DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an insulator and a jig for holding the same, and more particularly to an insulator for a connector in which a number of contacts are incorporated in a pitch direction of the insulator and a jig for holding the same.

[0002]

2. Description of the Related Art Conventionally, when a large number of contacts are incorporated into an insulator of a connector in a pitch direction of the insulator, a predetermined number of insulators 50 having a substantially rectangular parallelepiped shape are arranged in a jig 60 as shown in FIG. In addition, a contact (not shown) is incorporated.
A plurality of projections 61 are formed on the jig 60 along the thickness direction of the insulator 50, and the jig 60 is fixedly held and positioned so as to sandwich the insulator 50 with the projections 61. By the way, as a first method of incorporating the contact into the insulator using the jig 60, the contact is preliminarily positioned on the jig 60 before the insulator 50 is fixedly held on the jig 60, and then the insulator 50 is removed. There is a method of assembling the contact while guiding the jig 60. As another method, there is a method in which the insulators 50 are first arranged on the jig 60, and then the contacts are inserted into the insulators 50.

FIG. 7 shows another prior art.
In some cases, the insulators 50 having a substantially rectangular parallelepiped shape are arranged side by side so as to be in contact with each other in the thickness direction, and then the contacts are incorporated. In this case, the insulators 50 are arranged and placed as shown in FIG. 7 using a jig that covers the whole of the plurality of arranged insulators 50 from the outside. And the insulator 5 of the contact in this case
As a first method, the contacts are positioned and placed on a jig before the insulator 50 is fixedly held on a jig (not shown).
There is a method of assembling into a contact while guiding 0 to a jig. As another method, there is a method in which the insulator 50 is first arranged in a jig, and then a contact is inserted into the insulator 50. However, in this case,
When incorporating the insulator 50 into the contact,
A jig for positioning the contact is required.

[0004]

However, in the first prior art shown in FIG. 6, the arrangement pitch b of the insulators 50 when the contacts are assembled is determined by the thickness c of the insulator 50 and the thickness of the protrusion 61. The value is equal to or slightly larger than the sum of the dimension d. For this reason, the arrangement pitch of the contacts in a state where the contacts are integrally connected by the carrier must be equal to the arrangement pitch b of the insulators, and the arrangement pitch of the contacts is more than necessary by the thickness d of the protrusion. And increased the cost of the connector.

In the second prior art shown in FIG. 7, when the insulators 50 are arranged, the pitch e of the insulators between both ends is 1 to 1 from the number of the insulators 50.
Is multiplied by the thickness c of the insulator 50, and the pitch e becomes inaccurate because the manufacturing tolerance of the thickness c of the insulator 50 accumulates. Therefore, when the insulators 50 are arranged in advance and the contacts are inserted later, there is a disadvantage that the contacts are difficult to be inserted due to the difference between the arrangement pitch of the insulators 50 and the arrangement pitch of the contacts, and the assemblability is deteriorated. Was. Also, when mounting the insulator on the contacts aligned on the jig, the insulators are not individually positioned with respect to the contacts,
There was also the inconvenience of deforming the contacts during assembly.

It is possible to perform positioning by a jig.

[0015]

Next, an embodiment of the present invention will be described. FIG. 1 is a perspective view showing a first embodiment of an insulator of the present invention and a jig for holding the same. FIG. 2 is a perspective view showing a part of the back side of the insulator shown in FIG.
FIG. 2 is an explanatory view showing a connector obtained by using the insulator and the jig shown in FIG. 1.

As shown in FIG. 1, the insulator 10
Are arranged along the predetermined direction A on the jig 30. Each of the insulators 10 has a U-shape in which legs are arranged on both sides in an upright state. Grooves 11 extending in the up-down direction B, which is the press-fit direction of the contacts 20, are formed at lower ends of both side surfaces of the insulator 10. This groove 11 is formed in an open state at the lower end side, as best seen from FIGS. As shown in FIG. 3, the length g of the groove 11 is set slightly longer than the insertion depth f of the contact 20 into the insulator 10.

