DETAILED DESCRIPTION

[0023] The utility model is described in detail below with reference to the accompanying drawings. Figures 1 to 7 shown.

[0024] Example 1: See Figure 1 , Figure 2 A terminal block comprises a connecting tube 2 with openings at both ends, one end of the connecting tube 2 being a connecting end, and a plurality of slits 21 being provided on the side of the connecting end; abutment sheets 22 are formed between adjacent slits 21, and a pressing ring 3 for pressing the abutment sheets 22 inwardly is provided on the outer sleeve of the connecting tube 2, and the pressing ring 3 can move relative to the connecting tube 2 along the axial direction of the connecting tube 2. When connected with a metal wire, the metal wire is inserted into the connecting end, and the pressing ring 3 is moved outward, and at least part of the pressing ring 3 is sleeved on the outside of the metal wire.

[0025] When the terminal is in use, the end of the wire 10 is peeled to expose the metal part, and the metal part (i.e., the metal wire) is inserted into the connecting tube 2; the inner diameter of the outer end of the connecting end is slightly larger than the outer diameter of the metal wire; at this time, the pressing ring 3 is pushed to move so that the pressing ring 3 enters the connecting end and presses against the abutment sheet 22; the abutment sheet 22 is deformed and bends inward, and the abutment sheet 22 wraps the metal part and forms an extrusion.

[0026] Generally speaking, when the pressure ring 3 enters the connection end and contacts the abutment sheet 22, the abutment sheet 22 is deformed and abuts against the metal wire; the connection is completed; and when the pressure ring 3 is located on the outside of the metal wire, the wire 10 is still at risk of detachment. At this time, the outer end of the abutment sheet 22 is squeezed and deformed. Since the pressure ring 3 is located on the outside of the metal wire, the outer end of the connection tube 2 will be deformed into a bell mouth with a gradually narrowing opening. Once subjected to a large external force, such as a pulling force, the external force will overcome the friction between the metal part and the abutment sheet 22, causing the outer diameter of the opening outside the connection end to suddenly increase, and the metal part is detached. Therefore, it is necessary to avoid the phenomenon of the increase in the outer diameter of the end opening of the connection tube 2. The present application moves the pressure ring 3 so that at least part of the pressure ring 3 is sleeved on the outside of the metal wire. The partial pressure ring 3 or the entire pressure ring 3 sleeved on the outside of the metal wire will prevent the inner end opening aperture of the connection end from expanding and be restricted by the pressure ring 3, thereby avoiding the detachment of the metal wire.

[0027] See also Figure 2 In order to facilitate the insertion of the metal wire, the abutment sheet 22 is tilted outward in this embodiment, and the connection end is in a trumpet shape. The abutment sheet 22 is set to be tilted, and the connection end is in a trumpet shape with a gradually narrowing opening. 1. It can facilitate the insertion of the metal wire; the outer opening is large and the inner opening is small, which is convenient for guiding the insertion of the metal wire; 2. When the pressure ring 3 moves outside, it gradually squeezes the abutment sheet 22 inward.

[0028] Of course, other methods can be used to enable the pressure ring 3 to press the pressing sheet, such as Figure 3 As shown, the thickness of the contact piece 22 gradually decreases from the outside to the inside, and the outer surface of the contact piece 22 is inclined.

[0029] In practice, if the thickness of the abutment sheet 22 is consistent, the caliber formed by the abutment sheet 22 does not change much under the extrusion of the pressing ring 3 during the movement. In order to enable the abutment sheet 22 to better wrap the metal wire, the technical solution sets the thickness of the abutment sheet 22 to be gradually deformed. When the pressing ring 3 moves outward, the pressing ring 3 gradually squeezes the abutment sheet 22, so that the outer diameter of the abutment sheet 22 is consistent with the inner diameter of the pressing ring 3, and the abutment sheet 22 bends inward. As the pressing ring 3 moves, the deformation of the abutment sheet 22 gradually increases, and at the same time, the inner diameter of the connecting end gradually decreases, so that the metal wire can be clamped quickly.

[0030] Embodiment 2: A connector, comprising an insulating shell 8, the insulating shell 8 is provided with a connecting through hole, and the two ends of the connecting through hole are respectively connected to the above-mentioned connecting terminals, and the two connecting terminals are electrically connected; the apertures of the two ends of the connecting through hole are enlarged to form an expansion hole, the connecting end of the connecting terminal is located in the expansion hole, and a movable space 82 is formed between the side wall of the expansion hole and the connecting terminal, and the pressure ring 3 is located in the movable space 82; at least one movable groove 81 is respectively provided at both ends of the insulating shell 8, and an insulating driving ring 6 is sleeved on the end of the insulating shell 8, and a driving block 61 is connected to the inner side of the driving ring 6, and the driving block 61 passes through the movable groove 81 and extends into the movable space 82, and the driving block 61 is located on the rear side of the pressure ring 3.

