Detailed Description
The present application will be described in detail hereinafter with reference to the accompanying drawings in conjunction with embodiments. It should be noted that, in the case of no conflict, the embodiments and features in the embodiments may be combined with each other.
It should be noted that the terms "first," "second," and the like in the description and claims of the present application and the above figures are used for distinguishing between similar objects and not necessarily for describing a particular sequential or chronological order.
In a first aspect, referring to fig. 1 to 4, an embodiment of the present application provides a terminal structure, including: a holder 100 and two elastic members 200.
Two elastic members 200 disposed opposite to each other on the holder 100; the elastic member 200 includes a support arm 210, a first elastic arm 220, and a movable portion 230 connected in sequence, the support arm 210 extends in a direction away from the holder 100, the movable portion 230 extends in a direction close to the holder 100, the movable portion 230 has a first contact 201 and a second contact 202 arranged oppositely, the first contact 201 faces the circuit board 30 or the conductive site of the chip 40, and the second contact 202 is arranged towards the support arm 210;
the elastic member 200 has a first state in which the first contact 201 abuts against the conductive site of the circuit board 30 or the chip 40 and a second state in which the second contact 202 abuts against the support arm 210; in the second state, the second contact 202 is away from the support arm 210.
In this embodiment, by optimizing the specific structure of the terminal structure 10, the elastic working range of the terminal structure 10 is improved while the terminal structure 10 can transmit high-speed signals, so that the plasticity of the terminal structure 10 after multiple compression is reduced, the practicability and reliability of the terminal structure 10 are effectively improved, and the connection between the chip 40 and the circuit board 30 is more reliable and efficient.
Specifically, the terminal structure 10 is configured as a combined member including at least a holder 100 and two elastic members 200, wherein the holder 100 is used for being connected with an insulating member, and the two elastic members 200 are respectively used for being electrically connected with conductive sites of the circuit board 30 and the chip 40, so as to realize conduction and signal transmission of the terminal structure 10 to the circuit board 30 and the chip 40. And, through further structural optimization, dispose the elastic member 200 into the V style of calligraphy structure of horizontal putting, the elastic member 200 of this V style of calligraphy structure transversely arranges between circuit board 30 and chip 40, so, is favorable to reducing the space that terminal structure 10 occupies, realizes miniaturization, the exquisite arrangement of terminal structure 10.
Specifically, the elastic member 200 is configured as a combined member including at least a support arm 210, a first elastic arm 220 and a movable portion 230, wherein the support arm 210 is configured to provide a supporting force to the first elastic arm 220 and the movable portion 230, the first elastic arm 220 is configured to provide an elastic force to the movable portion 230, and the movable portion 230 is configured to electrically connect to the circuit board 30 or the chip 40. The movable portion 230 can move in a direction approaching or separating from the supporting arm 210, and the movement track is the elastic working range of the terminal structure 10 between the circuit board 30 and the chip 40. It can be appreciated that the first elastic arm 220 provides at least a two-layer elastic working range for the movable portion 230, and one of the two-layer elastic working range is that the first elastic arm 220 provides an elastic force for the movable portion 230 from abutting against the supporting arm 210 to being far away from the supporting arm 210 when the movable portion 230 is moved from the second state to the first state; secondly, after the movable portion 230 is in the first state, when the circuit board 30 and the chip 40 continue to compress the terminal structure 10, the movable portion 230 deforms itself, and the first elastic arm 220 also provides an elastic force for the movable portion 230 to recover from the deformed state to the original state. In this way, the deformation space and the elastic working range of the elastic member 200 are greatly improved by the at least two layers of elastic force provided by the first elastic arm 220.
Meanwhile, the movable portion 230 of the elastic member 200 is configured to abut against the second contact 202 of the supporting arm 210, so that when the terminal structure 10 is in a working state, a dual-loop path can be formed on the elastic member 200 of the terminal structure 10 to realize conduction of an electrical signal, thereby avoiding occurrence of transmission of high-speed signals due to only one signal path in the conventional terminal structure 10, which is longer in path and unfavorable for the transmission of high-speed signals, and the stability and reliability of the terminal structure 10 on the high-speed signal transmission are effectively improved due to arrangement of multiple-loop paths.
Based on this, the working principle of the terminal structure 10 is further elucidated as follows:

