Detailed Description of the Preferred Embodiment

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0024] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model.

[0025] Embodiment:

[0026] Referring to Figures 1 - 4 , an automotive signal connector includes a male connection housing 1 and a female connection housing 2. The connection ends of the male connection housing 1 and the female connection housing 2 correspond to each other respectively, and this connection end is a contact member. A male contact member is arranged inside the male connection housing 1, and a female contact member is arranged inside the female connection housing 2, and the male contact member and the female contact member are detachably connected.

[0027] The electrical connection is completed by inserting and mating the male and female contact members on the male connection housing 1 and the female connection housing 2. The male contact member is generally a rigid part, and its shape can be cylindrical (round pin), square columnar (square pin) or flat (insert piece). The male contact member is generally made of brass or phosphor bronze. The female contact member, that is, the jack, is a key part of the contact pair. It relies on the elastic structure to elastically deform when inserted with the pin and generates an elastic force to form a tight contact with the male contact member to complete the connection. There are many types of jack structures, such as cylindrical (slotted, necked-down), tuning fork type, cantilever beam type (longitudinally slotted), folding type (longitudinally slotted), box type (square jack) and hyperbolic wire spring jack, etc. Square pins and square jacks are used in this device, and the shape of the contact member can be adjusted according to the use requirements.

[0028] In addition, a blocking block 3 is fixedly connected to the inner wall of the male connection housing 1, and an inclined plate 8 is fixedly connected to the outer wall of the female connection housing 2, so that the inclined plate 8 and the blocking block 3 can be used in cooperation.

[0029] A clamping box 4 is integrally formed at the top of the male connection housing 1, and a rocker 201 is arranged at the top of the female connection housing 2. The rocker 201 is obliquely arranged and has a certain degree of elasticity. A through hole 401 is formed in the clamping box 4, and the rocker 201 is detachably connected inside the clamping box 4 and abuts against the inner wall of the through hole 401.

[0030] Here, when the male connection housing 1 is inserted into the female connection housing 2, the rocker 201 needs to correspond to the clamping box 4. Subsequently, the rocker 201 is inserted into the clamping box 4. At this time, the top of the rocker 201 will be limited and tilted. Then, when the male connection housing 1 is pushed to move, the rocker 201 will be stuck in the through hole 401, and the outer part of the elastic rocker 201 will fit against the inner wall of the through hole 401, thereby improving the connection effect between the male connection housing 1 and the female connection housing 2, reducing the phenomenon of easy loosening and poor contact, and improving the stability of the signal during transmission.

[0031] It should be explained that a limit box 5 is also fixedly installed on the side wall of the male connection housing 1, and an open end is provided on one side of the limit box 5. A sliding groove 501 is opened on the limit box 5, and a locking block 6 is slidably connected to the sliding groove 501. One end of the locking block 6 is fixedly connected to an arc-shaped plate 602, and the other end of the locking block 6 is fixedly connected to a push plate 601.

[0032] On the female connection housing 2, there is also a limit block 7 corresponding to the open end of the limit box 5. One end of the limit block 7 is provided with a tapered guiding block, and an arc-shaped guiding surface 701 is also provided on the limit block 7, and the guiding block is coupled with the arc-shaped guiding surface 701.

[0033] When the limit box 5 on the male connection housing 1 is connected to the limit block 7 on the female connection housing 2, the locking block 6 can be pushed to one side of the limit box 5 so that it is at the end of the sliding groove 501. Subsequently, the limit block 7 is inserted into the limit box 5 until the limit block 7 is completely inserted into the limit box 5. At this time, the push plate 601 on the locking block 6 is pushed, and it is pushed towards the other end of the sliding groove 501. During this process, the arc-shaped plate 602 will first come into contact with the guiding block on the limit block 7. At this time, force needs to be applied. Under the guiding action of the guiding block, the arc-shaped plate 602 can move outside the guiding block, and a gap will be formed between the arc-shaped guiding surface 701 and the inner wall of the limit box 5. The moving arc-shaped plate 602 will be stuck in this gap, which can increase the friction between the arc-shaped guiding surface 701 and the inner wall of the limit box 5, thereby improving the connection stability between the male connection housing 1 and the female connection housing 2, reducing the loosening situation when the male connection housing 1 and the female connection housing 2 are connected, and ensuring the stability of the automotive signal connection.

[0034] The above is only the preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
