It is to be noted that the features in the following embodiments and examples may be combined with each other without conflict.

It should be noted that the drawings provided in the following embodiments are only for illustrating the basic idea of the present invention, and the drawings only show the components related to the present invention rather than being drawn according to the number, shape and size of the components in actual implementation, and the form, amount and ratio of the components in actual implementation may be changed arbitrarily, and the layout of the components may be more complicated.

Some exemplary embodiments of the invention have been described for illustrative purposes, and it is to be understood that the invention may be practiced otherwise than as specifically described.

As shown in fig. 1 and 2, the present invention provides an electrical connector 10, which connects a battery with an external power source through the electrical connector 10, for charging and discharging the battery, especially for charging and discharging a vehicle-mounted battery. The electrical connector 10 includes a male electrical connector end 100 and a female electrical connector end 200. When in use, the male terminal 100 of the electrical connector is inserted into the female terminal 200 of the electrical connector, thereby realizing the electrical connection between the external power supply and the battery.

As shown in fig. 2, 3 and 5, the male connector end 100 includes a first connection assembly 110 and a receptacle terminal. The socket terminals may include the signal socket terminal 130 and the power socket terminal 120, or may include only the power socket terminal 120, and are set according to actual requirements. The first connecting component 110 serves as a supporting member of the male end 100 of the electrical connector, and is used for carrying other components of the male end 100 of the electrical connector and connecting to the female end 200 of the electrical connector. The first connecting member 110 is provided with a first locking device 140, and when the male connector end 100 is inserted into the female connector end 200, the first locking device 140 cooperates with a second locking device on the female connector end 200 to complete locking, so that the male connector end 100 and the female connector end 200 are fixed together.

The first locking device 140 includes a locking member 141. The locking member 141 is connected with the first connection assembly 110, and the locking member 141 is movable relative to the first connection assembly 110. In some embodiments, the first locking device 140 further comprises an elastic member 144, which is connected to the locking member 141 and the first connecting assembly 110, respectively, and the elastic member 144 can exert an elastic force on the locking member 141, and the elastic force can urge the locking member 141 to move toward the female end 200 of the electrical connector with respect to the first connecting assembly 110 after the male end 100 of the electrical connector is inserted into the female end 200 of the electrical connector, so that the locking member 141 is kept stationary with respect to the second locking device after the locking member 141 is engaged with the second locking device of the female end 200 of the electrical connector. It should be understood that other mechanisms capable of keeping the locking member 141 stationary with respect to the second locking device can be substituted for the elastic member 144 after the locking member 141 is completely engaged with the second locking device, and is not limited to the elastic member 144, for example, a ratchet and rack structure can be used instead of the elastic member. It will also be appreciated that the configurations of the first and second locking means may be interchanged, i.e. it is also possible to arrange the second locking means to comprise a locking member and then arrange the first locking means to a configuration matching the locking member.

In some embodiments, as shown in fig. 5, the locking member 141 is a snap-lock structure. Specifically, the locking member 141 is pivotably connected to the first connection assembly 110. Two opposite protrusions 117 are provided on the first connection assembly 110 with a space between the two protrusions 117, and the locking member 141 is connected between the two protrusions 117 by a pin 142 so that the locking member 141 can rotate relative to the first connection assembly 110. When the male end 100 of the electrical connector is mated with the female end 200 of the electrical connector, in order to allow the locking member 141 to complete locking, a hook 143 is disposed at one end of the locking member 141, and the hook 143 is mated with a second locking device on the female end 200 of the electrical connector, so as to fix the two. The second locking means may be provided as a fitting portion 217 (see fig. 6), and the fitting portion 217 is a protrusion formed to protrude outward from the second connecting assembly 210, and the protrusion matches with the shape of the hook 143, so that the hook 143 can catch the fitting portion 217 by an elastic force. The number of the hooks 143 may be one, two or more according to actual requirements. Meanwhile, the elastic member 144 can exert an elastic force that can urge the hook 143 of the locking member 141 to rotate toward the female terminal 200 of the electrical connector. The elastic member 144 may be selected as a torsion spring (see fig. 5), one end of which is connected to the locking member 141, the other end of which is connected to the first connecting assembly 110, and the torsion spring is sleeved on the pin 142. Of course, the elastic member 144 may be other types of elements, including but not limited to a spring and a leaf spring. A pressing portion is provided at the other end of the locking member 141 opposite to the hook portion 143, and when a user presses the pressing portion, a pushing force can be applied to the locking member 141 to overcome the elastic force of the elastic member 144, so that the locking member 141 and the mating portion 217 are disengaged, and the locking is released. It should be understood that the first locking device 140 may also adopt other structures capable of fixing the male end 100 and the female end 200 of the electrical connector together, such as a latch structure, a spring lock structure, etc., which each include a locking member capable of moving relative to the first connection assembly 110.

When the male end 100 of the electrical connector is inserted into the female end 200 of the electrical connector, the first end 121 of the power plug terminal 120 is inserted into the corresponding jack of the female end 200 before the second end 131 of the signal plug terminal 130, so that the power plug terminal 120 is electrically connected to the corresponding jack before the signal plug terminal 130 is connected to the corresponding jack. The arrangement ensures that the power supply terminal can realize reliable current-carrying connection before the signal terminals of the male terminal and the female terminal are connected, so that the power supply terminal can safely pass current when a charging command or a discharging command is given by a communication signal, and the phenomenon of no connection and ignition is ensured.
