Embodiment
A kind of wire fixing device, comprises end cap 1, service cover 5 and fixture.
As shown in Fig. 3-6, there is wire casing in the arranged outside of end cap 1, wire casing and end cap are integrated, and in the present embodiment, wire casing comprises shaped form wire casing 10 and the linear wire casing 14 crossing with shaped form wire casing 10, and shaped form wire casing is similar to anti-S shape.User can, at linear wire casing and two middle choice for uses of shaped form wire casing, in other embodiments, also can only arrange shaped form wire casing.
On end cap, be provided with entrance hole 7 and make power line 4 enter water heater inside from water heater outside, one end of shaped form wire casing 10 is facing to entrance hole 7.As shown in Figure 6, power line 4 is installed in shaped form wire casing 10, it is in order to ensure that power line pulling capacity meets standard-required that bending shaped form wire casing 10 is set, the frictional force of power line and cell wall is increased, ensure can not occur the situation of power line and the disconnection of water heater internal electric part joint under certain pulling capacity.
As shown in Figure 4, be also provided with the linear wire casing 14 crossing with shaped form wire casing 10 on end cap, one end of linear wire casing 14 is facing to entrance hole 7.These linear wire casing 14 designs are for a kind of power line fixing means is provided more, in the situation that use curve shape wire casing 10 is not installed power line, can use linear wire casing that power line is installed.
The cell wall medial surface of shaped form wire casing is male and female face, as shown in Figure 5, in the present embodiment, the cell wall medial surface of shaped form wire casing 10 is provided with salient point 13, salient point slot length direction along the line is arranged and each salient point has interval each other, and salient point makes wire casing cell wall medial surface form male and female face.
This bump design is power line denaturation headspace, in the time of water heater working, when its power line heating is expanded, in the interval between the inflatable embedding salient point 13 of its crust.And in the time that water heater is not worked at ordinary times, power line does not generate heat, and expanding still can contact with salient point 13 increases its frictional force.In other embodiments, salient point also can be replaced by fin or other bulge-structures.
As shown in Figure 3,4, on the end cap between shaped form wire casing 10 head and the tail, be provided with screw 9, screw 9 is located at shaped form wire casing 10 sides.
As shown in Figure 7,8, be provided with press fit device in service cover inner side, in the service cover 5 between press fit device 11 head and the tail, screw 12 be set, this screw 12 is corresponding with screw 9 positions on aforementioned end cap 1, in the time that service cover 5 covers on end cap, and screw 12 and screw 9 correspondences.
As shown in Fig. 9,10, service cover 5 is fixed by fixture with end cap 1, in the present embodiment, adopts a screw 8 to fix service cover 5 and end cap 1 as fixture.Screw 8 is fixing with screw 9 after through screw 12, thereby service cover 5 and end cap 1 are fixed.
As shown in Figure 7,8, be provided with press fit device 11 in service cover 5 inner sides, press fit device 11 is integrated with service cover 5, and press fit device 11 comprises multiple risers, gap arrangement between multiple risers.
Press fit device also comprises connecting plate, and riser middle part or the termination of multiple parallel gap arrangement link together by connecting plate, and each riser and connecting plate contact cooperation across frame in the top of wire casing and the cell wall top of wire casing.Connecting plate increases the stability of riser, and because the shaped form wire casing in wire casing is bending, therefore in specific position, connecting plate also can play the effect of compacting power line.In the present embodiment, the termination of the riser of multiple parallel gap arrangement links together by connecting plate.
After service cover 5 is fixing with end cap 1, press fit device is pressed on wire casing and with the cell wall top of wire casing and contacts cooperation, the groove that wire casing was originally open state pushes up by press fit device block, press fit device is fixed on power line in wire casing, to prevent that it from deviating from, the riser of press fit device is all crossing with shaped form wire casing 10 and linear wire casing 14, ensure no matter be the interior installation power line of shaped form wire casing 10 or linear wire casing 14, press fit device 11 all can be suppressed power line can not deviate from it from wire casing.
In the present embodiment, wire casing comprise two can choice for use linear wire casing and shaped form wire casing, if the shape that press fit device arranges completely with the trend of shaped form wire casing, the global shape of shaped form wire casing has improved the manufacture difficulty of press fit device.Therefore, for simplified manufacturing technique, no matter use which wire casing, for press fit device can be pressed on wire casing fully, press fit device is made the shape of squarish.The shape of its shape of press fit device and linear wire casing and shaped form wire casing entirety region is similar and adapt, be that the length of press fit device and the length of linear wire casing and shaped form wire casing region adapt, the width of the width of press fit device and linear wire casing and shaped form wire casing region adapts.Like this, press fit device can be suppressed most wire casing, avoids occurring that press fit device can not suppress the phenomenon of the power line in wire casing and occur.
In the present embodiment, can better fix service cover and end cap in order to make a screw, and can make the press fit device in service cover more securely be pressed on wire casing, service cover screw 12 be arranged at the centre of press fit device, press fit device is divided into two parts, it is square that two parts are respectively two classes of size, and screw can make better two parts all wire casing be had to corresponding pressure between two parts.
In other embodiments, if shaped form wire casing is only set, for press fit device can be pressed on wire casing fully, press fit device has been made the shape of squarish.The shape of its shape of press fit device and shaped form wire casing entirety region is similar and adapt, and the length of the length of press fit device and shaped form wire casing region adapts, and the width of the width of press fit device and shaped form wire casing region adapts.
A kind of wire fixing device of the utility model, at end cap arranged outside wire casing, power line from being installed in wire casing water heater after the entrance hole on being arranged on end cap enters water heater, after service cover is covered on end cap and utilizing a screw fixing, the press fit device that is arranged on service cover inner side is pressed on the wire casing of end cap and contacts cooperation with the cell wall top of wire casing, the groove that wire casing was originally open state pushes up by press fit device block, thereby power line is secured in a press, prevents that power line from deviating from groove.Power line press fit device and service cover integrate, and adopt a screw service cover and end cap can be fixed and then power line is fixed, thereby have saved screw number and station is installed, and have improved operating efficiency, have saved production cost.
Embodiment in above-described embodiment can further combine or replace; and embodiment is described preferred embodiment of the present utility model; not design of the present utility model and scope are limited; do not departing under the prerequisite of the utility model design philosophy; the various changes and modifications that in this area, professional and technical personnel makes the technical solution of the utility model, all belong to protection range of the present utility model.