In FIG. 2, reference numeral 12 denotes a positioning projection for positioning the connector with the board when soldering the connector to the board (not shown). Since the protrusion 12 protrudes from one end surface in the thickness direction of the insulator 10, the plurality of insulators 10 on the jig 30 are equal to or slightly larger than the thickness c of the insulator 10 excluding the protrusion 12. When arranged at the arrangement pitch,
Since the protrusion 12 interferes with the adjacent insulator 10, in order to prevent this, the lower end of the side surface of the insulator 10, at the corner opposite to the portion where the protrusion 12 is formed, is provided. When the insulators 10 are arranged, a notch-shaped escape groove 13 for accommodating the projection 12 is formed.

A plurality of projections 31 are formed inside the side wall of the jig 30 holding the plurality of insulators 10 at predetermined pitches along the predetermined direction A so as to extend in the vertical direction B. The arrangement pitch b of these projections 31
Is substantially equal to the thickness c of the insulator 10. Therefore, the arrangement pitch of the insulators 10 is equal to the arrangement pitch b of the projections 31, so that the insulator 10
Is substantially equal to the thickness dimension c of the insulator 10. The insulator 10 is inserted between the projections 31 and is kept in an aligned state. Vertical direction B
In (2), the length of the protrusion 31 is shorter than the length of the groove 11 of the insulator 10 and longer than the insertion depth f of the contact 20 into the insulator 10.

On the surface of the jig 30 on which the insulator 10 is received, the carrier 21 of the contact 20 is inserted so that the holding groove 32 for holding the contact 20 on the jig 30 extends in the alignment direction. Is formed. The contact 20 on the jig 30 is positioned in the carrier extending direction by a guide pin 40 that penetrates through the pilot hole 22 of the carrier 20 through an insertion hole 33 formed in the jig 30.

A chamfer 3 is formed at one open end of the holding groove 32.
2a is formed. The chamfer 32a is formed when the contact 20 is inserted into the jig, that is, when the carrier 21 is inserted into the holding groove 32, when the contact 20 is inserted in the vertical direction B in FIG. Therefore, if the carrier 21 of the contact 20 is inserted into the chamfered portion and inserted in the direction indicated by the white arrow in order, the contact 20 can be easily fixed even if the contact 20 is wound. Can be loaded into

The contact 20 is shown in FIG.
As shown in (d), two types of contacts 20 are provided alternately, but in FIG. 1, only one type of contact is illustrated and described for convenience.

Next, the assembly process will be described. First, the contacts 20 are loaded on the jig 30 in an aligned state as described above, and then the insulator 10 is connected to the projection 31 of the jig 30.
And inserted into the jig 30. In this case, the plurality of insulators 10 are collectively performed, and the contacts 20 are pressed into the respective insulators 10 to obtain a connector as shown in FIG.

The groove 11 formed in the insulator 10 is formed at the center in the thickness direction of the insulator. As shown in FIGS. 4 and 5, the groove 11 is formed at one end of the insulator 10 in the thickness direction. Alternatively, the same effect can be obtained even if it is formed at both ends.

In the above-described embodiment, the contacts 20 are aligned and held in advance on the jig 30 and the insulator 10 is loaded on the jig 30 and assembled in this state. The present invention is not limited to this, and it goes without saying that the present invention can also be applied to a device in which the insulator 10 is loaded in the jig 30 first and a contact is inserted and assembled later.

[0025]

As described above, according to the present invention, the insulator can be aligned in the jig with a size equal to or slightly larger than the thickness of the insulator. Can be configured with the required minimum dimensions, and the connector can be manufactured at low cost. Even if the connector has a projection for positioning with respect to the substrate, if the escape groove is formed, the height of the projection does not become a problem, and the thickness of the insulator excluding the projection is reduced. The arrangement pitch of the insulators can be set with substantially the same dimensions as those described above.

Further, according to the jig of the present invention, since the insulators can be aligned with a smaller arrangement pitch than the conventional arrangement, the arrangement pitch of the contacts can be made smaller than the conventional arrangement, and as a result, the cost of the connector can be reduced. It can be reduced more than before. Further, in the case of the jig according to claim 7, since the jig guides the insulator before the contact is inserted into the insulator, the contact can be reliably inserted, and a situation such as deforming the contact does not occur. .
