Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for press-connecting an electric wire to two rows of terminals of a connector, and more particularly to a connector press-connecting device configured to cut and press the electric wire in one step.

[0002]

2. Description of the Related Art Conventionally, as described in Japanese Patent Laid-Open No. 49-101886, a stuffer member that is driven to move toward and away from a connector having terminals arranged in two rows is provided. There is known a connector crimping device configured to perform the cutting of the electric wire and the crimping of the electric wire to the terminal in one step by the stuffer member.

[0003]

However, in this crimping device, in order to cut one electric wire which is crimped to the terminals of two rows at two positions between the rows of terminals, a piece of electric wire is cut between the rows of terminals. There is a problem that will remain. There is a risk that the broken end of the electric wire may enter the connector and short-circuit between the terminals of the connector. Therefore, it is troublesome that the broken end of the electric wire must be completely removed after the pressure contact of the electric wire.

Further, in this pressure welding device, since the cutting blade for cutting the electric wire is formed integrally with the stuffer member, when the worn cutting blade is replaced, the entire stuffer member must be replaced. Therefore, there is also a problem that replacement of the cutting blade is expensive.

The present invention has been made in view of the above circumstances, and an object thereof is to perform the cutting of an electric wire and the pressure contact with a terminal in one step without causing a broken end of the electric wire, and easily replace the cutting blade. Another object of the present invention is to provide a connector crimping device that can be performed at low cost.

[0006]

To achieve the above object, a connector crimping device according to the present invention is a stuffer member that is driven so as to move toward and away from a connector having a plurality of terminals arranged in two rows. The stuffer member is provided with an electric wire arranged on the connector so as to cross the two rows of terminals so that when the stuffer member approaches the connector, the wires of one row are connected to the terminals of the other row. 2 to press each
The pressure contact portion of the row and the row of the pressure contact portion are displaceably attached to the pressure contact portion along the moving direction of the stuffer member, and when the stuffer member approaches the connector, the electric wire cooperates with the connector to connect the electric wire to the terminal. It is characterized in that a cutting means for cutting into two between the rows is provided.

Another connector pressure welding device of the present invention is
A stuffer member that is driven to move toward and away from a connector having a plurality of terminals arranged in two rows, and an electric wire arranging member that is arranged on the connector and arranges electric wires so as to cross the terminals in two rows. The stuffer member is provided with two rows of pressure contact portions that respectively press-connect the electric wires arranged by the electric wire arranging member to the terminals of one row and the terminals of the other row when the stuffer member approaches the connector. And between the rows of the pressure contact portions so as to be displaceable with respect to the pressure contact portions along the moving direction of the stuffer member, and when the stuffer member approaches the connector, cooperates with the wire arrangement member to move the wires between the rows of terminals. In 2
And a cutting means for cutting into two pieces.

The cutting means includes, in addition to the cutting blade, a member such as a pedestal of the cutting blade which cuts the electric wire in cooperation with the cutting blade.

[0009]

In the connector crimping device of the present invention, when the stuffer member approaches the connector, the crimping portion presses the electric wires to the two rows of terminals, and the cutting means functions as the connector or the electric wire arranging member. Since the electric wires are cooperatively cut between the rows of terminals, it is possible to perform the cutting and crimping of the electric wires in one step.

Moreover, in the connector pressure welding device of the present invention,
Since the electric wire that is pressed into contact with the two rows of terminals is configured to be cut into two between the rows of terminals, no wire ends are generated, and therefore, a troublesome work of removing the wire ends is also unnecessary.

Further, since the cutting means is constructed separately from the stuffer member, the cutting means can be replaced easily and at low cost.

In the connector pressure contact device of the present invention, the cutting means is displaceably attached to the pressure contact portion so that the relative positions of the cutting means and the pressure contact portion can be changed. Therefore, it is possible to flexibly deal with the change of the size of the connector.

The operation of the press contact device of this embodiment will be described below with reference to FIGS. 7 to 12. 7 to 9 are perspective views schematically showing the operation of the main part of the pressure welding device, and FIGS.
FIG. 6 is a cross-sectional view schematically showing the operation of the main part of the pressure welding device.

