Detailed Description

The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. 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 to 12, a quick-connect plug having a connection terminal, comprising:

a plug shell 1, on which a cable inlet and a cable outlet 2 are arranged;

a plug 3 including a plug 3 body and a conductive crimp 5 formed on the plug 3 body; the plug pin 3 body is at least partially positioned outside the plug housing 1, and the conductive crimping part 5 of the plug pin 3 body extends into the plug housing 1;

the push-type wiring terminal comprises a terminal shell 6, an elastic clamping piece 7 arranged in the terminal shell 6 and an operating piece 8 acting on the elastic clamping piece 7, wherein the elastic clamping piece 7 is opposite to the bolt 3 body and is provided with an insertion gap 9;

the cable 10 enters the plug housing 1 through the cable inlet and outlet 2 and extends into the insertion gap 9, and the operating member 8 is controlled such that the elastic clip 7, the cable 10 and the conductive crimp 5 are in contact and form an electrical connection.

The above is a basic scheme of the present invention, which combines the push-on terminal with the plug to form a new plug structure with a specific structure, so that the plug has the function of fast connecting and disconnecting the cable 10. In a specific practical operation process, the dismounting operation time of more than 30 seconds in the original bolt fixing mode can be shortened to be within 10 seconds, so that the dismounting efficiency of the cable 10 is greatly improved.

The basic technical scheme in the invention is further provided as follows: the operating piece 8 is sequentially provided with an upper picking end 11, a connecting end 12 and a pressing end 13 from front to back, the upper picking end 11 extends out of the terminal shell 6, the connecting end 12 is rotationally connected with the terminal shell 6, and the pressing end 13 can extend into the terminal shell 6 and form contact connection with the elastic clamping piece 7.

As is possible from the above arrangement, the operating element 8 therein preferably employs a lever-type operating mechanism. When the cable 10 needs to be plugged in and pulled out, a user lifts the upper picking end 11 of the operating member 8 upwards to enable the whole operating member 8 to rotate by taking the connecting end 12 as a rotation center, so that the pressing end 13 at the opposite position of the upper picking end 11 moves downwards, the pressing end 13 transmits force to the elastic clamping piece 7 in the downward moving process, the elastic clamping piece 7 deforms to vacate the plug-in gap 9, at the moment, the cable 10 can be directly and easily plugged in or the original fixed cable 10 can be released and taken out, finally, the user rotates the reset operating member 8 again, and the elastic clamping piece 7 is restored to an initial position state under the action of own elastic force, so that the elastic clamping piece 7, the cable 10 and the conductive crimping part 5 are clamped together to form electric connection.

Regarding the structure and the mating relationship between the connection end 12 and the terminal housing 6 are: the two sides of the connecting end 12 are convexly provided with rotating protruding points 30, the terminal shell 6 is provided with rotating holes 31, and the rotating protruding points 30 are clamped into the rotating holes 31.

In the present invention, the preferred form of construction of the resilient clip 7 itself is: the whole body of the device is in a rotary shape, and comprises a supporting part 14 positioned below, a driving deformation part 15 positioned above and connected with the supporting part 14, and a wire insertion part 16 connected with the front end of the driving deformation part 15; more preferably, the supporting part 14, the driving deformation part 15 and the plugging part are connected end to end in sequence and are integrally formed. Wherein, in order that the operating piece 8 can be abutted against the driving deformation part 15 and force the driving deformation part 15 to deform; a deformation gap 17 is formed between the supporting portion 14 and the driving deformation portion 15, the wire insertion portion 16 is provided with a connection opening 18 for the cable 10 to enter and exit, the cable 10 can enter and exit the elastic clamping piece 7 through the connection opening 18, and the function of releasing or clamping the cable 10 is achieved through the action of the operating member 8 on the driving deformation portion 15.

Meanwhile, in the operation process, in order to enable the elastic clamping piece 7 not to generate unnecessary displacement when being stressed, so as to ensure relatively stable working conditions, the adopted mode is as follows: the supporting part 14 is abutted against the conductive crimping part 5, so that an effective limiting and supporting effect is provided for the supporting part 14 through the conductive crimping part 5, and further, the supporting part 14 can be always kept in a relatively stable state when the driving deformation part 15 is stressed, so that the whole elastic clamping piece 7 is ensured to be normally used.

