1. Technical Field
The present disclosure relates to an electrical connector assembly.
2. Description of Related Art
An electrical connector assembly generally includes a male connector and a female connector connectable to the male connector. For the male connector with a rectangular connection portion and the female connector defining a rectangular recess to hold the connection portion, a great force is needed to insert the male connector into the female connector or disassemble the male connector from the female connector. The amount of force used by a person cannot be accurately controlled and may easily be too great and damage the connectors.
Many aspects of the present embodiments can be better understood with reference to the following drawings. The components in the drawings are not necessarily drawn to scale, the emphasis instead being placed upon clearly illustrating the principles of the present embodiments. Moreover, in the drawings, all the views are schematic, and like reference numerals designate corresponding parts throughout the several views.
The disclosure is illustrated by way of example and not by way of limitation in the figures of the accompanying drawings in which like references indicate similar elements. It should be noted that references to “an” or “one” embodiment in this disclosure are not necessarily to the same embodiment, and such references mean at least one.
Referring to
The male connector 30 includes a rectangular insulating housing 35 and a plurality of cables 34. The housing 35 defines a plurality of slots 331 extending through a front surface 33 to a back surface opposite to the front surface 33. A plurality of terminals 37 is embedded in the slots 331 and connected to the cables 34. An anti-mistake insertion tab 310 protrudes from a middle top 31 of the insulating housing 35. Two substantially semi-cylindrical protrusions 36 protrude from the top 31 of the housing 35, at two sides of the middle of the insulating housing 35. Each protrusion 36 includes an arc-shaped insertion surface 361 at a front surface of the protrusion 36, and an arc-shaped ejecting surface 362 at a rear surface of the protrusion 36 opposite to the insertion surface 361. Two blocks 320 protrude from left and right end surfaces 32 of the insulating housing 35, respectively. In another embodiment, the protrusions 36 can be triangular, and the insertion surface 361 and the ejecting surface 362 can be inclined surfaces.
The female connector 40 includes a rectangular insulating housing 45. The insulating housing 45 defines a recess 46 in a rear surface of the insulating housing 45. A plurality of terminals 44 is assembled in the recess 46. An anti-mistake insertion gap 410 communicating with the recess 46 is defined in a top 41 of the insulating housing 45, to engage with the tab 310 of the male connector 30. Two fastening holes 46 are defined in the top 41, at opposite sides of the insertion gap 410, respectively. An elastic tab 461 extends down from a sidewall bounding each fastening hole 46 adjacent to the rear surface of the insulating housing 45. Two isolating slots 462 (labeled in
Referring to
In disassembly, the protrusion 36 are operated to disengage from the fastening holes 46. The ejecting surfaces 362 resist against the elastic tabs 461, to deform the elastic tabs 461 and the top 41 up. Because of the elastic tabs 461 and the ejecting surfaces 362, the force acted on the male connector 30 increases gradually, thus the male connector 30 can be moved away from the recess 46 of the female connector 40 easily. The blocks 320 also disengage from the corresponding grooves 420.
It is to be understood, however, that even though numerous characteristics and advantages of the present disclosure have been set forth in the foregoing description, together with details of the structure and function of the disclosure, the disclosure is illustrative only, and changes may be made in details, especially in matters of shape, size, and arrangement of parts within the principles of the disclosure to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
