[0001] This utility model relates to the field of connector technology, and in particular to a highly reliable automotive connector. Background Technology

[0002] Automotive connectors have high reliability requirements, mainly reflected in the following aspects:

[0003] 1. Insertion and extraction force: It is necessary to ensure appropriate insertion and extraction force. It should not be too large, which may cause difficulty in insertion and extraction, damage the interface or affect the convenience of use, nor should it be too small, which may cause poor contact and easy loosening and detachment.

[0004] II. Vibration and shock resistance: It can maintain a stable connection under vibration and shock during vehicle operation, without interruption, loosening or damage, so as to ensure the continuity of the electrical system;

[0005] 3. Mechanical life: It needs to have sufficient number of insertion and removal cycles and service life, usually requiring a lifespan of several thousand or even tens of thousands of insertion and removal cycles.

[0006] Existing automotive connectors are poorly designed, with inadequate contact point structure, resulting in uneven or insufficient contact pressure. Vibrations and impacts during vehicle operation can easily cause the contact points to loosen or shift, increasing contact resistance and affecting signal transmission and power supply.

[0028] Please see Figure 1-3 This application provides a highly reliable automotive connector, comprising: a first wiring portion 1, a second wiring portion 2, a connecting portion 3, and a plastic housing 4. One end of the connecting portion 3 is fixedly connected to the first wiring portion 1, and the other end is fixedly connected to the second wiring portion 2. In use, the first wiring portion 1, the second wiring portion 2, and the connecting portion 3 are housed within the plastic housing 4, and the first wiring portion 1 is used for mating with other male connector terminals.

[0029] Furthermore, the first wiring portion 1 includes a hollow frame 11 and a clamping portion 12 disposed within the hollow frame 11. The clamping portion 12 is used to guide and fix the male connector terminal. A limiting portion 13 is provided on the outer side of the clamping portion 12. The limiting portion 13 is used to limit the excessive outward expansion of the clamping portion 12 when the male connector terminal is inserted, to prevent the material of the clamping portion 12 from yielding or deforming, thereby ensuring that the terminal makes elastic contact. Specifically, the limiting portion 13 is a sheet-like structure integrally formed with the clamping portion 12 and inclined outward from the clamping portion 12. When the connector is inserted with the male connector, the sheet-like structure abuts against the inner wall of the plastic housing 4, thereby limiting the excessive outward expansion of the clamping portion 12.

[0030] In this embodiment, the clamping part 12 consists of two opposing first spring pieces, and the limiting part 13 is located outside the first spring pieces.

[0031] Furthermore, the distance between the two first springs extending inward from the male insertion end gradually decreases, and the limiting part 13 is formed by the end of the first spring extending outward, which is used to limit the yielding and deformation of the spring caused by excessive outward expansion of the first spring when the connector is inserted with the male socket, thereby ensuring that the terminal is in elastic contact.

[0032] Preferably, the limiting portion 13 is perpendicular to the direction of insertion of the terminal or wire. This arrangement can better restrict the position of the first spring contact.

[0033] Furthermore, the first wiring portion 1 also includes a first fixing portion 14, which is used to fix the terminal to the plastic housing 4. When the terminal composed of the first wiring portion 1, the second wiring portion 2, and the connecting portion 3 is inserted into the plastic housing 4, the first fixing portion 14 is embedded in the inner wall of the plastic housing 4. In this embodiment, the first fixing portion 14 is a second spring extending outward from the hollow frame 11, and the second spring is located at the end of the first spring away from the insertion port. When the terminal composed of the first wiring portion 1, the second wiring portion 2, and the connecting portion 3 is inserted into the plastic housing 4, the end of the second spring is embedded in the inner wall of the plastic housing 4. Furthermore, the plastic housing 4 is provided with a receiving groove, and the end of the second spring is embedded in the receiving groove. Preferably, there are two second springs, and the two second springs are respectively located on two opposite sides of the hollow frame 11, so that the connector is more firmly fixed to the plastic housing 4, avoiding shaking and making the electrical connection more stable.

[0034] Furthermore, the connecting portion 3 is integrally formed with the first wiring portion 1 and the second wiring portion 2. This design makes the connector more durable and reduces production costs. Preferably, the connecting portion 3 has a semi-circular cross-section, which facilitates wire bonding.

[0035] Furthermore, the second wiring portion 2 includes a support portion 21 and a fixing portion 22. The support portion 21 is used to accommodate terminals or wires, and the fixing portion 22 is used to fix the terminals or wires placed on the support portion 21 to the second wiring portion 2. In this embodiment, the support portion 21 is a groove-shaped structure with a semi-circular cross-section extending from the connecting portion 3, and the second fixing portion 22 is a second extension extending from the edge of the support portion 21 and rotatable along the edge of the support portion 21.

[0036] Preferably, the second extension is symmetrically arranged on both sides of the second wiring portion 2. More preferably, each side edge of the second extension is provided with a plurality of second extensions at intervals to better secure the connected terminal or wire. Even more preferably, the second extension located at the outermost end of the second wiring portion 2 is the longest, which facilitates the insertion of the terminal or wire to be connected.

[0037] Compared with the prior art, the beneficial effects of the embodiments of this application are as follows:

[0038] By providing a limiting part 13 on the outer side of the clamping part 12, the clamping part 12 is effectively prevented from being excessively stretched outward, thereby preventing the clamping part 12 from yielding or deforming, thus ensuring that the terminal is in elastic contact; by providing a first fixing part 14 on the first wiring part 1, the connection between the connector and the outer plastic shell 4 is made more stable.

[0039] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and this utility model also intends to include these modifications and variations.
