Problems to be Solved by the Invention However, the conventional L-shaped composite electrical connector as described above has the following problems.

(1) Since the capacitor element is directly attached to the connector contact by soldering, the assembly of the connector is difficult, the number of steps is large, mass production is not possible, and the cost is high.

(2) Since the capacitor element has been directly soldered to the connector contacts, if any one of the capacitor elements fails, the entire connector must be discarded as a defective one, It was very uneconomical.

(3) Since the capacitor element is structurally mounted near the printed circuit board, the soldered portion of the capacitor element may be melted by heat and removed during flow soldering to the back surface of the printed circuit board.

(4) Since the connector contact is soldered to the internal electrode of the capacitor element, the capacitor contact is deformed due to heating at that time, and the arrangement of the connector contact and the through hole arrangement of the printed circuit board do not match. , The connector may not be attached to the board.

(5) Since the mounting portion of the capacitor element is left bare, there is a risk of pride, dust, etc. adhering to it and a short circuit or insulation deterioration.

EFFECTS OF THE INVENTION Since the L-shaped composite electrical connector of the present invention has the above-described configuration, it exhibits the following effects.

(1) A composite component mounting case is provided separately from the insulating housing, and the composite component mounting case can be assembled to the insulating housing in a state where the composite component as a capacitor element is fixed to the composite component mounting case. As a result, the capacitor element can be easily incorporated into the connector, mass production is possible, and the cost can be reduced. That is, the insulating housing incorporating the connector contactor and the composite component mounting case incorporating the capacitor element can be separately manufactured, and the connector insulating housing and the composite component mounting case can be assembled according to the demand, so that the production management can be performed. Can be done easily.

(2) When only one of the capacitor elements becomes defective, the composite electrical connector can be reused by replacing only the composite component mounting case,
There is no waste such as discarding the entire composite electrical connector,
It will be very economical.

(3) Since the composite component, which is a capacitor element, is arranged at a position farther from the surface of the printed circuit board on which this composite electrical connector is installed, heat generated during flow soldering on the back surface of the printed circuit board causes There is no fear that the capacitor fixing element will melt and the capacitor element will fall off the connector.

(4) Since the connector contacts are not directly inserted and fixed to the internal electrodes of the capacitor element by soldering, the connector contacts may be deformed or the connector contacts may be misaligned. There is no fear. Therefore,
The problem that the connector contact is not inserted into the through hole arranged on the printed circuit board does not occur. Further, when the cover case is attached to the composite component mounting case assembled to the insulating housing, it is possible to prevent pride and dust from adhering, and prevent occurrence of short circuit and insulation deterioration.

(5) Moreover, since the composite component mounting member is assembled in the space above the intermediate portion 22 of the connector contact 20 which was originally a play space in the L-shaped electrical connector,
The L-shaped composite electrical connector can be formed by incorporating the composite parts without increasing the original height of the L-shaped electrical connector.

(6) Furthermore, since the composite component mounting member is entirely formed of a metal sheet and one electrode of the capacitor element as the composite component is electrically connected to the upper surface portion thereof, this composite component It is also possible to easily drop it to the ground via the mounting member.
