Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.
In mobile devices such as mobile phones and wearable devices, board-to-board connectors are generally used to realize board-to-board connection of circuit boards. However, the holding force between the connectors is insufficient, which easily causes the problems of poor contact, loosening and the like, and affects the service performance and the service life of the product. The extra pressing structure for the connector also occupies the internal space of the portable device, which is not favorable for the lightness and thinness of the device.
The present disclosure provides a connector and a circuit board assembly to improve the connection stability of the connector and reduce the space occupation caused by the stable connection of the connector. The connector and circuit board assembly of the present disclosure will be described in detail with reference to the accompanying drawings. The features in the following examples and embodiments may be combined with each other without conflict.
Referring to fig. 1 to 11, an embodiment of the present disclosure provides a connector 100 including a first chassis 10 and a second chassis 20. The first base 10 includes a first base body 11, a first locking portion 12 and an unlocking portion 13, the first locking portion 12 is disposed on the first base body 11, the unlocking portion 13 is movably disposed on the first base body 11 along a first direction X, and the first locking portion 12 and the unlocking portion 13 are disposed along a second direction Y perpendicular to the first direction X at intervals. The second base 20 includes a second base body 21 for mating with the first base body 11 along the second direction Y and a second locking portion 22 for locking and mating with the first locking portion 12, and the second locking portion 22 is disposed on the second base body 21. Wherein the second direction Y is perpendicular to the first direction X.
As shown in fig. 2 to 4, after the first base 10 and the second base 20 are inserted, the first locking portion 12 and the second locking portion 22 are locked with each other, and the unlocking portion 13 abuts against the second locking portion 22. When the first base 10 and the second base 20 need to be removed, and the unlocking portion 13 moves along the first direction X, the second locking portion 22 is driven to move in a direction away from the first locking portion 12, so that the first locking portion 12 is separated from the second locking portion 22, and the first base 10 is removed from the second base 20. Alternatively, the first locking portion 12 is provided to an outer wall of the first base body 11. The second base body 21 is provided in a housing cavity 23 for housing the first base body 11, and the second locking portion 22 is provided on an inner side wall of the housing cavity 23.
Thus, when the first base 10 and the second base 20 need to be plugged, the connector 100 of the present disclosure can fix the first base 10 and the second base 20 to each other through the locking and locking cooperation of the first locking portion 12 and the second locking portion 22, that is, the first base 10 and the second base 20 of the connector 100 can be automatically locked after being buckled, thereby preventing the electrical connection failure inside the device caused by the separation of the first base 10 and the second base 20 when the electronic device falls off, and the like, improving the plugging stability of the first base 10 and the second base 20, and not needing to set an additional connection and fixation structure for the connector 100, and reducing the space occupation caused by additionally setting the connection and fixation structure for improving the stability of the connector 100. When the first base 10 needs to be detached from the second base 20, the unlocking portion 13 is moved along the first direction X, and the second locking portion 22 can be driven to move away from the first locking portion 12, so that the first locking portion 12 is separated from the second locking portion 22.
It is understood that the first base 10 can be understood as a male socket and the second base 20 can be understood as a female socket, the male socket mating with the female socket. The male connector and the female connector may include a metal terminal having functions of conducting current and holding connection, a plastic member having functions of insulating and fixing the metal terminal, and a protection structure for protecting the plastic member, the metal terminal, and the locking portion, and the protection structure may be a metal armor. For example, the first base 10 may include a first metal terminal 18 and a first protection structure 19 provided on the first base body 11, and the first protection structure 19 may be provided outside the first locking portion 12 to protect the first locking portion 12. The second chassis 20 may include a second metal terminal 28 and a second protection structure 29 provided at the second chassis body 21, and the second protection structure 29 may be provided at an outer portion of the second locking portion 22 to protect the second locking portion 22. Further, the first base 10 may further include at least one first metal member 17, which may play a role in fixing and reinforcing the structural strength. The first metal fitting 17 may be provided between the first locking portion 12 and the unlocking portion 13, or may be provided at a position where structural strength needs to be reinforced. The second base 20 may further include at least one second metal member 27, which may serve to fix and reinforce the structural strength. The periphery of the second base body 21 may be provided with at least one mounting groove 26, and the second metal member 27 may be disposed in the mounting groove 26, or may be disposed at other positions where the structural strength needs to be reinforced. In the example shown in fig. 4, four mounting grooves 26 are provided on the outer periphery of the second chassis body 21, and the second metal member 27 may be disposed in the mounting grooves 26.
