Description

Technical Field

[0001] The utility model relates to an integrated wire harness detection platform for a high and low temperature chamber, belonging to the field of testing devices. Background Art

[0002] High and low temperature tests belong to one of the environmental reliability tests, which are used to detect the performance of products and are mainly carried out by enterprise R & D personnel during the product R & D stage. When the high and low temperature chamber is conducting high and low temperature tests, terminal AC voltage lines, AC current lines, telemetry lines, CAN lines, DC voltage lines, multi-functional pulse lines, RS45 lines, RS232 lines, network lines, antennae, various power lines, signal lines, and communication lines are all mixed together, and various problems often occur, delaying work and resulting in low test efficiency. For example: there is no identification, it is difficult to distinguish, and there are cases of incorrect connection of the outgoing wires; frosting will occur when a fault occurs in a low temperature environment, affecting data acquisition; the number of terminal tests during the test is limited, which is easy to confuse; there are problems such as mutual interference between lines. Content of the Utility Model

[0003] The purpose of the utility model is to overcome the defects and deficiencies existing in the prior art, and to provide an integrated wire harness detection platform for a high and low temperature chamber.

[0004] An integrated wire harness detection platform for a high and low temperature chamber includes a box body. A test chamber, a heating component for increasing the temperature of the test chamber, and a cooling component for decreasing the temperature of the test chamber are arranged in the box body. A wiring terminal test tooling is arranged in the test chamber. The wiring terminal test tooling includes AC voltage and current wiring terminals and auxiliary wiring terminals arranged in upper and lower rows. The AC voltage and current are placed in the upper row, and the signal lines and communication lines are placed in the lower row. By separating the strong electricity from the weak electricity, various lines are prevented from crossing each other, solving the problem of mutual interference and influence, realizing the separation of strong electricity from weak electricity, and solving the problems of abnormal terminal Ethernet communication and data interruption at high temperatures. This wiring terminal test tooling can read the data in the terminal at any time, and has the function of real-time reading and saving the temperature rise data of the terminal CPU, which can solve the data loss caused by communication anomalies. During the high and low temperature tests of the high and low temperature chamber, it can be reused repeatedly, reducing costs, improving the wiring efficiency, making the wiring firm and reliable, and at the same time solving the safety hazard of the exposure of strong electricity AC voltage and current, thus avoiding the risk of electric shock.

[0005] Further, the AC voltage and current terminal blocks include an AC voltage terminal block and an AC current terminal block. The AC voltage terminal block is respectively marked with Ua, Ub, Uc, and Un terminal blocks, and the AC current terminal block is respectively marked with Ia+, Ia-, Ib+, Ib-, Ic+, and Ic-. Through the provided terminal block marking diagram, it is convenient to connect the AC voltage and current lines, which is very intuitive and clear at a glance. It can completely solve problems such as reverse connection and misconnection of AC voltage and current, resulting in product burnout at the terminal, incorrect AC sampling measurement, voltage reverse phase sequence, and current reverse direction.

[0006] Preferably, the auxiliary terminal block includes a telemetry line, a CAN line, a DC voltage line, a multi-functional pulse line, an RS485 line, an RS232 line, a network cable, and an antenna terminal block with markings. By connecting the lines normally according to the auxiliary terminal block marking diagram, the connection is firm and the communication is stable. It can avoid communication anomalies in an environment of -45 degrees Celsius, which may cause frosting of various lines at the terminal and affect data stability due to low-temperature frosting.

[0007] Further, the AC voltage and current terminal blocks and the auxiliary terminal block are installed in the test room through a mounting plate. On the inner wall of the test room, several positioning blocks are symmetrically arranged at intervals in the height direction. The mounting plate is fixedly connected to one group of positioning blocks through a detachable structure and fixed at the height in the test room. It can be conveniently connected and disassembled through the detachable structure, and it is also convenient to adjust the height of the mounting plate.

[0008] Further, the positioning block is provided with a mounting hole for installing the detachable structure, and the mounting plate is provided with a docking cavity for the detachable structure to extend into. The detachable structure includes a fixed rod, which includes an outer sleeve rod and an inner sleeve rod sleeved inside the outer sleeve rod. On the upper and lower sides of the outer sleeve rod, there are clamping cavities, and clamping blocks extending out of the outer sleeve rod are arranged in the clamping cavities. The outer wall of the clamping block is clamped with the outer wall of the positioning block to form a fixed connection between the mounting plate and the positioning block, making the disassembly of the detachable structure faster and more convenient, improving the installation and disassembly efficiency, saving time, and reducing production and use costs.

[0009] Further, a sliding sleeve is fixedly sleeved on the inner sleeve rod, and a fixed block is arranged at the bottom of the clamping block. The sliding sleeve and the fixed block are connected by a connecting rod. When it is necessary to separate the positioning block and the mounting plate, the inner sleeve rod is moved outwards. The inner sleeve rod drives the clamping block to move downwards through the sliding sleeve, the connecting rod, and the fixed block and retracts into the clamping cavity, and then the positioning block and the mounting plate can be separated. The operation is simple and fast, with convenience and practicality.

[0010] Preferably, an installation block is provided at the bottom of the clamping cavity. Limit blocks are provided at the bottoms of both sides of the clamping block. The limit blocks are clamped with the clamping cavity. A return spring is connected between the installation block and the limit blocks. The return spring can keep the clamping block extending out of the clamping cavity all the time. The clamping block and the positioning block are abutted to fix the position of the mounting plate.

[0011] Further, a first pulling ring is provided at one end of the inner sleeve rod, and a second pulling ring is rotatably provided at one end of the outer sleeve rod. When disassembly is required, operations are performed through the first pulling ring and the second pulling ring.

[0012] The beneficial effects of the present utility model are as follows: By providing an anti-retreat structure, when the cable tie is used, the anti-retreat rod is clamped with the second tooth group and cooperates with the first tooth group to form double-sided clamping and limiting, so that the effect of tying the cable tie to the material is better and tighter. The bottom of the anti-retreat rod can be telescopic. After the cable tie is tied, the bottom of the anti-retreat rod is pressed to the state of being clamped with the second tooth group, and the limiting gear is rotated so that the end face of the anti-retreat rod abuts against the bottom surface of the limiting gear to form a limit, maintaining the state of the anti-retreat rod extending out, improving the stability and practicability of the cable tie in use.
