Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a connector connection device for connecting an electrical connector to a cable. Recently, small connectors such as those described below have begun to be widely used for connecting telephone handsets. As shown in the perspective view, plan view, cross-sectional view, and cross-sectional view showing the cable connection state shown in FIGS. blind hole 3
and a cable fixing piece 5 supported by a thin piece 4a in a fixing hole 4 wider than that of the blind hole 3 located on the cable sheath 2a inserted therein; It is located on each strand of the cable with the sheath 2b inserted into the hole 3 and penetrates into the blind hole 3 from the upper surface of the insulating block 1. For example, it consists of insertion/removal through holes 6 for four contact member pieces and four contact member pieces 7. To connect the cable, after inserting the cable into the blind hole 3 as shown in Fig. 1d, press the cable fixing piece 5 to cut the thin piece 4a, and fix the fixing piece 5 with a width smaller than that. Drive into the blind hole 3 of the width, and insert the cable jacket 2
A is clamped and fixed between the fixing piece 5 and the lower surface of the blind hole 3. At the same time, the contact member piece 7 inserted in advance into the insertion through hole 6 is inserted so that its sharp tip end 7a penetrates the coating 2b of each strand, and the core wire 2c
It is connected by driving it in so that it reaches . Then, for example, by fitting the plug connector 8 to which this cable is connected into a receptacle connector (not shown), the protruding end 7b of the contact member piece 7 is brought into contact with the contact member of the receptacle connector,
This connects the handset to the telephone body. Note that 1a is a locking piece for the receptacle connector. By the way, the size of this type of connector is for a 4-core cable, for example, 1.2 cm in length and 1.2 cm in height.
It is extremely small, measuring about 0.6cm and 0.7cm wide. Therefore, the dimensions of the contact member piece 7 are also extremely small, with a width of 0.2 cm, a height of 0.4 cm, and a thickness of about 0.02 cm. Correspondingly, the dimensions of the through hole 6 for inserting the contact member piece are also extremely small. For this reason, assembling each part by hand becomes extremely troublesome, time-consuming, and expensive. Therefore, research has recently been conducted into mass production methods using connector connection devices, but the conventional methods have various drawbacks and are not satisfactory. For example, as a typical example, a schematic perspective view shown in FIG. 2 is used. This involves sending the connectors 8 of the connector series 9 to one location and fixing them on the stand 10, and then automatically disconnecting them.
After manually inserting the cable 2 into the blind hole 3, a press device (not shown) drives the contact member piece 7 inserted in advance into the insertion through hole 6 and pushes the cable fixing piece 5. The driving hammer body 11 and the pushing hammer body 12 are operated simultaneously and all at once for connection. However, with this device, the contact member piece 7 is thin and small, making it difficult to even pick it up with a fingertip.
There still remains the tedious and time-consuming manual work of inserting each one into the insertion through-hole 6 of the same size. Therefore, not only is the cost not reduced sufficiently, but there is a very large possibility that the contact member piece 7 will be inserted upside down when it is inserted. For this reason, the sharp end portion 7a of the contact member piece 7 is not driven into the strand 2d, which often results in a poor connection, and there is a disadvantage in that it takes more time to make the connection in order to take this into account. The present invention provides a highly productive connector wiring device that is capable of automatically inserting a contact member piece into an insertion through hole, which is extremely troublesome as described above and has a high risk of defective connection. The purpose of this invention is to explain the details with reference to the drawings. The main points of this proposal are as follows. That is, as shown in the perspective view in FIG. 3, the contact member piece 7 is
A series of contact member pieces 13 are connected in series by connecting pieces 13a, and one of the contact member pieces 7 is sequentially stepped onto the insertion through hole 6 of the connector 8 fixed on the fixed base 14. Form it so that it is rolled out (see arrow). On the other hand, in connection with the stepwise feeding out of the contact member piece series 13, the connector fixing base 14 is moved as shown in FIG.
As shown in the plan views shown in b, c, and d, the installation interval pitch S of the insertion through hole 6 of the connector 8 is stepped in the direction of the arrow in the figure, which is perpendicular to the feeding direction of the contact member piece series 13. Formed so as to be offset. When the first contact member piece ₇₁ is positioned close to the first insertion through hole ₆₁ as shown in FIG. 4a by the first feeding, it is separated by the cutting body 67 shown in FIG. At the same time, the contact member piece 7 ₁ is covered with the cable ₂ by the driving body 22 and the pushing body 23 that descend in the direction of the arrow in the figure using a press device (not shown). 2b to make the connection, and at the same time push in the fixing piece 5 to fix the cable 2. Then, the fixed base 14 moves by one pitch S as shown in FIG. 4b, and when the next contact member piece series 13 is fed out, the second contact member piece 7 ₂ and the insertion through hole 6 ₂ are brought into alignment. As shown in FIG. 3, only the cutting and driving of the contact member piece 72 by the cutting blade 67 and the driving body ₂₂ is performed so that the pushing body 23 escapes from the press device in the direction of the arrow in the figure and becomes inactive. Then, in the same manner as shown in FIG. 4c and d, each time the connector 8 for one pitch S moves, the third and fourth contact member pieces 7 ₃
Cutting and driving into the insertion through holes 6 ₃ and 6 ₄ of 7 ₄ are performed to complete the operation of connecting the cable to one connector. In this way, only the operation of fixing the connector 8 with the cable 2 inserted into the blind hole 3 on the fixing base 14 is necessary, and the manual insertion of the contact member piece, which is troublesome and likely to lead to poor connections as described above, is required. Connections are automatically made without any additional steps, making it possible to mass-produce connections. In the above explanation, the connectors were fixed to the fixing base manually, but as in the conventional technology shown in Fig. 2, a series of connectors is formed and the connectors are automatically fixed to one location on the fixing base. A method of feeding and fixing may also be adopted. However, since it is necessary to insert the cable into a blind hole, there is almost no difference in time even if the connectors are fixed one by one. Next, the present invention will be explained using examples.

