[0003] Currently, general interfaces are directly plugged and unplugged. After the interfaces are connected to each other, the connection part is prone to looseness and detachment due to slight movement or collision of the surrounding environment, which will not only affect the signal transmission of the device and cause signal interruption, but also damage the interface and cause losses.
[0004] Therefore, it is necessary to design an interface with stable connection during use for the above problems. Summary of the Utility Model
[0005] The purpose of the utility model is to provide an interface with stable connection, which has the advantages of smooth insertion and extraction, fast and simple operation, ensures stable connection, and can be applicable to interfaces such as the gold finger interface of an image processor.
[0006] To solve the above problems, the utility model provides an interface with stable connection, which includes a housing, a pressing key, an elastic member and a functional component. The pressing key includes a pressing part, a rotating shaft, a buckle and an elastic member contact part. The function of the rotating shaft is to limit the moving direction and the moving angle size of the whole pressing part in the rotating shaft hole position of the housing. The pressing key and the elastic member are both installed in the housing. The elastic member contact part is in contact and cooperation with the elastic member. The buckle is used to achieve the locking effect of the interface. The length of the force arm formed between the pressing part and the rotating shaft is greater than the length of the force arm formed between the elastic member contact part and the rotating shaft, constituting a labor-saving lever. Applying pressure to the pressing part compresses the elastic member and makes the pressing key rotate around the rotating shaft, so that the buckle acts to achieve the unlocking effect.
[0007] According to an embodiment of the utility model, two groups of pressing keys are provided, which are respectively arranged at both sides of the housing, and can be optionally arranged at the left and right sides of the housing, or can also be arranged at the upper and lower sides.
[0008] According to an embodiment of the utility model, the elastic member contact part is located between the pressing part and the rotating shaft. While forming a labor-saving lever, the overall length of the pressing key is reduced.
[0009] Optionally, the functional component can be an interface component such as the gold finger interface of an image processor, USB, HDMI, etc.
[0010] In this solution, the functional component is a gold finger board, and a gold finger board positioning structure is provided on the housing.
[0011] According to an embodiment of the present utility model, the stably connected interface further includes a signal line, the signal line is connected to the functional component, and a signal line fixing groove and a cable fixing clip are provided in the housing.
[0012] According to an embodiment of the present utility model, the elastic member is a spring, and a spring limiting post is provided at the elastic member contact portion.
[0013] In this solution, the pressing key is preferably designed as a structure integrated with a rotating shaft, a spring limiting post, a pressing block and a buckle, which reduces the parts manufacturing process and lowers the production cost.
[0014] According to an embodiment of the present utility model, a spring limiting groove is provided in the housing, and the spring is installed in the spring limiting groove to fix the axial movement of the spring, prevent the radial position of the spring from shifting during the telescopic process, drive the pressing key to shift, and affect the buckling process and the smoothness of plugging and unplugging of the buckle.
[0015] According to an embodiment of the present utility model, the housing includes an upper housing and a lower housing, and the pressing key, the elastic member and the functional component are arranged between the upper housing and the lower housing.
[0016] Optionally, the upper housing and the lower housing can be connected by means of snap-fitting, adhesion, screws, etc.
[0017] According to an embodiment of the present utility model, a fusion guide line is provided between the upper housing and the lower housing, and the ultrasonic welding is used to complete the shaping and installation of the upper housing and the lower housing.
[0018] According to an embodiment of the present utility model, the rotation angle range of the pressing key around the rotating shaft is α, 0° < α < 10°. To avoid large-angle movement and position deviation, which will affect the smoothness of plugging and unplugging. This angle limit can be achieved through the structure of the rotating shaft hole position, or other structural limits can be set in the housing to achieve the angle limit.
[0019] The beneficial effect of the present utility model is that through the setting of the pressing key, in cooperation with the elastic member, the buckle forms a buckling connection with the protrusion inside the device interface or jack, completing the stable connection of the interface. Only by manually pressing the two pressing blocks simultaneously can the buckling connection be released and the interface be unplugged;
[0020] The distribution design of each component of the pressing key conforms to the lever principle, which can effectively reduce the force required to press the spring and facilitate the operation of personnel; the pressing key structure with the rotating shaft, the spring limiting post, the pressing part and the buckle integrally formed simplifies the number of parts and reduces the production cost; by restricting the rotation angle of the rotating shaft, the angle and position deviation of the pressing key can be effectively avoided.

Embodiment 1
[0032] An interface with stable connection, such as Figure 1 , includes a housing, a push button 4, an elastic member 7, and a functional component 1.
[0033] Among them, the functional component 1 can be an interface component such as an image processor gold finger interface, USB, HDMI, etc. In this embodiment, the gold finger interface is taken as an example.
