1. Technical Field
The present disclosure relates generally to connectors in electrical equipment, and more particularly to a connector using in an electronic device for mechanically connecting two or more pieces together.
2. Description of Related Art
Currently, many electronic devices have a small volume and are lightweight. Connectors used in these electronic devices are also miniaturized in order that they can conveniently fit inside the electronic devices.
A typical connector defines a plurality of apertures therein. The precision requirements of the positions of the apertures are so high that CNC (computer numerical control) machines are needed during manufacturing of the connector. However, CNC processing is complex and difficult, and the yield of the manufactured connectors is relatively low.
One method of reducing the above-described processing difficulties is to divide the connector into two parts. Each part has a more simple structure compared with the whole connector. The two parts are then engaged with each other by screws. However, the relative positions of the apertures in the two parts may not meet the necessary precision requirements when the screws are engaged in the two parts. In addition, the process of carrying out the screw engagement is troublesome.
What is needed, therefore, is an improved connector which can overcome the above-mentioned limitations.
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, like reference numerals designate corresponding parts throughout the views.

The main body 10 comprises a central plate 11, a first extension plate 12 perpendicularly extending from a lateral side of the central plate 11, and a second extension plate 13 extending from an opposite lateral side of the central plate 11. The central plate 11 has a substantially rectangular shape. The first and second extension plates 12, 13 extend from two long lateral sides of the central plate 11. The first and second extension plates 12, 13 are perpendicular to the central plate 11, and extend from the central plate 11 in substantially opposite directions. In particular, the first extension plate 12 extends down from the central plate 11, and the second extension plate 13 extends up from the central plate 11.
Two riveting holes 110 are defined in a substantially central portion of the central plate 11. The riveting holes 110 are through holes that extend through bottom and top surfaces of the central plate 11. A line extending through centers of the riveting holes 110 is perpendicular to the long lateral sides of the central plate 11. Each riveting hole 110 has an isosceles trapezoidal cross section. The dimension (diameter) of the riveting hole 110 increases gradually along a direction from the bottom surface to the top surface of the central plate 11. A low-profile protrusion 111 is formed on the top surface of an end portion of the central plate 11. This end of the central plate 11 is stepped, and the protrusion 111 has a rectangular shape and is correspondingly stepped. Three auxiliary holes 112 are defined in the end of the central plate 11 and near three sides of the protrusion 111 respectively, for extension of screws (not shown). The protrusion 111 and the auxiliary holes 112 cooperate to form a reinforcing structure 14. The reinforcing structure 14 is used for engaging with other elements for increasing an intensity (strength) of the central plate 11. A plurality of assembly holes 113 are defined in the central plate 11. The assembly holes 113 are round through holes. The assembly holes 113 are used for connecting another component (not shown) to the connector 100. A plurality of positioning holes 114 are defined in the central plate 11. The positioning holes 114 are elliptic through holes. The positioning holes 114 are used for pre-positioning another component (not shown) relative to the connector 100.
An engaging hole 121 is defined in one end of the first extension plate 12. The engaging hole 121 is a round through hole. The engaging hole 121 is larger than the assembly holes 113 and the positioning holes 114. The engaging hole 121 is used for connecting another component (not shown) to the connector 100. An opposite end of the first extension plate 12 has a sloped edge. A height of the first extension plate 12 at the sloped edge decreases gradually from an inner end of the sloped edge to an outer end of the sloped edge. The second extension plate 13 has a rectangular shape. The second extension plate 13 extends from an opposite lateral side of the central plate 11 to the first extension plate 12, and extends from the central plate 11 in a direction opposite to the direction in which the first extension plate 12 extends from the central plate 11. The purpose is to assist the assembly of other elements to the connector 100.
The block 20 has a T-shaped cross section. The block 20 comprises a first securing plate 21, and a second securing plate 22 extending upwardly from the first securing plate 21. The first securing plate 21 has a larger dimension compared with the second securing plate 22. Also referring to

In summary, the connector 100 comprising the separate main body 10 and block 20 is easy to process compared with a similar connector that is constructed as a single piece. The main body 10 and the block 20 are engaged with each other by the punching or riveting process to meet the precision requirements of the positions of the relevant holes such as the securing holes 211, the assembly holes 113 and the positioning holes 114. The punching or riveting together of the main body 10 and the block 20 is also simpler than a conventional screwed engagement.
It is believed that the present embodiments and their advantages will be understood from the foregoing description, and it will be apparent that various changes may be made thereto without departing from the spirit and scope of the disclosure or sacrificing all of its material advantages, the examples hereinbefore described merely being preferred or exemplary embodiments of the disclosure.
