Description

Technical Field

[0001] This utility model belongs to the technical field of terminal testing, specifically relating to a testing simulation fixture. Background Technology

[0002] Terminals have applications in many fields, such as in automotive electronic systems, where they are mainly used to connect various electronic components and sensors to ensure stable signal and power transmission; they can also be used in integrated circuit chips as pins.

[0003] During the terminal manufacturing process, semi-finished and finished products must be periodically inspected to ensure their quality meets requirements. Terminal inspection standards cover multiple aspects, including materials, appearance, dimensions, and performance. Due to the small size and high precision of terminals, dimensional inspection requires fixing one terminal on a 2D image measuring instrument to measure its size and shape, and then exporting the measured dimensions for verification. However, this inspection process is time-consuming, and it is crucial to ensure that the placement position is consistent each time to guarantee the accuracy of the measurement results. To achieve efficient and accurate terminal quality inspection, a testing simulation fixture has been developed. Summary of the Invention

[0004] This invention provides a testing simulation fixture that accurately mimics the actual installation state of terminals, enabling the detection of key terminal dimensions and further accelerating terminal testing efficiency.

[0005] The technical solution adopted in this utility model is as follows: A testing simulation fixture includes a base, a first testing seat, and a second testing seat. The first testing seat protrudes from the top surface of the base and has several first testing slots vertically extending through its top and sides. The second testing seat is located to the upper right of the first testing seat and is embedded in the base. The second testing seat has a first plane flush with the top surface of the base and a second plane recessed inward relative to the top surface of the base. The second plane is far from the first testing seat, and several second testing slots are vertically spaced along its length on the second plane, with the second testing slots extending vertically through the base.

[0006] Preferably, the first detection channel includes at least a front detection channel formed on the front side of the first detection seat, a right detection channel formed on the right side of the first detection seat, and a rear detection channel one and a rear detection channel two formed at intervals on the rear side of the first detection seat; a plurality of second detection channels correspond one-to-one with the front detection channel, the right detection channel, the rear detection channel one, and the rear detection channel two from right to left.

[0007] Preferably, the base is also provided with two third detection seats protruding from the top surface of the base. The top of the third detection seat is provided with several third detection slots spaced apart along its width direction. The third detection slots are arranged through the left and right sides, and the bottom surface is flush with the top surface of the base. One third detection seat is located to the right of the first detection seat and below the second detection seat, and the other detection seat is located to the upper right of the first detection seat and to the left of the second detection seat.

[0008] Preferably, the base has a through groove, and the first detection seat, the second detection seat, and the third detection seat are all disposed in the through groove of the base and do not come out; the first detection groove located on the side of the first detection seat penetrates downward through the bottom surface of the first detection seat.

[0009] Preferably, the second detection seat consists of a first fixed block and a second fixed block disposed on the rear side of the first fixed block. The top rear side of the first fixed block has an L-shaped clearance area that extends through its left and right sides. The top front side of the first fixed block is a first plane, and the horizontal plane of its L-shaped clearance area and the top surface of the second fixed block together form a second plane. The second detection through slot is formed by the openings of the opposite sides of the first fixed block and the second fixed block.

[0010] Preferably, the top of the second detection channel is a square through hole that is larger at the top and smaller at the bottom. The square through hole is formed by the common opening of the top of the opposite sides of the fixing block 1 and the fixing block 2. The second detection channel located at the lower end of the square through hole is opened on the front side of the fixing block 2. The opposite side of the fixing block 1 is the front inner wall of the second detection channel.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: This testing simulation fixture is a relatively simple but intuitive tooling designed based on the installation environment of a complete set of products. It can quickly detect the main dimensions of the terminals (such as width, length, and straightness) and the position and bending degree of the upper and lower vertical parts, and determine whether they are qualified or not, thereby further accelerating the terminal testing efficiency.

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the following description, in conjunction with specific embodiments, further illustrates this utility model. The accompanying drawings are for illustrative purposes only, representing schematic diagrams rather than actual physical objects, and should not be construed as limiting this patent. It is understandable that some well-known structures and their descriptions may be omitted in the drawings for those skilled in the art. For ease of understanding, the terms "up," "down," "front," "back," "left," and "right" described in this application are based on... Figure 1 and Figure 2 In other words, it is not specifically limited.

[0017] like Figure 3 The complete product assembly shown includes four different specifications of terminals 100, each consisting of an upper vertical section 101, a horizontal connecting section 102, and a lower vertical section 103. The height of the upper vertical section 101 corresponding to each terminal is equal, as are the heights of their lower vertical sections 103. The horizontal connecting section 102 is located between the upper vertical section 101 and the lower vertical section 103, and varies between the two sections, but can be understood as consisting of one or two consecutive L-shaped bends. This testing simulation fixture primarily simulates the installation environment of a complete product assembly, rapidly detecting the main dimensions of the terminals (e.g., width, length, flatness, bending degree) and the position and bending degree of the upper and lower vertical sections to determine their compliance. During terminal testing, the entire product assembly is installed in this fixture. If all components are properly installed, it can be understood that the main dimensions of the terminals and the position and bending degree of the upper and lower vertical sections meet the requirements, and these aspects do not require further two-dimensional measurement. The height of the upper and lower vertical sections of the terminals is detected in conjunction with other workpieces.

