Fig. 2 has shown a kind of socket 2 disclosed by the invention.Socket comprises housing 3, has the passage 40 that allows plug 50 turnover in housing 3, the contact switch 20a-20d that has a plurality of (such as 4) along continuous straight runs to arrange above passage 40.Simultaneously, the right and left at passage 40 all is provided with contact switch 30a and the 30b that vertically arranges.Contact switch 20a-20d and 30a and 30b are set to contact with plug 50 when plug 50 admission passage 40, when plug 50 inserted and extracts described passage 40, the movement of plug 50 can be with moving contact switch 20a-20d to move up and down the move left and right with contact switch 30a-30b.

Fig. 3 has shown the exemplary configurations (switch 20a-20d can have identical structure) of a contact switch 20a.Switch 20a has

terminal

100a and 200a, and terminal 100a has a contact portion 110a and elastic arm 120a, and terminal 200a has contact portion 210a, and contact portion 110a is positioned at the top of contact portion 210a.When plug did not insert, contact portion 110a optionally contacted with contact portion 210a, and switch 20a is closed.Optionally, contact portion and elastic arm shape are elongated sheets as shown in the figure, and this shape is conducive to the strain of terminal, so that terminal has very strong durability, and are convenient to processing and manufacturing reduction cost.And, by the length of adjusting terminal and the performance that width can further improve strain, prolong its useful life.Optionally, terminal 200a can have elastic arm 220a as shown in Figure 3, and

terminal

100a and 200a have almost identical structure like this, is convenient to processing and manufacturing and reduces cost.

After plug 50 inserts socket 3 along passage 40, its below that is inserted into terminal 100a elastic arm 120a contacts with elastic arm 120a, the elastic arm 120a skew that can under the effect of plug 50 insertion forces, make progress, thus

contact portion

110a and 200a disengage, and switch 20a disconnects.Terminal 100a and 200a and plug 50 all comprise electric conducting material so that it when being in contact with one another, can realize being electrically connected.

Fig. 4 has more clearly shown as its terminal elastic arm of switch 20a of preferred embodiment and the details of contact portion.Have protruding 215a protruding upward on the contact portion of terminal 210a, contact portion 210a contacts with contact portion 110a by protruding 215a.Although do not show among the figure, be appreciated that also to be chosen in the projection that downward protrusion is set on the contact portion 110a, contact portion 110a contacts by this downward projection and contact portion 210a.It should also be understood that; although arrange to be raised with to be beneficial at

contact portion

110a or 210a and reduce two contacts area between the terminal; sensitiveer so that switch more easily disconnects after plug inserts, however protruding terminal is not set within protection scope of the present invention yet.In addition, the set-up mode of projection 215a also can be varied, as long as the projection that forms can realize above-mentioned effect, such as can being that downside punching press at contact portion 210a is so that be subjected to punch-out protruding upward, thereby the upside in contact portion forms protruding 215a, also can be that contact portion 210a integral body directly is bent upwards the formation projection, for example, by bending technique the contact portion 210a of terminal 200 upwards is bent to form protruding 215a, can also on contact portion, encloses in addition a projection (such as the metal bump of burn-oning); In like manner, it also is like this forming to lower convexity at contact portion 110a.

Optionally, elastic arm 120a also is provided with the protuberance 126a of downward protrusion, and the position of protuberance 126a is set to when plug 50 inserts passage, and plug 50 promotes described protuberance 126a, so that

contact portion

110a and 210a disengage.Downward protuberance 126a energy is set so that plug 50 promotes the elastic arm 120a of the first terminal more easily, sensitiveer thereby switch 20a more easily disconnects after plug 50 inserts.Protuberance 126a also can have the multiple set-up mode of similar above-mentioned protruding 215a, as long as the protuberance that forms can be realized the effect of above-mentioned protuberance.

Optionally, the contact portion 110a of terminal 100a also has upwards arcuate configuration 116a, and it can hold the end portion of terminal 200a as shown in the figure, and it helps

terminal

100a and 200a relative position setting in the horizontal direction.In the example depicted in fig. 3, by the contact portion 110a at terminal 100 one arcuate configuration 116a upwards is set, terminal 100a can be arranged on identical horizontal level with terminal 200a

elastic arm

120a, 220a separately.

