[0014] A preferred embodiment according to the present invention will be described in detail below with reference to the attached drawings.

[0015] The advantages and features of the present invention and the method for achieving them will become clear by referring to the embodiments described in detail below together with the accompanying drawings.

[0016] However, the present invention is not limited by the embodiments disclosed below but may be implemented in various different forms, and these embodiments are provided merely to make the disclosure of the present invention complete and to fully inform those skilled in the art of the scope of the invention, and the present invention is defined only by the scope of the claims.

[0017] In addition, in describing the present invention, if it is determined that related known technologies, etc., may obscure the essence of the present invention, a detailed explanation thereof will be omitted.

[0018] Referring to FIGS. 1 to 6, the high-voltage connector (10) according to the present invention comprises an outer housing (100) having an inner receiving space formed and an outer lever formed, an inner body (210) seated in the receiving space (101) of the outer housing (100) and having a terminal installation space formed on one side so as to allow a terminal (not shown) for transmitting current and signals to be installed, and an inner housing (200) having a shell (150) formed on the outer side of the inner body (210), wherein a part of the shell (150) of the inner housing (200) may form an elastic auxiliary spring (160, 170) and be coupled to and fixed to the lever (110) of the outer housing (100).

[0019] In addition, a sealing member (250) may be combined and provided in the inner housing (200).

[0020] Additionally, a position guarantee member (300) may be attached to the outer housing (100), and the movement of the lever (100) may be restricted by the position guarantee member (300) so as to be fixed.

[0021] Additionally, the elastic auxiliary spring (160, 170) is formed by cutting a part of the shell (150), and the lever (110) of the outer housing (100) has a receiving groove (116) so that the elastic auxiliary spring (160, 170) can be received.

[0022] Additionally, the elastic auxiliary springs are formed by branching out from the shell (150) and may consist of a first elastic auxiliary spring (160) and a second elastic auxiliary spring (170).

[0023] The elastic auxiliary springs (160, 170) are formed by branching out from the shell (150) side by side, but since they are formed in the same shape, only the first elastic auxiliary spring (160) will be described.

[0024] Referring to FIGS. 4 and 5, the first elastic auxiliary spring (160) is formed with a first extension (161) that rises in the direction of the lever (110), a second extension (162) that extends in the front longitudinal direction of the lever (110), a bending part (163) that changes direction in the rear longitudinal direction of the lever (110), and a third extension (164) that extends from the bending part (163), and the third extension (164) is received and fixed in the receiving groove (116) of the lever (110).

[0025] Additionally, the lever (110) is provided with a lever shaft (111) to enable the lever (110) to be locked and unlocked, and a protrusion (115) is formed on the lever shaft (111) in the front longitudinal direction of the lever, and the protrusion (115) may be formed shorter than the length of the lever (110).

[0026] By this, the second extension (162) is supported on the protrusion (115), the bending part (163) is combined in a manner that wraps around one side of the protrusion (115), and the third extension (164) can be stably seated in the receiving groove (116).

[0027] In addition, the second elastic auxiliary spring (170) is also formed with a first extension part (171), a second extension part (172), a bending part (173), and a third extension part (174), and the third extension part (174) can be received and fixed in the receiving groove (116) of the lever (110).

[0028] Since the elastic auxiliary spring is not formed as a single unit but branches out in parallel from the shell (150), it is formed as two first elastic auxiliary springs (160) and second elastic auxiliary springs (170), thereby having the effect of minimizing plastic deformation when coupled to the lever.

[0029] Accordingly, parts of the first elastic auxiliary spring (160) and the second elastic auxiliary spring (170) of the shell (150) can be fixed in a fitting manner to the lever (110), which is the connector main lock configuration, to perform the role of an auxiliary spring.

[0030] That is, it acts as an elastic aid when the connector main lock is operated by borrowing the elastic force of the metal material of the shell (150).

[0031] Accordingly, when the front side of the lever (110) is moved upward and the rear side is moved downward when the connector main lock is operated, it is characterized by the fact that sufficient fastening force and fastening sound can be obtained without requiring a large amount of force to operate due to the elastic force of the elastic auxiliary springs (160, 170) of the shell (150).

[0032] This eliminates the need for a separate rib structure to reinforce the Main Lock.

[0033] In the absence of a rib structure, the locking structure does not become rigid, so no special force is required to unlock it, and it acts as an auxiliary elastic body at the bottom of the main lock, thereby improving the locking force and locking sound when the main lock is locked.

[0034] Referring to FIG. 6, FIG. 6(a) shows the structure of a conventional high-voltage connector, and FIG. 6(b) shows the structure of a high-voltage connector according to the present invention.

[0035] As shown in FIG. 6(a), conventionally, an auxiliary rib (15) shape was added to the main lock lever (11) to reinforce the fastening force and sound of the connector.

[0036] While the structure can reinforce fastening force or fastening sound, the main lock is composed of flame-retardant material, which makes it too rigid and resulted in a side effect of increased connector insertion force.

[0037] Accordingly, as illustrated in FIG. 6(b), according to the present invention, a portion of the elastic auxiliary spring (160, 170) of the shell (150) is fixed in a fitting manner to the lever (110), which is the connector main lock component, to perform the role of an auxiliary spring, thereby reducing plastic deformation of the connector locking part and having the effect of improving the fastening sound due to the role of the elastic auxiliary body.

[0038] That is, even if flame-retardant raw materials that are disadvantageous for forming the main lock in a high-voltage connector are used, a part of the shield shell (150) acts as an auxiliary elastic body, thereby preventing plastic deformation of the locking part, which is a chronic problem of the past, and improving the locking sound.

[0039] Accordingly, according to the present invention, the coupling state can be stably maintained when the connector is coupled, plastic deformation of the locking part of the connector can be reduced, and the coupling sound can be improved.

[0040] Although specific embodiments of the high-voltage connector according to the present invention have been described so far, it is obvious that various modifications are possible within the scope of the present invention.

[0041] Therefore, the scope of the present invention should not be limited to the described embodiments, but should be defined by the claims set forth below as well as equivalents thereof.

[0042] That is, the aforementioned embodiments should be understood as exemplary in all respects and not limiting, and the scope of the invention is defined by the claims set forth below rather than by the detailed description, and all modifications or variations derived from the meaning and scope of the claims and their equivalents should be interpreted as being included within the scope of the invention.
