Fig. 2 is a perspective view showing a general structure of a counterpart member of one embodiment of the present application. Fig. 3 is a perspective view showing a general structure of a connector and an unlocking structure according to an embodiment of the present application, and is a view showing an appearance when the connectors are in a mated state. Fig. 4 is a front view showing a general structure of a connector according to another embodiment of the present application, and is a view showing an appearance when the connectors are in a non-mated state. And is a diagram showing how the connectors are in the unmated state.
As shown in fig. 1, the connector 1 includes a housing 11 and a cover 12 openably and closably attached to one end 11a of the housing 11. The housing 11 has an opening at one end 11a thereof. The housing 11 has a substantially oval shape in plan view, but is not limited thereto, and may have another shape such as a rectangular shape. The X direction indicated by the arrow X in fig. 1 indicates the longitudinal direction of the connector 1, and the direction indicated by the arrow Y indicates the height direction of the connector 1. The direction perpendicular to both the X direction and the Y direction is the thickness direction of the connector 1.
The connector 1 is attached to, for example, a case of a secondary battery, and is used to connect positive and negative electrodes of the secondary battery to an electric device or a charging device outside the battery. The housing 11 is provided with a pair of female terminals 111, for example. The pair of female terminals 111 are arranged in the X direction, for example, and are connected to the positive and negative electrodes of the secondary battery, respectively. A transmission 13 is arranged on the housing 11. Preferably, the transmission structure 13 is provided to a side of the housing 11 having the largest area (i.e., a side parallel to the longitudinal direction X), whereby a space for providing the transmission structure 13 can be secured.
The transmission structure 13 is connected with the cover 12, and the opening and closing state of the cover 12 can be changed along with the change of the motion state of the transmission structure 13. Here, the cover 12 may have various shapes as long as it can cover the opening of the housing 11. The cover 12 is preferably rectangular in shape from the viewpoint of easy connection with the transmission structure 13.
As shown in fig. 2, the mating member 2 is a member that is mated with the connector 1 to achieve mechanical connection and electrical connection. The mating member 2 has a pair of male terminals 22, and the male terminals 22 are engaged with the female terminals 111 to electrically connect the connector 1 and the mating member 2. The pair of male terminals 22 is electrically connected to an external power supply device or an external power consuming device, for example, by a wire harness. Surrounding portions 23 are provided on the outer peripheries of the pair of male terminals 22. The surrounding portion 23 has a shape corresponding to the housing 11 of the connector 1. Longitudinal ribs may be provided around the surrounding portion 23, whereby the coupling force of the connector 1 and the counterpart 2 may be increased. The surrounding portion 23 may further have a connecting portion on an outer side thereof, and the connecting portion may be mechanically connected to a case of the secondary battery. This can prevent the mating member 2 from loosening or falling off after the electrical connection with the connector is made.
An unlocking mechanism 21 is provided on the counterpart 2. The unlocking structure 21 is provided longitudinally on the surrounding portion 23, for example. The unlocking structure 21 may be integrally formed with the surrounding portion 23. The unlocking structure 21 has, for example, a rack. In this way, the transmission structure 13 is driven in the driving direction D by the unlocking structure 21 provided to the counterpart 2 that is mated with the connector 1. The cover 12 is opened by the transmission 13 in an opening direction opposite to the driving direction D. Thereby, it is possible to prevent external dust and other foreign matters from entering therein when the connectors are in the unmated state, and the cover 12 can be automatically opened along with the mating action (insertion action), and since the cover 12 is opened upward, dust and other foreign matters deposited on the cover 12 do not fall into the inside of the connector 1.
In some embodiments, when the connector 1 is mated with the mating member 2, the unlocking structure 21 is inserted into the transmission structure 13 to drive the transmission structure 13, and the transmission structure 13 transmits power to the cover 12 to open the cover 12. When the connector 1 is misaligned with the mating member 2, the unlocking structure 21 is pulled out from the transmission structure 13 to drive the transmission structure 13 in the opposite direction, and the transmission structure 13 transmits power to the cover 12 in the opposite direction to close the cover 12. Thus, the opening of the cover in the mated state and the closing of the cover in the unmated state can be reliably achieved.
In some embodiments, the transmission structure 13 includes a gear structure 131 and a link 132. The gear structure 131 is formed by a combination of gears made of a metal material, a resin material, or the like. The axial direction of the gear structure 131 is perpendicular to the X-direction and the Y-direction. The link 132 is a rod-shaped member made of a metal material, a resin material, or the like. The link 132 is movable in a plane constituted by the X direction and the Y direction.
The cover 12 is connected to the gear structure 131 via a link 132 so that the cover 12 can be opened or closed by the gear structure 131. Specifically, when the gear structure 131 is driven by the unlocking structure 21, the gear structure 131 drives the link 132 to move, and the moving link 132 drives the cover 12 to open or close. Thus, the opening or closing of the cover can be effectively realized with a simple structure by the transmission structure having such a structure.
In some embodiments, when the connector 1 is mated with the mating part 2, the unlocking structure 21 is inserted into the gear structure 131 along the driving direction D and drives the gear structure 131 to rotate, the rotating gear structure 131 drives the connecting rod 132 to move the connecting rod 132, and the moving connecting rod 132 drives the cover 12 to open.
