Also with reference to Figure 28-31, keeper 214 is attached to the first side 230 and the second side 234 being adjacent to the lead frame assembly 216 arranged.First breech lock 231 and the second breech lock 235 are complementally aimed at the layout of the opening 252,254 in keeper 214.This allows the first breech lock 231 and the second breech lock 231 to engage the opposite end of keeper 214.First breech lock 231 and the second breech lock 235 are used as the retention system of keeper 214.In order to be attached keeper 214, second (or rear portion) breech lock 235 inserts corresponding second opening (or groove) 254 (as shown in Figure 28-30) on the second extension 250 of keeper 214.Keeper 214 then on the direction towards the first side 230 (as indicated by the arrow 255) reduce (or being rotated counterclockwise) in place.By providing power, deflection enters undercut area 229, to be engaged to corresponding first opening 252 on the first extension 248 by first (or top) breech lock 231 in the comer area (between the first extension 248 and the second extension 250) of keeper 214.After power removes, keeper 214 is by resilience and will be retained to lead frame assembly 216 (see Figure 31, in order to clear, hidden line being shown).Top latches 231 is departed from the material thickness of manager 214 to guarantee the ground plane of electrical contact to PCB.Will appreciate that, in alternative embodiments, keeper 214 is alternately assembled by first keeper 214 being attached to top latches 231 and being then attached to rear portion breech lock 235.
Keeper 214 guarantees that when lead frame assembly 216 is received in connector modules unit 212 lead frame assembly 216 is adjacent one another are to form back panel connector 210.One end of connector modules unit 212 comprises the socket of applicable size and dimension, to receive contact from matching connector.
Referring now to Figure 32, the perspective view of back panel connector 310 is according to a fifth embodiment of the present invention shown.Back panel connector 310 and back panel connector 10,110 similar.Back panel connector 310 is configured to be connected with mating electrical connector 328.
Back panel connector 310 (for example, it can be rigging-angle connector) comprises connector modules unit (or housing) 312, keeper 314 and multiple lead frame assembly 316.Lead frame assembly 316 is fixedly arranged for adjacent one another are and supported by keeper 314.Connector modules unit 312 receives multiple lead frame assembly 316 and provides the electrical connection between lead frame assembly 316 and mating electrical connector 328 (for example it can be vertically hold seat).
Also with reference to Figure 33 and 34, each lead frame assembly 316 supports multiple conductive contact 318 as above described in previous embodiment.Each contact 318 has terminal end 320 and abutting end 322.Terminal end 320 extends from terminals side 324 (contrary with the first side 330) and is configured to engage with printed circuit board (PCB) or other electronic equipment (not shown).Abutting end 322 extends from cooperation side 326 (contrary with the second side 334) and is configured to engage with connector modules unit 312.
A difference between lead frame assembly 316 and lead frame assembly 116 is the orientation of the second outstanding element.Similar with the second outstanding element in the second embodiment, the on the second side 334 second outstanding element can be breech lock (or hook-like part) 335 and align structures 337.The align structures 337 of the second side 334 of lead frame assembly 316 is seen best for relative to each other interlocking in Figure 35 and 36.It should be noted that in alternative embodiments, align structures 337 can be configured to breech lock.Should also be appreciated that, be in staggered directed although accompanying drawing shows only outstanding element 337, outstanding element 335 (separately or combine with outstanding element 337) also can be arranged in staggered orientation.And, the first side 330 that alternate embodiment also can be included in lead frame assembly 316 has the outstanding element of decussate structure.
Also with reference to Figure 35 and 36, keeper (or guard shield) 314 comprises the first extension 348 and the second extension, extension 350, second and has the second opening 354 as above described in previous embodiment.A difference between keeper 314 and keeper 114 is the orientation of the second opening 354.Second opening 354 is correspondingly staggered to receive the outstanding element on the second side 334.Although it should be noted that accompanying drawing shows only the second extension and has staggered opening, the alternate embodiment on the first extension with staggered opening can be expected.
Be to be understood that, before to describe be only explanation of the present invention.Variously to substitute and modification can be designed by those skilled in the art not departing from situation of the present invention.Therefore, by comprising, fall within the scope of claims all this substitutes, modification and change in the present invention.
