Description
Technical Field
The present invention relates to a wire connecting terminal, and more particularly, to an improved structure of a connector limiter for a wire connecting terminal.
Background
Devices for creating an electrical wiring connection for electronic and motor equipment are known in the art using metal components (or conductive components) and metal spring plates encased in an insulating housing (typically made of plastic material) to press or bond wires into terminals to form electrical connections (or to be mounted on an operating panel, electrical distribution box, etc.). For example, U.S. Pat. No. 3, 6689955B2 "CONNECTING DEVICE WITH A CONNECTION SPRING OPERATED BY A CAM", or U.S. Pat. No. 2003/0194918A1, taiwan 103206602 "switch terminal block structure", etc., provide exemplary embodiments.
One problem associated with conventional wire connection terminals in terms of operation and application is that when a wire is inserted into a housing and a wire connector, the wire will first press down a metal spring, and then the wire is snapped or clamped together with the wire connector by the elastic force of the metal spring to form an electrical connection. In order to avoid the situation that the bare metal end of the wire is inserted into the shell or the metal spring is deflected to scratch the shell and the clamping is unstable due to the large number of insertion operations and human negligence when the wire is inserted into the shell, the prior art discloses a structure of a wire connector combination limiter, and the problems can be improved. For example, DE202008015306U1, US2013/0143433A1 "CONNECTION TERMINAL", DE102012009286A1, EP1353407A1, and the like, provide viable embodiments.
In the conventional wire connector assembly limiter and metal spring, a tool (such as a screwdriver or the like) is used to press the metal spring to force the metal spring to bend during the assembly and disassembly operations, so as to release the state of the metal spring pressing or biting the wire. However, as known to those skilled in the art, because of the carelessness of personnel operation or the situation of increasing the force applied by the nature of the operators in order to truly release the state of pressing or biting the metal spring, the metal spring is often forced to be excessively bent, and the material of the metal spring is easily fatigued to influence the function of pressing or biting the wire under the condition of excessively bending and using the metal spring for a long time or frequently pressing down, which is not desirable.
Typically, these references show the art regarding the design of electrical connection terminals or wire connectors, metal spring and related combinations, which if redesigned consider the structural combination of wire connectors, metal spring to make its construction different from that of the conventional one, will change its usage form from that of the old one, and will substantially increase its application range. For example, the fixed structure or the combination relation of the wire connector and the metal spring sheet is changed under the condition that the miniaturization evolution and the design trend of the terminal device are met and the volume of the terminal device is not increased, so that the structure of the wire connector and the metal spring sheet is easy to manufacture and operate.
And, it is considered to provide a terminal device (or a connector) provided with a limiter and a limiting mechanism, and it is particularly considered and required to incorporate the limiter into the limiting mechanism for surely accommodating the movement path of the metal elastic piece and to provide the limiting mechanism with an action and a mechanism for preventing the metal elastic piece from being excessively bent during the operation by an external force. None of these problems are specifically taught or disclosed in the above references.

Detailed Description
The following description of the embodiments of the present invention will be made apparent, and it is intended, in view of the accompanying drawings, to provide a clear and complete description of the embodiments of the present invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Referring to fig. 1, an improved structure of a connector limiter for a wire connecting terminal of the present invention includes a combination of a limiter and a limiting mechanism, generally indicated by reference numerals 10 and 20, respectively. The limiter 10 and the limiting mechanism 20 may be assembled in a known insulating housing, combined with conductive brackets, electrical contacts and metal spring plates (this part is known in the art and is not shown), to form a push button switch device, electrical connection terminals or the like, providing the function of pivoting wiring circuits or leads from electronic or electromechanical devices. Basically, the limiter 10 defines at least one (internal) space, and the structure of the combined metal spring is selected to allow at least one wire to be inserted according to the application type or mode.
In the embodiment employed, the limiter 10 is formed from a relatively rigid or stiff material (e.g., iron, steel..etc.) to form a flat sheet blank, and the limiter 10 is formed from the flat sheet blank to form a rectangular frame structure as shown in fig. 1.
The limiter 10 is depicted as including a first edge 11, a second edge 12 connected to the first edge 11, a third edge 13 connected to the second edge 12, a fourth edge 14 connected to the third edge 13, and so on. And, the first side 11 is bent toward the third side 13 to form a first sub-side 16 (e.g., such that the first side 11 and the first sub-side 16 form an acute, right or obtuse included angle), thereby creating a first space 18.