In some alternative embodiments, the first locking portion 12 is provided in a plurality, and is disposed along the circumferential direction of the first base body 11. Accordingly, the second locking portions 22 correspond to the number of the first locking portions 12, and are provided corresponding to the first locking portions 12 in the circumferential direction of the second base body 21. The unlocking portions 13 correspond to the number of the second locking portions 22, and are provided along the circumferential direction of the first base body 11 corresponding to the second locking portions 22. Like this, through setting up a plurality of first locking parts 12, a plurality of second locking parts 22 and unblock portion 13, first base 10 pegs graft with second base 20 and targets in place the back, and a plurality of first locking parts 12 respectively with the mutual hasp cooperation of corresponding second locking part 22, can promote the grafting steadiness of first base 10 and second base 20. When the first base 10 needs to be detached from the second base 20, the unlocking portion 13 may unlock and separate the corresponding second locking portion 22 from the corresponding first locking portion 12. As shown in fig. 4, in the illustrated example, two first locking portions 12 are provided on opposite sides of the first chassis body 11 in the first direction X. The two second locking portions 22 are respectively disposed on two opposite sides of the second base body 21 along the first direction X. The two unlocking portions 13 are provided at positions corresponding to the second locking portions 22 on opposite sides of the first base body 11 in the first direction X. Of course, in other examples, the first locking portion 12 may be in other numbers, which the present disclosure does not limit.
Referring to fig. 5 and 6, in some alternative embodiments, the first locking portion 12 includes a locking slot 121. Referring to fig. 7 to 9, the second locking portion 22 includes a locking main body 221 and an elastic bending portion 222 connected to the locking main body 221, and the locking main body 221 and the elastic bending portion 222 enclose to form a receiving portion 24. As shown in fig. 4, fig. and fig. 8, after the first base 10 is inserted into the second base 20, the elastic bending portion 222 is clamped in the locking groove 121, and the unlocking portion 13 is located in the accommodating portion 24 and abuts against the elastic bending portion 222. In this embodiment, the first locking portion 12 may be a plastic member, and the locking groove 121 may be a plastic groove, so as to reduce the structural weight. The locking groove 121 may be a groove in the shape of an oblique angle groove, a circular angle groove, an arc-shaped groove, a rectangular groove, or the like. It should be noted that the locking groove 121 may have other shapes, and the disclosure is not limited thereto.
In this way, when the unlocking portion 13 moves along the first direction X, the elastic bending portion 222 can be driven to move in a direction away from the locking groove 121, so that the elastic bending portion 222 is separated from the locking groove 121. When the first base 10 needs to be removed from the second base 20, as shown in fig. 4, the unlocking portions 13 located on the left side are moved rightward in the first direction X, the unlocking portions 13 located on the right side are moved leftward in the first direction X, and each unlocking portion 13 drives the elastic bending portion 222 of the corresponding second locking portion 22 to move in a direction away from the locking groove 121 of the corresponding first locking portion 12, so that the corresponding elastic bending portion 222 is separated from the corresponding locking groove 121, and the first locking portion 12 and the corresponding second locking portion 22 are unlocked, so that the first base 10 can be removed from the second base 20.
In some alternative embodiments, as shown in fig. 5, the locking groove 121 is disposed on an outer wall of the first chassis body 11. As shown in fig. 3, 7 and 8, the second base body 21 is provided in a housing cavity 23 for housing the first base body 11, and the second locking portion 22 is provided on an inner wall of the housing cavity 23. Referring to fig. 12 to 14, in the process of inserting the first base 10 into the second base 20, as shown in fig. 12, the first base 10 is not yet in contact with the second base 20, and the first base 10 moves downward to be inserted into the second base 20. As shown in fig. 13, when the first base 10 moves to the first position, the elastic bending portion 222 abuts against the outer wall of the first base body 11 and deforms. It can be understood that the outer wall of the first base body 11 presses the elastic bending portion 222 outwards to deform. As shown in fig. 14, when the first base 10 is moved to the second position, the first base 10 is inserted into the second base 20. It can be understood that, after the first base 10 is inserted into the second base 20, that is, the position of the elastic bending portion 222 corresponds to the position of the locking groove 121, the elastic bending portion 222 recovers to deform under the action of the elastic restoring force, and the elastic bending portion 222 recovers to the original position inwards and is clamped in the locking groove 121, so that the first base body 11 and the second base body 21 are fixed to each other, thereby completing the insertion and fixation of the first base 10 and the second base 20.
