Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electrical connection terminal that can be easily attached and detached even in a narrow space in the axial direction.

[0002]

2. Description of the Related Art When electric wires or cables are detachably connected to each other by means of electric connection terminals, one end of one electric wire is connected to a male terminal, and the other end of an electric wire is connected to a female terminal. The electric wires are detachably connected to each other.

[0003]

However, in the above-mentioned conventional electrical connection terminal, the space for the connection portion is narrow because the connecting direction between the male terminal and the female terminal is limited to the axial direction of the male terminal. In some cases, it may not be possible to use the connecting terminal having such a structure. In addition, as the cable size increases, the connection terminal also increases in size, which increases the weight and rigidity of the connection terminal, thus requiring a great deal of labor for connection work.

The present invention has been made in view of the above points, and can be easily attached and detached even in a place where the space of the connection terminal in the axial direction is small, and the connection work can be performed even if the cable size is large and the connection terminal is large. It is an object of the present invention to provide an electrical connection terminal that is easy to operate.

[0005]

In order to achieve the above object, according to the present invention, the end of one electric wire is connected to the base end,
A female terminal is formed with a receiving portion that opens in the axial direction and sideways at the tip, and the end of another electric wire is connected to the base end, and a connecting portion is formed at the tip that fits closely to the receiving portion from the side. A male terminal, a spacer that is laterally attached to the receiving portion of the female terminal and holds the connecting portion of the male terminal fitted in the receiving portion, and an axial direction in the female terminal. The configuration is such that it is slidably fitted to the outside and a slider is fitted to the receiving portion that holds the connecting portion of the male terminal and the spacer to connect these to each other.

The male terminal connecting portion is laterally fitted and closely fitted to the female terminal receiving portion, and the spacer is closely attached to the receiving portion of the connecting portion so as to be attached and mounted. The connecting portion is held by the portion and the spacer. Next, the slider mounted on the female terminal is slid in the axial direction to be externally fitted to the receiving portion and the spacer, and the receiving portion, the connecting portion and the spacer are closely attached and fixed. This electrically and mechanically connects the female terminal and the male terminal. By connecting the male terminal to the female terminal from the side, the male terminal can be easily attached and detached even in a place where the space in the axial direction is narrow. Moreover, even if the size of the cable becomes large and the size of the connection terminal becomes large, the attachment / detachment work is easy.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. As shown in FIGS. 1 and 2, the electrical connection terminal 1 includes a female terminal 2, a male terminal 3, a spacer 4, and a slider 5. Female terminal 2
Has a hole 2b into which a terminal of an electric wire to be connected is inserted and connected, and a receiving portion 2c is formed at the tip end. The receiving portion 2c has a cylindrical portion formed by forming a large-diameter hole in the axial direction on the tip end surface thereof,
The cylindrical portion is cut in half along the axial direction and one side is cut off (gutter shape). Thereby, the receiving portion 2c
Has a shape that is open at the tip and sideways. Further, the spacer 4 has the same shape as the half-cut portion cut to form the receiving portion 2c. Therefore, the spacer 4
Can be formed simultaneously with the receiving portion 2c.

The receiving portion 2c and the spacer 4 are formed so as to be slightly shallower (smaller) than the half, and when these are combined into a cylindrical shape, there is a slight gap between the end faces on both sides along the axial direction. Then they are facing each other. As a result, as will be described later, when the connecting portion 3c of the male terminal 3 is connected, good contact and strong connection are possible. Receiver 2c
Has an outer diameter slightly larger than the outer diameter of the base end 2a, and is formed such that the outer peripheral surface slightly expands from the base end 2a side to the tip end side. . Spacer 4
Is formed similarly to the receiving portion 2c. The end surface 2d of the receiving portion 2c on the side of the base end 2a is a tapered surface that slightly extends from the bottom surface side of the receiving portion 2c to the opening end side (from the bottom to the top in the figure). Further, a taper pin hole 2e having a small diameter is formed in the radial direction in the vicinity of the receiving portion 2c side of the base end 2a.

The male terminal 3 has a stepped cylindrical shape, and has a base 3
a has a diameter slightly smaller than the base end 2a of the female terminal 2,
The connecting portion 3c has a diameter slightly smaller than that of the base end 3a, and has an outer diameter capable of being fitted into the receiving portion 2c of the female terminal 2. The length of the connecting portion 3c is set to be the same as the length of the receiving portion 2c. The base end 3a may have a larger diameter or the same diameter as the connecting portion 3c. A hole 3b into which an end of an electric wire to be connected is inserted and connected is formed in the center of the end face of the base end 3a, and the tip end face 3d of the connecting portion 3c is a tapered face corresponding to the end face 2d of the receiving portion 2c. (Fig. 2).

When the spacer 4, the connecting portion 3c of the male terminal 3 and the receiving portion 2c of the female terminal 2 are connected as shown in FIGS. 2 and 3, substantially the center of the connecting portion is diametrically penetrated. Square pin holes 4a, 3f and 2f are formed. These pin holes 4a, 3f, and 2f are tapered holes that gradually decrease from the pin hole 4a of the spacer 4 toward the pin hole 2f of the receiving portion 2c. Furthermore, the holes 4a, 3f, and 2f are connected to the connecting portion 3c.
The surface on the base end side is a straight surface along the diametrical direction, and the surface on the front end surface 3d side is an inclined surface.

