  • Fig. 12 is a partially enlarged view of a second embodiment of the present invention, namely a partially enlarged view of between the electronic module 700, 700'and the module base 400.
  • the electronic module 700, 700' includes a casing 710 and a fastening implement 720 connected to the casing 710.
  • the fastening implement 720 has at least one elastic locking element 730, and the elastic locking element 730 is provided for engagement with the clasping member 104.
  • the module base 400 is disposed inside the housing body 102, and a first plate 410 is protrudingly disposed on the module base 400. According to the embodiment shown in Fig. 12 , there are preferably two clasping members 104, respectively disposed at two sides of the module base 400 of the housing body 102.
  • the module base 400 further includes at least one power-and-signal socket 430.

  • the pivoting portion 734 and the fastening implement 700 can either be integrally formed or be assembled and fixed together by screws (not illustrated) and etc.
  • the elastic locking element 730 can be integrally formed with or assembled to the casing 710 of the electronic module 700, 700' respectively.
  • An end of the press portion 732 is disposed away from the casing 710.
  • the hook portion 736 is disposed corresponding to the clasping portion 104 and provided for engaging the same.
  • a length from the press portion 732 to the pivoting portion 734 is greater than a length from the hook portion 736 to the pivoting portion 734. Therefore, when pressing the press portion 732, the press portion 732 rotates around the pivoting portion 734, and thus the hook portion 736 is moved toward a direction away from the second plate 740. Consequently, the hook portion 736 is detached from the clasping member 104, so as to make the electronic module 700, 700' disassembled from the module base 400. Similarly, when assembling the electronic module 700, 700' on the module base 400, the operation is alike.
  • the appearances, levels, sizes, and kinds of the power-and-signal socket 430 and the power-and-signal plug 780 vary from country to country, and a repetitive description thereof is omitted herein.
  • the module base 400 further includes a third plate 420.
  • a top end of the third plate 420 contacts against an inner surface of the housing body 102, and a height of the third plate 420 is preferably greater than a height of the first plate 410.
  • the height of the third plate 420 can be equal to the height of the first plate 410.
  • the housing body 102 further includes an inner recess 108 contacting against the third plate 420 of the module base 400, and thereby moisture is not easy to get into the inside of the housing body 102.
  • a wall thickness T of the first plate 410 connected to a surface of the module base 400 is thicker than a wall thickness t of the first plate 410 away from the surface of the base 400.
  • a wall thickness D of the second plate 740 connected to a surface of the fastening implement 720 is thicker than a thickness d of the second plate 740 away from the surface of the fastening implement 720. Therefore, when assembling the second plate 740 toward the first plate 410, assembling is easily done for the reason that the thinner wall thicknesses t and d of the first and second plates 410 and 740 produce a guiding effect therebetween.
  • a lateral side of the hook portion 736 of the elastic locking element 730 has a chamfer angle (not labelled in the drawings), and, a lateral side of the clasping member 104 corresponding to the above-mentioned chamfer angle also has a chamfer angle (not labelled in the drawings). Therefore, it only requires an external force to engage the hook portion 736 with the clasping member 104. More specifically, to assemble the electronic module 700, 700' to the module base 400, a repairman or a user only needs to make the second plate 740 of the fastening implement 720 be in alignment with and then assembled to the first plate 410 of the module base 400, and then the elastic locking element 730 can engage with the clasping member 104.
  • waterproof designs such as the close contact between the housing body 102 and the third plate 420, the close contact and engagement between the first plate 410 and the second plate 740, and a rubber piece 750 disposed between the power-and-signal plug 780 and the power-and-signal socket 140. As shown in Figs.
  • the rubber piece 750 can prevent water from entering into or outside the power-and-signal plug 780 and the power-and-signal socket 430, prevent the moisture from entering into the electronic module 700, 700' along an inner surface of the second plate 740, and protect the power-and-signal plug 430 from deformation or damage by an external force, thereby prolonging life spans of the power-and-signal socket 430, the power-and-signal plug 780, and other electronic components.
