Description

[Detailed description of the invention] [Industrial application field] The present invention relates to the structure of a component mounting socket.

[Prior Art] Conventionally, this type of socket has a plurality of contact pins 11 arranged at regular intervals corresponding to the intervals of through holes 10 of a printed circuit board 9, as shown in FIG. 3, in a socket case 12. It had a structure in which it was connected and fixed to the contact part 13.

In addition to this, there is also a single socket in which each contact pin is connected and fixed to one socket case.

[Problems to be Solved] In recent years, the shapes of parts have diversified, and the spacing between the connecting pins 6 of the parts has also tended to diversify accordingly.

In the conventional socket described above, contact pin 1
1 is fixedly connected to the socket case 12, and the intervals between the contact portions 13 to which the connecting pins 6 of the component 5 are connected are also fixed at regular intervals. Therefore, considering versatility, the probe 2. When using a printed circuit board inspection jig that is arranged at regular intervals of 54 mm and a package inspection jig after component mounting, component pin positions that are outside the integral multiple of 2.54 mm will not be detected. There is a drawback that defective products may be mixed in. In addition, in order to achieve 100% detection, it is necessary to create an inspection jig for each type of printed circuit board 9, which requires time and money to manufacture the jig, and the inspection of the printed circuit board 9 is not performed during the manufacturing time. This has the disadvantage that it can seriously disrupt the schedule.

[Means for solving interlayer points] The present invention has been made to solve the above-mentioned conventional problems, and as a means for solving the problem, a socket case for connecting connection pins of mounted components and a through-hole on a printed circuit board are provided. In the socket, the socket case and the contact pin are connected by a flexible member that is formed of a spring-like member and follows the movement of the socket case, and the contact pin is engaged with the through hole. The present invention provides a socket characterized by being provided with a stopper for locking.

[Example] Next, an example of the present invention will be described with reference to the drawings.

FIG. 1 is a partial vertical cross-sectional view of a socket according to an embodiment of the present invention, and FIG. 2 is a vertical cross-sectional view showing a state in which the socket of FIG. 1 is mounted.

Socket 1 includes socket case 2 and contact pin 3.
and a flexible member 4 provided between the contact pin 3 and the socket case 2.

The socket case 2 has a contact portion 7 for inserting and connecting the connecting pin 6 of the component 5 therein. The socket case 2 is made of an insulating material and protects and supports the contact portion 7 therein.

The contact pin 3 is formed of a rod-shaped conductive member, and has a stopper 8 formed at its upper end. Stopper 8
is formed wide at the upper end of the contact pin 3, and has the function of locking the contact pin 3 to the printed circuit board 9, as shown in FIG.

The flexible member 4 is a conductive spring-like member, and its upper end is connected to the contact portion 7 of the socket case 2, and its lower end is connected to the stopper 8 of the contact pin 3. Thereby, the flexibility of the socket case 2 is maintained.

Next, the implementation and operation of the socket 1 according to this embodiment will be explained.

As shown in FIG. 2, the contact pins 3 of the socket 1 are inserted into through holes 10 formed in the printed circuit board 9 at intervals of an integral multiple of 2.54 mm. At this time, the contact pin 3 is locked to the printed circuit board 9 via the stopper 8.

Part 5 where the distance between the connecting pins 6 is not an integral multiple of 2.54 mm
, move the socket case 2 toward the connecting pin 6 of the component 5. At this time, since the flexible member 4 follows the movement of the socket case 2, the socket case 2 can be connected to the connection pin 6. By making the above connections to all the connection pins 6, the connection of the component 5 to the socket 1 is completed.

[Effects of the Invention] As explained above, the present invention connects a socket case and a contact pin having a locking stopper with a flexible member, so that through-holes are formed on a printed circuit board by adjusting the spacing between connecting pins of components to be mounted. Regardless, they can be provided at intervals that are integral multiples of 2.54mm, and as a result, there is no need to create inspection jigs for each type of printed circuit board, and the effect is that 100% inspection can be performed at low cost and in a short period of time. .