Two spring elements 200 are disposed between the circuit board 30 and the chip 40, wherein one spring element 200 is configured to electrically connect to a conductive site of the circuit board 30 and the other spring element 200 is configured to electrically connect to a conductive site of the chip 40, such as, but not limited to, the two spring elements 200 being disposed one above the other.
In the second state, the two elastic members 200 are in a free state. In the first state, the two elastic members 200 are in a compression stress state, specifically, the first contacts 201 of the two elastic members 200 are respectively abutted to the conductive sites of the circuit board 30 and the chip 40, and the second contacts 202 are respectively abutted to the corresponding supporting arms 210, so that dual-loop paths are respectively formed on the two elastic members 200 of the terminal structure 10, and high-speed signal transmission between the circuit board 30 and the chip 40 is realized. When the elastic member 200 is in the first state, the distance between the circuit board 30 and the chip 40 is continuously compressed, at this time, the shape of the movable portion 230 is deformed, and the movable portion 230 continuously moves toward the direction approaching to the holder 100, and the ends of the two support arms 210 far away from the holder 100 are gradually separated, so as to provide a smaller elastic deformation amount for the whole of the first elastic arm 220 and the movable portion 230 through the support arms 210, thereby further increasing the elastic working range of the terminal structure 10 through the support arms 210.
Of course, the two elastic members 200 may be used to connect between conductive sites of the two chips 40 to achieve a communication connection between the two chips 40. And, in other embodiments, two spring members 200 may also be used to connect between conductive sites of two circuit boards 30 to enable a communicative connection between the two circuit boards 30.
In one possible embodiment, the first elastic arm 220 is bent, the first end of the first elastic arm 220 is connected to the supporting arm 210, the second end of the first elastic arm 220 is connected to the movable portion 230, and in the first state, a first angle between a tangent line of the first end and a tangent line of the second end is 30 ° to 90 °.
In this embodiment, the specific structure of the first elastic arm 220 is set. Specifically, the first elastic arms 220 are arranged in a curved manner, and the degree of bending of the first elastic arms 220 is set so that the included angle between tangents at opposite ends of the first elastic arms 220 is maintained between 30 ° and 90 °. For example, but not limited to, the included angle between the tangents at the opposite ends of the first elastic arm 220 is configured to be 45 °, and the bending degree of the first elastic arm 220 is larger, so that a larger deformation elastic force can be provided to the movable portion 230.
Alternatively, the first elastic arm 220 has a cross-sectional shape of a segment of an arc of a circle in the moving direction of the movable portion 230.
In one possible embodiment, the movable portion 230 includes a first cantilever 231, a second elastic arm 232, and a second cantilever 233 connected in sequence, one end of the first cantilever 231 away from the second elastic arm 232 is connected to the first elastic arm 220, the first cantilever 231 extends in a direction approaching the holder 100, and the second cantilever 233 extends in a direction approaching the support arm 210;
the first contact 201 is disposed on the second elastic arm 232, and the second contact 202 is disposed on an end of the second cantilever 233 near the support arm 210.
In this embodiment, the specific structure of the movable portion 230 is optimized. Specifically, the movable portion 230 is configured as a combined member including at least a first cantilever 231, a second elastic arm 232 and a second cantilever 233, and the combined member forms a transverse V-shaped structure. The second elastic arm 232 is used to provide an elastic force for restoring the second cantilever 233 to its original position, and is also used to electrically connect the conductive sites of the circuit board 30 or the chip 40.
Thus, by providing the specific structure of the movable portion 230, the elastic member 200 is configured as a combined member including at least two V-shaped structures, and the two V-shaped structures are disposed back to form an ear-shaped structure. Further, the terminal structure 10 is configured as a combined member of at least a binaural structure, by which the elastic deformation amount of the terminal structure 10 is greatly increased in the moving direction of the movable portion 230, and the elastic operation range of the terminal structure 10 is increased.
In one possible embodiment, the second elastic arm 232 is bent, the third end of the second elastic arm 232 is connected to the first cantilever 231, the fourth end of the second elastic arm 232 is connected to the second cantilever 233, and in the first state, the second angle between the tangent line of the third end and the tangent line of the fourth end is 15 ° to 75 °.
In this embodiment, the specific structure of the second elastic arm 232 is set. Specifically, the second elastic arms 232 are arranged in a curved manner, and the degree of bending of the second elastic arms 232 is optimized, so that the included angle between tangents at two opposite ends of the second elastic arms 232 is kept between 15 ° and 75 °. For example, but not limited to, the included angle between the tangents at the opposite ends of the second elastic arm 232 is configured to be 15 °, at which time the second elastic arm 232 is bent more gently, so as to provide a proper deformation elastic force to the second cantilever 233.
Alternatively, the second elastic arm 232 has a sectional shape of a segment of an arc of a circle in the moving direction of the movable portion 230.
In one possible embodiment, the degree of bending of the first and second resilient arms 220, 232 is optimized. Specifically, the second included angle is smaller than the first included angle. For example, but not limited to, a plate having a radius of the circle in which the first elastic arm 220 is located is greater than a radius of the circle in which the second elastic arm 232 is located.
In one possible embodiment, the movable portion 230 further includes an abutment 234, and the abutment 234 is connected to an end of the second cantilever 233 remote from the second elastic arm 232;
the second contact 202 is provided to the abutment 234.
In this embodiment, the specific structure of the movable portion 230 is set. Specifically, the movable portion 230 is configured as a combined member including at least the first cantilever 231, the second elastic arm 232, the second cantilever 233, and the abutment 234. The abutting piece 234 is used for abutting the supporting arm 210, so as to avoid that the end of the second cantilever 233 directly abuts against the supporting arm 210, and certain irreversible mechanical damages such as crashes, scratches and the like are caused to the supporting arm 210, thereby prolonging the service life of the whole terminal structure 10.
In one possible embodiment, the cross section of the abutment 234 in the movement direction of the movable portion 230 is any one of a circle, an arc, a wave, a semicircle, a line, a triangle, a rectangle, a diamond, a pentagon, or a hexagon.
In the present embodiment, the abutting piece 234 is structured. Specifically, the abutment 234 may be configured in a spherical structure. Of course, in other embodiments, the abutment 234 may be configured as an arcuate plate-like structure, a hemispherical structure, a wavy plate-like structure, an elliptical structure, a triangular pyramid structure, a prismatic structure, a polyhedral structure, or the like. Preferably, to save raw materials, the abutting piece 234 is configured as an arc-shaped plate-like structure, and the arc surface of the abutting piece 234 abuts on the support arm 210.
Referring to fig. 5 and 6, in one possible embodiment, the first included angles of the two elastic members 200 are different.
In the present embodiment, the specific structures of the two elastic members 200 are configured. Specifically, the two elastic members 200 are configured in an asymmetric structure, so that one elastic member 200 can provide a larger elastic force, and the other elastic member 200 can provide a moderate elastic force, so as to meet the personalized requirement.