First, as shown in FIG. 7, the wire arranging member 18 is opened on both sides, and the connector 30 is mounted on the mounting table 17 (see FIG. 1). After mounting the connector 30, the electric wire arranging member 18 is closed, and the electric wires 1 are installed in the respective groove portions 18a of the electric wire arranging member 18 as shown in FIG.

After the electric wire 1 is installed, the operation lever 13 shown in FIG. 1 is rotated in the direction C in the drawing to lower the stuffer member 20 toward the connector 30. As shown in FIG. 11, in the process of descending, the stuffer member 20 first causes the blade portion 23a of the cutting blade 23 to cooperate with the partition wall 36 of the housing 32 to connect the electric wire 1 to two rows of terminals.

Is configured to function as a cradle for cutting the electric wire 1 in cooperation with the cutting blade 23 of the stuffer member 22.

The operation of the pressure welding device of this embodiment will be described below. After mounting the connector 30 on the mounting table 17, the wire placement member
18A is rotated to be placed on the connector 30, and each of the cavities 37 is formed in the groove portion 18a of the electric wire placement member 18A and between the relatively short partition walls 35 formed on the upper surface of the housing 31 of the connector 30. The electric wires 1 are arranged and arranged.

After arranging the electric wire 1, the stuffer member 20 is lowered. In the process of descending, the stuffer member 20 first has the blade portion 23a of the cutting blade 23 as shown in FIG.
The electric wire 1 is cut into two in cooperation with the partition wall 18b of A.
Even after the cutting, the suffuffer member 20 descends, and as shown in FIG. 25, the pressure contact portion 22 presses the cut electric wire 1 and the terminals in two rows.
The connection portions 33c of 33 are pressed against each other. During this time, the cutting blade 23 after cutting the electric wire 1 is the partition wall of the electric wire arranging member 18A.
While being pressed by 18b, the coil springs 24 are compressed, and the coil springs 24 are moved between the two rows of the pressure contact portions 22 with respect to each other. Note that, in the portion where the terminals 33 are arranged in only one row, the electric wire 1 is not cut, but only the pressure contact is performed, which is the same as the above-described embodiment.

After the pressure contact is completed, the stuffer member 20 is raised. When the stuffer member 20 rises, the cutting blade 23 is biased by the coil spring 24 and returns to the reference position as in the above embodiment.

A modification of this embodiment will be described below. Figure 26
FIG. 8 is a diagram showing a modified example of the present embodiment. In the illustrated modification, a blade portion 18d is formed on the top of a partition wall 18b of the electric wire arranging member 18B, which replaces the electric wire arranging member 18A, and is replaced by the cutting blade 23 of the stuffer member 20A, which replaces the stuffer member 20.

It is attached to the stuffer member 20A via a coil spring 24, and is configured to be vertically movable between two rows of pressure contact portions 22 with respect to the pressure contact portions 22, and cooperates with the wire arrangement member 18B. The electric wire 1 is cut.

FIG. 27 is a diagram showing another modification. In the illustrated modification, an electric wire arranging member 18B 'is provided instead of the electric wire arranging member 18B shown in FIG. This wire placement member
In 18B ', the blade portion 18d at the top of the partition wall 18b is formed separately from the partition wall 18b and is attachable to and detachable from the partition wall 18b. The blade portion 18d is attached to the partition wall 18b by a double-sided tape or the like, and is configured to be replaced with a new one when worn.

FIG. 28 is a diagram showing another modification. In this modification, the stuffer member 20 is replaced with the stuffer member 20.
An electric wire arranging member 18C is provided instead of the electric wire arranging member 18A. The stuffer member 20B has a cutting blade 23A that replaces the cutting blade 23, and a blade portion 23a 'that functions as an upper blade is formed at the lower end of the cutting blade 23A. On the other hand, the electric wire arranging member 18C has a partition wall 18b having a blade portion 18d 'functioning as a lower blade formed on the top thereof.

When the stuffer member 20B descends, the cutting blade 23A is held by the blade portion 23a 'until the blade portion 23a' comes into contact with the partition wall 36 on the upper surface of the housing 32 of the connector 30. Wire placement member 18 while sliding contact with 18d '
Entering into the groove 18a of C, the partition wall of the wire arranging member 18C
The electric wire 1 placed on 18b is cut into two pieces. The blade portion 23a 'of the cutting blade 23A may be formed so as to extend parallel to the direction perpendicular to the paper surface, and may be configured to cut a plurality of electric wires 1 at the same time. It may be formed so as to extend obliquely, and the plurality of electric wires 1 may be sequentially cut one by one. If the plurality of electric wires 1 are configured to be cut one by one, the force required for cutting the electric wires 1 can be small, and therefore the device does not need to be robustly configured, so the device can be downsized. It is also possible.

