Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention will be further described.
The female end 100 of Small Distance connector comprises: shell 110, long contact is long jack 121, five short circuit contact element is short jack 122, insulation keeper 130, screw connector 140, jube 150 and O RunddichtringO 160.
The male end 200 of Small Distance connector comprises: shell 210, long contact is long contact pin 221, five short circuit contact element is short contact pin 222, insulation keeper 230, bolt connection piece 240 and jube 250.
All contacts have three hangnails 121-1,122-1,221-1,222-1.Hangnail contact is fixed in insulation keeper 130,230.Hangnail is interfered with insulation keeper, avoids the withdraw of the needle.The quantity of hangnail can arrange one or more according to the size of connector plugging power.All contacts have weldering cup 121-2,122-2,221-2,222-2, for welding wire.
The front end of jack has elastic spring 121-3,122-3, has contact end face 221-3,222-3 with the front end of contact pin.Elastic spring with contact end contact, turning circuit.Long jack and long contact pin have step surface 121-1,221-4 and jube 150,250 end face is fitted, and realizes the location of jube.
Insulation keeper 130,230 has installing hole 131,231, and contact is just arranged in installing hole.Insulation keeper 130,230 also has groove 132,232, after connector completes shell injection moulding, fills plastic cement and carry out waterproof in groove 132,232.The insulation keeper 130 of female end also has connection location notch 133, plays positioning action when being connected with Male end connector.
Screw connector 140 has internal thread 141, and bolt connection piece 240 has external screw thread 241.When connector docks, screw-threaded engagement, ensures the fastness that connector connects.
Jube 150,250 has the accommodation hole 151,251 of long contact 121,221, also has the groove 152,252 corresponding with short circuit contact element 122,222 quantity and position, by mutually isolated for each contact.
As Figure 16 and Figure 17, installing hole 231 is countersunk head formula stepped hole, therefore has gap between the tail end of installing hole 231 and short jack 222.Certainly, after long jack 221 loads installing hole, this position also has gap.After connector completes shell injection moulding, the gap-fill plastic cement between installing hole and jack carries out waterproof.
Jube 250 is enclosed within long contact pin 221, long contact pin 221 is being inserted the installing hole 231 being positioned at center, until the rear end face of jube 250 end face laminating insulation keeper 230.As shown in figure 18, the length of jube 250 is greater than the length that short contact pin 222 afterbody exposes insulation keeper 230, long contact pin 221 and each short contact pin 222 is fully kept apart.Add minimum range and creepage distance between Small Distance bonder terminal, be improved when the electric property of connector is lifted at diameter configuration size constancy.Jack, the insulating mount of Male end connector are similar to terminative connector to mounting means with the structure of jube, at this just no longer repeated description.
After completing the installation of contact, be enclosed within by connector 140,240 on insulation keeper 130,230, then just injection moulding, forms shell in the outside of assembly, plays a protective effect to the inside of connector.
The sealing ring 160 of Small Distance connector male end, is arranged on the connecting end surface of insulation keeper 130.
The assembly method of Small Distance connector male end is as follows:
Steps A. short contact pin is loaded in the corresponding installing hole of insulation keeper.
Jube is enclosed within the tail end of long contact pin by step B., then is loaded by long contact pin in the corresponding installing hole of insulation keeper, and the end face of jube is fitted with the end face of insulation keeper.
Bolt connection piece is enclosed within insulation keeper by step C..
The parts assembled are carried out injection moulding by step D., form shell.
Step e. fill plastic cement at gap location and seal.
The assembly method of Small Distance connector female end is identical with male end, just a last increase step: connecting end surface sealing ring being contained in insulation keeper.
