Description

Technical Field

[0001] The utility model relates to the technical field of cable connection, in particular to a copper wire cable connector which is easy to connect. Background Art

[0002] A cable is an electrical energy or signal transmission device, usually composed of several or several groups of twisted wires. When the cable is in use, a connector, also known as a "terminal" or "wire nose", needs to be installed at the end of the cable to facilitate connection with other electrical equipment, which can make the connection between the cable and the electrical equipment more secure and safer. The current connection method is to strip the insulating sheath at the end of the cable, and then install the internal wire core into the connector. The existing connectors are divided into plug-in type and crimping type. When using the crimping connector, the core of the cable is placed in the wiring groove, and then the pressure plates on both sides are pressed toward the direction of the core to fix the core. However, in actual use, for cables with thicker cores, part of the core will be exposed when pressed, which is prone to short circuit or leakage. For cables with thinner cores or those that match the connector, the core will be separated into two parts or not firmly fixed when pressed, and the overall wrapping of the core is poor, which poses certain risks. Utility Model Content

[0003] In order to solve the technical problems existing in the above-mentioned background technology, the utility model provides a copper wire cable connector which is easy to connect.

[0004] The technical solution of this utility model is as follows:

[0005] A copper wire cable connector that is easy to connect, installed at the end of a cable, and used to connect to an electric power device, comprising:

[0006] A connecting portion, wherein a connecting hole is formed through the end surface of the connecting portion for connecting to an electric device;

[0007] The accommodating portion is fixedly connected to the bottom end of the connecting portion and is used to accommodate the core of the cable;

[0008] The first crimping portion and the second crimping portion are respectively connected horizontally to the two sides of the accommodating portion, and both can surround the accommodating portion to form an accommodating space with the accommodating portion, and can compress the wire core;

[0009] The first crimping portion and the second crimping portion can both surround the connection between the other and the accommodating portion and abut against the accommodating portion.

[0010] In order to facilitate the placement of the cable core, the cross-section of the accommodating portion is an arc surface.

[0011] Different from the prior art, one of the main design points of this solution is that the first crimping portion and the second crimping portion are polygonal shapes that can surround and be connected to each other.

[0012] The specific design of the first crimping part and the second crimping part is that both of them are in the shape of a right triangle and are arranged symmetrically with respect to the receiving part, and the two groups of right angle sides are parallel to each other. The first crimping part and the second crimping part in the shape of a right triangle can respectively surround one side of the receiving part and surround the connection between the other and the receiving part, so as to surround the wire core in the receiving part, thereby increasing the length of the surrounding compared with the prior art, and can wrap the wire core to avoid exposure, thereby improving safety performance.

[0013] In order to ensure that the wire core can be completely surrounded, the first crimping portion is higher than the second crimping portion, and the horizontal right-angled sides of the first crimping portion and the second crimping portion are flush with the upper and lower ends of the accommodating portion respectively.

[0014] In order to accommodate the triangular ends of the first crimping portion and the second crimping portion away from the accommodating portion and ensure the flatness around the first crimping portion and the second crimping portion, the accommodating portions at the lower ends of the first crimping portion and the second crimping portion are provided with notches.

[0015] In order to improve the stability of the first crimping part and the second crimping part after surrounding, a limiting block is provided at the center of the bevel of the first crimping part, and a plurality of limiting grooves are provided on the bevel of the second crimping part, and the limiting block can be matched with any limiting groove. After surrounding is completed, the limiting block is pressed into the limiting groove to ensure the stability of the two.

[0016] In order to ensure the stability of the wire core having the same diameter as the accommodating space after being wrapped, and to be able to wrap the wire core with a smaller diameter, there is a limiting groove capable of accommodating the limiting block, and the limiting groove is arranged upward from the center position of the hypotenuse and along the length direction of the hypotenuse.

[0017] In order to further fix and tighten the wire core after the wire core is wrapped, threaded holes are formed through the end surfaces of the first crimping portion and the second crimping portion for installing bolts to fix the wire core.