The fourth side 14 is also shown bent in the direction of the second side 12 to extend to form a fifth side 15, the fifth side 15 and the first side 11 being in the same plane, and the fifth side 15 being bent in the direction of the third side 13 to extend to form a second minor side 17 (e.g. to form an acute, right or obtuse included angle between the fifth side 15 and the second minor side 17), creating a second space 19. The first secondary side 16 and the second secondary side 17 are parallel and have lengths respectively smaller than those of the second side 12 and the fourth side 14 (or the lengths of the first secondary side 16 and the second secondary side 17 are respectively greater than or equal to 1/2 of the lengths of the second side 12 and the fourth side 14), so that a first space 18 is formed and communicated with a second space 19. And, the first space 18 and the second space 19 can jointly or separately accommodate the combined metal spring, and allow the metal spring to form a swingable mode in the limiter 10 (or the first space 18 and the second space 19) so as to clamp the fixed wire.
In the known metal spring structure, the metal spring can form a bifurcation structure, and two legs respectively press two wires inserted into the limiter 10, so that in the adopted embodiment, at least the second side 12 and the first secondary side 16, the fourth side 14 and the second secondary side 17 of the limiter respectively assist in normalizing the movement paths of the two legs of the metal spring.
Fig. 1 also depicts the limiter 10 bent (vertically) over an extension 30 at the upper end of the third side 13. The extension 30 may selectively be in contact with other components of the switchgear or electrical coupling terminals to form an energized or non-contacted to form a de-energized effect.
In the preferred embodiment, the limiting mechanism 20 includes a combination zone 21 disposed at least on the second side 12, fourth side 14 of the limiter and a stop 22 disposed on the combination zone 21. The stop body 22 is a cylinder structure with a square cross section, and can be assembled and disassembled to transversely pass through the limiter 10 (or the first space 18 and the second space 19) in the drawing, and the assembling area 21 is used for standardizing the movement range or the bending angle of the metal elastic sheet so as to prevent the situation that the metal elastic sheet is excessively bent due to external force operation to cause material fatigue or damage.
The combined area 21 is also shown to have a hole structure on the second side 12 and fourth side 14 nearer to the third side 13, and the combined area 21 is configured at an oblique angle. Assuming that the combination area 21 is disposed at an angle inclined downward from the first side 11 or the fifth side 15 toward the third side 13 with reference to the reference axis X. After the combination area 21 is obliquely configured to combine the stop body 22, the metal spring is facilitated to be pressed against the plane part of the stop body 22 when the metal spring is pressed down and bent by personnel, so that the situation that the metal spring is excessively bent can be reduced, and meanwhile, the pressing fit between the metal spring and the stop body 22 is facilitated.
In a possible embodiment, the second and fourth sides 12, 14 are shown with a foot 12a, 14a protruding from a bottom end position or region of the limiter 10 and fingers 12b, 14b formed on the feet 12a, 14a (sides), the fingers 12b, 14b facilitating the combination and securement of the limiter 10 and metal spring (or conductive bracket, connector, etc.).
Referring to fig. 2, the third side 13 is shown with a mouth 13a formed therein, and the first secondary side 16 (and/or the second secondary side 17) is formed with a convex end 16a. The overall length of the first secondary side 16 and the protruding end 16a is shown to be greater than the length of the second secondary side 17, so that the protruding end 16a can enter or pass through the opening 13a, and the opening 13a can be used for limiting the load of the first secondary side 16 (and/or the second secondary side 17) to form a stable structure, so that the first secondary side 16 and the second secondary side 17 cannot deviate, and the metal spring sheet can not deviate or shake during operation, so that the function of really standardizing the movement path of the metal spring sheet is jointly established.
Fig. 2 or 3 disclose that the limiter first minor edge 16 extends to a position adjacent the third edge 13, creating a first space 18 that is completely enclosed in the periphery. The second secondary side 17 extends to a position adjacent to the third side 13, creating a second space 19 which is completely closed in its periphery. At least the second side 12 and the first secondary side 16 assist in defining the movement path of the metal dome, and the fourth side 14 and the second secondary side 17 assist in defining the movement path of the other metal dome.
Fig. 3 discloses a situation in which the length of the first secondary side 16 is equal to the length of the second secondary side 17. A modified embodiment is also shown, the limiting means 20 comprising a combination of at least the second side 12 and the fourth side 14, a combination 21, and a stop body 22 arranged on the combination 21. The stop body 22 is a protruding plate structure extending from the combination zone 21 in the direction (or transverse) towards the interior of the limiter 10 or the first and second spaces 18, 19.
Fig. 3 also shows the positions of the combination zone 21 and the stop body 22 on the corresponding second side 12, fourth side 14, the first secondary side 16, second secondary side 17 being formed with the combination zone 21 and the stop body 22 extending from its combination zone 21 towards the first space 18, second space 19, respectively, of a protruding sheet structure.
In the preferred embodiment, the second side 12, fourth side 14 and/or the first secondary side 16, the combined area 21 of the second secondary side 17 and the stop 22 are also disposed at an oblique angle as shown in FIG. 3. Assuming that the reference axis X is used as a reference in the drawing, the arrangement angle of the stopper 22 (and/or the combination area 21) is a pattern of being inclined downward from the first side 11 or the fifth side 15 toward the third side 13.