Referring to fig. 5, in some alternative embodiments, the first base body 11 is provided with a sliding cavity 14, and the unlocking portion 13 is slidably disposed in the sliding cavity 14 along the first direction X. In this way, the unlocking portion 13 can slide in the first direction X relative to the first base body 11. It will be appreciated that the receiving cavity 23 may include a bottom and sides. In the illustrated example, the sliding cavity 14 may extend along the first direction X, the first base body 11 may be a rectangular parallelepiped structure, the second base body 21 may be a rectangular parallelepiped structure, and the accommodating cavity 23 may be a rectangular parallelepiped groove structure adapted to the first base body 11. After the first base 10 and the second base 20 are inserted and fixed, the first base body 11 is accommodated in the accommodating cavity 23 of the second base body 21.
Further, in some optional embodiments, the first base body 11 defines a first opening 15. The side walls of the first opening 15 on opposite sides along a third direction Z perpendicular to the first direction X and the second direction Y are respectively provided with the sliding cavities 14. Referring to fig. 10 and 11, the unlocking portions 13 are respectively provided with sliding portions 131 on two opposite sides along the third direction Z, the unlocking portions 13 are provided in the first opening portions 15, and the sliding portions 131 are slidably provided in the same sliding cavities 14. In this way, the unlocking portion 13 is slidably engaged with the sliding cavities 14 on the same side by the sliding portions 131 on both sides, so that stability of the unlocking portion 13 during sliding can be improved.
In some alternative embodiments, the unlocking portion 13 is opened with a second opening 132, and the second opening 132 penetrates the unlocking portion 13 along the second direction Y. Thus, when the first base 10 needs to be detached from the second base 20, the user can directly toggle the unlocking portion 13 to move, or can insert the rod structure jig such as the thimble into the second opening portion 132, and then toggle the thimble to drive the unlocking portion 13 to move, so that the unlocking portion 13 or the corresponding external jig can be opened.
Referring to fig. 9, in some alternative embodiments, two elastic bending portions 222 are connected to two opposite sides of the latch main body 221 along a third direction Z, where the third direction Z is perpendicular to the first direction X and the second direction Y. One end of the elastic bending portion 222 is connected to the latch main body 221, the other end of the elastic bending portion 222 is bent toward the other elastic bending portion 222 relative to the latch main body 221, and the two elastic bending portions 222 and the latch main body 221 enclose to form the accommodating portion 24. Thus, the elastic bending portion 222 is bent towards the other elastic bending portion 222 relative to the latch main body 221, so that when the first base 10 moves to the first position, the elastic bending portion 222 abuts against the outer wall of the first base body 11, and the elastic bending portion 222 can deform. Optionally, the elastic bending portion 222 is in a straight structure or an arc structure relative to the latch main body 221, and can be better abutted and matched with the unlocking portion 13 and the outer wall of the first chassis body 11. Of course, the elastic bending portion 222 may have other shapes, which is not limited by the present disclosure. In this embodiment, the elastic bending portion 222 and the latch main body 221 may be integrally formed, so as to facilitate processing. The elastic bending portion 222 may be a metal member, which can enhance the structural strength and improve the locking strength between the first locking portion 12 and the second locking portion 22. The latch main body 221 may be a metal member, which can enhance the structural strength and improve the locking strength between the first locking portion 12 and the second locking portion 22.
Referring to fig. 10 and 11, in some alternative embodiments, an end surface of the unlocking portion 13 for abutting engagement with the elastic bending portion 222 is provided with a first guiding surface 133, which can guide the unlocking portion 13 when the unlocking portion 13 moves. In this way, the unlocking portion 13 can be brought into contact with and engaged with the elastic bent portion 222 via the first guide surface 133, and the unlocking portion 13 can be moved more smoothly. Referring to fig. 12, the end surface of the outer wall of the first chassis body 11, which is used for being abutted and matched with the elastic bending portion 222, is provided with a second guiding surface 16, which can guide the first chassis body 11 in the process of inserting the first chassis body 11 into the second chassis body 21. Thus, the first base body 11 can better engage with the elastic bending portion 222 through the second guide surface 16, so that the deformation process of the elastic bending portion 222 is smoother. Referring to fig. 12, an end surface of the elastic bending portion 222, which is used for being abutted against and matched with the first chassis body 11, is provided with a third guiding surface 223, which can guide the first chassis body 11 in the process of inserting the first chassis body 11 into the second chassis body 21. Thus, the elastic bending portion 222 can better engage with the first base body 11 through the third guide surface 223, so that the deformation process of the elastic bending portion 222 is smoother.
Optionally, the first guiding surface 133 may be an inclined surface or an arc surface, and may achieve a better abutting cooperation effect with the elastic bending portion 222. The second guide surface 16 may be a slope or an arc. Can achieve better abutting matching effect with the elastic bending part 222. The third guide surface 223 is an inclined surface or an arc surface, and can achieve a better abutting matching effect with the first base body 11.
