Technical Field

The application relates to the technical field of terminals, in particular to a positioning structure and a terminal.

Background

The terminal is generally provided with an interface connector for transmitting current or signals, and the interface connector is connected with external equipment, so that corresponding functions can be realized. With the rapid development of the technology and the more diversified service environments of the terminal, the user has higher and higher requirements on the dustproof and waterproof performance of the terminal.

Generally, in order to improve the dust-proof and waterproof performance of the terminal, a waterproof rubber ring is usually wrapped around the plug-in end of the interface connector. However, when the interface connector with the waterproof rubber ring is assembled on the middle frame of the terminal, the interface connector is often inclined due to improper assembly, which results in that the plugging side of the interface connector and the inner wall of the middle frame cannot be sealed, and thus the waterproof and dustproof performance of the terminal is low.

Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some, but not all, of the embodiments of the present application. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

Unless defined otherwise, all technical terms used in the examples of the present application have the same meaning as commonly understood by one of ordinary skill in the art.

In order to make the technical solutions and advantages of the present application clearer, the following will describe the embodiments of the present application in further detail with reference to the accompanying drawings.

As shown in fig. 1, the embodiment of the present application provides a positioning structure, which has a body 100 and a positioning member 200. The body 100 is provided with a groove 110 and an opening 120, and the opening 120 communicates with the groove 110. The positioning member 200 is mounted in the recess 110, and the positioning member 200 has an ability to be elastically deformed in a direction toward the opening 120. Wherein the portion of the recess 110 between the positioning member 200 and the opening 120 is adapted to receive the socket 310 of the interface connector 300, and the opening 120 is adapted to receive the mating portion of the interface connector 300. It should be noted that the positioning member 200 has the capability of being elastically deformed in the direction toward the opening 120, which means that the positioning member 200 can be elastically deformed to be away from the opening 120 or close to the opening 120. That is, when the positioning member 200 is pressed in a direction from the opening 120 to the seat body 310 of the interface connector 300, the positioning member 200 is elastically deformed and moves to a side away from the opening 120. When the pressing force is removed or reduced, the positioning member 200 is restored from the elastic deformation so as to be movable toward a side close to the opening 120.

By adopting the positioning structure provided by the embodiment of the present application, when the interface connector 300 and the positioning structure are assembled together, because the positioning member 200 has the elastic deformation capability, after the positioning member 200 is pressed by the seat body 310 of the interface connector 300, the positioning member can be away from the opening 120 to enable the seat body 310 of the interface connector 300 to enter the groove 110 more easily, so as to ensure that the interface connector 300 can be assembled in place, that is, to facilitate assembling or disassembling the interface connector 300. After the seat body 310 of the interface connector 300 is assembled in place, because the positioning member 200 has elastic deformation capability, the positioning member 200 can move towards the direction close to the opening 120 and provide a pressing force towards one side of the opening 120 to the seat body 310 of the interface connector 300, thereby ensuring that the plugging side of the interface connector 300 is abutted against the sidewall 111 around the opening 120 of the groove 110 to form a seal, and improving the waterproof and dustproof performance.

Generally, if interface connector 300 is a device on a terminal, the positioning structure may be formed by a bezel in the terminal and its accessory components. In order to improve the sealing performance of the plugging side of the interface connector 300, the periphery of the plugging side of the housing 310 of the interface connector 300 is generally wrapped with a waterproof rubber ring 700. By adopting the above positioning structure, under the elastic force of the positioning member 200, the waterproof rubber ring 700 is ensured to be always abutted against the side wall 111 around the opening 120 of the groove 110 to form a seal, so that the waterproof and dustproof performance of the plugging side of the interface connector 300 can be improved.

The details and functions of the positioning structure provided by the embodiments of the present application will be described in more detail with reference to fig. 1 to 3.

In some embodiments, the positioning element 200 is made of plastic, so that the positioning element 200 has a better elastic deformation capability.

As shown in fig. 1, in some embodiments, the positioning member 200 extends along the width direction of the interface connector 300, and there is a space between the middle portion of the positioning member 200 and the sidewall 111 of the recess 110 away from the opening 120. It will be appreciated that by installing the positioning member 200 in this orientation, it is ensured that the middle portion of the positioning member 200 and the end surface of the housing 310 of the interface connector 300 away from the opening 120 can contact each other when the interface connector 300 is assembled in the recess 110 between the positioning member 200 and the opening 120. Thus, after the interface connector 300 is assembled, the positioning member 200 can provide a pressing force to the interface connector 300 from the seat 310 to the opening 120, so that the plugging side of the interface connector 300 can always abut against the sidewall 111 around the opening 120 of the recess 110 to form a seal. Meanwhile, in the process of placing the seat body 310 of the interface connector 300 into the groove 110, the seat body 310 of the interface connector 300 applies a pressing force to the positioning element 200 in a direction from the opening 120 to the seat body 310, and the positioning element 200 is elastically deformed and moves toward the side wall 111 of the groove 110 away from the opening 120 under the pressing force. Since the space is formed between the middle portion of the positioning member 200 and the sidewall 111, a moving space can be provided for the movement of the positioning member 200, which facilitates the movement of the positioning member 200.

