Abstract
The utility model discloses an injection plug-in connector comprising a common sound channel segment with a ring groove provided with a clamp spring ring matched with the ring groove and a crowning surface in the middle part of the clamp spring ring. The ring groove on the common sound channel segment can match with the clamp spring ring with a crowing surface, the contact insertion-and-withdraw force of the plug-in connector is increased and the plug-in connector is more reliable and firm after being inserted into the connector and at the same time the friction noise is greatly reduced. The clamp spring ring can increase the resistance, therefore the plug-in connector can be slowly inserted into the jack of the connection chair to prevent generating instant large level when the audio main signal contacts with an amplifier and to reduce the static noise.
Description
Technical field
The utility model relates to a kind of connector, especially relates to a kind of injection moulding formula plug-in connector.
Background technology
The main effect of injection moulding formula plug-in connector is by the Connection Block that is mated message to be passed to loud speaker via the message lead, and such as commercially available earphone etc., therefore, injection moulding formula plug-in connector connects the convenience that has operation and use in the transmission of message.
Commercially available injection moulding formula plug-in connector mostly is the national standard part at present, mainly contain two kinds: a kind of is the monophony plug-in connector with main sound channel section and public sound channel section, and another kind is the stereo plug-in connector with L channel section, R channel section and public sound channel section.Plug-in connector Connection Block 1 common and as shown in Figure 8 is used, directly insert plug-in connector in the jack 12 that is arranged on the bearing 11 during use, under the effect of spring leaf 13, contacting between plug-in connector and the jack 12 is reliable and stable, and audio signal is exported by the loud speaker that is connected with plug-in connector by the contact of conductive base pin 14 and plug-in connector, but this plug-in connector exists significantly not enough: because it mainly relies on spring leaf to fix plug-in connector, and the active force of spring leaf is less, make and have loosening phenomenon between plug-in connector and the jack, it is not firm to peg graft, thus the audio signal quality of influence output; Can produce certain vibration during speaker operation, this vibration also can cause and is connected looseningly between plug-in connector and the jack, influences the normal transmission of audio signal; When plug-in connector inserts Connection Block, because the process of pegging graft produces friction than comparatively fast causing between plug-in connector and jack 12 inwalls, this friction will produce bigger friction noise after amplifying through amplifier; When plug-in connector inserts Connection Block, the public sound channel section of plug-in connector and the grounding wafer in the conductive base pin 14 electrically connect, and make public sound channel section ground connection, at this moment, may produce big level of moment when audio signal contacts with amplifier, thereby cause electrostatic noise.
Summary of the invention
Technical problem to be solved in the utility model provides firm, low friction noise of a kind of grafting and low electrostatic noise, can guarantee the injection moulding formula plug-in connector of the audio signal of outputting high quality.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of injection moulding formula plug-in connector, this plug-in connector comprises public sound channel section, described public sound channel section is provided with cannelure, described cannelure is provided with the jump ring circle that is mated, and the mid portion of described jump ring circle is provided with the face of arching upward.
The axial length of described jump ring circle is equal to or less than the axial length of described cannelure.
The cross-sectional diameter at the two ends of described jump ring circle is equal to or less than the cross-sectional diameter of described public sound channel section.
Described jump ring circle is provided with an axial cut-outs.
Axially be provided with a plurality of microscler through holes on the described face that arches upward, the length of described microscler through hole is equal to or less than the axial length of the described face that arches upward.
Described microscler through hole evenly is arranged on the described face that arches upward.
The width of described microscler through hole is 1:3～1:6 with the length of described microscler through hole ratio.
Compared with prior art, advantage of the present utility model is to be arranged on the use that cooperatively interacts of cannelure and the jump ring circle with the face of arching upward on the public sound channel section, increased the contact engaging and separating force of this plug-in connector, make this plug-in connector insert behind the connector more reliable firmly, greatly reduce friction noise simultaneously; The setting of jump ring circle has increased resistance, makes this plug-in connector insert comparatively slowly in the jack of Connection Block, and the big level of moment that has produced when having avoided the audio frequency main signal to contact with amplifier has reduced electrostatic noise.

Embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
Embodiment one: as shown in Figure 1, Figure 2, Figure 3 and Figure 4, a kind of injection moulding formula plug-in connector, this plug-in connector 2 comprises public sound channel section 21 and main sound channel section 22.Public sound channel section 21 is provided with cannelure 23, the position of the end 121 of the jack 12 on these cannelure 23 residing positions and the outside Connection Block 1 is corresponding, be movably set with the jump ring circle 24 that is mated on the cannelure 23, the mid portion of jump ring circle 24 is provided with the face of arching upward 25, the axial length of jump ring circle 24 is equal to or slightly less than the axial length of cannelure 23, the cross-sectional diameter at the two ends of jump ring circle 24 is equal to or less than the cross-sectional diameter of public sound channel section 21, like this when this plug-in connector 2 inserts outside Connection Block 1, the face that arches upward 25 of jump ring circle 24 make be connected between this plug-in connector 2 and the jack 12 more fastening.Jump ring circle 24 is provided with an axial cut-outs 26, jump ring circle 24 is inserted in cannelure 23 or when cannelure 23 takes off, this axial cut-outs 26 can make the cross section of spring coil 24 enlarge under external force, makes when using jump ring circle 24 more convenient, more flexible.
