But the structure of traditional motor Jiao Gai is easy in use so that the component under Jiao Gai is stained with carbon dust and draws
Short circuit is played, the safety problem in motor use is caused.
Utility model content
The main purpose of the utility model is to provide a kind of direct current generator Jiao Gai, can protect PTC isolation carbon dust contacts,
It effectively prevent PTC short-circuit in use, solves the safety problem of motor application, can effectively solve asking in background technology
Topic.
To achieve the above object, the technical solution that the utility model is taken is：
A kind of direct current generator Jiao Gai, including glue lid ontology, the glue lid ontology upper edge central axis offer bearing hole, institute
It states and is equipped with spring stack, carbon brush slot, terminal groove, inductance slot and PTC protection caps on glue lid ontology along the vertical direction.
Preferably, the PTC protection caps are closed flute profile.
Preferably, the lateral cross section of the PTC protection caps is rectangle.
Preferably, the area of lateral cross section of the area of the lateral cross section of the PTC protection caps equal to or more than PTC.
Preferably, the upside of the carbon brush slot and left and right either side offer opening.
Preferably, the direct current generator Jiao Gai of the utility model further includes inductance, angle and the inductance of the inductance slot
Angle is the same.
Preferably, the left side of the glue lid ontology is equipped with the spring stack, the carbon brush slot, the end successively from the bottom to top
Pilot trench and the inductance slot, the right side of the glue lid ontology are equipped with the spring stack successively from the bottom to top, the carbon brush slot, described
Inductance slot and the terminal groove, the PTC protection caps are set between the left side inductance slot and the right side terminal groove.
Compared with prior art, the direct current generator Jiao Gai of the utility model, including glue lid ontology, glue lid ontology upper edge center
Axis offers bearing hole, is equipped with spring stack, carbon brush slot, terminal groove, inductance slot and PTC protections on glue lid ontology along the vertical direction
Lid.Then, glue lid ontology is equipped with PTC protection caps, realizes that protection PTC isolation carbon dusts avoid that short circuit occurs, avoids using process
It is middle because of PTC "Fail-safe" problems.
Description of the drawings
Fig. 1 is the overall structure diagram of the utility model direct current generator Jiao Gai.
Specific implementation mode
To make the technical means, creative features, achievement of purpose, and effectiveness of the utility model be easy to understand, below
In conjunction with specific implementation mode, the utility model is expanded on further.
Referring to Fig. 1, the direct current generator glue lid 100 of the utility model, including glue lid ontology 10, in 10 upper edge of glue lid ontology
Mandrel line offers bearing hole (not shown), and spring stack 12, carbon brush slot 13, terminal are equipped with along the vertical direction on glue lid ontology 10
Slot 14, inductance slot 15 and PTC protection caps 16.Then, glue lid ontology 10 is equipped with PTC protection caps 16, realizes that carbon is isolated in protection PTC20
Powder avoids that short circuit occurs, and avoids in use because of PTC20 "Fail-safe" problems.Specifically, as follows：
Wherein, the lateral cross section of PTC protection caps 16 is rectangle.It is similar to the shape of PTC20, preferably pasted with PTC20
Close, structure is more reasonable, certainly, in other embodiments, the shapes of PTC protection caps 16 can according to specific use demand and
It neatly designs, therefore this is no longer going to repeat them.
Compared with the superior, PTC protection caps 16 are closed flute profile.Further carbon dust is isolated in preferably protection PTC20, effectively prevent
PTC20 contacts short circuit caused by carbon dust.
Selectively, the area of lateral cross section of the area of the lateral cross section of PTC protection caps 16 equal to or more than PTC20.
So that PTC20 is preferably inserted into PTC protection caps 16.
Compared with the superior, the upside of carbon brush slot 13 and left and right either side offer opening 131.Use can preferably be met to want
It asks.Certainly, in other embodiments, the shape of carbon brush slot 13 can neatly be designed according to specific use demand, therefore
This is no longer repeated one by one.
Selectable, the direct current generator glue lid 100 of the utility model further includes inductance (not shown), the angle of inductance slot 15
Degree is as inductance angle.So that inductance facilitates installation, inductance foot can be more fixed on direct current generator glue lid 100, and be saved
The inner spaces Jiao Gai are saved.
The left side of glue lid ontology 10 from the bottom to top successively be equipped with spring stack 12, carbon brush slot 13, terminal groove 14 and inductance slot 15,
The right side of glue lid ontology 10 is equipped with spring stack 12, carbon brush slot 13, inductance slot 15 and terminal groove 14, PTC protections successively from the bottom to top
Lid 16 is set between left side inductance slot 15 and right-hand end pilot trench 14.Structure is more reasonable compact, certainly, spring stack 12, carbon brush slot
13, the position of terminal groove 14, inductance slot 15 and PTC protection caps 16 on glue lid ontology 10 can according to specific use demand and
It neatly designs, therefore this is no longer going to repeat them.
Compared with prior art, the direct current generator glue lid 100 of the utility model, including glue lid ontology 10, glue lid ontology 10
Upper edge central axis offers bearing hole, and spring stack 12, carbon brush slot 13, terminal groove are equipped with along the vertical direction on glue lid ontology 10
14, inductance slot 15 and PTC protection caps 16.Then, glue lid ontology 10 is equipped with PTC protection caps 16, realizes that carbon dust is isolated in protection PTC20
It avoids that short circuit occurs, avoids in use because of PTC20 "Fail-safe" problems.
