Abstract
A terminal plate is formed with a wide portion and a narrow portion. The wide portion, to be insert-molded by a housing of a synthetic resin, is opened by an elongate blank hole having an inner peripheral surface parallel with a side shape thereof, thereby forming two divisional parts on the both sides thereof. The divisional part is given by a width s1 narrower than a width s2 of the narrow portion, wherein the total width (s1×2) of the two divisional parts is made equal to the width s2 of the narrow portion. Grooves can be formed on the main and back surfaces of the divisional parts.
Claims3
A connector device comprising:
- a housing made of a synthetic resin;
- and
- a terminal plate made of a metal having an intermediate portion insert-molded in the housing and both ends projecting at different end surfaces of the housing;
- wherein an insert-mold part of the terminal plate is opened with a blank hole having an inner peripheral surface parallel with a side shape of the insert-mold part, to have divisional parts divided by the blank hole,
- wherein the divisional parts are formed narrower in width than the both ends,
- wherein the blank hole has an elongated shape in a lengthwise direction given in parallel with a lengthwise direction of the terminal plate, and
- wherein a plurality of grooves are formed extending in a direction to intersect the hole and perpendicular to the lengthwise direction of the terminal plate, on main and back surfaces of the divisional parts.
An EGR sensor comprising:
- a housing made of a synthetic resin;
- an operating shaft slidably attached on the housing;
- position detecting means for detecting a position of the operating shaft;
- and
- a terminal plate made of a metal having an intermediate portion insert-molded in the housing and both ends projecting at different end surfaces of the housing;
- wherein an insert-mold part of the terminal plate is opened with a blank hole having an inner peripheral surface parallel with a side shape of the insert-mold part, to have divisional parts divided by the blank hole,
- wherein the divisional parts are formed narrower in width than the both ends,
- wherein the blank hole has an elongated shape in a lengthwise direction given in parallel with a lengthwise direction of the terminal plate, and
- wherein one to a plurality of grooves are formed extending in a direction, to intersect the hole and perpendicular to the lengthwise direction of the terminal plate, on main and back surfaces of the divisional parts.
