この考案はガス検出素子用ホールダの改良に関

がほとんどである。 Gas detection elements include those in which a semiconductor material is provided on an insulator with a pair of electrodes and sintered, and those in which an electrode and a heater-cum-electrode are embedded in a semiconductor material and sintered. Both gas detection elements are fragile and inconvenient to handle. For this reason, in most cases, the gas detection element is placed in a holder in advance, and the holder is inserted into a socket provided on a printed circuit board.

２間が短絡状態となつてしまう問題がある。 By the way, the conventional gas detection element holder is
As shown in FIGS. 1 and 2, a plurality of metal terminals 2 are provided through an insulating base 1 made of phenolic resin or the like at intervals, and a gas detection element 6 is attached to the head of each terminal 2. A lead wire 7 to which a pair of electrodes is connected and a lead wire 8 of a heater for heating the gas detection element 6
is attached by welding or the like to support the gas detection element 6. As shown in FIG. 1, an explosion-proof wire mesh 9 is attached to the base 1 with a ring 10 made of metal or the like. The surface of the base 1 of such a holder on which the gas detection element 6 is attached is constantly exposed to the outside air through the wire mesh 9, so dust containing moisture and oil accumulates and accumulates on each surface. There is a problem in that the insulation between the terminals 2 deteriorates and the terminals 2 become short-circuited.
この考案は以上の点にかんがみ、絶縁性基台に
ガス検出素子のリード線の取り付けのため貫通し

より汚染されても各端子間の絶縁性が十分に得ら
れるようしたものである。 In consideration of the above points, this idea is based on the idea that each side wall of a plurality of metal terminals that protrude through the insulating base for attaching the lead wires of the gas detection element to the insulating base is made of an insulator that is integrated with the insulating base. By coating, it is possible to obtain sufficient creepage distance between each terminal with a simple structure, and even if the surface of the base is contaminated by dust accumulation, sufficient insulation between each terminal can be obtained. It is something.
以下この考案の１実施例を第３図，第４図によ

５によつて被覆されて構成される。 In Figures 3 and 4, 1 is an insulating base made of phenolic resin, etc., 2 is a plurality of terminals provided through the base 1, and each terminal 2 is a base for attaching a gas detection element. A portion of the side wall 3 protruding from the base 1, except for the head 4, is covered with an insulator 5 integral with the base 1.

端子間の絶縁性を十分に得られる効果がある。 As explained in the above embodiment, the gas detection element holder of this invention separately insulates each side wall of a plurality of metal terminals that protrude through an insulating base in order to mount a gas detection element. Since it is covered with an insulator that is integrated with the base,
Compared to conventional gas detection element holders, the creepage distance between each terminal can be sufficiently increased with a simple structure without increasing the size of the holder, which prevents the surface of the insulating base from being contaminated by dust. This has the effect of providing sufficient insulation between each terminal.
