Description

Technical Field

[0001] The utility model relates to the technical field of current transformers, in particular to a pin assembly which is convenient for installation and positioning. Background Art

[0002] The current transformer is an electric power device based on the principle of electromagnetic induction. It is mainly used to convert high current into low voltage current for measurement, protection and control. It is an instrument that converts the large current on the primary side into the small current on the secondary side for measurement based on the principle of electromagnetic induction. When the current passes through the primary side (high current side), a magnetic flux will be generated in the iron core of the transformer. This magnetic flux passes through the secondary coil of the transformer, and according to Faraday's law of electromagnetic induction, an induced electromotive force will be generated in the secondary coil. The magnitude of the induced electromotive force is proportional to the primary current and inversely proportional to the number of turns of the secondary coil. By measuring the current in the secondary coil, the magnitude of the primary current can be obtained.

[0003] Current transformers require the use of CP pin products. The existing CP pin products require pin spacing correction and pin length trimming during back-end processing, which requires complex processes. In addition, long pins are prone to skew and deformation. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a pin assembly that is easy to install and position, which is conducive to ensuring that the CP pin spacing remains unchanged and preventing the CP pin from deforming and distorting.

[0005] The utility model adopts the following technical solutions to achieve the purpose of the utility model:

[0006] A plug assembly that is easy to install and position, characterized in that it includes: a shell assembly and a CP pin all-plastic assembly; the shell assembly includes a shell, the shell is fixedly connected to a U-shaped shell, notches are respectively provided at both ends of the U-shaped shell, positioning rods are respectively provided in the symmetrical notches, the symmetrical positioning rods are respectively fixedly connected to the U-shaped shell, the symmetrical positioning rods and the corresponding notches are respectively provided with a first slot and a second slot, and the U-shaped shell is respectively fixedly connected to the corresponding symmetrical second slots with buckles; the CP pin all-plastic assembly includes a square plate, the square plate is fixedly connected to a group of evenly distributed CP pins, the square plate is provided with symmetrical positioning grooves, and the square plate is provided with symmetrical card slots; the symmetrical notches match the square plate, the symmetrical positioning rods respectively match the corresponding positioning grooves, and the symmetrical buckles match the symmetrical card slots. The CP pins are fixed with plastic as a whole, which can fix the spacing of the CP pins, ensure the exposed length of the CP pins, and prevent the CP pins from being deformed and skewed due to being too long. By using positioning rods and positioning grooves, it is convenient for workers to install and use, and the entire CP pin all-plastic assembly is prevented from being skewed and causing defects. By using buckles and slots, a stable connection between the shell assembly and the CP needle all-plastic assembly is achieved, preventing the CP needle from floating up and causing the exposed size to exceed the tolerance.

[0007] As a further limitation of the present technical solution, the width of the notch is greater than the thickness of the square plate, which facilitates the installation of the CP pin all-plastic component.

[0008] As a further limitation of the present technical solution, the positioning rod is located at the center position in the width direction of the notch, and the positioning groove is located at the center position in the thickness direction of the square plate. This facilitates the installation of the CP pin all-plastic component in the center position.

[0009] As a further limitation of the present technical solution, the cross-section of the buckle is triangular, and the width becomes narrower as the distance from the bottom of the notch increases. When installing, the square plate presses the buckle. After the installation is in place, the buckle resumes its shape, enters the card slot, contacts the end of the card slot, and contacts the square plate to achieve stable installation.

[0010] As a further limitation of the present technical solution, the housing component and the square plate are made of plastic material.

[0011] Compared with the related technology, a pin insertion component for easy installation and positioning provided by the present utility model has the following beneficial effects:

[0012] (1) This device uses plastic to integrally fix the CP pins, which can fix the distance between the CP pins, ensure the exposed length of the CP pins, and also prevent the CP pins from being deformed and skewed due to being too long.

[0013] (2) By using the positioning rod and the positioning groove, this device is convenient for workers to install and use, and prevents the entire CP pin all-plastic component from being skewed and causing defects.

[0014] (3) By using the buckle and the card slot, this device realizes the stable connection between the housing component and the CP pin all-plastic component, and prevents floating, resulting in the exposed size of the CP pins exceeding the tolerance.

[0015] (4) After the finished product of this device comes out, there is no need to perform operations such as diagonal pin spacing and corner trimming, effectively saving labor costs, and improving production capacity and efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

Using plastic to integrally fix the CP pins can fix the spacing of the CP pins 22, ensure the exposed length of the CP pins 22, and also prevent the CP pins 22 from being deformed and skewed due to being too long. By using the positioning rods 15 and the positioning slots 24, it is convenient for workers to install and use, and prevents the entire all-plastic CP pin assembly 2 from being skewed and causing defects. By using the buckles 14 and the card slots 24, a stable connection between the housing assembly 1 and the all-plastic CP pin assembly 2 is achieved, preventing floating and causing the exposed size of the CP pins 22 to exceed the tolerance.

[0025] The width of the notch 17 is greater than the thickness of the square plate 21, which facilitates the installation of the all-plastic CP pin assembly 2.

[0027] The cross-section of the buckle 14 is triangular, and the width becomes narrower as the distance from the bottom of the notch 17 increases. During installation, the square plate 21 presses the buckle 14. After the installation is in place, the buckle 14 returns to its original shape, enters the card slot 23, contacts the end of the card slot 23, and contacts the square plate 21, achieving a stable installation.

[0028] The housing assembly 1 and the square plate 21 are made of plastic materials.
