[0005] In order to achieve the above object, the embodiment of the utility model adopts the following technical solution:

[0006] A cable connector assembly includes two spline-shaped bend-resistant cables butted against each other, a connector and a locking bolt. A conductor is provided in the connector, and spline grooves are provided at both ends of the connector. The spline grooves are relatively arranged on both sides of the conductor. The spline-shaped bend-resistant cable extends into the spline grooves and fits with the conductor. A plurality of locking holes are provided around the connector. The locking bolt is threadedly connected in the locking hole and abuts against the outer contour of the spline-shaped bend-resistant cable.

[0007] According to one aspect of the utility model, a buffer pad is fixed to the end of the locking bolt.

[0008] According to one aspect of the utility model, the buffer pad is made of rubber material.

[0009] According to one aspect of the utility model, an installation gap is left between the spline groove and the outer contour of the spline-shaped bend-resistant cable.

[0010] According to one aspect of the utility model, the spline groove includes an integrated main body groove and a clamping groove, the clamping grooves are evenly distributed at intervals around the main body groove, and the locking hole is connected to the main body groove.

[0011] According to one aspect of the utility model, the main body groove is a columnar groove, and the clamping groove is a trapezoidal groove.

[0012] According to one aspect of the utility model, the connector is made of plastic.

[0013] The advantages of the implementation of the utility model are as follows: two spline-shaped anti-bending cables are respectively inserted into the spline grooves at both ends of the connector, and are fitted and abutted against the conductor, and then the locking bolt is screwed into the locking hole, so that the threaded end of the locking bolt abuts against the outer contour of the spline-shaped anti-bending cable; in this way, the cable connector assembly can be suitable for the connection of spline-shaped anti-bending cables, which is easy to use, stable, safe and reliable. Through the adaptive structural setting of the spline groove and the spline-shaped anti-bending cable, the cable connector assembly can prevent the cable from rotating loose, making the structural connection more stable and reliable.

[0020] Embodiment 1

[0021] like Figure 1 , Figure 2 As shown, a cable connector assembly includes a connector 1, a locking bolt 2, and two spline-shaped anti-bending cables 3 to be connected. A conductor 4 is provided in the connector 1, and spline grooves 5 are provided at both ends of the connector 1. The spline grooves 5 are relatively arranged on both sides of the conductor 4. The two spline-shaped anti-bending cables 3 are respectively extended into the spline grooves 5 at both ends of the connector 1 and fit and abut against the conductor 4. A plurality of locking holes 8 are circumferentially provided on the connector 1, and the locking bolts 2 are threadedly connected in the locking holes 8 and abut against the outer contour of the spline-shaped anti-bending cables 3.

[0022] In this embodiment, an installation gap 7 is left between the spline groove 5 and the outer contour of the spline-shaped bend-resistant cable 3, so as to facilitate the butt-jointing installation of the spline-shaped bend-resistant cable 3.

[0023] In practical applications, the spline-shaped bending-resistant cable 3 is composed of a central cable conductor and an outermost insulating sheath, and the insulating sheath is provided with a plurality of protective protrusions equidistantly in the circumferential direction, and the protective protrusions are in the shape of an isosceles trapezoid, so that the shape of the entire cable is in the shape of a "spline"; there are four groups of protective protrusions in this embodiment. This is a prior art and will not be described in detail.

[0024] In this embodiment, the structural shape of the spline groove 5 is adapted to the structural shape of the spline-shaped bending-resistant cable 3. The spline groove 5 includes an integrated main body groove and a clamping groove, the clamping grooves are evenly distributed around the main body groove, the locking hole 8 is connected to the main body groove, and the position of the locking hole 8 corresponds to the position of the main body groove.

[0025] In this embodiment, the main groove is a columnar groove, and the snap-in groove is a trapezoidal groove. The structural shape and number of the snap-in groove are respectively adapted to the structural shape and number of the protective protrusions. This not only facilitates the installation of the spline-shaped anti-bending cable 3, but also prevents the cable from rotating and loosening, making the cable connection more stable and reliable.

[0026] In this embodiment, the locking hole 8 is a threaded hole, which is threadedly connected to the locking bolt 2; during implementation, a light hole structure plus a threaded sleeve can also be used to be threadedly connected to the locking bolt 2. The number of locking holes 8 or the number of locking bolts 2 is adapted to the number of protective protrusions, or the number of main groove parts between adjacent clamping grooves. In this embodiment, there are four locking holes 8 at each end of the connector 1 in the circumferential direction, each four forming a group, and two groups are provided along the axial direction of the connector 1. During implementation, the locking bolt 2 can be screwed into the locking hole 8 in the horizontal direction only, which can reduce the operation steps and make it more convenient and flexible to use.

[0027] In this embodiment, the connector 1 is made of plastic for insulation protection and is cylindrical. The conductor 4 is a metal conductor 4 in the shape of a cylindrical block. The connector 1 and the conductor 4 are a whole; during implementation, that is, during actual production, the conductor 4 can be fixed in the connector 1 by injection molding or by pressing or gluing.

[0028] The working principle of this embodiment is: the two spline-shaped anti-bending cables 3 are respectively extended into the spline grooves 5 at both ends of the connector 1, and are in contact with the conductor 4, and then the locking bolt 2 is screwed into the locking hole 8, so that the threaded end of the locking bolt 2 presses against the outer contour of the spline-shaped anti-bending cable 3, thereby fixing the two spline-shaped anti-bending cables 3.

[0029] The beneficial effect of this embodiment is that the cable connector assembly can be applied to the connection of the spline-shaped anti-bending cable 3, is easy to use, has stable connection, and is safe and reliable. Through the adaptive structural setting of the spline groove 5 and the spline-shaped anti-bending cable 3, the cable connector assembly can prevent the cable from rotating loose, making the structural connection more stable and reliable.

[0030] Embodiment 2

[0031] The difference between this embodiment and the first embodiment is that a buffer pad 6 is fixed to the end of the locking bolt 2 .

[0032] In this embodiment, the buffer pad 6 is made of rubber material and can be fixed to the end of the threaded end of the locking bolt 2 by gluing or any other method. The rubber buffer pad 6 can prevent the bolt from damaging the insulating sheath outside the cable due to rigid extrusion.

[0033] The beneficial effect of this embodiment is that by setting the buffer pad 6, the cable can be prevented from being damaged, which is safer and more reliable, and has a longer service life. The cable connector assembly can be suitable for the connection of the spline-shaped anti-bending cable 3, which is easy to use, stable in connection, safe and reliable. Through the adaptive structural setting of the spline groove 5 and the spline-shaped anti-bending cable 3, the cable connector assembly can prevent the cable from rotating loose, making the structural connection more stable and reliable.

[0034] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily thought of by any technician familiar with the technical field within the technical scope disclosed in the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model shall be based on the protection scope of the claims.