FIG. 29 shows a modification in which the electric wire 1 is pressure-contacted with the above-mentioned connector 30A of another type. In this modification, an electric wire arranging member 18D is provided instead of the electric wire arranging member 18A. This electric wire arranging member 18D does not have a function of aligning a plurality of electric wires 1, and is simply a stuffer member 20.
The difference is that an arm portion 18e that serves as a cradle for the cutting blade 23 is provided. The arm portion 18e is arranged in a recess 34a formed in the partition wall 34 on the upper surface of the housing 32 of the connector 30A, and cooperates with the cutting blade 23 of the stuffer member 20 to move the electric wire 1 placed on the arm portion 18e. It is configured to cut in two.

FIG. 30 shows a modification of the cutting blade 23 of the stuffer member 22. The cutting blade 23B of this modified example has a blade portion 23a.
On both left and right sides, contact portions 23e that come into contact with a member (a housing of the connector or an electric wire arranging member) that functions as a receiving base for the blade portion 23a are provided. With such a configuration, it is possible to suppress the wear of the blade portion 23a and prevent the member serving as the cradle from being scratched.

FIG. 31 shows the abutting portion 23e on the cutting blade 23 as described above.
Instead of providing the above, an example is shown in which a concave portion 40 that receives the tip of the blade portion 23a is formed on the side of the member that serves as the receiving base. With such a configuration, it is possible to suppress wear of the blade portion 23a of the cutting blade 23. It should be noted that FIG. 10A shows an example in which a portion of the recess 40 that abuts the blade portion 23a is formed at a right angle, and FIG. 9B shows an example in which a taper 41 is provided in the same portion. When the member that serves as a cradle is a relatively soft member such as plastic, it is preferable to have a configuration as shown in FIG.

By the way, in each of the embodiments described above, 2
When the cut electric wire is pushed into the cavity of the connector housing by the pressure contact portion of the stuffer member, the cut surface of the electric wire may be deformed by sliding contact with the partition wall of the connector housing or the partition wall of the electric wire arranging member. There is. The occurrence of such deformation of the cut surface is not preferable because it also lowers the connection reliability between the terminal and the electric wire.

A preferred embodiment capable of preventing such deformation of the cut surface of the wire will be described below. FIG. 32 is a diagram showing an example of a mode in which the deformation of the electric wire cut surface can be prevented.

In this example, a pair of clamps 50 for gripping both ends of the electric wire 1 to be cut are provided. The pair of clamps 50 connects the both ends of the electric wire 1 to be cut to the connecting portion 33 of the terminal 33.
It is configured to continue to hold at a position higher than the position where c is located, and the electric wire 1 cut in two is bent by the stuffer member as shown when being pressed into the terminal 33. By bending each cut electric wire 1, the cut surface is pulled toward the clamp 50 side
Since it is separated from the partition wall 36, the cut surface is not in sliding contact with the partition wall 36 and deformed.

FIG. 33 is a view showing a modified example of the clamp.
Note that FIG. 33 shows only the clamp on the left side. The illustrated clamp 50A includes a lower gripping member 51 having a step 51a and an upper gripping member 52 that grips the end of the electric wire 1 between the lower gripping member 51 and the lower gripping member 51. The upper gripping member 52 includes a coil spring 54 and a base 56 that can move in the vertical direction.
The coil spring 54 is attached to the base 56.
An electric wire bending member 53 is also attached via. In the clamp 50A of this example, the base 56 descends in synchronism with the descent of the stuffer member, and the electric wire bending member 53 presses and bends the vicinity of the end of the cut electric wire 1 to cut each electric wire 1. The surface is configured to be separated from the partition wall 36 of the connector 30.

Although the embodiment of the present invention has been described above, the connector pressure welding device of the present invention is not limited to the specific mode of the embodiment, and various modifications can be made. Of course.