[0034] Such as Figure 2 , the housing includes an upper shell 2 and a lower shell 3. The push button 4, the elastic member 7, and the functional component 1 are arranged in the space formed between the upper shell 2 and the lower shell 3. The upper shell 2 and the lower shell 3 can be connected by means of clamping, bonding, screws, etc. In this embodiment, ultrasonic welding is used for connection to make the appearance of the housing more beautiful. Specifically, such as Figure 3 , there are guide melting lines 21 at the connection parts of the upper shell 2 and the lower shell. The guide melting lines are installed in the guide melting grooves 36 of the lower shell, and finally the shaping installation of the housing is completed through ultrasonic welding.
[0035] A gold finger board positioning structure 31 is provided on the lower shell 3, generally using a positioning cylinder, and a matching positioning round hole is provided on the gold finger board. A screw hole 32 is also provided on the lower shell 3 for installing screws to fix the gold finger board. The signal line 5 is connected to the gold finger board. The signal line 5 passes through the limit board groove and the signal line fixing groove 35 in sequence, and finally extends out of the external through the signal line outlet provided on the shell. The signal line is locked in the signal line fixing groove 35 by the cable fixing clip 6 to enhance the structural stability.
[0036] Preferably, there are two groups of pressing keys 4, which are respectively arranged at the left and right positions of the shell, and can also be arranged at the upper and lower positions in other embodiments.
[0037] The pressing key 4 is integrally formed, achieving the effect of reducing the overall number of parts of the interface, reducing costs, and improving the assembly efficiency. In other embodiments, the functional parts on the pressing key 4 can also be separately arranged.
[0038] Such as Figure 4 , the pressing key 4 includes a pressing part 44, a rotating shaft 41, a buckle 43, and an elastic part contact part 42. The elastic part 7 is preferably a spring, and a spring limit cylinder is provided on the elastic part contact part 42.
[0039] A spring limit groove is provided in the lower shell 3, and the spring limit groove is formed between two spring limit plates 33. The spring is installed in the spring limit groove to limit the position of the spring. A rotating shaft hole position 34 is provided on the lower shell 3 for installing the rotating shaft 41. A hole position for the pressing part 44 and the buckle 43 to protrude is formed on the shell. The buckle 43 needs to be arranged in cooperation with the shape of the interface jack so that the buckle 43 can be clamped at the jack after the interface is inserted. Preferably, the shape of the buckle is as Figure 4 shown, and the front end face of the buckle has an inclined surface.
[0040] Such as Figure 7 shown, the elastic part contact part 42 is located between the pressing part 44 and the rotating shaft 41. The length of the force arm formed between the pressing part 44 and the rotating shaft 41 is greater than the length of the force arm formed between the elastic part contact part 42 and the rotating shaft 41, constituting a labor-saving lever, that is, the distance L1 between the pressing part 44 and the rotating shaft 41 is greater than the distance L2 from the limit cylinder to the rotating shaft. From F1×L1 = F2×L2, it can be known that when the pressing key moves around the rotating shaft, the force F1 required to be applied to the pressing part 44 will be less than the elastic force F2 generated by the spring compression. The user can easily apply force to compress the spring and insert the interface, improving the user experience.
[0041] Furthermore, as Figure 6 shown, the rotation angle range of the pressing key 4 around the rotating shaft 41 is α, 0° < α < 10°, to avoid large-angle movement and position deviation, which may affect the smoothness of plugging and unplugging. As Figure 3, this angular limit is achieved through the structure of the rotating shaft hole position 34, or other structural limits can be set in the housing to achieve the angular limit.
[0042] When assembling this interface, first install the spring 7 between two identical spring limit plates 33 in the lower housing 3. Then install the left pressing key 4 and the right pressing key into the lower housing respectively. The two ends of the spring are inserted into the spring limit cylinders on the pressing keys respectively. The two side rotating shafts 41 are placed in the rotating shaft hole positions 34 in the lower housing respectively. The buckles 43 and the pressing parts 44 are placed in the matching slot positions of the lower housing. Then weld the cable signal line 5 on the gold finger board. When installing, position the gold finger board through the two gold finger board positioning cylinders of the lower housing.
[0043] The operation process of inserting the interface is as follows: The user continuously presses the two side pressing parts simultaneously, so that the spring is compressed by the force of the spring limit cylinder, and the buckle also moves towards the inside of the housing around the rotating shaft, facilitating the insertion of the interface. After stopping the pressing, the spring immediately resets automatically, driving the left and right side buckles to also reset and move. During the movement, the buckle forms a clamping connection with the protrusion inside the device interface or jack, completing the stable connection of the interface. Only by manually pressing the two side pressing blocks simultaneously can the clamping connection be released and the interface be pulled out. This design can ensure that the buckle smoothly clamps the protrusion structure inside the device, and the operation process is fast, simple and labor-saving.
[0044] Those skilled in the art should understand that the above description and the embodiments of the present invention shown in the drawings are only examples and do not limit the present invention. The object of the present invention has been fully and effectively achieved. The function and structural principle of the present invention have been shown and described in the embodiments. Without departing from the said principle, any deformation and modification can be made to the embodiments of the present invention.
