Description

Technical Field

[0001] The present invention relates to the technical field of connectors, and in particular to a distributor. Background Art

[0002] A distributor is a device used for current distribution or signal distribution. It can divide one current or signal into multiple paths. Therefore, there will be multiple connection ports on the distributor, one used as the input port for current or signal, and the others used as the output ports for current or signal to deliver current or signals to other devices or other distributors.

[0003] The connection ports of existing distributors are generally arranged on the same side of the device, and the cables have a certain thickness. In order to facilitate installation, the connection ports are usually arranged in a line. Therefore, the existing distributors are usually large and long, which is not conducive to carrying and installation, and also increases the manufacturing cost.

[0004] Moreover, during use, some devices are usually installed at a higher position than the distributor. When a traditional distributor is connected to the device, the cable needs to be connected from the lower end of the distributor and then bent upward to connect to the device at a higher position. This connection method will lead to inconvenient installation on the one hand, and on the other hand, long-term use will cause damage to the cable.

[0005] In traditional distributors, pins need to be connected to the circuit board one by one. Since the pins are generally small in size, the technical requirements for operators are high when assembling the pins, and the accuracy of the pin assembly cannot be guaranteed. There is a situation where the pins are assembled crooked, which leads to low product yield and low assembly efficiency.

[0006] Traditional distributors generally adopt an integrated design, that is, the distributor is fixed and installed by directly opening mounting holes on the distributor housing. This installation method is not only inconvenient and lacks installation reliability, but also troublesome to disassemble and replace.

[0051] This embodiment provides a distributor, such as Figure 1 and Figure 2 As shown, it comprises a main body 1 and a base 2 , and the main body 1 is installed on the base 2 .

[0052] like Figure 3 As shown, the base 2 includes a fixing portion 21, a limiting portion 22 and a clamping portion 23, wherein the limiting portion 22 and the clamping portion 23 are respectively arranged on the same side of the fixing portion 21. A spatial coordinate system is now defined, wherein the length direction of the fixing portion 21 is the x-axis direction, and the width direction of the fixing portion 21 is the y-axis direction. The length direction of the clamping portion 23 is consistent with the x-axis direction, and the limiting portions 22 are respectively symmetrically arranged on both sides of the clamping portion 23 in the x-axis direction, and a clamping groove 221 is provided on the limiting portion 22. The fixing portion 21 is arc-shaped, and the limiting portion 22 and the clamping portion 23 are respectively arranged on one side of the fixing portion 21 in the negative direction of the z-axis, and the two ends of the fixing portion 21 in the length direction are respectively bent toward the positive direction of the z-axis. The fixing portion 21 is respectively provided with first through holes 211 at positions close to the two ends in the length direction. Preferably, the first through hole 211 is a long through hole, and the length direction of the first through hole 211 is consistent with the length direction of the fixing portion 21. The two ends of the base 2 can be fixed by the first through hole 211, which can effectively prevent the base 2 from rotating after being fixed. The first through hole 211 is designed to be long and can adapt to different installation positions, such as columns of different diameters, and can also not require high installation accuracy to a certain extent, thereby improving the convenience of installing the base 2.

[0053] The fixing portion 21 is also provided with a second through hole 212, which is located on one side of the clamping portion 23 in the positive direction of the y-axis. The second through hole 212 is preferably a round hole, which can further ensure the installation reliability of the base 2 and prevent the dispenser from tilting after the dispenser body 1 is installed.

[0054] In a further embodiment, the limiting portion 22 includes a first side plate 222, a second side plate 223, a first limiting plate 224, a second limiting plate 225, a third limiting plate 226 and a bottom plate 227. Figure 3 As shown, the first side plate 222 and the second side plate 223 are arranged in parallel and spaced apart, the length direction of the first side plate 222 and the length direction of the second side plate 223 are respectively consistent with the y-axis direction, and the width direction of the first side plate 222 and the width direction of the second side plate 223 are respectively consistent with the z-axis direction. The first side plate 222 and the second side plate 223 are respectively connected to the fixing portion 21. The first limiting plate 224 is arranged between the first side plate 222 and the second side plate 223, the length direction of the first limiting plate 224 is consistent with the y-axis direction, the width direction of the first limiting plate 224 is consistent with the x-axis direction, and the first limiting plate 224 is respectively connected to the first side plate 222 and the second side plate 223. The second limiting plate 225 and the third limiting plate 226 are respectively arranged in parallel and at intervals on the side of the first limiting plate 224 in the negative direction of the z-axis, the second limiting plate 225 is connected to the first side plate 222, the third limiting plate 226 is connected to the second side plate 223, and there is a gap between the second limiting plate 225 and the third limiting plate 226. The length direction of the bottom plate 227 is consistent with the x-axis direction, and the width direction of the bottom plate 227 is consistent with the z-axis direction. The bottom plate 227 is located on the side of the clamping portion 23 in the negative direction of the y-axis. The first side plate 222, the second side plate 223, the first limiting plate 224, the second limiting plate 225 and the third limiting plate 226 are respectively connected to the bottom plate 227 to form a T-shaped clamping groove 221.

