With the development of the electronics industry, the use of terminal blocks has become more and more diverse. In addition to PCB board terminals, the most widely used ones are hardware terminals, nut terminals, spring terminals, and so on.

[0003] The connection methods of automobile terminals and wires are usually crimping and welding, which require the use of corresponding crimping equipment or welding equipment, and must be carried out in a specific processing site. When the wire is burned or damaged and needs to be replaced, the automobile terminal cannot be quickly removed from the wire, and the entire wire and automobile terminal need to be replaced, which not only wastes resources, but also can only be crimped with manual tools, which is time-consuming and labor-intensive, and it is difficult to ensure the stability of the connection between the terminal and the wire.

[0013] Beneficial effects:

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] (1) The utility model rotates the conductive member, and as the protrusion gradually moves away from the connection and fixing point between the pressing part and the clearance through hole, the resistance to the spring gradually decreases, and the elastic force applied to the protrusion gradually increases, so that the pressing part presses the wire in the wire-containing cavity, thereby achieving the effect of fixing the wire.

[0028] It is worth mentioning that the conductive member 2 is provided with a guide column 23 and inserted into the blind hole 12. The guide column 23 is provided with a fixing block 24 corresponding to the clearance groove 13 and inserted into the clearance groove 13. The conductive member 2 is rotated so that the fixing block 24 abuts against the side wall of the fixing groove 14, so that the conductive member 2 is connected and fixed to the cavity 11. The guide column 23 is used in conjunction with the blind hole 12, and the fixing block 24 connects and fixes the guide column 23 to the cavity 11.

[0029] It is worth mentioning that the snap-fit ​​method is set as a fixing block 24, which is connected by snap-fitting, so that the conductive member 2 is easy to separate or install from the terminal body 1, and it is easy to replace the damaged conductive member 2;

[0030] It is worth mentioning that the conductive member 2 is provided with a retaining ring 25, and the outer wall of the retaining ring 25 is provided with a plurality of anti-sliding blocks 251, and the inner wall of the line-containing cavity 21 is provided with a plurality of equally spaced through holes 26 with the dot as the axis, and the end face of the through hole 26 is provided with an avoidance through hole 27, and one end of the pressing portion 22 is connected and fixed to one end of the through hole 26, and the retaining ring 25 limits the depth of the conductive member 2 entering the cavity 11, and the anti-sliding block 251 increases the friction force, which is convenient for the staff to apply a rotational force to the conductive member 2, and the through hole 26 limits the range of motion of the protrusion 33, and the avoidance through hole 27 facilitates the conductive member 2 to leave the cavity 11, and the connection between one end of the pressing portion 22 and one end of the through hole 26 will be closer to the inner wall of the line-containing cavity 21, so that the resistance here is the largest;

[0031] It is worth mentioning that the inner wall of the cavity 11 is provided with a plurality of equally spaced avoidance grooves 15 with the dot as the axis, and limiting grooves 16 are provided on both sides of the avoidance groove 15. The avoidance groove 15 is provided with a notch 17. The avoidance groove 15 is provided with first countersunk holes 18 with equal intervals from top to bottom. The avoidance groove 15 provides a holding space for the top block 3, the limiting groove 16 limits the distance of the top block 3 extending or retracting, the notch 17 facilitates the extension and contraction of the protrusion 33, and the first countersunk hole 18 increases the holding space of the spring 4;

[0032] It is worth mentioning that the top block 3 is arranged in the avoidance groove 15, and the limit blocks 31 are arranged on both sides of the top block 3 and are arranged in the limit groove 16. The top block 3 is provided with second countersunk holes 32 with equal intervals from top to bottom, and the second countersunk hole 32 is provided with a spring 4 and abuts the first countersunk hole 18. The top block 3 is provided with a protrusion 33, and passes through the notch 17 and the give way hole 26 to abut the clamping part 22. The end face shape of the protrusion 33 is set to be an arc shape. The limit block 31 is used in conjunction with the limit groove 16, and the second countersunk hole 32 increases the accommodating space of the spring 4. The elastic force of the spring 4 ensures that the clamping part 22 has sufficient contraction force to be applied to the surface of the wire. The elastic force of the spring 4 is concentratedly applied to a line of the clamping part 22 through the protrusion 33. The protrusion 33 is set to a circular arc structure to reduce the wear of the protrusion 33 and the clamping part 22 when the conductive part 2 rotates.

[0033] The use principle of the utility model is now described as follows:

[0034] Insert the wire into the wire cavity 21, pre-press the wire with the clamping part 22, align the avoidance through hole 27 with the protrusion 33, align the fixing block 24 with the clearance groove 13, apply downward pressure to the conductive part 2, first apply thrust to the protrusion 33 at the connection between one end of the clamping part 22 and one end of the clearance through hole 26, so that the protrusion 33 is partially retracted to the notch 17, and the spring 4 is stored, the fixing block 24 is inserted into the clearance groove 13, and the conductive part 2 is rotated, as the protrusion 33 gradually moves away from the clamping part 22 and the clearance through hole 2 6 is connected and fixed, the resistance of the spring 4 is gradually reduced, and the elastic force applied to the protrusion 33 is gradually increased, so that the pressing part 22 presses the wire into the wire-containing cavity 21, thereby achieving the function of fixing the wire. At this time, the fixing block 24 enters the fixing groove 14 and abuts against the side wall of the fixing groove 14, completing the connection between the conductive member 2 and the cavity 11, and the protrusion 33 abuts against the side wall of the yielding through hole 26 and is misaligned with the avoiding through hole 27. The support of the above two makes the connection between the conductive member 2 and the cavity 11 stable and reliable;

[0035] When it is necessary to remove the wire, the conductive part 2 is rotated in the opposite direction. As the protrusion 33 gradually approaches the connection and fixing point between the clamping part 22 and the yielding through hole 26, the resistance encountered by the spring 4 gradually increases, and the protrusion 33 retracts a part to the notch 17. The clamping part 22 cannot apply enough tightening force to the wire. At this time, the wire can be pulled out of the wire-containing cavity 21, thereby facilitating replacement.

[0036] The above design scheme can enable the product to achieve the advantages of stable connection, convenient disassembly and improved resource utilization.

[0037] The above content is a further detailed description of the utility model in combination with specific implementation methods. It cannot be determined that the specific implementation of the utility model is limited to these descriptions. For ordinary technicians in the technical field to which the utility model belongs, without departing from the concept of the utility model, they can also make several simple deductions or substitutions, which should be regarded as belonging to the scope of protection determined by the claims submitted for the utility model.
