Electrical connector with a stable structure

An electrical connector, comprising:

• a first housing having a mating surface and a mounting surface at two sides thereof;
• a second housing retained to the first housing and having a joint surface to joint with the mounting surface;
• wherein the first housing defines a locking slot and a position slot respectively recessed from the mounting surface, and the second housing is formed with a spring arm locking with the locking slot to prevent the second housing from departing from the first housing along an assembling direction of the second housing, and a position projection engaging with the position slot to prevent the second housing from moving along a deformed direction of the spring arm;
• and
• a plurality of contacts retained to the first housing, the first housing has a body portion and a tongue upwardly extending from the body portion, and the tongue defines a plurality of passageways at two sides thereof and extending through the body portion to retain the contacts, the position slots are located at two outer sides of the passageways, and the locking slot upwardly extends through the body portion, wherein the second housing defines a receiving cavity extending along a width direction thereof and a plurality of through holes extending therethrough and communicating with the receiving cavity, wherein the adjacent two through holes define a distance which is larger than that of adjacent two passageways, and each contact has a retaining portion retained in the body portion, a contact portion extending to the tongue from one end of the retaining portion, a bending portion obliquely extending from another end of the retaining portion to be received in the receiving cavity, and a tail portion extending through the through holes, the adjacent tail portions define a distance which is larger than that between adjacent contact portions.

An electrical connector comprising:

• a first insulative housing defining a mating port;
• a second insulative housing defining a mounting port opposite to the mating port in a downward direction;
• a plurality of contacts each assembled to both said first insulative housing and said second insulative housing under condition that each of said contacts includes a mating section exposed on the mating port and a mounting section exposed on the mounting port;
• and
• a metallic shell essentially fully enclosing both said first insulative housing and said second insulative housing therein;
• wherein said shell is assembled and secured to the first insulative housing in said downward direction while said second insulative housing is assembled and secured to the first insulative housing in an upward direction opposite to said downward direction;
• wherein each of said first insulative housing and said second insulative housing define a protrusion, under condition that the protrusion of the insulative first housing is aligned with the protrusion of the second insulative housing in the upward direction, and said shell defines a downward long slot to receive both said protrusions, wherein the first housing defines a locking slot recessed from the mounting surface and a pair of blocks projecting into the locking slot from the inner walls respectively and the second housing is formed with a pair of spring arms, and each spring arm has a hook extending outwardly to lock with the blocks, and said locking slots and spring arms are formed on long sides of both said first insulative housing and said second insulative housing while said protrusions are formed on short sides of said first insulative housing and said second insulative housing, wherein the shell includes a front wall, a rear wall and a pair of side walls, and the front wall is formed with a first mounting leg extending downwardly, and the rear wall is formed with a pair of second mounting legs extending downwardly and located at two sides of the first mounting leg along a width direction of the first housing, wherein the mounting legs have downward hooks for locking to a printed circuit board on which the second insulative housing is seated while the spring arms of the second insulative housing have upward hooks for latching to the first insulative housing.
