However, the connection terminals of the battery connector of the current power supply equipment are exposed so that the user can align the corresponding holes of the battery and charge it after connection. However, the exposed connection terminals of the battery connector have sharp edges and electrical problems, which not only make it easy for users to get injured or damage items during operation, but also cause electric shock or affect the transmission of its electrical signals and other related problems.

[0003] Therefore, how to overcome the aforementioned problems related to the battery connector is a technical issue that the applicant needs to solve. Summary of the invention

[0004] The present application provides a battery connector to solve the technical problems of existing battery connectors.

[0005] The present application provides a battery connector for mutual plugging with a docking connector, the docking connector comprising two guide jacks and a plurality of terminal slots, the battery connector comprising a terminal fixing seat, a plurality of connection terminals, at least two guide pins, a first cover, a second cover and an elastic body, the plurality of connection terminals are arranged on the terminal fixing seat and arranged in parallel; the two guide pins are arranged on the terminal fixing seat and are respectively formed on both sides of the plurality of connection terminals; the first cover is covered on one side of the terminal fixing seat; the second cover is covered on the other side of the terminal fixing seat and corresponds to the first cover cover to accommodate the terminal fixing seat, the second cover is provided with a terminal hole for the plurality of connection terminals to extend or retract; the elastic body is arranged between the first cover and the second cover; wherein, in a non-connected state, the plurality of connection terminals are hidden in the second cover, and at least part of the at least two guide pins are exposed outside the second cover, and in a connected state, the plurality of connection terminals can be moved along an axial direction of the at least two guide pins to be exposed outside the second cover.

[0006] When the battery connector of the present application is not connected to the docking connector, the elastic body will keep the first cover body and the second cover body at an appropriate distance, and the connection terminal will be pushed outward so that it is hidden in the second cover body, which can avoid sharp edges and electrical problems. After the battery connector contacts the docking connector, the connection terminal will extend from the terminal hole of the second cover body to dock with the docking connector of the battery for charging and communication. The battery connector is fixed to the docking connector by forming a tightening state and a release state between the guide pin and the guide socket. The present application does not need to change the design of the guide socket of the docking connector, that is, it can add a tightening and anti-loosening function to the original guide pin and its matching guide socket structure. When the battery connector and the battery are in a connected state (such as charging), if the battery connector is directly moved in the direction of exiting the docking connector without proper operation, the ball of the inner guide rod and the docking connector are in a tightening state, which can further reduce the malfunction and cause the battery connector to fall off. When the battery connector moves toward the direction of insertion into the docking connector, the battery connector can be operated to release the ball of the inner guide rod. The force direction is consistent with the insertion direction, which is conducive to installation and can increase the connection safety between the battery connector and the docking connector.

In this connection process, the pushing member 70 pushes against the guide pin 30, so that the ball 35 is located at the release portion 321 of the inner guide rod 32 and presents a state that it can be retracted into the opening 361, and the two guide pins 30 are pushed into the appropriate positions of the two guide holes 91, so that each connection terminal 20 and each terminal slot 92 can reach the desired connection position. When the battery connector 1 and the docking connector 90 of the battery 9 are at the desired connection position, the pushing member 70 no longer pushes against the two guide pins 30 (or reduces the pushing force), so that the ball 35 is fixed to the fastening portion 322 of the inner guide rod 32 and is in a state of protruding from the opening 361 and is fixed to the inner wall of the guide plug hole 91, so that the two guide pins 30 and the two guide plug holes 91 are in a fastening state, and the battery connector 1 is fixed to the docking connector 90 of the battery 9. When the two guide pins 30 and the two guide plug holes 91 are in a fastening state and the battery connector 1 needs to be pulled away from the docking connector 90 of the battery 9, the pushing member 70 pushes against the guide pins 30, so that the ball 35 is located at the release portion 321 of the inner guide rod 32 and is in a state of being retractable into the opening 361, so that each guide pin 30 and each guide plug hole 91 are in a released state, so that the battery connector 1 can be separated from the docking connector 90 of the battery 9.

[0069] Please refer to Figure 5 and Figure 6As shown, by operating the pushing member 70, the push plate 71 is first pressed to move toward the first cover body 40, and the two shafts 72 will move along the axial direction of the shaft hole 44. After the two shafts 72 respectively contact the top ends of the two guide pins 30, the two inner guide rods 32 will be pushed by the two shafts 72 and move axially along the center holes 311 of the two outer guide rods 31. At this time, the two balls 35 will be pulled out from the fastening parts 322 (such as Figure 5 ) moves to the release portion 321 (such as Figure 6 ), the two balls 35 are respectively retracted into the openings 361 of the buckle 36, and the resistance between the balls 35 and the hole walls of the guide holes 91 is reduced, so that the two guide pins 30 can be smoothly inserted into the two guide holes 91.

[0070] See also Figure 7 and Figure 8 As shown, when the battery connector 1 and the docking connector 90 of the battery 9 are in a connected state, the two inner guide rods 32 move toward the direction close to the two shaft rods 72 through the elastic restoring force of each spring 33, and at this time, the two balls 35 are released from the release portion 321 (as shown in FIG. Figure 7 ) moves to be fixed on the fastening portion 322 (such as Figure 8 ), so that the two balls 35 are in a state of protruding out of the opening 361 and are clamped on the inner wall of the guide hole 91, so that the two guide pins 30 and the two guide holes 91 are in a fastened state, thereby improving the connection stability and safety between the battery connector 1 and the docking connector 90.

[0071] Above Figures 5 to 8 The connection method is only a safer connection method. After the battery connector 1 and the docking connector 90 of the battery 9 are brought close enough, the battery connector 1 is operated to make the connecting terminal 20 expose the second cover 50 and penetrate into the terminal slot 92 of the docking connector 90. Therefore, the user can avoid contacting the sharp metal edge of the connecting terminal 20, thereby reducing the possibility of injury, electric shock or damage to the connecting terminal. In another embodiment, the above-mentioned connection process can also be appropriately adjusted to enable the battery connector 1 to achieve the desired function. For example: when connecting, the pushing member 70 is not operated first, and the guide pin 30 is aligned and inserted into the guide hole 91. When the ball 35 contacts the inner wall of the guide hole 91 to increase the resistance, the pushing member 70 is operated to move the ball 35 to the release portion 321 of the inner guide rod 32, so that the guide pin 30 is inserted into the guide hole 91 with lower resistance.

[0072] The above description is only a preferred embodiment of the present application and is not intended to limit the patent scope of the present application. Other equivalent changes that apply the patent spirit of the present application should all fall within the patent scope of the present application.
