Technology Field

[0001] The present invention relates to a protector for battery terminals, and more specifically, to a protector for battery terminals in which a closing prevention hinge part hinge-connects a body part and an opening / closing cover so that the opening / closing cover can be moved in an open state, thereby improving assembly workability in subsequent processes. Background Technology

[0003] Generally, a battery consists of multiple cells, two terminals, an indicator, etc., and is composed of a positive plate, a negative plate, a separator, an electrolyte, etc.

[0004] Since these batteries lack special insulation, they are significantly affected by heat, especially during the summer. If the battery is left at a high temperature of 60 degrees or higher for a long time, the temperature of the electrolyte rises, causing the active material to separate and the plates to be damaged due to corrosion of the plate grid, which leads to a significant increase in self-discharge.

[0005] Meanwhile, the battery is equipped with a battery terminal cover to protect the two terminals, namely the positive and negative terminals. This battery terminal cover is attached to the positive and negative terminals of the battery, respectively, and serves to prevent the battery from short-circuiting while also preventing the leakage of electrolyte and the intrusion of contaminants to the outside.

[0006] Conventional vehicle battery caps are equipped with an upper cover hinged to the body to allow for opening and closing of the body. However, when fully opened, the hinge portion detaches from the body, and the cover cannot be maintained in an open state. Consequently, the cover is assembled and distributed in a closed state, which significantly reduces assembly workability in subsequent processes.

[0007] Therefore, there is a need to improve this.

Specific details for implementing the invention

[0023] Hereinafter, a battery terminal protector according to an embodiment of the present invention will be described with reference to the attached drawings. In this process, the thickness of the lines or the size of the components shown in the drawings may be exaggerated for clarity and convenience of explanation.

[0024] Furthermore, the terms described below are defined in consideration of their functions in the present invention, and these may vary depending on the intent or practice of the user or operator. Therefore, the definitions of these terms should be based on the content throughout this specification.

[0026] FIG. 1 is a perspective view illustrating the closed state of the opening / closing cover in a battery terminal protector according to one embodiment of the present invention, FIG. 2 is a perspective view illustrating the open state of the opening / closing cover in a battery terminal protector according to one embodiment of the present invention, FIG. 3 is an exploded perspective view illustrating a battery terminal protector according to one embodiment of the present invention, FIG. 4 is an operation diagram illustrating the operation state of the closing prevention hinge part in a battery terminal protector according to one embodiment of the present invention, FIG. 5 is an operation diagram illustrating the operation state of the opening / rotation prevention part in a battery terminal protector according to one embodiment of the present invention, and FIG. 6 is an operation diagram illustrating the operation state of the elastic locking part in a battery terminal protector according to one embodiment of the present invention.

[0028] As illustrated in FIGS. 1 to 6, a battery terminal protector according to one embodiment of the present invention includes a body part (100), an opening / closing cover (200), and an anti-closing hinge part (300).

[0029] The body part (100) has one side open and accommodates a terminal (T) that is inserted into a battery terminal.

[0030] This body part (100) is fixedly installed on the perimeter of the battery and provides a space for accommodating the terminal (T), while also serving to be connected to the opening / closing cover (200) through the anti-closing hinge part (300).

[0031] Of course, the body part (100) is not only made of an insulating material but can also be deformed into various shapes and can be fixed to the periphery of the battery in various ways.

[0032] At this time, the body part (100) is provided with a detachment prevention hook (110) that elastically supports the circumference of the terminal (T) so as to prevent the terminal (T) from detaching when the terminal (T) is received, and a fitting guide hole part (120) is formed so that the terminal (T) received inside is fitted into the battery terminal.

[0033] Additionally, a straight guide tube (130) that guides a wiring (W) electrically connected to a terminal (T) in a straight line may be extended and formed in the body (100). At this time, the straight guide tube (130) is wound around a band cable to be fixed together with the wiring (W), and a detachment prevention projection (131) is formed at the end to prevent the band cable from deviating in the axial direction.

[0034] Accordingly, even if the wiring (W) is wired with a bent path, the portion of the wiring (W) entering the interior of the body part (100) can be arranged in a straight line, so the state of being connected to the terminal (T) can be stably maintained.

