[embodiment]
Please refer to Fig. 1 and shown in Figure 2, the utility model micro coaxial cable connector assembly comprises terminal module 1, accommodate and the insulating body 2 of fixed terminal module 1, be connected the cable 3 of terminal module 1 rear end and cover the metal shell 4 of insulating body.
Terminal module 1 is made up of two row's conducting terminals 11, above row's terminal 11 be fixed in the upper surface of collets 12 (its for last collets), below row's terminal 11 be fixed in the lower surface of another collets 12 (its under collets).These two collets 12 all form in the mode that edge buries moulding (insert molding).The lower surface of last collets 12 is provided with a pair of projection 120, and the upper surface of following collets 12 is provided with a pair of circular hole 121 of projection 120 of accommodating so that upper and lower collets 12 are installed as one.
These all terminals 11 can be divided into 4 couples of differential pair terminal 11a and 11 other terminal 11b of high frequency signals such as transmission of video/audio frequency, and these other terminals 11b comprises the power supply terminal that is used to transmit power supply, be used for the earth terminal of ground connection and be used to transmit other signal terminal of low frequency signal.
Please in conjunction with Fig. 2 and shown in Figure 3, each differential pair terminal 11a comprise front end extend collets 12 with and another connector (not shown) the elasticity docking section 111, the rear end that connect extend collets 12 rears in order to the lead holding parts 113 of connection cable 3 and the connecting portion 112 between elastic joint part 111 and lead holding parts 113, connecting portion 112 both sides are provided with sawtooth (sign) so that the terminal 11 firm collets 12 that are incorporated into.Lead holding parts 113 comprise be positioned at its end in order to the clamping part 1132 of clamping lead and away from adjacent differential pair terminal 11a to strengthen the rake 1131 of adjacent clamping part 1132 spacings, each clamping part 1132 comprises a pair of bent sheet 11321 that is positioned at its both sides and bent sheet 11321 is enclosed the lead accepting groove 11322 that forms by this.
