Description

[Detailed Description of the Invention] Industrial Application Field The present invention is applicable to the implementation of edge connectors, such as those in which a receptacle connector is attached to the edge portion of a wiring board and connection to other connectors is made possible using the connector as a medium. Regarding the mechanism, in particular, the edge portion of the wiring board is held in the board insertion hole of the edge connector, and the contacts that protrude from the insertion hole are mounted on contact pieces arranged on the upper and lower surfaces of the edge portion of the wiring board. This invention relates to an improvement in the mounting mechanism of an edge connector that is connected and soldered.

Prior Art As shown in FIGS. 1 and 2, the entire body of a conventional edge connector 1 is made of an integrally molded structure, and two rows of contacts 2 are protruded from the side surface of the body. A board insertion port 3 is extended between the rows, the connector 1 is held onto the edge portion 5 of the wiring board 4 through the board insertion port 3, and the connector 1 is secured to the edge portion with a screw 6 passing through the edge portion 5. At the same time, the contacts 2 arranged with the board insertion port 3 as a boundary are soldered to the surfaces of contact pieces 7 arranged on the upper and lower surfaces of the edge portion 5 of the wiring board 4.

Problems to be Solved by the Invention However, in the case of the edge connector 1 described above, when inserting the edge portion of the wiring board 4 into the board insertion port 3, it is difficult to insert the edge portion between the rows of contacts 2. Since the contact 2 is pushed in, there is a risk that the contact 2 may be deformed at this time.

In addition, in order to solder the contact 2 to the surface of the contact piece 7, solder paste 8 is applied to the surface of the contact piece 7 in advance.
However, as shown in FIG. 3, when the edge connector 1 is pushed in, the contacts 2
The solder paste 8 is rubbed on the top surface of the contact piece 7.
The disadvantage is that it displaces the solder paste and removes the solder paste on the contact surface. Furthermore, if the contacts 2 are introduced into a heating furnace and heated in this state, sufficient fusion with the contact piece 7 on the contact surface of the contact 2 cannot be ensured, resulting in a lack of reliability. In addition, the displaced solder paste 8 may Due to heating, the solder may flow further to the side and cause a short circuit with the solder that has flowed out on the adjacent contact piece, resulting in a connection defect.

Also, looseness tends to occur between the board insertion port 3 and the edge portion 5 of the wiring board 4, and it is necessary to secure it to the wiring board 4 with screws 6 before inserting it into the heating furnace.
This makes work more complicated.

The present invention was created to rationally solve the above-mentioned problems.

Means for Solving the Problems The present invention, as a means to solve the above problems, divides the edge connector into two at the board insertion port, and each half connector is individually filled and combined with the edge of the wiring board. Then, while holding the edge part in the board insertion hole, the contacts of one half connector and the other half connector were respectively placed on the contact piece, and therefore on the solder paste on the surface of the contact piece. After that, the wiring board is placed in a heating furnace for soldering, and a handle hole is provided at the edge of the wiring board, and one or both of the boards of the halved connector are inserted into the handle hole. A handle is inserted into the inner surface of the mouth to determine the relative position of the half-split connector and the wiring board.

According to the present invention, each half connector having contacts in each row is opened and filled into the edge portion of the wiring board, and the edge portion is held in the board insertion hole and placed on the contact piece. Therefore, there is no risk that the contact will be deformed by the edge, and the risk of the contact rubbing against the surface of the wiring board contact piece and pushing away the solder paste can be eliminated, and sufficient solder paste can be applied to the contact surface. Highly reliable solder fusion between the piece and the contact can be expected.

Further, each half connector can be closed to the edge of the wiring board, and the inner surface of the board insertion port can be brought into close contact with the upper and lower surfaces of the edge, and the edge can be held in the insertion port without play.

In addition, by inserting the handle into the handle hole provided at the edge of the wiring board, it is possible to position the half connectors relative to each other and the wiring board, and therefore to position the contacts of both half connectors relative to the contact piece of the wiring board. Proper positioning can be achieved. Further, the two halves of the connector can be connected by the handle and the handle hole.
