The utility model provides a pair of membrane switch pin end protection architecture that pegs graft, the reinforcing plate is through gluing the back that the material pasted and locate the base film, glues the material and is short in the reinforcing plate at the ascending length of grafting side in the ascending length of grafting side for base film and reinforcing plate form certain space in one side of keeping away from the end of pegging graft, so that the base film can take place a quantitative bending in the small-range, avoid pin end to stretch hard and lead to being connected with PCBA and drop, also make things convenient for the field installation simultaneously.
Description
Technical Field
The utility model relates to a film switch technical field, in particular to pin end grafting protection architecture of film switch.
Background
The membrane switch is an operation system integrating a key function, an indicating element and an instrument panel. The structure is precise, the appearance is beautiful, the sealing performance is good, and the device has the characteristics of moisture resistance, long service life and the like. The method is widely applied to the fields of electronic communication and electronic measurement instruments, industrial control, medical equipment, automobile industry, intelligent toys, household appliances and the like.
The pin end of the membrane switch is soft in texture, and a reinforcing plate is usually required to be arranged on the back surface of the base membrane so as to form a plug connection with the PCBA. However, in the actual use process, the reinforcing plate is hard, the base film is soft, when the reinforcing plate is completely attached to the back surface of the base film, the insertion part of the base film cannot be bent under the action of the reinforcing plate, so that the pin is hard and stretchable, is easy to fall off from the PCBA, and is inconvenient to install on site.
Therefore, to overcome the defects in the prior art, it is necessary to design a pin-end plugging protection structure of a membrane switch to solve the above problems.
SUMMERY OF THE UTILITY MODEL
In order to overcome the defects in the prior art, the utility model aims to provide a pin end plugging protection structure of a membrane switch.
In order to achieve the above objects and other related objects, the present invention provides a technical solution: the utility model provides a membrane switch pin end protection architecture of pegging graft, includes the base film, the positive printing of base film has electrically conductive silver thick liquid layer, the base film back is pasted and is equipped with the reinforcing plate, the reinforcing plate is located through gluing the material subsides the back of base film, glue the ascending length of material in grafting direction and be short in the ascending length of reinforcing plate in grafting direction.
The preferable technical scheme is as follows: and a carbon ink layer is printed on the conductive silver paste layer.
The preferable technical scheme is as follows: the base film and the reinforcing plate are both made of PET.
Because of the application of the technical scheme, the utility model discloses the beneficial effect who has does:
the utility model provides a pair of membrane switch pin end protection architecture that pegs graft, the reinforcing plate is through gluing the back that the material pasted and locate the base film, glues the material and is short in the reinforcing plate at the ascending length of grafting side in the ascending length of grafting side for base film and reinforcing plate form certain space in one side of keeping away from the end of pegging graft, so that the base film can take place a quantitative bending in the small-range, avoid pin end to stretch hard and lead to being connected with PCBA and drop, also make things convenient for the field installation simultaneously.
Drawings
Fig. 1 is a schematic cross-sectional view of the present invention.
In the above figures, 1, a base film; 2. a conductive silver paste layer; 3. a reinforcing plate; 4. glue material; 5. a carbon ink layer.
Detailed Description
The following description is provided for illustrative purposes, and other advantages and features of the present invention will become apparent to those skilled in the art from the following detailed description.
Please refer to fig. 1. It should be understood that, in the description of the present invention, it should be noted that the directions or positional relationships indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. are based on the directions or positional relationships shown in the drawings, or the directions or positional relationships that the products of the present invention are usually placed when they are used, and are only for the convenience of describing the present invention and simplifying the description, but not for indicating or implying that the indicated device or element must have a specific direction, be constructed and operated in a specific direction, and therefore, should not be construed as limiting the present invention. Furthermore, the terms "first," "second," "third," and the like are used solely to distinguish one from another and are not to be construed as indicating or implying relative importance. The terms "horizontal", "vertical", "overhang" and the like do not imply that the components are required to be absolutely horizontal or overhang, but may be slightly inclined. For example, "horizontal" merely means that the direction is more horizontal than "vertical" and does not mean that the structure must be perfectly horizontal, but may be slightly inclined.
In the description of the present invention, it should be further noted that, unless otherwise explicitly stated or limited, the terms "disposed," "mounted," "connected," and "connected" are to be construed broadly and may include, for example, a fixed connection, a detachable connection, an integral connection, a mechanical connection, an electrical connection, a direct connection, an indirect connection via an intermediate medium, and a connection between two elements. The specific meaning of the above terms in the present invention can be understood as a specific case by those skilled in the art.
Example (b):
as shown in fig. 1, for the utility model provides a membrane switch pin end grafting protection architecture, including base film 1, base film 1 openly prints and has electrically conductive silver thick liquid layer 2, and base film 1 back subsides are equipped with reinforcing plate 3.
Wherein, reinforcing plate 3 pastes the back of locating base film 1 through gluing material 4, glues the length of material 4 in the grafting direction and is shorter than reinforcing plate 3 length in the grafting direction. This design can make base film 1 and reinforcing plate 3 form certain space in the one side of keeping away from the end of pegging graft to base film 1 can take place a certain amount of bending in the small range, avoids pin end hard to stretch to lead to being connected with PCBA and drops, also makes things convenient for the field installation simultaneously.
In addition, the conductive silver paste layer 2 is printed with a carbon ink layer 5 for protecting the conductive silver paste layer 2.
The base film 1 and the reinforcing plate 3 are both made of PET.
Therefore, the utility model has the advantages of it is following:
the utility model provides a pair of membrane switch pin end protection architecture that pegs graft, the reinforcing plate is through gluing the back that the material pasted and locate the base film, glues the material and is short in the reinforcing plate at the ascending length of grafting side in the ascending length of grafting side for base film and reinforcing plate form certain space in one side of keeping away from the end of pegging graft, so that the base film can take place a quantitative bending in the small-range, avoid pin end to stretch hard and lead to being connected with PCBA and drop, also make things convenient for the field installation simultaneously.
The above embodiments are merely illustrative of the principles and effects of the present invention, and are not to be construed as limiting the invention. Modifications and variations can be made to the above-described embodiments by those skilled in the art without departing from the spirit and scope of the present invention.
