Description

Technical Field

[0001] This utility model relates to the technical field of signal connection devices, specifically to a dual-cavity 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] Most connectors in existing technologies use single terminals, which can only transmit a limited number of signal types and cannot meet the transmission requirements of multiple signal types, resulting in low space utilization. On the other hand, to meet the needs of different signal types and power, male and female connectors of the same type are often provided with different models. Due to their similar appearance, they are difficult to distinguish, and it is easy to plug male and female connectors of different models into each other during insertion. This not only affects the normal transmission of signals, but also poses safety hazards and damages to the connectors themselves. In addition, to ensure stable insertion, it is often necessary to provide corresponding insertion positioning parts for different terminals. On this basis, in order to achieve stable insertion, it is also necessary to provide corresponding insertion positioning parts for male and female connectors. Therefore, the insertion positioning parts on the outside of the shell are redundant and complex, which increases the difficulty of insertion operation and prolongs the insertion operation time.

[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 dual-cavity straight connector.

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

[0007] A dual-cavity straight connector includes a housing and a main body located inside the housing. The main body is rotatably snapped into the housing. One end of a cable extends from the rear side into the housing and connects to a front terminal located inside the main body. The connector is characterized in that a first main body and a second main body are symmetrically arranged on both sides of the housing. The first and second main bodies transmit different types of signals that do not interfere with each other. A secondary lock is also inserted into the bottom of the housing. The secondary lock penetrates into the housing and is positioned and engaged with the outer edge of the main body.

[0013] As a further preferred embodiment of the present invention, a main body positioning groove is provided on the front side of the middle part of the main body, and a main body abutment part is provided on the rear side of the middle part of the main body.

[0014] As a further preferred embodiment of the present invention, the secondary lock includes a lock body body, a lock body positioning part is provided protruding upward on the front side of the lock body body, the lock body positioning part can extend into the main body positioning groove and be positioned and engaged with it, a lock body abutting part is provided protruding upward on the rear side of the lock body body, the lock body abutting part abuts and engages with the main body abutting part, and a partition plate is fixedly connected between the lock body positioning part and the lock body abutting part.

[0016] As a further preferred embodiment of this utility model, arc-shaped reinforcing ribs are fixedly provided on both sides of the partition plate.

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

[0018] 1) This utility model provides a dual-cavity straight connector.

[0035] [First Embodiment]

[0036] like Figure 1-8 The first embodiment of this utility model shows a dual-cavity straight connector, including a housing 1 and a main body 2 located inside the housing 1. The main body 2 is rotatably snapped into the housing 1. By rotatably snapping the main body 2 into the housing 1, the main body 2 can drive the terminal 4 and the cable 5 to rotate relative to the housing 2. Thus, the position of the cable in the circumferential direction can be adjusted through the rotation process to prevent excessive twisting and knotting of the cable 5. One end of the cable 5 extends into the housing 1 from the rear and connects to the front terminal 4 located inside the main body 2. A shielding ring 3 is sleeved on the outside of the connection position between the main body 2 and the cable 5. The shielding ring 3 is used to shield other signals that may cause interference, thereby further ensuring stable signal transmission.

[0037] The significant improvement of this embodiment compared to the prior art is that: a first main body 21 and a second main body 22 are symmetrically arranged on both sides of the interior of the housing 1. The first main body 21 and the second main body 22 transmit different types of signals without interference. By increasing the internal cavity of the housing, the first main body and the second main body are symmetrically arranged on both sides of the interior of the housing, thereby realizing the parallel connection of multiple wire harnesses to transmit the required signals respectively, and increasing the utilization rate of the internal space of the housing.

[0038] like Figure 1 As shown, the housing 1 in this embodiment includes a handheld part 11, a plug-in part 12 is fixed on the front side of the handheld part 11, and the terminal 4 is located inside the plug-in part 12. The plug-in part 12 enables the connector to be plugged into other connectors. A connecting part 13 is fixed on the rear side of the handheld part 11. The cable 5 extends into the housing 1 through the connecting part 13, and the connecting part 13 enables the connector to be connected to the cable 5.

[0039] To facilitate differentiation, the outer wall of the plug portion 12 is provided with a color matching part. By providing a color matching part on the outer wall of the plug portion 12, users can easily distinguish between 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.

