[0021] 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.

[0022] See also Figure 1-4A splicable cable for a keypad comprises a wiring head 1, an auxiliary fixing assembly and a cable body 5, wherein the cable body 5 is connected to the wiring head 1 through the auxiliary fixing assembly, wherein the auxiliary fixing assembly comprises a wire frame 2, a crossbeam 3 and an elastic member, wherein the wiring head 1 is provided with the elastic member at the center of one end of the wiring body 5 close to the wiring head 1, wherein the two ends of the elastic member are respectively connected to the wiring head 1 and the crossbeam 3, wherein several groups of wire frames 2 adapted to the cable body 5 are provided below the crossbeam 3, wherein the cable body 5 is clamped with the wire frame 2, and a positioning ring 4 is further provided at one end of the wiring body 5 close to the wiring head 1, wherein the positioning ring 4 is provided between the wire frame 2 and the wiring head 1.

[0023] In actual use, the positioning ring 4 is arranged between the wire frame 2 and the terminal head 1, the cable body 5 is clamped with the wire frame 2, the end of the cable body 5 is reserved longer, and several groups of cable bodies 5 are clamped in the wire frame 2. The elastic part is driven to shrink by the crossbeam 3, and the end of the cable body 5 is completely inserted into the terminal head 1. The middle part of the cable body 5 is pulled, the elastic part is reset, and the positioning ring 4 fits the wire frame 2. At this time, the length of the cable body 5 inserted into the terminal head 1 is the same, and the cable body 5 is fixed to the terminal head 1. At this time, since the positioning ring 4 fits the wire frame 2, when the middle part of the cable body 5 is pulled, the positioning ring 4 can prevent the cable body 5 and the terminal head 1 from breaking.

[0024] In this embodiment, the wire frame 2 is elastic and is in a "gourd" shape with an opening. The opening is arranged at an end away from the crossbeam 3 to prevent the cable body 5 engaged with the wire frame 2 from being separated from the wire frame 2.

[0025] In actual use, the elastic member includes a spring 6 and a telescopic rod 7, and the spring 6 is sleeved on the telescopic rod 7. If only the spring 6 is used, the crossbeam 3 is prone to unstable support. In order to further ensure the stability of the crossbeam 3, the elastic member is arranged above the cable body 5, and a guide rod 8 is further arranged on the front and rear sides of the crossbeam 3 near one end of the corresponding terminal head 1. The terminal head 1 is provided with a guide groove adapted to the guide rod 8, and the guide rod 8 cooperates with the guide groove to ensure the stability of the movement of the crossbeam 3.
