Description

[Detailed description of the invention] The present invention relates to a structure for preventing rotation of connection terminals, and is particularly useful for preventing rotation of crimp terminals in order to effectively use the mounting space when a UP type fuse is used. be.

A general method of fixing a conventional crimp terminal using a UP type fuse is shown in FIG.

That is, on the back side of the fuse socket 1, a screw hole is provided in the copper plate 2 so that an electrical connection can be made.

For wiring, two crimp terminals 4, 4, etc. are connected using the screw holes using the tightening screws 3.

In this case, in order to prevent the crimp terminals 4 from protruding into the back space of the fuse socket 1, we would like to mount them facing each other, with the wired parts 5 of the crimp terminals 4 facing toward the center of the back space. In this case, the crimp terminals 4 having the required wire diameter may come into contact with each other and cause a short circuit.

Therefore, in order to prevent the crimp terminal 4 from protruding from the space on the back side of the fuse socket 1 as much as possible, the attached wire portion 5 should be 90 degrees from the base.
Although crimp terminals 4 and the like bent upward are provided with wired portions 5 facing outward as shown in FIG. 1, they still protrude from the fuse socket 1 to a large extent.

Further, since the fuse socket 1 does not have a rotation prevention mechanism, the range in which the crimp terminal 4 can rotate must be secured as the mounting space of the fuse socket 1.

Although the fuse socket itself has become smaller in size, the actual installation space cannot take advantage of this reduction in size due to the mounting of crimp terminals, etc.

An object of the present invention is to eliminate the above-mentioned drawbacks of the prior art, to securely and easily fix a crimp terminal within the mounting space of a fuse socket, and to improve the efficiency of the mounting space.

Of course, the present invention is not limited to this fuse socket, but can also be applied to other devices having similar problems.

Its unique feature is that it uses a metal fitting to prevent the terminal from turning, and by securing this metal fitting with a tightening screw, the terminal, such as the crimp terminal mentioned above, will not protrude from the mounting surface such as the back of the fuse socket. At the same time as preventing rotation, the metal fittings themselves are also prevented from rotating.

Hereinafter, one embodiment of the present invention will be described with reference to FIG. 2.

This embodiment shows a case where a crimp terminal is fixed in a fuse socket, as in the case of FIG. 1 above.

In this structure, reference numeral 6 denotes a metal fitting for preventing rotation of the terminal, which is formed into a U-shape as a whole, and protrudes in a substantially triangular shape from one side of the horizontal portion of the upper surface, that is, the side facing toward the center of the back surface of the fuse socket 1 when in use. A terminal rotation prevention portion 7 is provided.

The angle of the triangular apex of this terminal rotation prevention portion 7 is not particularly limited, but if the two crimp terminals 4, 4 are to be individually defined at an angle of about 45°, it is preferably set to about 90°.

Legs 8, 8 for preventing rotation of the metal fittings themselves are suspended from both ends of the horizontal portion of the upper surface constructed in this manner.

The distance between the legs 8, 8 is such that the legs 8, 8 can be fitted into the left and right sides of the fuse socket 1.

Next, in order to fix the crimp terminal 4 with the wired portion 5 bent at approximately 90 degrees using the metal fitting 6 formed in this way, first the two crimp terminals 4, 4 are attached to the wired portion 5, 5. toward the center of the back of the fuse socket, open each crimp terminal 4, 4 to about 45 degrees, and then open both legs 8, 8 of the detent fitting 6.
into the left and right sides of the fuse socket 1, press the horizontal part of the upper surface of the metal fitting 6 against the horizontal base part of each crimp terminal 4, 4, and press the triangular terminal rotation prevention part 7 into each crimp terminal 4,
Insert it between the open standing attached line parts 5 and 5 of 4.

After that, the metal fitting 6 is fixed with the tightening screw 3.

Then, one triangular side of the terminal rotation prevention portion 7 comes into contact with the base portion of the crimp terminal 4, and rotation of the crimp terminal 4 is prevented.

This prevents the crimp terminal 4 from protruding from the mounting surface on the back side of the fuse socket.

Further, the surroundings of the metal fitting itself are blocked by both legs 8, 8.

Therefore, the length of the legs 8, 8 is at least the length of the crimp terminal 4.
It is necessary that the thickness be at least the thickness of two horizontal root portions of the

Further, fixing of crimp terminals is not limited to the case of two crimp terminals, but can be similarly performed even in the case of one crimp terminal.

As described above, according to the present invention, the crimp terminal rotation preventing portion of the detent fitting is approximately triangular, so when the detent fitting is attached to the fuse socket from above the crimp terminal, the crimp terminal However, since it is installed at an angle of about 45 degrees, it is possible to mount the crimp terminals without contacting each other and without protruding from the mounting space of the fuse socket, which saves mounting space. It is possible to improve efficiency and improve efficiency.

Although the present invention has been described with respect to crimp terminals, it is of course applicable to other connection terminals having similar problems.

Claims (1)

[Scope of utility model registration request] When fixing two connection terminals on the back of a device such as a fuse socket with wired parts bent upwards from the horizontal base, facing each other within the space on the back of the device, the anti-rotation fittings of the terminals are roughly U-shaped. A triangular terminal rotation prevention portion is provided on one side of the horizontal portion of the upper surface of the metal fitting and protrudes in a triangular shape on the side facing toward the center of the back of the device, and one side of the terminal rotation prevention portion is connected to the bent portion of the connecting terminal. Position the connection terminal at a desired angle with respect to the device by touching the base of the metal fitting, and fit the legs hanging from both ends of the horizontal upper surface of the metal fitting to the sides of the device, so that the metal fitting and the connection terminal are horizontal. A rotation-preventing structure for a connection terminal, characterized in that the base portion is fixed to the above device with a tightening screw.
