Description

Connector terminal pin press with automatic stopper {CONNECTOR PIN PRESS WITH AUTO STOPPER}

The present invention relates to a press apparatus for pressurizing and crimping a connector terminal pin to fix the cable. More specifically, when the press apparatus is separated from the press jig, such as when the press is not replaced or crimped. The present invention relates to a press for connector terminal pins equipped with an automatic stopper for stopping the lowering of the movable hatch to prevent collision with the anvil.

In general, a connector terminal pin press apparatus is a device for fixing a terminal pin of the metal to the end of the cable in a conductive state, it is shown in Figures 1 to 3 of the conventional terminal pin press apparatus.

1 is an exploded perspective view showing a structure of a conventional terminal pin press, Figure 2 is a perspective view of a jig guard is inserted into the conventional terminal pin press, Figure 3 is a perspective view of a jig guard inserted into the conventional terminal pin press. 1 to 3 are excerpted from Registered Utility Model Publication No. 20-0393498, which has been devised by the present inventors.

1 to 3, the conventional connector terminal pin press, the supply unit 3 for supplying the terminal pin 1 on the base 50, the anvil 23 and the press guide (supporting the terminal pin 1) ( 2) is installed, the hatch 21 is installed in the press guide (2) to move up and down reciprocally, press the terminal pin (1) to the bottom of the hatch 21 in response to the anvil (23), A crimper 22 for crimping is installed.

When the terminal pin 1 is continuously supplied into the press apparatus by the supply device 3 at regular intervals, the hatch 21 moves up and down in the same period as the terminal pin supply period, and the crimp 22 is connected to the connecting piece. The terminal pin (1) connected to the (11) and at the same time, the terminal pin (1) to the end of the cable (not shown) by pressing and compressing to combine the terminal pin and the cable.

However, when the press device is not in use, the crimper 22 and the anvil 23 may accidentally collide with each other. In this case, the crimper 22 as well as the anvil 23 may be damaged by an impact. That is, when the press apparatus is removed from the press jig 8 (see FIGS. 4 and 5) of the crimping system due to the replacement of the press apparatus, repair, or the like, the hatch 21 falls in the press guide 2. Thus, the crimper 22 and the anvil 23 collide with each other.

In order to prevent this, the present inventors can be inserted and detached between the lower end of the screw head 29a of the height adjusting bolt 29 and the upper end of the press guide 2 as shown in Figure 2 (3) 70) to prevent accidental collision between the crimper 22 and the anvil 23 in the state in which the jig protector 70 is inserted.

However, if the jig guard 70 is not inserted by the carelessness of the operator before removing the press device from the press jig, the collision between the crimper 22 and the anvil 23 cannot be avoided, and thus the crimper 22 ) Or when the anvil 23 is deformed or broken, there is a problem in that the fixing state of the terminal pin becomes bad or cannot be used, and thus the crimp and anvil must be manufactured again.

As described above, the conventional jig protector 70 not only has a limit that cannot be prevented even by an operator's carelessness, but also is inconvenient for the operator, and thus, if the press device is detached from the press jig, it automatically creeps in any case. There is a need for a more stable device that can prevent the fur 22 and the anvil 23 from colliding with each other.

The present invention has been made to overcome the limitations of the conventional jig protector, the object of which is that as long as the press device for the connector terminal pin is separated from the press jig of the crimping system, the hatch in the press guide is not automatically lowered at the same time. It is to provide a connector terminal pin press with an automatic stopper to prevent the collision between the crimper and the anvil at the source.

In order to solve the above problems, a preferred embodiment of the present invention includes a cable terminal provided with a press guide (2) on a base (50), and including a hatch (21) for vertical reciprocating movement along the press guide (2). In the press for pins, the pin 50 is installed to be movable horizontally on the base 50 and the one end thereof is protruded from the outer surface of the base, and the lower part is in contact with the other end of the mill pin 52 and is rotatable by the hinge 41. It is installed so as to be characterized in that the upper end is made of a stopper 40 for supporting or releasing the hatch 21, and the elastic body 54 in contact with the bottom of the stopper 40 to press the mill pin 52 to the outside of the base do.

In a more preferred embodiment, the stopper 40 may further include a support portion 42 having a horizontal surface in contact with the hatch, and an inclined mill pin taper 53 is formed at one end of the mill pin 52. Can be.

According to the present invention, when the press apparatus is disconnected from the press jig which is the crimping system of the terminal pin, the lowering of the hatch is automatically prevented in connection with the press jig. The collision between them can be prevented, and the operator can perform the replacement and maintenance work of the press as conveniently.

Therefore, according to the present invention, the service life of the crimper and the anvil can be extended, safety accidents, etc. can be prevented, and unnecessary maintenance cost and time waste can be prevented, thereby reducing management and maintenance costs.

Referring to FIG. 4, as described above, the press apparatus 100 compresses the terminal pins and couples them with the connector, and the hatch 21 provided with the crimp 22 at the bottom thereof is positioned along the press guide 2. The press guide 2 is installed on the post 20 (refer to FIG. 5) installed in the base 50 so as to be reciprocated in the downward direction.

In addition, an anvil 53 for supporting the terminal pin in response to the pressurization of the crimper 22 is installed at one side of the base 40, and the driving relationship of the press apparatus 100 is illustrated in FIGS. 1 to 3. In addition, since it is described in detail in the Utility Model Publication No. 20-0393498 devised by the present inventors, further detailed description is omitted.

