Specifically, as shown in fig. 1 and 2, the entire substrate 110 is rectangular, and when mounting, the substrate 110 is only directly mounted in a mounting structure such as a groove or a clip on an external device. The substrate 110 is provided with a plurality of wiring hole groups, each wiring hole group at least includes two wiring holes 111, a through hole is provided between two adjacent wiring holes 111 in the same wiring hole group, and the elastic connecting member 112 includes an elastic portion 1121 located in two adjacent wiring holes 111 and a connecting portion 1122 located in the through hole. When the end of the cable 200 is inserted into the connection hole 111, the elastic portion 1121 of the elastic connection member 112 is pushed by the end of the cable 200, the pushing force overcomes the elasticity of the elastic portion 1121 to deform the elastic portion 1121, and the elastic portion 1121 has a tendency of recovering to the original shape after being deformed and is always abutted to the cable 200 to maintain the continuity. The connecting portions 1122 at both ends of the main elastic connecting portion 1122 are in contact with the two cables 200, respectively, to complete the conduction of the two cables 200.

Further, in order to facilitate the installation, the straight type wiring terminal is further provided with a clamping portion 130. The wiring holes 111 are located on one side surface of the substrate 110, and the clamping portion 130 is located on the other side surface. When the device is installed, the clip portion 130 is only required to be clipped into the installation hole 310 of the external device. Compared with the buckle type wiring terminal, the volume is smaller, and the miniaturization design of the electric appliance is facilitated.

In one embodiment, as shown in fig. 1 and 4, at least one clamping portion 130 is disposed on the substrate 110, and the clamping portion 130 is connected to a mounting structure 300 such as a hole or a groove on an external device to fix the clamping type wire connecting terminal. For example, the clamping portion 130 may be a T-shaped protrusion, a T-shaped groove is provided on the external device, and the T-shaped clamping portion 130 slides into the T-shaped groove of the external device and then maintains a fixed connection by its own weight or a fitting relationship.

For example, two opposite elastic stopping portions 131 are arranged on one clamping portion 130, the clamping portion 130 and the elastic stopping portions 131 are triangular integrally, and the tip of the triangular structure faces the direction away from the substrate 110; the external device is provided with a mounting hole 310, because the size of the mounting hole 310 is larger than the smaller size of the triangular structure and smaller than the larger size of the triangular structure, the end of the clamping part 130 can be smoothly inserted, and when the external device is continuously inserted, the inclined plane of the elastic stopping part 131 is pressed to enable the elastic stopping part 131 to contract inwards; after the clamping portion 130 is completely inserted, the elastic stopping portion 131 moves to the other side of the mounting hole 310 and is no longer obstructed to spring outward. When the clamping portion 130 is disengaged from the mounting hole 310, the clamping portion 130 is limited from disengaging because the end surface of the elastic stopping portion 131 and the end surface of the mounting hole 310 form a stop. Other common anti-loosening structures can also be applied to the utility model, such as an elastic buckle.

The fixing groove 1131 has a V shape, and the fixing groove 1131 has a maximum size at the end of the auxiliary elastic member 113 or the elastic connection member 112 and a size gradually decreasing in a direction away from the end. When the end of the cable 200 is inserted, the end first contacts the smaller size of the fixing groove 1131, is inserted under the guiding action of the fixing groove 1131, pushes the auxiliary elastic member 113 or the elastic connecting member 112, and after the end is inserted, the fixing groove 1131 clamps and fixes the cable 200.

In one embodiment, the end of the cable is provided with a clamping structure, and the clamping structure can form a stop after the cable is inserted into the wiring hole and is conducted with the elastic connecting piece, so that the cable is prevented from being disconnected from the elastic connecting piece. For example, the cable end is tapered.

In one embodiment, the wiring hole is provided with an information identifier for assisting in wiring and avoiding misconnection and missed connection, and the information identifier can be one or any of a number identifier, a color identifier, a character identifier and a shape identifier. For example, the digital mark is used, and the wiring sleeve with the mark is sleeved at the end of the cable, so that the mark on the wiring sleeve corresponds to the digital mark on the wiring hole during wiring. For another example, the cable insulating outer layer has different colors, the wiring holes are correspondingly painted with different color marks, and the cables are connected into the wiring holes with the same color.