The front end of the conductive compression joint part 5 passes through the connection opening 18, but the conductive compression joint part 5 and the supporting part 14 of the elastic clamping piece 7 are affected by external force in the use process, if the limit is not applied, the related parts are easy to incline and separate after being stressed, and the whole function cannot be normally used. In order to prevent the defects, the invention ensures that the conductive crimping part 5 and the supporting part 14 of the elastic clamping piece 7 are not separated from the respective working positions in the use process, and adopts the following modes: the end of the conductive compression joint part 5 is tilted upwards to form an anti-falling flange 19, the anti-falling flange 19 passes through the connecting opening 18 from back to front, and the anti-falling flange 19 can be abutted with the supporting part 14 to form a limiting anti-falling fit.

More specific arrangement concerning the wire insertion portion 16 of the elastic clip 7 is: the connecting opening 18 is provided with a clamping part 21, the clamping part 21 is positioned below the conductive compression joint part 5, and the clamping part 21 is punched by the plug wire part 16. In the processing process, the connecting opening 18 and the clamping part 21 are formed on the wire inserting part 16, so that the connecting opening 18 is directly punched and the punched waste is bent to directly form the clamping part 21, the clamping part 21 and the conductive crimping part 5 are integrally formed in a single process step, the production efficiency is higher, the overall strength is better, and the material utilization rate is extremely high.

Preferably, the front end of the clamping portion 21 is bent downward to form an arc-shaped guiding portion 35, so as to reduce interference when the cable 10 is inserted, and enable the cable 10 to be more smoothly inserted.

Because the invention uses the pressing type wiring terminal in the plug for the first time, in order to realize the installation and the use of the pressing type wiring terminal, specific adaptive modification needs to be made on the original plug shell 1, and the preferable mode is as follows: the plug housing 1 is internally provided with a bracket 22 in a protruding manner, the terminal housing 6 is mounted on the bracket 22, and a mounting gap 23 is formed between the terminal housing 6 and the bracket 22. First, by providing the bracket 22, the fixing structure (e.g., the connection hole) of the terminal housing 6 can be better formed, so that the plug housing 1 and the terminal housing 6 can be connected together more stably and reliably. On the other hand, the formation of the mounting gap 23 can better accommodate and mount the components such as the elastic clip 7, the conductive crimp portion 5, and the like, and the terminal housing 6 can play an effective protective role after mounting.

Another understanding of the above-described embodiments is that the bracket 22 can be considered as another part of the terminal base, which forms a complete housing after being assembled with the terminal housing 6 for easy installation, later maintenance, disassembly and use.

The front end of the bracket 22 is further provided with a plurality of cable access ports 32 corresponding to the bolts 3 one by one, so as to ensure that the cable 10 (conductive copper wire) is inserted once.

According to different specifications of different countries, the shapes of the independent bolts 3 in the same plug are different, if the independent bolts 3 are not limited, the bolts 3 are easy to shake in the use process, the bolts 3 and wiring are seriously separated, and then the problem of circuit failure is caused. In order to solve the above-mentioned drawbacks, the support 22 is extended with a plurality of bars 33, positioning slots 34 are formed between adjacent bars 33, and the body of the latch 3 is at least partially inserted into the positioning slots 34. Through the arrangement of the bolt 3 body and the positioning groove 34, the bolt 3 body has a more stable position form relative to the plug shell 1 in the installation and use processes, and the normal reliability in use is further ensured.

In some embodiments of the present invention, the elastic clamping piece 7 is made of high-elastic stainless steel, so that a screw connection structure of the connection part of the bolt 3 and the cable 10 is omitted, the cost is greatly reduced, and the social benefits of energy conservation and emission reduction can be improved.

In this embodiment, the front end of the supporting portion 14 at least partially passes through the connecting opening 18 from the back to the front, and is connected in series with the latch 3 and the elastic clip 7, so that the two maintain a more stable mutual position state.

The specific structure and connection relation of the plug housing 1 are preferably: the upper end of the bottom shell 28 is provided with a convex rib 36, the lower end of the upper shell 29 is provided with a caulking groove 37, and the convex rib 36 is clamped into the caulking groove 37 to realize pre-assembly. Furthermore, the bottom shell 28 is fixedly connected with the upper shell 29 through a buckle 38.

In the invention, each conductive crimping part 5 is arranged straight along the horizontal direction, so that the exposed size of the bolt 3 is ensured to meet the standard requirement, and the cable 10 is ensured to be inserted in place once.

The situation that the cable 10 is pulled in the use of plug can not appear, and push type binding post compares with bolt fixed binding post, and is relatively less in the locking force to cable 10, consequently the condition that cable 10 misplaced, loosen with push type binding post appears easily under the pulling force effect and then leads to holistic circuit to be unable to switch on, and the function takes place to become invalid.