As shown in FIG. 6c, there is a feeding path 51 having a cross section that allows the contact member piece series 13 to be fed smoothly, and one end of which is bent at a curvature that does not impede feeding. The connector 8 is fixed on the fixing base 14 so as to be opened in front of the first insertion through hole 6 ₁ . Returning to FIG. 5, reference numeral 52 is a sending arm of the contact member series, and 53 is a guide member thereof, which is fixed to the base A. 54 is a return spring provided between the feed arm and the base; 55 is an operating roller rotatably fixed to one end of the feed arm 52; and 56 is fixed to the other end of the feed arm 52 so as to be perpendicular thereto. The feed support is L-shaped as shown in Figure 6d, and one end is rotatably fixed to the horizontal part.
The feed claw plate 5 is pulled upward by the spring body 57.
It has 8. This is formed so as to enter the gap 13b of the contact member piece 7 of the contact member piece series 13 through a hole (not shown) provided in the lower part of the feed path 51. Returning to Fig. 5, 59 is the feed arm operating column;

When the support plate B rises and the curved surface 59a separates from the actuating roller 55, the return spring 54 returns the feed arm 52 to its original position and advances the feed claw 58 in the feed direction to move the contact member piece 7. The relative position of the actuating roller 55 and the curved surface 59a of the feed arm actuating column 59 is selected so that the feed is carried out after the contact member piece 7 is driven by the driving body 22 onto the connector 8 addressed to one part. be done. In addition, in FIG. 6d, reference numeral 60 denotes a return prevention pawl, which is pushed upward by a spring 61 and enters the gap 13b of the contact member piece 7, and the feed pawl 58
When the contact member series 13 is returned in a direction opposite to the feeding direction, the contact friction between the feed pawl 58 and the contact member series 13 prevents the contact member segment series 13 from returning. Returning to FIG. 5, numerals [ ] indicate the cutting portions of the contact member pieces, of which 62 is a cutting arm and 63 is a guide thereof, which is fixed to the base A. 64 is a return spring provided between the cutting arm and the guide body, and 65 is an operating roller, which is rotatably fixed to one end of the cutting arm 62. 6
Reference numeral 6 denotes a cutting arm actuating column which is fixed to the support plate B, and when the support plate B is lowered, its curved surface 66a becomes the actuating roller 6.
5 in the direction of arrow _c2 in the azimuth diagram to move the cutting arm 62 in the same direction. Then, as shown in the plan view shown in _FIG . The series of contact member pieces 13 sandwiched between them is cut at the connecting piece 13a and inserted into the insertion through hole 6 of the connector 8 , and the operation is performed by the feeding section [ ]. After feeding out only one contact member piece 7 of the series 13, the actuating roller 6
The relative position of the curved surface 66a with respect to 5 is selected.
The sequential operations of the pistons, the press device for driving the support plate, etc. in each of the above parts are automatically performed using a sea case control device (not shown). An embodiment of the present invention has been described above, but when cutting a series of contact member pieces, the cut contact member pieces tend to move somewhat in the cutting direction, so as shown in FIG. It is preferable to shift the feeding position of the contact member piece series 13 to some extent. Also, the above is 4
Although the connection of a 6-core or 8-core cable connector has been illustrated, there is also a connector that has the same width as the insulating housing 1 and is capable of connecting 6-core or 8-core cables. In this case, as shown in FIG. 8a, the length l between the side surface of the insulating housing 1 and the first insertion through hole ₆₁ is different. Therefore, when this is fixed to the fixing base 14 shown in FIG. It becomes difficult to connect and it becomes difficult to connect.
Therefore, for example, if you want to share the connector connection device for 4-core and 6-core, the sawtooth plate 49 explained in FIG. 6b has additional teeth σ, σ',
By providing θ, θ' and ρ, ρ', ω, ω' and adjusting the respective tooth intervals, in the case of 4 cores, the teeth γ, γ' and the saw teeth 43a, 44a of the feed control tooth plates 43, 44 are adjusted. When the fixed base pitch moving plate 38 starts to move from the engagement position and the sawtooth 43a engages with the tooth α, the driving operation by the support plate B is performed.
In the case of 6 cores, a fixed base pitch moving plate 38 and a feed control tooth plate 43, 44 by pistons 40, 46
By the preliminary control, the tooth 43a is set to be engaged at θ as shown by the dotted line in FIG. 8b,
The operation may be started from this point, and the driving operation by the support plate B may be started when the tooth 43a engages with the tooth α. In this case, it goes without saying that the number of times the support plate B is lowered is set to vary depending on the number of cores. Another method is to install the fixing base 14 in different sizes depending on the size of the connector to be fixed, so that the first insertion through hole is always located at a predetermined location regardless of its position from the insulating housing. You may also do so. Also sawtooth plate 49
By changing the length, it can be used for connectors with different core wire arrangement pitches. As is clear from the above explanation, according to the present invention, the connector can be automatically and quickly connected to the cable by simply setting the connector into which the cable is inserted, so the cost required for connection can be greatly reduced. In addition, since the contact member piece is inserted into the insertion through hole automatically, there is no risk of incorrect connection due to incorrect insertion direction of the contact member piece, and excellent effects such as reliable connection are achieved. This is something that can be used in practice and has great effects.
