Abstract

An electrical connector (1) includes a first insulative housing (10), a number of contacts (20), and a second housing (30) attached to the first housing. The first housing defines a first and a second cavities (101,103) therein, a number of passageways (104) in communication of the cavities. Each contact received in the passageways has a mating portion (25) extending into the cavities, and further includes a solder portion (21) extending away from the first housing. The second housing defines a number of channels (34) for securely receiving the solder portions therethrough. An interengaging device arranges between the first and second housing such that the second housing is secured attached to the first housing.

Claims

1. An electrical connector, comprising:

a first housing defining a first and a second cavities, a plurality of passageways communicating with the first and the second cavities and arranged in a line;

a plurality of contacts received in the passageways of the first housing, each contact including a solder portion extending away from the first housing;

a second housing attached to the first housing and defining a plurality of channels through which the solder portions of the contacts extend, each channel being vertically aligned with a corresponding passageway.

2. The electrical connector as claimed in claim 1, wherein the first and the second cavities have different dimensions, the first cavity receiving a power segment of a mating connector and the second cavity receiving a signal segment of the mating connector.

3. The electrical connector as claimed in claim 1, wherein the first and second cavities have anti-disorientation devices.

4. The electrical connector as claimed in claim 1, wherein the first housing has guiding posts extending from end walls of the first housing.

5. An electrical connector, comprising:

a first housing defining a plurality of passageways and a pair of guiding posts extending from end walls thereof;

a plurality of contacts received in the passageways, each contact including a solder portion extending away from the first housing;

a second housing attached to the first housing and defining a plurality of channels through which the solder portions of the contacts extend; and

interengaging means arranged between the first and second housings and comprising a receiving space defined in the guiding post of the first housing and a hook formed on the second housing, the hook being securely attached in the receiving space.

6. The electrical connector as claimed in claim 5, wherein the hook projects upwardly from one of opposite ends of the second housing.

7. The electrical connector as claimed in claim 5, wherein the hook further includes a tail portion jointly formed with a lower portion of the guiding post to form a mounting post adapted to be received in a hole of a print circuit board.

8. The electrical connector as claimed in claim 7, wherein a plurality of rib portions is formed on outer surface of the guiding post for engaging with inner wall of the hole defined in the print circuit board.

9. The electrical connector as claimed in claim 7, wherein the second housing comprises a base and a pair of mounting plates projecting sidewardly from opposite ends thereof and being adapted to face the print circuit board.

10. The electrical connector as claimed in claim 9, wherein a through bole is defined in the mounting plate for allowing the tail portion of the hook and the lower portion of the guiding post to extend through.

11. The electrical connector as claimed in claim 7, wherein the lower portion of the guiding post defines a groove for receiving the tail portion of the hook.

12. The electrical connector as claimed in claim 9, wherein the guiding post further forms a flange defining a cutout in a bottom face thereof.

13. The electrical connector as claimed in claim 12, wherein the flange is located around the lower portion of the guiding post and has a larger surface area adapted to face the print circuit board.

14. The electrical connector as claimed in claim 13, wherein the cutout of the flange is adapted for receiving the mounting plate of the second housing.

15. The electrical connector as claimed in claim 5, wherein the interengaging means further includes a block extending from a middle portion of the first housing and an auxiliary hook on the second housing to be securely received in a receptacle of the block.

16. The electrical connector as claimed in claim 5, wherein each contact comprises a retention portion connected a mating portion with the solder portion.

17. The electrical connector as claimed in claim 16, wherein the retention portion of the contact comprises a first retention portion and a second retention portion, the first retention portion having barbs formed opposite sides for engaging with inner walls of the passageway of the first housing.

18. The electrical connector as claimed in claim 17, wherein the second retention portion has protrusions formed on opposite sides thereof, a pair of opposed step sections are defined on inner walls of the channel, the step sections stop the protrusions from moving downwardly.

19. An electrical connector comprising:

an insulative housing;

a plurality of contacts disposed in the housing;

a spacer attached to the housing and aligning solder tails of the contacts;

a pair of hollow guiding posts fanned at two opposite ends of the housing; and

a pair of locking hooks formed at two opposite ends of the spacer and protectively extending into and hidden within the corresponding hollow posts and further latched with the housing.
