Description

  The present invention is formed, for example, by intermittently feeding a metal strip having a connector terminal portion formed by press molding or the like in a so-called progressive die, and cutting the metal strip to a predetermined length in the middle thereof. The present invention relates to a method for manufacturing a strip-shaped member with a terminal row, a strip-shaped member with a terminal row, and a mold, in which the terminal row members are sequentially connected to the connecting member at a predetermined interval, and in particular, the material yield. The present invention proposes a technology that contributes to the improvement of manufacturing efficiency and the quality of products while effectively preventing the deterioration of the product.

Conventionally, in manufacturing a connector made of a copper alloy or the like, a method as schematically shown in a plan view in FIG. 4 is sometimes used.
That is, according to this method shown in FIG. 4, first, the required pressing and plating processes are performed on a flat planar long metal plate intermittently fed in one direction in a progressive die. Then, a metal strip 100 as shown in FIG. In this metal strip member 100, a plurality of connector terminal portions 102 extending from both of the side portions 101 toward the inner side in the width direction of the metal strip member 100 in the direction opposite to each other are provided on both side portions 101. Along the longitudinal direction of the material 100, the material 100 is arranged closely at a narrow interval.

Next, for example, as shown in FIG. 4B, unnecessary terminal portions 102a are cut and removed, and a predetermined number of terminal portions 102b are left at a constant interval, and a predetermined number of these remaining terminal portions 102b are gathered together. The terminal row 103 is assumed.
Thereafter, as shown in FIG. 4C, insert molding for sealing the distal end side of the connector terminal portion 102b with the resin material 104 is performed for each terminal row 103, and the length of the resin material 104 is increased. Support metal fittings 105 are disposed at both ends in the direction, and the resin material 104 is pressed together with the sealed terminal portions 102b by the support metal fittings 105. Thereafter, the metal strip 100 is conveyed to a portion where the next process is performed.

  By the way, in such a manufacturing method, since it is supposed to perform continuously from press molding to insert molding, without changing the feed mode of the metal strip 100 in the same progressive die, insert molding Thus, as shown in FIG. 4B, the terminal portion 102a that becomes an obstacle when the terminal row 103 including the predetermined number of terminal portions 102 is sealed with the resin material 104 is cut and removed as shown in FIG. As a result, there is a problem that the yield of the material is inevitably lowered.

On the other hand, Patent Document 1 discloses a method in which a connector terminal row is sequentially insert-molded in a part of a structure by progressive intermittent feed, and a predetermined number of terminals are provided at a predetermined pitch on one side of a substrate. Positioning holes are drilled at predetermined positions on the substrate in the terminal row connecting pieces that are connected in parallel with each other. On the other hand, pilot holes are drilled in inexpensive thin metal strips, and at the same time, the pilot hole position is used as a reference. A small protrusion is protruded on one surface of the metal strip at a predetermined position, the positioning hole is fitted into the small protrusion, and the terminal connecting pieces are sequentially crimped along the longitudinal direction of the metal strip. There has been proposed a method of forming a structure which is connected to a predetermined position and is used as a progressive carrier for connector terminals and which includes a connector terminal row in part.
And according to this method, “the use of expensive terminal members as waste materials is extremely reduced, the resource saving is achieved, the cost is reduced, and the productivity can be improved efficiently”. ing.

  In this regard, Patent Document 2 discloses that an insulator includes a shell that covers the insulator, a male contact that is partially exposed from the insulator, and a printed circuit board that is exposed from the insulator. A method for manufacturing an I / O connector in which a holddown that is fixed and a lock bracket that engages with a mating claw of a mating connector are assembled, and a part other than the shell is used as an insert metal as an insulator There is described a method for manufacturing an I / O connector in which an integral molding is attached and then an unnecessary portion of the insert metal in the insulator is cut and a shell is attached to the insulator.

However, in the method described in Patent Document 1, as clearly shown in FIG. 1, the metal strip and the strip-shaped carrier are caused to run in parallel with each other at intervals. In order to connect the terminal array member formed by cutting from the material to the strip carrier, the terminal array member formed by cutting needs to be conveyed toward the strip carrier in a direction substantially perpendicular to the feeding direction of the metal strip. There is. Therefore, the terminal row member formed from the metal strip cannot be smoothly transferred to the belt-like carrier, resulting in a decrease in manufacturing efficiency, and the connection position of the terminal row member to the belt-like carrier. There is a problem that the accuracy is lowered, and thus the quality of the product cannot be denied.
In addition, in the method of Patent Document 1, cutting of the metal strip and joining of the terminal array member to the carrier cannot be performed in the same mold, and thus one step is added. In addition, it is necessary to convey the terminal array members in a substantially orthogonal direction, and there are problems in any of quality, productivity, and cost.

