Description

Solenoid valve binding tube anti-oil-leakage structure

Technical field

The utility model relates to a kind of solenoid valve binding tube anti-oil-leakage structure, especially refer to that a kind of lead that makes first and second heat-shrink tube and wiring and electrical inserting terminal reaches the effect of effective sealing, and then prevent mechanical cycles fluid from oozing out and cause the damage of circuit board, tool to promote circuit board working life by the electrical inserting terminal side.

Background technique

Press, general common, as the Taiwan patent gazette, announce " many stamens electrocardio hot line water joint " a case of No. 482365, it is to be applied in engaging of the electrocardio of stamen more than hot line end and a wire termination, its structure characteristics includes:

One conducting element, have one first end and connect second end of this first end, this first end is needle-like and inserts in this electrically-heated-wire end with this electrically-heated-wire axis direction, makes this first end electrically contact the stamen heart of this electrically-heated-wire, and this second end then can electrically connect this wire termination;

One waterproof joint element, comprise a heat-shrink tube and and coat the Waterproof glue line of this heat-shrink tube internal face, make this waterproof joint element cover be overlying on this electrically-heated-wire end, this conducting element and this wire termination outside, and make this waterproof joint element be heated aftershrinkage and fix the relative position of this electrically-heated-wire end, this conducting element and this wire termination.

Though above-mentioned " many stamens electrocardio hot line water joint ", can make engaging of " electrically-heated-wire end " and " wire termination ", but, because must be provided with one " conducting element " on this case concrete structure is necessary composed component, to be connected in the two end part of desiring the closing line body, coat with the waterproof joint element, it is used because of the electrically-heated-wire that is applicable to many stamens core type, so its technical " conducting element " is indispensable composed component again.

And the design focal point of this case is reached the standard grade and is known from experience the shortcoming of leakage of oil for improving common solenoid valve configurations, because common traditional electrical magnet valve is textural, its lead one end is for being connected on solenoid valve, and the solenoid valve use occasion may be infiltrated in the mechanical cycles oil, the end that extends in this lead is set to the terminal that plug-in is used, and solenoid valve its have a straight-line axle center, under the normality because of capillary phenomenon or because of the straight line motion effect repeatedly of this axle center, to cause this mechanical cycles fluid following the internal void of lead and terminal that seepage is used for plug-in is distolateral, and then with moistening to related elements such as circuit boards, and cause the damage of circuit board feature.Thereby improve that to make the unlikely fluid that outwards leaks out of lead of solenoid valve be the purpose of this utility model.

Summary of the invention

Therefore, main purpose of the present utility model is to be to provide a kind of solenoid valve binding tube anti-oil-leakage structure, can make the stamen line of solenoid valve one terminated line and the stamen line joint at the close electrical inserting terminal place of wiring extending end, by first and second heat-shrink tube stamen line and wiring are distinguished tight enclosing, reach effective sealing stamen line and connect the effect of an interlayer, and then prevent that the mechanical cycles fluid in the solenoid valve environment of living in from being oozed out by the electrical inserting terminal side, and cause the damage of circuit board.

In order to achieve the above object, the utility model is a kind of solenoid valve binding tube anti-oil-leakage structure, it is to comprise that one has coil, movable stem, wiring and solenoid valve body that electrical inserting terminal constituted, and this electrical inserting terminal is can be for being plugged on the circuit board, wherein the stamen line of the stamen line of this wiring and electrical inserting terminal lead is connected in scolding tin or the stamen line mode that tangles or stamp terminal of twisting thread, and the joint is to be arranged with first heat-shrink tube; And this wiring and electrical inserting terminal lead joint are arranged with second heat-shrink tube again and seal fully, and make and form the obstructed state that blocks between two first and second heat-shrink tubes; By this, can make in the armoured conduit of solenoid valve to reach the effect of effective sealing, and then prevent that the mechanical cycles fluid in the solenoid valve body from being oozed out by electrical inserting terminal, and cause the damage of circuit board.

Embodiment

Seeing also " Fig. 1～shown in Figure 5 ", is the utility model first embodiment's schematic representation.As shown in the figure: the utility model is a kind of solenoid valve binding tube anti-oil-leakage structure, can prevent that the mechanical cycles fluid in the solenoid valve body from being oozed out by electrical inserting terminal, and cause the damage of circuit board.And this solenoid valve binding tube anti-oil-leakage structure its be to comprise: a solenoid valve body 1, be provided with a coil 11 in this

solenoid valve body

1, and 11 of this coils are to be provided with a movable stem 12, and a wiring 13 (as shown in Figure 1) that connects electrical inserting terminal 15 leads 14 is set on this solenoid valve body 1, and this electrical inserting terminal 15 is can be for being plugged on the circuit board (ignoring), wherein, but the stamen line 131 of this wiring 13 is engaged with the stamen line 141 joint mat tradition scolding tin technology of electrical inserting terminal 15 leads 14, (ginseng Fig. 4 in scolding tin bonding point 5, Fig. 5) outside is to be arranged with first heat-shrink tube 2, and this first heat-shrink tube 2 is to can be a heat-shrink tube that contains glue, by being given, heat-shrink tube 2 after the heat baking its complete condensation is cohered, the inside of its heat-shrink tube 2 is because of having the hot melt colloid, and therefore the appearance in the stamen line (131) (141) that is engaged can reach the effect of insulation fully.And be arranged with second heat-shrink tube 3 again in lead 14 joints of this wiring 13 and electrical inserting terminal 15 ends, and this second heat-shrink tube 3 can be a heat-shrink tube (as Fig. 2, Fig. 3, Fig. 4, shown in Figure 5) that contains glue equally, the interior table portion of the appearance portion of its first heat-shrink tube 2 and second heat-shrink tube 3 is cohered because of the hot melt colloid to be sealed up, and the rear and front end of second heat-shrink tube 3 covers with wiring 13 and lead 14 are outer that rubber is firm to be combined respectively, and what prevent that moisture content from invading and fluid oozes out improves in conjunction with effect.
