It was technically difficult to attach, and even if it could be attached, it was difficult to obtain mechanical strength.

The present invention has been made in view of the above problems, and an object thereof is to provide a roller with a thickness a of a wall portion between terminal mounting holes of an insulating case and a lowermost terminal mounting. An object of the present invention is to provide a board mounting structure for an electrical connector, which enables the metal member to be mounted even when the thickness b between the hole and the bottom surface of the insulating case is thin, thereby improving the mounting strength.

[0006]

[Means for Solving the Problems]

 To achieve the above object, the present invention provides a plurality of fixing pin bodies on the bottom surface of an insulating case of an electrical connector, and these fixing pin bodies are attached to a pin body integrally formed with the insulating case. It is characterized in that the member is fitted and fixed, the fixing pin hole is formed on the board side, and the fixing pin body is inserted into the fixing pin hole to solder the metal member to the board side.

[0007]

[Action]

 With this configuration, even if the thickness a of the wall portion between the terminal mounting holes of the insulating case and the thickness b of the wall portion between the lowest terminal mounting hole and the bottom surface of the insulating case are thin, the metal member can be attached. As a result, the mounting strength can be improved.

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. 1 is a plan view of an electric connector having a base plate mounting structure according to the present invention, FIG. 2 is a front view thereof, FIG. 3 is a bottom view thereof, and FIG. 4 is a side view thereof.

The electrical connector 1 is provided with an insulating case 2, which is a rectangular block body. The front part 2a of the insulating case 2 is formed with a large number of terminal mounting holes 3 extending from the front part 2a to the back part 2b at equal pitches, and terminals 4 are mounted in these terminal mounting holes 3. The legs 5 of the terminals 4 project rearward, and these legs 5 are bent at a right angle.

A plurality of polar key mounting protrusions 6 are formed on the bottom surface 2c of the insulating case 2 at the front side at predetermined intervals in the left-right direction, and are fixed to the rear side of the bottom surface 2c. A plurality of pin bodies 7 and positioning pin bodies 8 are provided.

That is, the fixed pin bodies 7 are provided on the rear side of the bottom surface portion 2c at a predetermined pitch interval, and the positioning pin bodies 8 are positioned between these fixed pin bodies 7 at a predetermined pitch. The fixed pin body 7 and the positioning pin body 8 are linearly arranged at intervals.

As shown in FIG. 9, the fixed pin body 7 includes a resin-made pin body 10 integrally formed with the insulating case 2 and a metal member 11. The pin body 10 has a head portion 10a. The metal member 11 is a cylindrical body having a split groove 11a in a part of its circumference as shown in FIG. Then, the fixed pin body 7 is configured by fitting the metal member 11 onto the pin body 10 and fitting the metal member 11 by elasticity. Further, an alignment member 13 is attached to the leg portion 5 of the terminal 4 of the electric connector 1 configured as described above.

Further, as shown in FIG. 11, a plurality of fixing pin holes 15 are formed along the edge portion 14a of the substrate 14 at predetermined intervals, and these fixing pin holes 15 are formed by metal seats. It is formed on the body 16 and the metal seat 16 is fitted to the substrate 14. Further, a plurality of positioning holes 17 are formed between the fixing pin holes 15 at predetermined intervals. A large number of through holes 18 are formed in the substrate 14.

Next, mounting of the electrical connector 1 on the substrate 14 will be described. The legs 5 of the terminals 4 of the electric connector 1 are inserted into the through holes 18, the positioning pin body 8 is inserted into the positioning hole 17, and the fixing pin body 7 is inserted into the fixing pin hole 15. 2c is brought into contact with the mounting surface of the substrate 14. Then, the leg portion 5 of the terminal 4 is soldered to the through hole 18 and the metal member 11 of the fixed pin body 7 is soldered to the metal seat body 16.

According to the above-described embodiment, the fixing pin body 7 of the bottom surface portion 2c of the insulating case 2 is fitted to the electric connector 1, and the metal member 11 is fitted to the pin body 10 formed integrally with the insulating case 2 to be fixed. In this case, by forming a metal fixing pin hole 15 on the substrate 14 side, inserting the fixing pin body 7 into the fixing pin hole 15 and soldering the metal member 11 to the fixing pin hole 15, Even if the thickness a of the wall portion between the two terminal mounting holes 3 and the thickness b of the wall portion between the lowest terminal mounting hole 3 and the bottom surface 2c of the insulating case 2 are thin, the metal member 11 cannot be mounted. It is possible to improve the mounting strength (mechanical strength).
