention includes: an elastic member 1 and two pressure plates 2. When the elastic member 1 and the pressure plate 2 are limitedly assembled to the charging seat end cover 4, the opposite ends of the elastic member 1 are respectively in contact with a pressure plate 2, and the elastic member 1 is clamped between the two pressure plates 2. The expansion and contraction of the elastic member 1 enables both pressure plates 2 to move relative to the charging seat end cover 4 along the radial direction of the through hole 400, so that both pressure plates 2 can approach or move away from the corresponding through hole 400. The terminal locking member 100 of the present invention includes an elastic member 1 independent of the pressure plate 2, which has a more durable and effective elastic force than the elastic part of the terminal locking member 100 in the conventional technology. The elastic member 1 in the present invention is not easy to fail or break. Therefore, the present invention can effectively ensure the movement of the terminal locking member 100 between the pre-locking position and the final locking position.

[0068] Please refer to Figures 4 to 10 As shown, the pressure plate 2 includes a first pressure plate 21 and a second pressure plate 22, one of the opposite ends of the elastic member 1 abuts against the first pressure plate 21, and the other end of the opposite ends of the elastic member 1 abuts against the second pressure plate 22. There is at least one elastic member 1. In a specific embodiment, the elastic member 1 is only a coil spring; in other embodiments, the elastic member 1 can be two or more coil springs. Regardless of the number of coil springs, the elastic member 1 included in the terminal locking member 100 of the present invention is independent of the pressure plate 2 and is arranged at a symmetrical equilibrium position between the first pressure plate 21 and the second pressure plate 22, and the elastic force provided is more effective and lasting. The focus of the present invention is that the terminal locking member 100 is a terminal locking member (Terminal Positioning Assembly) composed of two pressure plates 2 corresponding to the same elastic member 1 to prevent the axial movement of the charging terminal 3.

[0069] Please refer to Figures 4 to 13 As shown, the first pressing plate 21 and the second pressing plate 22 are both C-shaped, and the two C-shaped plates are arranged back to back with opposite openings. In the specific embodiment, an elastic member 1 is arranged at the center of the back of the C-shaped plate, so that the distance between the elastic member 1 and the two ends of each C-shaped plate is equal. When one of the pressing plates 2 is subjected to the pressure from the charging terminal 3, the elastic member 1 can be compressed toward the direction of the other pressing plate 2. Please refer to Figure 9When the first pressing plate 21 is subjected to the pressing force from the charging terminal 3, it can compress the elastic member 1 in the right direction where the second pressing plate 22 is located; when the second pressing plate 22 is subjected to the pressing force from the charging terminal 3, it can compress the elastic member 1 in the left direction where the first pressing plate 21 is located. Therefore, the focus of the present invention also lies in that: the present invention has and only has a unique terminal locking member 100, and two charging terminals 3 share one terminal locking member 100.

[0070] Please refer to Figure 9 and Figure 10 As shown, one of the two pressing plates 2 is provided with an extending cylinder 2001 for guiding and the other is provided with a cavity 2002 for receiving the extending cylinder 2001. With such a setting, when one of the pressing plates 2 (for example, the first pressing plate 21) is subjected to the pressing force from the charging terminal 3 and can compress the elastic member 1 in the direction of the other pressing plate 2 (for example, the second pressing plate 22), the extending cylinder 2001 can change the penetration depth in the cavity 2002. During the process of the elastic member 1 expanding and contracting and the depth of the extending cylinder 2001 changing, when the two pressing plates 2 approach or move away from each other, they will not deviate in the up and down directions. That is, the setting of the extending cylinder 2001 ensures that the two pressing plates 2 can only move closer or farther away from each other in the left and right directions.

[0071] Please refer to Figures 6 to 12 As shown, each front surface of the pressing plate 2 facing away from the charging seat end cover 4 is provided with a buckling portion 201 for facilitating the buckling of the charging seat end cover 4. The buckling portion 201 is for snap-fastening with the snap portion 401 provided on the charging seat end cover 4. Please pay special attention to Figure 11 and Figure 12 , when the opposite sides of each pressing plate 2 are snap-fastened to the charging seat end cover 4 by a pair of buckling portions 201, the pressing plate 2 cannot be easily separated from the charging seat end cover 4.

[0072] Please refer to Figures 6 to 12 As shown, each rear surface of the pressing plate 2 is provided with a long groove portion 202 for facilitating the guiding of the movement of the pressing plate 2 relative to the charging seat end cover 4. Please pay special attention to Figures 10 to 12 , the charging seat end cover 4 is provided with a convex block portion 402, and the convex block portion 402 can slide relative to the long groove portion 202 for limiting. Therefore, when the elastic member 1 expands and contracts, the sliding stroke of the pressing plate 2 that can be pushed is limited within a certain range.

[0073] The following will introduce the specific embodiment 2 of the terminal locking member 100 of the present invention in conjunction with the Figures 14 to 20 description drawings of the specification.

