Description

Technical Field

[0001] This utility model relates to the field of electrical connector technology, and in particular to an electrical connector housing measuring device. Background Technology

[0002] Electrical connectors are components used to connect electrical circuits, enabling reliable transmission of electrical signals or power at points where circuits are broken. They are widely used in electronic equipment, power systems, and communication devices. The dimensional accuracy of their housings directly affects the mechanical assemblability, electrical performance, and environmental reliability of the products. Currently, most electrical connector housings on the market are rectangular or circular. During the manufacturing process, the housings must meet strict tolerance requirements (usually within ±0.05mm) to ensure compatibility with mating components (such as PCBs and sealing rings). If the dimensions are out of tolerance, it may lead to assembly failure, poor sealing, and reduced electromagnetic shielding performance. Therefore, it is necessary to measure and inspect the dimensions of the housings during the production process.

[0003] When measuring the dimensions of a shell, it can be divided into measuring the surface dimensions of the shell and measuring the internal structural dimensions. When conducting preliminary quality inspection of the shell, the surface dimensions of the shells are often measured in batches. However, at present, most shell inspections are carried out by measuring with calipers and coordinate measuring machines. This measurement method relies on manual hand-held measuring tools to measure the shells one by one. This is not only time-consuming and labor-intensive, but also has a large human error, making it difficult to meet the needs of mass production. Utility Model Content

[0004] To overcome the shortcomings of the prior art, this utility model discloses an electrical connector housing measuring device. This utility model not only satisfies the preliminary measurement of the housing size and realizes the preliminary quality inspection of the housing, but also greatly reduces the operation difficulty for operators and improves the inspection efficiency.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An electrical connector housing measuring device includes a bracket with a chain conveyor belt for horizontal transport of the housing. Each chain plate in the chain conveyor belt has a clamping mechanism on its upper surface for elastically clamping and limiting the housing. The clamping mechanism includes two mirror-symmetrical clamping members with adjustable spacing. Each clamping member includes a base plate, a side plate, an elastic telescopic rod, and a movable plate. The base plate is detachably connected to the chain plate in the chain conveyor belt. One side of the upper surface of the base plate is provided with a side plate perpendicular to the base plate. The side of the side plate facing away from the base plate is provided with an elastic telescopic rod perpendicular to the side plate. The movable end of the elastic telescopic rod is provided with a movable plate parallel to the side plate. The bracket also has a mounting frame located above the chain conveyor belt. The mounting frame is equipped with a laser measuring device for cooperating with the chain conveyor belt and for measuring the housing one by one and comparing and judging the measurement data.

[0007] Furthermore, the laser measurement equipment includes a red laser generator for emitting a high-precision laser beam, a CMOS camera for capturing the reflected light spot of the laser on the surface of the housing and generating point cloud data, and an industrial control computer for processing, comparing and judging the measurement data.

[0008] Furthermore, the mounting frame has a U-shaped structure, with the two side columns of the mounting frame fixedly connected to the two sides of the support. The crossbeam of the mounting frame is set vertically and vertically with the chain conveyor belt. The red laser generator and CMOS camera are installed on the lower part of the crossbeam of the mounting frame, and the industrial control computer is installed on the outside of the column of the mounting frame.

[0009] Furthermore, the upper surface of the chain plate in the chain plate conveyor belt is provided with several polygonal mounting holes arranged at intervals along the length of the chain plate, and the lower surface of the bottom plate is provided with insertion rods that are compatible with the polygonal mounting holes.

[0010] Furthermore, the upper side of the movable plate is provided with an inclined surface that slopes toward the side plate.

[0011] Furthermore, a light-absorbing plate is provided along the inclined surface, which is parallel to and corresponds to the base plate and is used to reduce laser reflection.

[0012] Furthermore, a rubber strip is provided on the side of the movable plate facing away from the side plate for elastically clamping the housing.

[0013] Furthermore, the movable plate has several grooves spaced from top to bottom on the side facing away from the side plate, with open ends, and a mounting rod adapted to the grooves is provided on one side of the rubber strip.

[0014] Compared with the prior art, the beneficial effects of this utility model are: by combining the chain plate conveyor belt with the laser measurement equipment, the upper part of most electrical connector housings (such as rectangular or circular housings) can be laser measured one by one during the horizontal transport process. This method not only meets most of the conventional inspection requirements of the housings and provides strong support for the high-quality processing and production of the housings, but also greatly reduces the difficulty of operation for workers and improves the inspection efficiency.

[0015] By setting up a clamping mechanism, the housing can be clamped and limited horizontally and stably, providing strong support for subsequent measurements of the upper part of the housing;

[0016] By setting a detachable base plate and an elastic telescopic rod, the distance between the two clamping parts can be adjusted to meet the clamping and limiting requirements of housings of different sizes and specifications.

[0017] By setting up a light-absorbing plate, stray laser light can be absorbed and reflection interference reduced during laser scanning measurement, effectively improving the accuracy of the measurement.

[0018] By setting rubber strips, not only can the two sides of the shell be stably matched and limited, but wear on the shell is also reduced.

[0019] This invention allows for the measurement of the upper surface of the housing during the conveying process, which not only satisfies the preliminary measurement of the housing's dimensions and the preliminary quality inspection of the housing, but also improves efficiency by more than 80% while ensuring inspection accuracy and significantly reducing the difficulty of operation, making it suitable for quality control in large-scale production.