In order to avoid the possible drawbacks as described above, the present embodiment provides a solution as follows: the plug housing 1 is also provided with an anti-drop door assembly 24 which acts on the cable 10. For example, the specific structure of the anti-drop door assembly 24 may be: the cable connector comprises door plate subunits symmetrically arranged at two sides of a cable inlet and outlet 2, wherein each door plate subunit comprises a door plate base 25 (so as to be convenient to connect and install with a plug housing 1) and an anti-falling part 26, the door plate base 25 is installed in the plug housing 1, and the anti-falling part 26 is obliquely arranged inwards by the door plate base 25. After the cable 10 is connected, the interference fit formed by the direct contact between the outer peripheral wall of the cable 10 and the anti-falling door assembly 24 can play a role in effectively clamping the cable 10 so as to prevent the cable 10 from easily falling off.

Preferably, the anti-falling door assembly 24 has a plurality of contact ribs 27, and the contact ribs 27 can abut against the cable 10 and form an interference fit. Through the setting of contact muscle 27, the frictional force when can increasing the contact to play better spacing, anticreep effect.

In the further arrangement of the contact rib 27, the contact rib 27 is gradually biased towards the cable inlet and outlet 2 from the inside to the two sides, so that the contact position between the contact rib 27 and the cable 10 during insertion and extraction is specially limited, and the effect of easy insertion and difficult extraction is achieved. More specifically, the hardness of the contact rib 27 near the cable inlet and outlet 2 is smaller than that of the contact rib 27 far from the cable inlet and outlet 2. Can further reduce the resistance during insertion and improve the difficulty of extraction.

In the present invention, the specific structure of the plug housing 1 is as follows: a bottom shell 28 and an upper shell 29 are included to facilitate assembly. The use process is as follows: when the upper shell 29 is detached from the bottom shell 28, the upper picking end 11 can be turned upwards around the connecting end 12; when the upper case 29 is closed with respect to the bottom case 28, the upper case 29 can abut against the upper picking end 11 to restrict the upper picking end 11 from being turned upward.

The technical scheme is further provided as follows: the anti-drop door assembly 24 is made of soft materials, such as silica gel, plastic, etc., has good elasticity, can play a better self-adaptive clamping effect when being matched with the cable 10, and can not cause damage such as scratch to the cable 10 so as to play a role in protecting the cable 10.

In the invention, the operating member 8 has a certain dimension length, and when the plug housing 1 is completely assembled, even if the operating member 8 is overturned by a certain external force (tiny distance change), the operating member 8 can abut against the upper end of the plug housing 1 to limit the operating member 8 to continue rotating, so as to ensure that each component is not affected, and further ensure that the elastic clamping piece 7, the cable 10 and the conductive crimping part 5 are always in a reliable and stable connection state.

The invention provides a quick-connect plug with a wiring terminal, which comprises the following operation steps of: 1) Opening the plug housing 1 so that the internal structure of the plug is exposed; 2) The upper picking end 11 acts on the operating piece 8, so that the whole operating piece 8 turns upwards by taking the connecting end 12 as a rotation center; 3) When the operating piece 8 is turned in place, the pressing end 13 of the operating piece extends into the terminal shell 6 and is abutted with the elastic clamping piece 7, so that the elastic clamping piece 7 is forced to deform to release the insertion gap 9; 4) The external cable 10 is connected into the plug housing 1 through the cable inlet and outlet 2;

5) The cable 10 is sequentially connected into the insertion gap 9 of the corresponding bolt 3, and mutual alignment of the elastic clamping piece 7, the cable 10 and the conductive crimping part 5 is ensured; 6) The upper picking end 11 of the operating piece 8 is operated reversely, so that the whole operating piece 8 turns downwards by taking the connecting end 12 as a rotation center; 7) When the operation piece 8 is reset in place, the pressing end 13 of the operation piece leaves the elastic clamping piece 7, and the elastic clamping piece 7 also automatically resets under the self elastic acting force, so that the elastic clamping piece 7, the cable 10 and the conductive crimping part 5 are mutually clamped together to realize electric connection; 8) The anti-drop door assembly 24 acts on the peripheral side of the cable 10 to play a limiting anti-drop effect; 9) The plug housing 1 is completely assembled, and the plug can be normally used.

The foregoing description is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and any simple modification, variation and equivalent structural changes of the above embodiment according to the technical matter of the present invention still fall within the scope of the technical solution of the present invention.
