Description
(1) technical field
The relevant a kind of floating connector assembly of the present invention particularly is connected in the connector of circuit board about a kind of with the spring-piece type spring, so that carry out displacement by a small margin on circuit board, and makes things convenient for the pin combination corresponding with peripheral element of this connector.
(2) background technology
Step along with the production of integrated circuits rapid technological improvement, development and progress that electronics technology continues make chipset and processor of new generation, have possessed more meticulous, complicated internal wiring framework, and more powerful operation capacity can be provided, with more complicated operating function.Particularly,, therefore be used in large quantities in the electronic multimedia product, and be subjected to general the liking and use widely of society consumer because it can handle digitalized datas such as various audios, image, pattern easily.
With present common on the market PS2 game machine, because it has possessed central processing unit (Emotion Engine) and the high-order drafting processor made from 0.13 micron system (Graphics Synthesizer), therefore suitable exquisiteness and smooth picture effect can be provided, and be subjected to consumer's welcome.In order to continue to promote the performance of game machine, relevant dealer also constantly releases peripheral equipment miscellaneous, provides the consumer to choose, so that further promote the usefulness of game operation, provides more operating function and selection.In vogue along with online game particularly, each tame manufacturer also releases the peripheral product that the game machine of arranging in pairs or groups is surfed the Net successively.With the PS2 game machine is example, and the consumer can buy the modem product of a box shape, and by connector its assembling is linked on the game machine back panel.Like this, just, can surf the Net or carry out the recreation of networking line by this modem.
Please refer to Fig. 1, this figure has shown the modem 1 that present PS2 game machine is arranged in pairs or groups.On the modem 1 of box shape, have three connectors 11,12 and 13, can be when being assembled in the game machine back, motherboard (not shown) and the hard disk 2 with game machine produces signal and electrically connect respectively.As shown in FIG., the connector 11 that is positioned at modem 1 upside is to be used for linking with motherboard, to transmit relevant instruction and information.As for the connector 12 and 13 that is positioned at modem 1 downside, then be used for game machine in hard disk 2 link.Wherein, signal connector 12 is to be used for combining with the signal pin 22 of hard disk 2 rear sides, transmits relevant signal and data.As for power connector 13, then be used for combining, so that receive required electric power with the power pin 23 of hard disk 2 rear sides.
It should be noted that in order to increase the compatibility of hardware the PS2 game machine there is no for some dimensions of hard disk and carries out strict restriction at present, for example the distance of 23 of signal pin 22 and power pins does not promptly have standard.Therefore, the various hard disk of the big factory of each hard disk manufacturing now all can be assembled in the game machine that applies to PS2.Yet, like this because the disunity of hard disk specification, make this and the modem of game machine collocation, the considerable difficulty of on assembling, having derived.Particularly, because be assembled in the hard disk 2 in the game machine, may be locked on the casing of the side that keeps left, also may be locked on the casing on the right side, and each tame hard disk 2 its signal pin 22 also equates not to the utmost with power pin 23 distance to each other, therefore how determination data machine 1 its connector 11,12 and 13 relative position for game machine manufacturer, obviously are individual very stubborn problems.
In order to solve the contraposition problem of above-mentioned connector 11,12 and 13, in the product of present modem 1, except the connector 11 that is used for combining with motherboard has the fixed position, the signal connector 12 that is used for combining with hard disk 2 all is designed to carry out the movable structure that left and right sides small distance is offset with power connector 13, so that can carry out the adjustment and the correction of contraposition along with the difference of each label hard disk specification.It should be noted that, because the design of this kind movable structure, be that connector 11,12 and 13 is made in respectively on three different circuit boards, therefore except the considerable spare part of needs, and cause outside the increase of production cost, the assembling process that it is numerous and diverse also can significantly elongate the whole manufacturing cycle, and be unfavorable for the lifting of production capacity.
Please refer to Fig. 2 and Fig. 3, these two accompanying drawings have shown the modem 1 internal structure design of present known connector.As above-mentioned, because connector 11,12 and 13 is made in respectively on three different circuit boards, therefore in the casing of modem 1, still needs and prepare an extra fixed frame 15, each circuit board that is used for locking is assembled in the product housing 17 of modem 1 again.Please earlier with reference to Fig. 2, this figure has shown assembling signal connector 12 required assembly on fixed frame 15.Wherein, being used for the connector 11 that links with the game host plate, is directly to be fixed on the main circuit plate 110 with surface mount technology (SMT).As shown in FIG., this main circuit plate 110 has bigger size, and close with fixed frame 15 opening sizes, and can directly engage and be locked in fixed frame 15 its sidewalls around the space in.
