Description

Technical Field

[0001] The utility model relates to an ultra-short self-pressing optical and electrical field connector and an optical and electrical hybrid cable. Background Art

[0002] For existing optical and electrical communication devices such as transmitting antennas, communication base stations, 5G small base stations, a large number of indoor optical and electrical devices, etc., two types of connectors are required for their optical signal connection and power connection respectively. Most of them also require two different cable connections to separately achieve their respective functions. Although optical and electrical hybrid cables have begun to be applied at present, optical and electrical connectors are still separate and independent, and most of them can only be pre-fabricated in the factory and cannot be connected on-site as needed. This connection method is inconvenient, difficult to connect and has many problems in actual applications.

[0003] Publication No. CN202110294237.5 discloses a field-assembled optical and electrical hybrid connector, which includes a connector body. A conductive module that can be quickly assembled is arranged in the connector body. A conductive contact point that can be quickly and movably connected is arranged at the front end of the conductive module, and the rear end of the conductive module can be connected to an external wire on-site. In this technical solution, the conductive wire needs to be inserted into the conductive module and then connected to the conductive contact point. On the one hand, it involves the assembly of multiple components and has a complex structure. On the other hand, the conductive contact point is only arranged in the hollow groove and has no special structural design, making it difficult to ensure the stable and reliable connection between the conductive wire and the contact point. Therefore, the difficulty of on-site assembly is increased. Summary of the Utility Model

[0004] Aiming at the problems existing in the prior art, the utility model provides an ultra-short self-pressing optical and electrical field connector and an optical and electrical hybrid cable, which have a simple structure, can quickly and accurately complete the docking of the optical and electrical hybrid cable inserted into the connector, improve the installation efficiency, and meet the use requirements in different scenarios.

[0005] The utility model adopts the following technical solutions: An ultra-short self-pressing optical and electrical field connector includes a connector body and an end sleeve. An optical fiber docking assembly is arranged in the connector body. An optical and electrical hybrid cable insertion groove is formed at the rear of the connector body. It is characterized in that a conductive contact piece is also configured on the connector body. A piercing part capable of piercing the hybrid cable is formed at the rear end of the conductive contact piece. A gland is arranged at the rear of the connector body, and two downward pressing bumps are formed in the gland.

[0006] Preferably, at least two end faces of the conductive contact piece are exposed outside the end sleeve at the front end.

[0007] Preferably, the two end faces exposed outside the end sleeve are located on the side face and the bottom face respectively.

[0008] Preferably, the gland is a flip-type gland. The front end of the gland is connected to the connector body through a rotating shaft. Grooves are formed on both sides of the rear part of the gland, and guiding and limiting blocks matching the grooves are formed on both sides of the rear part of the connector body.

[0009] Preferably, an optical fiber docking switch is formed on the upper part of the optical fiber docking assembly, and the optical fiber docking switch is exposed outside the end sleeve.

[0010] Preferably, clamping blocks are formed on both sides of the optical fiber docking switch, and bayonet sockets matching the clamping blocks are formed on the upper part of the end sleeve body.

[0011] Preferably, an integrally convex blocking block is formed on the rear part of the end sleeve.

[0012] Preferably, an integrally protective cover is arranged at the front part of the end sleeve, and the protective cover covers and blocks the conductive contact pieces and part of the optical fiber docking switch.

[0013] Preferably, a guiding groove for the optical fiber to penetrate is formed at the center of the connector body.

[0014] The present utility model also discloses a field-type optical and electrical hybrid cable which is integrally inserted into the insertion groove of the above-mentioned connector. It is characterized in that it includes an optical fiber at the center and conductive wires arranged at intervals on both sides of the optical fiber. An outer cable is covered outside the optical fiber and the conductive wires, and two puncture guiding grooves are respectively formed at the top and bottom of the outer cable where the conductive wires are located.

[0015] The beneficial effects of the present utility model are as follows:

[0016] 1. A conductive contact piece puncture part capable of puncturing the optical and electrical hybrid cable is formed at the rear part of the connector body. After the hybrid cable is inserted, it can be quickly and stably docked with the conductive contact piece in cooperation with the gland.

[0017] 2. Two groups of conductive contact pieces form four exposed end faces on the end sleeve, which is convenient for external connection and conduction. And through these two groups of contact pieces, it is possible to adapt to the two national standard specifications requirements without separately setting two specifications of products.

[0018] 3. A brand-new optical and electrical hybrid cable is designed, and four puncture guiding grooves for the conductive contact pieces are opened on the outer cable. This not only reduces the wall thickness of this part of the outer cable, but also can reduce the locking pressure, promote the stable connection of the power supply, enhance the strength of the optical and electrical hybrid cable, and the overall concave-convex structure of the outer cable can strengthen the overall strength of the cable.

[0019] 4. An integrally protective cover is arranged, which can not only protect the end face of the optical fiber, but also prevent personnel from electric shock and protect the optical fiber switch from accidental opening. Description of the Drawings

Specific embodiments

[0027] The following further elaborates the present utility model in conjunction with specific embodiments.