[0035] And, the opening / closing cover (200) covers the opening portion of the body part (100) so that it can be opened and closed. This opening / closing cover (200) performs the function of covering the terminal (T) so that the terminal (T) is protected from exposure in the body part (100).

[0036] Of course, the opening / closing cover (200) is made of an insulating material and can be modified into various shapes.

[0037] Meanwhile, the anti-closing hinge part (300) hinges the body part (100) and the opening / closing cover (200) so that the opening / closing cover (200) is prevented from closing arbitrarily while in an open state.

[0038] To this end, the anti-closing hinge portion (300) includes a pair of support brackets (310) protruding from the circumferential surface of the body portion (100), a hinge pin (320) provided between the support brackets (310), a rotating fitting member (330) protruding from the opening / closing cover (200) so as to be rotatably fitted into the circumferential surface of the hinge pin (320), and a locking guide portion (340) that guides the rotating fitting member (330) to be locked or unlocked from the circumferential surface of the hinge pin (320) according to the rotational direction of the rotating fitting member (330).

[0039] Here, the hinge pin (320) includes a first hinge shaft portion (321) that contacts the inner surface of the rotating fitting member (330) and a second hinge shaft portion (322) that is formed with a diameter smaller than the first hinge shaft portion (321) and is spaced apart from the inner surface of the rotating fitting member (330).

[0040] And, the locking guide (340) includes a first locking member (341) that is formed protrudingly on the inner surface of the rotating fitting member (330) to form a locking groove (341a), and a second locking member (342) that is formed protrudingly on the circumferential surface of the second hinge shaft (322) so as to be received in a manner that can be caught in the locking groove (341a).

[0041] Accordingly, when the opening / closing cover (200) is switched from closed to open and the rotating fitting member (330) rotates, if the second locking member (342) is received so as to be caught in the locking groove (341a) by passing the first locking member (341), the rotating fitting member (330) is prevented from rotating against an external force less than or equal to the force passing through the locking groove (341a), so the opening of the opening / closing cover (200) can be stably maintained.

[0042] At this time, when the rotational fitting member (330) is received so that the second locking member (342) is caught in the locking groove (341a), rotation in the opening direction of the opening / closing cover (200) can be prevented by the opening / closing rotation prevention member (350).

[0043] Specifically, the opening rotation prevention part (350) includes a locking support rib (351) formed protruding from the circumferential surface of the body part (100) and a locking stopper (352) formed extending from the opening / closing cover (200) so as to be able to be caught on the locking support rib (351).

[0044] That is, the locking stopper (352) rotates together with the opening / closing cover (200) in the direction of rotation when the opening / closing cover (200) is switched from closed to open, and at the moment the second locking member (342) is received in a way that allows it to be caught in the locking groove (341a), it comes into contact with the locking support rib (351) to restrict the rotation of the opening / closing cover (200).

[0045] Thus, even if a force is applied to rotate the opening cover (200) in the opening direction due to its own weight while it is in the open state, the locking support rib (351) locks and supports the locking stopper (352), so the second locking member (342) can be stably maintained in a state where it can be locked into the locking groove (341a).

[0046] Additionally, the opening / closing cover (200) can be elastically locked to the body part (100) by the elastic locking part (400) when closed.

[0047] The elastic locking part (400) includes a locking projection (410) formed on the inner side of the body part (100) and an elastic locking hook (420) provided on the opening / closing cover (200) to be elastically engaged with the locking projection (410).

[0048] That is, the elastic hook (420) is elastically deformed when it comes into contact with the hook portion (410) during the process of rotating together along the rotational direction of the opening / closing cover (200) when the opening / closing cover (200) is switched from closed to open, and is restored at the moment it passes the hook portion (410) so that the opening / closing cover (200) is prevented from rotating in the opening direction and is supported by being hooked on the hook portion (410).

[0050] Although the present invention has been described with reference to the embodiments illustrated in the drawings, this is merely illustrative, and those skilled in the art will understand that various modifications and equivalent alternative embodiments are possible therefrom.

[0051] Therefore, the true technical scope of protection of the present invention should be determined by the following claims. Explanation of the symbols