  The present invention aims to solve such problems of the prior art, and its object is to form a terminal array member formed by cutting a metal strip prior to insert molding. In order to connect the terminal row members smoothly and with high accuracy, after effectively preventing the decrease in the material yield due to the removal of unnecessary terminal portions, It is an object of the present invention to provide a method for manufacturing a strip-shaped member with a terminal row, a strip-shaped member with a terminal row, and a mold, which can improve the production efficiency and improve the quality of the product.

  The manufacturing method of the strip-shaped member with a terminal row according to the present invention intermittently sends a metal strip formed with a plurality of connector terminal portions arranged in parallel along the longitudinal direction, along the longitudinal direction, and In the middle, the metal strip is cut into a predetermined length, and each of the terminal row members obtained thereby is sequentially connected to the connecting member at a distance from each other to produce a strip-like member with a terminal row. In doing so, the connecting member is sent to the front side of the cutting direction of the metal strip material in the feeding direction of the metal band material, and the terminal array member cut and formed at a position on the front side of the cutting direction of the cutting direction of the metal band material. Is connected to the connecting member disposed between the adjacent terminal row members, for example, the connecting member and the terminal row member connected to each other are moved in parallel with the feeding direction of the metal strip. . Here, preferably, the feeding direction of the metal strip and the moving direction of the connecting member and the terminal array member connected to each other are arranged in a straight line in plan view.

  In connecting the connecting member and the terminal row member, for example, a concave portion formed by pressing a punch or other pressing portion is formed on both the overlapping connecting member and the terminal row member. It is preferable to perform mechanical connection such as so-called caulking, or connecting members and terminal row members, or press-fitting to connect the members by frictional engagement between the recesses.

Preferably, the connector terminal portion of the metal strip is formed so as to extend from both sides of the metal strip in a direction facing each other toward the inside in the width direction of the metal strip. The connecting member is sent from each side of the metal strip toward the front side of the cutting portion in the feeding direction.
It is preferable that the manufacturing method described above is to manufacture a band-shaped member with a terminal row used for insert molding in which the terminal portion is sealed with a resin material.

Further, the strip-shaped member with terminal rows of the present invention is configured such that a plurality of terminal row members each having a terminal row composed of a plurality of connector terminal portions arranged in parallel along the longitudinal direction are spaced apart from each other in the longitudinal direction by a connecting member. In this case, a plurality of the connecting members are provided between the adjacent terminal row members so as to connect the adjacent terminal row members to each other.
Here, it is preferable that the connecting member and the terminal array member are mechanically connected to each other. Preferably, the band member with a terminal row is formed by sealing the terminal row of the terminal row member with a resin material.

  In addition, the mold of the present invention can suitably carry out the above-described manufacturing method, and a band material conveying means for intermittently feeding a metal band material along its longitudinal direction, and in the middle of the conveying means A cutting part that is provided and cuts the metal strip into a predetermined length to form a terminal row member, a member conveying means for sending a connecting member connected to the terminal row member, and a predetermined interval. And a moving means for moving the band-like member with the terminal row formed by connecting the connecting member to the terminal row member that has been cut and formed at a position on the front side of the cutting direction of the metal strip in the feeding direction. The connection part which connects the made terminal row | line | column member with the said connection member arrange | positioned between this adjacent terminal row | line | column member is provided.

According to the manufacturing method of the strip-shaped member with a terminal row of the present invention, the connecting member is fed to the front side in the feeding direction of the metal strip material of the cutting portion of the metal strip material, and the front of the cutting portion in the feeding direction At the position on the side, the cut terminal row member is connected to the connecting member disposed between the adjacent terminal row members, and the connecting member and the terminal row member connected to each other are By moving in parallel with the feed direction, the metal strip and the strip with terminal row are not greatly changed from the cutting step of the metal strip to the connecting step between the terminal row member and the connecting member. The member will be fed.
Thereby, since the connection between the terminal row member cut and formed from the metal strip and the connecting member is smoothly performed, the production efficiency can be increased, and the connection is performed with high accuracy. The product quality can be greatly improved.
In this method, unnecessary terminal portions are not removed, so that the yield is not reduced.

