Description

Technical Field

[0001] This utility model belongs to the technical field of cable detectors, and specifically relates to a terminal plug-in cable detector. Background Technology

[0002] PV terminals are the DC-side electrical interfaces used to connect photovoltaic modules in a photovoltaic system, typically located on equipment such as inverters or distribution cabinets. They are responsible for transmitting the DC power generated by the modules and are an important component of the system's DC side.

[0003] In the process of realizing this utility model, the inventors discovered that the prior art has at least the following problems:

[0004] The existing inverters require manual inspection of each PV terminal, which is inefficient and prone to omissions. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a terminal plug-in cable detector that solves the problem of low efficiency in manually inspecting terminals one by one by optimizing the detector structure.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A terminal plug cable detector includes a fixture body. A fixing plate and a positioning guide plate are sequentially arranged at the bottom of the fixture body. Multiple metal proximity switches and multiple micro switches are mounted on the fixing plate. A probe is provided at the bottom of each micro switch, and a spring is sleeved on the probe. The positioning guide plate is provided with multiple through holes. The bottom of the metal proximity switch passes through the through holes to detect the male terminal of the product under test, and the bottom of the probe passes through the through holes to detect the female terminal of the product under test. Multiple judgment indicator lights are provided inside the fixture body, and the multiple judgment indicator lights are electrically connected to the metal proximity switches and the micro switches respectively.

[0008] In some possible implementations, the fixing plate is provided with a first through hole that mates with the metal proximity switch, and the fixing plate is provided with a second through hole that mates with the probe rod. Both the first through hole and the second through hole penetrate the fixing plate along the thickness direction.

[0009] In some possible implementations, each of the first through holes corresponds to a through hole, and each of the second through holes corresponds to a through hole.

[0010] In some possible implementations, the spring is mounted between the bottom of the second through hole and the bottom of the probe.

[0011] In some possible implementations, the plurality of metal proximity switches and the plurality of micro switches are arranged in a matrix structure, and correspondingly, the through holes are arranged in a matrix structure on the positioning guide plate.

[0012] In some possible implementations, the plurality of metal proximity switches are arranged in multiple rows, and the plurality of micro switches are arranged in multiple rows, wherein one row of metal proximity switches is disposed between two adjacent rows of micro switches.

[0013] In some possible implementations, the top of the fixture body is provided with a housing, which covers the fixing plate.

[0014] In some possible implementations, the indicator light is mounted on the side of the housing, and a handle is provided on the top of the housing.

[0015] In some possible implementations, an L-shaped mounting plate is provided on the fixing plate, and the side of the micro switch is fixed on the L-shaped mounting plate.

[0016] In some possible implementations, the outer diameter of the probe is smaller than the outer diameter of the metal proximity switch.

[0017] One of the above technical solutions has the following beneficial effects:

[0018] This invention optimizes the detector structure by using a metal proximity switch near the male terminal of the product under test. When the bottom sensing surface of the metal proximity switch detects metal within a preset range, the switch is activated, illuminating the judgment indicator light connected to it. If no metal is detected within the preset range, the indicator light remains off. Simultaneously, a probe is used near the female terminal of the product under test. The top of the female terminal pushes up the probe, causing it to contact a microswitch and activate it, illuminating the judgment indicator light connected to it. If the female terminal is missing or not properly installed, a spring pushes the probe back to its original position, deactivating the indicator light. Compared to manual inspection, this invention's detector can simultaneously inspect multiple male and female terminals, significantly improving inspection efficiency. Attached Figure Description

[0038] If certain terms are used in the specification and claims to refer to specific components, those skilled in the art will understand that hardware manufacturers may use different names to refer to the same component. This specification and claims do not distinguish components based on differences in name, but rather on differences in function.

"Approximately" means that within an acceptable margin of error, those skilled in the art can solve the technical problem and substantially achieve the technical effect within a certain margin of error.

[0039] Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be interpreted as indicating or implying relative importance.

[0040] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0041] The present invention will be further described in detail below with reference to the accompanying drawings, but this is not intended to limit the present invention.

