Referring to fig. 1 and fig. 2, fig. 1 is a schematic perspective view of a guided board-to-board connector according to some embodiments of the utility model. The guided board-to-board connector with floating function comprises: the first board connection assembly 100 and the second board connection assembly 200 for interfacing with the first board connection assembly 100.
The first board connection assembly 100 includes: the first base 110, the floating connection base 120 and a plurality of first terminals 130. The first housing 110 is fixed to the first plate 101. The top of the first housing 110 has a window 111. The inner space formed by the wall surface of the first base 110 and the first plate 101 is accessible through the window 111. At both ends of the first seat 110, adjacent to the window 111, first guide portions 112 are respectively disposed. In the embodiment of fig. 1 and 2, the first guide portion 112 is exemplified by a guide hole.
The first seat 110 is formed with corresponding limit rails 113 between the two ends of the window 111 and each first guide portion 112. The wall width of the side walls of the curb rail 113 may be used to define the movable extent of the floating link 120 to eliminate misalignment and reduce plate-to-plate stress. The floating connection base 120 is mounted on each of the limit rails 113 by the bottom surface of the limit rail 113, and thus the floating connection base 120 disposed on the first base 110 and having mobility is formed.
The first terminals 130 are fixed to the first board 101 and extend upward to penetrate the floating connection base 120. Each of the first terminals 130 is configured to have a predetermined distance D1, and the predetermined distance D1 refers to a distance between the first terminal 130 and the first board 101 on an end far from the first board 101.
In addition, the first board connection assembly 100 may be further fastened to the first base 110 by the fastening member 140 to limit the floating connection base 120 in the limit rail 113, so as to further avoid the floating connection base 120 from being separated.
The second board connection assembly 200 includes: the second housing 210 and a plurality of second terminals 230. The second housing 210 is fixed to the second plate 201. The second terminal 230 is fixed to the second board 201 and penetrates the second base 210. When the second board connection assembly 200 is docked with the first board connection assembly 100, the second housing 210 is configured to dock with the floating connection 120 to form a joined structural configuration. The second base 210 is provided at both ends thereof with second guide portions 212 for matching with the first guide portions 112, respectively. In the embodiment of fig. 1 and 2, the second guiding portion 212 is exemplified by a guide post.
It is to be noted that, in other embodiments, the first guiding portion 112 may be a guide post, and the second guiding portion 212 is a guide hole. Further, it may even be that one of the two first guiding portions 112 on the first base 110 is a guide post, and the other is a guide hole, and as a corresponding matching configuration, one of the two second guiding portions 212 on the second base 210 is a guide hole, and the other is a guide post.
Referring to fig. 1 to 3, fig. 3 is a schematic cross-sectional view of a guided board-to-board connector according to some embodiments of the utility model. The guide post (the second guide portion 212) is a column-shaped structure protruding toward the butt-joint direction (i.e. the direction of the first seat 110), and a column is taken as an example in fig. 1 to 3, but not limited thereto. The guide hole (first guide 112) is used for receiving and accommodating the guide post (second guide 212). The guide post (second guide 212) has a post length D2, and the post length D2 is at least 2/3 of the predetermined distance D1.
In some embodiments, the post length D2 exceeds the predetermined distance D1. When the first board connecting assembly 100 is joined to the second board connecting assembly 200, each guide post (the second guide portion 212) may be used to provide at least half of the post length D2 to be immersed into the corresponding guide hole (the first guide portion 112) when each first terminal 130 initially contacts the corresponding second terminal 230. That is, before the second base 210 is disposed with the second terminal 230 and contacts the floating connection base 120 of the first base 110, the guiding post (the second guiding portion 212) of the large guide contacts the matching guiding hole (the first guiding portion 112) to generate guiding effect.
In some embodiments, the leading edge of each guide post (second guide 212) has a taper 2121. The radius of each guide post (second guide 212) may be configured to be substantially the same as a maximum correctable offset distance between the first and second board connection assemblies 100 and 200. That is, when the maximum allowable deviation between the first board connecting assembly 100 and the second board connecting assembly 200 is set (exceeding the deviation, i.e., being abnormal, not in the conventional assembly state), the radius of the guide post (the second guiding portion 212) is correspondingly determined to enhance the guiding effect during the installation.
As shown in fig. 3, the first guide portion 112 is a guide hole, and each guide hole penetrates through the first base 110, and two through holes 102 corresponding to each guide hole (the first guide portion 112) are formed in the first plate 101. The second guiding portion 212 is a guiding post, and each through hole 102 is used for providing a receiving space of the tapered portion 2121 of the corresponding second guiding portion 212 (guiding post). In other words, the guide post can be further lengthened to extend to the first plate 101, so that the convenience, accuracy and stability of alignment and installation are further improved.
Referring next to fig. 4, a schematic longitudinal cross-section of a guided board-to-board connector according to some embodiments of the utility model is shown.
The first board 101 is arranged with a plurality of first terminals 130 (as shown in fig. 2), wherein the first terminals 130 are made of metal strips or metal plates, each first terminal 130 is sequentially extended from one end fixed on the first board 101 to form a first bending portion 131 and a second bending portion 132, and the second bending portion 132 is closer to the surface of the first board 101 than the first bending portion 131. As can be seen from the first terminal 130 on the left side in fig. 4, the first bending portion 131 and the second bending portion 132 are formed by bending the first terminal 130, so that the first terminal 130 near the first board 101 forms an N-shape, and the first terminal 130 on the right side in fig. 4 forms a mirrored N-shape at the first bending portion 131 and the second bending portion 132. Therefore, the bending structures of the first bending portion 131 and the second bending portion 132 can increase the elasticity of the first terminal 130 and provide force compensation when being deformed under force.
The first terminal 130 may have an angle (e.g., the angles θ1 and θ2 illustrated in fig. 4) smaller than 20 degrees and larger than 5 degrees at the positions of the first bending portion 131 and the second bending portion 132. In the present embodiment, the angles of the first bending portion 131 and the second bending portion 132 are substantially the same (the angles of θ1 and θ2 are substantially the same), and are illustrated as about 17 degrees in fig. 4. However, the angle formed by the first terminal 130 at the position of the first bending portion 131 and the second bending portion 132 may be different.
In summary, the matching between the guide post and the first terminal (on the vertical length between the guide post and the board body) provides accuracy and convenience for mounting the board-to-board connector, and the use of the floating connecting seat also improves the stability of electrical connection. Still further, through the first bending portion and the second bending portion on each first terminal, the floating connecting seat can provide more excellent electric connection stability, and under the collocation of the guide post with big guide, the whole board-to-board connector with floating function has better guide effect when counterpointing and inserting, and is applicable to the terminal with great bending degree, and then after counterpointing and jointing, the broken signal risk when having avoided vibrations or impact.
While the utility model has been disclosed in terms of preferred embodiments, it will be understood by those skilled in the art that the embodiments are merely illustrative of the utility model and should not be construed as limiting the scope of the utility model. It should be noted that all changes and substitutions equivalent to those of the embodiments are intended to be included in the scope of the present utility model. Accordingly, the scope of the utility model is defined by the appended claims.
