However, in the housing reversing device described in Patent Document 1 and the terminal insertion method using the same, the work of reversibly mounting the housing holding frame on the vertical housing holding plate (replacement) is troublesome. There is a concern that it takes a lot of time to deal with a large number of connector housings of different types (may be several types). Also, in order to move the housing holding plate to the left and right (housing alignment direction) and to reverse the required housing holding frame with the rotary cylinder on the fixed side, the housing holding plate is moved to the left and right There was concern that it would take a lot of space and time to move to.

Further, in the terminal insertion device and the terminal insertion method described in Patent Document 2, the width dimension in the left-right direction of the pair of left and right guide arms for separating the electric wires is wide (for example, wider than the width of the terminal). There is a concern that when the pitch between the left and right terminal accommodating chambers of the connector housing is narrow, the wires cannot be scraped well.

In view of the above, the present invention provides a housing reversing device that can perform reversal of a connector housing in a short time and in a short time corresponding to a large number of connector housings, and a connector using the housing reversing device. It is a first object of the present invention to provide a terminal insertion method capable of smoothly inserting a terminal into the upper and lower terminal accommodating chambers of the housing without interference with the upper inserted electric wire with a terminal. Further, in the above terminal insertion method, the terminal-attached electric wires already inserted into the left and right narrow-pitch terminal accommodating chambers are smoothly and reliably scraped by the electric wire scraping arm, and the terminals are smoothly and surely inserted into the intermediate terminal accommodating chamber. It is a second object of the present invention to provide a terminal insertion method that can be used.

In order to achieve the above object, a housing reversing device according to claim 1 of the present invention is provided with a number of holder supports arranged and fixed in parallel on a horizontally long horizontal base plate, and can be turned upside down on each holder support.

A terminal with an electric wire is inserted into the cable.

With the above configuration, the terminal-attached electric wire already inserted into the upper terminal accommodating chamber is turned upside down to hang down from the lower terminal accommodating chamber, and an obstructive electric wire is placed in front of the new upper terminal accommodating chamber. A large space is secured by disappearing. Thereby, the terminal with the electric wire is smoothly and surely inserted into the new upper terminal accommodating chamber without interfering with the already inserted electric wire with the terminal. This cycle is repeated, so that the terminals with electric wires are smoothly and surely inserted into all the required upper and lower terminal accommodating chambers. There may be a case where the connector housing is turned upside down after inserting the terminals with electric wires into two or more terminal accommodating chambers in the upper left and right direction (a plurality of terminals may be inserted in one cycle). .

The terminal insertion method using the housing reversing device according to claim 3 is the terminal insertion method using the housing reversing device according to claim 2, wherein the pair of left and right thin rod-shaped wire scraping arms are wrapped back and forth to provide the required terminals. Insert between the inserted electric wires with terminals located on the left and right sides of the storage chamber, open the electric wire scraping arm and scrape the inserted electric wires with terminals, and insert the electric terminals with electric wires into the required terminal accommodating chamber It is characterized by that.

With the above configuration, the pair of left and right thin rod-shaped wire scraping arms wraps back and forth (overlapping or aligning), and the width of the pair of wire scraping arms is defined to be narrow. Between the already inserted electric wires with left and right terminals, it is smoothly and reliably inserted downward from above, so that the electric wires with terminals on the left and right sides are surely separated.

According to the first aspect of the present invention, one driven body is moved in the longitudinal direction of the base plate, that is, the aligned direction of the driven bodies, without moving the driven body including a plurality of housing holders on the base plate.

Also, already inserted terminal 17 with electric wire 16 to the terminal accommodating chambers 13 ₃ adjacent to the left and right of the required terminal receiving chambers 13 ₃ of the third stage from the top in a state of pushing aside by the wire pushing aside the arm 16 in FIG. 5, the upper It is also possible to insert the terminal 17 with the electric wire 16 into the terminal

accommodating chambers

13 ₂ and 13 ₄ in the middle of the second to fourth stages.

The terminals 17 with the wires 16 are smoothly inserted into the terminal housing chamber 13 in the vertical direction of the connector housing 2 by the terminal insertion method of FIGS. 1 to 4, and the terminals of the connector housing 2 in the horizontal direction are accommodated by the wire scraping arm 25 of FIG. The terminal 17 with the electric wire 16 is smoothly inserted into the chamber 13.