[0042] Because the PV terminals on existing inverters are inspected manually one by one, the inspection efficiency is low and it is easy to miss some terminals.

[0043] like Figure 1-6 As shown, the terminal plug cable detector of this utility model includes a fixture body. A fixing plate 1 and a positioning guide plate 2 are sequentially arranged at the bottom of the fixture body. Multiple metal proximity switches 3 and multiple micro switches 4 are installed on the fixing plate 1. A probe 5 is arranged at the bottom of each micro switch 4. A spring 6 is sleeved on the probe 5. Multiple through holes 21 are provided on the positioning guide plate 2. The bottom of the metal proximity switch 3 passes through the through holes 21 to detect the male terminal 7 of the product under test. The bottom of the probe 5 passes through the through holes 21 to detect the female terminal 8 of the product under test. Multiple judgment indicator lights 9 are arranged inside the fixture body. The multiple judgment indicator lights 9 are electrically connected to the metal proximity switches 3 and the micro switches 4 respectively. This invention optimizes the detector structure by using a metal proximity switch 3 near the male terminal 7 of the product under test. When the bottom sensing surface of the metal proximity switch 3 detects metal material within a preset range, the metal proximity switch 3 is activated, and the judgment indicator 9 connected to the metal proximity switch 3 illuminates. If no metal material is detected within the preset range, the judgment indicator 9 does not illuminate. Simultaneously, a probe 5 is brought near the female terminal 8 of the product under test. The top of the female terminal 8 pushes up the probe 5, which then abuts against the contact of a micro switch 4, activating the micro switch 4 and illuminating the judgment indicator 9 connected to the micro switch 4. If the female terminal 8 is missing or not properly installed, a spring 6 pushes the probe 5 back to its original position, and the judgment indicator 9 does not illuminate. Compared to manual inspection one by one, the detector of this invention can simultaneously inspect multiple male terminals 7 and female terminals 8, thus improving the efficiency of terminal inspection.

[0044] It should be noted that: the metal proximity switch 3 is a position switch in the art that can be operated without direct mechanical contact with moving parts. When a metal object approaches the sensing surface of the switch to the operating distance, the switch can be activated without mechanical contact or the application of any pressure. The micro switch 4 is a contact mechanism in the art that has a small contact interval and a quick-acting mechanism, and performs switching action with a specified stroke and a specified force. It is covered by a housing, and has a probe 5 on its outside. External mechanical force is applied to the micro switch 4 through the probe 5, causing the probe 5 to quickly connect or disconnect with the fixed contact. The positioning guide plate 2 serves as a guide, so that the male terminal 7 of the product under test approaches the metal proximity switch 3 along the through hole 21, and the female terminal 8 of the product under test pushes up the probe 5 along the through hole 21. The judgment indicator light 9 is connected to a power supply, and the switching action terminals of the metal proximity switch 3 and the micro switch 4 are respectively located between the power supply and the judgment indicator light 9.

[0045] In the terminal plug-in cable detector according to this utility model, a first through hole 11 is provided on the fixing plate 1 to cooperate with a metal proximity switch 3, and a second through hole 12 is provided on the fixing plate 1 to cooperate with a probe 5. Both the first through hole 11 and the second through hole 12 penetrate the fixing plate 1 along the thickness direction. Specifically, the first through hole 11 allows the metal proximity switch 3 to pass through the fixing plate 1 and approach the male terminal 7, and the second through hole 12 allows the probe 5 to pass through the fixing plate 1 and contact the female terminal 8. The size of the first through hole 11 is larger than that of the second through hole 12. The order of the first through hole 11 and the second through hole 12 is the same as the order of the metal proximity switch 3 and the probe 5. Each first through hole 11 is connected to a through hole 21, and each second through hole 12 is connected to a through hole 21, so that the male terminal 7 of the product under test approaches the metal proximity switch 3 along the through hole 21, and the female terminal 8 of the product under test pushes up the probe 5 along the through hole 21.

