Abstract

PURPOSE: To reduce assembly manhours by reducing the number of part items and to enhance the property of radiating heat for the protection of memory and for miniaturization. CONSTITUTION: This connector has an insulator 2 to which a contact 3 is secured and a pair of side frame portions 41 which project perpendicularly from both sides of the insulator. The side frame portions 41 are formed by punching of a metallic material by means of a press in such a way that they are integrated and connected together at a connection 40 at one end. A latch 43 and a board locking portion 45, by which a mating board inserted from above are locked into place, are formed in each side frame portion 41. Locking windows 46 formed in both of the side frame portions are locked to locking projections 23 formed on the insulator, so as to assemble the side frame portions and the insulator together.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connector, and more particularly to a connector for increasing the internal memory of a personal computer or the like, in which a mating board is inserted from above and fixed by a latch.

[0002]

2. Description of the Related Art Conventionally, as this type of connector, for example, there is a type as shown in FIGS. That is, in the conventional connector, the upper contact (not shown) and the lower contact 3 are press-fitted into the connecting base portion 51 of the U-shaped resin frame 5 and the side frame portions 51 and 51 ′ of the frame 5 are connected. Latches 61 and 61 ', which are engaged with the mating substrate 8 respectively, are integrally attached to the tips. Under the members forming these latches 61, 61 ', fixing portions 71, 71' for fixing to a substrate (not shown) are formed.

[0003]

However, in the above-mentioned conventional connector, since the latches 61 and 61 'are formed separately from the both side frame portions 51 and 51' of the frame 5, the latch 61 is formed. , 61 ′ must be attached to both side frame portions 51, 51 ′ of the frame 5, respectively, which complicates the working process.

Further, in the above-mentioned conventional connector, since the frame 5 is formed of the resin material, the heat generated from the connected board is likely to stay in the connector, which adversely affects the memory.

Further, since the frame 5 is made of a resin material, it cannot be made thin in terms of strength, and the frame is inevitably made thick, which is against the demand for miniaturization. It was

The present invention has been proposed in view of the above problems of the prior art, and it is possible to reduce the number of assembly steps by reducing the number of parts, protect the memory by improving the heat dissipation, and downsize the connector. An object of the present invention is to provide a connector for increasing the internal memory of a personal computer or the like, in which a mating board is inserted from above and then fixed by a latch.

[0007]

According to the present invention, there is provided an insulator for fixedly holding contacts arranged at a predetermined pitch, and a pair of side frame portions projecting from both sides of the insulator in a direction perpendicular to each other. In a connector in which a latch for fixing a mating board inserted from above and a board fixing portion are formed in the pair of side frame portions, the pair of side frame portions are separately engageable with an insulator. A connector characterized in that it is configured and is formed by press-punching a metallic material so as to be integrally connected by a connecting portion at one end side thereof.

[0008]

According to the present invention, the assembly of the connector is completed only by engaging and mounting the side frame portion, which is formed separately from the insulator portion, into the insulator portion.
Further, since the frame portion is made of a metal material, it has good thermal conductivity, and heat generated from the connected substrate can easily escape.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the accompanying drawings. 1 is a perspective view showing a disassembled state of a connector of an embodiment of the present invention, and FIG. 2 is a perspective view showing an assembled state.

As shown in FIG. 1, in the connector of this embodiment, a contact 3 is press-fitted and held in a mating substrate receiving port of a box-shaped insulator 2. Although only the lower contact 3 is shown in the drawing, the upper contact is also present on the side facing the lower contact 3.

Engaging projections 23 that engage with engaging windows 46 formed in the frame 4 described later are formed on both side surfaces of the insulator 2. Further, a step portion 25 that locks and holds the connecting portion 40 of the frame 4 is formed on the front side of the upper surface of the insulator 2 in the longitudinal direction.

The frame 4 is formed by press-molding a metallic material, and includes a connecting portion 40 and the connecting portion 40.
And side frame portions 41 extending in the right-angled direction from both ends. On the tip ends of these side frame portions 41, a slit 42 that opens to the tip is formed at the center in the vertical direction, and on the upper side of the slit 42, a latch 43 for fixing and holding a mating substrate (not shown). Are formed. The latch 43 is bent inward to fix and hold the mating substrate. In addition, the slit 42
A substrate fixing portion 45 is formed on the lower side.

An engagement window 46 that engages with the engagement protrusion 23 of the insulator 2 is formed on the rear end side of the side frame portion 41.

Next, the assembling of the frame 4 to the insulator 2 will be described.

The connecting portion 40 of the frame 4 is applied to the step portion 25 of the insulator 2, and the engaging window 46 formed on the rear end side of the side frame portion 41 is fitted into the engaging protrusion 23 formed on the side surface of the insulator 2. 2 is completed as shown in FIG.

[0016]

As described above, according to the present invention, the latch and the board fixing portion are integrally formed on the side frame, and the side frame portion is integrally formed by the connecting portion. Therefore, the number of parts can be reduced, the number of assembling steps can be reduced, and the manufacturing cost can be reduced.

Further, according to the present invention, since the frame is formed by stamping from a metal material, the thermal conductivity is good, and the heat generated from the connected substrate is easily released. It does not adversely affect the memory.
