Specific embodiment
Where completely illustrating the contents of the present invention and feature, a preferred embodiment is provided and cooperates Detailed description of the invention such as
Under.Fig. 1 and Fig. 2 are please referred to, it is by a cylindrical metal conductor 10, a tubular metal conductor 20 along one that the electricity of the present embodiment, which connects device,
Axial L passes through the tubular metal conductor 10, and three o-rings 30 are collectively constituted with an insulating body 40.
It is elongated rod shape and as positive terminal that cylindrical metal conductor 10, which is in the present embodiment, and one end has a plug division
11, outer peripheral surface middle section is equipped with the first groove 12 and fin 13.In the present embodiment, the long axis of cylindrical metal conductor 10 with it is aforementioned
Axial L overlapping.The long axis of other possible embodiments, cylindrical metal conductor 10 can not also be overlapped with aforementioned axial L.
It is hollow tube-shape and as negative terminal that tubular metal conductor 20, which is in the present embodiment, referring to Fig. 2, tubular metal
Conductor 20 is that axially L is coaxially disposed with cylindrical metal conduit 10, and one end is equipped with a contact surface 21.Tubular metal conductor 20
Inner peripheral surface is ladder-like and is equipped with one second groove 22 at change in size, the outer peripheral surface of tubular metal conductor 20 is equipped with one the
Three grooves 23 and a location indentations 24.In other possible embodiments, tubular metal conductor 20 can be connected with conductive sheet work
For power transmission path.
The o-rings such as this 30 are respectively arranged at aforementioned first to third groove 12, and 22,23, and o-ring 30 protrudes from first
To third groove 12,22,23, see Fig. 1.In the present embodiment, the thickness of o-ring 30 axially is greater than first to third
The width of the axially L of groove 12,22,23.For example, 30 thickness of o-ring and first to third recess width difference be situated between
In 0.1~0.4 millimeter (mm), therefore it can ensure that o-ring 30 is located in first to third groove 12,22,23.Other can
Can embodiment, such as variation first is to the concave shape of third groove, as long as o-ring 30 can be made substantially to fill up first to the
Three grooves 12,22,23 can position o-ring 30.
O-ring 30 can be made of silica gel or fluorubber elastomeric material, to provide enough heat resistances.This
Outside, the interior perimeter of o-ring can make the contraction of o-ring 30 itself less than first to the perimeter of 12,22,23 bottom of third groove
Power can be used to that o-ring 30 is helped effectively to be located in first in third groove 12,22,23.
Insulating body 40 is middle section and the tubular metal conductor 30 that tubulose metallic conductor 20 is coated made by plastics
Inner peripheral surface and outer peripheral surface, while plug division 11 and contact surface 21 being made to be exposed to the same side of insulating body 40.Therefore, the present embodiment
Electric connector can be connected with another connector (figure be not painted).
It is noted that o-ring and the quantity of groove are not limited with three of previous embodiment, can optionally subtract
Less it is one or increases to four or more, closes the gas leak path of electrical connector interior.
The production method of the present embodiment power connector is as shown in Figure 3.Step S1 is first carried out, prepares tubular metal conductor
10, with cylindrical metal conductor 20, are arranged the first groove 12, the second groove 22 and third groove 23, and by 20 edge of cylindrical metal conductor
Axial direction L pass through tubular metal conductor 20 inside.Then step S2 is executed, it is recessed to third that o-ring 30 is assembled in aforementioned first
Slot 12,22,23, and make the protrusion of o-ring 30 first to third groove 12,22,23.Then, execution step S3 be embedded to and is penetrated
It forms, that is, tubular metal conductor 10, cylindrical metal conductor 20 and o-ring 30 is located in a mold, o-ring 30 out
Vertical axial L can be set into, molten plastic is irrigated in a manner of parallel axial direction L, and then o-ring 30 is completely covered, it
Plastics cool and solidify to form insulating body 40 afterwards.Finally enter manufacture and assembling that step S4 completes the present embodiment electric connector.
During being embedded to ejection formation, the plastics that there is o-ring 30 enough heat resistances can endure melting, and
O-ring 30 is being firmly fixed on first in third groove 12,22,23, avoiding generating position during plastics flow
It moves.Since the protrusion first of o-ring 30 is to third groove 12,22,23, because plastics will cover o-ring 30, simultaneously towards first to
Compress o-ring 30 in the direction of 12,22,23 bottom of third groove.Therefore, after plastics cooled and solidified, electric connector will be completed
Fabrication schedule, step is relatively easy, and between o-ring 30 and insulating body 40 can certain confining gas leakage paths,
Achieve the effect that air-tight water-proof.It is led in addition, insulating body 40 can be strengthened by fin 13 with location indentations 24 with tubular metal
Bonding strength between body 10, cylindrical metal conductor 20.
Finally, must illustrate again, the present invention is only for example in the composition element disclosed in previous embodiment
Range that is bright, being not intended to limit the invention, such as other easy full of beard and structure change, or the substitution with other equivalence elements
Variation, the claim that also should be of the invention are covered.
