Description

Technical Field

[0001] The utility model relates to the technical field related to a connecting wire seat, in particular to a connecting wire seat with a shrinking function. Background Art

[0002] A terminal block is a device that clamps two or more power wires to achieve or maintain contact between them. There are many types of existing terminal blocks, such as those used in various electrical appliances or electrical appliance boxes to achieve the docking of wires. Taking air conditioners as an example, the terminal block used in the prior art is composed of four parts, namely, an insulating terminal block body, a conductive steel sheet, a cross-slot flat head screw, and a terminal block. When in use, the wire is connected to the terminal block. When the input or output end of the terminal block connected to the wire is respectively inserted into the corresponding terminal port, the screw is tightened with a screwdriver to achieve the docking of the wire:

[0003] Publication number CN200944442Y discloses a terminal block, in which two elastic metal sheets of different lengths are arranged in a "λ" shape in the base of the terminal block, and the end of the power cord is embedded in the connection of the elastic metal sheets. The metal sheets do not need to be bent, and there is no need to set serrations on the edges, which greatly reduces the cost; at the same time, the two metal sheets are fixed in the base, and the force applied to the power cord is the restraining force applied to the elastic metal sheets by the inner wall of the base, so the fastening effect is good and it is not easy to fall off; however, when the above device is used, there are still certain shortcomings. First, in actual use, it is necessary to connect multiple groups of connecting wires, but the existing connecting wire seat only connects these groups and does not have the function of shrinking to connect the connecting wires, resulting in too many connecting positions being exposed to the outside, which will cause oxidation of the contact surface over time.

[0004] Therefore, we propose a connecting wire holder with a retracting function which can solve the above problems well. Utility Model Content

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] See also Figure 1-Figure 6 , the utility model provides the following technical solutions:

[0028] Embodiment 1: The existing connection wire holder only connects the several groups and does not have the function of shrinking to connect the connection wires, resulting in too many connection positions being exposed to the outside, which may cause oxidation of the contact surface over time. Please refer to the attached Figure 1 , Attachment Figure 2 , Attachment Figure 5 and attached Figure 6, including a connecting wire main seat 1, and a connecting wire hole 2 is opened on the surface of the connecting wire main seat 1, a group of conductive elastic sheets 3 are fixed at the bottom end of the connecting wire hole 2, and connecting wire secondary seats 13 are arranged at the left and right ends of the connecting wire main seat 1; a contraction mechanism is arranged at the two sides of the bottom of the connecting wire main seat 1, and the two groups of connecting wire secondary seats 13 can be moved through the setting of the contraction mechanism, which can adapt to the connection processing of multiple groups of connecting wires, and the contraction mechanism includes a rotating block 9 rotatably connected to the bottom position of the connecting wire main seat 1, and a connecting gear 10 with a fixed end position of the rotating block 9, a first rack 11 and a second rack 12 are meshed and connected at the top outer position of the connecting gear 10, and the other ends of the first rack 11 and the second rack 12 are respectively fixed on one side of a group of connecting wire secondary seats 13, so that the connecting wire secondary seats 13 can be contracted. A bonding plate 14 is provided on one side of the connecting wire sub-seat 13, and a guide rail 15 is fixed at the bottom of the connecting wire sub-seat 13. The outer side of the guide rail 15 is bonded to the inside of the slide groove 16, which can be easily moved. The size of the first rack 11 is the same as that of the second rack 12, and the directions of movement of the two sets of connecting wire sub-seats 13 are opposite, which can ensure that the connecting wire sub-seat 13 forms a sliding mechanism between the guide rail 15 and the inside of the slide groove 16. By rotating the rotating block 9 arranged at the bottom position of the connecting line main seat 1, the connecting gear 10 connected to the bottom position of the rotating block 9 can be rotated inside the connecting line main seat 1. Since the outer side of the connecting gear 10 is meshedly connected with the first rack 11 and the second rack 12, the first rack 11 and the second rack 12 can slide inside the connecting line main seat 1, and the first rack 11 and the second rack 12 can drive the connecting line secondary seat 13 to slide inside the connecting line main seat 1. Since the guide rail 15 arranged at the bottom position of the connecting line secondary seat 13 will also slide inside the slide groove 16, the setting of the contraction mechanism can avoid too many connection positions being exposed to the outside, which will cause the problem of oxidation of the contact surface over time.

The conductive mechanism is also provided inside the main seat 1 of the connecting wire, and the top position of the locking screw 4 is also rotatably connected to the top position of the main seat 1 of the connecting wire. By rotating the corresponding locking screw 4, the locking screw 4 can be rotated at the top position of the main seat 1 of the connecting wire and the secondary seat 13 of the connecting wire, and the insulating connecting sleeve 5 can drive the conductive elastic sheet 3 to move inside the connecting wire hole 2, so that the conductive elastic sheet 3 can fit and limit the connecting wire, and prevent the connecting wire from being offset and falling off.

[0030] Embodiment 3: In order to protect the interior of the connecting wire main seat 1, please refer to the attached Figure 1 -Attached Figure 4 , the slide grooves 16 are provided at both sides of the bottom of the receiving block 7, and the receiving block 7 has a receiving cavity 8 inside which can accommodate the connecting wire secondary seat 13 and the locking screw 4 at the top of the connecting wire secondary seat 13. A gasket is provided at one side of the bonding plate 14, and the outer side of the gasket is bonded to the outer side of the receiving cavity 8 provided by the receiving block 7, so that the inside of the receiving cavity 8 can be closed. A connecting seat 6 is installed at the rear side of the connecting wire main seat 1 to facilitate the positioning of the device. The connecting wire secondary seat 13 can be moved to drive the bonding plate 14 to slide. Since the bonding plate 14 is in close contact with the side wall of the receiving cavity 8, the connecting wire main seat 1 and the inside of the receiving block 7 can be closed, so as to achieve a sealing effect.