Get back to now Fig. 3, terminal 100a optionally has from the vertically extending linking arm 130a of elastic arm 120a with from described elastic arm 220 vertically extending linking arm 230a; When terminal 200a did not have elastic arm 220a, linking arm 230a vertically extended from the contact portion 210a of terminal 200a.Certainly, linking arm also can out of plumb extend.By linking arm terminal 100 and 200 is fixed in the socket, the end of linking arm forms the stiff end of respective terminal, the strain that this structure helps elastic arm 120a to make progress when being subject to the insertion force of plug 50, the useful life of prolongation elastic arm.

Those skilled in the art it is also understood that,

terminal

100a and 200a also can not have linking arm, for example the elastic arm 220a of the elastic arm 120a of terminal 100a and terminal 200a (if do not have elastic arm then be contact portion 210a) separately the end relative with its free end form respectively the stiff end of

terminal

100a and 200a, directly be fixed in the housing 3.At least one benefit of this structure terminal is that the space of the passage 40 axial left and right sides can further be utilized more fully.

Optionally, the bearing of trend of the elastic arm 120a of terminal 100a and the elastic arm 220a of terminal 200a is on same straight line, and such arrangement can reduce the actual socket inner space that takies of switch, and more switch can be set.Further alternative,

elastic arm

120a and 220a be extending axially perpendicular to passage 40 all.

Although do not show among the figure, it will be appreciated by those skilled in the art that and below passage 40, in the mode identical with switch 20a-20d the switch identical with switch 20a to be set simultaneously.

The structure of switch 20a and arrangement are so that thereby socket 2 takes full advantage of the superjacent air space that the axial length of passage 40 has effectively utilized passage, and can not affect the utilization in passage 40 axial spaces, the left and right sides, so that in the size that does not change standard socket or keep as far as possible under the prerequisite of compact jack sizes, effectively arrange more switch, make socket realize more function.

Fig. 5 a and Fig. 5 b have shown the exemplary configurations of switch 30a and 30b.Wherein Fig. 5 a has shown the state of

switch

30a and 30b when plug 50 not yet inserts passage 40, and Fig. 5 b has shown that plug 50 inserts the state of passage 40 rear switch 30a and 30b.Below take the contact switch 30a that is positioned at passage left side as example describes, the contact switch 30b that is positioned at the passage right side has the symmetrical structure with switch 30a.

Switch 30a has two

static part

310a, 330a and moving part 320a.Optionally, static part and moving part main body are flat strip substantially.Along left and right directions, set gradually static part 310a left from passage 40 beginnings, moving part 320a and static part 330a,

static part

310a, 330a and moving part 320a extend along the axial direction that is parallel to passage 40 on the whole.The shape of above-mentioned static part and moving part and arrangement all are conducive to the space that switch 30a takes full advantage of passage 40 axial both sides.

Moving part 320a has fixation ends 321a and active distal end 322a, and when plug 50 did not insert passage 40, moving part 320a contact static part 310a can form electrical connection, and this moment, moving part 320a did not contact static part 330a.After plug 50 inserted passage 40, plug 50 promoted active distal end 322a with respect to fixation ends 321a deflection left, makes moving part 320a disengage and contact with static part 330a with static part 310a, formed another road and was electrically connected; And after plug was extracted passage 40, active distal end 322a lost the thrust that plug applies and resets.Thereby realize along with the insertion of plug 50 and extract switch 30a automatically between two circuit, switching.Be to be understood that; switch 30 with two

static part

310a and 330a and a moving part 320a is a kind of exemplary embodiments; it can switch respectively two different circuit; but the needs according to concrete function of socket; include only the switch of a

static part

310a or 330a and a moving part 320a equally within protection scope of the present invention; because although this moment, it can not switch two different circuit; but it has still effectively utilized the socket inner space; thereby increased the switch in the socket so that socket can be realized more function in the situation that do not increase volume; the contact switch (such as 20a-20d) that particularly arranges with the previously described along continuous straight runs of the present invention is when jointly being used in conjunction with, and this advantage is particularly evident.