Be not difficult to find out by top description, according to current design, in order to make signal connector 12 can carry out the adjustment of small distance, make the circuit board 120 of a collocation signal connector 12 except needs are extra, still needing increases above-mentioned fixed frame 15, fixed head 121, rivet 121a and 121b, fixed screw 122a and 122b, and assembling and material cost are improved relatively.In addition, for the circuit board 120 that makes signal connector 12 places can produce required electrically connect with main circuit plate 110, on main circuit plate 110 and circuit board 120, be equiped with winding displacement joint 110a and 120a respectively, so that both are linked together by a flexible flat cable (FFC cable) 123.But on the whole production cost, obviously also want the expense of two winding displacement joints of added burden and a flexible flat cable, and whole assembling process also becomes quite complicated like this.
Except signal connector 12, the design of power connector 13 is also quite complicated.Please refer to Fig. 3, this figure has shown the situation of assembling power connector 13 on fixed frame 15.For make power connector 13 can about the skew carry out the adjustment of position, also can additionally make a circuit board 130 that size is less, be used for combining with power connector 13.And, installed a fixed head 131 at the lower surface of circuit board 130.Similarly, have rivet 131a separately,, pass the hole of power connector 13 and circuit board 130 from top to bottom in regular turn, it is locked on the rivet 131a of fixed head 131 so that by two fixed screw 132a at the two ends, the left and right sides of fixed head 131.In addition at fixed head 131 central parts, and has a rivet 131b, just in time corresponding to the hole 152 on fixed frame 15 side plates.By with fixed screw 132b, pass hole 152 from lower to upper and be locked in rivet 131b, fixed head 131 can be fixed on the fixed frame 15.Because hole 152 has larger aperture, but so the moving of fixed head 131 small distances, and reach the effect of adjusting power connector 13 positions.
For producing with main circuit plate 110, the circuit board 130 that makes power connector 13 places links, on main circuit plate 110 and circuit board 130, and can install signal connector 110b and 130a respectively, so that both are linked together by a bars tie line 133.But this kind design, except the circuit board 130 of a collocation of needs power connector 13, still need fixed frame 15, fixed head 131, rivet 131a and 131b, fixed screw 132a and 132b, extra signal connector 110b and 130a, with the signal tie line 133 that links usefulness, obviously neither to one's profit on assembling and material cost, the program of assembling is also too complicated.
In other words, modular construction according to present modem 1, though can generally adjust the position of signal connector 12 and power connector 13, and with game machine in the signal pin 22 of hard disk 2 or the requirement that power pin 23 reaches accurate contraposition, but as above-mentioned, owing to adopted the different circuit board of three block sizes, difference carrying signal connector 12, power connector 13 and main frame link head 11, and Da Pei assembly is quite numerous and diverse again separately, no matter therefore be production cost or making assembly program, the neither demand that meets economic benefit.

Owing to do not need among the present invention to come framework assembling floating connector by circuit board separated from one another, so all connector among the present invention, all can be made on the same circuit board.Please refer to Fig. 4, this figure has shown first embodiment that makes floating connector 4 among the present invention on circuit board 3.As shown in FIG., this floating connector 4 is to be a power connector, can be used for combining with the power pin at the hard disk back side, so that its required electric power to be provided.At the lower surface of floating connector 4, have the groove 41 of a plurality of depressions, and in each groove 41, be provided with one group of spring-piece type spring 42.When floating connector 4 was assembled on the circuit board 3, each group spring-piece type spring 42 just in time can be pressed and touch corresponding pad 31 on circuit board, and be made floating connector 4 and circuit board 3 produce electrically connect.
In addition, two ends at floating connector 4, then has opening respectively, for example be circular or " U " type opening 43 that inwardly concaves, with U opening 43 is example, when assembling floating connector 4 is on circuit board 3, and can be with two fixed screws 44 that pass U type opening U type opening 43, be limited to screw 32 corresponding on the circuit board 3, and 4 assemblings of floating connector are fixed on circuit board 3 surfaces.At this moment, the spring-piece type spring 42 of floating connector 4 lower surfaces just in time can be pressed and touch in circuit board 3 upper surface corresponding pad 31, and required electrically connect is provided.
