technical field

The utility model relates to an electrical device, in particular to an electrical connector and an illuminating module with the electrical connector.

Background technique

FIG. 1 is an exploded schematic view of a conventional lighting module. It must be noted here that, for convenience of description, the illuminating device in FIG. 1 is shown in a cross-sectional manner. As shown in FIG. 1 , the conventional lighting module M1 includes an illuminating device 100 and an electrical connector 100'. The conventional lighting device 100 includes a reflector 110 , a lamp 120 , a first conductive contact 130 and a second conductive contact 140 . The reflector 110 has an opening 112 and a base portion 114 corresponding to the opening 112 . The bulb 120 is fixed on the base 114 and at least partially disposed within the reflector 110 . The bulb 120 has a first outer electrode 122 and a second outer electrode 124 opposite to each other. The first external electrode 122 is adjacent to the opening 112 , and the second external electrode 124 is disposed on the base 114 .

The first conductive contact 130 is disposed on the right side of the reflector 110 and outside the reflector 110 , and the first conductive contact 130 is adjacent to the opening 112 . The first external electrode 122 is electrically connected to the first conductive contact 130 through a wire 150 passing through the interior of the reflector 110 . The second conductive contact 140 has the same structure as the first conductive contact 130 , and is disposed on the left side of the reflector 110 outside the reflector 110 , and the second conductive contact 140 is adjacent to the opening 112 . The second external electrode 124 is electrically connected to the second conductive contact 140 through a wire 160 passing through the exterior of the reflector 110 .

The electrical connector 100' includes an external plug 110', a first internal conductive terminal 120' and a second internal conductive terminal 130'. The first internal conductive joint 120' is electrically connected to the external plug 110' through a wire 140', and the second internal conductive joint 130' is electrically connected to the external plug 110' through a wire 150'. In addition, the first internal conductive joint 120' is socketed on the first conductive contact 130, and the second internal conductive joint 130' is socketed on the second conductive contact 140.

When the user wants to activate the lighting device 100 to light the bulb 120, the user must insert the external plug 110' of the electrical connector 100' into a DC power supply (not shown). However, since the first conductive contact 130 representing the positive pole and the second conductive contact 140 representing the negative pole have the same shape and size, and the first internal conductive joint 120 ′ representing the positive pole is the same as the second internal conductive joint 130 representing the negative pole. ' have the same shape and size, so in the process of assembling the lighting module M1, the assembler may mistakenly insert the first internal conductive connector 120' on the second conductive contact 140 and mistakenly connect the second internal conductive connector 130 'sleeved on the first conductive contact 130. Therefore, when the user activates the lighting device 100 of the incorrectly assembled lighting module M1, the light bulb 120 of the lighting device 100 will burn out immediately. Based on the above, it is indeed necessary to improve the existing lighting module M1.