In order to make the more effective diverter switch 30a of plug 50 energy, at active distal end 322a place extended structure (or parts) 323a that stretches out towards passage 40 can be set further.Thereby after plug 50 inserted passage 40, the terminal 325a that plug 50 promotes extended structure (or parts) 323a was moved to the left.Extended structure (or parts) 323a can be to be to extend formed structure in the bending of active distal end 322a place towards passage 40 as shown in Fig. 5 a and the 5b, also can be that the parts formation that is connected to active distal end 322a place, perhaps an alternate manner are set in addition.The benefit that extension component 323a is set is to make switch more sensitive at least, the effective circuit that connects of diverter switch in the situation that is subject to the thrust that plug applies, and therefore can have more abundant gap between movable member 320a and the passage 40, thereby the structure that dynamic component 310a not can more conveniently be set neatly and movable member 320a is set.

Optionally, moving part 320a forms waveform configuration at its length direction, and waveform configuration is such as crest 326a and trough 327a, and crest 326a protrudes towards static part 310a, and trough 327a protrudes towards static part 330a.Like this, along with the insertion of plug 50 with extract passage 40, crest 326a and trough 327a become respectively moving part 320a and static part 310a and the contacted contact portion of static part 330a.The benefit of waveform configuration is to make switch more sensitive at least, the effective circuit of diverter switch connection in the situation that is subject to the thrust that plug applies.The waveform configuration of the similar sine shown in the figure and cosine is example, and crest and trough also can form other shapes.In addition, as shown in FIG., the more close active distal end 322a of crest 326a that the trough 327a ratio that protrudes towards static part 330a protrudes towards static part 310a, thereby this not only guarantees just to promote active distal end 322a diverter switch 30 when plug 50 insertions put in place rather than just inserted socket, but crest 326a is set also to be fine than the more close active distal end 322a of trough 327a.

When socket of the present invention has contact switch 20a-20d that four along continuous straight runs as shown in Figure 2 arrange and two contact switch 30a that vertically arrange and 30b, just can alternate figures 1a and Fig. 1 b shown in socket and the combination of relay realize that two overlap the automatic switchover of multimedia play equipments.Fig. 6 is two terminals respectively #4, the #5 in the corresponding winding diagrams of each switch of wiring schematic diagram switch 20a-20d of the socket shown in Figure 2 automatic switchover that realizes two cover multimedia play equipments, #2, #7, #8, #1, with #6, #3, A2 in moving part 320a among the switch 30a and the corresponding winding diagram of

movable part

movable part

310b, 330b difference.The same with Fig. 1 a, Fig. 6 signal be the state of plug each switch when not yet inserting socket 2.This moment, socket switch 20a-20d connected, therefore switch #4, the #5 of correspondence link to each other with it in the schematic diagram, #2, #7 link to each other, #8, #1, #6, #3 link to each other, socket switch 30a is connected moving part 320a and is connected with 320b with the static part 310a of being connected and is connected with 310b with 30b, thus in the schematic diagram with it corresponding switch A1, A2 link to each other, B1, B2 link to each other.This sample car inner multimedia playback equipment audio signal by 7., 8. the input, 1., 2. output, vision signal by

The input, 9., 10. output.Although do not show among same Fig. 6, but those skilled in the art are to be understood that, after moving multimedia equipment lead-out terminal (plug) inserted socket, along with the insertion of plug, the switch of switch 20a-20d and 30a and 30b changing as described above, reflection is that switch #4, #5 disconnect in the diagram, #2, #7 disconnect, and #8, #1 disconnect, and #6, #3 disconnect, A2 and A1 disconnect and link to each other with A3, B2 link to each other with the B1 disconnection and with B 3 (identical with Fig. 1 b).Like this audio signal that will play of mobile device directly by 1., 2. output, 10. vision signal directly by exporting.

Explanation those skilled in the art through above-described embodiment understand fully, at least one advantage of socket of the present invention is, it takes full advantage of channel axis with respect to prior art and switch is set the space on the four direction of the left and right sides up and down, it takes full advantage of the space on the passage axial length in both sides up and down, and the while takes full advantage of again the space on the passage radial width in the left and right sides, and the innovative design by switch terminal, so that the up and down organically combination of switch terminal of the switch terminal of both sides and the left and right sides, and the impact that can not cause for the setting of switch each other.So; vertical square along horizontally disposed switch 20a-20d and 2 edges of 4 of above-mentioned layout only is a kind of specific embodiment of the present invention to the switch 30a that arranges and the socket of 30b, as long as the socket that the contact switch of at least one along continuous straight runs setting is set and a contact switch that vertically arranges is set at least on one of passage left side or right side at one of passage upside or downside in receptacle channel is all within the protection range of invention.Such as, minimumly can be only the switch of an along continuous straight runs setting only be set and on one of passage left side or right side a switch that vertically arranges only be set at one of passage upside or downside, again such as, can be simultaneously the contact switch that several vertically arrange be set contact switch and the left and right sides that several along continuous straight runs settings are set, both sides up and down at passage.The quantity of switch can according to the length of passage, need the function of realization and the consideration of cost to increase and decrease fully.