The slider 5 has a thick-walled cylindrical shape, the inner diameter of which is slightly smaller than the outer diameter of the tip of the receiving portion 2c of the female terminal 2, and the length of which is slightly smaller than the length of the receiving portion 2c. Is set to long. The slider 5 is fitted onto the base end 2a of the female terminal 2 with a slight gap, and is slidable in the axial direction. The female terminal 2, the male terminal 3, the spacer 4, and the slider 5 are formed of a conductive metal member such as copper or a copper alloy. The slider 5 does not necessarily have to be a member having conductivity, but may be another member such as an insulating member. However, the slider 5 needs to be a member that has high strength and is hard to be deformed and does not particularly expand in diameter. The slider 5 may be formed of copper or a copper alloy and the surface thereof may be subjected to an insulation treatment.

The operation will be described below. First, as shown in FIG. 2, the conductor end 10a of the cable 10 to be connected is placed in the hole 2b of the base end 2a of the female terminal 2, and the conductor end 11a of the cable 11 is placed in the hole of the base end 3a of the male terminal 3. Insert in 3b,
Electrically and mechanically connecting by means such as soldering, brazing, or pressure bonding. Then, the connecting portion 3c of the male terminal 3 is fitted from the side of the receiving portion 2c of the female terminal 2,
Attach the spacer 4. As a result, the connecting portion 3c is held by the receiving portion 2c and the spacer 4. Next, the taper pin 6 is press-fitted into the pin holes 4a, 3f, 2f from the spacer 4 side to fix them. The taper pin 6 is set to be slightly shorter than the outer diameter of the receiving portion 2c of the female terminal 2.
As the taper pin 6 is inserted, the connecting portion 3c of the male terminal 3 is pushed toward the female terminal 2 by the tapered surface, and the tip surface 3d is pressed against the end surface 2d as shown in FIG.

Next, as shown in FIG. 3, the base end 2a of the female terminal 2 is
The slider 5 mounted on the side as shown by the arrow in the receiving portion 2c.
To the connecting portion between the connecting portion 3c and the spacer 4,
While the diameters of c and the spacer 4 are being reduced, the tapered pin hole 2e is pushed to a position where the tapered pin hole 2e is opened and externally fitted. At this time, the tip and the head of the taper pin 6 slightly enter the pin holes 2f and 4a from the surfaces of the receiving portion 2c and the spacer 4, thereby preventing the slider 5 from sliding. The inner surfaces of the receiving portion 2c and the spacer 4 are in pressure contact with the outer peripheral surface of the connecting portion 3c.
Next, the taper pin 7 is press-fitted into the taper pin hole 2e formed in the base end 2a of the female terminal 2 to form the base end 2 of the slider 5.
Prevents return to side a. As a result, the slider 5 is fixed to the connecting portion.

An end surface 3d of the connecting portion 3c of the male terminal 3 is pressed against the end surface 2d of the receiving portion 2c of the female terminal 2, and the receiving portion 2c and the inner surface of the spacer 4 are pressed against the outer peripheral surface to electrically connect. Then, the taper pin 6 fixes the receiving portion 2c so as not to deviate in the axial direction. Thereby, the female terminal 2 and the male terminal 3 are electrically and satisfactorily connected mechanically. The male terminal 3 can be connected from the side of the female terminal 2, so that it can be easily connected even in a place where the space in the axial direction is small. Further, the cable size becomes large, and accordingly, the connection terminal becomes heavy, and even if the rigidity becomes strong, the connection work can be easily performed. When the connection between the female terminal 2 and the male terminal 3 is released, the operation opposite to the above may be performed.

FIG. 4 shows an example in which the connection terminal 1 according to the present invention is applied and the cables 13 and 14 are connected by the relay cable 15 in the relay box 12 in which the space in the axial direction of the cable is particularly narrow. In FIG. 4, cables 13, 1
Each of the terminals 4 of the conductors 4 penetrates the holes 12a and 12b of the relay box 11 and is inserted into the box.
Female terminals 2 and 2 are connected to a and 14a, respectively. on the other hand,
Male terminals 3 and 3 are connected to both ends 15a and 15b of the conductor of the relay cable 15, respectively. This relay cable 1
5 from the side of the female terminals 2 and 2 as shown by the arrow,
The connecting portions 3c and 3c are fitted to the receiving portions 2c and 2c, the spacers 4 and 4 are attached, and the taper pin 6 (not shown) is press-fitted.
The sliders 5 and 5 are externally fitted and fixed to the connecting portion. As a result, the relay box 12 has a small space in the axial direction of the cable.
It becomes possible to easily connect the cables 12 and 13 inside. The male terminals 3 may be connected to both ends of a simple conductor rod instead of the relay cable 15.

In the above embodiment, the slider 5 is simply slid in the axial direction so as to be fitted onto the connecting portion. However, the present invention is not limited to this. For example, the receiving portion 2c of the female terminal 2 can be used. Alternatively, a male screw may be engraved on the outer peripheral surface of the spacer 4 and a female screw may be engraved on the inner surface of the slider 5, and the slider 5 may be axially moved by screw coupling to be externally fitted to the connecting portion.

[0017]

As described above, according to the present invention, the connecting portion of the male terminal is laterally fitted and closely fitted to the receiving portion of the female terminal, and the male terminal is closely attached to the receiving portion of this connecting portion. The spacer is closely attached from the side not attached, and the connecting portion is held by the receiving portion and the spacer. Next, the slider mounted on the female terminal is slid in the axial direction to be externally fitted to the receiving portion and the spacer, and the receiving portion, the connecting portion and the spacer are closely attached and fixed.
This electrically and mechanically connects the female terminal and the male terminal. By connecting the male terminal to the female terminal from the side, the male terminal can be easily attached and detached even in a place where the space in the axial direction is small, and the workability can be greatly improved. Further, even if the size of the cable becomes large and the connection terminal becomes large accordingly, the attachment / detachment work is easy and the labor is reduced.
