Power supply connector assembly device

(a) Field of the Invention

The present invention relates to a power supply connector assembly device, and more particularly to a power supply connector having a structure including two insulating bodies.

(b) Description of the Prior Art

Referring to FIGS. 1 and 2 , which show a prior art power connector A, wherein a first conductive body A 2 and a second conductive body A 3 are disposed within a holding cavity A 4 of an insulating body A 1 , thereby enabling the power connector A to combine the first conductive body A 1 and the second conductive body A 3 into an integrated body. However, because of deformation in a contact portion A 6 between the first conductive body A 2 and the second conductive body A 6 when connecting the power connector A to a power plug A 5 , thus, a poor contact results with the power connector A after plugging and unplugging multiple times. Moreover, poor contact between the first conductive body A 2 and the second conductive body A 3 results in the power connector A being unable to achieve the objective of good electrical conductance.

Hence, the present invention herein discloses a new and improved configuration to resolve and surmount existent technical difficulties to eliminate the aforementioned shortcomings.

The present invention provides a power supply connector assembly device, wherein a power supply connector has a structural configuration that utilizes two insulating bodies, so that when contact portions of a first conductive terminal and a second conductive terminal make contact with uniformly distributed inner and outer contact portions of an electric plug, then the contact portions of the first conductive terminal and the second conductive terminal provide even support between the power supply connector and the electric plug, thereby achieving a good and stable electrical connection between the power supply connector and the electric plug.

Moreover, the joining portions C 8 of the rear insulating body C 4 that fit into the corresponding joining holes C 3 of the front insulating body C 1 fixedly combine the front insulating body C 1 and the rear insulating body C 4 to form an integrated body.

Furthermore, the first conductive terminal D 1 comprises holding slots D 2 that are used to hold the protruding connecting portion C 5 , solderable and conductive soldering portions D 3 and contact portions D 4 . The second conductive terminal D 5 comprises clasp portions D 6 corresponding to the embedding grooves C 6 , solderable and conductive soldering portions D 7 and contact portions D 8 . Furthermore, the signal terminal E comprises an inverted hook E 1 that can be used to embed and join, and solderable and conductive soldering portions E 2 and contact portions E 3 .

The covering case F comprises a holding space F 2 that is used to hold the conductive terminal D. When the insulating body C including the conductive terminal D is contained within the holding space F 2 , then the power supply connector B can be soldered to a printed-circuit board using soldering portions F 1 of the covering case F, the soldering portions D 3 of the first conductive terminal D 1 , the soldering portions D 7 of the second conductive terminal D 5 and the soldering portions E 2 of the signal terminal E, thereby achieving the objective of enabling a power connector A to achieve a stable connection and conducting of electric power.

Moreover, when the front insulating body C 1 is combined with the covering case F, the front insulating body C 1 is secured within the covering case F by means of check portions C 9 on side surfaces of the front insulating body C 1 , which prevent the front insulating body C 1 from sliding out.

Furthermore, when the rear insulating body C 4 and the covering case F are joined together, guide portions C 10 of the rear insulating body C 4 and check portions C 11 of the guide portions C 10 are able to fixedly combine together the rear insulating body C 4 and the covering case F to form an integrated body. When the rear insulating body C 4 and the covering case F are joined together, the rear insulating body C 4 is smoothly disposed within the covering case F by means of inclined surfaces C 12 of the guide portions C 10 , and the check portions C 11 of the guide portions C 10 prevent the rear insulating body C 4 from sliding out.

The first conductive terminal D 1 comprises the holding slots D 2 that enable the protruding portion C 5 to embed therein, and the solderable and conductive soldering portions D 3 and contact portions D 4 .

When the first conductive terminal D 1 and the second conductive terminal D 5 are embedded into and thereby combined with the front insulating body C 1 and the rear insulating body C 4 respectively, then the power supply connector B can be soldered to a printed-circuit board, thereby producing a good conductive contact between the first conductive terminal D 1 and the second conductive terminal D 5 .

Referring to FIG. 8 , when the power supply connector B makes contact with an electric plug G, then the first conductive terminal D 1 makes contact with outer layer conductive portions G 1 , the second conductive terminal D 5 makes contact with inner layer conductive portions G 2 and a connecting portion G 3 protruding from a center of the electric plug G is clamped within the signal terminal E, thereby embedding the power supply connector B within the electric plug G and achieving the objective of electric conductance and signal transmission.

After the contact portions D 4 of the first conductive terminal D 1 and the contact portions D 8 of the second conductive terminal D 5 joined within the insulating body C have made contact with the inner and outer layer conducting portions G 1 , G 2 of the electric plug G, then an electrical contact is made between the power supply connector B and the electric plug G, and a good contact is achieved between the first conductive terminal D 1 and the second conductive terminal D 5 without causing deformation in the conductive terminal D.
