DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for manufacturing a hot-swap connector, and more particularly to a method for manufacturing a hot-swappable connector which has a good assembling property and can be easily manufactured.

[0002]

2. Description of the Related Art A conventional hot-swap connector, for example, a receptacle connector with a shell will be described by way of example with reference to FIGS. 4 (a), (b), (c), (d) and FIG. As shown, the insulator 60 is provided with one type of contact 61 at predetermined intervals and alternately in the upper and lower positions, and the contact timing with the contact of the mating connector is staggered. There is.

By the way, in the hot-swap connector of the above type, when the contact pitch becomes small, two adjacent contacts 61 are provided as shown in FIG.
Are being processed at the same time. In this case, the press feed pitch a is two contact pitches b.

The contact 61 is assembled into the insulator 60 by temporarily inserting the contact 61 from the position shown in FIG. 7A into the insulator 60 in a state where the contact is connected to the carrier 63, as shown in FIG. 7B. . The press-fitting shoulder portion 61 provided behind the press-fitting portion of the contact 61.
A is pressed by a jig and press-fitted into the insulator 60. After that, the carrier is cut as shown in FIG. Then, from this state, as shown in FIG.
The contact 61 was press-fitted further deeply to alternately shift the position of the contact portion 61b.

By the way, the above-mentioned connector is connected to the board by SM.
When the T soldering connection is performed, the connection portion after being assembled in the insulator is displaced. Therefore, the SMT terminals are usually cut and aligned in order to facilitate the inspection after soldering. This cutting of the terminal was performed while ensuring the length of the short SMT portion (the one that is press-fitted only once).

[0006]

In the conventional hot-swap connector, as described above, the number of man-hours for assembling the contact into the insulator is large, and the assembling cost is accordingly high.

When applied to the SMT type, the SMT portion of the contact is displaced, the terminal portion has to be further cut, and the number of manufacturing steps is further increased. In addition, the terminal must be cut with a short length of the SMT portion being secured, and the depth dimension of the connector becomes large and the soldering characteristics are not stable.

The present invention has been proposed in view of the above problems of the prior art, and provides a method of manufacturing a hot-swap connector in which the above-mentioned conventional drawbacks are eliminated, the number of assembly steps is small, and the manufacturing cost is low. With the goal.

[0009]

In order to solve the above-mentioned problems, the present invention is accommodated and held in an insulator so that the connection timings of the respective contacts are deviated when the receptacle connector and the plug connector are mated and connected. In the method for manufacturing a hot-swap connector, in which the contact portions of the contacts are alternately arranged in the upper and lower positions, the contact of one of the connectors is composed of a long contact and a short contact. Is formed in a state in which the positions of the respective contact parts are substantially the same and the positions of the press-fitting shoulder parts are vertically displaced, and both contacts are alternately and integrally connected to the carrier. Temporarily insert it into the insulator, separate both contacts from the carrier, and insulate both contacts so that the positions of the press-fit shoulders are almost the same. Assembling by press-fitting the over data, also the manufacturing method of the hot-swap connector to set the width of the contacts differently is employed as means.

[0010]

According to the present invention, with the above configuration, when the contacts are temporarily inserted into the insulator, the carrier is removed, and the press-fitting shoulder portions of the respective contacts are pressed to forcefully insert the contacts into the insulator. As a result, the assembling of the contact into the insulator is completed by one press-fitting operation.

Further, according to the present invention, both the contacts can be arranged such that the widths of the adjacent contacts are alternately increased and decreased by the above-mentioned single operation.

[0012]

Embodiments of the present invention will be described below with reference to the accompanying drawings.

FIG. 1 is an explanatory view showing a hot-swap connector according to the present invention. FIG. 1 is a perspective view showing a state before connecting a plug connector and a receptacle connector, and FIG. FIG. 3 is a perspective view showing a state in which the connector and the receptacle connector are connected, and FIG. 3 is an explanatory view showing contacts used in the connector of the present invention.

In the embodiments of the invention described below,
The case of application to the receptacle connector will be described.