[0018] In order to increase the friction between the wire core and the accommodating portion, the first crimping portion and the second crimping portion and ensure the stability of the wire core, anti-slip grooves are provided on the end surfaces of the accommodating portion, the first crimping portion and the second crimping portion.

[0019] The beneficial effects of the utility model are as follows: the utility model is a copper wire cable connector that is easy to connect. Firstly, the core of the cable and the connector can be fixed by the accommodation part in cooperation with the accommodation space surrounded by the first crimping part and the second crimping part, and the connection of the cable and the power equipment is realized by cooperating with the connecting part; secondly, different from the prior art, the first crimping part and the second crimping part in the shape of a right-angled triangle can respectively surround one side of the accommodation part and surround the notch where the other party is connected to the accommodation part, so as to surround the core in the accommodation part, thereby increasing the coverage area of ​​the core, wrapping the core as a whole to avoid exposure, greatly improving the safety performance, and facilitating the connection between the core and the connector; finally, the core can be further fixed by the threaded hole, and the anti-slip grooves provided in the accommodation part, the first crimping part and the second crimping part increase the friction between the contact part of the core and the connector, thereby ensuring the stability of the connection of the core.

[0028] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings.

[0029] Example

[0030] As mentioned in the background technology, a connector needs to be installed at the end of the cable as a transit to connect with other power equipment. The connector is divided into plug-in type and crimp type, which are two connection methods used in different occasions and conditions. The existing crimping connector has many disadvantages when used. Since the cable core is relatively loose after the rubber is removed, the existing connector cannot fully cover the core with a larger diameter when crimping, and a single core is easily exposed. For cores with the same diameter or slightly smaller diameter, due to the consistent length of the crimping part, abutment is likely to occur, resulting in gaps in the wrapping, and the fixation is not firm, or the core is divided into two, which will also protect the core. Therefore, the inventor improved the existing connector and designed a new connector, which is described in detail below with reference to the drawings.

[0031] This embodiment provides a copper wire cable connector that is easy to connect. The connector is installed at the end of the cable and is used to connect to the power equipment. Figure 1-Figure 3 First, the connector includes a connecting part 1, the upper end of the connecting part 1 is arc-shaped, and the lower end is trapezoidal. A connecting hole 2 is opened through the end face of the connecting part 1, which can be connected to the power equipment, thereby realizing the fixation of the connecting head and the power equipment. Secondly, in order to facilitate the connection of the core of the cable, a receiving part 3 is also fixedly connected to the bottom end of the connecting part 1, and the core of the cable can be placed along the length direction of the receiving part 3. Since the core of the cable is cylindrical as a whole, the cross-section of the receiving part 3 is an arc surface, that is, an arc-shaped groove is provided in the receiving part 3, which is convenient for placing the core in the groove and ensures the stability of the placement of the core.

[0032] In this embodiment, the wire core is first placed on the accommodating portion 3, and then the upper end surface of the wire core needs to be pressed. Specifically, the connector also includes two crimping parts, namely a first crimping part 4 and a second crimping part 5, which are horizontally connected to the two sides of the accommodating portion 3, connected to the arc-shaped edge of the accommodating portion 3, and are integrally stamped. Moreover, both can be wrapped in the direction of the accommodating portion 3. It is necessary to bend the first crimping part 4 and the second crimping part 5 with the assistance of an external force or with the help of a tool, and the first crimping part 4 and the second crimping part 5 after bending are combined. Figure 4 , cooperating with the accommodating portion 3 to form an accommodating space 6, which can compress the wire core.

[0033] In this embodiment, combined with Figure 3 Unlike the prior art, which is also one of the main design points of the present invention, the first crimping portion 4 and the second crimping portion 5 can both wrap around the connection between the other and the accommodating portion 3 and abut against the accommodating portion 3, that is, the first crimping portion 4 and the second crimping portion 5 can both bypass the upper end of the wire core, pass through the vertical center line of the accommodating portion 3, and wrap around the end of the other crimping portion, so as to cover the entire area of ​​the wire core exposed outside the accommodating portion 3, wrap the wire core as a whole, and avoid exposure of a relatively loose single wire core.

