Description
Technical Field
[0001] This utility model relates to the field of sensor technology, specifically a new energy photovoltaic sensor. Background Technology
[0002] New energy photovoltaic sensors are used in the photovoltaic field. The sensor's outer shell consists of two housings: a first housing and a second housing. The first housing has a positioning tube and multiple pins extending from the bottom. The second housing has a through hole through which the positioning tube passes and extends out of the second housing. The first and second housings are detachably connected, and their interiors form an internal cavity. Currently, the first and second housings are fixed by a snap-fit connection. This involves adding a lower flange to the first housing, with multiple through holes on the lower flange, and adding multiple protrusions to the inside of the second housing. During assembly, the lower flange of the first housing is embedded into the inside of the second housing, so that the protrusions and through holes are interlocked to fix the two housings. Although this structure can connect and fix the two housings, it still has the following shortcomings: 1. It requires adding a lower flange to the lower housing, increasing material usage and cost; 2. Due to the internal snap-fit structure, the height of the protrusions is limited to within 1.2mm due to the structural space of the inner wall of the second housing, and the engagement depth with the through holes is only 0.8-1.0mm. During vibration testing, the snap-fit phenomenon occurs when the sample comes loose. 3. When the sensor operates at a high temperature of 85℃, the 0.15mm thermal expansion of the plastic housing will increase the mating clearance between the bump and the through hole by 40%, severely weakening the connection reliability. These technical bottlenecks have become key obstacles restricting the miniaturization and cost reduction of photovoltaic sensors. Utility Model Content
[0003] The technical problem to be solved by this utility model is to provide a new energy photovoltaic sensor that uses an external structure to improve the connection strength between the first shell and the second shell, as well as the connection height and anti-detachment effect of the two, while also reducing the amount of materials and costs.
[0004] The technical solution of this utility model is to provide a new energy photovoltaic sensor with the following structure, including a first housing and a second housing. The first housing is provided with a positioning tube and multiple pins extending from the bottom. The second housing is provided with a through hole, through which the positioning tube passes and extends out of the second housing. The first housing and the second housing are detachably connected, and the interior of the two housings forms an inner cavity after connection. The first housing is characterized in that: each of the top corners of the first housing is provided with a protruding spring piece, and the spring piece is provided with a connection port. The spring piece extends downward toward the second housing. The outer wall of each top corner of the second housing is provided with a connection surface, and the connection surface is provided with a protruding positioning end. After the first housing and the second housing are assembled, the position of each spring piece corresponds one-to-one with the position of the connection surface, and the spring piece is tightly attached to the connection surface by elastic deformation, and the connection port is fitted around the positioning end.
[0005] The spring is inclined, with its free end extending outwards. The corresponding connecting surface is also inclined. After the first and second housings are assembled, the inner surface of the spring is in close contact with the connecting surface.
[0006] The connecting surface has positioning grooves distributed along the height direction on both sides, and the two sides of the spring piece have positioning protrusions. After the inner side of the spring piece is in close contact with the connecting surface, the positioning protrusions on each side are embedded in the positioning grooves on the same side.
[0007] The positioning groove has the same inclination direction as the connecting surface, and the inclination angle of the positioning groove is smaller than the inclination angle of the connecting surface.
[0008] The top of the positioning end is provided with a guide surface, and the bottom is provided with a stepped surface that is approximately perpendicular to the connecting surface.
[0009] With the above structure, this utility model has the following advantages: 1. By providing protruding spring pieces at each of the top corners of the first housing and a connecting surface on the outer wall of each top corner of the second housing, with a protruding positioning end on the connecting surface, the spring pieces are tightly attached to the connecting surface and the connecting opening is fitted around the positioning end, i.e., an external connection structure is adopted, which makes the first and second housings easier to process and reduces material usage and cost. 2. By adopting an external connection structure and increasing the height of the connecting end, the connection strength of the two housings can be met, and the engagement depth with the connecting opening can reach more than 1.2mm, avoiding the phenomenon of the invention's buckle loosening during vibration testing. 3. Through the elasticity of the spring pieces themselves, under high-temperature working conditions, the tight contact of the spring pieces can ensure the fitting clearance, further ensuring the connection strength.
