３により固定している。(b) Prior art and problems The conventional connector plug structure is, as shown in Fig. 2, usually punched from a phosphor bronze strip by a continuous press with a multi-step progressive die, and then gold or other prescribed plating is applied. As shown in FIG. 1, the contact portions of the plug terminals 2 are formed in parallel with each other, and the lead portions of the plug terminals 2 are formed in parallel with each other. It is fixed by an insulator 3 made of resin so as to project in the opposite direction.

タを組み上げて完成するいわゆるインサートモールド法
で形成されている。In such a connector plug, a jack terminal or a plug terminal and a mold insulator are separately manufactured, and the terminal is inserted and fixed to the mold insulator by a manual or automatic machine, or the terminal is molded when molding the insulator. It is formed by a so-called insert molding method in which it is placed in a predetermined position in a mold cavity and molded, and at the same time, a connector is assembled and completed.

ド型の要部のみの断面図により説明する。However, in the case of the connector plug 1 having a structure in which the shape of the terminal 2 cannot be inserted into the insulator 3 as shown in FIG. 1, the concert mold method is always adopted, and the insert mold method is used to obtain the concert mold method shown in FIG. A method of manufacturing the connector plug 1 will be described with reference to FIG. 3 which is a sectional view of only a main part of a mold attached to the injection molding machine.
まず前述のプラグ端子(2)を収容するモールド型(4)の溝
(6)と(7)とをガイドにして、プラグ端子(2)を正しく挿

る。First, the groove of the mold (4) that houses the plug terminal (2) described above.
Using (6) and (7) as guides, insert the plug terminal (2) correctly, then close the upper mold (5) to preheat the entire mold,
Next, the fluid synthetic resin molding material is used for the cavity (8).
A connector plug (1) is molded by injection-filling it into a solidified polymer and taking it out from the mold after cooling.
このインサートモールドによる成型法は、前述のような
絶縁体と端子とを後で組み立てる工数を要しない利点が
ある反面、第３図に示すように微細な端子をモールド型

一方端子(2)の根元の位置にモールド材料がバリとして
突出するのを防ぐため、モールド型４の当該角部９の寸
法精度を厳しく加工せねばならないという問題がある。This insert molding method has the advantage of not requiring the steps of assembling the insulator and the terminal later, but on the other hand, as shown in FIG. 3, a large number of fine terminals are correctly placed at predetermined positions of the mold. It takes a lot of time to place it,
On the other hand, in order to prevent the molding material from protruding at the base position of the terminal (2) as a burr, there is a problem that the dimensional accuracy of the corner portion 9 of the molding die 4 must be strictly processed.
また、この種の問題はインサートモールドに共通した問
題であって、端子２挿入に関しては当該端子２を連続的
に仮接続した後に切断するという改善法もあるがいかな

はモールド型の精度向上以外によい対策方法がないので
型製作費が高騰するという問題もある。Further, this kind of problem is a problem common to insert molding, and regarding insertion of the terminal 2, there is an improved method of disconnecting the terminal 2 after the terminal 2 is temporarily connected, but it is not a method that can be adopted at any time, The latter problem of burrs has a problem that the cost for producing the mold rises because there is no good countermeasure other than improving the precision of the mold.

A groove (10b) for preventing rotation of the terminal (2) is arranged on the lower end face to mold a first insulator (10) which becomes a part of the connector body, and each insertion of this insulator (10) By inserting the contact portion (2a) of the L-shaped terminal (2) into the hole (10a) and fitting the respective lead portions (2b) into the rotation preventing groove (10b), the opposing terminal (2) To form a temporary assembly (11) in which the lead portions of the two protrude in opposite directions.

る。In this temporary assembly (11), as shown in FIG. 4, a second mold is used as the remainder of the connector body to bury at least a portion fitted in the groove (10b) of the terminal (2) ( Fig. 4 shows that the terminal 2 is buried from the position where it exits the insertion hole (10a) to the part where it fits in the groove (10b). At the same time, the standoff (17a) (this standoff (17a) is A second insulator (17) that prevents deformation of the lead portion (2b) protruding from the connector body and has the tip joint surface of the lead portion (2b) flush with the mounting surface of the completed connector) Bond molding,
A connector is constructed in which the terminal (2) is fixed and the first insulator (10) and the second insulator (17) are integrated.
そして、第６図の要部断面図に示すような第２のモール
ド型(12),(13)を用意する。Then, the second molds (12), (13) as shown in the sectional view of the main part of FIG. 6 are prepared.

The first insulator with the temporary assembly (11) manufactured earlier as the core
The contact part (2a) of the terminal (2) by closing with (10)
The cavities (14) and (15) for accommodating the lead and the lead portion (2b) are formed, and the resin is injected only into the cavity (16) to form a part of the terminal (2), that is, the groove (10b). The part that is fitted in is buried, but the positioning of the temporary assembly (11) at this time is performed by the concave part (12a) of the mold (12) and the convex part (13a) of the mold (13).
The temporary assembly (11) itself is larger than the terminal (2) and is easier to handle, and inserts a small terminal part into the thin groove of the mold (13) as in insert molding. The delicate work of placing it is unnecessary.

体を有するコネクタプラグ(18)が完成する。Then, according to the usual injection molding method, the mold material is injected and filled into the mold cavity (16) to form a fourth mold.
As shown in the sectional view of the figure, a connector plug (18) having a connector body composed of two layers of first and second insulators (10) and (17) is completed by injection molding twice.
その結果、該絶縁体(10)を製作する第１のモールド型

い。As a result, the first mold for producing the insulator (10) may have burrs at the opening of the insertion hole (10a) of the insulator (10), but the insulator (10) alone. At this time, since the terminal 2 is not yet inserted, the plug terminal does not interfere with the work to prevent the deburring work, and the burr can be easily mechanically removed, so that it is not necessary to make it highly accurate.
また、コネクタプラグ寸法としてもっとも重要な各端子

第二モールドの型の精度も厳しく要求されることはなく
モールド作業も容易であるから、コネクタプラグ(18)の
要求精度を満足しつつ第二回目の射出成形用モールド型
の型製作費及びモールド作業費も共に削減出来る。Also, the relative position between the terminals, which is the most important dimension of the connector plug, has already been shown in the temporary assembly (11).
Since the precision of the mold of the second mold is not strictly required and the molding work is easy, the mold manufacturing cost of the second injection molding mold and the mold while satisfying the required accuracy of the connector plug (18). Both work costs can be reduced.

After all, they are integrally formed, but they are not always necessary and may be separately located. In short, the first insulator
(10) is used for temporary assembly, and the second insulator (17) is used for terminal fixing with separated functions.
尚、以上の実施例はコネクタプラグの製作の場合につい
てであったが、コネクタジヤックの場合にも同様に適用
出来るということは自明である。It should be noted that, although the above-described embodiment is for the case of manufacturing the connector plug, it is obvious that the same can be applied to the case of the connector jack.

Since there is no need for high-precision machining, the cost of mold production is low, and the manufacturing cost of the connector can be significantly reduced, and at the same time, it is possible to provide robust and high-quality products with high precision.
