1. Field of the Invention
The present invention generally relates to an electrical connector and more particularly to an electrical connector with a spacer which is mechanically retained to an insulative housing of the electrical connector.
2. Description of Related Art
Chinese patent No. 201570629U, published on Sep. 1, 2010, discloses an electrical connector including an insulative housing, a plurality of contacts retained in the insulative housing, a spacer mounted to the insulative housing and a shield shell enclosing the insulative housing. The insulative housing includes a body portion and a tongue extending forwardly from the body portion. The spacer has a plurality of through holes passing therethrough. The contacts include a first group of contacts having a plurality of first contacts, and a second group of contacts located under the first group of contacts and having a plurality of second contacts. The first contact includes a first retaining portion retained in the insulative housing, a first extending portion extending downwardly and vertically from a rear of the first retaining portion and into the through hole, and a first soldering portion extending downwardly from the first extending portion and extending out of the through hole downwardly. The second contact includes a second retaining portion retained in the insulative housing, a second extending portion extending downwardly from the retaining portion and into the through hole of the spacer and a second soldering portion extending downwardly from the second extending portion and out of the spacer. The first extending portions are arranged adjacent to the second extending portions. As this result, the heavy cross-talk between the first and second extending portion may occure the data transmission.
So, an improved connector is needed.
The present invention provides an electrical connector, which comprises an insulative housing, a plurality of contacts received in the insulative housing and a spacer mounted into the insulative housing for retaining the contacts. The contacts include a first group of contacts having a plurality of first contacts and a second group of contacts having a plurality of second contacts. The first contacts each have a first extending portion extending vertically, and the second contacts each have a second extending portion extending vertically. The first and second extending portions are arranged in two rows along a front-to-rear direction. The spacer has a base and a lump extending upwardly from the base. The lump separates the first extending portion from the second extending portion along the front-to-rear direction.
Other objects, advantages and novel features of the present invention will become more apparent from the following detailed description of the present embodiment when taken in conjunction with the accompanying drawings.
Reference will now be made to the drawing figures to describe the preferred embodiment of the present invention in detail.

The first step 12 has a plurality of first receiving passageway 121 passing therethrough along a front-to-rear direction and be communicated with the first receiving slot 1111. The second step 13 has a plurality of second receiving passageway 131 passing therethrough along the front-to-rear direction and be communicated with the second receiving slot 1121. The left and right wall 103, 104 each have a protruding portion 106 extending downwardly therefrom and a positioning block 107 extending outwardly from the protruding portion 106 and beyond the left and right walls 103, 104. Each positioning block 107 has a mounting hole 1072 passing therethrough along an upper-to-down direction. The protruding portion 106 has a retaining slot 1061 passing through the protruding portion 106 downwardly and inwardly. The positioning block 107 has a plating portion 1071 extending horizontally therefrom. An attaching space 110 is formed between the plating portions 1071 and the left and right walls 103, 104 and behind the protruding portion 106. A supporting portion 108 extends forwardly from a bottom edge of the front wall 101 and connects with front edges of the two plating portions 1071. The supporting portion 108 has a pair of positioning posts 1081 extending downwardly therefrom. A retaining space 1082 is formed between the supporting portion 108 and the body portion 10.

The base 31 has a plurality of through holes 311 passing therethrough and a pair of latching blocks 312 extending outwardly from two sides thereof. The positioning portion 32 has a plurality of retaining slots 321 depressed forwardly from a rear thereof and passing therethrough along the upper-to-down direction and a pair of mounting portions 322 extending outside from two sides thereof.
The spacer 3 is mounted to the receiving space 105 of the insulativer housing 1 along the down-to-upper direction. The base 31 abuts against a rear of the front wall 101 of the insulative housing 1 forwardly. The lump 33 resists a rear of the first step 12 upwardly. The latching blocks 312 are received in the retaining slots 1061 and the mounting portion 322 is received in the attaching space 110. The mounting portion 322 is located between the plating portion 1071 and the left and right walls 103, 104. A front of the base 31 of the spacer 3 is received in the retaining space 1082 partly.

The second group of contacts 22 includes a plurality of second contacts 220. The second contacts 220 each have a second retaining portion 222 retained in the second receiving passageway 131, a second contacting portion 221 extending forwardly from the retaining portion 222 and received in the second receiving slot 1121, a second extending portion 223 extending backwardly and vertically from a rear of the second retaining portion 222 and extending into the through hole 311 of the spacer 3, and a second soldering portion 224 extending downwardly from the extending portion 223 and extending out of the through hole 311. The second retaining portions 222 are arranged in a row along a transverse direction and the second extending portions 223 are arranged in three rows along an inserting direction. The second group of contacts 22 is disposed in the front of the lump 33 of the spacer 3. The first extending portion 213 is located in the rear of the lump 33 and the second extending portion 223 is located in the front of the lump 33 respectively. The height of the second retaining portion 222 is lower than the height of the lump 33 along the upper-to-down direction. The lump 33 separates the second contacts 220 from the first contacts 210 along the front-to-rear direction.
The shield shell 4 encloses around the insulative housing 1 and is made by a metal plate. The shell 4 includes a top face 41, a bottom face 42 opposite to the top face 41, two side faces 43 connecting the top face 41 and the bottom face 42 and a back cover 44 extending downwardly and vertically from the top face 41, which cooperatively surround an inserting space 45. The side face 43 has a limiting block 431 extending outside thereof and a first retaining tail 432 extending downwardly from a rear thereof. The first retaining tail 432 is located behind the bottom face 42. The side face 43 has a second retaining tail 433 backwardly then extending downwardly and vertically from a front thereof. The second retaining tail 433 abuts against the out side of the side face 43. The back cover 44 has a pair of the locking portions 411 extending forwardly and vertical from two sides thereof. The locking portion 411 has a latching slot 4111 passing therethrough. The latching slot 4111 abuts against the side face 43. The limiting block 431 is received in the latching slot 4411. The insulative housing 1 is mounted into the shell 4 along the rear-to-front direction, and the tongue 11 extends into the inserting space 45. The supporting portion 108 resists the bottom face 43 of the shell 4 upwardly and the back cover 44 resists the rear of insulative housing 1. The first retaining tail 432 extends through the mounting hole 1072 downwardly.
The electrical connector 100 comprises a spacer 3 having a lump 33 extending upwardly thereof. The lump 33 separates the adjacent first and second groups of contacts 21, 22 from each other along the front-to-rear direction to improve signal transmission quality of the electrical connector 100.
