The present invention generally relates to connectors suitable for transmitting data, more specifically to input/output (I/O) connectors with high-density configuration and high data transmitting rate.
U.S. Patent Publication No. 20120164860A1 to Chien-Chiung Wang et al. published on Jun. 28, 2012 discloses a plug connector latched with a complementary connector. The plug connector comprises a housing and a latch mechanism mounted on the housing, and the complementary connector defines a latching tab having a latching hole, the housing defines a latching nose for latching with the latching tab. The plug connector has a protrusion promoted by the latch mechanism and actuating the latching tab disengaging from the latching nose. However the plug connector has a complex structure with much components.
An electrical connector assembly having an improved latch mechanism is desired.
Accordingly, an object of the present invention is to provide an electrical connector assembly with an improved latch mechanism.
In order to achieve the above-mentioned objects, an electrical connector assembly comprises: a housing having a channel formed on a top surface thereof and extending along a mating direction, a latch mechanism received in the channel and being capable of sliding in the channel, and a spring received in the indentation. An indentation is formed in the channel. The spring is limited by the latch mechanism along a front to rear direction. The latch mechanism defines a block extending into the indentation and attached to a front end of the spring.
Other objects, features and advantages of the invention will be apparent from the following detailed description taken in connection with the accompanying drawings.
Reference will now be made to the drawing figures to describe the present invention in detail.

The second shield part 1b defines a top surface comprising a first surface 11 and a second surface 12. The first surface 11 is located below and disposed in front of the second surface 12. A pair of screw holes 1217 are recessed on two lateral sides of the second shield part 1b and throughout the second shield part 1b along a vertical direction. The second shield part 1b defines a channel 121 extending from the second surface 12 to the first surface 11 along a rear to front direction and with different widths. The channel 121 comprises a receiving slot 1210 on the second surface 12, a positioning slot 1215 located behind and communicated with the receiving slot 1210, an extension slot 1211 extending forwards from the receiving slot 1210, a fixing slot 1212 extending forwards from the extension slot 1211. The fixing slot 1212 has a depth becoming deeper and deeper from a rear-to-front direction, and includes a front narrow section and a back wide section. A protrusion 1214 is disposed in the receiving slot 1210, and an indentation 1216 is defined in the protrusion 1214, the indentation 1216 is extending forwards and communicated with the extension slot 1211. The extension slot 1211 has a width wider than that of the receiving slot 1210.
The latch mechanism 6 comprises a pull tape 61 formed on a rear end thereof, an actuator 63 formed on a front end thereof, and a connecting portion 62 extending between the pull tape 61 and the actuator 63. The latch mechanism 6 is mounted on the housing 1, and the pull tape 61 extends beyond a rear end of the housing 1. The connecting portion 62 comprises a horizontal main portion 620, a limiting portion 624 located behind the main portion 620 and connected with the pull tape 61, a resisting portion 621 extending forwards and bent downwards from the main portion 620. The actuator 63 is structured in a curved shape and extending forwards from the resisting portion 621. An opening 6201 is defined on the main portion 620, and a block 6202 is defined on a front end of the opening 6201 and extending downwards. The main portion 620 is accommodated in the receiving slot 1210, and the resisting portion 621 is received in the extension slot 1211, the actuator 63 is disposed in the fixing slot 1212 and having a free end 631 coplanar with the first surface 11. The protrusion 1214 is inserted into the opening 6201, and the protrusion 1214 is capable of sliding in the opening 6201 along the front-to-back direction, the block 6202 is extending into the indentation 1216.
A spring 8 is received in the indentation 1216, with a front end thereof attached to the block 6202 of the latch mechanism 6, and a rear end attached to a back wall of the indentation 1216. As exerting a pulling force to the pull tape 61, the block 6202 in the opening 6201 is compressing the spring 8 moving rearwards. As releasing the pull tape 61, the spring 8 can promote the latch mechanism 6 in an original position by a restoring force of the spring 8.
The shielding member 5 comprises a top wall 51, a pair of lateral walls 52 extending downwards from both sides of the top wall 51, and a rear wall 53 extending downwards from a back end of the top wall 51. A pair of screw holes 1217 is defined on the second surface 12 of the housing 1. A pair of fixing holes 54 is defined on the top wall 51 and aligning with the corresponding screw holes 1217, a pair of screw pins 9 are inserted into the fixing holes 54 and the screw holes 1217, thus the shielding member 5 is fastened to the housing 1.