When the connector 1 is misaligned with the mating part 2, the unlocking structure 21 is pulled out from the gear structure 131 in the direction opposite to the driving direction D and drives the gear structure 131 to rotate, the rotating gear structure 131 drives the connecting rod 132 to make the connecting rod 132 move in the opposite direction, and the moving connecting rod 132 drives the cover 12 to close. This makes it possible to more reliably open the cover in the mated state and close the cover in the unmated state.
In some embodiments, one end of the link 132 is rotatably connected with one end of the cover 12. The other end of the link 132 is rotatably connected with the gear structure 131. Rotation of the gear structure 131 moves the link 132, and one end of the link 132 moves the cover 12 outward. That is, the cover 12 slides along the one end 11a of the housing 11 under the traction of the one end of the link 132, and is opened outward. Conversely, in this state, when the gear structure 131 is rotated in the opposite direction, the link 132 is reversely moved, and one end of the link 132 lifts up and closes the cover 12 inwardly. The opening of the cover in the mated state and the closing of the cover in the unmated state can be more reliably achieved.
In some embodiments, gear structure 131 includes 2 gears of first gear 1311 and second gear 1312. The first gear 1311 and the second gear 1312 are aligned in the X direction and are provided so as to be separated from each other with a gap that allows the first gear 1311 and the second gear 1312 to engage with the rack 211.
The unlocking structure 21 includes a rack 211. The rack 211 is an elongated shape having a plurality of teeth on both sides. A plurality of teeth of the rack 211 can be engaged with the first gear 1311 and the second gear 1312. Also, the rack 211 may be formed of a metal material, a resin material, or the like.
Thus, the gear structure and the unlocking structure can be reliably configured with a simple structure by the combination of the first gear, the second gear, and the rack.
In some embodiments, as shown in fig. 1 and 3, the cover 12 is a two-sided, half-open structure including a first cover 121 and a second cover 122 that are half-open. The first cover 121 and the second cover 122 each have a substantially rectangular plate shape and cover the opening of the housing 11.
The first gear 1311 and the first cover 121 are located at one side with respect to the rack 211, and the second gear 1312 and the second cover 122 are located at the other side with respect to the rack 211.
The first cover 121 is connected to the first gear 1311 via a first link 1321, and the second cover 122 is connected to the second gear 1312 via a second link 1322.
Thus, the cover is configured to be split on both sides, and the cover on one side is connected to the gear on one side via the link and the cover on the other side is connected to the gear on the other side via the link, whereby the opening of the cover in the mated state and the closing of the cover in the unmated state can be more reliably achieved.
In some embodiments, as shown in fig. 4, the cover 12 is a two-sided, half-open structure including a first cover 121 and a second cover 122 that are half-open. The first cover 121 and the second cover 122 each have a substantially rectangular plate shape and cover the opening of the housing 11.
The first gear 1311 and the first cover 121 are located at one side with respect to the rack 211, and the second gear 1312 and the second cover 122 are located at the other side with respect to the rack 211.
The first cover 121 is connected to the second gear 1312 via a first link 1321, and the second cover 122 is connected to the first gear 1311 via a second link 1322.
Thus, the cover is configured to be split on both sides, and the cover on one side is connected to the gear on the other side via the link and the cover on the other side is connected to the gear on one side via the link, whereby the opening of the cover in the mated state and the closing of the cover in the unmated state can be more reliably achieved.
In some embodiments, the first link 1321 and the second link 1322 are disposed to cross each other when viewed from a direction perpendicular to the driving direction D of the unlocking structure 21 and the direction X in which the first gear 1311 and the second gear 1312 are aligned. The angle at which the first link 1321 and the second link 1322 intersect with each other is not particularly limited as long as transmission to the cover 12 can be achieved. Thus, even if the first link and the second link are long, the first link and the second link can be compactly stored in the connector.
In some embodiments, as shown in fig. 3, the connector 1 further comprises a sealing ring 4 for sealing between the cover 12 and the housing 11. The material of the seal ring 4 may be any of various materials known in the art, and for example, the material of the seal ring 4 may be rubber, resin, or the like. Thereby, the connector can be more reliably sealed to prevent dust and other foreign matter from entering therein.
In addition, an embodiment of the present application also provides a battery, which may include the connector 1 in the foregoing embodiments.
In addition, an embodiment of the present application further provides an electric device, which includes the battery in the foregoing embodiment, and the battery is used for providing power.
The method for charging the battery according to the embodiment of the present application will be described with reference to fig. 5, wherein the detailed description is omitted.
Fig. 5 is a schematic diagram illustrating a charging method of a battery according to an embodiment of the present application. The charging method 3 of the battery according to the embodiment of the application comprises the following steps: providing a battery comprising the connector 1 of the previous embodiments; providing a charging head comprising a mating part 2 with a connector 1; the battery and the charging head are connected to charge the battery, and the cover 12 is gradually opened during the connection of the battery and the charging head. Specifically, the housing 11 of the connector 1 is provided with a pair of female terminals 111, and the pair of female terminals 111 are connected to the positive and negative electrodes of the battery, respectively. The mating member 2 of the charging head has a pair of male terminals 22, and the male terminals 22 are engaged with the female terminals 111 during the connection of the battery and the charging head, thereby enabling the electrical connection between the connector 1 and the mating member 2.