In this embodiment, the arrangement positions of the two elastic members 200 are optimized. Specifically, the two elastic members 200 are arranged at a distance so that the two support arms 210 are in a non-contact state when in a non-operating state. At this time, the support arm 210 provides a certain elastic force to the first elastic arm 220 and the movable portion 230, and the elastic working range of the terminal structure 10 is increased by the moving distance of the support arm 210 in the moving direction of the movable portion 230.
Referring to fig. 7-10, in one possible embodiment, the terminal structure 10 further includes a fastener 300, the fastener 300 being used to lock the support arms 210 of the two spring members 200.

In one possible embodiment, the supporting arms 210 are obliquely disposed on the holder 100, and the supporting arms 210 of the two elastic members 200 are gradually folded in the extending direction of the supporting arms 210.

In one aspect, the two support arms 210 in an inclined arrangement may provide a range of resilient operation for the movable portion 230 when no other structural members are disposed between the two support arms 210.
On the other hand, when the fastening member 300 is disposed between the two support arms 210, the fastening member 300 can fold the two support arms 210 disposed obliquely to form a triangle area, so that the structure formed by enclosing the two support arms 210 and the holder 100 is more stable and less affected by external force.

In the present embodiment, the specific structure of the holder 100 is optimized. Specifically, the holder 100 is configured as a combined member including at least a body 110, a first connecting arm 120 and a second connecting arm 130, wherein the first connecting arm 120 and the second connecting arm 130 are respectively connected to opposite sides of the body 110 to form the holder 100 with an H-shaped structure.
