BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a comb-teeth-shaped terminal member used for a connector in which the number of terminals arranged on the external side is larger than the number of terminals arranged on the contact side, and a method of assembling a connector using the same. In particular, by assembling the connector by reducing the number and types of comb-teeth-shaped terminal members used, the comb-teeth-shaped terminal member material and the number of assembling steps are reduced to improve the productivity. The present invention relates to a terminal member and a method of assembling a connector using the terminal member.

In the field of electronic devices in recent years, with the increase in the amount of information to be exchanged, connectors for connecting respective devices are becoming smaller and the terminal density is increasing. In this case, it may be necessary to increase the number of arrays on the side of the external connection terminals to be mounted on the circuit board of the connector from the number of arrays on the side of the contact in consideration of the mounting surface. Since tooth-shaped terminal members are used, rationalization thereof is desired.

Although it can be fixed to the insulator 3 by being press-fitted into the rectangular through hole 3b formed in alignment with the inner portion of the inner surface of the peripheral wall 3a of the bottom surface of the bottom wall, it is offset in the opposite direction when fixing the terminal. The bent external connection terminals 2b are adjacent to each other.

Therefore, when viewed in a cross section orthogonal to the longitudinal direction (3-
As shown in 2), the external connection terminals 2b of the jack terminal 2 protruding from the jack insulator 3 are arranged in four rows. On the other hand, a plug connector (hereinafter referred to as a plug) 5 connected to the jack 1 has a straight plug contact 6a whose one end is in contact with the jack contact 2a as shown in (3-3).

Therefore, the plug 5 shown in FIG. 3 can be constructed by using two comb tooth-shaped terminal members 6'and 7 '.

[0013]

In the conventional connector assembling method using the comb-teeth-shaped terminal member, the comb-teeth-shaped terminal member corresponding to the offset bending direction of the external connection terminal portion with respect to the contact region must be used. Therefore, the number and types of the terminal members used are increased, and the terminals connected to the respective terminal members have a terminal pitch of 2 as a connector.
There is a problem that it is not possible to expect productivity improvement in terms of cost, such as man-hours for forming comb-teeth-shaped terminal members and material costs, because it is doubled, and insulation due to the large number of terminal members There was a problem that the number of press-fitting steps to the body hindered improvement in productivity.

[0017]

When the comb-teeth-shaped terminal member is formed so that the external connection terminals that are offset and bent in the opposite direction or on one side are located alternately with respect to the contact areas arranged in a row, two contact areas are formed for the contact areas in a row. The terminals of the connector in which the external connection terminals of the row are located can be supplied by a single comb-shaped terminal member.

In the present invention, the external connection terminal portions of the terminals connected in a comb-like shape to the connecting material are bent in a rectangular shape so as to alternately inflate in opposite directions or every other terminal, and then the contacts on the free end side are aligned. The connecting member is press-fitted into the insulator from the side, and the connecting member is cut off in the rectangular-shaped external connection terminal region.

Therefore, it is possible to supply a plurality of terminals in which the contact portions arranged in one row are arranged in one row and the external connection terminal portions are arranged in two rows by one comb-teeth-shaped terminal member, resulting in the number of contact arrangements. The required connector can be formed by a number of comb-teeth-shaped terminal members corresponding to the above.
