Description

Technical Field

[0001] This utility model relates to the technical field of signal connection devices, and specifically to a straight connector. Background Technology

[0002] Signal connection devices generally include male and female connectors. Signal transmission is achieved by connecting the male and female connectors. Existing signal connection devices are widely used in various fields, such as computer communication and vehicle signal communication.

[0003] In the existing technology, in order to meet the needs of different types and power of transmitted signals, male and female connectors of the same type are often provided with different models. Since they are similar in appearance and difficult to distinguish, it is easy to plug male and female connectors of different models into each other during the insertion process. This not only affects the normal transmission of signals, but also poses safety hazards and damages to the connectors themselves.

[0004] Therefore, there is an urgent need to provide a solution to address the defects and shortcomings of the existing technologies. Summary of the Invention

[0005] In order to overcome the defects and shortcomings of the existing technology, this utility model provides a straight connector.

[0006] The specific solution provided by this utility model is as follows:

[0007] A straight connector includes a housing and a main body located inside the housing. One end of a cable extends into the housing from the rear and connects to a terminal located inside the main body. A locking element is also provided on one side of the housing. The main body is characterized in that it simultaneously achieves axial positioning inside the housing through limiting cooperation with the inner wall of the housing and the locking element, while the main body can drive the terminal and cable to rotate inside the housing. A plug-in positioning part is also provided at the front end of the housing, and a plug-in matching part is also provided on the surface of the housing.

[0008] As a further preferred embodiment of the present invention, the housing includes a front housing and a rear housing connected to each other, wherein the front housing is configured with a square cross-section and the rear housing is configured with a circular cross-section.

[0009] As a further preferred embodiment of the present invention, the insertion positioning part is disposed on the inner wall of the front end of the front housing, and the insertion positioning part is configured with a concave-convex tooth structure and is evenly distributed on the inner wall of the front end of the front housing.

[0010] As a further preferred embodiment of the present invention, the plug-in color matching part is coated on the surface of the housing.

[0011] As a further preferred embodiment of the present invention, a locking member mounting groove for mounting a locking member is provided on one side wall of the housing.

[0012] As a further preferred embodiment of the present invention, a shielding ring is also provided on the outer periphery of the connection position between the front end of the cable and the rear end of the terminal.

[0013] As a further preferred embodiment of the present invention, the outer edge of the main body is provided with a first protrusion, a second protrusion and a third protrusion from front to back. A first groove is formed between the first protrusion and the second protrusion to cooperate with the locking member, and a second groove is formed between the second protrusion and the third protrusion to cooperate with the limiting part of the inner wall of the housing.

[0014] As a further preferred embodiment of the present invention, a radial gap is reserved between the locking member and the first groove.

[0015] As a further preferred embodiment of the present invention, a radial gap is reserved between the limiting part and the second groove.

[0016] As a further preferred embodiment of this utility model, the rear end of the main body and the inner wall of the shell are axially abutted through a stepped position.

[0017] Compared with existing technologies, the technical effects that this utility model can achieve include:

[0018] 1) This utility model provides a straight connector. By coating the surface of the housing with matching colors, users can easily distinguish between different models of male and female connectors by appearance, ensuring safe insertion and stable signal transmission, and reducing the possibility of misinsertion and incorrect insertion.

[0019] 2) This utility model provides a straight connector. By providing a plug positioning part at the front end of the housing, it is easy for users to distinguish between different models of male and female connectors from both color and shape perspectives. The distinction is convenient. Even when the color of the plug matching part falls off, it can still be distinguished by the shape and matching relationship of the plug positioning part, making the distinction reliable and stable.

[0020] 3) This utility model provides a straight connector. By setting the main body to be axially limited inside the housing, the main body can drive the terminals and cables to rotate inside the housing. Thus, the position of the cable in the circumferential direction can be adjusted by rotating the main body and cables inside the housing, so as to prevent the cable from being excessively twisted and knotted.

[0027] [First Embodiment]

[0028] like Figure 1-3 The first embodiment of the present invention provides a straight connector, including a housing 1 and a main body 4 located inside the housing 1. One end of a cable 2 extends into the housing 1 from the rear and is connected to a terminal 3 located inside the main body 4. A shielding ring 5 is also provided on the outer periphery of the connection position between the front end of the cable 2 and the rear end of the terminal, so as to achieve the connection effect while shielding the unexpected signal. A locking member is also provided on one side of the housing 1. The main body 4 can be axially limited inside the housing 1 by simultaneously engaging with the inner wall of the housing 1 and the locking member.

