Abstract
A kind of electric heater convenient for wiring and repair, including bottom plate, cover plate, electrothermal tube, terminal box, it is characterised in that：The terminal box of electric heater and electrothermal tube upper and lower position exchange, terminal box top setting between two parties, and are horizontally arranged on electric heater bottom plate, ensure that connecting terminal is upward in terminal box.The utility model exchanges the terminal box of electric heater and electrothermal tube upper and lower position, terminal box top setting between two parties, and it is horizontally arranged on electric heater bottom plate, ensure that connecting terminal upward, is conducive to the specific patching operations of installation personnel, space is larger in terminal box, it is easily accessible, the operation difficulty that wiring can be mitigated significantly, completing the efficiency of wiring can significantly improve, and electric heater terminal box maintenance repair can also be facilitated to safeguard.
Description
Technical field
The utility model belongs to field of urban rail, and in particular to a kind of electricity being lifted on guest room chair framework adds
Hot device is used for passenger's warming.
Background technology
For subway project, is generally divided into seat and set electric heater for passenger's warming.And it is complete for electric heater
The electric heater being lifted under seat, terminal box are vertically installed on electric heater bottom plate.After lifting on the seat, in terminal box
Connecting terminal is to the right obliquely towards floor cloth.Shown in 1 cross-section diagram of attached drawing, terminal box 4 is vertically installed at electric heater bottom plate 1
On, 3 Wiring port 9 of electrothermal tube can be seen that the oblique direction of terminal box after electric heater is mounted on chair framework downward, from attached drawing 2
Lower right.Due to the liftoff plate cloth limited height of seat itself, along with terminal box position and orientation are unreasonable, therefore in electric heater
After installation, when being terminal box wiring, bolt 6 is first unclamped, (is only capable of opening certain angle, no around 5 Unscrew cover plate 2 of folding
Can dismounting remove), installation personnel face upward recumbency enter under seat by inboard, open connector cover 7 can just see connecting terminal 8,
It also needs to overcome the influence of postrotational cover plate simultaneously, entire wiring process is relatively difficult, time-consuming and laborious, inefficiency.
Invention content
The purpose of this utility model is the position and orientation by changing electric heater terminal box, to facilitate electric heater wiring
It is safeguarded with ordinary maintenance, to mitigate work difficulty, improves working efficiency.
To achieve the above object, the utility model provides a kind of electric heater convenient for wiring and repair, including bottom plate, cover
Plate, electrothermal tube, terminal box, it is characterised in that：Electrothermal tube is below terminal box, terminal box top setting between two parties, and horizontal peace
On electric heater bottom plate, ensure that connecting terminal is upward in terminal box.
Fire-proof and thermal-insulation material is pasted in the terminal box, is avoided temperature in terminal box excessively high, is caused cable or terminals
Son damage.
The utility model exchanges the terminal box of electric heater and electrothermal tube upper and lower position, terminal box top setting between two parties, and
And be horizontally arranged on electric heater bottom plate, ensure that connecting terminal upward, is conducive to the specific patching operations of installation personnel in terminal box,
Space is larger, easily accessible, can mitigate the operation difficulty of wiring significantly, completes the efficiency of wiring and can significantly improve, also can be square
Just the maintenance repair of electric heater terminal box is safeguarded.
Description of the drawings
Fig. 1 is former electric heater structure schematic diagram；
Fig. 2 is former electric heater scheme of installation；
Fig. 3 is the utility model electric heater structure schematic diagram；
Fig. 4 is the utility model electric heater scheme of installation.
Specific implementation mode
Refering to Fig. 3, Fig. 4, the guest room electric heater of the utility model is by bottom plate 1, cover plate 2, electrothermal tube 3, terminal box 4, folding
Page 5, screw 6 form.Terminal box is moved up and is horizontally arranged on bottom plate 1, and electrothermal tube Wiring port 9 is changed to upward downward, to
Ensure that connecting terminal is towards screw 6 in terminal box.After in this way in the case where electric heater is lifted on seat, terminal box is located proximate to seat
Right side edge, i.e. car body longitudinal center side.After unscrewing screw 6, rotation cover plate 5, opening connector cover 7, installation personnel is straight
Junction pair of wire connection terminals 8, and in seat right side edge, patching operations space is larger, and wiring is more convenient, and described connects
Fire-proof and thermal-insulation material 10 is pasted in wire box, avoids temperature in terminal box excessively high, and cable or connecting terminal is caused to damage.
Claims (2)
1. a kind of electric heater convenient for wiring and repair, including bottom plate, cover plate, electrothermal tube, terminal box, it is characterised in that：Electricity
