[0004] In the process of using the power signal line, it is necessary to deal with different devices and then different interfaces of different devices. However, the power signal line in the above application does not have a structure with multiple connectors for switching, which leads to a small range of use of the power signal line itself and great limitations in use, causing unnecessary trouble to the operator.

[0005] In view of the above problems, it is urgent to carry out innovative design based on the original power signal line. Utility Model Content

[0006] The purpose of the utility model is to provide a power signal line with multiple connectors for switching, so as to solve the problem that the structure proposed in the above-mentioned background technology does not have multiple connectors for switching, which leads to a small range of use of the power signal line body and great limitations during use, thus causing unnecessary troubles to the operator.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a power signal line with multiple connectors, comprising an external power signal line, an internal power signal line is fixedly arranged inside the external power signal line, and a connecting connector is fixedly connected to the end of the internal power signal line, and the interior of the external power signal line is filled with a protective layer;

[0008] A power signal line with multiple connectors, further comprising:

[0009] An external connection block is fixedly connected to the outer wall of the external power signal line, and a limit plate is slidably arranged inside the external connection block.

[0010] Preferably, the inner power signal lines are distributed at equal angles inside the outer power signal lines, there are three types of connecting connectors, and the protective layer is made of silicone rubber.

[0011] Preferably, the external blocks are distributed at equal angles on the surface of the external power signal line, and deep grooves are provided on the surface of the external blocks, and the external blocks correspond to the internal power signal lines one by one.

[0012] Preferably, the limiting plates are symmetrically distributed about the center of the external block, and both upper and lower sides of the limiting plates are inclined, and the limiting plates pass through the interior of the external block.

[0013] Preferably, both upper and lower sides of the limit plate are fixedly connected with sliding blocks, and the interior of the external block is provided with sliding grooves corresponding to the sliding blocks one by one.

[0014] Preferably, a connecting spring that plays an elastic reset role is fixedly connected to the surface of the slider, and the other side of the connecting spring is fixedly connected to the inner wall of the external block, and an inner groove is opened inside the external block, and the surface of the external block is in contact with the inner wall of the limit plate.

[0015] Preferably, second magnets are embedded and connected on both side inner walls of the connecting connector, and a first magnet corresponding to the second magnet is fixedly connected to the outer surface of the external power signal line, and the magnetic poles of the first magnet and the second magnet at adjacent positions are opposite.

[0016] Compared with the prior art, the beneficial effects of the utility model are: the power signal line of the multi-connector switch adopts a new structural design, the specific contents of which are as follows:

[0017] (1) The power signal line of the multi-connector switch is divided into an external power signal line and an internal power signal line, and three internal power signal lines are arranged inside the external power signal line, and the three internal power signal lines are respectively connected to a connection connector, so that the device can select a corresponding connection connector according to actual needs, thereby expanding the overall use range of the device, reducing limitations, facilitating daily use by the operator, and having a good prospect;

[0018] Furthermore, during use, two external connection blocks are always in contact with the ground, so that the external power signal line is suspended in the air, which makes the external power signal line cleaner.

[0019] (2) When the corresponding connection connector is used, the other connection connectors and the internal power signal line of the multi-connector switching power signal line are in an idle state. At this time, the internal power signal line corresponding to the idle connection connector can be bent so that the idle internal power signal line enters the corresponding external connection block;

[0020] Furthermore, when the internal power signal line enters the corresponding external block, the internal power signal line will push the limit plate to move the limit plate toward the inside of the external block. At this time, the limit plate drives the slider to slide inside the slide groove, and then the connecting spring is squeezed. After the internal power signal line enters the deep groove, the limit plate returns to its original position under the action of the connecting spring. At this time, the limit plate blocks the upper surface of the internal power signal line, so that the internal power signal line stays stably inside the external block, so that the idle internal power signal line remains stable and does not get tangled.

[0021] Furthermore, when the idle internal power signal line stays inside the external block, the idle internal power signal line is also affected by the mutual magnetic force between the first magnet and the second magnet, and then the mutual magnetic force cooperates with the limit plate to optimize stability.

