Background

In a slidable electrical connection structure, as shown in fig. 1 and 2, a spring plate 02 is disposed on a lower surface of a first sliding member 01, an upper surface 031 of a second sliding member 03 is electrically conductive, and the spring plate 02 and the upper surface 031 of the second sliding member 03 are always in contact with each other and are electrically conductive in a relative sliding process of the first sliding member 01 and the second sliding member 03. Therefore, the first sliding member 01 and the second sliding member 03 keep circuit communication before and after sliding and are not influenced by relative movement.

However, in the structure shown in fig. 1, since sliding friction is always maintained between the resilient plate 02 and the upper surface 031 of the second sliding member 03 during the relative sliding of the first sliding member 01 and the second sliding member 03, the surface plating layer of the resilient plate 02 and the conductive plating layer of the upper surface 031 of the second sliding member 03 are easily worn, and the reliability of electrical connection is affected after long-term wear.

According to the terminal provided by the embodiment of the application, in the process of relative sliding of the first sliding part and the second sliding part, the conductive terminal is in contact with the second surface of the second sliding part and conducts electricity only when the conductive terminal is located at the initial position and the final position of the motion track, and the conductive terminal is separated from the second surface of the second sliding part in the process of sliding between the initial position and the final position, so that friction between the conductive terminal and the second surface of the second sliding part can be greatly reduced, the abrasion between the conductive terminal and the second surface of the second sliding part is reduced, and the reliability of electric connection is improved.

In a possible implementation, a groove may be provided on the second surface of the second slider, and when the conductive terminal is located between the starting position and the ending position, the conductive terminal corresponds to the groove and is separated from an inner wall of the groove. Therefore, the conductive terminal can be avoided through the groove in the relative sliding process of the first sliding part and the second sliding part, so that the conductive terminal is not in contact with the second surface of the second sliding part, and the abrasion of the conductive terminal and the second surface of the second sliding part is reduced.

In a possible implementation manner, the groove is located between the initial position and the final position of the conductive terminal, when the conductive terminal is located at the initial position and the final position of the motion track, the conductive terminal is located outside the groove, an end face of the conductive terminal, which is far away from the first sliding part, is in contact with the second surface, and when the conductive terminal is located between the initial position and the final position, the conductive terminal extends into the groove and is separated from the inner wall of the groove.

In a possible implementation manner, the conductive terminal is located in the groove, the groove includes a first sidewall and a second sidewall which are oppositely arranged, both the first sidewall and the second sidewall are conductive, and when the conductive terminal is located at the initial position, the first side surface of the conductive terminal is in contact with the first sidewall of the groove for conduction; when the conductive terminal is at the termination position, the second side surface of the conductive terminal is in contact with the second side wall of the groove for conducting electricity.

The spring thimble connector comprises a spring and a contact fixed at one end of the spring, when the conductive terminal is in contact with the second surface of the second sliding part for conduction, the spring is compressed, and the elastic force of the spring enables the contact to be in pressing contact with the second surface of the second sliding part; when the conductive terminal moves to the position of the groove, the spring resets, so that the contact extends into the groove but is not contacted with the inner wall of the groove.

In a possible implementation manner, the conductive terminal is a retractable member, the conductive terminal is connected to a driving device, and the driving device can drive the conductive terminal to extend out to be in contact with the second surface for conduction, or can drive the conductive terminal to retract to be separated from the second surface. Therefore, the groove is not formed, and the friction between the conductive terminal and the second surface is smaller.

Therefore, the electric connection between the conductive terminal and the second surface can be more reliable.

In a possible implementation manner, the conductive terminals include a first conductive terminal and a second conductive terminal, when the conductive terminals are located at the initial position, the first conductive terminal is in contact with the second surface for conducting electricity, and the second conductive terminal is separated from the second surface; when the conductive terminal is in the termination position, the first conductive terminal is separated from the second surface, and the second conductive terminal is in contact with the second surface for conduction.

Detailed Description

The embodiment of the application relates to a terminal which can be a mobile phone, a mobile computer, a handheld game machine, a tablet computer and the like.

The terminal has two parts capable of sliding relatively, for example, a keyboard and a screen of a mobile phone (a slide phone), a hidden camera and a main body of the mobile phone, and the two parts need to be electrically connected before and after sliding.

As shown in fig. 3, an embodiment of the present application provides a terminal, including a first sliding member 1 and a second sliding member 2, a first surface 11 of the first sliding member 1 is opposite to a second surface 21 of the second sliding member 2, a conductive terminal 3 is disposed on the first surface 11 of the first sliding member 1, the second surface 21 of the second sliding member 2 is conductive, when the first sliding member 1 and the second sliding member 2 slide relatively, a motion track of the conductive terminal 3 relative to the second surface 21 is a straight line, a sliding process is shown in fig. 3 to 5, and when the conductive terminal 3 is located at an initial position of the motion track, as shown in fig. 3, the conductive terminal 3 is in contact with the second surface 21 for conduction. When the conductive terminal 3 is in the end position of sliding, as shown in fig. 5, the conductive terminal 3 is in contact with the other side of the second surface 21 for conduction. When the conductive terminal 3 is between the starting position and the terminating position, as shown in fig. 4, the conductive terminal 3 is separated from the second surface 21.

