Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connecting terminal for fitting with a mating connecting terminal.

[0002]

2. Description of the Related Art As shown in FIG. 4, for example, a conventional insertion connecting terminal 1 is fixed to a connecting end 2 at a front end connected to a mating connecting terminal and a terminal accommodating hole 4 in a connector housing 3. The intermediate portion 5 and the electric wire connecting portion 7 at the rear end portion for connecting the electric wire 6 and the core wire 6a. Further, the intermediate portion 5 is provided with a lance fitting hole 9 into which the flexible lance 8 extended from the connector housing 3 is fitted, and a projecting piece 10 for locking the flexible lance 8.

[0003]

However, in the above-mentioned conventional example, the core wire 6a of the electric wire 6 has the lance fitting hole 9 formed therein.
When the connection terminal 1 is inserted into the terminal accommodating hole 4, the core wire 6 is inserted into the terminal accommodating hole 4 when the connection terminal 1 is crimped to the vicinity of
There is a possibility that the a may collide with the flexible lance 8, the flexible lance 8 may not be sufficiently inserted into the lance insertion hole 9, and the connection terminal 1 may come out.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned problems and to provide a connection terminal in which a flexible lance is securely fitted into a lance fitting hole and is locked to a housing.

[0005]

A connection terminal according to the present invention for achieving the above-mentioned object is a connection terminal which is inserted into a terminal accommodating hole of a connector housing and locked by a flexible lance. Connection end provided at the front end for connecting to the wire, a lance fitting hole provided at the middle part of the bottom for fitting the flexible lance, and a wire connection provided at the rear end for connecting the core wire of the wire. And a stopper for pressing the tip of the core wire at a predetermined position between the lance insertion hole and the electric wire connecting portion.

[0006]

In the connection terminal having the above structure, the flexible lance is obstructed by the core wire because the stopper is provided between the lance fitting hole and the electric wire connecting portion to prevent the core wire from entering the vicinity of the lance fitting hole. Without being inserted into the lance insertion hole.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail with reference to the embodiments shown in FIGS. FIG. 1 is a perspective view of the embodiment, and FIG. 2 is a side view showing a part of it in section. For example, the connection terminal 11 for insertion is formed by punching and bending one conductive metal plate, and the front end portion has a connection end 12 to be inserted into the receiving connection terminal on the other side and an intermediate portion fixed to the connector housing. 13 and an electric wire connecting portion 15 that connects the electric wire 14 and its core wire 14a to the rear end portion. Middle part 13
The bottom plate 13 a of the connector has a lance fitting hole 16 into which the flexible lance of the connector housing is fitted, a locking piece 17 provided on the opposite side of the lance fitting hole 16 for locking the flexible lance, and an electric wire of the lance fitting hole 16. Provided on the side of the connecting portion 15 are a stopper 18 for restricting the tip position of the core wire 14a, and a stabilizer 19 standing up from both side surfaces. Further, the wire connecting portion 15 is formed with a core wire crimping portion 21 for crimping the core wire 14a and a covering crimping portion 22 for crimping the covering 14b of the electric wire 14.

The connection end 12 is formed into a flat blade by folding back the bottom plate 12a and the top plate 12b so as to be in close contact with each other.
In front of the intermediate portion 13, both side plates 13b bent from the bottom plate 13a are further bent and abutted to form a rectangular tube shape, and the bottom plate 13a is cut open to form a lance fitting hole 16, and the remaining portion is By being bent inward, a projecting piece-like locking piece 17 and a stopper 18 are formed. The stabilizer 19 is protruded upward without the side plates 13b being bent, and the rear of these is bent inwardly above the stopper 18 so as to face the inside. The core wire crimping portion 21 and the cover crimping portion 22 are formed by bending the side plates 15b from the bottom plate 15a into a U shape.

FIG. 3 is an explanatory view when the connection terminal 11 is housed in the connector housing 23, and the upper portion is the connection terminal 1.
1 shows the state of being inserted inside out, and the lower part shows the state of being inserted correctly. The connector housing 23 has a plurality of terminal accommodating holes 24 for accommodating the connection terminals 11.
Are arranged side by side, for example, in two stages, and a flexible lance 25 for locking the connection terminal 11 is provided in front of the terminal receiving hole 24 with a partition wall 26.
Is projected diagonally forward from. The flexible lance 25 is provided with a pressing portion 27 that presses the bottom plate 13a of the intermediate portion 13 of the connection terminal 11, and a locking portion 28 that locks the locking piece 17.
The pressing portion 27 prevents the connection terminal 11 from moving up and down, and the locking portion 28 prevents the connection terminal 11 from coming out backward. A locking step portion 29 is provided on the side of the terminal accommodating hole 24 opposite to the flexible lance 25 and abuts on the stabilizer 19 to prevent the connection terminal 11 from slipping forward.

When using such a connecting terminal 11, both side plates 15b are bent inward so that the tip of the core wire 14a contacts the stopper 18, and the core wire 14a and the covering 14b are crimped. As a result, the wire 14a is securely fixed to the connection terminal 11 without the core wire 14a penetrating into the lance fitting hole 16.

When such a connecting terminal 11 is correctly inserted into the terminal accommodating hole 24, the bottom plates 12a, 1 of the connecting terminal 11 are
3a moves forward while pushing up the flexible lance 25, the stabilizer 19 collides with the locking step 29, and the forward movement of the connection terminal 11 is stopped. At the same time, the flexible lance 25 is restored so that the locking portion 28 is fitted into the lance fitting hole 16 and the pressing portion 2
7 is elastically contacted with the pressed portion 16, and the locking portion 28 is engaged with the locking piece 17. As a result, the intermediate portion 13 is prevented from moving in the vertical direction by the pressing portion 27 and the locking step portion 29, and is prevented from moving in the front-back direction by the locking portion 28 and the locking step portion 29. The side plates 13b elastically contact the side walls of the terminal receiving hole 24, so that the left and right movements are prevented.

When the connection terminal 11 is inserted into the terminal accommodating hole 24 with the top and bottom turned upside down, the stabilizer 19 of the connection terminal 11 causes the base portion 3 of the flexible lance 25 to move.
0, the connection terminal 11 cannot move any further. This prevents the connection terminal 11 from being housed in the terminal housing hole 24 in the wrong posture.

[0013]

As described above, in the connection terminal according to the present invention, the core wire is provided with the stopper for preventing the core wire from entering the vicinity of the lance fitting hole between the lance fitting hole and the wire connecting portion. Can be securely locked to the housing without disturbing the locking by the flexible lance.
