Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a circuit board connector which is projected on the outer surface of a case for accommodating a circuit board.

[0002]

2. Description of the Related Art Examples of this type include, for example,
There is a circuit board connector as disclosed in Japanese Patent No. 161583. 1 to 3 of this publication disclose a configuration in which a female housing 3 is assembled to a projecting piece 2 of a circuit board 1 as shown in the drawings. This protrusion 2 and female housing 3
Constitutes a female connector, and a male housing 6 as a male connector is fitted into this female connector. In the figure, 1a is a conductive pattern, 6a is an electric wire, and 7 is a terminal.

[0003]

However, in this structure, it is necessary to provide a cover (not shown) for protecting the circuit board 1, and since the cover and the female housing 3 are separate bodies, the number of parts increases. There is a problem. Moreover, since the work of assembling the female housing 3 to the circuit board 1 and the positioning between the cover and the female housing 3 are required, the number of assembling steps is increased and the product is expensive. It was

Therefore, an object of the present invention is to provide an inexpensive circuit board connector having a small number of parts and man-hours for assembling.

[0005]

In order to achieve this object, the present invention is provided with a cylindrical female housing that extends over the outer surface of the upper case and the outer surface of the lower case, and is arranged between the two cases. In the circuit board connector in which the flat terminal portion of the circuit board is disposed in the female housing from between the two cases, the female housing is integrally formed on the outer surface of the upper case. The circuit board connector is formed of a lower housing integrally formed on the outer surface.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIG.

1 (b) and 1 (c), 10 is a circuit board, and 11 in FIGS. 1 (a) and 1 (b) is a case (cable cover) for covering the circuit board 10. The case 11 is composed of an upper case 12 and a lower case 13.
On the outer side surface of the case 11, a flat, rectangular and cylindrical female housing 14 that straddles both cases 12 and 13 is provided.

The female housing 14 is composed of a channel-shaped upper housing 15 integrally formed on the outer surface of the upper case 12 and a channel-shaped lower housing 16 integrally formed on the outer surface of the lower case 13. ing.

The upper housing 15 includes a continuous wall 15a and side walls 15b and 15b provided on both sides of the continuous wall 15a.
Ribs 15c provided on each side wall 15b for reinforcing the side wall,
It has elastic locking pieces 15d extending from each side wall 15b to the lower housing 16 side. A claw portion 17 is provided at the tip of each elastic locking piece 15d, and the claw portion 17 and the side wall 15b are provided.
A recess 18 for holding the housing is formed between and.

The lower housing 16 has a continuous wall 16a.
And side walls 16b and 16 provided on both sides of the continuous wall 16a.
b and ribs 16 provided on each side wall 16b for reinforcing the side wall
c.

The lower housing 1 is provided in the recess 18.
The side wall 16b of 6 is engaged and held. The claw portion 17
Has an inclined guide surface 17a for guiding the side wall 16b of the lower housing 16 toward the recess 18 when the housings 15 and 16 are assembled.

A boss portion 12a is integrally formed on the upper case 12 near the upper housing 15. On the other hand, one end (one edge) of the circuit board 10 is integrally provided with a projecting piece-shaped flat terminal portion 10a (flat terminal) protruding from the one end (one edge). The circuit board 10 has a flat terminal portion 10
The portion near a is fixed to the boss portion 12a with a screw 19.

Next, the operation of the circuit board connector thus constructed will be described.

When assembling the circuit board connector having the above-described structure, the circuit board 10 is first fixed to the boss portion 12a with the screw 19. At this time, the flat terminal portion 10a is previously positioned between the side walls 15b, 15b of the upper housing 15.

Next, the upper case 12 and the lower case 13 are fixed together. At this time, the lower case 13
The lower housing 16 is replaced by the elastic locking piece 1 of the upper housing 15.
The lower housing 16 is provided between the tip portions of 5d and 15d.
The side walls 16b, 16b of the claws 17, 17 to guide the inclined guide surfaces 17a, 17a of the claws 17, 17 to provide elastic locking pieces 15d, 15d.
Engage with the recesses 18, 18.

The side walls 16b and 16b are inclined guide surfaces 1
When guided to the recesses 18 and 18 side by 7a and 17a, the elastic locking pieces 15d and 15d are elastically deformed in the directions away from each other. When the side walls 16b, 16b are engaged with the recesses 18, 18, the elastic locking piece 15
d and 15d are returned to their original state by their own elastic force. Thus, in the engaged state, the elastic locking pieces 15d,
Since 15d fixes the housings 15 and 16 to each other,
The cases 12 and 13 are also fixed.

[0017]

As described above, according to the present invention, a cylindrical female housing extending over the outer surface of the upper case and the outer surface of the lower case is provided, and the flat terminals of the circuit board disposed between the both cases. In the connector for a circuit board in which the portion is disposed in the female housing from between the both cases,
Since the female housing is composed of an upper housing integrally formed on the outer surface of the upper case and a lower housing integrally formed on the outer surface of the lower case, it is possible to attach the female housing to the circuit board. Since the cover and the female housing are not required to be positioned, the number of parts and the number of assembling steps are small, and the manufacturing cost is low.
