Description

Technical Field

[0001] The utility model relates to the field of connectors, in particular to a connector housing with a secondary locking structure. Background Art

[0002] The structure of the connector is composed of a plug part and a socket part. The signal or current transfer can be realized by plugging the plug part and the socket part together. During the operation and use of the connector, the connector may be affected by external impact and shaking due to being placed in different working conditions, which may cause the plugging structure of the connector to automatically disengage and unlock. Therefore, in order to avoid such situations affecting the working state of the connector, the prior art provides a locking mechanism on the connector to prevent the plug part and the socket part of the connector from automatically unlocking due to accidents.

[0003] However, some connectors equipped with locking mechanisms in the prior art have relatively complex structural designs of the locking mechanisms, which results in relatively high manufacturing and assembly costs for the entire connector, and such complex locking structures are also inconvenient to operate. Utility Model Content

[0004] In order to overcome the above-mentioned shortcomings, the utility model provides a technical solution that can solve the above-mentioned problems.

[0005] A connector housing with a secondary locking structure comprises a housing and a base;

[0006] A first locking assembly for locking the shell and the base together is provided at the inner lower part of the shell, and a second locking assembly for locking the shell and the base together is provided at the inner middle part of the shell;

[0007] The first locking component includes a plurality of hooks arranged at the lower part of the shell, the upper ends of the hooks and the inner wall of the shell are connected to each other and the lower parts are arranged with a gap and inclined to each other, a plurality of sockets corresponding to the hooks are opened on the base, a soft pad is arranged on the outer side of the upper end of the base, and the base and the shell are inserted into the sockets correspondingly through the hooks, so that the base and the shell are limited and matched with each other and the soft pad is squeezed.

[0008] As a further solution of the utility model: the second locking component includes a limiting hook arranged at the upper end in the middle of the front and rear sides of the base, a locking groove is arranged on the inner wall of the shell corresponding to the limiting hook, an inverted Y-shaped connecting rod is rotatably arranged inside the shell, a pressing part is arranged at the upper end of the connecting rod, the pressing part protrudes outward from the shell, and a locking part is arranged at the lower end of the connecting rod, the locking part and the limiting hook are mutually limited, and a spring is arranged between the side of the locking part away from the working end and the shell.

[0009] As a further solution of the utility model: a locking tooth is arranged on the outer side of the locking portion, and a locking groove matched with the locking tooth is arranged on the inner side of the limiting hook.

[0010] As a further solution of the utility model: an anti-slip layer is provided on the outer side of the pressing part.

[0011] Compared with the prior art, the utility model has the following beneficial effects: by providing the first locking assembly and the second locking assembly between the housing and the base, it is possible to prevent the connector from being unlocked due to accidental or mis-touch during use;

[0012] 1. Insert the base upward into the shell, and insert the hooks into the corresponding sockets. By utilizing the characteristics of the hook's own material, the hook and the socket can be elastically limited and matched with each other. With the addition of a soft pad, the tightness of the connection can be effectively improved.

[0013] 2. By inserting the limit hook of the base upward into the lock groove, after contacting the locking part of the connecting rod, the locking part realizes limit cooperation with the limit hook under the action of the spring, thereby realizing a close connection between the base and the shell and improving stability.

[0014] Additional aspects and advantages of the present invention will be given in part in the following description, and in part will become apparent from the following description, or will be learned through the practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] See also Figure 1 , a connector housing with a secondary locking structure, comprising a housing 1 and a base 2;

[0024] A first locking component for locking the housing 1 and the base 2 together is provided at the inner lower part of the housing 1, and a second locking component for locking the housing 1 and the base 2 together is provided at the inner middle part of the housing 1;

[0025] The first locking component includes a plurality of hooks 3 arranged at the lower part of the shell 1, the upper ends of the hooks 3 and the inner wall of the shell 1 are connected to each other and the lower parts are arranged at an angle with a gap between each other, a plurality of sockets 4 corresponding to the hooks 3 are opened on the base 2, and a soft pad 5 is arranged on the outer side of the upper end of the base 2, and the base 2 and the shell 1 are inserted into the sockets 4 respectively through the hooks 3, so that the base 2 and the shell 1 are limited and matched with each other and the soft pad 5 is squeezed.

[0026] When in use, the base 2 is inserted upward into the shell 1, and the hooks 3 are inserted into the corresponding sockets 4 respectively. By utilizing the characteristics of the material of the hook 3 itself, the hook 3 and the socket 4 can be elastically limited and matched with each other, and the cushion 5 can effectively improve the tightness of the connection; when the base 2 needs to be separated from the shell 1, the hook 3 is pushed away to the outside of the contact with the socket 4, and the elastic force of the cushion 5 is utilized to make the hook 3 retract upward into the socket 4, thereby realizing a one-time separation of the base 2 and the shell 1.

[0027] As a further solution of the utility model: the second locking component includes a limiting hook 6 arranged at the upper end of the middle part of the front and rear sides of the base 2, and a locking groove 7 is arranged on the inner wall of the shell 1 corresponding to the limiting hook 6. An inverted Y-shaped connecting rod 8 is rotatably arranged inside the shell 1, and a pressing portion 9 is arranged at the upper end of the connecting rod 8. The pressing portion 9 protrudes outward from the shell 1, and a locking portion 10 is arranged at the lower end of the connecting rod 8. The locking portion 10 and the limiting hook 6 are mutually limited, and a spring 11 is arranged between the side of the locking portion 10 away from the working end and the shell 1.

[0028] By inserting the limiting hook 6 of the base 2 upward into the locking groove 7, after contacting the locking portion 10 of the connecting rod 8, the locking portion 10 realizes limiting cooperation with the limiting hook 6 under the action of the spring 11, thereby realizing a tight connection between the base 2 and the shell 1; when it is necessary to separate the base 2 from the shell 1, the pressing portion 9 is squeezed inwardly, and the rotation cooperation between the connecting rod 8 and the shell 1 is utilized to make the locking portion 10 move outward away from the limiting hook 6, so that the locking portion 10 is separated from the limiting hook 6, thereby realizing a secondary separation of the base 2 and the shell 1.

[0029] As a further solution of the utility model: a locking tooth 12 is arranged on the outer side of the locking portion 10 , and a locking groove 13 matched with the locking tooth 12 is arranged on the inner side of the limiting hook 6 .

[0030] The tightness between the locking portion 10 and the limiting hook 6 can be improved.

[0031] As a further solution of the present invention, an anti-slip layer 14 is provided on the outer side of the pressing portion 9 .

[0032] This can facilitate better squeezing of the pressing portion 9.