[0055] The bottom plate 227 has a support portion 228 extending outwardly along the negative direction of the z-axis. When the dispenser body 1 is mounted on the base 2, the support portion 228 contacts the bottom of the dispenser body 1. Figure 2 As shown, it plays the role of supporting the dispenser body 1 and can effectively prevent the dispenser body 1 from being deflected.

[0056] The lengths of the first side plate 222 and the second side plate 223 are respectively greater than the lengths of the first limiting plate 224, the second limiting plate 225 and the third limiting plate 226, that is, the first side plate 222 and the second side plate 223 are higher than the first limiting plate 224, the second limiting plate 225 and the third limiting plate 226. The first side plate 222 and the second side plate 223 are respectively provided with cut corners, that is, the higher parts of the first side plate 222 and the second side plate 223 are inclined, and this structural design can play a guiding role when installing the dispenser body 1, so that the dispenser body 1 can be smoothly guided to the accurate installation position.

[0057] The clamping part 23 is connected to the side plates of the two limiting parts 22 at both ends of the x-axis, and the clamping part 23 is connected to the fixing part 21 at one end in the positive direction of the z-axis. The width direction of the clamping part 23 is consistent with the z-axis direction. Or the clamping part 23 can be slightly tilted, that is, the end of the clamping part 23 in the negative direction of the z-axis is tilted toward the negative direction of the y-axis at a set angle, which can improve the reliability of the clamping to a certain extent. A cut angle is provided at the corner of one end of the clamping part 23 in the negative direction of the z-axis, and by setting the cut angle, it can be ensured that the clamping is smoother.

[0058] In a further embodiment, the fixing portion 21 is further provided with a plurality of reinforcing ribs, such as Figure 3 and Figure 4For example, a plurality of first reinforcing ribs 24 are provided on one side of the fixing portion 21 in the negative direction of the z-axis, the length direction of the first reinforcing rib 24 is consistent with the x-axis direction, the width direction of the first reinforcing rib 24 is consistent with the z-axis direction, and the plurality of first reinforcing ribs 24 are respectively located on both sides of the two limiting portions 22 in the x-axis direction, and the first reinforcing ribs 24 are connected to the side plates of the corresponding limiting portions 22. The first reinforcing ribs 24 can increase the strength of the fixing portion 21 of the base 2, making the base 2 stronger and more securely installed. For another example, a plurality of second reinforcing ribs 25 are arranged between the first side plate 222 and the second side plate 223, the length direction of the second reinforcing rib 25 is consistent with the y-axis direction, the width direction of the second reinforcing rib 25 is consistent with the z-axis direction, the second reinforcing rib 25 is respectively connected to the fixing portion 21, the first limiting plate 224 and the bottom plate 227, the length of the second reinforcing rib 25 is greater than the first limiting plate 224, and the second reinforcing rib 25 is provided with a cut angle. By adding the second reinforcing rib 25, on the one hand, the stability of the base 2 can be improved, and on the other hand, it can also play a guiding role, so that the dispenser body 1 can be smoothly installed on the base 2. For another example, a plurality of third reinforcing ribs 26 are provided between the clamping portion 23 and the bottom plate 227, the length direction of the third reinforcing ribs 26 is consistent with the y-axis direction, the width direction of the third reinforcing ribs 26 is consistent with the z-axis direction, and the third reinforcing ribs 26 are connected to the clamping portion 23 and the bottom plate 227, respectively. By adding the third reinforcing ribs 26, the clamping portion 23 can be supported, and the strength of the clamping portion 23 can be increased. For another example, a plurality of fourth reinforcing ribs 27 are provided on one side of the bottom plate 227 in the negative direction of the y-axis, the length direction of the fourth reinforcing ribs 27 is consistent with the z-axis direction, and the width direction of the third reinforcing ribs 26 is consistent with the y-axis direction.