In the receiving hole 10a of the insulator 10 of the receptacle connector 1 shown in FIGS. 1 and 2, cantilever type contacts 11 and 12 are provided on both sides for conducting contact with the contact 31 of the plug connector 3. Contact 11 of this receptacle connector 1,
In order to shift the contact timing with the contact 31 of the plug connector 3, the positions 12 of the contact 11 and the contact 12b of the contact 12 are alternately arranged above and below. In the following description, for convenience of explanation, a contact whose contact portion is on the lower side (plug connector side) and comes into contact with the contact of the plug connector first is referred to as a long contact 11, and the contact portion is on the upper side and contacts of the plug connector. Those that come into contact with later are called short contacts 12.

Press-fit shoulders 11a and 12a, which are portions to be pressed when press-fitted into the insulator 10, are formed in the contacts 11 and 12 in substantially the same shape.

In the receptacle connector shown in FIGS. 1 and 2, the long contact 11 and the short contact 12 are pressed into the insulator 10. A feature of the present invention is to reduce the number of assembling steps when press-fitting the contacts 11 and 12 into the insulator 10. Therefore, as shown in FIG. 3, both contacts 11 and 1 used in the connector of the present invention.
The two are arranged alternately and are formed by, for example, press molding while being integrally connected to the carrier 20.
Reference numeral 21 in the drawing denotes a connecting portion of the carrier 20 that integrally connects both the adjacent contacts 11 and 12.

As shown in FIG. 3, the contact portions 11b of both contacts 11 and 12 integrally connected to the carrier 20 are
The positions of the contacts 12b in the longitudinal direction are substantially the same. That is, at this stage, the distances from the contact portions 11b and 12b to the connection portion 21 are set to be substantially the same.

Further, the press-fitting shoulders 11a and 12a are arranged so as to be vertically positioned from the pressing stage. That is, the press-fit shoulder 11a of the long contact 11
Is located above the connection portion 21, but the short contact 1
The second press-fitting shoulder portion 12a is located near the connection portion 21 or at an equivalent position.

At the boundary between the contacts 11 and 12 and the connecting portion 21, for example, a half cut or a notch is formed so that the contacts 11 and 12 can be easily broken.

Next, both contacts 1 as shown in FIG.
An operation of assembling 1, 12 into the insulator 10 as shown in FIGS. 1 and 2 will be described.

The contacts 11 and 12 connected to the carrier 20 shown in FIG.
Temporarily insert into a. Then, in this state, the carrier 20 is broken off at the connecting portion 21. Next, both contacts 11, 1
The press-fitting shoulders 11a and 12a of 2 are pushed into the contact insertion surface of the insulator 10 with a jig. At this time,
Although the positions of the press-fitting shoulders 11a and 12a are different from each other, they are pushed in so that they are in the same position. Then, the position of the contact portion 11b of the long contact 11 is located below the position of the contact portion 12b of the short contact 12, thereby forming a hot-swap structure.

The connection portion 1 of both contacts 11 and 12
Since 1c and 12c are formed so as to have substantially the same shape with the press-fitting shoulder portions 11a and 12a as a reference, after being assembled in the insulator 10, as shown in FIG. 1 and FIG. It is in a state of being. The connection portions 11c and 12c of the contacts 11 and 12 face the substrate 5.

The long contact 11 and the short contact 12 shown in FIG. 3 have the same width. In the present invention, for example, FIGS.
As shown in, the long contact 11 may be wider than the short contact 12. Alternatively, the reverse is also possible.

Although FIG. 1 and FIG. 2 show the contacts 11 and 12 arranged in two rows so as to face each other, the present invention may be arranged in one row or may be arranged in three rows or more. It goes without saying that even if it is a thing, it can be applied. If there are multiple rows of contacts and the wide type and the normal type are arranged so as to face each other, one contact (wide type contact) is used for ground and the other (normal width contact) is used for signal. Then, it is possible to obtain a connector having an excellent shield effect.

[0026]

As described above, according to the present invention, when the contacts are temporarily inserted into the insulator, the carrier connecting the respective contacts is removed, and then the press-fitting shoulder portions of the respective contacts are pressed. Since it is decided to forcibly insert the contact into the insulator, the assembling of the contact to the insulator is completed by one press-fitting operation. Moreover,
Since the positions of the contact portions can be alternately changed in the vertical direction by a single press-fitting operation, even with a hot-plug connector, the number of assembly steps can be reduced and the manufacturing cost can be reduced.