[0074] Please refer to Figures 14 to 20As shown, the terminal locking member 100 of the present invention includes: an elastic member 1 and a pressure plate 2. When the elastic member 1 and the pressure plate 2 are limitedly assembled to the charging seat end cover 4, one end of the elastic member 1 abuts against the pressure plate 2 and the other end of the elastic member 1 can abut against the charging seat end cover 4 (the elastic member 1 specifically abuts against the protruding portion on the base 40 of the charging seat end cover 4). The elastic member 1 can be clamped between the pressure plate 2 and the charging seat end cover 4, and the expansion and contraction of the elastic member 1 enables the pressure plate 2 to move relative to the charging seat end cover 4 along the radial direction of the through hole 400, so that the pressure plate 2 can move closer to or away from the corresponding through hole 400. The terminal locking member 100 of the present invention includes an elastic member 1 independent of the pressure plate 2, which is more durable and more effective than the elastic force of the elastic part of the terminal locking member 100 in the conventional technology. The elastic member 1 in the present invention is not easy to fail or break. Therefore, the present invention can effectively ensure the movement of the terminal locking member 100 between the pre-locking position and the final locking position.

[0075] Please refer to Figures 14 to 20 As shown, there are two elastic members 1 and two pressure plates 2, and the elastic member 1 includes a first elastic member 11 and a second elastic member 12. In a specific embodiment, the two elastic members 1 are coil springs. The pressure plate 2 includes a first pressure plate 21 and a second pressure plate 22. The first elastic member 11 can be clamped between the first pressure plate 21 and the charging seat end cover 4, and the second elastic member 12 can be clamped between the second pressure plate 22 and the charging seat end cover 4. The focus of the present invention is that the terminal locking member 100 is a terminal locking member (Terminal Positioning Assembly) that is composed of a pressure plate 2 corresponding to an elastic member 1 to prevent the charging terminal 3 from moving.

[0076] Please refer to Figures 14 to 20 As shown, the first pressing plate 21 and the second pressing plate 22 are both C-shaped, and the two C-shaped openings are arranged in parallel. Therefore, the focus of the present invention is also: including two terminal locking members 100, each terminal locking member 100 is a terminal locking member (Terminal Positioning Assembly) formed by a pressing plate 2 corresponding to an elastic member 1 to prevent the charging terminal 3 from moving, and each charging terminal 3 has a terminal locking member 100 independently, without interfering with each other.

[0077] Please refer to Figure 17 and Figure 18 As shown, each of the first pressing plate 21 and the second pressing plate 22 is provided with a buckle portion 201. The charging seat end cover 4 is provided with a buckle portion 401, which can be buckled with the buckle portion 201, so that each pressing plate 2 and the charging seat end cover 4 are clamped and limited to each other to prevent separation. When the opposite sides of each pressing plate 2 are buckled and held on the charging seat end cover 4 by a pair of buckle portions 201, the pressing plate 2 cannot be easily separated from the charging seat end cover 4.

[0078] Please continue to refer to Figure 17 and Figure 18 As shown, each of the first pressing plate 21 and the second pressing plate 22 is provided with a blocking portion 203 at the end of the buckling portion 201. When the buckling portion 401 slides on the buckling portion 201, it can abut against the blocking portion 203 for limiting. Therefore, when the elastic member 1 elastically expands and contracts, the sliding stroke of the pressing plate 2 can be limited within a certain range. When the buckling portion 401 abuts against the blocking portion 203, the sliding of the pressing plate 2 in the radial direction of the through hole 400 of the charging base end cover 4 stops.

[0079] Please refer to Figures 1 to 20 As shown, the present invention also relates to a charging base 500, which includes: a front base 5; a charging base end cover 4, forming a receiving cavity with the front base 5; a charging terminal 3, passing through the through hole 400 from one side of the charging base end cover 4 and inserted into the front base 5; and a terminal locking member 100 of the above two specific embodiments (specific embodiment 1 and specific embodiment 2). The terminal locking member 100 is located in the receiving cavity and is movably arranged on the charging base end cover 4 to be able to move between a final locking position and a pre-locking position. During the process of the charging terminal 3 being inserted into the front base 5 from the charging base end cover 4, it can push against the terminal locking member 100 to move from the final locking position to the pre-locking position, and the elastic member 1 is compressed and has elastic force; when the elastic force of the elastic member 1 is released and the terminal locking member 100 returns from the pre-locking position to the final locking position, the charging terminal 3 can be held in the receiving cavity by the terminal locking member 100 to prevent the axial movement of the charging terminal 3 in the receiving cavity.

[0080] In summary, the terminal locking member 100 of the present invention includes an elastic member 1 independent of the pressing plate 2. When the elastic member 1 and the pressing plate 2 are assembled to the charging base end cover 4 with limited positions, at least one end of the elastic member 1 abuts against the pressing plate 2. Compared with the elastic force of the self-owned elastic portion of the terminal locking member 100 in the prior art, the elastic force of the elastic member 1 in the present invention is more durable and effective. The elastic member 1 in the present invention is not easy to fail or break. Therefore, the present invention can effectively ensure the movement of the terminal locking member 100 between the pre-locking position and the final locking position.

The understanding of the present invention should be based on those skilled in the art of the relevant technical field. Although this specification has described the present invention in detail with reference to the above embodiments, those of ordinary skill in the art should understand that those skilled in the relevant technical field can still modify the present invention or make equivalent replacements. All technical solutions and their improvements that do not depart from the spirit and scope of the present invention should be covered within the scope of the claims of the present invention.
