Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a sequence structure of the contacts in an electronic circuit package connector for connecting contacts of a female connector to a male connector.

(Prior Art) Generally, when connecting an electronic circuit package (hereinafter, referred to as a package) and a printed wiring board (hereinafter, referred to as a backboard), the package and the back are provided in order to prevent malfunction of the electronic circuit package. It is necessary to give a sequence to the connector that connects the board.

Therefore, the sequence structure of the conventional electronic circuit package connector will be described with reference to FIGS. FIG. 5 is a plan view of an electronic circuit package connector having a sequence in units of columns, FIG. 6 is a sectional view taken along line VI-VI of FIG. 5, and FIG.
The figure is a perspective view of the essential parts of the male and female contacts, 8th
The figure is a plan view showing a state in which the contacts are press-fitted into the female housing.

In the figure, reference numeral 1 is a male contact, and a male contact 4 is attached to a backboard 3 to which a male housing 2 made of an insulating material is attached.
Press-fit vertically and horizontally in parallel, and connect by soldering if necessary. On the other hand, reference numeral 5 denotes a female connector, a female housing 7 in which a plurality of holes 6 into which the front ends of the male contacts 4 are inserted are formed in parallel in the vertical and horizontal directions, a package 9 to which the female housing 7 is attached by screws 8 and the like, and this package 9 And the contact 10 connected to the. The contact 10 is integrally molded with a carrier 11 (see FIG. 8) by pressing to form a substantially comb tooth shape, a V groove portion 12 is formed in the rear portion for cutting with the carrier 11, and a front portion is formed. The notch 13 is formed, and the contact portions 1 on the front end sides that face each other and have V-shapes that are connected to each other at the connecting portion 14 adjacent to the notch 13.
5 and the contact portion 16 on the rear end side are formed, and the connecting portion 1
A circular boss 1 for press-fitting and locking with the female housing 7
7 is punched out in two places.

In the connector for electronic circuit package having such a structure, when assembling the female connector 5 by press-fitting the tip of the contact 10 into the hole 6 of the female housing 7, as shown in FIG. By press-fitting and locking in the housing 7, the press-fitting and locking position of the contacts 10 is changed in units of one row so as to have a sequence as shown in FIG. 6, and the V groove portion 12 of the contact 10 breaks and separates from the carrier 11. Is connected to the package 9 to assemble the female connector 5.

Therefore, when the male connector 1 and the female connector 5 are connected,
Since the press-fitting locking position of the contact 10 of the female connector 5 is changed on a row-by-row basis, the connection between the contact 10 and the male contact 4 of the male connector 1 has a sequence with a time shift.

(Problems to be Solved by the Invention) However, in the above-described electronic circuit package connector, the connector 10 is press-fitted and locked in the female housing 7 in a unit of one row, so that the connector can have a sequence only in a unit of one row. There is a problem that it is not possible to have an internal sequence.

This invention has been made to solve the above-mentioned problems, and its purpose is to improve the performance by providing a sequence in the same row of the connector, and to facilitate its manufacture. To do.

(Means for Solving Problems) In order to achieve the above-mentioned object, the present invention forms a contact portion of a contact so that only an arbitrary contact portion of the contact can be bent and raised.

(Operation) By doing so, any contact part of the contact is bent and bent as necessary, and the male contact is connected to the contact with a time delay by the position deviation of the contact part that is bent and bent. Can have a sequence.

(Embodiment) An embodiment of the present invention will be described below with reference to FIGS. 1 and 2 to 4.

FIG. 1 is a plan view showing an embodiment of the connector of the present invention, and FIG.
Fig. 1 is a sectional view taken along the line II-II in Fig. 1, Fig. 3 is a perspective view of a main part of a contact in which only the contact portion on the root side is bent and raised, and Fig. 4 is a plan view showing a state where the contact is press-fitted into a female housing. It is a figure. In these figures, reference numeral 18 denotes a female connector, and holes 20 for press-fitting and locking the front end of the contact 19 are formed in parallel in a vertical and horizontal directions in a female housing 21, and the housing 21 is fixed to a package 22 by screws 23.

In addition, the contact 19 has a carrier 24 without a press.
And a V-shaped groove 25 for breaking with the carrier 24 at the rear part and a notch 26 at the front part to connect at a connecting part 27 adjacent to the notch 26. A front-side contact portion 28 and a rear-end side contact portion 29, which are in the shape of a V shape, are formed so as to meet each other.
Female housings 2 are provided on the connecting portions 27 on both sides of 8, 29, respectively.
Two circular bosses 31 for press-fitting and locking the holes 20 of 1 are punched out and formed.

Reference numeral 32 denotes a male connector, which is a male housing 33 made of an insulating material.
The male contacts 35 are press-fitted in parallel in a plurality of rows and columns on the backboard 34 to which is attached, and are connected and fixed by soldering if necessary.

Next, the operation of the above configuration will be described. When the contacts 19 in the lateral row in the drawing are given a sequence, the contact portions 28 or 29 formed at the tip of the contacts 19 are shown in FIGS. 3 and 4. As shown, only the desired contact is bent and raised, and only the raised contact can be connected to the male contact 35 so that the connection between the male contact 35 and the contact 19 is delayed. That is, the male contact 35 and the contact portion 28 are not connected, but the male contact 35 is connected to the contact portion 29 on the rear end side later in time by the amount that the contact portion 28 on the front end side of the contact 19 is not present. You will get the sequence.

Further, when it is desired to provide a sequence to the contacts 19 in the vertical direction in the drawing, the contacts 19 are press-fitted and locked to the female housing 21 in units of one row as shown in FIG. As shown in FIG. 2, a sequence is provided by changing it in units of one column. That is,
If the contact 19 is not close to the insertion opening side of the male contact 35, the contact 19 is quickly connected to the male contact 35.
If 9 is moved away from the insertion opening side of the male contact 35, it will be connected to the male contact 35 later and have a sequence.

The female connector 18 is assembled by press-fitting and locking the tip of the contact 19 into the hole 20 of the female housing 21, breaking and separating the carrier 24 at the V groove 25, and connecting the contact 19 and the package 22.

Further, in this embodiment, the two contact points of the contact portion on the front end side and the contact portion on the rear end side are opposed to each other, but may be applied to a contact having three or more contact portions.

(Effects of the Invention) As described in detail above, according to the connector for electronic circuit package having the sequence according to the present invention, the contact is formed so that only an arbitrary contact portion of the contact can be bent and raised, and the arbitrary contact is formed. Since the portion is bent and bent, and the connection with the male contact is delayed in time by the amount of deviation of the contact portion, there is an effect that a sequence in the same row can be easily provided.

Further, since the contact manufacturing process only requires a simple additional process to the conventional manufacturing process, it has good manufacturability and can be manufactured at low cost.
