Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of electrical equipment, and in particular to a method for determining parameters of a cable connector and the cable connector. Background Art
[0002] The three-phase copper busbar is a common cable connector, usually made of pure copper or copper alloy with high conductivity, with excellent electrical conductivity and mechanical strength, and is widely used in large-scale mechanical equipment, automated production lines, motors and other industrial equipment. The three-phase copper busbar includes conductors, insulating materials, supporting materials and terminals. The insulating materials are used to isolate the conductors and supporting materials to prevent safety hazards such as short circuits and leakage. They are usually made of flame-retardant plastics or resins. Plastic or resin materials are easily deformed due to the large temperature difference between the inside and outside during high-temperature molding. In addition, the three-phase copper busbar product structure is long strips, with metal inserts embedded in sections. It is distorted due to factors such as shrinkage and heat conduction, causing the final product to warp and deform, and the flatness of the reference surface is poor. To address the above issues, the methods currently used include optimizing molding parameters based on mold flow analysis, separately setting the front and rear mold temperature control systems, and creating temperature differences. However, this method does not have a significant improvement effect and affects the appearance. Another method is to make a shaping tool, and load the three-phase copper busbar product into the tooling for anti-warping shaping after it is ejected from the mold. Although this method can improve flatness and meet requirements, it has a high risk of internal stress. As the ambient temperature rises, the product will return to its pre-shaping shape and cannot meet the product usage scenarios. Summary of the invention

[0052] Step 12, obtaining deformation data of the plastic part of the cable connector during the heating and shaping process according to the basic parameters of the cable connector;
[0053] Step 13, obtaining plastic part compensation data of the cable connector according to the deformation data;

[0055] Step 15, obtaining the preparation parameters of the cable connector according to the plastic component compensation data and the copper busbar compensation data.
[0056] In this embodiment, the basic parameter information of the cable connector may include but is not limited to: plastic part material data, plastic part size data, copper busbar size data and copper busbar installation position data; after obtaining the basic parameters of the cable connector, analyze the temperature distribution and deformation of the plastic part during the heating process, including the expansion amount and shape change of each part, so as to obtain the deformation amount of the plastic part; according to the deformation law and trend of the plastic part, calculate the compensation amount that needs to be added in the design and manufacturing process, including the size of each part of the plastic part that needs to be adjusted, and the additional material or structure that needs to be added to offset the deformation; since the deformation of the plastic part will affect the position and shape of the copper busbar installed thereon, it is necessary to calculate the compensation data of the copper busbar based on the compensation data of the plastic part, and the compensation data of the copper busbar includes the bending or twisting adjustment that needs to be made and the adjustment of the position of the component on the copper busbar; the plastic part compensation data and the copper busbar compensation data are combined to form a complete cable connector preparation parameter, where the preparation parameters may include: plastic part material data, plastic part size data, copper busbar size data and copper busbar installation position data; these preparation parameters will be used to guide the actual manufacturing process of the cable connector to ensure that the quality and performance of the final product meet the design requirements.
[0057] The parameter determination method of the cable connector proposed in the above embodiment of the present invention obtains deformation deviation parameters by analyzing the deformation of the three-phase copper busbar product, modifies the copper busbar mold according to the deformation deviation parameters, performs pre-deformation design and glue compensation, so that the product flatness meets the tolerance requirements and improves the product quality.
[0058] In an optional embodiment of the present invention, step 11 may include:
[0059] Step 111, obtaining basic parameters of the cable connector according to the simulation model of the cable connector, wherein the basic parameters include at least one of plastic component material data, plastic component size data, copper busbar size data, and copper busbar installation position data.
[0060] In this embodiment, the simulation model of the cable connector is created based on computer-aided design software to simulate the actual structure, material and performance of the cable connector so as to perform detailed evaluation and optimization before the design and manufacturing stages; by reading and analyzing the simulation model of the cable connector, basic parameters of the cable connector can be obtained, including plastic material data, plastic size data, copper busbar size data and copper busbar installation position data, etc.;
[0061] The cable connector is mainly made of plastic parts, and other components such as copper busbars are installed with plastic parts as the main body; the plastic part material data refers to the type of material used to determine the plastic part, such as polypropylene (PP), polycarbonate (PC), nylon (PA), etc. The plastic part size data includes the length, width, height and detailed dimensions of each part of the plastic part; similarly, by reading and analyzing the simulation model of the cable connector, the size data of the copper busbar can also be obtained, including the thickness, width, length and the exact installation position of the copper busbar in the cable connector.
[0062] In an optional embodiment of the present invention, step 12 may include:
[0063] Step 121, according to
[0064] δ = k∙(T max –T0)∙p t ∙t (1)
[0065] Obtaining deformation data of the plastic part of the cable connector during the heating and shaping process;
[0066] Among them, δ is the deformation data, k is the shrinkage coefficient of the plastic part, T max is the highest temperature of the plastic part during the molding process, T0 is the starting temperature of the plastic part during the molding process, and p t is the heating time coefficient of the plastic part during the molding process, and t is the heating time.
[0067] In this embodiment, the deformation data of the plastic part during the heating and shaping process is related to the shrinkage coefficient of the plastic part, the highest temperature and the starting temperature of the plastic part during the shaping process, and the heating time of the plastic part during the shaping process; wherein the shrinkage coefficient of the plastic part may also be referred to as the shrinkage rate of the plastic part, which is related to the material of the plastic part. Plastic parts made of different materials have different degrees of deformation due to heat. Generally, ABS plastic is 0.4% to 0.9%, PC plastic is 0.2% to 0.6%, PE plastic is 1.5% to 3.0%, PP plastic is 1.2% to 2.5%, and PVC plastic is 0.3% to 1.0%; the heating time coefficient p of the plastic part during the shaping process is 0.4% to 0.9%, PC plastic is 0.2% to 0.6%, PE plastic is 1.5% to 3.0%, PP plastic is 1.2% to 2.5%, and PVC plastic is 0.3% to 1.0%. tIt is related to the material, heating temperature and heating time of the plastic part. Generally speaking, for the same material of plastic parts, the deformation of the plastic parts during the heating and shaping process is proportional to the heating temperature and heating time. Therefore, this coefficient can be obtained by accurately measuring the deformation of the plastic parts during the heating and shaping process. t= δ´ / k∙(T max –T0)∙t, δ´ is the measured value of the deformation of the plastic part; by measuring the deformation of the plastic part during the heating and shaping process multiple times, multiple heating time coefficients can be obtained, and the heating time coefficient table can be obtained by statistically analyzing the multiple heating time coefficients; when calculating the deformation data of the plastic part, p can be quickly obtained by querying the heating time coefficient table. t The specific value of .