And the structure of the contact switch of along continuous straight runs and each contact switch uniqueness that vertically arranges and arrangement are so that when arranging a plurality of contact switch in the socket of the present invention, the contact switch of each along continuous straight runs has identical structure separately with each contact switch that vertically arranges becomes possibility, the manufacturing cost of contact switch and socket (such as die cost etc.) therefore can greatly reduce.

Fig. 7 is the another kind of embodiment of socket of the present invention, the main difference of the socket 2 that the socket 2 ' among Fig. 7 and Fig. 2 are shown is, it does not comprise contact switch vertically is set in the socket 2, and include only housing 3 ', housing 3 ' has be used to the passage 40 ' that holds plug, and (also can be the below) be provided with the horizontal direction contact switch 20a ' that a plurality of (such as 4) axially be set up in parallel along passage 40-20d ' in the top of passage 40 '.Each contact switch 20a '-20d ' has identical structure.

Contact switch 20a '-20d ' can have the structure similar to contact switch 20a-20d.As shown in Figure 7, contact switch 20a ' comprises terminal 100a ' and terminal 200a ', and terminal 100a ' and terminal 200a ' have free end and stiff end separately; Terminal 100a ' and 200a ' have respectively elastic arm 120a ' and the 220a ' that extends in the passage 40 ' top that holds the plug insertion, elastic arm 120a ' is from passage 40 ' left towards right-hand extension, and its end extends beyond passage 40a ' and forms the free end of terminal 100a '; Elastic arm 220a ' extends towards left from passage 40a ' is right-hand, and its end extends not more than passage 40 ' and forms the free end of terminal 200a '.As shown in the figure, elastic arm 120a ' and 220a ' have lap, in the below of lap elastic arm 220a ' at elastic arm 120a '; Like this, when plug 50 did not insert, elastic arm 120a ' contacted with elastic arm 220a ', and when plug 50 inserted, plug 50 upwards promotes elastic arm 120a ' disengaged itself and elastic arm 220a '.

Equally, similar contact switch 20a, at lap, has protruding 215a ' protruding upward on contact switch 20a ' the Elastic arm 220a ', elastic arm 120a ' can certainly be set makes it have outstanding projection downwards at lap, when plug 50 did not insert, elastic arm 120a ' contacted by the projection on the elastic arm with 220a ' like this.The terminal of contact switch 20a ' can also have other and aforementioned contact switch 20a terminal same structure, so contact switch 20a '-20d ' has all advantages of contact switch 20a-20d.

A kind of exemplary application of socket 2 ' is the audio socket as 3.5mm.This moment, each switch was in closure state when not inserting as the plug 50 of audio jack, and this moment, the output electrical signals indication did not detect plug.After plug 50 inserts, it contacts the terminal 100a ' that upwards promotes each switch-100d ' with each switch, so that each switch is opened, export the signal of telecommunication indication this moment and detect plug 50 insertions, and this moment, 4 terminal 100a were communicated with plug 50, just can realize four electrical connections.In this is used, these 4 terminal 100a '-100d ' are corresponding ground connection successively, L channel, R channel and microphone, plug 50 is along its part that axially arrives from the head corresponding these four terminals of root also corresponding ground connection successively, L channel, R channel and microphone, after plug 50 inserts socket, just realized ground connection like this, the function of stereo output and microphone input.So cooperating with the audio jack of standard, above-mentioned socket realizes simultaneously plug detection and played in stereo function and microphone input function.

So according to the description to contact switch 20a '-20d ', those skilled in the art are to be understood that socket 2 ' has very good inner space utilization ratio equally, can be in the situation that do not increase the socket volume, to realize other more functions.And with respect to the socket of realizing identical function, socket disclosed by the invention is so that jack design is more compact.And its contact switch structure that adopts is simple, low cost of manufacture.
