ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a high-voltage connector for use with electronic apparatuses driven nowadays with higher voltages, and more particularly to a connector used with high-voltage power source circuits that will activate the back-light devices in such liquid crystal displays as built in certain personal computers, wherein the circuits may be some printed inverter circuit boards that have recently been made smaller and smaller in size and in height.
2. Prior Art
The current notebook type personal computers, for example, have been required to comprise as large liquid crystal displays as possible within a de-limited dimension which the computer body frames afford. Such enlarge displays have necessitated higher voltages amounting to 1000-1400 volts or so to activate the back-light illuminators. Since the printed inverter boards, viz., the power sources, for feeding electric energy to the back-lights have usually been set in those body frames, such larger displays have reduced the surface mount areas allotted to the printed inverter boards, causing same to be made smaller in size.
Connectors each electrically connecting the smaller-sized printed inverter board to the back-light device have thus to be smaller and nevertheless resistant to high voltages. The present applicant has therefore filed a patent application for an invention as disclosed in the Japanese Laying-Open Gazette No. 10-172649. In this preceding invention, linear distance and spatial distance between the contacts in the connector were increased so that it could withstand high voltages.
SUMMARY OF THE INVENTION
However, the current market more strongly demands the notebook type personal computers rendered much lighter in weight and much thinner in shape. An object of the present invention that was made to meet these requirements is therefore to provide a high-voltage connector not only assuring the shortened linear and spatial distances between the contacts but also having a reduced overall height, by improving the connector proposed in the Gazette No. 10-172649.
In order to achieve this object, a high-voltage connector that is provided herein does consist of a male assembly as one of the mating parts of the connector and a female assembly as the other mating part, the male assembly comprising a first insulating housing and a pair of pin contacts held therein. Each of the pin contacts consists of a contacting pin body extending in parallel with a center line of the insulating housing and facing an opening thereof, and a lead continuing from the pin body and exposed outside the housing to form a solderable portion capable of being soldered to a printed circuit board. The leads are bent sideways in opposite directions such that the solderable portions are spaced from each other a distance greater than that between the pin bodies. The male assembly further comprises an internal partition disposed in the housing and intermediate the pin bodies, and having a free end that is located closer to the opening of the housing than free ends of the pin bodies are. On the other hand, the female assembly comprises a second insulating housing and a pair of socket contacts held therein and securable on respective wire ends. The second housing, that is insertable into the first housing through the opening thereof so as to cause the socket contacts to fit on the respective pin bodies, has a recess fittable on the partition such that a pair of cylindrical compartments are formed in the second housing to render it bifurcated and to accommodate the respective socket contacts isolated from each other. Characteristically, those socket contacts having respective lances are laid on their sides (in other words, “upside sideways”) such that the lances are respectively disposed close to opposite side walls of the second housing, wherein the side walls have formed therein latch means for holding the lances in place.
