Embodiment
See also Fig. 2 (a), 2 (b) and 2 (c), the signal connector 2 surface structure schematic diagrames that Fig. 2 (a), 2 (b) and 2 (c) develop for the deficiency of improving conventional apparatus, and signal connector 2 proposed by the invention mainly is to be applied in the process that signal connector 2 and circuit board 3 are assembled.Shown in Fig. 2 (a), we can find out clearly that this signal connector 2 consists predominantly of body 20 from figure, junction surface 21, first protuberance 22 and second protuberance 23, wherein this body 20 provides coaxial cable (not shown at this) to be electrically connected, this junction surface 21 then includes first composition plane 211 and second composition plane 212 that is connected on this body 20, this junction surface 21 utilizes this first composition plane 211 to engage assembling with this second composition plane 212 with this circuit board 3, and topmost this first protuberance 22 and this second protuberance 23 that is connected on this first composition plane 211 that this junction surface 21 comprises and this second composition plane 212 that be characterised in that of signal connector of the present invention 2, when this signal connector 2 is assembled with this circuit board 3, in the prior art, this conventional apparatus is to utilize composition plane to cooperate upper surface mounting technology (SMT) and this circuit board 3 to assemble, the situation that has mechanism's undercapacity takes place, so signal connector 2 of the present invention except this first composition plane 211 of utilizing junction surface 21 and being comprised and this second composition plane 212 with this circuit board 3 engages, also on this first composition plane 211 and this second composition plane 212, increased the structure of this first protuberance 22 with this second protuberance 23, therefore, when this signal connector 2 is assembled with this circuit board 3, this first protuberance 22 can further make this body 20 can more firmly be fixed on this circuit board 3 to strengthen the intensity of mechanism with this second protuberance 23, with this coaxial cable (in that this is not shown) when plugging repeatedly, do not have this signal connector 2 and take place, and then improve the not enough of conventional apparatus and reach the topmost purpose of the present invention with the situation that this circuit board 3 breaks away from.Below do further explanation with regard to signal connector 2 of the present invention again.
Shown in Fig. 2 (b), we can clearly be seen that from figure, when this signal connector 2 when assembling with this circuit board 3, because this first protuberance 22 that is connected in this first composition plane 211 and this second composition plane 212 and this second protuberance 23 are to be 90 with this first composition plane 211 and this second composition plane 212 to spend vertical leg structure (can certainly be other angle, spending with 90 in this explanation vertically is example), so we are just offering on this circuit board 3 after first through hole 301 with respect to this first protuberance 22 and this second protuberance 23 provides this first protuberance 22 to pass with this second protuberance 23 with second through hole 302, and then make the polarization increase of body 20 on this circuit board 2 of this signal connector 2.So when this signal connector 2 passes through this first composition plane 211, this second composition plane 212 with these circuit board 3 plane engagement, this first protuberance 22 just can pass this first through hole 301 and this second through hole 302 that is had on this circuit board 3 with this second protuberance 23, utilizing surface mounting technology (SMT) to make mutual the welding or stick together of 3 of the junction surface 21 of this signal connector 2 and this circuit boards with welding manner or bonding mode at last, this signal connector 2 and surface structure after this circuit board 3 engages are then shown in Fig. 2 (c).
In addition; we also can clearly find from Fig. 2 (b) and 2 (c); this first composition plane 211 that this junction surface 21 is comprised and the length of the length of this second composition plane 212 greater than this body 20; so can increase the area that is welding or sticking together between this signal connector 2 and this circuit board 3; in addition; this first protuberance 22 mainly is to be connected on first end 2101 of this first composition plane 211 and this second composition plane 212 with this second protuberance 23; and usually the position that on this body 20, plugs of this coaxial cable (in that this is not shown) at second end 2102 places (direction as in figure arrow shown in) of this first composition plane 211 with this second composition plane 212; therefore; under the situation of length greater than the length of this body 20 of this first composition plane 211 and this second composition plane 212; this coaxial cable (not shown) and this first protuberance at this; moment between this second protuberance just can increase; because the user is when plugging this signal connector 2; through regular meeting the excessive situation of strength of plug takes place, so the increase of moment can reduce the user causes the disengaging damage of 3 of this signal connector 2 and this circuit boards in the plug to these signal connector 2 improper application of forces possibility.
Comprehensive above-mentioned technical descriptioon, the topmost feature of signal connector 2 of the present invention be exactly this first composition plane 211 of being comprised at this junction surface 21 with this second composition plane 212 on be connected with this first protuberance 22 and this second protuberance 23, when this signal connector 2 and this circuit board 3 carry out surface applying assembling, this first protuberance 22 just can pass on this circuit board 3 according to this first protuberance 22 with this second protuberance 23,23 corresponding these first through holes 301 and this second through hole 302 of offering of this second protuberance, thus, just can improve the number of times of these signal connector 2 connect-disconnect lives and the polarization between this signal connector 2 and this circuit board 3, and then improve deficiency on the conventional apparatus, finish topmost purpose of the present invention.Above-described this signal connector 2 is not only to limit the signal connector that is used in single kind; as the superminiature radio frequency connector of being mentioned in the prior art (MMCX); and technological thought of the present invention more can be applied on the process of little shape radio frequency connector (MCX) and Miniature RF connector signal connectors such as (as: SMA, SMB, SMC) 2 and circuit board 3 assemblings widely; therefore; the present invention must be appointed by those skilled in the art and executes that the craftsman thinks and be to modify as all, the scope of right neither disengaging claims institute desire protection.
