Abstract
The utility model relates to a composite material seal cover plate. The seal cover plate is composed of a metal cover plate and a rubber seal gasket, wherein the rubber seal gasket is tightly combined in a groove on a lower surface of the metal cover plate by compression molding, and the metal cover plate and the rubber seal gasket are integrated as a whole. Compared with the prior art, the composite material seal cover plate provided by the utility model is fastened to a housing of an electronic device by screws, together forming a sealed space for protecting the electronic device, so that the housing achieves a waterproof level of IPX7, and can dive in shallow water for a long time; the appearance is simple, and the requirement on the tightening torque of the screws is low; as the metal cover plate and the rubber seal gasket are integrated, the leakage face is reduced, so that the reliability is improved; and the composite material seal cover plate is fastened by screws, and has high operationality, being suitable for high-efficiency production cycle.
Description
Technical field
The utility model relates to the integral structure of metal cover board and rubber gasket, especially relates to a kind of composite material seal cover board.
Background technology
Present electronic element shell will reach the IPX7 classification of waterproof, and the general method that adopts has: 1. at the sealing surface gluing; 2. use gasket seal or O type circle; 3. to the electronic element sealing.
Though in sealing surface gluing good waterproof performance, need control gel quantity during gluing well.Glue is coated with to have lacked and may reach sealing effectiveness, is coated with glue many and can extrudes and influence outward appearance.And glue parches and needs certain hour, do not meet the High-efficient Production theory.
Using gasket seal or O type circle can is many designers' first-selection.The cover plate of this class hermetically-sealed construction generally has complicated profile and thicker wall thickness, and rigidity is very strong; Fastening with screw, and require screw that bigger screw-down torque is arranged.If the cover plate poor rigidity just produces deformation behind the screw-driving, influence sealing.When using gasket seal, if screw-driving moment is less, the decrement of gasket seal does not just reach the requirement of sealing especially.
Electronic element is carried out sealing handle (for example using the epoxide-resin glue encapsulation), the classification of waterproof of shell not only can reach IPX7, can also satisfy the requirement of long-time diving.If but the components and parts space of installing is bigger, just need to enclose more glue.Not only can't high efficiency production, also increased the weight of product simultaneously.
The utility model content
The purpose of this utility model is exactly to provide in order to overcome the defective that above-mentioned prior art exists that a kind of to make electronic element shell classification of waterproof reach more than the IPX7, improve reliability be the composite material seal cover board.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of composite material seal cover board is characterized in that the sealing cover plate is made of metal cover board and rubber gasket, and described rubber gasket is combined closely in the groove that the metal cover board lower surface arranges through die press technology for forming.
Described metal cover board and rubber gasket constitute integral structure.
Described metal cover board is provided with the spacing end face of screw-driving of control rubber gasket decrement, is separately positioned on four jiaos of metal cover board, prevents that the rubber gasket decrement is excessive and in use loses efficacy.
Offer screw hole on the spacing end face of described screw-driving.
On the sealing surface of described rubber gasket circular protrusion is set, plays the effect of labyrinth type sealing.
The middle part of described projection is provided with groove.
Compared with prior art, the shell of the utility model and electronic devices and components is by screw-driving, and the seal cavity of electronic devices and components is protected in common formation.This hermetically-sealed construction can reach the classification of waterproof of IPX7, and can dive under water for a long time in more shallow water, and profile is simple, and screw-driving moment requires little; Because its rubber gasket and metal cover board are integrated, have reduced leakage face, so can improve reliability.The composite material seal cover board uses screw fastening, workable, is fit to productive temp efficiently.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the sectional structure schematic diagram of A-A face among Fig. 1;
Decomposition texture schematic diagram when Fig. 3 is the utility model and electronic devices and components and shell installation.
Among the figure, 1 is that metal cover board, 11 is that the spacing end face of screw-driving, 12 is that screw hole, 2 is that rubber gasket, 21 is that circular protrusion, 22 is that groove, 3 is that shell, 4 is that electronic devices and components, 5 are screw.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
Embodiment
A kind of composite material seal cover board, its structure is shown in Fig. 1-2, the sealing cover plate is made of metal cover board 1 and rubber gasket 2, and metal cover board 1 and rubber gasket 2 constitute integral structure, and rubber gasket 2 is combined closely in the groove that metal cover board 1 lower surface arranges through die press technology for forming.
Be provided with the spacing end faces 11 of screw-driving of control rubber gasket decrement at metal cover board 1 four jiaos, prevent that the rubber gasket decrement is excessive and in use lost efficacy, offer screw hole 12 on the spacing end face 11 of screw-driving.At the spacing end face 11 of the Position Design screw-driving of screw hole 12, can effectively control the decrement of rubber gasket 2.If the decrement of rubber gasket 2 is excessive, is being subjected under the situation of high temperature elastomeric material just can't recover elastic force and was losing efficacy.
Sealing surface at rubber gasket 2 arranges circular protrusion 21, and the middle part of circular protrusion 21 is provided with groove 22, and this makes rubber gasket 2 transfer linear sealing to from face sealing, and the required screw-down torque of the screw of composite material seal cover board is littler relatively.The circular protrusion 21 of rubber gasket 2 and groove 22 constitute the labyrinth type hermetically-sealed construction, have increased the reliability of waterproof.
Assembly structure of the present utility model as shown in Figure 3.Electronic devices and components 4 are installed in the shell 3, and shell 3 and composite material seal cover board are fastening by screw 5, and the sealing surface of shell 3 seals by the rubber gasket 2 on the composite material seal cover board, thereby reaches the IPX7 classification of waterproof.