It can be appreciated that the inclined configuration of the stop body 22 is helpful for a person to press the metal spring against the plane portion of the stop body 22 when the person presses the metal spring to bend, so that the situation that the metal spring is excessively bent can be reduced, and the press fit between the metal spring and the stop body 22 is facilitated.
Fig. 3 also shows that the stop body 22 of the plate structure can be produced using a stamping operation. In one possible embodiment, the stop member 22 of the limiting mechanism 20 may be disposed directly on the second side 12, the fourth side 14, the first secondary side 16 and/or the second secondary side 17, or may be adhered to form the stop member 22 on the second side 12, the fourth side 14, the first secondary side 16 and/or the second secondary side 17.
Please refer to fig. 4, which is a derivative embodiment of fig. 1, fig. 5, which is a derivative embodiment of fig. 2, and fig. 6, which is a derivative embodiment of fig. 3. The structure that the limiter 10 forms a caulking groove 123 between the second side 12 (upper end position) and the third side 13 (upper end position) and a caulking groove 134 between the third side 13 and the fourth side 14 is shown, and the caulking grooves 123 and 134 are used for assisting the limiter 10 to combine and fix metal shrapnel. The positions of the side edge adjacent to the caulking groove 123 at the upper end of the second side 12 and the side edge adjacent to the caulking groove 134 at the upper end of the fourth side 14 are also disclosed in the figure, the structures of the finger parts 12b and 14b are respectively formed, and the finger parts 12b and 14b can be matched with the caulking grooves 123 and 134 to combine and fix the metal elastic sheet.
Fig. 6 also depicts that the second side 12 and fourth side 14 form a combined area 21 and stop body 22. The stop body 22 is a structure extending from the combination zone 21 towards the inside of the limiter 10 or the direction (or transverse direction) of the first and second spaces 18, 19 and the first and second secondary edges 16, 17 are formed with the combination zone 21.

Typically, the improved structure of the connector limiter of the wire connecting terminal has the following advantages compared with the old method under the conditions of conforming to the miniaturization design trend of the terminal device and not increasing the volume of the terminal device:
1. the limiter 10 combines the limiting mechanism 20 and related component structures, which have been redesigned. For example, the limiter 10 comprises a first side 11, a second side 12, a third side 13, a fourth side 14 and a fifth side 15, the first side 11 is bent to form a first secondary side 16, the fifth side 15 is bent to form a second secondary side 17, and a frame structure of the first space 18 and the second space 19 is established together to accommodate the standard metal spring, the limiting mechanism 20 comprises a combination area 21 formed at least on the second side 12, the fourth side 14 and/or the first secondary side 16 and the second secondary side 17, the combination area 21 combines a stop body 22 of a cylinder structure or a stop body 22 of a protruding sheet structure extending from the combination area 21 towards the inside of the limiter 10, and the like, which are obviously different from the prior art, and the fixing structure or the combination relation of the conventional electric connector and the metal spring is changed, so that the use and the operation state of the limiter are different from the old method.
2. Particularly, the design of the combined limiting mechanism 20 of the limiter 10 can standardize the movement range or bending angle of the metal spring sheet, obviously improve the situation that the metal spring sheet is excessively bent due to long-term or frequent external force operation to produce material fatigue or damage, influence the situation that the metal spring sheet presses or bites a wire and the like, not only provide the effects that the operation of personnel is simple and convenient and the manufacturing is easy, but also enable the situation that the conventional wire metal bare end is inserted into a shell or the metal spring sheet is deflected, the shell is scratched, the clamping is unstable and the like, and be minimized as much as possible.
3. The structure that the inclination angle of the stop body is 0 degree and is the same as or parallel to the first side, the third side or the fifth side can lead the sharp edge of the stop body to be correspondingly arranged on the path of the pressing motion of the metal spring plate, the damage of the metal spring plate is easy to be caused in the long-term and high-frequency operation process, and the structure matching effect is not ideal. Therefore, the stop body 22 of the combining area 21 is inclined, which is beneficial to the pressing of the metal spring plate against the plane part of the stop body 22 when the metal spring plate is pressed down and bent by personnel, so that the situation that the metal spring plate is excessively bent can be reduced, and the pressing fit between the metal spring plate and the stop body 22 is facilitated.
Therefore, the present invention provides an effective connector limiter structure for wire connection terminals, which has a space shape different from that of the prior art, and has the advantages incomparable with the prior art, and shows considerable progress, and fully meets the requirements of the invention patent.
In summary, the above embodiments and the accompanying drawings are only preferred embodiments of the present invention, and are not intended to limit the scope of the present invention, but any modifications, equivalent substitutions, improvements, etc. within the spirit and principle of the present invention should be included in the scope of the present invention.
