See also Fig. 1 to shown in Figure 3, the utility model SATA type electric connector 10 comprises insulating body 20, some the first terminals 30, some second terminals 40 and a pair of locked instrument 50.This electric connector 10 is assembled on the printed circuit board (PCB) (not shown).
This insulating body 20 comprises a long and narrow docking section 200 and a long and narrow main body 202, and this docking section 200 comprises an interface 21 and pair of sidewalls 204,206.This main body 202 also has a junction 22, is provided with two accepting grooves 26 between interface 21 and junction 22, and wherein the length of an accepting groove 26 is longer than another accepting groove.Sidewall 204 is thicker and be provided with the some passages 24 that link to each other with accepting groove 26 than another sidewall 206.This accepting groove 26 can be accommodated a pin connector that connects (not shown), in this way connector 10 and butt connector is electrical connected.
This insulating body 20 also has a pair of guidance part 28 that is shaped in sidewall.This guidance part 28 is arranged at contiguous interface 21 places, and it has one and extends upward the tapered portion 280 that interface 21 connects with guide connector 10 and butt connector.Contiguous junction 22 places are provided with a pair of fixed part 29 on the sidepiece 23 of this insulating body 20, and this fixed part 29 is arranged at corresponding guidance part 28 belows and each fixed part 29 is provided with a holding slot 290, is provided with step 292 in the bottom of holding slot 290.
See also Fig. 2 and shown in Figure 3, this the first terminal 30 and second terminal 40 have similar configuration, each terminal has included free end 300,400, contact site 301,401, elastic arm 302,402, by elastic arm 302,402 downward first holding parts 303,403 that extend, second holding parts 305,405 with 303,403 phase deviations of first holding parts, the bending part 304,404 that first holding parts 303,403 is connected with second holding parts 305,405, and the afterbody 306,406 that links to each other with second holding parts 305,405 respectively.A pair of first jut 3031,4031 is arranged on the pair of sidewalls of first holding parts 303,403.A pair of second jut 3051,4051 is arranged on the pair of sidewalls of first holding parts 305,405.This afterbody 306,406 has a pinprick hole, and is provided with a pair of arched arm 3060,4060 to match with through hole on the printed circuit board (PCB).
This bending part 304,404 is a S shape, and it has respectively towards the first of contact site 301,401 bendings and connects the second portion of second holding parts 305,405 respectively.The S shape bending part 304 of the first terminal 30 and the S shape bending part 404 of second terminal 40 are oppositely arranged, and that is to say, this S shape bending part 304 and S shape bending part 404 are respectively towards two side 204,206 bendings of insulating body 20.
During assembling, this first terminal 30 and second terminal 40 are alternately in interface 22 is assembled into passage 24.As Fig. 5 and shown in Figure 6, because first jut 3031,4031 cooperates with main body 202 interferences of insulating body 20, this first holding parts 303,403 can be guaranteed the stable fixing of the main body 202 of first and second terminal 30,40 and insulating body 20.These elastic arm 302,402 parts are projected in the accepting groove 26, and contact site 301,401 is exposed in the accepting groove 26 and contacts with the terminal with the banjo connector.This free end 300,400 is in the import department of contiguous accepting groove 26 on the insulating body 20.
This S shape bending part 304,404 also is contained in the passage 24 and is exposed to the junction 22 of contiguous insulating body 20.Because second jut 3051,4051 cooperates with insulating body 20 interferences, this second holding parts 305,405 is stabilized and is immobilizated in the passage 24.Be appreciated that because S shape bending part 304,404 connects first holding parts 303,403 and second holding parts 305,405, so this S shape bending part 304,404 is immobilizated in the insulating body 20 with being stabilized.The afterbody 306,406 of this needle-like eyelet extends beyond the junction 22 of insulating body 20 downwards to be pressed in the through-holes of printed circuit boards from second holding parts 305,405.
With respect to the normal signal/power terminal in second terminal 40, each earth terminal 41 has long afterbody 416.As shown in Figures 7 and 8, after earth terminal 41 was held in the corresponding passage 24, the distance between the contact site 411 of earth terminal 41 and the interface 21 of insulating body was shorter than the contact site 401 of signal/power terminal 40 and the distance between the interface 21.That is to say, be exposed to each contact site 411 in the passage 24 than signal/power terminal 40 more close interfaces 21.So before the contact site 301,401 of signal/power terminal contacted with the corresponding terminal of butt connector is electrical, the contact site 411 of earth terminal 41 just at first contacted with the corresponding earth terminal of butt connector and sets up grounding path.Be appreciated that and have only when butt connector separates with connector 10 that this grounding path side is destroyed.
As shown in Figures 2 and 3, a pair of locked instrument 50 is by a sheet metal punch forming and have and the similar configuration of the afterbody 306,406 of first, second terminal 30,40.Each locked instrument 50 comprises an a pair of shoulder 51 and a foot 52.This foot 52 is provided with bigger pinprick hole 53, aperture.
For locked instrument 50 is assembled in the holding slot 290, provide the assembly space of locked instrument 50 in the top of the below of guidance part 28 and fixed part 29.The shoulder 51 of this locked instrument 50 is resisted against on the step 292 of holding slot 290 inside, and junction that holding slot 290 stretches out insulating body 20 is downwards run through to be pressed on the printed circuit board (PCB) in the corresponding through hole in the foot 52 of this locked instrument 50.
The utility model electric connector is that compared to the advantage of prior art its first and second terminal 30,40 is provided with S shape bending part 304,404.Because first and second terminal 30,40 is provided with S shape bending part 304,404, so the length that needn't reduce terminal 30,40 also can reduce the height of this terminal and this electric connector 10, make terminal still have sufficient length to obtain required resistance to satisfy predetermined resistance needs that comprise the interconnected systems of SATA connector.In addition, because first jut 3031,4031 is outstanding on the pair of sidewalls of first holding parts 303,403, second jut 3051,4051 is outstanding on the pair of sidewalls of second holding parts 305,405, so this first and second terminal 30,40 can be immobilizated in the insulating body 20 with being stabilized.Therefore the performance of this connector 10 is guaranteed effectively.
On the other hand, this S shape bending part 304,404 also can be other curved shape and neither reduces terminal length to reach, and can reduce the purpose of terminal height again.For example, N shape bending part or Z-shaped bending part extend again downwards towards junction 22 bendings towards interface 21 earlier, also can realize above-mentioned purpose.
