Abstract
Description
Technical Field
[0001] The utility model belongs to the field of electronic products and relates to a connector that meets the requirements of long-term positioning identification. Background Art
[0002] The push-pull self-locking connector achieves electrical connection by inserting the plug and engaging with the socket, and ensures the stability of the connection through a special locking mechanism.
[0003] In order to ensure that the push-pull self-locking connector can be plugged in smoothly, the shell of the push-pull self-locking connector is coated with a brightly colored marking layer to serve as a positioning mark. The marking layer coated on the shell of the existing push-pull self-locking connector is a paint layer directly applied on the surface of the shell. During use, it is subject to friction, scratches, oxidation, corrosion, etc., and is prone to falling off, wear, fading, etc. in a short period of time, making it difficult to use for a long time. Utility Model Content
[0004] The purpose of the utility model is to provide a connector that meets the requirements of long-term positioning identification, and solve the problem that the paint marking layer on the shell of the current push-pull self-locking connector is prone to falling off, wearing, fading, etc. in a short period of time, making it difficult to use for a long time.
[0005] The technical solutions adopted in this utility model are as follows:
[0006] A connector that meets the requirements of long-term positioning identification, including a connector shell, a groove is provided on the connector shell, and an identification layer is coated on the bottom surface inside the groove. The identification layer includes a solid color layer, the bottom surface of the solid color layer is tightly bonded to the bottom surface inside the groove, and a transparent protective layer is bonded to the top surface of the solid color layer. The bottom surface of the protective layer is bonded to the top surface of the solid color layer, and the horizontal plane where the top surface of the protective layer is located is lower than the horizontal plane where the groove notch is located.
[0007] The utility model provides a groove on the connector shell, and the identification layer is coated inside the groove. The identification layer is located lower than the surface of the connector shell. When the surface of the connector shell is rubbed, the identification layer located inside the groove has a certain distance from the connector surface. Therefore, compared with the prior art, the identification layer is not easily rubbed, thereby effectively extending its service life.
[0008] In addition, the solid color layer in the present invention is equivalent to the existing brightly colored paint layer. The present invention is based on the existing paint layer and adheres a transparent protective layer on its surface. It protects the identification layer without affecting the identification of the identification layer. This protective effect includes but is not limited to waterproof, anti-oxidation, and wear-resistant properties, further extending the service life of the solid color layer, thereby improving the service life of the entire identification layer, and solving the problem that the paint marking layer on the current push-pull self-locking connector shell is prone to falling off, wear, fading, etc. in a short period of time, making it difficult to use for a long time.
[0009] Furthermore, the protective layer is a multi-layer structure, comprising a first waterproof layer, a wear-resistant layer, an antioxidant layer, and a second waterproof layer. The first waterproof layer, the wear-resistant layer, the antioxidant layer, and the second waterproof layer are stacked sequentially in a vertical direction. The first waterproof layer is bonded to the solid color layer, the second waterproof layer is close to the groove notch, and the horizontal plane of the second waterproof layer is lower than the horizontal plane of the groove notch. The first waterproof layer, the wear-resistant layer, the antioxidant layer, and the second waterproof layer are all transparent layers.
[0010] The protective layer of the utility model is provided with a multi-layer structure, and has the properties of being waterproof, wear-resistant and anti-oxidation, and has a good protective effect on the solid color layer, so that the solid color layer is not easy to fade or fall off during use.
[0011] Furthermore, the first waterproof layer and the second waterproof layer are both polyurethane transparent waterproof coatings, which are commonly used waterproof coatings.
[0012] Furthermore, the wear-resistant layer is a wholly aromatic polyester transparent wear-resistant coating. The wholly aromatic polyester transparent wear-resistant coating is a commonly used coating with high wear resistance.
[0013] Furthermore, the anti-oxidation layer is a high-purity silicate high-temperature resistant transparent anti-oxidation heat-insulating coating. The high-purity silicate high-temperature resistant transparent anti-oxidation heat-insulating coating is an existing coating and has excellent heat insulation, anti-oxidation and anti-corrosion properties.
[0014] Furthermore, the distance between the horizontal plane where the top surface of the protective layer is located and the horizontal plane where the groove notch is located is 1 mm.
[0015] The 1mm spacing makes measurement easier without affecting the use of the connector housing, and the identification layer is not easily rubbed.
[0016] Furthermore, the depth of the groove is 2 mm. A depth of 2 mm facilitates processing and measurement.
[0017] Furthermore, the connector housing is a chrome-plated brass housing.
[0018] Furthermore, the solid color layer is a red paint solidified layer, and the bottom surface inside the groove is a rough surface after grinding. Compared with the smooth surface, the rough surface has stronger adhesion to the red paint.
[0019] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:
[0020] 1. This utility model provides a connector that meets the requirements of long-term positioning and identification. A groove is formed on the connector housing, and an identification layer is applied inside the groove. The identification layer is located below the surface of the connector housing. When the connector housing surface is rubbed, the identification layer located inside the groove is spaced a certain distance from the connector surface. Compared with the prior art, the identification layer is less susceptible to friction, effectively extending its service life.
[0021] 2. This invention is based on the existing paint layer, and a transparent protective layer is bonded to its surface. This layer protects the logo layer without affecting its markings. This protective effect includes but is not limited to waterproofing, anti-oxidation, and wear resistance, further extending the service life of the solid color layer.
[0022] 3. The protective layer in the utility model has a multi-layer structure, which has the properties of waterproof, wear-resistant and anti-oxidation, and has a good protective effect on the solid color layer, making the solid color layer not easy to fade or fall off during use.
