Detailed description of the invention

Below in conjunction with accompanying drawing embodiment, this utility model is described in further detail.

It is this utility model preferred embodiment one as Figure 1-3.

As shown in Figures 2 and 3, in the waterproof combo socket in the present embodiment includes that panel 1, sealing gasket 2, housing 3 insulate Core 4, push button part 5, shell fragment 6, conductor terminal 7.In the present embodiment one, your socket includes three conductor terminals 7.

Conductor terminal 7 is for long tubular and is axially set in insulation inner core 4.Conductor terminal 7 is by wire upper terminal 71 and leads Line lower terminal 72 is combined into, and wire upper terminal 71 is the cylinder of hollow, is set in advance in insulation inner core 4 internal；Wire lower end The connection end that son 72 is connected with wire upper terminal 71 can be plugged in the vestibule of wire upper terminal 71.Wire lower terminal 72 upper End is disposed with double wedge 721 radially, is also coated with adhesive in the gap between double wedge 721.

Insulation inner core 4 in be provided with three cylindrical vias 42 vertically, place for conductor terminal, the upper end of guide hole on lead Hole 421, diameter, less than the diameter of wire upper terminal 71, inserts for plug wires terminal.Meanwhile, upper guide hole 421 diameter is less than Wire upper terminal 71 is such that it is able to block wire upper terminal 71 and do not come off from upper end.Outside lower guide hole 422 diameter is with conductor terminal 7 Footpath is identical, is used for conductor terminal 7 of planting.

Bottom end cover 41 is shaped on the outer peripheral face of insulation inner core 4 lower end.For being connected with shell 3.

The outer peripheral face of insulation inner core 4 is step convex shape with the inner side of described bottom end cover 41.

The latching device that constitutes of part 5 is turned round between insulation inner core 4 and shell 3, the upper end 61 of shell fragment 6 by shell fragment 6 and pushing away Being arranged on insulation inner core 4, lower end has the push pedal portion 63 of outwards tilting, and dead bolt 62 projection of shell fragment takes shape in the middle part of shell fragment 6 And be positioned in insulation inner core 4；Dead bolt 62 is locked with the lockhole of CANNON plug 9 and is coordinated, can by CANNON plug 9 with combo socket even Connect closely.Push button part 5 lower end has extended internally a push arm 52, and this push arm 52 offsets with push pedal portion 63, and can promote push pedal portion 63 Elastic deformation, operating side 51 extending panel 1 of push button part downwards.

As shown in figures 1 and 3, panel 1 has central through hole.

Sealing gasket 2 is axially hollow and is located at the lower section of panel 1.Sealing gasket 2 stretches out and is provided with a company that can bend Meeting portion 21, the end of this connecting portion 21 is formed with one can be with the capping 22 of panel 1 central through hole adaptation.

Housing 3 is positioned at the lower section of sealing gasket 2, and axially hollow formation one supplies inner chamber the upper end radial direction of insulation inner core 4 setting Stretch out and form the installation portion 31 of one and panel 1 assembly connection.

It is internal that insulation inner core 4 is positioned at housing 3, and interior the fixing with housing 3 of central through hole being located at panel 1 is connected.

Seeing Fig. 2, the lower surface 32 of described housing 3 forms groove 321, and this groove 321 is provided with a sealing ring 8, lower end After lid 41 assembles with housing 3, sealing ring 8 is between the upper surface 411 and groove 321 of bottom end cover 41.The upper surface of sealing ring 8 Being in close contact with the groove 321 on housing 3 lower surface 32, the lower surface of sealing ring 8 and the lower surface 411 of bottom end cover 41 closely connect Touching, thus rainwater cannot enter inside combo socket from the installation gap that bottom end cover 41 and housing 3 fit together, closely and Improve the water resistance of combo socket.

Embodiment two, as shown in Figure 4, embodiment two is with the difference of embodiment one: the conductor terminal of embodiment 27 Number is five.