In the terminal provided in the embodiment of the application, in the process of relative sliding between the first sliding member 1 and the second sliding member 2, because the conductive terminal 3 is only contacted and conducted with the second surface 21 of the second sliding member 2 when the conductive terminal 3 is at the initial position and the end position of the motion track, and when the conductive terminal 3 slides between the initial position and the end position (without the initial position and the end position), the conductive terminal 3 is separated from the second surface 21 of the second sliding member 2, friction between the conductive terminal 3 and the second surface 21 of the second sliding member 2 can be greatly reduced, so that the wear of the conductive terminal 3 and the second surface 21 of the second sliding member 2 is reduced, and the reliability of electrical connection is improved.

When the terminal is a mobile phone, the first sliding member 1 may be an upper sliding cover of the mobile phone, that is, a sliding cover including a display screen, and the second sliding member 2 may be a lower sliding cover of the mobile phone, that is, a sliding cover including a key portion. The arrangement can be reversed, that is, the first sliding part 1 can be a lower sliding cover for arranging keys on the mobile phone, and the second sliding part 2 can be an upper sliding cover for arranging a display screen on the mobile phone.

The electrically conductive second surface 21 of the second sliding member 2 may be entirely electrically conductive, or may be partially electrically conductive on the second surface 21, as long as the portion of the second surface 21 in contact with the electrically conductive terminal is electrically conductive.

In order to achieve that the conductive terminal 3 is separated from the second surface 21 of the second slider 2 during the sliding process, as shown in fig. 4, a groove 22 may be provided on the second surface 21 of the second slider 2, and when the conductive terminal 3 is located between the starting position and the ending position, the conductive terminal 3 corresponds to the position of the groove 22 and is separated from the inner wall of the groove 22. Therefore, the conductive terminal 3 can be avoided through the groove 22 in the relative sliding process of the first sliding part 1 and the second sliding part 2, so that the conductive terminal 3 is not in contact with the second surface 21 of the second sliding part 2, and the abrasion of the conductive terminal 3 and the second surface 21 of the second sliding part 2 is reduced.

One or two conductive terminals 3 may be provided. When there are two conductive terminals 3, as shown in fig. 6 to 8, the conductive terminals 3 include a first conductive terminal 3a and a second conductive terminal 3b, and the first conductive terminal 3a and the second conductive terminal 3b are arranged along the direction in which the first sliding member and the second sliding member slide relative to each other. In the initial position, as shown in fig. 6, the first conductive terminal 3a is in contact with the second surface 21 for conduction, and the second conductive terminal 3b is separated from the second surface 21; in the end position, as shown in fig. 8, the first conductive terminal 3a is separated from the second surface 21, and the second conductive terminal 3b is in contact with the second surface 21 for conduction. When the conductive terminal 3 is between the starting position and the end position, as shown in fig. 7, the first conductive terminal 3a is separated from the second surface 21, and the second conductive terminal 3b is also separated from the second surface 21. Therefore, the two conductive terminals 3 can be respectively used for realizing the electric connection before and after sliding, thereby prolonging the service life and improving the reliability of the whole electric connection structure.

In the above embodiment, after the groove 22 is disposed on the second surface 21 of the second sliding member 2, when the first conductive terminal 3a and the second conductive terminal 3b are at the initial position and the final position, they may be located in the groove 22, or may be located outside the groove 22. As shown in fig. 6, the groove 22 may be disposed between a start position of the first conductive terminal 3a and an end position of the second conductive terminal 3b, in the start position, an end surface of the first conductive terminal 3a away from the first sliding member 1 is in contact with the second surface 21 for conducting electricity, and the second conductive terminal 3b is separated from the second surface 21. As shown in fig. 8, in the terminal position, the first conductive terminal 3a is separated from the second surface 21, and the end surface of the second conductive terminal 3b away from the first sliding member 1 is in contact with the second surface 21 for conducting electricity. As shown in fig. 7, when the first conductive terminal 3a and the second conductive terminal 3b are between the initial position and the final position, the first conductive terminal 3a and the second conductive terminal 3b correspond to the position of the groove 22 and do not contact with the inner wall of the groove 22, so that the first conductive terminal 3a and the second conductive terminal 3b can be avoided from the second surface 21 of the second sliding member 2.