[0028] As Figures 1 - 5 shown, a super-short self-pressing optical and electrical on-site connector includes a connector body 6 and an end sleeve 3. An optical fiber docking assembly 24 is arranged inside the connector body 6. An optical and electrical hybrid cable insertion groove 24 is formed at the rear of the connector body. A conductive contact piece 13 is also configured on the connector body. A piercing part 23 capable of piercing the hybrid cable is formed at the rear end of the conductive contact piece. A gland 5 is arranged at the rear of the main body of the connector 6. Two downward pressing convex blocks 26 are formed inside the gland. The optical and electrical hybrid cable 8 is inserted into the connector body from the rear. Engaging teeth 18 are formed at the rear inside the connector body to clamp the outer cable. Since the piercing part is formed at the rear end of the conductive contact piece, it can directly pierce the conductive wires on both sides of the hybrid cable, thereby realizing circuit conduction. And the downward pressing convex blocks formed inside the gland can assist in downward pressing to pierce the outer cable. The optical fiber part is connected through the optical fiber docking assembly inside the connector body. Therefore, the optical and electrical hybrid cable can be quickly and accurately inserted into the connector for docking, improving the installation efficiency and meeting the usage requirements in different scenarios.

[0029] In one embodiment, at least two end faces of the conductive contact piece 13 are exposed outside the end sleeve 3 at the front end.

[0030] Specifically, the two end faces exposed outside the end sleeve 3 are respectively located on the side surface 21 and the bottom surface 22. The conductive contact pieces form two exposed end faces on the end sleeve, which is convenient for external connection and conduction. And through these two groups of contact pieces, there is no need to separately set two specifications of products to meet the requirements of the two national standard specifications.

[0031] In one embodiment, the gland 5 is a flip-type gland. The front end of the gland is connected to the connector body 6 through a rotating shaft 15. Grooves 7 are formed on both sides of the rear part of the gland 5, and guiding and limiting blocks 17 matching the grooves 7 are formed on both sides of the rear part of the connector body 6. This structure ensures reliable fixation of the gland to the optical and electrical hybrid cable.

[0032] In one embodiment, a hook 19 is formed at the lower part of the rear end of the gland 5, and a clamping groove 20 matching the hook is formed at the lower part of the rear end of the connector body. This structure ensures stable cooperation between the gland and the connector body.

[0033] In one embodiment, an optical fiber docking switch 2 is formed at the upper part of the optical fiber docking assembly 25, and the optical fiber docking switch 2 is exposed outside the end sleeve 3. The optical fiber docking inside the optical fiber docking assembly is mainly controlled by the external optical fiber docking switch.

[0034] Specifically, the optical fiber docking switch 2 forms retaining pieces 12 on both sides, and clamping blocks 11 are formed at the lower part inside the retaining pieces 12. A bayonet 14 matching the clamping blocks 11 is formed at the upper part of the connector body 6. The switch is positioned through this structure.

[0035] In order to facilitate the insertion and extraction of the end sleeve, an integrally outwardly convex blocking block 4 is formed at the rear part of the end sleeve.

[0036] In order to protect the optical fiber end face, prevent electric shock to personnel and prevent the switch from being accidentally turned on, an integral protective cover 1 is arranged at the front part of the end sleeve 3, and the integral protective cover covers and blocks the conductive contact piece 13 and part of the optical fiber docking switch 2.

[0037] In order to facilitate the accurate docking and penetration of the optical fiber into the connector body, a guiding groove 16 for the optical fiber to penetrate is formed at the center of the connector body 6.

[0038] As Figure 6 shown, an optical and electrical hybrid cable is integrally inserted into the insertion groove 24 of the above connector.

[0039] It includes an optical fiber 9 at the center and conductive wires 10 arranged at intervals on both sides of the optical fiber. The outside of the optical fiber and the conductive wires is covered with an outer cable. Piercing guiding grooves 27 are respectively formed at the top and bottom of the outer cable where the conductive wires are located. Piercing guide grooves are formed on the outer cable, which not only reduces the wall thickness of this part of the outer cable, but also reduces the locking pressure, promotes stable power connection, enhances the strength of the optical and electrical hybrid cable, and the overall concave-convex structure of the outer cable can strengthen the overall strength of the cable.

[0040] The specific operation process of the present utility model is as follows: directly insert the optical and electrical hybrid cable into the insertion slot of the connector body, align the piercing part of the conductive contact piece with the piercing guide groove of the optical and electrical hybrid cable, turn down the gland, and apply pressure to the optical and electrical hybrid cable by the downward pressing convex block in the gland to pierce it, thereby realizing electrical connection. The optical fiber penetrates into the guiding groove in the center of the connector and is docked with the optical fiber docking assembly, which is controlled by a switch to be turned on.

[0041] The overall structure of the present utility model is simple, and it can quickly and accurately complete the docking of the optical and electrical hybrid cable inserted into the connector, improving the installation efficiency.

[0042] It should be understood that these embodiments are only used to illustrate the present utility model and not to limit the scope of the present utility model. In addition, it should be understood that after reading the content taught by the present utility model, those skilled in the art can make various changes or modifications to the present utility model, and these equivalent forms also fall within the scope defined by the appended claims of this application.
