る。 That is, what is shown in FIG. 4 is a developed view of the contact portion 4, in which four elastic tongues 42 are arranged to protrude in a comb shape from the upper end of the ring portion 41, and the ring portion 41 is formed into a cylindrical shape. When the contact portion 4 is formed by rolling, each elastic tongue piece 42 faces each other. Each opposing elastic tongue piece 42
are bent so that the mutual spacing gradually narrows as it approaches the tip direction, and the shapes shown in Fig. 3 a, b,
A contact portion 4 shown in c is formed, and a mating pin contact 3 (indicated by a two-dot chain line) is inserted into the contact portion 4 through a terminal introduction port 43 and brought into contact with the elastic tongue piece 42.

In the conventional example described above, four elastic tongues 42 are shown, but in order to obtain a stable contact state,
Furthermore, it is necessary to increase the number of sheets and increase the number of contacts.
However, in the conventional structure, increasing the number of contacts inevitably increases the radial dimension of the contact portion 4 and also increases the insertion force, making it unsuitable for use in a multi-core high-density connector.
それ故に、本考案の目的は弾性舌片の枚数を増

クトを提供することである。 Therefore, the purpose of the present invention is to create a multi-contact point that can be miniaturized and maintain a stable contact state without increasing the insertion force, even when attempting to create multiple contacts by increasing the number of elastic tongues. The purpose is to provide socket contact.

The multi-contact socket contact according to the present invention has a plurality of contact parts arranged in the contact insertion/removal direction, and the contact part includes an elastic tongue piece that contacts a mating contact and a cylindrical part continuous with the elastic tongue piece. The elastic tongues of the contact portions are extended from one end side into the interior of the adjacent contact portions, and the cylindrical portion is continuous with the external connection terminal portion and is integrally molded from an elastic conductive material.
With this configuration, it is possible to suppress the increase in the dimensions of the contact in the radial and axial directions, even though it is possible to increase the number of contact points by using a contact having a larger number of elastic tongues than in the past. I can do it. Further, by arranging the contact portions in series in the fitting direction, the mating pin contacts sequentially abut and slide against the elastic tongues during insertion. Therefore,
By dispersing the insertion force, a multi-contact socket contact can be obtained in which the insertion force is reduced, especially at the initial stage of insertion, and the insertion and removal life is improved.

After bending the connecting piece 16 to be approximately perpendicular to the base 15 along the broken line m, which is the continuous point between the connecting piece 16 and the first ring part 17, Along the broken line n, which is the first
The ring portion 17 is bent approximately at right angles to the connecting piece 16 in the direction opposite to the base 15 side. Next, the first ring part 17 is folded back in an arc toward the base 15 side, and rolled into a cylindrical shape with a diameter of approximately 1/3 of the length L1 of the first ring part to form the terminal introduction port 20. The first contact portion 12 is formed by bending the four first elastic tongues 13 such that the distance between them gradually narrows as they approach the external connection terminal portion 11 direction. Next, the diameter of the second ring part 18 is approximately 1/3 of the length dimension (=L 2 ) that is the sum of the width of the second ring part 18 and the width of the base 15, and The base 1 surrounds the 13 portion of the elastic tongue piece 12.
Fold back on the 5th side to form a cylindrical shape. Furthermore, as the second elastic tongue piece 19 approaches the external connection terminal section 11, the mutual interval between the tongue pieces 19 is gradually narrowed.
A contact portion 14 is formed. Incidentally, during the above bending process, the portion of the base portion 15 from the first contact portion 12 to the second contact portion 14 is also bent into the same arc as the second ring portion 18 .

れる。 As mentioned above, the contact 1 of the present invention is
Contact portion 1 with elastic tongues 13 and 19 arranged in series
Since the ring portions 17 and 18 are distributed over two ring portions 17 and 18 to provide multiple contact points,
That is, since the radial dimension of the contact parts 12 and 14 can be reduced, and the fitting part 21 is formed by making the first elastic tongue piece 13 face into the second contact part 14, the contact 1 can be made smaller in the axial direction. It is also shortened for

る。 Furthermore, by arranging the contact portions 12 and 14 in series with respect to the mating direction, the mating pin contact 3
(indicated by a two-dot chain line), when inserted, as in the conventional example,
Unlike the case in which the elastic tongue pieces 42 are brought into contact with each other at once, as the insertion progresses, the elastic tongue pieces 13 and 19 are sequentially brought into contact and slid. Therefore, the insertion force is applied to each contact portion 12, 14.
As a result, the insertion force is reduced. Further, after insertion, the pin contact 3 is held in contact with the elastic tongues 13 and 19 at a plurality of locations (two locations in the embodiment) in the axial direction, so that stable contact can be obtained even against external forces such as vibrations. In addition, since the structure allows a larger number of elastic tongues 13 and 19 to be provided than in the past, it is also possible to reduce the contact force that one elastic tongue takes on, and therefore, it is possible to reduce the contact force that a single elastic tongue has to bear. Contacts 1 with improved lifespans can be obtained.
尚、実施例では、接触部を２個直列に設けたも
のについて述べたが、本考案の技術思想にもとず
いて、２個以上設けることも可能であることは云
うまでもなく、又弾性舌片の枚数についても本実
施例に限定されるものではない。 In the embodiment, two contact parts are provided in series, but it goes without saying that it is also possible to provide two or more contact parts based on the technical idea of the present invention. The number of tongue pieces is also not limited to this embodiment.

As is clear from the above explanation, the present invention is suitable for multi-core high-density connectors because it is compact and the insertion force can be reduced even though it has a larger number of elastic tongues than the conventional one to achieve multiple contacts. Furthermore, by holding the mating pin contacts in contact with each other at a plurality of locations along the fitting direction, a multi-contact socket contact that is stable against external forces such as vibrations and suitable for multiple insertions and removals can be obtained.
