Will be described. The terminals 60 are attached by being pressed into the respective grooves 32 from the back surface 33 of the connector body 30. In this example, as shown in FIG. 1, 14 terminals 60 are attached to the connector body 30. The portions of the terminals 60 exposed on the inner surface of the rectangular tubular portion 31 function as contacts that come into contact with the contacts of the mating connector. The fourteen terminals 60 projecting from the back surface 33 of the connector body 30 are bent along the back surface 33 toward the bottom surface (mounting surface) of the connector body 30. 7 located on the inner circumferential top side
The terminals 60 and the seven terminals 60 located on the lower surface form a row, and are bent so as to form two rows on the mounting surface. It should be noted that the terminals 60 are bent in such a manner that seven of the terminals 60
Are positioned at the tooth bottom 36b, respectively, and the seven rows in the farthest row are positioned at the tooth tips 36a of the terminal alignment portion 35, respectively. It is protruding. With the terminal 60 thus positioned,
The base 40 is attached to the connector body 30. The mounting of the base 40 is performed by pushing the concave grooves 44 formed on the inner surfaces of the two leg portions 43 in such a manner as to match the two locking portions 38 of the connector body 30, thereby providing the two leg portions 43. The locking projection 38a is engaged with the locking window 45, and is locked and fixed. At this time, the teeth 42 of the base 40 and the teeth 36 of the terminal aligning portion 35 mesh with each other, thereby forming the tip 36 of the terminal aligning portion 35.

The terminals 60 are sandwiched in two rows between the tooth bottom 36b and the tip 42a of the base 40. As described above, in this example, the terminals 60 are positioned and aligned with high precision by being sandwiched between the teeth 36 of the terminal aligning portion 35 and the teeth 42 of the base 40, as shown in FIG. In order to align the plurality of terminals 12 like the conventional connector 17 shown in the drawing, it is not necessary to perform a troublesome operation of inserting the terminals 12 into the positioning holes 14 of the terminal alignment plate 13. A structure in which the terminal 60 is pushed by the tooth tip 42a of the base 40 and a dimension in the arrangement direction of the teeth 36 of the tooth bottom 36b of the terminal alignment part 35 and a structure in which the terminal 60 is pushed by the tooth tip 36a of the terminal alignment part 35. By setting the dimension of the teeth 42 on the bottom 42b of the base 40 in the arrangement direction slightly smaller than the size (width) of the terminal 60 to be pushed in,
The terminal 60 can be pressed from the direction, and the terminal 60 can be positioned with higher accuracy. As shown in FIG. 1, the cover 50 covers the upper surface of the connector body 30, the outer peripheral portion of the rectangular tubular portion 31, both side surfaces on the back surface 33 side, and the terminal 60 from the back surface 33 to the terminal alignment portion 35.

The cover 50 is formed by performing a required bending process on a single metal plate having a required shape, and has a lower end provided with a terminal for ground connection and for reinforcing the mounting strength of the connector 20 to the mating substrate. 51 are provided. In the above-described example, it has been described that the discrete terminals 60 are sandwiched between the terminal alignment portion 35 and the base 40. However, for example, as shown in FIG. When the terminals are sandwiched between the terminal alignment portion 35 and the base 40 in a state where the tips are connected to each other, and the carrier 61 is cut and removed after being sandwiched, the terminals 60 are positioned with high accuracy by the carrier 61. Therefore, the terminals 60 can be easily and collectively incorporated into the terminal alignment section 35, and the workability can be greatly improved. In FIG. 4, a broken line indicates a cut portion of the carrier 61, and 62 indicates a pilot hole provided in the carrier 61. Further, in the above-described example, the description has been given of the connector of the type in which the terminal 60 protrudes from the bottom surface (mounting surface) of the connector 20 and is inserted into the through hole of the counterpart board and soldered. Can employ the same configuration. As described above, according to the present invention, a plurality of terminals are provided with the respective tooth tips of the terminal alignment portion of the connector body and the base, each of which has a toothed shape of a rack whose opposing surfaces mesh with each other. It is a structure that is sandwiched between the roots of the teeth and aligned in two rows with high precision, so compared to a structure in which each terminal is inserted into a positioning hole and aligned like a conventional connector, A connector that is easy to assemble and that can be manufactured at a lower cost can be obtained. Because of the structure in which the terminals are sandwiched and aligned as described above, it is possible to adopt a method in which a plurality of terminals are incorporated in a state where their ends are connected and integrated by a carrier. By adopting the method, a plurality of terminals can be assembled with high accuracy and collectively, so that the workability is further improved.