As shown in fig. 2, in some embodiments, the positioning member 200 is provided with a convex hull 210, and the convex hull 210 protrudes towards the opening 120. It should be noted that, after the seat body 310 of the interface connector 300 is assembled into the groove 110, the positioning element 200 may rebound, and the protrusion 210 may ensure that the positioning element 200 is always in contact with the seat body 310 of the interface connector 300, so that the positioning element 200 may provide a pressing force to the seat body 310 of the interface connector 300 from the seat body 310 to the opening 120, thereby improving the reliability of positioning the interface connector 300. Thereby ensuring that the plugging side of the housing 310 can always abut against the peripheral side wall 111 of the opening 120 of the groove 110 to form a seal. Through this setting, the gas tightness between the grafting side of the pedestal 310 of the interface connector 300 and the location structure is improved, that is, the waterproof and dustproof performance of the grafting side of the interface connector 300 is improved.

In some embodiments, the convex hull 210 comprises a hollow cylindrical arc wall or a hollow sphere arc wall. It should be noted that the hollow cylindrical arc wall is a part of the arc wall of the hollow cylinder, and the hollow sphere arc wall generally refers to a part of the arc wall of the hollow sphere.

As shown in fig. 2, in some embodiments, the positioning member 200 includes a first sub-positioning member 220, a second sub-positioning member 230 and a third sub-positioning member 240, wherein the first sub-positioning member 220, the second sub-positioning member 230 and the third sub-positioning member 240 are sequentially arranged in an extending direction of the positioning member 200. The first sub-positioning element 220 is arc-shaped, and a portion of the first sub-positioning element 220 abuts against the sidewall 111 of the groove 110 away from the opening 120. The second sub-positioning member 230 is linear, and a space is formed between the second sub-positioning member 230 and the sidewall 111 of the recess 110 far away from the opening 120. The third sub-positioning element 240 is arc-shaped, and a portion of the third sub-positioning element 240 abuts against the sidewall 111 of the groove 110 far away from the opening 120. It can be understood that, since the first sub-positioning element 220 and the third sub-positioning element 240 are both arc-shaped and abut against the side wall 111 of the groove 110, the side wall 111 of the groove 110 far from the opening 120 can position and support the positioning element 200.

In some embodiments, the shape of the first sub-positioning member 220 and the shape of the third sub-positioning member 240 are matched with the shape of the sidewall 111 of the recess 110 far from the opening 120. As shown in fig. 2, the side wall 111 of the groove 110 away from the opening 120 is curved, so that the curvature of the portion of the first sub-positioning element 220, which abuts against the side wall 111, matches the curvature of the side wall 111, and the curvature of the portion of the third sub-positioning element 240, which abuts against the side wall 111, also matches the curvature of the side wall 111. Therefore, the portion of the first sub-positioning element 220 abutting against the sidewall 111 and the portion of the third sub-positioning element 240 abutting against the sidewall 111 are both in contact with the sidewall 111 more closely, so that the groove 110 can perform better positioning and supporting functions on the positioning element 200.

As shown in fig. 2, in some embodiments, the convex hull 210 is disposed on the second sub-positioning member 230. It will be appreciated that when the interface connector 300 is assembled, the end surface of the body 310 of the interface connector 300 remote from the opening 120 abuts against the second sub-positioning member 230, and the second sub-positioning member 230 provides a force to the body 310 of the interface connector 300 in a direction from the body 310 toward the opening 120. Since the second sub-positioning member 230 is the middle portion of the positioning member 200, the arrangement of the convex hull 210 on the second sub-positioning member 230 can ensure the balance of the forces on the two sides of the seat body 310 of the interface connector 300, thereby avoiding the phenomenon of the improper assembly caused by the inclination of the seat body 310 of the interface connector 300. Further, the plugging side of the interface connector 300 is always abutted against the peripheral side wall 111 of the opening 120 of the groove 110, thereby improving the overall waterproof and dustproof performance. In some embodiments, the convex hull 210 is located at the midpoint of the second sub-positioning member 230, so as to further ensure the force balance between the two sides of the seat body 310 of the interface connector 300.