[0029] like Figure 1As shown, the housing 1 in this embodiment includes a front housing 11 and a rear housing 12 connected to each other. The front housing 11 is configured with a square cross-section to facilitate the insertion and positioning between the male connector and the female connector. The rear housing 12 is configured with a circular cross-section to match the outer edge shape of the cable 2 passing through it.

[0030] A locking member mounting groove 13 is provided on one side wall of the housing 1 for installing a locking member. The locking member is installed inside the locking member mounting groove 13 to achieve the axial positioning effect of the main body 4 inside the housing 1.

[0031] The improvement of this embodiment compared to the prior art is as follows:

[0032] In this embodiment, the main body 4 can drive the terminal 3 and cable 2 to rotate inside the housing. This allows the cable's position in the circumferential direction to be adjusted by rotating the main body and cable inside the housing, preventing excessive twisting and knotting of the cable, thereby ensuring stable signal transmission and extending the connector's service life.

[0033] Meanwhile, the front end of the housing 1 is provided with a plug positioning part 111, and the surface of the housing 1 is also provided with a plug color matching part 112. By coating the surface of the housing 1 with the plug color matching part 112, users can easily distinguish different models of male and female connectors by appearance, ensuring plugging safety and stable signal transmission, and reducing the possibility of mis-plugging and incorrect plugging. By providing a plug positioning part at the front end of the housing, users can distinguish different models of male and female connectors by both color and shape, making differentiation convenient. Even when the color of the plug color matching part falls off, differentiation can still be achieved by the shape and matching relationship of the plug positioning part, making differentiation reliable and stable.

[0034] like Figure 1 As shown, in this embodiment, the insertion positioning part 111 is disposed on the inner wall of the front end of the front housing 11. The insertion positioning part 111 is configured with a concave and convex tooth structure and is evenly disposed on the inner wall of the front end of the front housing 11. Thus, the mutual insertion of male connectors and female connectors of the same model can be realized through the corresponding and adapted insertion positioning part 111, ensuring insertion safety and stable signal transmission, and reducing the possibility of misinsertion and incorrect insertion.

[0035] In this embodiment, the mating color part 112 is coated on the surface of the housing 1. As a further preferred embodiment, the mating color part 112 can use different colors to mark different models of connectors, so that male and female connectors with mating color parts 112 of the same color can be mated. For example, only male and female connectors with mating color parts 112 of yellow can be mated together. Alternatively, different color combinations can be used to mark different models of connectors, so that male and female connectors with mating color parts 112 of the same color combination can be mated together. For example, only male and female connectors with mating color parts 112 of red, yellow and blue in sequence can be mated together.

[0036] By coating the surface of the housing with matching colors, users can easily distinguish between different models of male and female connectors by appearance, ensuring safe insertion and stable signal transmission, and reducing the possibility of misinsertion and incorrect insertion.

[0037] like Figure 3 As shown, the outer edge of the main body 4 is provided with a first protrusion 41, a second protrusion 42 and a third protrusion 43 from front to back. A first groove 44 is formed between the first protrusion 41 and the second protrusion 42 to cooperate with the locking member. A second groove 45 is formed between the second protrusion 42 and the third protrusion 43 to cooperate with the limiting part 14 of the inner wall of the housing 1. Thus, in the axial direction, the main body 4 can achieve the axial limiting effect inside the housing 1 by simultaneously cooperating with the limiting part 14 of the inner wall of the housing 1 and the locking member.

[0038] Furthermore, preferably, a radial gap is reserved between the locking member and the first groove 44, and a radial gap is reserved between the limiting part and the second groove 45. The reserved radial gaps facilitate the rotation of the main body 4, terminal 3, and cable 2 within the housing, thereby minimizing the obstruction caused by unintended contact with the limiting part 14 and locking member on the inner wall of the housing. Because there is axial friction between the locking member and the first groove 44, and between the limiting part and the second groove 45, the main body 4, while able to rotate the terminal 3 and cable 2 within the housing, can also remain at the target position after rotation due to this axial friction. Figure 3 As shown, the rear end of the main body 4 and the inner wall of the housing 1 can be axially abutted through a stepped position, so as to confirm whether the main body 4 is axially installed in place when it is installed into the housing 1 from the rear.

[0039] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
