Abstract
The utility model discloses a silicon rubber sleeve of a wire of an elevator control board. The silicon rubber sleeve comprises a first opening part and a second opening part which are connected with each other, the first opening part is in interference fit with a backboard through hole, layer-shaped corrugations are formed on the joint of the second opening part and the first opening part. The silicon rubber sleeve with corrugations enables the sleeve to have better sealing performance and lower cost by means of the elasticity thereof and is more convenient to mount, and furthermore, corrugations are formed between the first opening part and the second opening part, so that the second opening part is capable of turning to comply with the bending direction of the wire to protect the wire.
Description
Technical field
The utility model relates to a kind of elevator control panel electric wire silicone envelope, belongs to elevator field.
Background technology
Elevator control panel is arranged on each floor, calls and calls out elevator to designated floor for passenger, is the vitals of controlling elevator operation and man-machine interaction.Elevator control panel is arranged on backboard, protection is provided and is supported by backboard.On backboard, offer various electric wires that through hole is convenient to circuit card through backboard.But this through hole also makes back of circuit board be exposed in air.As everyone knows, back of circuit board is all the solder joint of electronic component, and at the higher regional solder joint of humidity very easily by short circuit or oxide etch.On the through hole of existing backboard, be all provided with metal big envelope, this big envelope is fixed on through hole by screw thread, so not only can allow electric wire pass through but also can protective circuit plate.But not only the high assembling of cost is complicated for this metallic envelope, and electric wire is not flexible, and sealing property is also unsatisfactory.
Utility model content
Utility model object: the utility model proposes a kind of elevator control panel electric wire silicone envelope, good seal performance easy to assembly, electric wire is flexible, simultaneously cheap.
Technical scheme: the technical solution adopted in the utility model is a kind of elevator control panel electric wire silicone envelope, described big envelope has the first peristome and the second peristome that are interconnected, described the first peristome and backboard through hole interference fit, the second peristome and the first peristome intersection are provided with the ripple of stratiform.
As a kind of improvement of the present utility model, described the first peristome diameter is greater than the second peristome.
Beneficial effect: the utility model proposes a kind of employing and be with ripply silica gel material big envelope, the elasticity that it utilizes silica gel self, makes big envelope possess better sealing property and lower cost, and to install also more convenient simultaneously.On the other hand, between the first peristome and the second peristome, ripple is set, makes the second peristome there is turning function, can comply with the bending direction of electric wire, played the effect of protection electric wire.
Accompanying drawing explanation
Fig. 1 is assembly drowing of the present utility model;
Fig. 2 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, further illustrate the utility model, should understand these embodiment and only be not used in restriction scope of the present utility model for the utility model is described, after having read the utility model, those skilled in the art all fall within the application's claims limited range to the modification of various equivalents of the present invention.
As shown in Figure 1, backboard 2 is provided with the through hole 3 that allows electric wire pass through.Be sleeved on described through hole 3 to silicone envelope 1 interference fit of the present embodiment, through hole 3 is sealed prevent that steam from entering through hole 3 completely.With respect to existing metallic envelope, due to the elasticity of silica gel self, make silicone envelope better in the condition lower seal performance of interference fit, and install convenient quick.
Claims (2)
1. an elevator control panel electric wire silicone envelope, it is characterized in that: described big envelope has the first peristome and the second peristome that are interconnected, described the first peristome and backboard through hole interference fit, the second peristome and the first peristome intersection are provided with the ripple of stratiform.
2. elevator control panel electric wire silicone envelope according to claim 1, is characterized in that: described the first peristome diameter is greater than the second peristome.