DETAILED DESCRIPTION

[0029] 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.

[0030] See also Figure 1-Figure 6 The utility model provides the following technical solutions: a power signal line with multiple connectors:

[0031] Embodiment 1: By providing three internal power signal lines 2 and three connection connectors 3, the device can select the corresponding connection connector 3 according to the actual situation, thereby expanding the overall use range of the device. Figure 1 and Figure 2 As shown:

[0032] It comprises an external power signal line 1, an internal power signal line 2 is fixedly arranged inside the external power signal line 1, a connecting connector 3 is fixedly connected to the end of the internal power signal line 2, and a protective layer 4 is filled inside the external power signal line 1;

[0033] A power signal line with multiple connectors, further comprising:

[0034] The external connection block 5 is fixedly connected to the outer wall of the external power signal line 1, and a limit plate 6 is slidably arranged inside the external connection block 5.

[0035] The inner power signal line 2 is distributed at equal angles inside the outer power signal line 1 , there are three types of connecting connectors 3 , and the protective layer 4 is made of silicone rubber.

[0036] The external blocks 5 are distributed at equal angles on the surface of the external power signal line 1 , and deep grooves 7 are opened on the surface of the external blocks 5 , and the external blocks 5 correspond to the internal power signal lines 2 one by one.

[0037] The device is divided into an external power signal line 1 and an internal power signal line 2, and three internal power signal lines 2 are arranged inside the external power signal line 1. The three internal power signal lines 2 are respectively connected to a connection connector 3, so that the device can select the corresponding connection connector 3 according to actual needs, thereby expanding the overall use range of the device, reducing limitations, and facilitating daily use by the operator. During use, on the surface of the external power signal line 1, there are always two external blocks 5 in contact with the ground, so that the external power signal line 1 is suspended, and at this time the external power signal line 1 is cleaner.

[0038] Embodiment 2: Different from Embodiment 1, the idle internal power signal line 2 can be fixed by setting the limiting plate 6, so that no entanglement will occur. Figure 2-Figure 5 As shown:

[0039] The limit plate 6 is symmetrically distributed about the center of the external block 5, and the upper and lower sides of the limit plate 6 are inclined, and the limit plate 6 runs through the inside of the external block 5. The upper and lower sides of the limit plate 6 are fixedly connected with sliders 8, and the inside of the external block 5 is provided with sliding grooves 10 corresponding to the sliders 8 one by one.

[0040] The surface of the slider 8 is fixedly connected with a connecting spring 11 which plays an elastic reset role, and the other side of the connecting spring 11 is fixedly connected to the inner wall of the external block 5, and an inner groove 9 is opened inside the external block 5, and the surface of the external block 5 is in contact with the inner wall of the limit plate 6.

[0041] When the internal power signal line 2 enters the corresponding external block 5, the internal power signal line 2 will push the limit plate 6 to move the limit plate 6 toward the inside of the external block 5. At this time, the limit plate 6 drives the slider 8 to slide in the slide groove 10, and then the connecting spring 11 is squeezed. After the internal power signal line 2 enters the deep groove 7, the limit plate 6 returns to its original position under the action of the connecting spring 11. At this time, the limit plate 6 blocks the upper surface of the internal power signal line 2, so that the internal power signal line 2 stays stably inside the external block 5, so that the idle internal power signal line 2 remains stable and will not be entangled.

[0042] Embodiment 3: Different from Embodiment 2, the purpose of secondary limiting is achieved by setting the first magnet 12 and the second magnet 13, thereby improving the stability of the limited internal power signal line 2. Figure 1 and Figure 6 As shown:

[0044] When the idle internal power signal line 2 stays inside the external block 5, the idle internal power signal line 2 is also affected by the mutual magnetic force between the first magnet 12 and the second magnet 13, and then the mutual magnetic force cooperates with the limit plate 6 to optimize the stability of the idle internal power signal line 2.

[0045] The above is the working process of the entire device, and the contents not described in detail in this specification belong to the existing technology known to professional and technical personnel in this field.
