[0028] Now, the present utility model will be further described in detail with reference to the accompanying drawings. These drawings are all simplified schematic diagrams, only illustrating the basic structure of the present utility model in a schematic manner. Therefore, they only show the components related to the present utility model. Directions and references (such as up, down, left, right, etc.) can only be used to assist in the description of the features in the drawings. Therefore, the following detailed implementation manners are not adopted in a restrictive sense, and the scope of the claimed subject matter is only defined by the appended claims and their equivalent forms.

[0029] As Figures 1 - 4 shown, an integrated heart-shaped hanging ring includes:

[0030] A wire clip, which includes two clips 1 that are inserted and matched with each other. Each clip 1 includes an insertion part 101, a clamping opening 102 located on one side of the insertion part 101, and a bayonet 103 formed by a depression on the other side of the insertion part 101. The two clamping openings 102 are arranged opposite to each other and enclose a clamping ring for clamping a catenary or a contact wire. The two bayonets 103 are arranged opposite to each other and enclose a card slot;

[0031] And a heart-shaped ring 2, which includes a ring body 201 and a clamping part 202 for being inserted into the card slot and rotatably matched with the card slot. As Figure 7 shown.

[0032] During installation, the clamping part 202 of the heart-shaped ring 2 is placed between the two clips 1, and the two clips 1 are made to approach each other and be inserted and fixed. The card slot formed by the two bayonets 103 will clamp the clamping part 202, so that the wire clip and the heart-shaped ring 2 will not become loose. At the same time, the wire clip and the heart-shaped ring 2 are rotationally matched, avoiding stress concentration of the current-carrying wire.

[0033] In some examples, clamping teeth 1011 are provided on each insertion part 101, and the clamping teeth 1011 on the two insertion parts 101 are meshed with each other to lock the two clips 1 so that they cannot become loose and are easy to disassemble under the action of an external force.

[0034] In some examples, each plugging part 101 includes a base 1012 and a plurality of plugging posts 1013 that protrude from the base 1012 and are spaced apart. A plugging groove 1014 is formed between the plugging posts 1013 and the base 1012. The plugging posts 1013 on the two clamping plates 1 correspond to the plugging grooves 1014 one by one, and each plugging post 1013 is inserted into its corresponding plugging groove 1014. The plugging posts 1013 are provided with rounded corners. The plugging and fixing of the two clamping plates 1 is achieved through the cooperation of the plugging posts 1013 and the plugging grooves 1014. The number of the plugging parts 101 and the plugging grooves 1014 can be, but is not limited to, two, three, etc. In this embodiment, there are two. One of the plugging posts 1013 is located in the middle of the base 1012, and the other plugging post 1013 is located at the end of the base 1012, as Figure 5 shown.

[0035] In some examples, as Figure 6 shown, the cross-sectional area of the plugging post 1013 gradually decreases from the clamping plate 1 where it is located to the direction of the other clamping plate 1, and the cross-sectional area of the plugging groove 1014 gradually increases from the clamping plate 1 where it is located to the direction of the other clamping plate 1. Among the two opposite side surfaces of the plugging post 1013 and the plugging groove 1014, one is a straight surface and the other is an inclined surface, thus forming a wedge-shaped structure of the plugging post 1013 and the plugging groove 1014. During the process of the two clamping plates 1 being plugged into each other, when the left clamping plate 1 on the left moves to the right, it also moves forward at the same time. When the right clamping plate 1 on the right moves to the left, it also moves backward at the same time, so that the two are gradually clamped in the front-rear direction.

[0036] In some examples, as Figure 5 shown, the clamping opening 102 has an extension section 1021 that extends beyond the plugging post 1013. The lower surface of the extension section 1021 and the upper surface of the base 1012 are both provided with the above-mentioned clamping teeth 1011. That is, two sets of clamping teeth 1011 are provided on each clamping plate 1, and the clamping teeth 1011 on the two clamping plates 1 are engaged with each other to lock the two clamping plates 1.

[0037] In some examples, the card slot is a stepped slot, which includes a large-diameter slot and a small-diameter slot that are communicated with each other. The card-connecting part 202 includes a large-diameter section 2021 that cooperates with the large-diameter slot and a small-diameter section 2022 that cooperates with the small-diameter slot. Through the cooperation of the small-diameter slot and the small-diameter section 2022, the card-connecting part 202 and the card slot can be relatively locked so that the two will not become loose, and the cross-sections of the card slot and the card-connecting part 202 are both circular, so that the card-connecting part 202 can rotate inside the card slot.

[0038] In some examples, a wire groove 2011 is formed on the outer peripheral wall of the ring body 201, and a wire passing hole 1015 is formed on the plugging part 101. The setting of the wire passing hole 1015 solves the problem of collision between the suspension string and the wire clamp, and reduces the potential safety hazard.

[0039] In some examples, a plurality of anti-slip grooves are formed inside the clamping opening 102 for clamping the catenary, which is used to increase the friction between the clamping opening 102 and the catenary and improve the clamping effect.

[0040] In some examples, weight-reducing grooves 104 are formed on both the plugging portion 101 and the clamping opening 102. The weight-reducing groove 104 on the plugging portion 101 is formed on the plugging post 1013 at the end, and the weight-reducing groove 104 on the clamping opening 102 is formed on the outer side of the clamping opening 102.

[0041] In some examples, an integral suspension string includes the above-mentioned integral heart-shaped suspension loop, and is characterized in that: it further includes a catenary suspension clamp, a contact wire suspension clamp and a suspension string. The heart-shaped suspension loop includes an upper heart-shaped suspension loop between the catenary suspension clamp and the upper end of the suspension string and a lower heart-shaped suspension loop between the contact wire suspension and the lower end of the suspension string. The catenary suspension clamp and the contact wire suspension clamp are both the above-mentioned clamps.

[0042] Taking the above-mentioned ideal embodiments according to the present invention as an inspiration, through the above description, relevant staff can completely make various changes and modifications without departing from the technical idea of the present invention. The technical scope of the present invention is not limited to the content in the specification, and its technical scope must be determined according to the scope of the claims.