[0069] Step 131, according to
[0070] Δl=δ∙L (2)
[0071] Obtaining plastic part compensation data of the cable connector;
[0072] Wherein, Δl is the plastic component compensation data, and L is the shortest distance from the center point of the end surface of the steel sleeve 5 in the middle of the cable connector to the end of the cable connector.
[0073] In this embodiment, a plane passing through the center point of the end face of the steel sleeve 5 in the middle of the cable connector and perpendicular to the end face of the cable connector in the simulation model of the cable connector is taken as a reference plane, then L is the shortest distance from the center point of the end face of the steel sleeve 5 in the middle of the cable connector to the end of the cable connector; in this example, the cable connector has two ends, so the plastic part compensation data Δl is also divided into a first end compensation data Δl1 and a second end compensation data Δl2, wherein Δl1=δ∙L1, Δl2=δ∙L2, L1 is the shortest distance from the center point of the end face of the steel sleeve 5 in the middle of the cable connector to the first end of the cable connector, and L2 is the shortest distance from the center point of the end face of the steel sleeve 5 in the middle of the cable connector to the second end of the cable connector.

[0078] Step 142, according to
[0079] (4)

[0081] in, is the horizontal angle compensation data of the i-th copper busbar, i=1, 2, ..., n, is the offset coefficient of the ith copper busbar, is the shortest distance from the ith copper busbar to the end face of the cable connector, is the compensation data of the ith copper busbar overlap hole, The shortest distance from the center point of the i-th copper busbar lap hole to the end face of the cable connector.
[0082] In this embodiment, since the copper bar is fixedly installed in the plastic part, when the plastic part is deformed during the heating and shaping process, the final angle and position of the copper bar when the cable connector is formed will also be found to be offset, so it is necessary to compensate for the angle and position offset of the copper bar; the offset of the copper bar is mainly affected by its placement position, and since the deformation of the cable connector during the heating and shaping process is mainly bending at both ends, the closer the copper bar is to the center point of the end face of the steel sleeve 5 in the middle of the cable connector, the smaller the offset, and the farther the copper bar is from the center point of the end face of the steel sleeve 5 in the middle of the cable connector, the larger the offset, so the offset coefficient corresponding to each copper bar is are different, the offset coefficient It can also be obtained by accurately measuring the deformation of plastic parts during the heating and shaping process, including:
[0083] (5)
[0084] in, is the measured value of the horizontal angle offset of the i-th copper bar; by measuring the horizontal angle offset of the copper bar during the deformation of the plastic part multiple times, multiple offset coefficients can be obtained, and the multiple offset coefficients can be counted to obtain an offset coefficient table; when calculating the horizontal angle compensation data of the copper bar, the offset coefficient table can be quickly obtained The specific value of .
[0085] In an optional embodiment of the present invention, step 15 may include:
[0086] Step 151: adjusting basic parameters of the cable connector according to the plastic component compensation data and the copper busbar compensation data to obtain preparation parameters of the cable connector.
[0087] In this embodiment, the collected plastic part compensation data and copper busbar compensation data are analyzed in detail, including determining the size and direction of the deviation; based on the analysis results, the basic parameters of the cable connector are adjusted, including adjusting the size, shape and other parameters of the plastic part, and adjusting the size, position and other parameters of the copper busbar, so that the actual performance of the connector is as close to the design expectations as possible; after adjusting the basic parameters, the performance of the connector is tested and verified again; if the adjusted connector performance meets the expected requirements, the adjusted parameters can be determined as the preparation parameters of the cable connector, and the preparation parameters include: plastic part material data, plastic part size data, copper busbar size data and copper busbar installation position data.

[0092] The product is molded under high mold temperature conditions, and the temperature difference between the inside and outside is too large after production, resulting in shrinkage and deformation; the product structure is long and strip-shaped, and metal inserts are embedded in sections, which are affected by shrinkage, heat conduction and many other factors. The molding parameters are optimized according to mold flow analysis, and the front and rear mold temperature control systems are set separately to create temperature differences; shaping tooling is made, and the product is loaded into the tooling for anti-warping and shaping after being ejected from the mold; combined with mold flow software analysis and the above-mentioned optimization results, the pre-deformation design of the product is modified, and the plastic and hardware copper bar molds are modified separately to make the product achieve the expected effect and the flatness meets the tolerance requirements;
