Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a connector for connecting a current path, and particularly to a connector for connecting a current path in a remote and narrow space.

Conventionally, there has been a device of this type as shown in FIG.

As shown in the figure, the connector +I+ has a movable contact such as a male pin (2), an insulating mounting body (3) that fixes a male pin (21), a fixed contact such as a female pin +41, a female pin (
4) is made up of a guide pipe (51) that fixes it.

+61 and (71 are lead wires connected to the male pin (3) and female pin (4), respectively. The female pin (4) is attached with a fixing screw (8) so as to block the inside of the guide pipe (5).

To form a current path connected to lead wires +61 and +71, insert the entire mounting body (3) into the guide pipe (5), move it to the position where the female pin (41) is attached, and pull it to the male pin. into the female pin (4).The male pins (3) and female pins (4) are equal in number and have a one-to-one correspondence, so parallel current paths equal to the number of contacts are electrically connected. It turns out.

Since the conventional connector (11) is configured as described above, if the contact point is deep inside the guide pipe (51), the positions of the male pin (3) and female pin (4) may shift slightly, and all male pins (31 becomes extremely difficult to fit into the female pin (4). Also, in order to minimize heat intrusion from the outside, the smaller the diameter of the guide pipe (5), the better. However, the current When you want to increase the electrical capacity of the circuit, use male pin (3) and female pin (3).
In order to widen the contact area (4), it is necessary to increase the diameter of the pin or make the pin longer, but if the pin is made thicker,
If the diameter of the guide pipe (5) becomes thicker and the pin becomes longer, the mechanical strength of the pin decreases and it becomes easier to bend. Therefore, with conventional connectors, it is difficult to significantly increase the electrical capacity of the current path.

This invention was made in order to eliminate the drawbacks of the conventional ones as described above, and it includes a connector that is attached to a guide pipe, a fixed contact that is attached to the side of the guide pipe, and that is movable in the axial direction of the guide pipe. and a movable contact attached to the mounting body that can contact the fixed contact, thereby easily and reliably connecting a current path at a remote location. The purpose of the present invention is to provide a connector that can increase electric capacity with low heat penetration without increasing the diameter of the guide pipe.

An embodiment of the present invention will be described below with reference to the drawings. Second
In the figure, aυ is a movable contact, e.g. a contact spring plate, α
2 is a mounting body that fixes the contact spring plate (lυ), and this mounting body (
121 is formed of, for example, a fixed base (13) and a mounting pipe α fixed perpendicularly to the fixed base (13). 051
is a lead wire connected to the contact spring plate (11), α is a fixed contact such as a contact pin, aη is a guide pipe that fixes the contact pin Oe, (I81 is a lead wire connected to the contact pin θ0).

To form a current path connected to the leads <+s, <te, insert the entire mounting body into the guide pipe α force,
For example, a contact spring plate (11) made of a conductive elastic body is pressed against the contact pin 06). Since the numbers of contact spring plates (11) and contact pins α6) are equal and have a one-to-one correspondence, parallel current paths corresponding to the number of contacts are electrically connected. Compared to conventional insertion, this invention only requires pressing, making contact much easier. In addition, when it is desired to increase the electric capacity, the surface area of the contact portion of the contact spring plate αυ and the contact pin (16) is extended in the axial direction of the guide pipe (1η
This is easily possible without increasing the diameter of the guide pipe. In this case, the only limitation on the capacitance is the length of the guide pipe.

In the above embodiment, the contact spring plate (11) was attached to the outside of the fixed base 03), but as shown in FIG. Even when the contact spring plate (11) is attached to the inside of the fixing base (13) and the contact pin Q6) is attached to the outside of the guide pipe (17) with such a configuration, the same effect as in the above embodiment can be obtained. be.

In addition, as another embodiment, the guide pipe is configured in a double manner with a first guide pipe and a second guide pipe, and contact pins are attached to the inner surface of the first guide pipe and the outer surface of the second guide pipe, In other words, further outside the connector shown in Figure 3,
A first guide pipe is provided, and a first contact pin is attached to the inner surface of the guide pipe at the same position as the contact pin (I6). In addition, a first contact spring plate is attached to the outside position opposite to the contact spring plate αυ attached to the inside of the fixed base α3). With this configuration, when connecting the connector, the current path between the outside of the fixing base (2) and the contact pin on the first guide pipe, and the inside of the fixing base (2) and the contact pin on the second guide pipe I can do it. In addition to the effects of the above embodiments, this embodiment has the advantage that the number of contact conductors can be increased without increasing the diameter of the guide pipe or changing the width of the contact spring plate.

