The present invention relates to a connector plug and connector assembly, and more particularly to a connector plug having plug contacts and a connector receptacle having receptacle contacts.
In the prior art, a connector assembly generally comprises a connector plug and a connector receptacle mated with the connector plug. A plurality of receptacle contacts are provided in the receptacle, and a plurality of plug contacts are provided in the plug. When the plug is inserted into the receptacle in a predetermined correct posture, the plug contacts electrically connect to the receptacle contacts. However, if the plug is inserted into the receptacle in an incorrect posture, as shown in
An object of the present invention is to provide a connector plug that can prevent a bottom of the plug from pressing and damaging receptacle contacts of a receptacle due to insertion misalignment. The disclosed connector plug has a housing and a plurality of end walls disposed on the housing. The plurality of end walls each include at least one block notch.
The invention will now be described by way of example with reference to the accompanying Figures, of which:
Exemplary embodiments of the present disclosure will be described hereinafter in detail with reference to the attached drawings, wherein the like reference numerals refer to the like elements. The present disclosure may, however, be embodied in many different forms and should not be construed as being limited to the embodiments set forth herein; rather, these embodiments are provided so that the present disclosure will be thorough and complete, and will fully convey the concept of the disclosure to those skilled in the art.
The connector assembly, as shown in
As shown in
The plurality of plug contacts (not shown) are disposed in the housing 110.
The two end walls 112 are provided at opposite end portions of the housing 110 in a length direction of the housing 110, and are both formed in a width direction of the housing 110 such that they extend orthogonal to the length direction of the housing 110. In an exemplary embodiment of the present invention, one side of each the two end walls 112 extends beyond the housing 110 in a width direction of the housing 110. The side of each end wall 112 that extends beyond the housing 110 extends beyond the same side of the housing 110. In another exemplary embodiment, shown in
In the exemplary embodiment of
The block notch 114 may be configured to have various shapes as long as the block notch 114 can be engaged or fitted with an upper edge of a side wall of a receptacle when the plug 100 slides on the upper edge of the side wall of the receptacle as shown in
In an exemplary embodiment, the block notch 114 comprises a block face 114a extending away from the housing 110 substantially in the width direction of the housing 110. The block face 114a may be formed by a bump protruding from one side of the end wall 112 in the width direction, and a bottom surface of the bump defines the block face 114a. The block notch 114 may be defined between the block face 114a and the one side of the end wall 112 in the width direction.
In an exemplary embodiment, as shown in
In another exemplary embodiment, as shown in
As shown in
In another embodiment, the plug 100 may be a plurality of shorter plugs 100.
As shown in
The plurality of receptacle contacts 220 are provided in the receptacle case 210, as shown in
As shown in
A plurality of recesses 214 are formed at positions of the side walls 212 of the connector receptacle 200 adjacent to end walls of the connector receptacle 200. In the exemplary embodiment of
A rectangle recess 216 is formed in an upper portion of one of the side walls 212 of the receptacle case 210. The rectangle recess 216 is optionally positioned in the center of the side wall 212, but may be positioned anywhere along the length of the side wall 212.
The assembly of the connector plug 100 and connector receptacle 200 will now be described with reference to
As shown in
The upward tapered shape of the upper outer edge 212a can facilitate the engagement of the upper edge of the side wall 212 with the block notch 114 during incorrect aslant insertion of the plug 100. In another embodiment, if the upper edge 212a of the side wall 212 has a thin thickness, the upper edge 212a of each of the side walls 212 may be not formed in the upward tapered shape.
During aslant insertion of the plug 100 into the receptacle 200, the recesses 214 provide passages through which the block notches 114 of the plug 100 passes while the plug 100 is rotated downward with respect to the upper edge of one side wall 212 of the receptacle 200, so as to prevent the block notch 114 from being engaged or snapped with the upper edge of the side wall 212.
In another orientation of an incorrect aslant insertion of the plug 100 into the receptacle 200, as shown in
In another orientation of an incorrect aslant insertion of the plug 100 into the receptacle 200, as shown in
In another orientation of an incorrect aslant insertion of the plug 100 into the receptacle 200, as shown in
As would be appreciated by one skilled in the art, the embodiments and orientations described above would equally apply if the plug 100 included a plurality of shorter plugs fitting into the one receptacle 200.
