Definitions

  • the present invention relates to an electrical connector, and particularly to a micro electrical connector for mating with a complementary connector.
  • a force is certainly needed during an electrical connector connecting or disconnecting with a complementary connector. Normally, this force has little effect on normal size connector, because the normal size connector always has a firm structure. However, a micro connector always has a very weak structure, so it is easily broken when the force is overage.
  • the complementary connector is always arranged in the electronic equipment. If the complementary connector is broken, it is difficult to be replaced and repaired.
  • An object of the present invention is to provide an electrical connector to avoid damage to a complementary connector.
  • an electrical connector adapted for connecting/disconnecting with/from a complementary connector in a front-to-back direction includes a shell, an insulative housing and a number of contacts received in the housing.
  • the shell includes a main body, a connecting tab and a mating portion, the main body further includes a receiving space surrounded by a top surface, a bottom surface, and a pair of lateral surfaces.
  • the connecting tab only connects with one edge of said surfaces of the main body.
  • the mating portion extends from the connecting tab in the front-to-back direction.
  • the insulative housing includes a base portion receiving in the receiving space of the main body of the shell and a tongue portion extending from the base portion along the mating direction received in the mating portion of the shell.
  • FIG. 1 is an assembled, perspective view of an electrical connector in accordance with the present invention
  • FIG. 2 is an exploded, perspective view of the electrical connector shown in FIG. 1;
  • FIG. 2 is a view similar to FIG. 2, but taken from a different aspect
  • FIG. 4 is a perspective view of a shell of the electrical connector
  • FIG. 5 is a partially assembled, perspective view of the electrical connector
  • FIG. 6 is another partially assembled, perspective view of the electrical connector.
  • FIG. 7 is a view similar to FIG. 5, but taken from a different aspect.
  • an electrical connector 100 in accordance with the present invention comprises a metal shell 1, an insulative housing 2, a plurality of contacts 4 received in the insulative housing 2, a pair of locking member 3, and a stopping block 5.
  • the electrical connector 100 is in accordance with a micro USB standard.
  • the electrical connector could be provided as other types.
  • the metal shell 1 comprises a top shell 11 and a bottom shell 12.
  • the top shell 11 comprises a main body 111, a connecting tab 115 and a mating portion 112.
  • the main body 111 comprises a top surface 113, a pair of lateral surfaces 114 and a bottom surface 117 (shown in FIG. 4).
  • the top surface 113 comprises a pair of first gaps 1130 and a second gap 1131 located more adjacent to the connecting tab 115 than that of first gaps 1130.
  • Each lateral surface 114 defines a first cutout 1140 and a second cutout 1141.
  • the bottom surface 117 has a jag (not labeled) thereon and a pair of resilient tabs 1170 bent inwardly from the opposite edges of the jag of the bottom surface 117.
  • the connecting tab 115 is bent downwardly from the main body 111 along an up-to-down direction.
  • the mating portion 12 extends forwardly from the connecting tab 115 along a front-to-back direction. Thereby, the mating portion 112 can move along the up-to-down direction relative to the main body 111 through the connecting tab 115.
  • the connecting tab 115 also can extend from the lateral surface 114, accordingly, the mating portion 112 move along a lateral direction relative to the main body 111.
  • a pair of rectangular cutouts 116 are defined at a portion where the connecting tab 115 and the main body 111 join.
  • the rectangular cutouts 116 are applied for decreasing the intension of the connecting tab 115, therefore, the connecting tab 115 can be bent more easily.
  • the mating portion 112 defines a mating cavity 118, a pair of positioning tabs 1181 extending backwardly from rear edge thereof, and a pair of receiving cutouts 1180 at a surface of the mating cavity 118.
  • the bottom shell 12 comprises a bottom wall 121, a front wall 123, a rear wall 122 and a pair of lateral walls 124. These walls together define a receiving cavity (not labeled).
  • the rear wall 122 of the bottom shell 12 has a receiving hole 1220 for cable (not shown) passing through.
  • Each lateral wall 124 forms a block 1240 corresponding to the first cutout 1140 of the top shell 11 and a third cutout 1241 overlapped the second cutout 1141 of the top shell 11.
  • the bottom wall 121 also defines a third gap 125 corresponding to the second gap 1131 of the top shell 11.
  • Each contact 4 comprises a contacting portion 43, a tail portion 41 and a retaining portion 42 connecting the contacting portion 43 and the tail portion 42.
  • Each tail portion 41 is bent from the retaining portion 42 downwardly/upwardly along the up-to-down direction. So, the space between adjacent tail portions 41 becomes bigger, and it facilitates to soldering the cable to the tail portions 41.
  • Each locking member 3 comprises a locking arm 31, a resilient arm 33 parallel with the locking arm 31 and a U-shape retaining arm 32.
  • the locking arm 31 and the resilient arm 33 extend from the U-shape retaining arm 32 in a same direction.
  • the locking arm 31 forms a bar 35 at the distal end thereof.
  • the bar 35 forms an incline guiding face 36 thereon.
  • the retaining arm 32 and the locking arm 31, respectively, forms a stopping projection 34, 37 for stopping the locking member 3 has a further movement into the housing 2.
  • the insulative housing 2 comprises a base portion 21 and a tongue portion 22 extending forwardly from the base portion 21 along the front-to-back direction.
  • the base portion 21 comprises a plurality of receiving passageways 211 therein, and a pair of receiving slits 213 at the opposite ends of the receiving passageways 211.
  • a pair of positioning blocks 214 is, respectively, beside corresponding receiving slits 213.
  • Each positioning block 214 comprises a receiving portion 216 for fixing the connecting tab 112 of the top shell 11.
  • the base portion 21 defines an upper engaging hole 215 and a lower engaging hole (not shown), respectively, defining at the top face and the bottom face thereof.
  • the upper engaging hole 215 communicates with the receiving passageways 211, the lower engaging hole is separated with the receiving passageways 211.
  • the tongue portion 22 defines a plurality of receiving slots 221 communicating with corresponding receiving passageways 211.
  • a pair of the projecting portions 222 are defined at the opposite ends at the tongue portion 22 and form a pair of holding slits 223 with the tongue portion 22.
  • the holding slits 223 are used to receiving the distal ends of the locking members 3, and restrict the movement of the locking member 3 in the lateral direction.
  • the base portion 21 further forms a pair of retaining projections 212 at the opposite lateral faces.
  • the stopping block 5 receiving in the upper engaging hole 215 comprises a stopping section 51 and an engaging section 52.
  • the contacts 4 are inserted into the housing 2 along the front-to-back direction.
  • the retaining portion 42 of each contact 4 is received in corresponding receiving passageways 211, the contacting portion 43 extends into corresponding receiving slot 221 with tip end exposed outside, and the tail portion 41 is exposed beyond the housing 2.
  • the stopping block 5 is inserted into the housing 2 through the upper engaging hole 215 along the up-to-down direction.
  • the engaging section 52 of the stopping block 5 engages with the retaining portions 42 of the contacts 4, and the stopping section 51 engages with the inner face of the upper engaging hole 215.
  • the upper face of the stopping block 5 is lower than the upper face of the base portion 21 of the housing 2.
  • the locking members 3 are inserted into the receiving slits 213 with the distal end extending into the holding slits 223 and the stopping projections 34, 37 engaging with the rear face of the housing 2.
  • the resilient arms 33 are exposed out of the housing 2.
  • the resilient tabs 1170 are bent downwardly because of the pressure on the housing 2.
