DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a connector,
More specifically, it belongs to a connector with a film cover in which the projecting portion of the contact is protected by a film cover.

[0002]

2. Description of the Related Art As shown in FIG. 6, a conventional connector includes a connector 11 including an insulator 12 and a contact 13 provided on the insulator 12 and having a protruding portion 131 protruding from the insulator 12.
Exists.

When mounting this type of connector on a printed circuit board, generally, the upper surface of the insulator is sucked by an automatic mounting apparatus, the connector is transported to a predetermined position on the printed circuit board, and then soldered onto the printed circuit board. It consists of

Further, in this type of connector, since a part of the contact protrudes as described above, when mounting another component on a printed circuit board after mounting the connector, the other component is erroneously inserted into the protruding portion of the contact. In many cases, causing the contacts to deform.

In order to solve this problem, a connector 15 with a resin cover has been invented as shown in FIG. In the connector 15 with a resin cover, the resin cover 16 covers the entire connector. The resin cover 16 is provided with an insulator 17 by engagement of the concave portion and the convex portion.
The resin cover 1 is detachably mounted to protect the protruding portion of the contact 18.
6 has such a rigidity that it cannot be bent.

[0006]

As described above, in this conventional connector with a resin cover, the entire connector is covered with the resin cover, so that the size of the entire connector including the resin cover increases. Therefore, there is a problem that the mounting space is significantly larger than that of a normal connector having no resin cover, which is disadvantageous in terms of mounting density.

Further, in the conventional connector with a resin cover, an existing transport tray cannot be used, and even if a dedicated tray is made, the number of trays that can be stored in one tray is reduced.

Further, in the conventional connector with a resin cover, since the resin cover is locked to the insulator by the engagement between the concave portion and the convex portion, it takes time to remove the resin cover, and furthermore, the resin cover is removed. Since a strong force is required, there is also a problem that a load is applied to the soldered portion of the connector.

[0009] Therefore, an object of the present invention is to protect the projecting portion of the contact, to provide a mounting space equivalent to that of a normal connector, to use an existing transport tray, An object of the present invention is to provide a connector with a cover that allows the cover to be easily removed.

[0010]

According to the present invention, in a connector including an insulator and a contact provided on the insulator and having a protruding portion protruding from the insulator, the protruding portion of the insulator protrudes. On the side, two protrusions are formed so as to sandwich the protrusion, and the protrusion is covered with the film cover by inserting both ends of the film cover into these grooves. Is obtained.

[0011]

According to the connector with the film cover of the present invention,
On the insulator side where the projecting portion of the contact protrudes, two grooves are provided so as to sandwich the protruding portion, and by inserting both ends of the film-like cover into these grooves, the contact with the film-like cover is formed. Is formed so as to cover the protruding portion. Therefore, since the film-shaped cover covers only the minimum necessary projecting portions of the contacts, the size of the entire connector is hardly increased by the film-shaped cover. It is almost the same as the connector.

Further, since the size of the entire connector is substantially the same as that of a normal connector, an existing tray can be used.

Further, since the film-shaped cover is merely inserted into the groove of the insulator, the film-shaped cover can be removed easily and without applying force.

Next, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view of a pin connector with a film cover according to an embodiment of the present invention, FIG. 2 is a perspective view of a main part of the pin connector with a film cover shown in FIG. 1, and FIG. Perspective view of the pin connector with a cover with the film-shaped cover removed,
4 is an exploded view of the film-like cover of the pin connector with a film-like cover shown in FIG. 1, FIG. 5 shows the pin-like connector with a film-like cover shown in FIG. 1, and FIG. FIG. 2B is a cross-sectional view showing a state where the film cover is attached.

Referring to FIGS. 1 to 5, a pin connector 1 with a film cover according to the present embodiment is mounted on a printed circuit board (not shown), and includes an insulator 2 and a plurality of pin contacts. 3 and 2 fixed terminals 4
And a film-like cover 5.

The insulator 2 has a substantially housing shape. Grooves 2 are provided at the upper edge and the lower edge of the insulator 2 on the side of the mating side with the mating connector (not shown).
1 and 22 are formed, and these grooves 21 and 22 are
It is arranged so as to sandwich a contact portion 31 described later.

The plurality of pin contacts 3 are arranged on the insulator 2 in two upper and lower stages. Each pin contact 3
Has a contact portion 31, a press-fit portion 32, a bent portion 33, and a soldered portion 34, as is apparent from FIG. The contact portion 31 is a portion that contacts the socket contact of the mating connector, and protrudes at a right angle from the fitting-side end surface of the insulator 2. That is, in the present embodiment, the contact portion 31 is a protruding portion of the pin contact 3. The press-fit portion 32 is connected to the contact portion 31 and is press-fitted into the insulator 2, whereby the pin contact 3 is held by the insulator 2. The bent portion 33 is connected to the press-fit portion 32 and is bent substantially in a crank shape. The soldering portion 34 is a portion to be soldered to the conductor pattern of the printed circuit board, and is connected to the bent portion 33.

The two fixed terminals 4 are respectively implanted below the two ends of the insulator 2 in the longitudinal direction, and these fixed terminals 4 are soldered to a ground pattern on a printed circuit board.

As is apparent from FIG. 4, the film-like cover 5 has a substantially rectangular film shape and is colorless and transparent.
It has flexibility. At both ends of one side edge portion 51 of the film-shaped cover 5, convex pieces 52 are formed. These convex pieces 52 are for positioning the film-shaped cover 5 by abutting on both end faces in the longitudinal direction of the insulator 2. A ridge 53 is formed on the other side edge of the film cover 5. The film-shaped cover 5 is attached to the insulator 2 by inserting one side edge 51 into the groove 21 of the insulator 2 and inserting the ridge 53 on the other side edge into the groove 22 of the insulator 2. As described above, since the grooves 21 and 22 are provided so as to sandwich the contact portion 31 of the contact 3, the film-like cover 5
When the grooves 21 and 22 are inserted at both ends, the film-shaped cover 5 covers the contact portion 31 of the contact 3.

In this embodiment, the pin connector 1 is used.
The present invention is applicable not only to pin connectors but also to socket connectors and the like. Further, in the present embodiment, the contact portion 31 of the pin contact 3 is covered with the film-shaped cover 5, but the present invention is not limited to this. Can also be:
If the contact protrudes from the insulator,
Any can be covered with a film-like cover.

[0021]

According to the connector with a film cover of the present invention, since only the projecting portion of the contact is covered with the film cover, the size of the entire connector is hardly increased by the film cover. Therefore, the mounting space can be made substantially the same as a normal connector without a cover.

Further, since the size of the entire connector is substantially the same as that of a normal connector, an existing tray can be used.

Further, since the film-like cover is simply inserted into the groove of the insulator and attached, the film-like cover can be removed easily and without applying force.

Further, since the film cover has flexibility, even if there is not much space around the connector,
The film cover can be easily attached to and detached from the insulator.