It is a top view shown about one Embodiment of the manufacturing method of this invention. FIG. 2 is a schematic cross-sectional view taken along line II-II in FIG. 1, showing a connection mode between a terminal row member and a connection member that can be used in the method shown in FIG. 1. It is a partial expansion perspective view of the strip | belt-shaped member with a terminal row | line | column which can be manufactured with the method shown in FIG. It is a schematic plan view which shows the conventional method.

Embodiments of the present invention will be described below with reference to the drawings.
In FIG. 1, reference numeral 1 in FIG. 1 denotes a large number of, for example, a flat strip-like long metal plate that is pressed in the preceding process and arranged in parallel along the longitudinal direction (vertical direction in the figure). The connector terminal portion 1a is formed, and the connector terminal portion 1a is shown as a metal strip that is plated as required.
The metal strip 1 is intermittently fed at a predetermined pitch, for example, by a wire tension or a conveyor belt or the like along the vertical direction as indicated by an arrow A in FIG. .

  The metal strip 1 shown in the figure is a pair of side portions 1b extending in the longitudinal direction by being spaced apart from each other in the width direction of the metal strip 1 (left-right direction in FIG. 1) by pressing in the previous step. And a connector terminal portion 1a extending from each of the side portions toward the inner side in the width direction of the metal strip 1 in a direction facing each other.

  When such a metal strip 1 is subjected to insert molding for sealing a terminal row composed of a predetermined number of connector terminal portions 1a with a resin material in a continuous form in a strip shape, terminal portions adjacent to those terminal rows are formed. Therefore, it is inevitable that the yield is lowered by cutting and removing many of these unnecessary terminal portions.

Therefore, here, for example, the metal strip 1 intermittently fed by the cutting part 10 having a cutter or the like of a progressive die, for example, has a predetermined length including the required number of terminal portions 1a along the width direction. The terminal row members 2 obtained thereby are sequentially connected to the connecting member 3 conveyed from the other side with a predetermined distance d from each other. It is preferable that the space | interval d here shall be the magnitude | size which the resin material provided in each of the adjacent terminal row member 2 does not mutually influence in the case of insert molding performed after that.
In addition, the strip | belt-shaped thing before cut | disconnecting in formation of the terminal row | line | column member 2 is called the metal strip | belt material 1, Moreover, the terminal row | line member 2 and the connection member 3 which were formed by cut | disconnecting the metal strip | belt material 1 A belt-like member 4 with terminal rows is defined as a belt-like member 4 with a terminal row.

  Thereby, it becomes unnecessary to cut and remove the terminal portions 1a formed on the metal strip 1, and the terminal portions 1a can be used without any loss, so that an increase in manufacturing cost due to a decrease in material yield is effectively prevented. can do. Here, the moving length of the strip-like member 4 with terminal rows can be made longer than the feeding length of the metal strip 1 by the distance d.

  Here, from the viewpoint of manufacturing efficiency, the terminal array member 2 cut and formed from the metal strip 1 is connected to the connecting member 3 immediately after the cutting and while maintaining the posture at the time of cutting. Of course, it is also preferable from the viewpoint of product quality resulting from the accuracy of their connection.

Therefore, in the present invention, the connecting member 3a before the terminal row member 2 is connected is fed to the cutting portion 10 for cutting the metal strip 1 in a progressive die or the like. The terminal row member 2 formed is sequentially connected to the connecting member 3 at a position R on the front side in the feed direction A of the cutting portion 10.
In this way, the connecting member 3b and the terminal row member 2 connected to each other are moved in parallel with the feeding direction A of the metal strip 1 as indicated by an arrow B in FIG.

  According to this, the terminal row member 2 formed from the metal strip 1 can be cut immediately after the formation without causing a large shift in the posture at the time of cutting (position and direction in the left-right direction). 10 is connected to the connecting member 3 at a position R adjacent to the front side in the feed direction A, so that the connection can be smoothly performed and the production efficiency can be improved. 2 and the connection member 3 are connected with high accuracy, and the quality can be improved.