[0010] As an improvement, the spring is inclined, with the free end extending outwards and the corresponding connecting surface also inclined. After the first and second housings are assembled, the inner side of the spring is in close contact with the connecting surface. The inclined spring can have better elasticity, thereby increasing the tightness with the connecting surface; at the same time, the inclined structure also has a guiding function, which facilitates assembly.
[0011] As an improvement, positioning grooves distributed along the height direction are provided on both sides of the connecting surface, and positioning protrusions are provided on both sides of the spring piece. After the inner side of the spring piece is in close contact with the connecting surface, the positioning protrusions on each side are embedded in the positioning grooves on the same side. Through the action of the positioning protrusions and positioning grooves, the connection strength between the connecting port and the positioning end is further increased.
[0012] As an improvement, the positioning groove has the same inclination direction as the connecting surface, and the inclination angle of the positioning groove is smaller than that of the connecting surface, adopting a stepped positioning and double positioning fixation.
[0013] As an improvement, the top of the positioning end is provided with a guide surface, and the bottom is provided with a stepped surface that is approximately perpendicular to the connecting surface, so that the top end has a guiding function and the bottom end has a fixing function.

[0022] The present invention will be further described below with reference to the accompanying drawings.
[0023] like Figure 1-6 As shown, a new energy photovoltaic sensor of this utility model includes a first housing 1 and a second housing 2. The first housing 1 is provided with a positioning tube 3 and multiple pins 4 extending from the bottom. The second housing 2 is provided with a through hole 5. The positioning tube 3 passes through the through hole 5 and extends out of the second housing 2. The first housing 1 and the second housing 2 are detachably connected, and the interior of the two housings forms an inner cavity.
[0024] like Figure 2 As shown, each of the top corners of the first housing 1 is provided with a protruding spring piece 6. The first housing 1 and the second housing 2 of this utility model have a roughly rectangular structure with one side being an arc surface. In this embodiment, there are four spring pieces 6, each located at one of the top corners.
[0025] The spring piece 6 is provided with a connection port 7, which is a rectangular hole that penetrates the inner and outer walls of the spring piece 6. The spring piece 6 extends downward toward the second housing 2.
[0026] Each of the top corners of the second housing 2 has a connecting surface 8 on its outer side wall. In this embodiment, there are also four connecting surfaces, and their positions correspond one-to-one with the spring piece 6.
[0027] like Figure 6 As shown, the connecting surface 8 is provided with a protruding positioning end 9; after the first housing 1 and the second housing 2 are assembled, each spring piece 6 corresponds to the position of the connecting surface 8 one by one, the spring piece 6 is tightly attached to the connecting surface 8 through elastic deformation and the connecting port 7 is sleeved around the positioning end 9.
[0028] The spring piece 6 is inclined, with its free end extending outwards, providing better elasticity and increasing the tightness of contact with the connecting surface. Simultaneously, the inclined structure also serves as a guide, facilitating assembly. The corresponding connecting surface 8 is also inclined, ensuring that the inner surface of the spring piece 6 is in close contact with the connecting surface 8 after the first housing 1 and the second housing 2 are assembled.
[0029] like Figure 5 As shown, the connecting surface 8 has positioning grooves 10 distributed along the height direction on both sides, and the spring piece 6 has positioning protrusions 11 on both sides of its edge. After the inner side of the spring piece 6 is tightly attached to the connecting surface 8, the positioning protrusions 11 on each side are embedded in the positioning grooves 10 on the same side. Through the action of the positioning protrusions and positioning grooves, the connection strength between the connecting port and the positioning end is further increased.
[0030] The positioning groove 10 has the same inclination direction as the connecting surface 8, and the inclination angle of the positioning groove 10 is smaller than the inclination angle of the connecting surface 8. A stepped positioning system with double positioning and fixation is adopted. The distance between the two positioning grooves 10 gradually decreases from the top to the bottom.
[0031] like Figure 3 As shown, the top of the positioning end 9 is provided with a guide surface 12, and the bottom is provided with a stepped surface 13 that is approximately perpendicular to the connecting surface 8. This provides a guiding function at the top and a fixing function at the bottom. The bottom of the positioning end 9 and the bottom edge of the connecting port 7 serve to provide vertical positioning.
