Claims (6)
- 표면장착에 적합한 접속 도선(4 및 5)을 가지고, 함께 접속가능한 두개의 하우징 부분(2 및 3)으로 구성되며, 접속도선은 절연된 방식으로 하우징의 한 부분(3)을 통과하고 최소한 하나의 다른 접속 도선(5a 및 5b)이 상기 하우징 부분으로 접속되는, 밀봉된 박스 모양 또는 슬리브 모양의 압전 공진기 하우징(1)에 있어서, 하우징(1)은 은 밑면에 대해 경사를 이루는 평면에서, 함께 접속가능한 상부 및 하부 하우징 부분(2 및 3)으로 분할되고, 한쪽 끝이 절연된 압전 공진기의 접속도선(4a 및 4b)은 반대쪽에 위치한 최소한 하나의 다른 접속 도선이 접속된 하우징 부분을 통과하며, 압전 공진기(8)는 하부 하우징 부분(3)에 장착되는 것을 특징으로 하는 압전 공진기 하우징.
- 제1항에 있어서, 상기 평면은 상기 하우징을 대각선으로 가로지르는 것을 특징으로 하는 압전 공진기 하우징.
- 제1항에 있어서, 함께 접속가능한 두개의 하우징 부분(2 및 3)의 가장자리는 플랜지(9)로서 형성되는 것을 특징으로 하는 압전 공진기 하우징.
- 제2항에 있어서, 두개의 하우징 부분의 가장자리가 함께 용접되는 것을 특징으로 하는 압전 공진기 하우징.
- 제1항에 있어서, 하부 하우징 부분(3)에 접속된 접속도선(5a 및 5b)은 상기 하우징 부분의 일부로서 형성되는 것을 특징으로 하는 압전 공진기 하우징.
- 제1항에 있어서, 상기 소자(8)는 하부 하우징 부분(3)에 장착되어 상기 하우징 부분의 밑면에 평행인 하우징 부분의 가장 아래 측면을 향해 확장하는 것을 특징으로 하는 압전 공진기 하우징.
