[0031] In order to make the purposes, technical solutions and beneficial effects of the embodiments in the present disclosure clearer, the technical solutions in the embodiments of the present disclosure will be described clearly and completely below in conjunction with the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, rather than all the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the protection scope of the present disclosure.
[0032] As shown in the accompanying drawings, Figures 1 to 10 The large current connector in the embodiment includes a detachable and plug-in male head 1 and a female head 2, and the male head 1 and the female head 2 are internally provided with accommodation spaces for accommodating cables 3 to be connected.
[0033] The male head 1 and the female head 2 are respectively provided with a cover 4 which is detachably fixed to the male head 1 and the female head 2 and covers the accommodation spaces, and the cover 4 is provided on a side facing the accommodation spaces with a limiting part 5 for fixing the cables.
[0034] In the embodiment, the detachable connection between the male head and the female head facilitates the assembly efficiency of the large current connector and reduces the volume of the large current connector, and the limiting part on the cover further limits and fixes the cables in the connector, so that the connection between the cables is more stable.
[0035] The cables 3 on the male head 1 side and the female head 2 side are respectively connected to connection terminals 6, and the connection terminals 6 are respectively recessed in a stepped manner on a side away from a connection end. In a preferred scheme, the limiting part 5 abuts against the step of the connection terminal to prevent the cables 3 from retreating.
[0036] In the exemplary structure, the male head 1 and the female head 2 are provided with hollow recesses 7, and the limiting part 5 is clamped in the recesses 7 and limits the cable 3. Exemplarily, the limiting part 5 is arranged to embrace the lower recess of the connecting terminal 6.
[0037] In the preferred scheme, the male head 1 and the female head 2 are respectively provided with protrusions 8 on two sides of the shell, and the two sides of the cover 4 are respectively provided with clamping holes 9 clamped with the protrusions 8.
[0038] In the preferred scheme, in order to further increase the stability of the connection between the male head and the female head, the male head 1 and the female head 2 are respectively provided with a lock slot 10 and a lock catch 11, and when the male head 1 and the female head 2 are inserted, the lock catch 11 is limited in the lock slot 10 to achieve the fixation of the male head 1 and the female head 2.
[0039] In the more preferred scheme, the lock slot 10 is upwardly raised relative to the male head 1 to form a locking space allowing the lock catch 11 to slide in, and the lock catch 11 is further provided with an inclined surface 13 to assist the sliding into the locking space. The lock catch 11 is further connected with a pressing part 12, and when the pressing part 12 is pressed, the lock catch 11 in the locking space is subjected to a downward force to be released from the locking of the lock slot 10, thereby achieving the unlocking between the male head and the female head.
[0040] In the exemplary structure, the lock catch 11 is arranged on a connecting plate, the first end of the connecting plate is connected with the female head 2, and the second end is connected with the pressing part 12, and the connection between the pressing part 12 and the connecting plate can be provided with a fulcrum connected with the female head 2. After entering the locking space, the first end of the connecting plate abuts against the end of the locking space. When the pressing part 12 is pressed, since the up-and-down movement of the first end of the connecting plate is limited, the lock catch will be subjected to a downward force to move downward and be released from the locking of the lock slot 10, thereby achieving the unlocking between the male head and the female head.
[0041] The above embodiments and application examples are only exemplary descriptions of the present disclosure, and do not limit the scope of the present disclosure. Without departing from the design spirit of the present disclosure, various modifications and improvements of the technical solutions of the present disclosure made by those skilled in the art shall fall within the protection scope of the present disclosure.
