Embodiment
The present invention is about a kind of power connector, and it is applicable to electronic installations such as power-supply adapter, power supply unit, transformer.The utilization of this kind power connector is independent connects the terminal incoming call and connects power connector and the electronic installation that is suitable for, and the various shortcoming with the connection lead structure that improves existing power connector reduces the underproof probability of cost of manufacture and product simultaneously.Following examples will cooperate power connector of the present invention to further describe technology of the present invention with power-supply adapter, however technology of the present invention be not limited thereto, other can be applicable to technology of the present invention or the design also can incorporate reference into.
See also Fig. 3, it is the schematic diagram of first preferred embodiment of power connector of the present invention.As shown in Figure 3, wherein, power connector of the present invention mainly comprises insulating body 301, connects terminal 302, clamping element 303 and Connection Element 304.Wherein, the front of insulating body 301 is provided with port 3011 and aperture (not icon), with ccontaining connect terminal 302 and make connect terminal 302 and protrude from outside the aperture, and protrude from connecting terminal 302 and can directly be installed in the part hole 3031 of clamping element 303 and be fixed in wherein outside the aperture, in addition, make Connection Element 304 be held on other hole 3031, and weld on 30 the surface in clamping element 303 back to power connector, be fixed in simultaneously on this clamping element 303 with Connection Element 304 will connect terminal 302, and make and connect terminal 302 and be electrically connected with Connection Element 304, in addition, the other end of Connection Element 304 is connected on the circuit board 31 of electronic installation inside.
Significantly, because the terminal that connects that the technology of the present invention is researched and developed does not need and guide-joining plate or conducting pin riveted, but utilize clamping element as veil, face on another surface of power connector in the non-of clamping element, make in the mode of welding and to connect terminal and be fixed in clamping element with Connection Element and be electrically connected mutually, therefore, can't have influence on the structure of the insulating body of power connector because of welding process.In addition, the present invention also utilizes power line as Connection Element, therefore, does not also just have the wideless problem of the power connector scope of application and takes place, and has solved not only that power-supply adapter is connected inconvenient all puzzlements in the conventional art with electronic installation.Simultaneously, when power connector is assembled on the electronic installation, clamping element also can further be used for intercepting issuable impedance disturbances between power connector and the electronic installation, avoid electronic installation to be directly conducted to power connector, and influence the temperature of power connector because of the heat that running is produced.
Certainly, clamping element of the present invention is not limited to circuit board shown in Figure 3, see also Fig. 4, it is the schematic diagram of second embodiment of power connector of the present invention, as shown in Figure 4, and wherein, clamping element is connected in advance with Connection Element 405, and make Connection Element 405 be placed in the clamp ring 404 of clamping element and be fixed up, conducting terminal 402 then is that installing is gone in the port 403 of power connector 40, allows clamping element and conducting terminal 402 rivet mutually afterwards again.Thus, just can be by clamp ring 404 designs of this clamping element and the height that is had, Connection Element 405 stable forming with conducting terminal 402 are electrically connected, simultaneously can under the situation of the structure of the insulating body 401 that does not influence power connector 40, produce required power connector again.
In embodiments of the invention, the material that connects terminal is a metal material, and it is solid bar-shaped to be metal, also indefinite of the shape of clamping element, size, structure and method of clamping in addition, certainly the void shape of the clamping element shown in Fig. 3 also can change with actual needs, can be subjected to clamping element fixing as long as can guarantee to connect terminal.
In sum, power connector utilization of the present invention is independent connects terminal and finishes by power connector and be assembled on the electronic installation, with existing power connector by comparison, the guide-joining plate or the demand of conducting pin have not only been lacked, but also can utilize clamping element to extend to rivet and the distance of welding position, reduce riveted joint and welding step to the insulating body of power connector the influence that may cause, simultaneously, also can further intercept issuable impedance disturbances between power connector and the electronic installation by Connection Element, further avoid electronic installation can directly reach on the power connector, and influence the temperature of power connector because of the heat that running is produced.Further, the embodiment according to conception of the present invention developed out also can fix and protect Connection Element, even also can increase the area that can connect up on the printed circuit board (PCB), to adapt to the trend of electronic installation downsizing.
Above execution mode only is explanation the present invention's usefulness, is not in order to restriction the present invention.The various modifications that all those skilled in the art are done according to the present invention change with equivalence, all should belong within the scope of patent protection that claims of the present invention define.
