Description

Technical Field

[0001] The utility model relates to the technical field of combiners, in particular to a combined combiner. Background Art

[0002] A combiner is a type of frequency component, mainly used to combine multi-system signals into a set of indoor distribution systems. In engineering applications, it is necessary to combine the 800 MHz C network and the 900 MHz G network frequencies for output. By using a combiner, a set of indoor distribution systems can work in the CDMA frequency band and the GSM frequency band simultaneously; for another example, in a radio antenna system, after combining the input and output signals of several different frequency bands (such as 145 MHz and 435 MHz) through a combiner, a feeder is used to connect to the radio station. This not only saves a feeder but also avoids the trouble of switching different antennas.

[0003] The prior art such as the utility model with the publication number of CN219046320U discloses a combined combiner. This patent uses a base and also includes a clamping and limiting mechanism movably connected to the base; a carrying mechanism connected to the base. The carrying mechanism includes a support frame and a connecting block fixedly connected to the base. The support frame and the connecting block are jointly fixedly connected with a support seat. The support seat is fixedly connected with a limiting frame. Two sets of combiner limiting structures are movably connected to the limiting frame. One set of combiner limiting structures is connected to the limiting frame through an elastic lifting structure. The equipment of the utility model solves the problem that the types of existing combiners are increasing, and in communication applications, there are often situations where multiple combiners need to be used in combination. However, the existing combiners used in combination are mostly installed side by side, and the structural dimensions of the existing combiners used in combination need to be the same, resulting in limited application scope of the existing combiners used in combination.

[0004] In daily work, during the use of the equipment, there is a problem that when the plug is connected to the connecting head, it is easy to rotate and separate from the surface of the connecting head, making it difficult for the plug and the connecting head to be tightly connected, resulting in signal interruption and making it difficult for the equipment to work properly. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a combined combiner to solve the drawback that the plug is easily separated from the connecting head in the prior art.

[0006] To achieve the above object, the utility model adopts the following technical solutions: A combined duplexer includes a main body, a connector, a communicating head, a plug, and an anti - detachment device. A connector is fixedly connected to the side surface of the main body, and a communicating head is fixedly connected to the side surface of the main body. The plug is inserted and connected to the surface of the communicating head. The anti - detachment device is arranged on the surface of the communicating head. The anti - detachment device includes a first connecting block and a second connecting block. The first connecting block is fixedly connected to the surface of the plug, and the second connecting block is fixedly connected to the surface of the communicating head. A card slot is formed on the surface of the first connecting block, and a pulling slot is formed on the surface of the second connecting block. A clamping plate is slidably connected to the inner wall of the pulling slot, and the clamping plate is clamped with the inner wall of the card slot. One end of the clamping plate away from the card slot is fixedly connected to a first spring, and one end of the first spring away from the clamping plate is fixedly connected to the inner wall of the pulling slot.

[0007] Further, a sliding rod is slidably connected to the inner wall of the second connecting block. One end of the sliding rod is fixedly connected to a resisting block. By setting the sliding rod, the limiting movement of the resisting block can be realized, reducing the situation that when the device is in use, the resisting block is prone to shaking during movement, making it difficult for the resisting block to move the clamping plate.

[0008] Further, one end of the resisting block abuts against the surface of the clamping plate, and a limiting block is fixedly connected to the end of the sliding rod away from the resisting block. The setting of the limiting block facilitates the limiting of the sliding rod.

[0009] Further, a second spring is sleeved on the surface of the sliding rod, and both ends of the second spring are fixedly connected to the surface of the limiting block and the surface of the second connecting block respectively. The setting of the second spring facilitates the application of a reset elastic force to the sliding rod.

[0010] Further, a protection device is arranged on the side surface of the communicating head. The protection device includes a connecting arm and a support ring. The connecting arm is fixedly connected to the side surface of the communicating head, and one end of the connecting arm is fixedly connected to a support ring. A protection ring is rotatably connected to the surface of the support ring. A sliding groove is formed on the side surface of the support ring, and a limiting groove is formed on the side surface of the protection ring. By setting the protection ring, the wire can be limited and protected, reducing the situation that when the device is in use, the connection part between the wire and the plug is prone to breakage and damage.

[0011] Further, a clamping rod is slidably connected to the inner wall of the sliding groove, and one end of the clamping rod is clamped inside the limiting groove. The setting of the clamping rod facilitates the limiting of the protection ring.

[0012] Further, one end of the clamping rod away from the limiting groove is fixedly connected to a third spring, and one end of the third spring away from the clamping rod is fixedly connected to the inner wall of the sliding groove. The setting of the third spring facilitates the application of a reset elastic force to the clamping rod.

[0013] Compared with the prior art, the advantages and positive effects of the present utility model are as follows:

[0014] 1. In the present utility model, when the device is in use, the user connects the signal to be connected to the connecting head, and then combines multiple signals and outputs them together. When the device is in use, the abutting block is pushed, and then the sliding rod moves when the abutting block moves. When the sliding rod moves, the second spring is displaced and deformed to generate elastic force. Then, the abutting block moves to push the clamping plate to move. When the clamping plate moves, the first spring is displaced and deformed to generate elastic force. Then, the clamping plate disengages from the inside of the clamping groove, and then the plug is no longer restricted. By setting the anti-disconnection device, the plug is effectively limited, playing a role in positioning and restricting the plug, reducing the situation that when the device is in use, the plug is prone to rotate and disengage from the surface of the connecting head during the connection between the plug and the connecting head, resulting in difficult tight connection between the plug and the connecting head, signal interruption, and abnormal use of the device, and improving the stability of the device.