[0034] Specifically, in this embodiment, the first crimping portion 4 and the second crimping portion 5 are polygons that can be surrounded and spliced ​​with each other. When surrounding, the first crimping portion 4 and the second crimping portion 5 can complement each other to cover the wire core. Specifically, the first crimping portion 4 and the second crimping portion 5 are both right-angled triangles, and are centrally symmetrically arranged with respect to the accommodating portion 3. The two groups of right-angled sides are parallel to each other, that is, the first crimping portion 4 and the second crimping portion 5 are horizontally aligned into a parallelogram. However, in order to achieve the overall coverage of the wire core, the first crimping portion 4 is higher than the second crimping portion 5, and the horizontal right-angled sides of the first crimping portion 4 and the second crimping portion 5 are respectively flush with the upper and lower ends of the accommodating portion 3. The other right-angled side is respectively connected to the corresponding edge of the accommodating portion 3. When surrounding, the first crimping portion 4 and the second crimping portion 5 in the shape of a right-angled triangle are bent toward one side of the wire core, and the right-angled sides that are flush with each other are wrapped around the upper and lower edges of the accommodating portion 3, and the two oblique sides are abutted against each other after the surrounding is completed, and cooperate with the arc-shaped accommodating portion 3 to form a cylinder.

[0035] Moreover, after the wire core is crimped, the stability is further improved. Threaded holes 10 are formed through the end faces of the first crimping part 4 and the second crimping part 5 for installing bolts to fix the wire core. Through the cooperation of the bolts and the threaded holes 10, the wire core can be tightly pressed against the accommodating part 3. In order to increase the friction between the wire core and the accommodating part 3, the first crimping part 4 and the second crimping part 5, anti-slip grooves 11 are formed on the end faces of the accommodating part 3, the first crimping part 4 and the second crimping part 5, and are all arranged on the side that can contact the wire core. The anti-slip grooves 11 of the first crimping part 4 and the second crimping part 5 are staggered in the vertical direction with the anti-slip grooves 11 of the accommodating part 3, which can increase the anti-slip area of ​​the wire core.

[0036] On the basis of the above structure, since the first crimping part 4 is higher than the second crimping part 5, a notch 7 is provided in the accommodating part 3 at the lower end of the first crimping part 4 and the lower end of the second crimping part 5. The shape of the notch 7 is adapted to the corners of the two crimping parts away from the accommodating part 3. In order to improve the safety during crimping and reduce the threat to the staff, the corner away from the accommodating part 3 is set to an arc shape to avoid the sharp point from stabbing the staff.

[0037] In order to improve the stability of the first crimping part 4 and the second crimping part 5 after surrounding, a limiting block 8 is set at the center position of the hypotenuse of the first crimping part 4, and a plurality of limiting grooves 9 are opened on the hypotenuse of the second crimping part 5, and the limiting block 8 can be adapted to any limiting groove 9, and the limiting block 8 and the limiting groove 9 are both trapezoidal in shape. After the two are surrounded, the limiting block 8 is pressed into the limiting groove 9 so that the limiting block 8 and the limiting groove 9 are buckled, reducing the misalignment of the crimping part, and at least ensuring that there is a limiting groove 9 at the center position of the hypotenuse of the second crimping part 5, so that for the wire core with the same diameter as the accommodating space 6, and most of the wire cores with the same diameter, the limiting can be effectively completed.

[0038] It should be noted that a plurality of limit grooves 9 are arranged upward from the center position of the hypotenuse and along the length direction of the hypotenuse. The purpose of the design here is that for wire cores with smaller diameters, when the first crimping portion 4 and the second crimping portion 5 are surrounded, the end away from the accommodating portion 3 will exceed the position of the notch 7, and the middle limit block 8 and the middle limit groove 9 are staggered with each other, and the upper limit groove 9 can provide a limit space for the limit block 8, so that the present connector can be used for crimping of wire cores of larger sizes.