Still another embodiment is shown in FIG. In this example, the fixed base Q
31 is a conical stand, contact spring plate IJA) and contact bottle a
The contact surface when O is in contact with the mounting body Q is configured to have a certain angle with respect to the moving direction of the hot water. With this configuration, in addition to the effects of the first embodiment, the fixed base cannot move further into the guide pipe (t7) than in the contact state, so that the guide pipe (17) There is also a positioning effect on the depth.

In addition, by making the guide pipe (I7) a polygon with no axis of line symmetry, the rotation of the guide pipe (Iη) and the fixed base (13) can be adjusted so that the guide pipe (I7) and the fixed base 03 can be It is possible to perform positioning for the rotation of the

In addition, in the above embodiment, the mounting pipe round and the guide pipe (t
7) are both coaxial straight pipes, but both do not have to be coaxial, and furthermore, both do not have to be straight pipes.

As another embodiment, FIG. 5 shows an example in which the mounting pipe circle and the guide pipe α force are both curved pipes. α is a lead wire. Since the surface of the attachment pipe αa is pleated and has an arbitrary curvature along the guide pipe 07), it becomes possible to bend the guide pipe (17) freely.

In this embodiment, for example, if there is an obstacle, the guide pipe (17
) can be easily attached to and detached from a connector located in a position where the connector cannot be moved straight.

Further, in the above embodiment, a conductive elastic body is used as the movable contact 01), but a conductive elastic body may be used as the contact of the fixed contact (16). A conductive elastic body may be used for both the contact (11) and the fixed contact (1G). An example of the conductive elastic material is beryllium bronze, but other materials may be used as long as they are conductive. Alternatively, a conductive coating on an insulator may be used.

Furthermore, in the above embodiment, the movable side lead wires α are passed through the mounting pipe α, but the surface or the entire mounting pipe o4) should be made of an insulator. Alternatively, after the surface is insulated and coated, a conductive plate, for example a copper plate, may be attached on the mounting pipe (15) as a current path. Furthermore, the guide pipe surface needs to be an insulator, but the fixed contact (16) may be attached using a part of the metal pipe as an insulator, or the guide pipe (17) may be made entirely of metal and the fixed contact α6 ) and the guide pipe α force may contact each other on the surface thereof.

Furthermore, the movable contact αυ and the fixed contact (15) of the present invention are attached to the outer surface of the mounting body (3) of the conventional connector (1) and the inner surface of the guide pipe (5) of the conventional connector i11.
By attaching these, it is possible to increase the number of contact conductors and increase the electric capacity using the guide pipe (5) having the same diameter as the conventional one.

As mentioned above, this invention allows for the connection of a connector at a remote location that cannot be visually confirmed, and also prevents the diameter of the connector from being large in order to prevent heat from entering from the outside. Used in narrow spaces. In such a case, for example in FIG. 2, when the movable contact (II) is inserted into the guide pipe (17), there is a possibility that it will pass past the position of the fixed contact (16). Also, the moving contact α is not required.
It cannot be said that there is a possibility that contact between υ and the fixed contact θ6) may occur. Completely eliminates such contact malfunctions,
An embodiment for making the connector even more reliable is shown in FIGS. 6 and 7. In the figure, the plate is a positioning plate attached to the mounting body (1) at a certain depth from the movable contact side of the mounting body (1). This corresponds to the depth from the mouth to the fixed contact (16).As shown in Figure 6, the positioning plate (2
0) and the upper surface of the guide pipe (17) are provided with scales (2I) for determining the rotational position of the mounting body Q21. In this embodiment, by attaching the positioning plate (2α), the connection position of the connector within the guide pipe (I7) can be determined from a remote part.

Further, FIGS. 8 and 9 show other embodiments having a positioning function. In the figure, a convex part, such as a guide pin (22), provided on the fixed base (l) of the numeral body α2 slides in a concave part, such as a guide groove (23), provided on the guide pipe (I7). , prevents unstable rotation of the mounting body α2). In addition, by appropriately determining the depth of the guide groove (23), the guide pipe (
The insertion depth into lη can be determined.

In this embodiment, the same effect can be obtained even if the guide pin (22) is provided on the outer periphery of the mounting pipe (2) with no mounting body.

As described above, according to the present invention, the connector includes a guide pipe and a fixing liquid attached to the side of the guide pipe.
A current path at a remote location can be controlled by providing a feeler, a mounting body movable in the axial direction of the guide pipe, and a movable contact mounted on the mounting body and capable of contacting the fixed contact. It is possible to obtain a connector that allows easy and reliable connection and allows for increasing electrical capacity without increasing the diameter of the guide pipe or increasing heat penetration.