[0015] 2. In the present utility model, by setting the protection device, when the device is in use, the user pulls the clamping rod, and then the clamping rod moves to drive the third spring to be displaced and deformed to generate elastic force. Then, the clamping rod moves out of the inside of the limiting groove, and then the protection ring is no longer restricted. The protection ring is rotationally connected on the surface of the support ring by rotating, and then the protection ring disengages from the surface of the plug wire. By setting the protection device, the connection between the wire and the plug is effectively protected, playing a role in protecting the plug wire, reducing the situation that when the device is in use, the connection between the wire and the plug is prone to folding, which is likely to cause damage to the connection between the wire and the plug, and improving the practicability of the device.

[0022] Please refer to Figures 1 - 5 , the present utility model provides a technical solution: a combined duplexer, including a main body 1, a connector 2, a connecting head 3, a plug 4 and an anti - detachment device 5.

[0023] Next, specifically describe the specific settings and functions of its anti - detachment device 5 and protection device 6.

[0024] In this implementation: The anti - detachment device 5 is arranged on the surface of the connecting head 3. The anti - detachment device 5 includes a first connecting block 51 and a second connecting block 52. The first connecting block 51 is fixedly connected to the surface of the plug 4, the second connecting block 52 is fixedly connected to the surface of the connecting head 3. A card slot 53 is formed on the surface of the first connecting block 51, a pulling slot 54 is formed on the surface of the second connecting block 52. A card plate 55 is slidably connected to the inner wall of the pulling slot 54, and the card plate 55 is clamped with the inner wall of the card slot 53. One end of the card plate 55 away from the card slot 53 is fixedly connected to a first spring 56, and the end of the first spring 56 away from the card plate 55 is fixedly connected to the inner wall of the pulling slot 54.

[0025] Specifically, a slide bar 58 is slidably connected to the inner wall of the second connecting block 52, and a block 57 is fixedly connected to one end of the slide bar 58.

[0026] In this embodiment: By setting the slide bar 58, the limit movement of the block 57 can be carried out, reducing the situation that when the device is in use, the block 57 is prone to shaking during movement, making it difficult for the block 57 to move the card plate 55.

[0027] Specifically, one end of the block 57 abuts against the surface of the card plate 55, and a limit block 59 is fixedly connected to the end of the slide bar 58 away from the block 57. The limit block 59 is provided to facilitate the limit of the slide bar 58.

[0028] Specifically, a second spring 510 is sleeved on the surface of the slide bar 58, and both ends of the second spring 510 are fixedly connected to the surface of the limit block 59 and the surface of the second connecting block 52 respectively. The second spring 510 is provided to facilitate applying a reset elastic force to the slide bar 58.

[0029] In this implementation: A protective device 6 is provided on the side of the connecting head 3. The protective device 6 includes a connecting arm 61 and a support ring 63. The connecting arm 61 is fixedly connected to the side of the connecting head 3. One end of the connecting arm 61 is fixedly connected to a support ring 63. A protective ring 62 is rotatably connected to the surface of the support ring 63. A chute 64 is provided on the side of the support ring 63, and a limiting groove 65 is provided on the side of the protective ring 62.

[0030] In this embodiment: By providing the protective ring 62, the electric wire can be limited and protected, reducing the situation that the connection between the electric wire and the plug 4 is prone to breakage and damage when the device is in use.

[0031] Specifically, a clamping rod 66 is slidably connected to the inner wall of the chute 64. One end of the clamping rod 66 is clamped inside the limiting groove 65. The setting of the clamping rod 66 facilitates the limitation of the protective ring 62.

[0032] Specifically, one end of the clamping rod 66 away from the limiting groove 65 is fixedly connected to a third spring 67. The end of the third spring 67 away from the clamping rod 66 is fixedly connected to the inner wall of the chute 64. The setting of the third spring 67 facilitates applying a reset elastic force to the clamping rod 66.

[0033] Working principle: When the device is in use, the user connects the signal to be connected to the connecting head 3, and then combines multiple signals and outputs them together. When the device is in use, the abutting block 57 is pushed, and then when the abutting block 57 moves, it drives the sliding rod 58 to move. When the sliding rod 58 moves, it drives the second spring 510 to displace and deform to generate an elastic force. Then the abutting block 57 moves to push the clamping plate 55 to move. When the clamping plate 55 moves, it drives the first spring 56 to displace and deform to generate an elastic force. Then the clamping plate 55 disengages from the inside of the card slot 53, and then the plug 4 is released from the restraint. By providing the anti-disconnection device 5, the plug 4 is effectively limited, playing a role in positioning and restricting the plug 4, reducing the situation that when the device is in use, the connection between the plug 4 and the connecting head 3 is prone to rotate and disengage from the surface of the connecting head 3, resulting in the plug 4 and the connecting head 3 being difficult to be tightly connected, causing signal interruption and the device being difficult to be used normally, and improving the stability of the device.

[0034] When the device is in use, the user pulls the clamping rod 66. Then when the clamping rod 66 moves, it drives the third spring 67 to displace and deform to generate an elastic force. Then the clamping rod 66 moves out of the inside of the limiting groove 65, and then the protective ring 62 is released from the restraint. The protective ring 62 is rotatably connected on the surface of the support ring 63 by rotating, and then the protective ring 62 disengages from the surface of the electric wire of the plug 4. By providing the protective device 6, the connection between the electric wire and the plug 4 is effectively protected, playing a role in protecting the electric wire at the plug 4, reducing the situation that when the device is in use, the connection between the electric wire and the plug 4 is prone to folding, which is likely to cause damage to the connection between the electric wire and the plug 4, and improving the practicability of the device.
