Fig. 1 shows the exploded perspective view according to the waterproof electrical connector of an embodiment of the utility model.
Fig. 2 shows the generalized section according to the waterproof electrical connector of an embodiment of the utility model.
Embodiment
Be described in further detail below in conjunction with the utility model of embodiment, but execution mode of the present utility model is not limited thereto.
Fig. 1 shows the exploded perspective view according to the waterproof electrical connector of an embodiment of the utility model.A kind of waterproof electrical connector as shown in Figure 1, comprise housing 101, the connection end face 102 of described housing 101 is provided with the seal 103 for waterproof, described housing 101 is provided with at least two stepped holes 104, be used for installing the screw 105 with step in this stepped hole 104, described screw 105 is provided with sealing ring 106, and screw 105 is provided with the groove 107 that holds sealing circle 106.Also be provided with back-up ring 108 on the described screw 105, this back-up ring 108 is arranged on step 109 places of screw 105.
The connection end face 102 of described housing 101 roughly can be rectangle, and corresponding described seal 103 also is rectangle.The connection end face 102 of this housing 101 is provided with the groove 110 that holds described seal 103, and this groove 110 can be U-shaped groove.
Described seal 103 integral body are sucked type, and seal 103 openings are trumpet type, are used for being connected with panel; Described seal 103 bottoms are smooth rectangle, are used for being connected with housing 101 grooves 110.
During use, only seal 103 end faces need be contacted with panel, rotary screw 105 is connected with socket other end nut then.
Fig. 2 shows the generalized section according to the waterproof electrical connector of an embodiment of the utility model.A kind of waterproof electrical connector as shown in Figure 2, total is made up of seal 203, housing 201, Water-proof screw assembly; Described seal 203 integral body are the waist type, and opening is trumpet type, and the bottom is smooth rectangle, and rectangular bottom surface is connected with the U-shaped groove 210 of housing, and the loudspeaker opening is connected with panel; Described housing 201 can adopt intensity moderate, the plastics that plasticity is good, and establish two stepped holes 204 in both sides, be used for the installation of Water-proof screw assembly; Described Water-proof screw assembly is by packing ring 208,0 RunddichtringOs 206, and Water-proof screw 205 is formed.Water-proof screw 205 is radially fluted, is used for placing 0 RunddichtringO 206.
The Water-proof screw assembly is installed in two stepped holes 204 of housing 201, uncovered RunddichtringO (seal 203) is installed in the U-shaped groove 210 of housing 201.Be connected with other end screwed hole on being fixed on panel by Water-proof screw 205, be close to panel after making waist RunddichtringO (seal 203) extruding like this, form negative-pressure sealing, simultaneously, the Water-proof screw assembly seals the stepped hole place by 0 type circle, 206 extruding housing steps.
The benefit of rectangle end face negative-pressure adsorption waterproof construction is: increased the end face seal area, formed negative pressure, the classification of waterproof height has solved the bad problem of vibration environment lower panel waterproof effect simultaneously.
During connection, only need be close to panel to water proof ring (seal 203) end face, tighten Water-proof screw 205 then, by the extruding of water proof ring (seal 203) with panel, the extruding of water proof ring (seal 203) and housing 201 grooves 210, rubber ring on the Water-proof screw 205 (0 type circle 206) forms sealing with the step extruding.During dismounting, only need loosening Water-proof screw 205.Advantages such as therefore this rectangle end face water-proof connector has simple in structure, operating aspect, connection is reliable and stable, coupling mechanism force is moderate.
