Abstract
Abstract An electrical connector includes a plug (10) having a number of contact pins (12) and a jack (15) having a corresponding number of receptacle contacts (24). Each of the receptacle contacts (24) has a parallel portion (24c) and a widened portion (24b). A contact pressing member (22) having partition walls (22b) is movable so that when the contact pressing member (22) is in a first position (Figure 8A), the partition walls (22b) are positioned adjacent the parallel portions (24c) of the receptacle contacts (24) to allow an easy insertion of the contact pins (12) (Figure 8B) and, when the contact pressing member is moved to a second position (Figure 8C), the partition walls (22b) are moved to the widened portions (24b) of the receptacle contacts (24) so that they urge the widened portions (22b) together and, therefore, the receptacle contacts (24) are pressed into tight contact with the contact pins (12).

215 words
An electrical connector comprising: a) a plug assembly (10) having a number of contact pins (12); b) a jack assembly (15) including: a corresponding number of resilient receptacle contacts (24), each of the receptacle contacts (24) having a gap at one end (24a) into which, in use, the corresponding contact pin (12) is inserted, so that the contact pins (12) simultaneously come into electrical contact with the receptacle contacts (24), the receptacle contacts (24) having parallel portions (24c) in which their outer surfaces are parallel and a widened portion (24b) in which the width between their outer surfaces is greater than that in the parallel portion, and a contact pressing member (22) having partition walls (22b) and being movable between a first position and a second position, in the first position, the partition walls (22b) are located adjacent the parallel portions (24c) of the receptacle contacts (24) to allow easy insertion of the contact pins (12) and in the second position, the partition walls (22b) engage the widened portions of the receptacle contacts (24b) and urge them together so that the receptacle contacts (24) are pressed into tight contact with the contact pins (12); and, c) means (21f, 22d, 30, 31, 32) for moving the contact pressing member (23) between its first and second positions.
Claim 2
Dependent Claim
215 words
An electrical connector comprising: a) a plug assembly (10) having a number of contact pins (12); b) a jack assembly (15) including: a corresponding number of resilient receptacle contacts (24), each of the receptacle contacts (24) having a gap at one end (24a) into which, in use, the corresponding contact pin (12) is inserted, so that the contact pins (12) simultaneously come into electrical contact with the receptacle contacts (24), the receptacle contacts (24) having parallel portions (24c) in which their outer surfaces are parallel and a widened portion (24b) in which the width between their outer surfaces is greater than that in the parallel portion, and a contact pressing member (22) having partition walls (22b) and being movable between a first position and a second position, in the first position, the partition walls (22b) are located adjacent the parallel portions (24c) of the receptacle contacts (24) to allow easy insertion of the contact pins (12) and in the second position, the partition walls (22b) engage the widened portions of the receptacle contacts (24b) and urge them together so that the receptacle contacts (24) are pressed into tight contact with the contact pins (12); and, c) means (21f, 22d, 30, 31, 32) for moving the contact pressing member (23) between its first and second positions.
Claim 3
Dependent Claim
26 words
