[embodiment]
See also Figure 1 and Figure 2, the utility model electric connector 100 can be electrically connected between object and the printed circuit board (PCB) 300, and in the present embodiment, object is that example describes with the camera model; Electric connector includes insulating body 1, be immobilizated in several terminals 2 in the insulating body, be installed on first housing 3 on the insulating body and be sheathed on second housing 4 on first housing movably.
Insulating body 1 is the lengthwise shape, terminal 2 is arranged on the insulating body along longitudinally, each terminal 2 one end is provided with and extends insulating body outer elastic arm 21, the other end and be provided with the weld part 22 that the elastic arm with terminals of adjacent is provided with at interval, in the present embodiment, terminal 2 is overmolded on the insulating body 1 and forms a body unit, this body unit is placed on the printed circuit board (PCB) 300, and is connected on the printed circuit board (PCB) by weld part 22.The lengthwise two ends of insulating body 1 have for first housing 3 inserts the side rib of installing 11, form mounting groove 110 on this side rib, first housing 3 is for shaped as frame and have sidewall 31, the root edge of sidewall has the fixing pin 310 that is immobilizated in the mounting groove, thereby the common host cavity 101 of accommodating camera model 200 that forms of this first housing and body unit, the elastic arm of terminal 2 protrudes into host cavity 101 and has the contact site relative with camera model 211, with realize with camera model on electrical contact the between the corresponding conducting strip (not shown).
During assembling, earlier that first, second housing is combined, body unit is installed on first housing again, can finish the assembly working of the utility model electric connector.See also Fig. 1, Fig. 3 and shown in Figure 4, in order to realize that electric connector 100 electrically connects camera model 200, the function of printed circuit board (PCB) 300, at first, electric connector is installed on the printed circuit board (PCB), again the opening of camera model from host cavity 101 inserted, this moment, the merging that matches of second housing 4 and first housing was in primary importance, camera model can insert in the host cavity and be positioned at primary importance at this moment, described location division 41 is positioned at the side of stop section 311 away from printed circuit board (PCB), registration arm 43 is extended to the second arm place, one side, on the shoulder 201 that presses on camera model, and camera model does not electrically contact with terminal, can realize pre-determined bit, thereby prevent camera model too early contravention of pressing under unnecessary situation camera model.
See also Fig. 5 and shown in Figure 6, second housing 4 oppositely moves to the second place from primary importance with respect to first housing 3 along the D direction, in the motion process, registration arm 43 presses on the shoulder 201 of camera model all the time, thereby driving this camera model moves to terminals side, this stop section 311 is guided and slipped in location division 41 by the inclined-plane of stop section, be positioned at the outstanding opposite side (promptly arriving the second place) in stop section until location division 41, this moment, second housing was fixed on first housing, this location division is blocked by this stop section 311, can prevent that second housing 4 from taking place from the second place moving to the not operation person wish of primary importance, second housing 4 also is butted on the printed circuit board (PCB) in the present embodiment, helps location division 41 is locked between stop section 311 and the printed circuit board (PCB) 300.After second housing 4 moves to the second place with camera model, camera model extruding and electrical contact terminal.
Because second housing 4 can slide and camera model 200 is pressed to the bottommost of host cavity 101 along first housing 3, in the regime of elastic deformation of terminal elastic arm, make between camera model and the terminal closely to contact.The size of registration arm 43 can design according to the minimum constructive height h (please join shown in Figure 1) of shoulder 201, when the shoulder of camera model becomes big, the registration arm 43 of second housing 4 can drive first, second arm strain of second housing under the reaction force of terminal, make registration arm firmly press on the camera model all the time, thereby the variation that strain adapts to the shoulder height takes place by self in second housing, the length that need not change registration arm is with suitable different shoulder height, and the contact stabilization between camera model and the electric connector is reliable and universal performance is higher.Second arm 402 of second housing 4 also has self-align 41 operating portion that protrudes out 411, and operator can be used instrument etc. and make the first arm strain, thereby the location division breaks away from the restriction of stop section from the second site reversion to the primary importance.
Please consult shown in Figure 2 again, side rib 11 two ends of insulating body 1 have the wall extension 111 that forms along on the horizontal direction perpendicular to longitudinally, when second housing 4 drives the camera model 200 arrival second places, the basal surface of this camera model can be resisted against on the wall extension 111, thereby prevents that the terminal pressurized is excessive.Please in conjunction with shown in Figure 5, the sidewall 31 of first housing 3 is provided with the ground strip 315 that protrudes out in host cavity, and this ground strip presses on the outside of camera model 200, the outside noise of maskable.
See also Fig. 7 and shown in Figure 8, first, second housing of the electric connector 400 of another kind of execution mode is different from the embodiment described above, and other elements such as terminal are then roughly the same with above-mentioned execution mode.The stop section 511 of first housing 5 outwards stamps out a shell fragment from first housing and forms, when second housing 6 when first housing 5 slides into the second place, the location division 61 of this second housing connects with the side of stop section 511 than projection, to lock second housing; And the registration arm 63 of second housing presses on the shoulder 201 of camera model, and camera model is firmly contacted with terminal.Described terminal also can be directly welded on the printed circuit board (PCB), does not need to be manufactured in together with the insulating body moulding.
