The examples of the embodiments are shown in the drawings, in which the same or similar reference numerals indicate the same or similar elements or elements with the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary only for explaining the present utility model and should not be construed as a limitation of the present utility model.

[0018] All the features disclosed in this specification, or all the steps in the disclosed methods or processes, except for mutually exclusive features and / or steps, can be combined in any manner.

[0019] Any feature disclosed in this specification (including any additional claims, abstract, and drawings) can be replaced by other equivalent or similar-purpose alternative features unless specifically stated otherwise. That is, unless specifically stated, each feature is only an example of a series of equivalent or similar features.

[0020] Such as Figure 1 、 Figure 2 andFigure 3 As shown in the figure, a quick connector for board-end signal lines of the present utility model includes a male connector 1 and a female connector 2. The male connector 1 and the female connector 2 are inserted into each other. Half-rings 9 are installed on both side surfaces of the male connector 1 and the female connector 2. Two half-rings 9 on each side are combined to form a positioning ring. A locking cover 3 that presses and positions the male connector 1 and the female connector 2 is sleeved outside each positioning ring. An adjusting mechanism for driving the movement of the locking cover 3 is installed at the middle of the male connector 1.

[0021] In this embodiment, the adjusting mechanism includes a fixed column 4, a lead screw 5, an adjusting plate 6 and a hand wheel 7. An installation opening is provided on the male connector 1. The fixed column 4 is installed in the installation opening. An installation hole is provided at the center of the fixed column 4. A sealed bearing is installed in the installation hole. The adjusting plates 6 are installed on the outer side surfaces of the locking cover 3. One end of each adjusting plate 6 is provided with a lead screw hole. The lead screw 5 is threadedly connected to the lead screw hole. The middle of the lead screw 5 is installed in the inner ring of the sealed bearing. One end of the lead screw 5 is fixedly connected to the hand wheel 7. A limit block 8 is installed at the other end of the lead screw 5. Among them, the lead screw takes the sealed bearing as the center line, and the thread pitches of the lead screw on both sides of the center line are arranged in opposite directions, so as to synchronously drive the approaching and moving away of the adjusting plates.

[0022] In this embodiment, the half-ring 9 on the female connector 2 is set lower than the half-ring 9 on the male connector 1.

[0023] In this embodiment, the diameter of the positioning ring matches the inner diameter of the inner cavity of the locking cover 3, which increases the stability after the locking cover and the positioning ring are inserted.

[0024] In this embodiment, a retreat space for the outward movement of the adjusting plate 6 is formed between the outer side surface of the adjusting plate 6 and the hand wheel 7 and between the adjusting plate 6 and the limit block 8. After the adjusting plate moves outward, the adjusting plate can finally fit against the inner side surface of the hand wheel. At this time, the locking cover just disengages from the half-ring of the female connector.

[0025] In this embodiment, both the locking cover 3 and the half-ring 9 are made of metal materials, which increases the firmness and can better complete the connection and fixation between the female connector and the male connector.

[0026] During installation, the male connector can be directly inserted into the female connector. After insertion, the half-rings of the two will abut against each other to form a positioning ring. After rotating the hand wheel, the hand wheel can drive the lead screw, and the rotation of the lead screw drives the adjusting plate, so that the adjusting plates approach inward synchronously. The movement of the adjusting plates synchronously drives the locking cover, and the locking cover can synchronously sleeve outside the positioning ring. The open end surface of the locking cover abuts against the outer wall surfaces of the male connector and the female connector, and the connection stability of the two can be increased by pressing inward.

[0027] Among them, since the upper half ring of the connector female head is lower than the height of the upper half ring of the connector male head, after the locking cover moves outward, the locking cover will first detach from the connector female head, but the other part of the locking cover is still in contact with the half ring on the connector male head to ensure the positioning effect of the locking cover, so that the locking cover can only move up and down along the outer ring surface of the half ring.

[0028] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that are not conceived through creative work should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope defined in the claims.
