Abstract

PURPOSE:To remarkably increase the strength of a pin for a reinforcing leg without enlarging an insulating housing by performing the insert-forming of two parallel metal wires in such manner as to pass them through the portion near the insulating housing, and folding both the ends of the wires which serve as the reinforcing legs. CONSTITUTION:A pin contact press-fitting hole 13 on the bottom surface 12 of an insulating housing 11. Also, two wires 14a and 14b are passed through the portions near the longitudinal ends of the insulating housing 11 in such a manner as to be parallel to the bottom surface thereof, and is insert-formed. Then, a pin contact 15 is press-fitted in the hole 13 to the specified position. The inserted wires 14a and 14b are cut by the specified length and are folded at the base portion right to the bottom surface side. The folded wires serves as reinforcing legs 16a and 16b, thus so obtain a pin connector for a printed substrate.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a type of connector for printed circuit boards with reinforcing legs to strengthen the mounting strength, among connectors used by being attached to printed circuit boards of various electronic devices. It is.

2. Description of the Related Art The prior art will be explained with reference to printed circuit board connectors shown in FIGS. 5, 7, and 6.

In the figure, reference numeral 1 denotes an insulating housing, the bottom surface 2 of which has a hole for press-fitting a pin contact, and a hole 4 for reinforcing R1tJ fluid in a square near the longitudinal end of the housing 1. Then, pin contacts 5 and reinforcing leg pins 6 are press-fitted into these holes 3 and 4 to predetermined positions, respectively, to complete the printed circuit board pin connector with reinforcing legs shown in FIG. 5.

Here, 5a and 6a are protrusions provided to strengthen the force for press-fitting the pit contact 5 and the reinforcing leg pin 6 into the press-fitting holes 3 and 4, respectively.

Problems to be Solved by the Invention However, in recent printed circuit boards for hermetically sealed devices, it is becoming difficult to increase the size of the connector by adding reinforcing legs to the connector.

Therefore, in the above-mentioned conventional printed circuit board connector with reinforcing legs, it is difficult to enlarge the housing 1 due to the reinforcing leg press-fit holes 4 provided in the squares of the bottom surface 2 of the insulating housing. 6 press-fit hole 4
The depth of the hole and the wall thickness around the hole could not be increased very much.

For this reason, the press-fit holding strength of the reinforcing leg pin 6 cannot be made too large, and there is a risk that the holding force as a reinforcing leg may become unstable due to heat, temperature changes, vibrations, etc. during use of the device when soldered. there were.

In addition, generally, the direction in which reinforcing leg pins are press-fitted into the squares on the bottom of the insulating housing is the opposite direction to the press-fitting direction of the pin contacts, so it is difficult to press-fit them at the same time, and the assembly process is time-consuming. was.

The present invention solves these conventional problems, and provides a printed circuit board connector in which the connector housing does not become large due to the addition of reinforcing leg pins, and the strength of the reinforcing leg pins is extremely strong. It is intended for the purpose of providing.

Means for Solving the Problems In order to solve the above-mentioned problems, the present invention insert-moldes two parallel metal wires that pass through near the ends of an insulating housing, bends both ends of each wire, and forms reinforcing legs. This is what we are trying to do.

Therefore, according to the present invention, the reinforcing legs are connected two at a time, and the connecting portions are embedded in the resin of the nosing, which requires extra space.Moreover, the holding strength of the reinforcing legs is It is large and stable.

Embodiment A first embodiment of the printed circuit board connector of the present invention is described below.
This will be explained using the printed circuit board pin connectors shown in FIGS.

In the same figure, 11 is an insulating housing, and its bottom surface 12
It has a pin contact press-fitting hole 13, and two wires 14a and 14b are fixed by insert molding near the longitudinal end of the hole 13 so as to penetrate parallel to the bottom surface of the housing.

As shown in FIG. 2, the pin contact 15 is inserted into the pin contact press-fit hole 13 of this housing 11
By press-fitting the wires 14a and 14b into a predetermined position, cutting the inserted wires 14a and 14b to a predetermined size, and bending them at right angles from their roots to the bottom side to form reinforcing legs 16a and 16b, the print shown in FIG. It is completed as a pin connector for circuit boards.

Although the above description has been made regarding a pin connector for a printed circuit board, it is also applicable to a socket connector for a printed circuit board in which the contact portion is a socket contact, and it goes without saying that this is within the scope of the present invention. .

Effects of the Invention As is clear from the above embodiments, the present invention provides (1) the reinforcing bottles are each integrally connected, and the connecting portion is formed by an insert in the bottom resin near the longitudinal end of the insulating housing. Since the reinforcing legs are embedded by molding, almost no extra space is required for the reinforcing legs.Furthermore, since the reinforcing legs are insert-molded into the insulating housing, the reinforcing leg retention strength is extremely high, and soldering requires no heat during installation. It is also stable against temperature changes and vibrations after it is installed in equipment.

(2) The reinforcing legs are formed by continuously molding the insulating housing at a constant pitch on two metal wires that are insert-molded near both longitudinal ends of the insulating housing, and then cutting and bending them. By using metal wires, it is easy to automate processes such as press-fitting pin contacts, and the assembly work can be streamlined.

It has the following effects.