What particularly point out is that the fixed screw 44 of restriction floating connector 4 on circuit board 3 can be divided into the marginal ridge 44c of upside, the cylinder position 44a in stage casing and the thread 44b of downside.Wherein, the diameter of marginal ridge 44c is greater than the diameter of the internal diameter of the circular arc portion of U type opening 43 and the cylinder position 44a internal diameter less than U type opening 43 circular arc portions.In addition, the length of cylinder position 44a is greater than the thickness of U type opening 43.When locking action, the thread 44b of downside can screw in the screw 510 corresponding on the product housing 500 so that circuit board 3 is locked in housing 500 via the screw 32 of circuit board 3; Then can be subjected to the restriction of U type opening U type opening 43 as for cylinder position 44a, and reach the fixedly purpose of floating connector 4, in addition, because the diameter of marginal ridge 44c greater than the internal diameter of U type opening 43 circular arc portions, can not break away from circuit board 3 it so also can press restriction floating connector 4.Because this kind fixed screw 44 cooperates the locking mode of U type opening 43, the floating space of these floating connector 4 one horizontal directions can be provided by the difference of the internal diameter of the diameter of cylinder position 44a and U type opening 43 circular arc portions, is not with tightly locked on circuit board 3 of floating connector 4.Add the thickness of the length of cylinder position 44a greater than U type opening 43, therefore in practice, can allow floating connector 4 on circuit board 3, to carry out upper and lower displacement, also allow it on the plate face of circuit board 3, to carry out clockwise in addition or carry out the distortion displacement of trace counterclockwise perpendicular to circuit board 3 plate faces.In addition, the depth by adjusting fixed screw 44 position in U type opening 43 also can make floating connector 4 carry out left and right displacement by a small margin, adjusts the purpose of floating connector 4 with respect to circuit board 3 positions and reach.
Because spring-piece type spring 42 has the distortion bending ability of certain degree, therefore when floating connector 4 with respect to circuit board 3 by a small margin during displacement, each group spring-piece type spring 42, still can press closely and touch corresponding pad 31 on circuit board 3, and can guarantee under the condition that electrically connect obtains to keep, allow floating connector 4 carrying out horizontal direction (about, front and back), vertical direction (up and down) on the circuit board 3 even along counterclockwise adjustment by a small margin.
Except above-mentioned mode of connection, provided by the present inventionly carry out the design of electrically connect with the spring-piece type spring, also can be used in the connector with a large amount of intensive pins, for example signal connector.Please refer to Fig. 5, this figure has shown according to second embodiment of the invention, makes the mode of floating connector assembly on circuit board 3.As shown in FIG., the floating jockey has comprised optionally circuit flap 7 of a signal connector 5 with intensive pin, a spring-piece type spring connector 6 and herein, can be used for combining, to transmit required signal and data with the signal pin at the hard disk back side.Wherein, the lower surface of spring-piece type spring connector 6 has a plurality of pins 61, and for example the SMT pin corresponds respectively to a plurality of weld pads 33 on the circuit board 3.As for upper surface, then made many groups spring-piece type spring 62 of dense arrangement at spring-piece type spring joint 6.These spring-piece type springs 62 are via intraconnections, and are connected to the pin 61 of lower surface correspondence.Wherein, this spring-piece type spring connector 6 can be assembled by the mode of welding and be fixed on the circuit board 3, makes the SMT pin 61 of lower surface be directly connected in corresponding pad 33 and produce required electrically connect.Or the upper surface of spring-piece type spring connector 6 has a plurality of pins 61, at the lower surface of spring-piece type spring joint 6, has then made many groups spring-piece type spring 62.
For the ease of understanding the detailed structure of above-mentioned spring-piece type spring connector 6, please refer to Fig. 5 A and Fig. 5 B.Wherein, in Fig. 5 A, the upper surface of spring-piece type spring connector 6 is many groups spring-piece type springs 62 of having made described dense arrangement; As in Fig. 5 B, the lower surface of spring-piece type spring connector 6 has then been made a plurality of SMT pins 61, is used for being connected with weld pad 33 on the circuit board 3.
At the small jack 51 that the upper surface of signal connector 5 has a plurality of dense arrangement, be used for engaging with the signal pin of hard disk rear side; And the lower surface of signal connector 5, the pin 52 that then has a plurality of dense arrangement.Same, be positioned at the interconnector of pin 52 meetings of lower surface, and be connected to corresponding small jack 51 via signal connector 5.Like this, when carrying out the assembly program of floating connector assembly, can directly signal connector 5 be pressed on the upper surface of spring-piece type spring connector 6.At this moment, correct before each spring-piece type spring 62 of spring-piece type spring connector 6 to press and touch corresponding pin 52, and make signal connector 5 and spring-piece type spring connector 6 produce electrically connect.Under this kind situation,, can allow signal connector 5 to carry out the displacement by a small margin of horizontal direction and vertical direction with respect to circuit board 3 by spring-piece type spring 62 its distortion bending abilities.
