Abstract

PURPOSE:To insert a number of connector pins into through-holes simultaneously by a method wherein a jig in which pins are arranged in the same arrangement as the arrangement of the terminals of a module is prepared and the pins are inserted into the connector pins and the connector pins are inserted into through- holes as they are. CONSTITUTION:Holes are drilled in the jig plate 9 of a jig 12 in the same arrangement as the arrangement of the terminals of a module and jig pins 10 penetrate the holes. The protruding length of the pin 10 is defined by a back plate 11 and the pins 10 are fixed. By inserting the pin 10 of the jig 12 like this into the terminal holding part 7 of the connector pin 5 of a connector 2, the center axis of the pin 5 is made to agree with the center axis of the through-hole of a board. With this constitution, a number of the pins 5 can be inserted into the through-holes of the board simultaneously without causing buckling of the inserted part 6 of the pin 5. Further, if the jig 12 is removed from the connector 2 and the terminals of the module are inserted into the terminal holding parts 7 after the inserted parts 6 are soldered to the plated parts of the through-holes, the module are electrically connected to the board through the connector 2.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a method for inserting a connector into a board, and in particular,
Connector insertion into a board suitable for simultaneously inserting all of the many pins of this connector into through-holes on two boards when installing an electrical element (so-called module) having a large number of connection terminals on a board using a connector. It is about the method.

[Conventional technology]

In the field of large electronic computers, various components have been mounted in high density, and mounting methods using modules equipped with elements have become mainstream. In order to facilitate maintenance of the module, when installing the module to the printed circuit board, first attach the connector to the printed circuit board, connect the two electrically by soldering, and then attach the module to this connector. I'm trying to get it right.

In this case, in order to simultaneously insert all of the connector's many high-density connecting pins into the through holes provided on the board, it is necessary to match the positions of the connector's connecting pins and the through holes on the board. need to match. As for the method for this.

There is a method described in Japanese Unexamined Patent Publication No. 58-66393.

This method is shown in FIGS. 2 and 3.

A comb-shaped guide 18 that matches the positions of horizontal rows of a large number of through holes (not shown) two-dimensionally provided on the substrate 3.
and comb-shaped guides 19 that match the positions of the vertical rows are separately prepared. Then, the horizontal comb-shaped guide 18 is inserted into the board insertion portion 6 of the connector bin of the connector 2 from the horizontal direction, and the vertical comb-shaped guide 19 is inserted into the board insertion part 6 of the connector bin from the vertical direction. Insert in a direction perpendicular to the direction of the insertion section 6. Thereby, the position of the board insertion part 6 of the connector pin is matched with the position of the through hole of the board 3, and then the board insertion part 6 of the connector pin is inserted into the through hole of the board 3. Thereafter, the comb-shaped guides 18 and 19 are extracted.

[Problem that the invention seeks to solve]

In the above conventional technology, the board insertion part 6 of the connector pin is inserted into the board 3.
After inserting the comb-shaped guides 18 and 19 into the through holes of
No consideration was given to the need for space to extract the material. i.e. 2 usually a large number of connectors 1
are arranged adjacent to each other on the substrate 3, the space required for extracting the comb-shaped guides 18 and 19 cannot be obtained.

There was a problem.

An object of the present invention is to attach all the connector pins of the connectors to the through-holes of the board at the same time without requiring any space between adjacent connectors for attaching and detaching jigs when attaching the connectors to the board. An object of the present invention is to provide a method for inserting a connector into a board that can be inserted into the board.

[Means for solving problems]

The above purpose is to insert a jig with pins in exactly the same arrangement as the module's terminals into the connector pins into which the module's terminals are inserted, and align the center axis of the connector pin with the center axis of the through hole in the board. This is accomplished by aligning, inserting the connector pin into the through hole in the board, and then pulling the jig out of the connector pin.

[Effect]

Fig. 4 is a perspective view showing how the module is attached to the board via the connector, and Fig. 5 is a partial cross-sectional view showing the relative position of the through holes in the board, the connector pins of the connector, and the terminals of the module, and the structure of the connector. It is.

In FIG. 4, the connector 2 electrically connects the board 3 and the module 1.

A connector pin (not shown) of the connector 2 is inserted into a through hole (not shown) of the substrate 3, and the plated portion of the through hole and the connector pin are electrically connected by soldering. Then, insert the terminal 8 of the module 1 into the connector pin of the connector 2, and connect the terminal 8 of the module 1 to the board 3 via the connector 2.
and the module 1 are electrically connected.

Therefore, module 1 is removable.

In FIG. 5, the connector 2 is composed of a mold 4 and connector pins 5, and the mold 4 has a through hole 21 in the board 3 at a position corresponding to the through hole 21 in the board 3.

Holes 22 are provided for receiving connector pins 5. The connector pin 5 is made of conductive metal material.

The upper terminal holding part 7 is adapted to hold the terminal 8 of the inserted module 1 by spring force, and the lower board insertion part 6 is inserted into the through hole 21 of the board 3 (not shown). It is designed to be soldered to the plated part.

Further, the position of the terminal 8 of the module 1 corresponds to the position of the through hole 21 of the board 3, and the position of the terminal 8 of the module 1 corresponds to the position of the through hole 21 of the board 3.
The central axis of the connector 2, the central axis of the hole 22 of the connector 2, and the central axis of the through hole 21 of the board 3 coincide with each other.

Even in this case, the connector pin 5 is connected to the mold 4.
Since the connector pin 5 is simply inserted into the hole 22 and is not fixed, normally the center axis of the connector pin 5 does not coincide with the center axis of the through hole 21 and is inclined.

Therefore, in this state, the board insertion portion 6 of the connector pin 5 cannot be inserted into the through hole 21 of the board 3.

For this reason, as described in [Means for Solving the Problems], a jig having pins having exactly the same arrangement as the arrangement of the terminals 8 of the module 1 is used.

By inserting the connector pin 5 into the terminal holding portion 7 having a spring force, the central axis of the connector pin 5 and the central axis of the through hole 21 are aligned. After that, by inserting the board insertion parts 6 of the connector pins 5 into the through holes 21 of the board 3, all the board insertion parts 6 of the connector pins 5 can be inserted into the through holes 21 of the board 3 at the same time without buckling and breaking them.
can be inserted into. Then, the jig may be pulled out from the terminal holding portion 7 of the connector pin 5.

As a result, the center axis of the connector pin inserted into the hole (not shown) of the mold of the connector 2 is aligned with the center axis of the through hole (not shown) of the board 3 into which the connector pin will be inserted.

The jig pin 10 of the jig 12 is held by the spring force of the terminal holding portion of the connector pin.

In this state, the insertion head 17 rises, pulls up the jig 12 and the connector 2, and moves along the rail 20 from above the connector supply section 13 to two sides of the laser measuring machine 14. Then, the position of the connector pin is measured by the laser of the laser measuring device 14.

Separately from this, a through hole position detection camera 16 attached to the rail 20 detects the position of a through hole (not shown) in the substrate 3 on the substrate table 15.

Next, the position of the connector pin to be inserted into the through hole, that is, the position of the insertion rod 17, is determined based on the position data of the connector pin and the position data of the through hole.