[0040] like Figure 4 As shown, the outer wall of the insertion part 12 of the first main body 21 is provided with a first insertion positioning part 211 and a second insertion positioning part 212 of the first main body with different cross-sectional shapes. In this embodiment, the cross-sectional shape of the first insertion positioning part 211 of the first main body is set to a rectangle, while the cross-sectional shape of the second insertion positioning part 212 of the first main body is set to a near trapezoid. Thus, the insertion process with different connectors can be realized through different cross-sectional shapes. At the same time, different cross-sectional shapes are also conducive to achieving stable positioning in different directional dimensions after the connectors on both sides are inserted.

[0041] The top of the outer wall of the plug portion 12 corresponding to the second main body 22 is provided with the first plug-in positioning portion 221 of the second main body. By using the first plug-in portion 221 of the second main body as both the plug-in positioning portion of the second main body and the plug-in positioning portion when the connector is plugged into other connectors, the redundant and complex arrangement of the plug-in positioning portion on the outer side of the shell is reduced, while the difficulty of plugging operation and the plugging operation time are reduced.

[0042] like Figure 1 As shown, in this embodiment, a secondary lock 6 is also inserted into the bottom of the outer shell 1. The secondary lock 6 penetrates into the interior of the outer shell 1 and is positioned and engaged with the outer edge of the main body 2, thereby achieving the positioning effect of the main body 2 inside the outer shell 1 through the secondary lock 6.

[0043] To achieve the positioning effect of the main body 2 inside the outer shell 1, such as Figure 7-8As shown, a main body positioning groove 23 is provided on the front side of the middle part of the main body 2, and a main body abutment part 24 is provided on the rear side of the middle part of the main body 2. Correspondingly, the secondary lock 6 includes a lock body 61, a lock body positioning part 62 is provided on the front side of the lock body 61, which can extend into the main body positioning groove 23 and be positioned therewith, and a lock body abutment part 63 is provided on the rear side of the lock body 61, which abuts and cooperates with the main body abutment part 24. By the lock body positioning part 62 extending into the main body positioning groove 23 and being positioned therewith, and by the lock body abutment part 63 abutting and cooperating with the main body abutment part 24, the positioning effect of the main body 2 inside the outer shell 1 is achieved by the secondary lock 6.

[0044] A second main body second insertion positioning part 222 is fixedly connected to the front side of the lock body positioning part 62. The second main body second insertion positioning part 222 is set close to the second main body 22. By using the second main body second insertion positioning part 222 as both the insertion positioning part of the second main body and the insertion positioning part when the connector is inserted with other connectors, the redundant and complex arrangement of the insertion positioning parts on the outer side of the shell is reduced, while reducing the difficulty of insertion operation and reducing the insertion operation time. At the same time, the second main body second insertion positioning part 222 is set close to the second main body 22 to reserve sufficient space for the insertion of the first main body 21.

[0045] As a further preferred option, a partition plate 64 is fixedly connected between the lock body positioning part 62 and the lock body abutment part 63. The partition plate 64 effectively separates the two main bodies. At the same time, arc-shaped reinforcing ribs 641 are fixedly provided on both sides of the partition plate 64. The arc-shaped reinforcing ribs 641 increase the connection strength, can make good contact with the two main bodies, and can achieve a certain degree of limiting effect on the two main bodies.

[0046] This embodiment provides a dual-cavity straight connector. By increasing the internal cavity of the housing, a first main body and a second main body are symmetrically arranged on both sides of the housing, thereby enabling parallel connection of multiple wire harnesses to transmit the required signals and increasing the utilization rate of the internal space of the housing. By providing a color matching part on the outer wall of the insertion part, users can easily distinguish between different models of male and female connectors by appearance, ensuring insertion safety and stable signal transmission, and reducing the possibility of mis-insertion. By using the first insertion part of the second main body and the second insertion part of the second main body as both the insertion positioning part of the second main body and the insertion positioning part when the connector is inserted with other connectors, the redundancy and complexity of the insertion positioning part on the outside of the housing are reduced, while reducing the difficulty and time of insertion operation. By setting the main body to be rotatably snapped into the inside of the housing, the main body can drive the terminals and cables to rotate relative to the housing, thereby adjusting the position of the cable in the circumferential direction through the rotation process to prevent excessive twisting and knotting of the cable.

[0047] 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.