[0031] See also Figure 7 When the connector is in use, it is connected to the two wires 10 through the wiring terminals at both ends, so as to achieve the purpose of connecting the two wires 10; when connecting, the ends of the wires 10 are peeled, and the metal parts exposed outside are inserted into the wiring terminals; then the drive ring 6 is pushed, and the drive ring 6 moves outward, and the drive block 61 of the drive ring 6 pushes the pressure ring 3 to move outward; when the pressure ring 3 moves, the abutment piece 22 at the connection end is gradually squeezed inward, and the connection is achieved by clamping the metal part. Secondly, in order to make the thrust of the drive ring 6 on the pressure ring 3 uniform, the drive ring 6 is evenly provided with 2, 3 or 4 drive blocks 61, and the two ends of the insulating shell 8 are respectively provided with 2, 3 or 4 movable grooves 81.

[0032] Secondly, when manufacturing the connector, the pressure ring 3 can be firstly sleeved on the outside of the connecting tube 2, and then the two connecting tubes 2 and the insulating shell are integrally injection molded; or: the insulating shell is first molded, and then the two connecting tubes 2 are sleeved on both ends of the insulating shell, and thermally installed by means of thermal expansion and contraction; the two opposite ends of the two connecting tubes 2 are abutted against each other, or sleeved, or connected through other conductors 1.

[0033] See also Figure 6 Preferably, a columnar conductor 1 is provided in the connecting through hole, and the connecting tubes 2 of the two connecting terminals are respectively sleeved with the two ends of the conductor 1.

[0034] The conductor 1 can be a solid body, such as an aluminum cylinder; or a tube, such as an aluminum tube. The conductor 1 can 1. increase the overall strength to prevent the connector from being deformed due to the hollow middle when subjected to a large external force; 2. realize the electrical connection of the terminals at both ends. Preferably, the conductor is a hollow tube structure. After being set as a tube structure, the weight can be reduced, and secondly, the cost can be reduced.

[0035] See also Figure 4 , Figure 5 , Figure 6 The two ends of the insulating shell 8 are in a circular ring shape and are provided with external threads. The two ends of the insulating shell 8 are respectively threadedly connected with push rings 7, and the push ring 7 is located at the rear side of the driving ring 6.

[0036] After the driving ring 6 is used to push the pressing ring 3 to move, the driving ring 6 may leave the pressing ring 3, causing the pressing ring 3 to move inward; secondly, when pushing the driving ring 6 to move, the driving ring 6 has a small outer diameter and a small thickness; the operation is inconvenient. For this reason, the technical solution is provided with a push ring 7, which is threadedly connected to both ends of the insulating housing 8. By rotating the push ring 7, the push ring 7 moves along the axial direction and pushes the driving ring 6 to move. And the driving ring 6 is prevented from moving in the reverse direction.

[0037] See also Figure 4 , Figure 5 , Figure 6 The end of the insulating shell 8 is sleeved with an insulating shell 5, and the shell 5 is provided with an annular socket 52 that matches the end of the insulating shell 8, and a plug-in ring 51 that matches the activity space 82. The end of the insulating shell 8 is inserted into the annular socket 52, and the plug-in ring 51 is inserted into the activity space 82.

[0038] The sleeve 5 can be connected with the end of the insulating shell 8 by interference fit; after the sleeve 5 is set, it can avoid 1. the drive ring 6 being separated from the end of the insulating shell 8; 2. the pressure ring 3 being separated from the connecting tube 2.

[0039] Secondly, a spring 4 is provided between the plug-in ring 51 and the pressure ring 3 , and the spring 4 is sleeved on the outer side of the abutment piece 22 .

[0040] In order to make the connector reusable, the pressing ring 3 can be reset; therefore, a spring 4 is provided; when the connector needs to be separated from the wire 10, the push ring 7 is rotated away from the end, and the drive ring 6 is pushed away from the end; at this time, the pressing ring 3 moves under the thrust of the spring 4, and the pressing ring 3 is away from the corresponding wire 10, and then the wire 10 can be pulled out from the corresponding connection terminal.

[0041] The above contents are only preferred embodiments of the utility model. For ordinary technicians in this field, according to the concept of the utility model, there will be changes in the specific implementation method and application scope. The content of this specification should not be understood as a limitation on the utility model.