[0018] This utility model's testing simulation fixture is a relatively simple yet intuitive tooling specifically designed based on the usage scenarios of terminals. It precisely mimics the actual installation state of the product, ensuring that its dimensions meet requirements, thereby achieving efficient and accurate terminal quality testing. Its application can accelerate terminal testing efficiency. Simultaneously, it can serve as a stable, reliable, and highly repeatable reference or support platform to fix terminals for other tests, ensuring consistent placement each time and guaranteeing the accuracy of measurement results.

[0019] Specifically, the tool comprises a base 1, a first detection seat 2 and a second detection seat 3. The first detection seat 2 protrudes from the top surface of the base 1, and a plurality of first detection through grooves penetrating through the top and the side of the first detection seat are vertically formed in the side of the first detection seat; the second detection seat 3 is located at the upper right of the first detection seat 2 and is embedded in the base, the second detection seat 3 has a first plane 5 flush with the top surface of the base and a second plane 6 recessed inward relative to the top surface of the base, the second plane 6 is away from the first detection seat 2, a plurality of second detection through grooves 7 are vertically formed on the second plane 6 at intervals along the length direction of the second plane, and the second detection through grooves 7 penetrate vertically up and down.

[0020] In this embodiment, there are 4 first detection through grooves and 4 second detection through grooves. The first detection through grooves comprise a front detection through groove 8 formed in the front side surface of the first detection seat, a right detection through groove 9 formed in the right side surface of the first detection seat, a first rear detection through groove 10 and a second rear detection through groove 11 formed in the rear side surface of the first detection seat at intervals; the 4 second detection through grooves 7 sequentially correspond to the front detection through groove 8, the right detection through groove 9, the first rear detection through groove 10 and the second rear detection through groove 11 one by one from right to left, and respectively correspond to a whole group of 4 products with different specifications.

[0021] Wherein, the arrangement of the first detection seat and the second detection seat simulates the position of a product during installation, and accurately reproduces the key installation interface of the product in the use scenario. The groove depth and width of the first detection through grooves and the second detection through grooves are strictly manufactured according to the height and width dimensions of the product. The clamp judges whether the width, length, flatness, position of upper and lower vertical parts and bending degree of a terminal meet the installation requirements by verifying whether the dimensions and position tolerance of the 4 detection through grooves on the first detection seat and the second detection seat are qualified. If all the requirements are met, the detection is considered qualified, and two-dimensional measurement is not required.

[0022] Further, both the first detection through grooves and the second detection through grooves are rectangular through grooves, and the vertical side walls of the through grooves have high vertical precision, which can be understood as absolutely perpendicular around. When a terminal is put in, the upper vertical part and the lower vertical part of the terminal respectively correspond to corresponding detection through grooves, and are gradually pressed into the first and second detection through grooves; the outer side wall of the terminal can contact with the vertical inner wall of the clamp, and primary rough positioning is carried out in X and Y directions (horizontal directions), which plays the role of primary positioning and reference; this ensures that the center position of the workpiece is basically consistent every time the workpiece is put in, and lays a foundation for subsequent more accurate positioning and other detection.

[0023] Furthermore, the base 1 is also provided with two third detection seats 4 protruding from the top of the base. Two third detection slots 12 are spaced apart along the width of the top of each third detection seat 4, extending through the base horizontally, with their bottom surfaces flush with the top surface of the base. One third detection seat 4 is located to the right of the first detection seat 2 and below the second detection seat 3, while the other detection seat 4 is located to the upper right of the first detection seat 2 and to the left of the second detection seat 3. The third detection slots correspond to the horizontal connection portion of the terminal and are used to detect whether the horizontal connection portion is twisted. If the terminal is twisted in the middle, the terminal cannot be placed into the first or second detection slots.

[0024] Considering that the workpiece may be repeatedly pushed in, pulled out, or slid onto the fixture during the inspection process, and to ensure positioning accuracy, the base, first inspection seat, second inspection seat, and third inspection seat must withstand frequent, frictional operations. Therefore, all three components are made of high-hardness, high-wear-resistant materials. Additionally, the base has multiple vertical planes on its side, facilitating vertical placement or fixation at multiple angles, which is beneficial for terminal inspection.

[0025] Correspondingly, to save costs, a through slot 13 is provided on the base 1. The first detection seat 2, the second detection seat 3, and the third detection seat 4 are all set in the through slot 13 and do not come out. The first detection slot located on the side of the first detection seat 2 penetrates downward through the bottom surface of the first detection seat 2. The first detection seat, the second detection seat, and the third detection seat can be secured by interference fit or bolts to ensure that they do not come out, and there is no specific limitation.

[0026] More specifically, in order to facilitate the processing of the second detection slot, the second detection seat 3 is composed of a first fixing block 31 and a second fixing block 32 located on the rear side of the first fixing block. The top rear side of the first fixing block 31 is provided with an L-shaped clearance area 14 that runs through its left and right sides. The top front side of the first fixing block 31 is the first plane 5, and the horizontal plane of its L-shaped clearance area 14 and the top surface of the second fixing block 32 together form the second plane 6. The second detection slot 7 is formed by the openings of the opposite sides of the first fixing block 31 and the second fixing block 32.

[0027] The top of the second detection channel 7 is a square through-hole 71, which is wider at the top and narrower at the bottom. The square through-hole 71 is formed by the common openings on the top of the opposite sides of the fixing block 31 and the fixing block 32. The second detection channels 7 located at the lower end of the square through-hole 71 are all opened on the front side of the fixing block 32. The opposite side of the fixing block 31 is the front inner wall of the second detection channel 7. The square through-hole can guide the vertical part of the terminal to enter.
