Connection.D+ stitch 19 and D- stitch 20 are used for compatibility USB2.0 USB differential signals, can by D+ stitch 19 and D- stitch 20
Transmit signal, such as audio signal or control signal.The pad of two stitch connects with the D+ lines in earphone cord and D- lines respectively
Connect.VBUS stitch 15 is used to power to earphone.For example, the power end VBUS1 and coding unit of VBUS stitch 15 and decoding unit
Power end VBUS2 connections, to be powered to decoding unit U1 and coding unit U2, it is ensured that their normal work.CC stitch 21
For recognizing mode of operation, such as CC is used to detect positive anti-plug, differentiation principal and subordinate, configuration voltage of VBUS.
The CC stitch 21 of Type-C connectors is connected to pull down resistor 18.For example CC stitch 21 passes through pull down resistor 18 and ground wire
Conducting.For example, CC stitch 21 is connected by pull down resistor 18 with the pcb board of earphone.So, earphone is by detecting the drop-down
The size of resistance 18 judges that the Type-C plugs 11 are digital signal communication pattern or analog signal communication pattern, and according to
The communication pattern of the Type-C plugs 11 currently connected, the signal of model identical is transmitted by corresponding stitch.If specifically,
Type-C plugs 11 are analog signal communication patterns, and the electronic equipment of connection will transmit simulation by D+ stitch 19, D- stitch 20
Signal.
Connector body includes the plug 11 and connecting portion 12 linked together.For example, when in use by connector body
Insert in female seat, to carry out the transmission of electric power or signal.
The respective contact 16 of above-mentioned five stitch is located in plug 11, and the respective pad of above-mentioned five stitch is located at
Connecting portion 12.For example, stitch is by same sheet material is stamped etc., mode is molded.One end of stitch is contact 16, and the other end is pad.
The trend of stitch can be configured according to actual needs.Contact 16 is located in plug 11, and at least a portion of plug 11
Exposed A faces or B faces in plug 11.A faces or the surface in the width direction that B faces are plug 11, two surfaces are used to set
Contact 16 is put, to be linked together with female seat.A faces are oppositely arranged with B faces.
TYPE-C connectors of the present utility model, pin package is by ground pin 14, D+ stitch 19, D- stitch 20, VBUS
Stitch 15 and CC stitch 21 are constituted, and can realize the functions such as the transmission, charging, positive anti-plug of the control signal, audio signal of earphone.
In addition, the connector need not set the stitch beyond above-mentioned stitch, and it is simple in construction, it is easily manufactured, save material,
Manufacturing cost is low.
In addition, above-mentioned five stitch are directly connected with the lead 17 of earphone cord, without setting pcb board, further simplify
The structure of connector, reduces difficulty of processing, manufacturing cost is low.
Further, since pcb board is not provided with, therefore maintenance is convenient.
Fig. 1 is the front view of the connector according to one embodiment of the present utility model.Fig. 2 is according to of the present utility model
The top view of the connector of one embodiment.Fig. 3 is the upward view of the connector according to one embodiment of the present utility model.
As Figure 1-3, in this example embodiment, the contact 16 of five stitch is located at the same face of connector, such as A respectively
Face.Stitch extends to connecting portion 12.Four are located at the same side in five pads, and another pad is located at opposite side.For example, ground connection
Stitch pad 141, VBUS stitch pad 151, D+ stitch pad 191 and D- stitch pad 201 are located at the same side, CC stitch pads
211 are located at opposite side.In this way, it is easy to lead 17 to be welded on pad.For example, by ear by way of soldering is welded
The corresponding lead 17 of machine wire is respectively together with the pad solder of above-mentioned five stitch.
Certainly, those skilled in the art can set contact 16 and the position of pad according to actual needs.
Optionally, for example, pull down resistor 18 can be arranged in connector body, now, CC stitch pad 211 leads to
Cross wire pull down resistor 18 is connected with ground wire.For example, pull down resistor 18 can also be arranged on the PCB controlled in earphone
And connected with PCB ground wire, CC stitch pad 211 is directly gone here and there by the lead 17 of earphone cord with pull down resistor 18
Connection.
In one example, as shown in figure 5, the resistance value of pull down resistor 18 is 5.1k Ω.Earphone is by detecting the drop-down
The size of resistance 18 judges that the Type-C connectors are digital signal communication pattern or analog signal communication pattern, Ran Houzai
Matched, to realize data transfer.
Certainly, those skilled in the art can select the resistance of pull down resistor 18 according to actual needs.
In one example, TYPE-C connectors also include the shielding case 13 being set in outside plug 11.The shielding case 13 with
Ground wire is connected.In this way, connector can effectively shield the interference of external signal, so that number signal transmission is more accurate
Really.For example, shielding case 13 is made by materials such as copper alloy, aluminium alloy, ferroalloy, stainless steels.
In one example, TYPE-C connectors also include being embedded the supporting part in plug 11.Supporting part is used to strengthen
The structural strength of connector, to avoid plug 11 from being bent during plugging and unplugging repeatedly.Supporting part insulate with stitch, to keep away
Exempt to interfere signal transmission.Optionally, supporting part is sheet, and it is made by metal, for example, supporting part is support
Plate 22, supporting plate 22 can select the materials such as copper alloy, aluminium alloy, stainless steel, carbon steel.For example, using modes such as punching press, injections
Form supporting plate 22.
In one example, supporting part is sheet, and parallel with the A faces or B faces of plug 11.The structure of sheet has
Bigger stress surface.In this way, the intensity of connector body can effectively be strengthened.
In one example, connector body is injection molding, and pad is embedded in connecting portion 12.The stitch in injection moulding process
Fixed by plastics or plastic cement.In this way, moulding can provide protection for pad, prevent from plugging and unplugging in connector
During stitch come off.For example, connector body can be by flexible glue injection molding.Flexible glue is to be formed with plastics by being molded, often
The lower feel of temperature is softer, and many people are called " flexible glue ", but are not required to by vulcanizing treatment.Flexible glue has temperature-resistance characteristic, weatherability, electricity
The excellent properties such as gas insulating properties, physiological inertia and low surface tension and low-surface-energy.Therefore, by the connection of flexible glue injection molding
Device body, can effectively protect the junction of pad and lead 17, it is to avoid bend.
According to another embodiment of the present utility model, there is provided a kind of earphone.The earphone is provided including the utility model
TYPE-C connectors.
Although some specific embodiments of the present utility model are described in detail by example, this area
It is to be understood by the skilled artisans that example above is merely to illustrate, rather than in order to limit scope of the present utility model.This
Field it is to be understood by the skilled artisans that can be in the case where not departing from scope and spirit of the present utility model, to above example