In some embodiments, the positioning member 200 and the body 100 are integrally formed, or the positioning member 200 and the body 100 are independent from each other. Under the condition that be integrated into one piece between setting element 200 and the body 100, the both ends and the body 100 integrated into one piece of setting element 200 to realize fixed connection, the both ends of setting element 200 can also play the effect of support for setting element 200. And the middle portion of the securing member 200 is movably installed in the recess 110 so that the middle portion of the securing member 200 can be moved by a force. For example, the portion of the first sub-positioning member 220 away from the second sub-positioning member 230 is integrally formed with the body 100, and the other portion of the first sub-positioning member 220 is movably mounted in the groove 110. The portion of the third sub-positioning member 240 away from the second sub-positioning member is integrally formed with the body 100, and the other portion of the third sub-positioning member 240 is movably mounted in the groove 110. Also, the first sub-positioning member 220 is movably installed in the recess 110. Therefore, when the interface connector 300 is installed, the portion of the first sub-positioning member 220 movably installed in the groove 110, the portion of the third sub-positioning member 240 movably installed in the groove 110, and the second sub-positioning member 230 are elastically deformed by a force, and can move toward the side away from the opening 120, so as to provide an installation space for the interface connector 300, thereby facilitating the assembly process and improving the assembly efficiency. When the interface connector 300 is assembled into position, the positioning member 200 is restored from elastic deformation so as to be movable toward a side near the opening 120. Under the condition that the positioning element 200 and the body 100 are independent from each other, stepped surfaces may be disposed at positions of the groove 110 corresponding to two ends of the positioning element 200, and the two ends of the positioning element 200 may abut against the stepped surfaces, so as to position the positioning element 200.

In some embodiments, a gap 250 is formed between the second sub-positioning member 230 and the third sub-positioning member 240, or a gap is formed between the second sub-positioning member 230 and the first sub-positioning member 220. It should be noted that, when a gap 250 is formed between the second sub-positioning element 230 and the third sub-positioning element 240, the first sub-positioning element 220 and the second sub-positioning element 230 are in a connected state. When there is a gap between the second sub-positioning element 230 and the first sub-positioning element 220, the second sub-positioning element 230 and the third sub-positioning element 240 are connected. Fig. 3 shows a situation where a gap 250 exists between the second sub-positioning element 230 and the third sub-positioning element 240. The following description will be given by taking the case shown in fig. 3 as an example: since the gap 250 is provided, the second sub-positioner 230 and the third sub-positioner 240 are not in contact with each other until the interface connector 300 is assembled into the recess 110, and thus, the degree of freedom of movement of the second sub-positioner 230 under a force can be increased. During assembly of the port connector 300, the second sub-positioning member 230 is elastically deformed by the pressing force of the seat 310 of the port connector 300 and then moved away from the opening 120, thereby facilitating the assembly of the port connector 300. When the interface connector 300 is assembled into position, the second sub-positioning member 230 is restored from elastic deformation so as to be movable toward a side close to the opening 120. Meanwhile, when the interface connector 300 needs to be detached or replaced, since the second sub-positioning member 230 can be forced to elastically deform and then move towards the side away from the opening, the detachment or replacement operation can be performed more easily and more laborsavingly, and damage to the interface connector 300 or other surrounding structures due to excessive resistance in the detachment or replacement process is avoided. It should be noted that the same principle is applied to the case where the gap is formed between the second sub-positioning element 230 and the first sub-positioning element 220, and the description thereof is omitted here.

As shown in fig. 2, in some embodiments, the positioning member 200 is provided with a chamfer 260 away from the bottom of the groove 110 and toward the edge of the opening 120. It will be appreciated that when assembling the interface connector 300, the interface connector 300 may be brought into the recess 110 in the direction of the chamfer 260 to complete the assembly. That is, the chamfer 260 has a better guiding function, so as to facilitate the positioning of the interface connector 300 and facilitate the assembling process of the interface connector 300. In some embodiments, the chamfer 260 is disposed at an edge of the first sub-positioning member 220 away from the groove bottom of the groove 110 and toward the opening 120 and an edge of the second sub-positioning member 230 away from the groove bottom of the groove 110 and toward the opening 120. The angle of the chamfer 260 may be set as desired, for example, 30 degrees, 45 degrees, 60 degrees, etc.

As shown in fig. 2, in some embodiments, the height of the positioning member 200 is not greater than the depth of the recess 110. It should be noted that the depth of the groove 110 herein refers to the depth of the position of the groove 110 corresponding to the installation position of the positioning member 200. The positioning member 200 does not go beyond the upper edge of the recess 110 by this arrangement. When other structures around the positioning member 200 are assembled, the interference between the other structures and the positioning member 200, which results in damage to the positioning member 200, can be avoided, that is, the positioning member 200 can be better protected.