In the description, it should be understood that if there are terms such as "upper", "lower", "front", "rear", "left", "right" indicating the orientation or positional relationship, they are only corresponding to the drawings of this utility model for the convenience of describing this utility model, and do not indicate or imply that the device or element referred to must have a specific orientation.

[0025] Please refer to the instruction manual appendix. Figure 1-3 This utility model provides a technical solution:

[0026] Example 1: An electrical connector housing measuring device includes a bracket 1. The bracket 1 is equipped with a chain conveyor belt 4 for horizontal transport of the housing. The chain conveyor belt 4 includes chain plates, a transmission chain, a drive motor, and a tensioning device. Each chain plate in the chain conveyor belt 4 has a clamping mechanism on its upper surface for elastically clamping and limiting the housing. Specifically, the clamping mechanism includes two mirror-symmetrically arranged clamping members 6. Each clamping member 6 includes a base plate 8, a side plate 9, an elastic telescopic rod 10, and a movable plate 13. The base plate 8 is detachably connected to the chain plates in the chain conveyor belt 4. One side of the upper surface of the base plate 8 has a side plate 9 perpendicular to the base plate 8. The side of the side plate 9 facing away from the base plate 8 has an elastic telescopic rod 10 perpendicular to the side plate 9. The movable end of the elastic telescopic rod 10 has a movable plate 13 parallel to the side plate 9. The bracket 1 is also equipped with a mounting frame 2 located on the upper part of the chain conveyor belt 4. Mounting bracket 2 is equipped with a laser measuring device 3 for cooperating with the chain conveyor belt 4 and for measuring the shell one by one and comparing the measurement data. Specifically, the laser measuring device 3 includes a red laser generator for emitting a high-precision laser beam, a CMOS camera for capturing the reflected light spot of the laser on the surface of the shell and generating point cloud data, and an industrial control computer for processing, comparing and judging the measurement data. Mounting bracket 2 has a U-shaped structure. The two side columns of mounting bracket 2 are fixedly connected to the two sides of bracket 1 respectively. The crossbeam of mounting bracket 2 is set vertically and vertically with the chain conveyor belt 4. The red laser generator and CMOS camera are installed on the lower part of the crossbeam of mounting bracket 2. The industrial control computer is installed on the outside of the column of mounting bracket 2. In order to facilitate the staff to understand the measurement data of the shell conveniently and efficiently, the industrial control computer also includes an industrial control computer touch control screen. The measurement data can be read in time by using the industrial control computer touch control screen.

[0027] When measuring the dimensions of a standard electrical connector housing, the housings are placed one by one into the clamping mechanism on the inner chain plate of the chain conveyor belt 4. After the housings are horizontally clamped and fixed by two clamping parts 6, they are transported by the chain conveyor belt 4. The red laser generator in the laser measuring device 3 emits a high-precision laser beam onto the upper surface of the housing. The CMOS camera captures the reflected light spot on the housing surface and generates point cloud data. After receiving the point cloud data, the industrial control computer compares it with the pre-stored CAD model and outputs a dimension report. By observing the dimension report, the staff can efficiently understand the dimension inspection of the upper surface of the housing (flatness, hole position, etc.) and the identification of some defects, thereby completing the routine dimension measurement and inspection of the housing and conveniently and efficiently rejecting unqualified housings.

[0028] In Example 2, to meet the horizontal clamping and limiting requirements of shells of different sizes, the upper surface of the chain plate in the chain conveyor belt 4 is provided with several polygonal mounting holes 5 arranged in an orderly manner along the length of the chain plate. The lower surface of the base plate 8 is provided with insertion rods 12 that are compatible with the polygonal mounting holes 5. The distance between the two clamping parts 6 can be adjusted by using the detachable base plate 8. With the addition of the elastic telescopic rod 10, the shell can be effectively clamped and limited. In order to enable the operator to easily clamp and fix the shell, the upper side of the movable plate 13 is provided with an inclined surface 11 that is inclined towards the side plate 9. The inclined surface 11 can not only reduce the friction between the movable plate 13 and the shell, but also guide the shell to be easily and efficiently placed between the two movable plates 13.

[0029] In the third embodiment, during the laser measurement process, since the clamping member 6 is clamped on both sides of the housing, the laser measuring device 3 will inevitably irradiate the clamping member 6 with laser light. In order to avoid the clamping member 6 affecting the measurement of the housing, a light-absorbing plate 7 is provided on the upper edge of the inclined surface 11, which is parallel to and corresponding to the base plate 8 and is used to reduce laser reflection. Specifically, the light-absorbing plate 7 is made of matte black nylon or anodized aluminum. The light-absorbing plate 7 can effectively shield the movable plate 13, the elastic telescopic rod 10 and the base plate 8.

[0030] In Example 4, due to the different shell structures, if the two sides are curved or irregular planes, the movable plate 13 cannot stably clamp the shell. In order to enable the clamping member 6 to stably clamp and limit the shell, the movable plate 13 is provided with a rubber strip 15 for elastic clamping and engaging the shell on the side facing away from the side plate 9. Specifically, the movable plate 13 is provided with several grooves 16 spaced from top to bottom and with open ends on the side facing away from the side plate 9. The rubber strip 15 is provided with a mounting rod 14 that matches the groove 16. The groove opening of the groove 16 can be provided with an inner folded edge. The structure of the mounting rod 14 matches the groove 16. The rubber strip 15 can not only tightly contact the two sides of the shell, but also effectively protect the shell from wear.
