Embodiment
By describing technology contents of the present utility model, structural feature in detail, realized purpose and effect, give explanation below in conjunction with execution mode and conjunction with figs. are detailed.
See also Fig. 1 and Fig. 2, the electric power connector 100 of the utility model tool shield shell comprises a plastic casing 20, plastic casing 20 inner fixing plurality of terminals 40, the outside shield shell that coats, this shield shell is made up of first shield shell 60 that is coated on plastic casing 20 outsides and the secondary shielding housing 80 that is coated on first shield shell, 60 outsides.
See also Fig. 3, the end face of plastic casing 20 is offered a pair of stopper slot 21, and this is to stopper slot 21 separation end face both sides and longitudinal extensions, and its front end seals, and the rear end also is in communication with the outside.The front end face level of plastic casing 20 is extended a hyoplastron 22 and a pair of base plate 24 that is positioned at hyoplastron 22 belows and is set up in parallel forward.Described hyoplastron 22 is vertically offered plurality of terminals groove 23, in order to corresponding build-in terminal 40.Form a location guide groove 26 between described two base plates 24, locating channel 26 back-end closures, front end is in communication with the outside; 22 of the hyoplastrons of described base plate 24 and plastic casing 20 also form first slot 27, in addition further are recessed to form second slot, 28, the first slots, 27 back-end closures downwards in each base plate 24 front end of the top surface, and front end also is communicated with extraneous and second slot 28.Contiguous root edge place, the rear end, two sides of plastic casing 20 offers a breach 25 respectively, uses during for secondary shielding housing 80 snaps into position.
First shield shell, the 60 inner intercalation spaces 62 that form, 62 rear and front ends, intercalation space all connect with extraneous, are used for being intercalated in it for described plastic casing 20.The roof front end of first shield shell 60 is provided with a pair of cantilever shell fragment 64, separation front end of the top surface both sides and longitudinal extension, and the roof rear end is provided with a pair of banking stop 66, and is corresponding with the position of described cantilever shell fragment 64, and downward-sloping stretching in the intercalation space 62.The diapire rear end hollow out of first shield shell 60, the diapire front end also is provided with a pair of cantilever shell fragment 64, and diapire trailing edge approximate mid-section also bends out downward vertically a limited post 68.The two side of first shield shell 60 also is respectively equipped with a cantilever shell fragment 64, and its length is longer slightly than the cantilever shell fragment 64 that is located at roof and diapire.All bending protrudes out the free end of each cantilever shell fragment 64 to intercalation space 62, is used for replacing the clamping (not shown) with the corresponding wall of the shield shell of a butt connector, realizes that thus the fixing between two connectors cooperates.
See also Fig. 4 again, the shape of secondary shielding housing 80 is corresponding with first shield shell 60, the inner grasping part 81 that forms, and grasping part 81 front ends are in communication with the outside, the rear end is sealed by the rear wall of secondary shielding housing 80 after assembling, in order to clamping, nested first shield shell 60.The free end of the roof of secondary shielding housing 80, diapire and two side corresponding respectively first shield shell 60 each cantilever shell fragment 64 offers the hole 82 of shrinking back, required retraction space when being used to provide cantilever shell fragment 64 to replace clamping with the shield shell of described butt connector.The diapire rear end hollow out of secondary shielding housing 80, the rear end, two side is extended a wall extension 83 respectively downwards, a fastening hole 84 is offered in the rear end of each wall extension 83, the root edge rear and front end of wall extension 83 also protrudes out formation one fixing feet 85 respectively downwards, is used for the electric power connector 100 of the utility model tool shield shell is fixed in (not shown) on a external circuit board.The rear wall of secondary shielding housing 80 is connected as a single entity with roof by a pair of brace 86, before the assembling, as shown in Figure 4, parallel with roof, after the assembling, as shown in Figure 3, be bent to vertical with roof, the both sides of rear wall bend forward respectively near the root edge place extends a folded walls 87, and each folded walls 87 outwards protrudes out and forms a binding block 88.
During assembling, at first with plurality of terminals 40 corresponding build-ins in the terminal groove 23 of plastic casing 20, the intercalation space 62 that then makes plastic casing 20 aim at first shield shell 60 also promotes first shield shell 60 backward, at this moment, the banking stop 66 of first shield shell 60 is along in the roof slip and embedding stopper slot 21 of plastic casing 20, limiting first shield shell, 60 relative plastic casings 20 thus travels forward, the diapire of the limited post 68 and first shield shell 60 is corresponding respectively to be placed in the locating channel 26 and first slot 27 of plastic casing 20, limits first shield shell, 60 relative plastic casings 20 thus and moves backward.Then, first shield shell 60 is aimed at the grasping part 81 of secondary shielding housing 80 and promoted secondary shielding housing 80 backward, at this moment, the internal face of secondary shielding housing 80 is adjacent to the outside wall surface of first shield shell 60 and slides, the diapire of secondary shielding housing 80 is placed in second slot 28 of plastic casing 20, limit secondary shielding housing 80 relative plastic casings 20 thus and move backward.At last, the rear wall of secondary shielding housing 80 is bent downwards, each folded walls 87 correspondence stretches in the breach 25 of plastic casing 20, at this moment, the outside wall surface of folded walls 87 is replaced the internal face of corresponding wall extension 83, the binding block 88 outside build-ins of folded walls 87 limit secondary shielding housing 80 relative plastic casings 20 thus and travel forward in the fastening hole 84 of wall extension 83.
As mentioned above, the electric power connector 100 of the utility model tool shield shell reaches the Shielding Design of secondary shielding housing 80 compositions that closely are coated on first shield shell, 60 outsides by first shield shell 60, can obviously increase the intensity of shield shell, make its with butt connector grafting engagement process in, can bear bigger contact engaging and separating force, and unlikely deformation failure.Meanwhile, the binding block 88 of described secondary shielding housing wall after 80s both sides outwards protrudes out in the corresponding fastening hole 84 that is mounted in the two side, when the fixing feet 85 of two side is plugged on the external circuit board, by the inside backstop of the outside diastole of folded walls 87 and wall extension 83, binding block 88 is mounted in the fastening hole 84 all the time, make secondary shielding housing 80 be in reliable, firm buckling state all the time thus, thereby further prevent the shield shell deformation failure.
