Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method and apparatus for automatically inserting a wire terminal into a connector housing.

Conventionally, the process of inserting a terminal with a wire into a connector housing has been done manually, but when inserting the terminal manually, there is a risk of errors due to incorrect insertion, especially when inserting a terminal with a wire into a housing with a large number of pins. Not only does it have many drawbacks, such as terminal deformation due to wiring, incomplete insertion, missing insertion, incorrect insertion, or deformation of the terminal during transportation to the process of inserting the terminal with electric wire into the housing, but it does not allow for accurate and quick insertion. It requires a considerable amount of skill to master.

In view of the various drawbacks associated with the conventional manual insertion of a terminal with a wire into a connector housing, the present invention solves the above problems by automating this insertion process, and achieves an accurate and quick method. The object of the present invention is to provide a method and apparatus for automatically inserting a terminal with an electric wire into a connector housing, which allows stable insertion and does not cause loss such as terminal deformation.

The operation of the present invention and the entire apparatus will be explained in order below with reference to the operation explanatory diagrams shown in FIGS. 8 to 18.

First, as shown in FIG. 1, the terminal W2 with wire attached by the terminal crimping device C, gripped by the clamp 3 of the conveying lamp chain, and transferred by the wire is transferred in the case fitting process of the terminal with wire of the present invention. Terminal 7 by insertion device
In order to make it easier to hold, the terminal with wire W2 is pulled back by a certain amount by the terminal with wire pull-back device shown in FIG. Figure 8 fa) shows the state before the terminal with wire is pulled back, (
b) shows the state after the terminal with electric wire has been pulled back, and the electric wire gripping claw 11 of the terminal with electric wire pull-back device can be freely moved and opened/closed in the longitudinal and vertical directions by the cylinders 17 and 19 and the short cylinder 22. When operated, the terminal W2 with electric wire is pulled back to the state shown in FIG. It will be done.

Next, the pulled-back terminal W2 with an electric wire is transferred to a process of fitting the terminal into a case, and the terminal and the electric wire of the terminal with an electric wire are respectively grasped by the insertion device E of the present invention shown in FIG. The holding device F) is transported and inserted into the case I set in advance on the housing fixture 75. This operation will be explained in more detail below.

That is, the terminal with wire W2 pulled back by the pull-back device for the terminal with wire has the terminal 7 pulled back by the terminal guide plate 9 as shown in FIG.
0 and transferred to a predetermined position on the transport lamp chain, the terminal gripping claws 35 and the wire gripping claws 36 of the insertion device E are freely operated by the cylinders 43 and 45, and each gripping claw holds the terminal with wire. It is held at a predetermined position corresponding to W2, and the respective gripping claws 35 and 36 are simultaneously lowered. Next, the terminal gripping claw 35 and the wire gripping claw 36 are opened and closed by the above-described operations, and the terminal and the wire are held together so that the head of the terminal 7 protrudes a certain amount from the terminal gripping claw 35 as shown in FIG. to grasp at the same time.

Next, after the terminals and wires are grasped, the transport ramp 3 is opened and the cylinder 4.3 of the insertion device E is opened as shown in FIG.
, 45 to open the terminal gripping claw 35 and wire gripping claw 36.
is moved to the case position previously set in the housing fixture 75 of FIG. 6, and stopped at an upper position corresponding to a predetermined insertion point. Next, as shown in FIG.
2 is lowered to a position facing the terminal accommodating chamber of the case H, and then moved forward by the cylinder 56 in the direction of the arrow on the case side. Next, as shown in FIG. 13 (fal), when the tip of the terminal gripped by the terminal gripping claw 35 is inserted into the terminal accommodating chamber of the case H, the forward movement of both gripping claws is stopped, and as shown in FIG. As shown in , the terminal gripping claw 35 is opened and raised. This is to prevent the terminal gripping claw 35 from getting in the way when the terminal 7 is reinserted using the wire gripping claw 36. In this case, The tip of the terminal 7 is the case 14

(2) The outer frame is attached to the fixed plate so as to be movable left and right, and has a wire gripper and a terminal gripper that can move up and down inside, respectively.The outer frame is opposed to the fixed connector housing, and is attached to the wire gripper. After the electric wire and the terminal of the terminal with electric wire are respectively gripped by the electric wire gripping claw attached to the wire gripping claw and the terminal gripping claw attached to the terminal gripping tool, the outer frame is brought close to the connector housing, and the tip of the terminal is brought closer to the connector housing. When the terminal is close to or located in the terminal housing chamber, the terminal gripping claw opens and the terminal gripping claw is raised, and then the wire gripping claw gripping the wire approaches the connector housing, and the terminal with the wire is removed from the connector housing. After the locking is completed, the outer frame is fixed in the terminal housing chamber.
A method for inserting a terminal with an electric wire into a connector housing, which comprises moving the terminal with an electric wire to a pitch and sequentially inserting and locking the terminal with an electric wire into the terminal housing chamber. (3) A wire gripping tool and a terminal gripping tool fitted in a vertically movable manner are provided inside an outer frame that is mounted on the fixed plate so as to be movable left and right, and the wire gripping tool and the terminal gripping tool An apparatus for inserting a terminal with an electric wire into a connector housing, characterized in that a wire gripping claw and a terminal gripping claw are provided at the lower end, respectively, and the outer frame is mounted on a movable table so as to be movable back and forth and up and down.