It should be noted that signal connector 5 its pin sizes are quite tiny and arrange quite intensively, in comparison, the spring-piece type spring size of spring-piece type spring connector 6 just seems excessive, and is difficult to arrange to such an extent that picture is intensive as the pin 52.For head it off, optionally increase a circuit flap 7.As shown in FIG., the pin pattern 71 that these piece circuit flap 7 upper surfaces have a plurality of dense arrangement is as for then made the comparatively loose pin pattern 72 of a plurality of arrangements at the lower surface of circuit flap 7.Wherein, the first pin pattern 71 has less size, and its arrange between apart from identical with the pin 52 of signal connector 5, therefore can directly be attached at signal connector 5 lower surfaces, each first pin pattern 71 is linked together with corresponding pin 52; Relative, 72 in the second pin pattern has bigger size, and distance was identical with the spring-piece type spring 62 of spring-piece type spring connector 6 between it was arranged, therefore when being attached at spring-piece type spring connector 6 upper surfaces, each second pin pattern 72 just in time can touch with corresponding spring-piece type spring 62.
In addition, made " U " type opening 73 that inwardly concaves respectively, can it be fixed on the circuit board 3 to pass the fixed screw 53 of U type opening 73 at the two ends of this circuit flap 7.When the assembly program of being correlated with, be earlier signal converting head 5 to be fixed in circuit flap 7 upper surfaces in the mode of welding, to produce required electrically connect effect.As for, spring-piece type spring connector 6 as mentioned above, also can be fixed on the circuit board 3 by the mode of welding, and produces required electrically connect.Then, can be locked in screw 34 corresponding on the circuit board 3, and signal connector 5 and 7 assemblings of circuit flap are fixed on circuit board 3 surfaces by using two fixed screws 53 that pass U type opening 73.At this moment, the spring-piece type spring front end of spring-piece type spring connector 6 upper surfaces just in time can be pressed the pin pattern 72 that touches in circuit flap 7 lower surfaces, and required electrically connect is provided.
As above-mentioned, the fixed screw 53 of signal connector 5 on circuit board 3 that be used for locking can be divided into the marginal ridge 53c of upside, the cylinder position 53a in stage casing and the thread 53b of downside.Wherein, the diameter of marginal ridge 53c is greater than the diameter of the internal diameter of the circular arc portion of U type opening 73 and the cylinder position 44a internal diameter less than U type opening 73 circular arc portions.In addition, the length of cylinder position 53a is greater than the thickness of U type opening 73.Locking when action, the thread 53b of downside can be via the screw 34 of circuit board 3, and screws in the screw 52 corresponding on the product housing 5; Then can be subjected to the restriction of U type opening 73 as for the cylinder position 53a of upside, and reach the purpose of fixed signal connector 5 and circuit flap 7, and signal connector 5 also can carry out the upper and lower displacement perpendicular to circuit flap 7 on circuit flap 7.In addition, because the diameter of marginal ridge 53c can vertically not break away from circuit board 3 or circuit flap 7 it greater than the internal diameter of U type opening 73 circular arc portions so also can limit floating connector 5.Under this kind situation, signal connector 5 can carry out the upper and lower displacement perpendicular to circuit board 3 or circuit flap 7 on circuit board 3.Or by the depth of adjusting fixed screw 53 position in U type opening 73, and about signal connector 5 is carried out, front and back or displacement by a small margin up and down, to adjust distance or the position of signal connector 5 with respect to circuit board 3.
Please refer to Fig. 6, this figure has shown the mode of connection among above-mentioned two embodiment, has been applied to a situation on the main circuit plate 8.On this piece main circuit plate 8, except the power connector 9 of the signal connector 5 of installing floating and floating, also can install the main connector 81 of conventional fixed formula.Wherein, main connector 81 is to be used for producing electrically connect with a motherboard, to transmit required information and date.As for the signal connector 5 and power connector 9 of floating, then be to be used for producing binding with the signal pin and the power pin at hard disk back.Wherein, the mode of connection of signal connector 5, circuit flap 7 and spring-piece type spring connector 6 is identical with embodiment among above-mentioned Fig. 5.As for, the mode of connection of power connector 9, then similar to the embodiment among above-mentioned Fig. 4, be by the spring-piece type spring 92 in the power connector 9 lower surface recessed trench 91, touch with main circuit plate 8 upper surface corresponding pad 82, and produce required electrically connect.
It should be noted that a end, have " U " type opening 93 that inwardly concaves,, then have an outward extending projection 94 as for the other end at power connector 9 at this power connector 9.Populated circuit board 8 in product framework or shell the time, described projection 94 just in time can embed in the groove that is made of circuit board 8 and product framework or shell, as for 93 energy of described U type opening by using a fixed screw 44, power connector 9 is locked in screw corresponding on the circuit board 3, and its assembling is fixed on circuit board 8 surfaces.At this moment, spring-piece type spring 92 front ends of power connector 9 lower surfaces just in time can be pressed and touch in circuit board 8 upper surface corresponding pad 82, and required electrically connect is provided.Like this,, can make power connector 9 carry out displacement by a small margin, and adjust it with respect in the position of circuit board 8 with respect to circuit board 8 by adjusting the position of fixed screw 44 in U type opening 93.