The positioning structure provided by the embodiment of the present application can more conveniently assemble the interface connector 300 into the body 100 and can ensure that the interface connector 300 is assembled in place. Meanwhile, the plugging side of the interface connector 300 can be always abutted against the side wall 111 around the opening 120 of the groove 110 to form a seal, and the waterproof and dustproof performance of the plugging side of the interface connector 300 is improved.

As shown in fig. 1 to 5, the present application further provides a terminal, which includes an interface connector 300 and a positioning structure as described in any one of the above, where the interface connector 300 is positioned in the positioning structure. It should be noted that the interface connector 300 may be a Type-C interface connector. The composition and function of each part of the positioning structure are the same as those of the positioning structure in the embodiment of the present application, and are not described herein again. Generally, if interface connector 300 is a device on a terminal, the positioning structure may be formed by a bezel in the terminal and its accessory components. In order to improve the sealing performance of the plugging side of the interface connector 300, the periphery of the plugging side of the housing 310 of the interface connector 300 is generally wrapped with a waterproof rubber ring 700.

As shown in fig. 4, in some embodiments, the terminal further includes a PCB (Printed Circuit Board) 400, and a side of the interface connector 300 away from the opening 120 is provided with a clip portion 320, wherein the clip portion 320 is used for being clipped into a corresponding mounting hole on the PCB 400, so as to fix the PCB 400 and the interface connector 300 together. It should be noted that fig. 4 is only a partial schematic structural diagram of the PCB 400, and the shape of the PCB 400 can be set as required. The number of the catching portions 320 may be one, two, or more. The mounting holes of the PCB 400 correspond to the clamping portions 320 one to one.

As shown in fig. 4, in some embodiments, the soldering portion of the interface connector 300 is fixed to an FPC (Flexible Printed Circuit) 500, wherein the FPC500 is located on one side of the PCB 400 near the groove 110. Fig. 4 is a schematic view of a part of the structure of the FPC500, and the shape of the FPC500 may be set as required.

As shown in fig. 5, in some embodiments, the terminal further comprises a press cover plate 600, the press cover plate 600 is located at a side of the PCB board 400 facing away from the recess 110, the press cover plate 600 is used to cover the PCB board 400, so that the interface connector 300 can be further fixed to position the interface connector 300 more stably. Fig. 5 is a schematic view of only a part of the structure of the pressing cover plate 600, and the shape of the pressing cover plate 600 may be set as required.

In the embodiment of the present application, the terminal includes the positioning structure in the above embodiments, when the interface connector 300 is assembled with the positioning structure, because the positioning member 200 in the positioning structure has an elastic deformation capability, the interface connector 300 can be assembled into the groove 110 disposed on the body 100 of the positioning structure more easily, so as to ensure that the interface connector 300 is assembled in place, that is, the interface connector 300 is more convenient to assemble or disassemble, and the assembly efficiency of the whole machine is improved. After the seat body 310 of the interface connector 300 is assembled in place, since the positioning member 200 has elastic deformation capability, the positioning member 200 can move towards the direction approaching to the opening 120 and provide a pressing force towards one side of the opening 120 to the seat body 310 of the interface connector 300, so as to ensure that the plugging side of the interface connector 300 is always abutted against the sidewall 111 around the opening 120 of the groove 110 to form a seal. Thereby improving the sealing performance between the interface connector 300 and the positioning interface and also improving the waterproof and dustproof performance of the terminal. Meanwhile, because the positioning member 200 has elasticity and can move in the groove 110 toward the opening 120 far away from or close to the groove 110, when assembling the interface connector 300, the phenomenon that the seat body 310 and other parts of the interface connector 300 are damaged due to overlarge extrusion force between the positioning member 200 and the seat body 310 can be avoided, the interface connector 300 can be better protected, and the maintenance cost generated in the assembling process of the interface connector 300 is reduced. In addition, because the positioning member 200 has elasticity, if the interface connector 300 needs to be replaced or disassembled, the seat body 310 of the interface connector 300 can be easily taken out of the groove 110, and at this time, the FPC500 connected with the interface connector 300 can be prevented from being damaged or failing due to large resistance or pulling force in the disassembling process, thereby reducing the maintenance cost in the replacing and disassembling process.

Other embodiments of the present application will be apparent to those skilled in the art from consideration of the specification and practice of the present application disclosed herein. This application is intended to cover any variations, uses, or adaptations of the invention following, in general, the principles of the application and including such departures from the present disclosure as come within known or customary practice within the art to which the invention pertains.
