DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
Referring to FIGS. 1-4, an anti-loosening electric connector mounting structure in accordance with the present invention is shown. The anti-loosening electric connector mounting structure comprises a housing 1, one or a plurality of electric connectors 2, and a plurality of retainers 3.
The housing 1 is a frame case for an electronic or electrical apparatus, having mounted therein a circuit board 11. Further, the housing 1 comprises a plurality of electric connector mounting slots 10 located in the peripheral wall thereof for the mounting of the electric connectors 2. After installation of the electric connectors 2 in the respective electric connector mounting slots 10, the electric connectors 2 are respectively electrically connected to the circuit board 11 in the housing 1 by respective electrical wires (not shown) for signal and/or power transmission between the electric connectors 2 and the circuit board 11. Each electric connector 2 comprises two retaining arms 21 respectively suspended from two opposite lateral walls thereof and respectively terminating in a respective barbed hook portion 211, and a retaining space 20 defined between each lateral wall and the associating retaining arm 21.
The retainers 3 are a-shaped resilient wire rod members, each comprising a substantially C-shaped retainer body 31, two curved arm portions 311 respectively extended from two opposite ends of the C-shaped retainer body 31, a narrow access gap 310 defined between the two curved arm portions 311, and two finger tips 32 respectively outwardly extended from the curved arm portions 311 remote from the C-shaped retainer body 31 in reversed directions. Further, when the retainer 3 is extended out without pressure, the combined length between the distal ends of the two finger tips 32 is larger than the vertical height of the retaining arms 21 of the electric connectors 2 and the vertical height of the electric connector mounting slots 10 of the housing 1.
In installation, the electric connectors 2 are respectively inserted into the respective electric connector mounting slots 10 of the housing 1 in direction from the space inside the housing 1 toward the space outside the housing 1. When inserting one electric connector 2 into one respective electric connector mounting slot 10 of the housing 1 from the inside the housing 1 toward the outside thereof, the barbed hook portions 211 of the retaining arms 21 are squeezed inwards to reduce the respective retaining spaces 20 for passing through the respective electric connector mounting slot 10. After passed the electric connector mounting slot 10, the barbed hook portions 211 of the retaining arms 21 immediately return to their former shape subject to the effect of the elastic material property of the retaining arms 21, and thus, the barbed hook portions 211 are respectively hooked on the peripheral wall of the housing 1 around the electric connector mounting slot 10. At this time, insert two retainers 3 from the outside of the housing 1 into the respective retaining spaces 20 between the two opposite lateral walls of the electric connector 2 and the retaining arms 21 to squeeze the curved arm portions 311 of each retainer 3 in narrowing the respective narrow access gap 310 and to force the C-shaped retainer bodies 31 and curved arm portions 311 of the retainers 3 through the respective electric connector mounting slot 10. Thereafter, release the pressure from the retainers 3, enabling the retainers 3 to return the respective C-shaped retainer bodies 31 and curved arm portions 311 into their former shapes. At this time, the finger tips 32 of the retainers 3 are stopped at the peripheral wall of the housing 1 around the respective electric connector mounting slot 10, and the C-shaped retainer bodies 31 and curved arm portions 311 of the retainers 3 are engaged in the respective retaining spaces 20 to stop the retaining arms 21 of the electric connector 2 from being squeezed inwards, and thus, the electric connector 2 is locked up in the respective electric connector mounting slot 10 of the housing 1, preventing loosening, displacement or falling. When the housing 1 is being delivered, moved, or impacted, the positioning of the retainers 3 in the respective retaining spaces 20 keep the respective electric connectors 2 in positive engagement in the respective electric connector mounting slot 10, prohibiting the electric connectors 2 from falling out of the housing 1. Further, the procedure of the installation of the electric connector 2 in the housing 1 is quite simple and convenient.
Referring to FIGS. 5 and 6 and FIGS. 2 and 4 again, when wishing to remove each electric connector 2 from the respective electric connector mounting slot 10 of the housing 1, squeeze the finger tips 32 of the respective two retainers 3 to narrow the respective narrow access gaps 310 and to elastically deform the C-shaped retainer bodies 31 and curved arm portions 311 of the respective two retainers 3 for allowing removal of the respective retainers 3 out of the respective retaining spaces 20 of the electric connector 2. After removal of the two retainers 3 from the respective retaining spaces 20 of the electric connector 2 and the housing 1, squeeze the two retaining arms 21 of the electric connector 2 to narrow the respective retaining spaces 20 and then push the electric connector 2 inwardly toward the inside of the housing 1 to move the two retaining arms 21 and the respective barbed hook portions 211 inwardly out of the electric connector mounting slot 10, and thus, the electric connector 2 is dismounted from the housing 1. Thus, the procedure of dismounting the electric connector 2 from the housing 1 is quite simple.
It is to be understood that the above-described preferred embodiment of the present invention is simply for the purpose of illustration only but not intended for use to limit the scope and spirit of the present invention. As stated above, in the anti-loosening electric connector mounting structure, the housing 1 comprises a plurality of the electric connector mounting slots 10 for the mounting of the electric connectors 2. After insertion of the electric connectors 2 into the respective electric connector mounting slots 10 the barbed hook portions 211 of the retaining arms 21 of the electric connectors 2 are respectively hooked on the outer surface of the peripheral wall of the housing 1 around the respective electric connector mounting slots 10, and then the retainers 3 are respectively inserted into the respective retaining spaces 20 at two opposite lateral sides of the respective electric connectors 2 with the finger tips 32 of the respective retainers 3 protruded over the opposing top and bottom sides of the respective retaining arms 21 of the respective electric connectors 2 and stopped at the outer surface of the peripheral wall of the housing 1 around the respective electric connector mounting slots 10 to lock up the respective electric connectors 2 in the respective electric connector mounting slots 10 of the housing 1. By means of squeezing the finger tips 32 to elastically deform the respective retainers 3, the retainers 3 can easily be removed from the respective retaining spaces 20 of the respective electric connectors 2 to unlock the respective electric connectors 2, allowing squeezing of the retaining arms 21 and removal of the respective electric connectors 2 from the respective electric connector mounting slots 10 of the housing 1.
In conclusion, the invention provides an anti-loosening electric connector mounting structure, which comprises a housing having a plurality of electric connector mounting slots located in a peripheral wall thereof, a plurality of electric connectors respectively detachably mounted in the electric connector mounting slots, each electric connector having two retaining arms suspended from two opposite lateral walls thereof and a retaining space defined between each lateral wall and one respective retaining arm, and retainers respectively set in the retaining spaces to lock up the electric connectors in the respective electric connector mounting slots.
