Embodiment 1
Shell binding face of the boss 22 towards a side surface of shell 1, with bottom base with reference to Fig. 2, on top base ontology34 are mutually flush, and may make the fixation of top base more reliable.
The ring flange 12 of 1 circumference of shell and shell binding face 34 are equipped with mutual corresponding mounting hole 13/36, mounting hole itBetween be connected and fixed by lock-screw 4；It is mutually right that the lock-screw is equipped with the mounting hole inner sidewall on shell binding faceThe anti-rotation face 35/44 answered.It may make the fixation between top base and bottom base more reliable, it is easy to disassemble.
Refering to what is shown in Fig. 1, top base connecting pin outer diameter is greater than inserted terminal outer diameter, the mounting hole 36 on shell binding face 34 isTapped through hole, as shown in connection with fig. 4, the thread root of lock-screw 4 are arranged with sealing ring 5, and the tail end of lock-screw is equipped with nut8, elastic slice 7 is arranged on the lock-screw between nut 8 and mounting hole 36.The lock-screw that is set as of elastic slice provides preloadPower, the setting of sealing ring ensure that the sealing of top base Yu bottom base connecting portion.
Such as Fig. 1, the inserted terminal periphery of bottom base is arranged with the second sealing ring 6, and the circumference of the second sealing ring is embedded in top baseIn connecting pin, the sealing performance of screw installation site is further improved.
In connector, described first patch end and second patch end match between corresponding connector accommodating chamber for gapIt closes, guarantees to patch and hold certain elasticity, to ensure electrical connection properties.
With reference to Fig. 3, the bending part of connector interconnecting piece is bent into V-type or U-shaped, can more effectively prevent the glue poured into from flowing intoIn the connector accommodating chamber of bottom base.
Embodiment 2
In the present embodiment, converter be 15 core converters, top base ontology be it is trapezoidal, top base intrinsic 15 patchPart accommodating chamber is arranged at 5*3, and the center of two rows and the center of an intermediate row are in the horizontal direction, respectively relatively onThe center of base body deviates identical distance towards different directions.
The linkage section of connector i.e. first patches end and second patches the electric connection structure between holding, can be by the first grafting memberThe connecting pin of part (provide first and patch end), the company between the first plug connector elements and the second plug connector elements (provide second and patch end)The connecting pin of fitting and the second plug connector elements composition.
As shown in Figure 1 to Figure 3, top base ontology 2 is equipped with connector accommodating chamber 23, and bottom base 3 is equipped with connector accommodating chamber33, the edge rolling end 91 on the connector I 9 of two rows and the edge rolling end 101 on the connector II 10 of an intermediate row can correspond to slottingEnter in accommodating chamber 23；Inserted sheet end 104 can correspond in insertion accommodating chamber 33 on inserted sheet end 94 and connector II 10 on connector I 9.It connectsConnecting pin 102 on 92 and connector II 10 is connected on plug-in unit I 9 to be located on bottom base 3 in encapsulating chamber 32.Connector I 9 and connectorII 10 are packed into after bottom base 3, gluing sealing are carried out in encapsulating chamber 33, the fully wrapped around connecting pin 92/102 of colloid, colloid is solidThe unnecessary clearance effectively between isolation top base 2 and bottom base 3 is played after change, guarantees product hermeticity.
Since adapter both ends are with socket interfix, i.e., with socket interworking, encapsulating is close for top base ontology 2 and bottom base 3Colloid must not flow to top base 2 and bottom base 3 to slotting region when envelope.And connector I 9 and connector II 10 are accommodated in connectorIt is assembled for gap in chamber 23/33, it is final to flow since the mobility of colloid necessarily causes glue to flow along gap when sealant pouring and sealingIt is used to slotting regional effect product.To guarantee product normal use and improving product degree of protection, the present embodiment will patchedPart I 9 and connector II 10 are packed into before bottom base 3, on connector I 9 to slotting region except, and keep increasing at effective distanceFlex area 93, on connector II 10 to except slotting region and keep at effective distance increase flex area 103, flex area 93,103 smear silica gel, and after connector I 9 and connector II 10 are packed into bottom base 3, flex area 93,103 smeared silica gel can be filled inIn encapsulating chamber 33, plays glue when preventing encapsulating and flow to slotting region.
As shown in Figures 1 to 4, shell 1 is equipped with circular hole mounting hole 13, and top base is equipped with circular hole mounting hole 36, and is equipped with anti-Turn face 35, O-ring seal snare enters the thread root 45 of lock-screw 4, and lock-screw main body 43 passes through circular hole 13, circular hole 36 fillsEntering bottom base 3, setting up defences in lock-screw anti-rotation face 44 and bottom base 3 turns face 35 and matches, and nut 42 is pressed on shell 1, from3 reverse side of bottom base is packed into elastic slice 7 and tightens nut 8.
Mounting hole is corresponded to since 5 outer diameter of O-ring seal is less than in bottom base 3, and O-ring seal 5 is in compression after lockingState can play the role of interfacial seal.
The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the artFor art personnel, without deviating from the technical principle of the utility model, several improvement and deformations can also be made, these changeIt also should be regarded as the protection scope of the utility model into deformation.