  From the viewpoint of improving the production efficiency and quality, the moving direction B of the connecting member 3b and the terminal array member 2 connected to each other is the same as the feeding direction A of the metal strip 1 in a plan view shown in FIG. On the other hand, it is preferable to arrange them in line with the feeding direction A so that there is no left-right displacement.

Here, the connection between the terminal row member 2 and the connecting member 3 can be performed by various methods such as welding and use of an adhesive, for example. It is easy to do.
In such a connecting step, for example, as shown in the II-II cross-sectional view of FIG. 2 (a), first, the upper die 11 is lowered toward the lower die 12, and thereby shown in FIG. 2 (b). Thus, the metal strip 1 is positioned by the positioning rod 13 protruding from the upper mold 11 together with the connecting member 3a sent from the left side of the drawing. Thereafter, the upper die 11 is further lowered, and the pressing portion 14 of the upper die 11 is pressed against both the overlapping connecting member 3 and terminal row member 2 as shown in FIG. The concave portion 5 is formed in the concave portion 5, and the connecting member 3 and the terminal row member 2 are connected to each other by frictional engagement between the concave portions 5. In addition, although it replaces with such a recessed part 5 here and illustration is abbreviate | omitted, it can also carry out interference fit joining by providing the hole part which penetrates both members. Alternatively, for example, various mechanical connections such as bending bonding, press-fit bonding, and the like can be used. For this connection, a fastening member such as a rivet or a shaft can be used.

In addition, in embodiment of illustration, as shown in FIG. 1, each of a pair of strip | belt-shaped connection member 3a is sent toward the feed direction front side of the cutting part 10 from each of the both sides which separated the metal strip 1. The band-shaped connecting member 3a is connected to the terminal row member 2 at the front side position R of the cutting portion 10, and at the same time, as shown in FIG. Then, it is cut into a predetermined length and used for mutual connection of adjacent terminal row members 2. It is preferable to form positioning holes in the belt-like connecting member 3a in advance at a predetermined interval in the longitudinal direction. In this case, the connection length is determined by the positioning hole pitch provided in the belt-like connecting member 3a. Can be.
It is preferable that the feeding length of the strip-shaped connecting member 3a is, for example, larger than the feeding length of the metal strip 1 and smaller than the moving length of the connecting member 3b and the terminal row member 2 connected to each other.

  The strip-shaped member 4 with terminal rows thus formed is then subjected to insert molding for sealing the terminal rows 4a formed of the predetermined number of terminal portions 1a with a resin material, and on the resin material. A support fitting is arranged. In addition, it is also possible to make this support metal fitting the connection member 3a.

FIG. 3 is a perspective view illustrating the band-like member 4 with a terminal row that can be manufactured by the manufacturing method described above in a state before the insert molding is performed.
The strip-like member 4 with terminal rows shown in the figure is arranged between the terminal row members 2 arranged in the longitudinal direction at predetermined intervals and the adjacent terminal row members 2, and these terminal rows are arranged. It has the connection member 3b which connects the members 2 mutually. Therefore, in this strip-shaped member 4 with a terminal row | line | column, the terminal row | line member 2 and the connection member 3b are arrange | positioned alternately. The terminal portion 1a of the terminal row member 2 may be plated as necessary.

In addition, it is preferable that the terminal row member 2 and the connecting member 3b are made of the same kind of metal material from the viewpoint that they can be reused after disposal. The material of these members can be, for example, phosphor bronze, SPC, SUS, brass or the like generally used for connectors or the like, and other metal materials can also be used.
This strip-shaped member 4 with a terminal row is insert-molded, and although not shown, the terminal row 4a including a plurality of terminal portions 1a can be sealed with a resin material.

  As described above, according to such a method for manufacturing a band member with a terminal row, the highest accuracy is achieved in various steps in manufacturing the band member with a terminal row, and it is continuous within the same mold. It is clear that cutting and recombination can be performed in this manner, and therefore, unlike the conventional carrier method as described in Patent Document 1, all the problems described here can be solved.

  The manufacturing method described above may be incorporated into a press die for forming the terminal portion 1a of the metal strip 1. In this case, the mold is provided in the middle of the belt material conveying means for intermittently feeding the metal band material 1 along its longitudinal direction, and cuts the metal band material 1 to a predetermined length.
