Description

[Detailed Description of the Invention] [Technical Field of the Invention] 1- is related to a locking terminal device, and includes a terminal piece and this terminal piece K.
The present invention relates to a configuration in which a ridge spring piece that presses t# and bites into and locks 11- is housed and held in the container body.

[Technical background of the invention]

In the conventional type locking terminal device, a terminal piece and a plate spring piece having a locking piece portion facing the terminal piece are stored in a terminal housing portion of a container body, and are pushed through the 1IE-insertion hole of the container body. Connect the terminal piece to the chain part of the leaf spring piece [while pressing #t-
A structure is adopted in which the IE is bitten and locked, and the IE is prevented from being removed and retained.

[Intermediate point of support a supplement]

In conventional terminal devices, the terminal piece and the leaf spring piece are stored facing each other in the terminal storage part of the device without partitioning them, so the leaf spring piece is first inserted, and then when the terminal piece is inserted, the spring piece is If the terminal piece is moved to the space where the terminal piece is inserted, and the terminal piece is not easily inserted, the terminal piece cannot be inserted if the body is tilted, and the connected electric wire will move along one direction of the terminal piece. The cross-sectional area of the wire becomes smaller due to damage from electrical melting, which increases heat generation, and it becomes difficult to release the wire. The pressure contact force of the chain-piece part is the I111 of the terminal piece and the terminal housing part of the container body.
This has the disadvantage that the pressing force is divided into 1 rM portions, and the pressing force against the electrical terminal piece is reduced.

[Purpose of the invention]

The present invention was made in view of the above-mentioned drawbacks, and the terminal piece and the ridge spring piece are housed separately in the container body, the ridge spring piece is held in pressure contact with the container body, and even if the container body is tilted, the terminal piece and the ridge spring piece are housed separately. It is possible to insert the terminal piece without the piece being loose, and the terminal piece can be pushed in easily.
To provide a locking terminal device with which the connection is reliable and there is no risk of heat generation due to the connection of electric wires.

[Overview of Fukban]

The structure of this @dog is an insulating unit with @-God communication holes formed,
A terminal piece housed in this container body, and an llIII lock piece portion that presses the terminal piece housed in the body and holds the electric wire, which is housed in the body opposite to the terminal piece and is pushed through the wire insertion hole, into the starting terminal piece and locks the electric wire. - The terminal piece of the arrangement body and the leaf spring piece are provided with a paper on both sides held in the v1 and 11 sides. Ribs with a thickness thinner than the smallest diameter electric conductor to be connected are protruded from each other, and one side of the ribs is used as an insertion guide surface for the terminal piece, and the other side is used as a locking piece part of the leaf spring piece. Insert two electric wires inserted through the electric insertion hole of the distribution body into the rib seal, and press the electric wires to the terminal piece with the east piece of the 1#L spring piece. It is designed to be locked.

[Invention dormitory example]

Next, the configuration of an embodiment of the present invention will be explained with reference to the drawings.

(1) is an insulating body, and a pair of terminal storage portions (2) are formed adjacent to this integral body (1).
) is open at the top. A 141Kt# insertion hole (3) is formed at one end of the bottom of this terminal storage portion (2). In addition, it is located at #Il of this electric insertion hole (3), and from the inside of this terminal storage part (2) 141 (4) to the electric wire insertion hole (
Ribs t5) t5+ are integrally protruded to face each other up to the vicinity of 3). The inner thickness of this rib +5) 15) is formed to be thinner than the diameter of the minimum diameter of the connectable conductor m(6). And a rib 1511 facing the narrow space of the terminal storage part (2) partitioned and divided by the rib (5) 15)
One side of 51 is used as a terminal piece insertion guide surface (7), and the other side is used as a leaf spring piece @II (If (8)).

Next, (9) is a terminal piece, and both sides of this terminal piece (9) have terminal storage s (both III rM (41 (4) K
Guided tL4 and 4KIJ +6) 151 One terminal piece insertion guide m [7) It is inserted from the upper surface i-ro part along K. The upper end of this terminal piece (9) is formed with a holding piece bent into a substantially inverted U-shape, and this holding piece part holds the terminal piece (9 ) are retained.

Next, KQ- is a double spring piece, which is bent into a substantially U-shape, and the lower side of this double spring piece is bent upwards to form a lock piece (I).
IK is formed, and the upper side is formed into a holding piece part +141 which is curved in a substantially U-shape. Then, this plate spring piece 00 is guided by both sides (41141) of the terminal storage part (2) and stored in the terminal storage part (2), and the lock piece part 0 and the holding piece part I are connected to the ribs. t5) It is designed to come into contact with the spring contact surface (8) of t5J.

Note that the portion of the holding piece QIf formed on the terminal piece (9) along the end mut+outside 111 of the body (1) serves as a wire connection portion 0e.

Next, the operation of this embodiment will be explained.

tt - If you insert it overflowing into the other end EIQ7),
111 edge is guided by both 1111 t41 (4) K,
Chain - One part Qal and restraint - HsI are the leaf springs of the rib (May 5)! A white border is maintained on the 11th side (8).

・ Also, the terminal piece (9) has both edges on the inside @ side (41 (41 is the guide and υbutt5). 15+ terminal piece insertion guide surface (7)
It is stored in the terminal storage 5 (21) as a guide, and the holding piece Q (

Then, the upper surface of the vessel (1) is closed with a lid plate (not shown),
Hold the terminal piece (9) and leaf spring piece 0 so that they do not come out.

In this state, when inserting the electric wire (6) into the insertion hole (3), the rib 15)
151 Insert along K, locking piece l around spring piece 11
The electric wire (6) is inserted while holding the holding piece U in the closed position against the elastic force, and the electric wire (6) is locked by biting into the locking piece UJ. The terminal piece (9) is pressed into contact with the terminal piece (9).

Then, the electric wire (67 is rib t5) 151 K is guided and inserted, so there is little movement after the electric wire (6) is inserted, and the electric wire (6) is connected to the terminal piece (9 (and the locking piece of the leaf spring piece α). Since it is connected to the center part of part 0 and holding piece part I, the electric wire (6j) is brought into contact with the terminal piece (9) with sufficient pressure contact force, and the electric fil!6
) will not be damaged by the locking piece sal.

〔Effect of the invention〕

According to the first QfnK, the diameter of the electric wire to be connected is located in one of the electric insertion holes formed in the body on both sides that guide and hold both sides of the terminal piece and the spring piece of the body. By installing a thinner rib on the opposite side, one side of the rib is used as the insertion guide for the terminal piece, and also as the abutting surface for the locking piece of the other leaf spring piece. Since the leaf spring piece is stored in contact with the rib of the container body, it is held by the elasticity of the locking piece, so there is no electrical charge, and the container body is tilted. You can fit a size 1IIK into the closet without having to fit it! [Because it is inserted along between #1 squares 1, it is easy to insert the wire, the wire does not move, the wire will not be damaged, the # area of the wire will not become small, and the wire will not be damaged.
There is no increase in heat, and there is little biting of the locking piece against the electric wire, making it easy to release. Therefore, the pressing force exerted by the lock piece on the electric terminal piece is large, and the electric wire can be connected reliably.