On the other hand, in order to reciprocally move the hatch 21 in the press apparatus 100 in the up / down direction, that is, to perform the operation of crimping the terminal pin, the press apparatus 100 is a press jig 8 which is one of the crimping systems. Should be mounted in the

The press jig 8 is provided with a work pedestal 80 in which the press apparatus 100 is placed at the bottom, and a fixing stand 81 is provided on the work pedestal 80 to contact one end of the base 50. An adjuster 82 is provided in contact with the other end of the base 50, while the upper portion of the press jig 8 is coupled to the upper portion of the height adjusting bolt 29 (see FIG. 5) of the press apparatus 100. The vertical conveyance shaft 83 which moves up / down reciprocating 21 is provided. Of course, although not shown, one side of the press jig 8 is provided with a hydraulic or pneumatic device or a motor that is a driving source of the vertical feed shaft 83.

When the press apparatus 100 is mounted on the press jig 8 as shown in FIG. 5, the base 50 is seated between the fixing base 81 and the adjusting base 82, where the base is rotated and tightened to adjust the base. 50 is firmly fixed to the holder 81 and, on the contrary, when the controller 82 is released, the fixing of the base 50 is released, and the press device 100 can be separated from the press jig 8. .

According to the present invention, when the press apparatus 100 is separated from the press jig 8 as shown in FIG. 4, a means capable of preventing the fall of the hatch 51 separated from the vertical feed shaft 83 is provided. This will be described with reference to FIGS. 6 to 9.

Figure 6 is a front view showing a state in which the stopper of the terminal pin press according to the present invention is released, Figure 7 is a side view showing a state in which the stopper of the terminal pin press according to the present invention is released, which is the press apparatus 100 press It is a state mounted on the pedestal 80 of the jig. In the drawings, some unnecessary devices or parts are not shown in order to help understanding the automatic stopper operation relationship according to the present invention.

As shown in Figure 6 and 7, the automatic stopper device of the present invention is largely installed in the base 50 so as to be horizontally movable, one end is protruded from the outer surface of the base pin 52 and the lower pin (52) A stopper 40 which is in contact with the other end of the side and is rotatably installed by the hinge 41 and the upper end supports or releases the hatch 21 according to the rotation, and the bottom end of the stopper 40 is in contact with the mill pin 52 of the base. It is roughly divided into the elastic body 54 which presses outward.

The mil pin 52 can be reciprocated in a horizontal direction in the horizontal direction in the working space 51 in the base 50, wherein one end of the mil pin 52 protrudes a certain distance from the outer surface of the base 50 at any position When external force acts, it is drawn inside.

The stopper 40 is installed in the vertical direction, and the middle part is fixed to the post 20 by the hinge 41, and thus, the pivoter 40 can rotate at a predetermined angle about the hinge 41.

In addition, the elastic body 54 may be a spring or other form of a coil form, is installed in the innermost of the operating space 51 of the base 50 to provide an elastic force in one direction to the lower portion of the stopper 40 The pin (52) is always pushed out of the base (50).

In such a structure, when the press apparatus 100 is mounted to the press jig 8, the base 50 is interposed between the fixing base 81 and the adjusting unit 82 to be fixed without moving, and the adjusting unit 82 Milpin 52 in contact with the end of the) moves into the base 50.

Accordingly, the stopper 40, which is in contact with the other end of the mill pin 52, rotates at an angle about the hinge 41, and the upper end of the stopper 40 is reciprocated in the up / down direction. Since it is out of the region, the movement of the hatch 21 is not prevented. Accordingly, the operation of fixing the terminal pin to the cable may be performed by the movement of the hatch 21.

8 and 9, when the press apparatus 100 is detached from the press jig 8, the base 50 deviates between the fixing base 81 and the adjusting unit 82, and in this case, the elastic force of the elastic body 54. The stopper 40 returns to its original position and returns to a vertical state. At the same time, the mill pin 52 moves horizontally with an elastic force so that one end portion protrudes to the outer surface of the base 50.

In this case, since the upper end of the stopper 40 is in contact with the lower end of the hatch 21 to prevent the hatch 21 from moving downward (falling), it is possible to prevent the crimp 22 and the anvil 23 from colliding with each other. .

As such, in the present invention, the stopper 40 is operated by the movement of the mil pin 52 and the elastic force of the elastic body 54, which is interlocked with a state in which the base 50 is mounted or not mounted on the pedestal 80. It works automatically, eliminating accidental concerns due to operator's negligence or mistake.

In a more preferred form, as shown in Figure 8 to form an inclined mil pin taper 53 at the outer end of the mil pin 52, when mounting the base 50 on the pedestal 80, The ends and the ends of the mil pins 52 minimize collision or misalignment with each other and allow the mil pins 52 to be pushed in naturally. Of course, it is more advantageous to install the inclined taper 82 'as shown in FIG.

In addition, a support portion 42 having a horizontal plane may be formed on the top of the stopper 40 in a manner such as bending about 90 degrees with respect to the vertical stopper 40. Since the support part 42 having the horizontal surface is in contact with the lower end of the hatch 21 in a larger area, the hatch 21 can be stably supported.
