Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to an electrical connection device, and more particularly, it is used for electrically connecting circuits or devices.

(Prior art) Electrical connection between a terminal of an electronic circuit and a conducting wire portion of a lead wire,
Alternatively, electrical connection devices called connectors, terminal blocks, or the like are conventionally known as devices for electrically connecting conductor portions of lead wires. As such an electrical connection device, for example, Japanese
M, No. 56-46231 is required. Both of these have two connecting conductive plates facing each other, and a conductive wire portion of a lead wire or a plate-shaped terminal is inserted between them. Then, the conducting wire portion or the terminal is pressed and held between two connecting conductive plates.

[Problems to be Solved by the Invention] However, in the conventional device as described above, the connecting conductive plate and the conductor portion or terminal of the lead wire are electrically connected by contacting each other at only one point. Therefore, there is a drawback that the contact resistance value becomes unstable or becomes high. Further, metal-to-metal contact between the connecting conductive plate for electrical connection and the conducting wire portion or terminal of the lead wire prevents the lead wire or the terminal from coming off from the electrical connection device. For this reason, when a force is applied between the two to separate them from each other, the lead wire or terminal easily comes off from the electrical connection device, resulting in a loss of electrical connection.

The present invention has been made with these points in mind, and it is an object of the present invention to provide an electrical connection device that has good electrical connectivity and can strongly hold the connected terminal or terminal. purpose.

An electrical connection device according to the present invention includes a base body having an elongated substrate portion, a plurality of partition plate portions formed to protrude upwardly at predetermined intervals in the longitudinal direction of the substrate portion, and a base body having a predetermined length in a plane. a first connecting conductive plate having a first contact conductive plate portion formed in the plane and having an opening formed in this plane, and fixed to a substrate portion sandwiched between partition plate portions of the base body; and a partition of the vehicle body. an insertion member that is formed between the plate parts so as to be inserted from above and has a protrusion that is inserted into the opening of the first contact conductive plate part when inserted;
It has a second contact conductive plate portion formed in a plane with a required length and an opening formed in this plane, and the protruding portion of the insertion member is slidably inserted into the opening of the second contact conductive plate portion. , and a second contact member that is attached to the insertion member so as to be able to move up and down, and a spring that is provided between the insertion member and the second connection conductor plate and elastically presses the second connection conductor plate downward. and fixing means for fixing the insert member to the base body when the insert member is inserted.

(Function) Since the electrical connection device according to the present invention is configured as described above, the first and second contact conductive plate portions move so as to maintain electrical contact with the terminals sandwiched between them, and the insertion The protruding portion of the member cooperates with the first and second contact conductive plate portions to securely hold the terminal.

is formed.

An insert member 4 is inserted between two adjacent partition plates 2, and a second connecting conductive plate 5 is attached to the insert member 4 so as to be movable in the vertical direction. . Second
The connecting conductive plate 5 has a central portion formed into a plane with a required length to form a second contact conductive plate portion 51, and conductive plate portions on both sides of the connecting conductive plate 5 are slidably inserted into slits formed in the insertion portion vi4. It will be done. Both ends of the second connecting conductive plate 5 are bent to form a bent portion 52, and this bent portion 52 can be moved up and down within the cavity 41 formed in the insertion member 4. . Further, an opening is formed in the center of the second contact conductive plate portion 51, and the protruding portion 13 of the insert member 4 is slidably passed through this opening. A coil spring 8 for elastically pressing the second connection conductor plate downward is provided between the second contact conductor plate portion 51 and the inner surface of the insert member 4 .

Further, the partition plate portion 2 is formed with a notch 61 having a concave cross section, and the insert member 4 is also formed with notches 62 and 63 at corresponding positions. A recess 64 is formed on the side surface of the insert member 4 between the notches 62 and 63.

The insertion member 4 is fixed by inserting the fixing member 7 shown in FIG. 3 into the notches 61, 62, 63 and the recess 64. That is, the protrusion 71 is inserted into the recess formed by the notches 61 and 62, the protrusion 72 is inserted into the recess 64, and the protrusion 73 is inserted into the notch 63 and the notch of the partition plate (not shown). Insert it into the recess formed by.

Next, the operation of the apparatus of the above embodiment will be explained. Electrical connection to this electrical connection device is made, for example, by a terminal 9 shown in FIG. An opening 91 is formed in this terminal 9, and the protrusion 43 of the insertion member 4 can be inserted into this opening 91. Further, a lead wire 92 is held at the base of the terminal 9.

Figure 5 is a sectional view for explaining the connection operation;
> indicates a connected state, and (b-) in the same figure shows the state after the connecting curve, connection, or disconnection is released. Same figure (
As shown in a>, since the terminal 9 is held by inserting the protrusion 43 into the opening 91, the terminal 9 will not come off even if a handling force is applied to the terminal 9, for example. Also,
Since the terminal 9 is sandwiched between the first and second contact guide portions 31.51 formed in a flat plane with a required length, good electrical contact can be obtained.

The connection operation is performed as follows. First, as shown in FIG. 5(b), remove the fixing member 7 and pull the insert member 4 upward.
Insert terminal 9 between them. Then, the opening 91 of the terminal 9, the protrusion 43, and the openings of the first and second connection plates 3 and 5 are aligned in a straight line.