[0046] In the terminal plug cable detector according to this utility model, a spring 6 is installed between the bottom of the second through hole 12 and the bottom of the probe 5. Specifically, when the top of the female terminal 8 pushes up the probe 5, the spring 6 is in a compressed state. When the female terminal 8 is missing or not installed in place, the spring 6 pushes the probe 5 back to its original position, thus the spring 6 serves to reset the probe 5.

[0047] In the terminal plug-in cable detector according to this utility model, multiple metal proximity switches 3 and multiple micro switches 4 are arranged in a matrix structure, and correspondingly, through holes 21 are arranged in a matrix structure on the positioning guide plate 2. Specifically, there are six metal proximity switches 3 and six micro switches 4. The matrix arrangement of the metal proximity switches 3 and micro switches 4 helps to improve the space utilization of the bottom of the fixture body, thereby improving the inspection efficiency of the terminals.

[0048] In the terminal plug-in cable detector according to this utility model, multiple metal proximity switches 3 are arranged in multiple rows, and multiple micro switches 4 are arranged in multiple rows, with one row of metal proximity switches 3 arranged between two adjacent rows of micro switches 4. Specifically, six metal proximity switches 3 are arranged in two rows, with three metal proximity switches 3 in each row, and six micro switches 4 are arranged in two rows, with three micro switches 4 in each row, allowing for the simultaneous inspection of 12 PV terminals.

[0049] In the terminal plug-in cable detector according to this utility model, a housing 10 is provided on the top of the fixture body, and the housing 10 covers the fixing plate 1. Specifically, the housing 10 serves to protect each switch. The housing 10 is roughly square in shape, and the housing 10 and the fixing plate 1 form a cavity, in which each switch is installed.

[0050] In the terminal plug-in cable detector according to this utility model, the judgment indicator light 9 is installed on the side of the housing 10 for easy observation by the operator, and the top of the housing 10 is provided with a handle 101 for easy movement of the detector by the operator.

[0051] In the terminal plug-in cable detector according to this utility model, an L-shaped mounting plate 20 is provided on the fixing plate 1, and the side of the micro switch 4 is fixed on the L-shaped mounting plate 20. Specifically, one side of the L-shaped mounting plate 20 is fixed to the fixing plate 1 by screws, and the other side of the L-shaped mounting plate 20 is perpendicular to the fixing plate 1. This side fixes the side of the micro switch 4 to prevent the micro switch 4 from shifting or shaking.

[0052] In the terminal plug-in cable detector according to this utility model, the outer diameter of the probe 5 is smaller than the outer diameter of the metal proximity switch 3, which matches the shape of the PV terminal. However, this utility model is not limited to this and can be adjusted according to the actual shape and size of the PV terminal.

[0053] The working principle of this utility model is as follows:

[0054] This invention optimizes the detector structure by using a metal proximity switch 3 near the male terminal 7 of the product under test. When the bottom sensing surface of the metal proximity switch 3 detects metal material within a preset range, the metal proximity switch 3 is activated, and the judgment indicator 9 connected to the metal proximity switch 3 illuminates. If no metal material is detected within the preset range, the judgment indicator 9 does not illuminate. Simultaneously, a probe 5 is brought near the female terminal 8 of the product under test. The top of the female terminal 8 pushes up the probe 5, which then abuts against the contact of a micro switch 4, activating the micro switch 4 and illuminating the judgment indicator 9 connected to the micro switch 4. If the female terminal 8 is missing or not properly installed, a spring 6 pushes the probe 5 back to its original position, and the judgment indicator 9 does not illuminate. Compared to manual inspection one by one, the detector of this invention can simultaneously inspect multiple male terminals 7 and female terminals 8, thus improving the efficiency of terminal inspection.

[0055] Based on the disclosure and teachings of the above specification, those skilled in the art can make changes and modifications to the above embodiments. Therefore, this utility model is not limited to the specific embodiments described above, and any obvious improvements, substitutions, or modifications made by those skilled in the art based on this utility model are within the protection scope of this utility model. Furthermore, although some specific terms are used in this specification, these terms are only for convenience of explanation and do not constitute any limitation on this utility model.