Each wire scraping arm 25 is narrower than the width of the terminal accommodating chamber 13, is approximately as thin as the wire 16, is approximately as short as the height of the connector housing, is formed in a thin rod shape with a circular cross section, (Lower end) The taper is tapered toward the 25a.

The pair of wire scraping arms 25 is in a state where the lower end side is opened slightly outward from the vertical (vertical) in the open state, and the scraped wires 16 are securely held by the outer surface 25b of the wire scraping arm 25 without dropping off, While the left and right wire scraping arms 25 are closed, the thin tip portions 25a of the respective wire scraping arms 25 coincide with the front and rear while wrapping back and forth, and smoothly between the wires 16 with the terminals 17 already inserted from above. And it can be easily inserted.

The upper end portion (base portion) 25c of the left wire scraping arm 25 is integrally bent to the rear half portion 30a of the upwardly inclined plate portion 30 thicker than the wire scraping arm 25 while bending outward. The front half portion 30b has a notch step portion 31 that faces the front side of the upper end portion 25c of the wire scraping arm 25. When the left and right wire scraping arms 25 are closed, the left half wire scraping portion faces the right side of the notch step portion 31. The right electric wire scraping arm 25 wraps (overlaps) on the front side of the arm 25 and is arranged in the front-rear direction.

The upper end portion 25c of the left electric wire separating arm 25 is positioned so as to face the notch step (31) (not shown) in the first half of the upward inclined plate portion 30 following the upper end portion 25c of the right electric wire separating arm 25.

The left and right plate portions 30 are fixed to the vertical flange portions 32 by screwing or the like. Each of the left and right flanges 32 is driven to open and close in the left-right direction as indicated by an arrow F by a drive unit such as a horizontal air cylinder or motor (not shown) and a short guide rail, and the air cylinder or It is driven up and down as indicated by an arrow E by a drive unit such as a motor, and further driven forward and backward as indicated by an arrow G by a drive unit such as an air cylinder or a motor along a longitudinal guide rail.

In FIG. 5, the pair of left and right wire scraping arms 25 are closed and wrapped back and forth (overlapping or aligning), thereby reducing the width in the left-right direction of both wire scraping arms 25 (half the width when arranged in parallel on the left and right) is reduced to), that the arm 25 pushing aside both wire in this state is moved to the front of the required terminal receiving chambers 13 ₃ downward in the connector housing 2 from above as shown by the arrow E, already with the inserted left and right terminals 17 The electric wire scraping arm 25 is inserted between the electric wires 16 smoothly and reliably.

Then paving the pair of electric wire pushing aside the arm 25 is left as shown by the arrow F, to move from the front opening as the terminal accommodating chamber 13 ₃ of arrow G to the front (direction away horizontally), or a pair of wire pushing aside the arms while moving from the front opening as the terminal accommodating chamber 13 _third arrow G in a state where 25 is closed at the front (direction away), open to the left and right as indicated by arrow F, the left and right already inserted terminal 17 with electric wire 16 Scrap left and right. At this time, since the electric wire 16 led forward from the terminal accommodating chamber 13 of the connector housing 2 hangs downward due to its own weight, the pair of electric wire scraping arms 25 are moved in the direction of arrow E by the extension operation of a vertical air cylinder (not shown). And move forward as indicated by arrow G. Thereby, the electric wire 16 with the terminal 17 can be smoothly and reliably scraped left and right with a small force without applying a load to the root portion (terminal) 16a of the electric wire 16 with the terminal 17 already inserted.

A wide empty space 29 is secured in front of and in the vicinity of the required terminal accommodating chamber 13 ₃ , and in this state, the terminal 17 with the electric wires 16 is connected to the required terminal accommodating chamber 13 _{3 by} a gripping arm of a terminal insertion head (not shown). Insert it smoothly and securely.

The wire gripping arm at the initial position of the terminal insertion head is positioned in front of the wire scraping arm 25. The wire scraping arm 25 is disposed integrally with the terminal insertion head and forms a part of the terminal insertion head. It is also possible to replace the connector housing 2 having the upper and lower four-stage terminal accommodating chambers 13 in FIG. 5 with the connector housing 15 having the upper and lower two-stage terminal accommodating chambers 14 in FIG. It is also effective to use the terminal insertion method or terminal insertion device of the embodiment of FIG. 5 independently of the housing reversing device 1 of the embodiment of FIGS.
