Description
Technical field
The present invention relates to conductive connecting device, particularly relate to a kind of electric connector.
Background technology
Existing electric connector jack contact form mainly contains open pore, line spring hole, string of a hat hole with the forms such as spring hole of coming of age, but the jack of quovis modo all relies on radial elastic pressure to realize contact pin and the direct reliable contacts of jack when contacting with contact pin.And the reliable contacts of pin hole will be ensured, need that axially there is certain contact length, which adds the axial dimension of electric connector, greatly limit its applicable situation.
The Chinese utility model patent that Authorization Notice No. is CN203521699U, authorized announcement date is 2014.4.2 discloses a kind of electric connection structure reducing contact resistance, this electric connection structure comprises pole and contact, pole comprises substrate and conductive contact, the axial end of substrate is provided with mounting groove, be provided with the canted coil spring that can protrude from substrate surface in mounting groove, external plane is pressed against on the canted coil spring in the mounting groove of substrate and realizes the electrical connection with pedestal.This electric connection structure by the axial end of pedestal namely conduct electricity interface realize conduction connect, reduce axial contact length, and then reduce the volume of electric connector.But the substrate of this electric connection structure is annular U-type groove for installing the mounting groove of canted coil spring, canted coil spring is easy to move axially in U-type groove, the stability that impact conduction connects, when external plane is separated with substrate, canted coil spring also skids off from the aperture position of mounting groove easily, connection is conducted electricity in impact normally, and reliability during use, fail safe are poor.
Summary of the invention
The object of the present invention is to provide the canted coil spring on a kind of conductive contact that the electric connector of axial displacement can not occur.
In order to solve the problems of the technologies described above, electric connector of the present invention adopts following technical scheme: a kind of electric connector, comprise contact, described contact comprises conductive contact, described conductive contact comprises body, body is provided with conduction interface, conduction interface is provided with axes normal in the annular mounting groove for installing conduction spring coil of conduction interface, described annular mounting groove has for supplying conduction spring coil to load from axial direction, diameter is greater than the notch of conduction spring coil internal diameter in its natural state, the side cell wall near its axis of described annular mounting groove is inner side cell wall, the diameter at the notch position place of inner side cell wall is greater than the diameter of bottom land position.
Inner side cell wall is the taper seat reduced gradually from notch to groover rot diameter.
Described contact has two or more and is set up in parallel.
The conduction interface of electric connector conductive contact of the present invention is provided with annular mounting groove, and this annular mounting groove has the opening loaded from axial direction for conduction spring coil, the diameter at the notch position place of inner side cell wall is greater than the diameter of bottom land position and the diameter of its notch position is greater than conduction spring coil internal diameter in its natural state.Such conduction spring coil could load in mounting groove after only having radial spreading, and loading radial contraction after in mounting groove and kept off in mounting groove by the wall of the notch position of inner side cell wall, conduction spring coil is avoided to move axially in mounting groove or depart from mounting groove, not only easy for installation, simultaneously also very reliable and stable in conduction connection procedure.
Further, inner side cell wall is that taper seat greatly reduces difficulty of processing, reduces manufacturing cost.
Further, contact comprises two or more and is set up in parallel, and can transmit the different signal of telecommunication of multichannel in use by an electric connector, easy to use.

Embodiment
The embodiment one of electric connector of the present invention: as Figure 1-3, the contact comprising electric connector housing 3 and be located in housing, conduction 4 to stretch in electric connector housing 3 from incoming line and conducts electricity with contact and is connected, in order to realize multi-channel electric signal transmission, contact can have two or more and be set up in parallel on the direction perpendicular to grafting direction, the structure of contact as shown in Figure 4, comprise conductive contact 1 and be arranged on the conduction spring coil 2 on conductive contact 1, the structure of conductive contact 1 as shown in Figure 5, comprise the body that left and right extends, body is provided with conduction interface, i.e. left side, conduction interface is provided with axes normal in the annular mounting groove 10 of conduction interface, annular mounting groove has for conducting electricity spring coil 2 from axial direction namely from the opening that left direction loads, for convenience of description, the side cell wall near its axis of definition annular mounting groove 10 is inner side cell wall, the diameter at the notch position place of inner side cell wall is greater than the diameter of bottom land position, and the diameter of the notch position of inner side cell wall is greater than conduction spring coil 2 internal diameter in its natural state.
When installing conduction spring coil 2 on conductive contact 1, the conduction first radial spreading of spring coil 2 also makes its internal diameter be greater than the diameter at the notch position place of inner side cell wall, conduction spring coil 2 from the opening of annular mounting groove 10 to enter in annular mounting groove 10 and under natural resiliency effect automatic radial contraction, now, the internal diameter of conduction spring coil 2 diminishes and is less than the diameter at the notch position place of inner side cell wall, such conduction spring coil, just by cell wall institute's block at cell wall notch position place, inner side and stretching and can not moving axially in annular mounting groove 10, more can not come off automatically from annular mounting groove; During use, the conduction interface that adaptive conductive contact piece 5 is resisted against contact realizes stable conductive contact by pressing conduction spring coil 2, and conducting process is reliable and stable.
In the present embodiment, inner side cell wall is the taper seat reduced gradually from notch to groover rot diameter, and structure is simple, and easy to process, manufacturing cost is lower, and in other embodiments, inner side cell wall also can be towards the cambered surface of axis direction indent.
In the present embodiment, conduction spring coil is canted coil spring, and as shown in Figure 6, it adopts elastomeric wire coiling to form, and adopts welding or other is with appropriate process electric connector together with, formation circle assembling structure at two ends wiry interface.In winding process each circle wire and whole canted coil spring central diameter axis shape at a certain angle, this angle can ensure that canted coil spring compresses in axially loaded situation and close up, thus form certain elastic holding force, ensure that contact end face forms reliable electric contact.Certainly, in other embodiments, the spring coil that conducts electricity also can adopt common fingertip spring.
Electric connector of the present invention realizes axial conduction by the conduction spring coil be located on contact end face and connects, can allow, between plug and socket, there is larger radial missing in use, reduce grafting difficulty, reduce axial length and the volume of electric connector, easy to use; Power spring can not move axially relative to conductive contact or depart from from conductive contact, uses reliable.
