Description

[Detailed description of the invention] The present invention enables the connector body made of molded resin to be used as both a horizontal connector and a vertical connector in a connector equipped with a large number of terminals, such as a 21-pin multi-connector. The present invention relates to a connector structure in which a connector main body and a terminal holder for preventing deformation of a terminal group are formed as a common mold.

Referring to the drawings, 1 is the socket body of the connector, 2 is the socket insertion hole, 3 is the terminal row A, which has 10 terminal insertion holes, and 4 is the terminal row B, which has 11 terminal insertion holes. It consists of individuals. 5 is a terminal, which is a terminal group consisting of a terminal row A and a terminal row B, which is a total of 21 terminals, and the illustrated example represents a 21-pin multi-connector. 6 is a tongue piece integrally molded with the socket main body 1, and 7 is a mounting hole. Reference numeral 8 denotes a terminal holder, and an insertion hole 9 is formed in the surface 10 at a position corresponding to the terminal group so that the terminals of the terminal group can be held therethrough.
has a tapered opening to facilitate insertion of the terminal. Elastic pieces 11, 11 are provided at both ends of the same surface 10 and are substantially perpendicular to the same surface, and engaging portions 12, 12 are provided at the ends of the elastic pieces 11, 11, respectively.

On the back side of the socket body part 1 of the connector,
Engaging portions 13, 13 that elastically engage with the engaging portions 12, 12 are arranged symmetrically with respect to the center line of the terminal rows A and B.

Note that one engaging portion 13 may be provided on the center line, and the material of the socket body and terminal holder is ABS resin, glass-filled nylon, or heat-resistant engineering plastic such as PBT (polybutylene terephthalate). .

Reference numeral 14 designates a protrusion that prevents the terminal group from being inserted into a printed circuit board (not shown).

As a result, even if the terminal rows A and B are asymmetrical due to their number or arrangement,
For example, even if one terminal row crosses another terminal row and is bent at a substantially right angle with the other terminal row, or vice versa, the other terminal row crosses one terminal row and bends the same terminal row together with the other terminal row. Even if the socket body and the terminal holder of the connector are bent at substantially right angles along with the row, there is no need to change the molding of either the socket body or the terminal holder, so that the structure can be highly effective in mass production. Further, according to the above configuration, the above-mentioned connector can be directly attached to the main printed wiring board.

[Brief explanation of the drawing]

Fig. 1 is a top view showing the front surface of the 21-pin multi-connector, Fig. 2 is a bottom view showing the back side of the 21-pin multi-connector according to the present invention, and Fig. 3 is partially omitted from Fig. 2 A-A 4 is a plan view of the terminal holder of the present invention, and FIG. 5 is a sectional view taken along line BB in FIG. 4. 1 is a main body, 8 is a terminal holder, 11 is an elastic piece,
12 is an engaging portion; 12 is an engaging portion; and 14 is a protrusion.

Claims (1)

[Scope of utility model registration request] In a connector socket having a plurality of terminal rows and a large number of terminals per row, one terminal row is bent at a substantially right angle with the other terminal row across the other terminal row. A plurality of rows of bent terminals are held through the insertion holes of a terminal holder, respectively, and the engaging portions of the elastic pieces at both ends of the surface of the holder having the insertion holes and substantially perpendicular to the same surface are connected to the connector. A connector characterized in that the connector is elastically engaged with an engaging part located on the back surface of the socket main body and arranged symmetrically with respect to the center line of the plurality of terminal rows.