In another possible implementation manner, as shown in fig. 9, the first conductive terminal 3a and the second conductive terminal 3b may further extend into the groove 22, the groove 22 includes a first sidewall 221 and a second sidewall 222 that are oppositely disposed, both the first sidewall 221 and the second sidewall 222 are electrically conductive, in an initial position, as shown in fig. 9, a side surface of the first conductive terminal 3a is in contact with the first sidewall 221 of the groove 22 to be electrically conductive, and the second conductive terminal 3b is not in contact with the second sidewall 222 of the groove 22; in the sliding process, as shown in fig. 10, the side surface of the first conductive terminal 3a is separated from the first sidewall 221 of the groove 22, and the second conductive terminal 3b is gradually close to the second sidewall 222 of the groove 22; when sliding to the end position, as shown in fig. 11, the first conductive terminal 3a is separated from the first sidewall 221 of the groove 22, and the sidewall of the second conductive terminal 3b is in contact with the second sidewall 222 of the groove 22 for conduction. Therefore, the side wall of the groove 22 is contacted and pressed with the side surface of the conductive terminal 3 to realize the electric connection, so that the abrasion of the conductive terminal 3 can be further reduced.

The conductive terminal 3 may be an elastic member, and the conductive terminal 3 can be elastically deformed when contacting the second surface 21. Therefore, the conductive terminal 3 and the second sliding part 2 can form extrusion contact, so that the contact is tighter and the electric connection is more reliable.

There are various implementations of the elastic member, and in one possible implementation, as shown in fig. 12, the conductive terminal 3 may be an elastic sheet, where the elastic sheet includes a fixing portion 31 and an elastic contact portion 32, the fixing portion 31 is fixedly connected to the first sliding member 1, and the elastic contact portion 32 extends toward the second sliding member 2. Alternatively, the elastic contact portion 32 of the conductive terminal 3 may be perpendicular to the first surface 11 of the first sliding member 1, or may form an acute or obtuse angle with the first surface 11 of the first sliding member 1. In the case where the length of the elastic contact portion 32 is constant, when the elastic contact portion 32 forms an acute or obtuse angle with the first surface 11, the overall thickness of the terminal can be reduced.

Accordingly, in order to facilitate the pressing contact between the conductive terminal 3 and the sidewall of the groove 22, as shown in fig. 10, the sidewall of the groove 22 and the elastic contact portion 32 may be disposed substantially in parallel, that is, the first conductive terminal 3a and the first sidewall 221 of the groove 22 are substantially in parallel, and at this time, the first sidewall 221 of the groove 22 and the bottom surface of the groove 22 form an obtuse included angle; the second conductive terminal 3b is substantially parallel to the second sidewall 222 of the groove 22, and at this time, the second sidewall 222 of the groove 22 forms an obtuse included angle with the bottom surface of the groove 22. Thus, when the side wall of the groove 22 is brought into press contact with the elastic contact portion 32, deformation of the elastic contact portion 32 can be facilitated.

In order to make the side surface of the conductive terminal 3 contact with the side wall of the recess 22 well, as shown in fig. 10, a convex conductive contact 33 may be provided on the side surface of the conductive terminal 3. The conductive contact 33 is pressed against the side wall of the groove 22, so that the electrical contact can be made more compact and the reliability can be improved.

In another possible implementation manner, the conductive terminal 3 may also be a spring contact pin connector, the spring contact pin connector includes a spring and a contact fixed at one end of the spring, when the conductive terminal 3 is in contact with the second surface 21 of the second sliding member 2 for conducting electricity, the spring is compressed, and the elastic force of the spring makes the contact press-contact with the second surface 21 of the second sliding member 2; when the conductive terminal 3 moves to the position of the recess 22, the spring is reset, so that the contact extends into the recess 22 but does not contact with the inner wall of the recess 22.

In addition, the conductive terminal 3 can also be a telescopic piece, the conductive terminal 3 can be connected with a driving device, and the driving device can control the conductive terminal 3 to extend out or retract. When the conductive terminal 3 is at the initial position or the ending position, the driving device drives the conductive terminal 3 to extend out to contact with the second surface 21 of the second sliding part 2 for conduction, and when the conductive terminal 3 is between the initial position and the ending position, the driving device drives the conductive terminal 3 to retract, and the conductive terminal 3 is separated from the second surface 21 of the second sliding part 2. When the conductive terminal 3 adopts this structure, the second surface 21 of the second sliding member 2 may not be provided with the groove 22. Specifically, the driving device may be a linear driving mechanism, such as a linear motor, a rack and pinion assembly, and the like, which is not limited herein.

In another embodiment, the conductive terminal 3 may also be a magnetic-attraction type electrical connector, that is, the conductive terminal 3 has magnetism, and in the initial position or the terminal position, the conductive terminal 3 can magnetically attract with the second surface 21 of the second sliding member 2 to form an electrical connection. In the process of relative sliding of the first sliding part 1 and the second sliding part 2, the conductive terminal 3 and the second surface 21 of the second sliding part 2 repel magnetically, so that contact is avoided and friction is reduced.

The above description is only for the specific embodiments of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art can easily conceive of the changes or substitutions within the technical scope of the present invention, and all the changes or substitutions should be covered within the scope of the present invention.
