Detailed Description

The following detailed description of the preferred embodiments of the present application, taken in conjunction with the accompanying drawings, will make the advantages and features of the present application more readily appreciated by those skilled in the art, and thus will more clearly define the scope of the invention.

Referring to fig. 1, a structure of a positioning plate for a radiation interference test of carrier equipment according to an embodiment of the present disclosure is shown.

As shown in fig. 1, the positioning plate for testing radiation interference of carrier equipment includes a plate body 10, a carrier equipment fixing portion 1 and a wiring groove 2.

The plate body 10 is made of a non-conductive material having a dielectric constant of less than 1.4 and may have a height of 5 cm to meet the test requirements.

The carrier equipment fixing part 1 is used for fixing carrier equipment and comprises a carrier equipment clamping groove matched with the appearance of the carrier equipment. The carrier equipment clamping groove can limit and fix the carrier equipment so as to prevent the carrier equipment from moving in the test process.

The wiring groove 2 is arranged on one side of the carrier equipment fixing part 1 and used for wiring and fixing signal wires of the carrier equipment, and comprises a plurality of clamping structures 3 which are arranged on one side or two sides of the wiring groove 2 and used for fixing the signal wires. Specifically, the length of the wiring groove 2 can be matched with the length of the signal wire of the carrier device, so that the wiring groove 2 has enough length to accommodate the signal wire. In an embodiment, the distance from the wiring groove to the nearest edge of the board body 1 may be 10 cm, so that the signal line can be quickly positioned to a position meeting the test requirement, and of course, distances of other values may be set according to the actual test requirement.

In one embodiment, the cabling trough 2 includes a first cabling trough 21 and a second cabling trough 22. Specifically, one end of the first wiring groove 21 is communicated with the carrier device fixing part 1, and the other end is communicated with the second wiring groove 22; and one end of the second wiring groove 22 is communicated with the second wiring groove 22, and the other end of the second wiring groove 22 is provided with a holding groove 5 for holding a connection port of a signal wire. Wherein, the joint of the first wiring groove 21 and the second wiring groove 22 is bent. Through dividing into two parts of buckling relatively with trough 2 for the signal line of overlength can buckle and place, with the space that the reduction was walked the line and is taken, and then reduces the area size that the locating plate was occupied.

The accommodating groove 5 is used for accommodating the terminal connecting ends of the signal wires so as to accommodate all the signal wires into the wiring groove 2. Further, the accommodating groove 5 is provided with a length mark for marking the length of the signal line on at least one side

The slotting position of the accommodating groove 5 is related to the length of the signal wire, and the relative lengths and positions of the cabling groove 2 and the accommodating groove 5 can be adjusted according to the actual condition of the signal wire.

The clamping structure 3 can be arranged at the notch position of the wiring groove 2 and is used for fixing the signal wire in the wiring groove 2. In one embodiment, the clamping structure 3 may be an elastic member to facilitate a user to clamp a signal wire into the cabling channel 2 or remove it from the cabling channel 2. Further, chucking structure 3 extends from notch department one side or both sides of trough 2 to there is the interval with the opposite side is alternate, and the user can pass through the interval location with the wire rod, and utilizes chucking mechanism deformation in order to impress this signal line to trough 2 or take out the signal line.

In order to avoid the influence of the placement of the signal wire on the radiation interference test process of the carrier equipment, a separation part 4 is formed between the carrier equipment fixing part 1 and the wiring groove 2, and the signal wire is isolated from the carrier equipment through the separation part 4. The separating part 4 is provided with a curved end 41 for signal wires to be bent at the joint of the carrier device fixing part 1 and the wiring groove 2, and the bending loss of the signal wires at the bending part between the wiring groove 2 and the carrier device can be reduced through the curved end 41.

In summary, the carrier device fixing portion 1 and the wiring groove 2 are matched to fix and place the carrier device and the signal line thereof, so that the carrier device displacement and the interference of the signal line thereof to the test items can be avoided, and the reliability of the carrier device test process is improved.

Referring to fig. 2, another structure of a positioning plate for a radiation interference test of carrier equipment according to an embodiment of the present disclosure is shown.

As shown in fig. 2, in an embodiment, the positioning plate for testing radiation interference of carrier equipment is provided with a plurality of accommodating grooves 5 for accommodating connection ports of signal lines in a wiring groove 2, and the accommodating grooves 5 are arranged at intervals along a wiring direction of the wiring groove 2, as compared with fig. 1. Because the carrier equipment is influenced by different designs of the applied vehicles, the carrier equipment can have signal wires with different lengths, and at the moment, the positioning plate can be compatible with carrier equipment with different design specifications at the same time by arranging the accommodating grooves 5 at different positions in the wiring groove 2.

In one embodiment, at least one clamping structure 3 is disposed between each receiving groove 5 and the carrier device fixing portion 1, so as to fix the wires between the carrier device fixing portion 1 and the receiving groove 5 better. In addition, at least one side of each holding tank 5 is provided with a length mark for marking the length of the signal wire, so that each holding tank 5 has a corresponding length standard of the signal wire, and a user can conveniently and quickly determine whether the positioning plate is suitable for the current specification of the carrier equipment based on different lengths of the signal wire.

In addition, a wire accommodating area 6 for accommodating an unnecessary signal wire is provided at the end of the wiring groove 2 on the other side with respect to the carrier device. When the signal wires still have more wires growing relative to the wiring slots 2, the wires growing out can be accommodated in the wire accommodating area 6, so as to avoid the situation that the signal wires are placed in the positioning plate everywhere, thereby affecting the radiation interference test of the carrier equipment.

In summary, the positioning plate for the carrier device radiation interference test in fig. 2 can better adapt to more use conditions in the radiation interference test by improving the number of the holding grooves, the wire holding area and the like, and thus can improve the practicability of the positioning plate.

The embodiments of the present application have been described in detail with reference to the drawings, but the present application is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present application within the knowledge of those skilled in the art.
