Description

Technical Field

[0001] The utility model relates to the technical field of signal reception, in particular to a connection structure of a high-frequency head. Background Technique

[0002] People's beautiful wishes will all come true after ultimate efforts, and the same is true for the mobile reception of satellite TV signals. It has changed from an ideal to a reality. It can not only receive TV signals from other places and countries, but also can be received mobilely in a vehicle or on a ship. The high-frequency head, commonly known as a tuner, is a device used by a set-top box to receive high-frequency signals and demodulate video information, and is also the first part of the common channel. At present, the high-frequency heads used in set-top boxes are generally divided into digital signal high-frequency heads (abbreviated as digital high-frequency heads) and analog signal high-frequency heads (abbreviated as analog high-frequency heads). Simply put, the tuner for receiving TV signals and the high-frequency signal amplifier will gradually be replaced by digital signal high-frequency heads due to the development of electronic technology.

[0003] Traditional high-frequency heads are often exposed to the wind and sun when set outside, resulting in a short service life and high costs. Moreover, they are installed and fixed. If one of the parts is damaged, the whole needs to be replaced, increasing the economic pressure on people. Traditional high-frequency heads can only receive and output signal waves of a fixed frequency. If you want to receive signals of other frequencies, you must replace the high-frequency head. Traditional high-frequency heads are easily affected by external electromagnetic interference. After a long-distance signal transmission, the signal itself is already very weak, and it is almost impossible to work normally after being interfered. For this reason, we propose a connection structure of a high-frequency head to solve the above problems. Content of the Utility Model

A sleeve is slidably sleeved on the outer surface of the metal shell, and the metal shell can slide inside the sleeve. Four conduction blocks are fixedly installed on the inner surface of the side of the sleeve away from the metal shell, and the other end of the conduction block is in contact with the outer surface of the copper block. An output end is fixedly installed on the outer surface of the sleeve near the conduction block, one end of the output end is fixedly connected to the outer surface of the conduction block, a receiving head is fixedly installed on the outer surface of the copper block at the end away from the output end, and an input end is movably installed outside the receiving head.

[0006] Preferably, slots are provided at relative positions on the outer surface of the input end, and insertion blocks are fixedly installed at relative positions on the outer surface of the receiving head. The insertion blocks are movably clamped in the slots, and the input end can be used in cooperation with each receiving head.

[0024] 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 the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0025] Embodiment: As Figure 1-6As shown in the figure, the present utility model provides a high-frequency head connection structure, including a metal shell 1. Inside the metal shell 1, there is a chip 2. By setting the metal shell 1, it is convenient to shield the external electromagnetic signals and reduce the possibility of incorrect operations caused by interference. At both ends of the chip 2, four groups of symmetrically and evenly distributed wires 4 are fixedly installed. On the opposite sides of the wires 4, copper blocks 5 are fixedly installed, and the copper blocks 5 are fixedly installed on the outer surfaces at both ends of the metal shell 1. By setting the fixed installation of the wires 4 and the copper blocks 5, it is convenient to make the input and output signals more complete and faster. A sleeve 3 is slidably sleeved on the outer surface of the metal shell 1, and the metal shell 1 can slide within the sleeve 3. By setting the sleeve 3 to be slidably sleeved on the outer surface of the metal shell 1, it is convenient for the metal shell 1 and the components it carries to slide within the sleeve 3, thereby achieving the purpose of conveniently replacing the metal shell 1, the chip 2, and the parts they carry. On the inner surface of one side of the sleeve 3 away from the metal shell 1, four conduction blocks 301 are fixedly installed, and the other ends of the conduction blocks 301 are in contact with the outer surfaces of the copper blocks 5. By setting the fixed connection between the conduction blocks 301 and the sleeve 3, it is convenient for the output signals not to be blocked by the sleeve 3. On the outer surface of the sleeve 3 near one end of the conduction blocks 301, an output terminal 8 is fixedly installed, and one end of the output terminal 8 is fixedly connected to the outer surface of the conduction block 301. By setting the fixed connection between the output terminal 8 and the conduction block 301, it is convenient for the whole part to be welded to other circuit boards, thereby achieving a wider application range. On the outer surface of the copper block 5 at one end away from the output terminal 8, a receiving head 6 is fixedly installed, and an input terminal 7 is movably installed outside the receiving head 6. By setting the receiving head 6 to be fixedly connected to the outer surface of the copper block 5 and the input terminal 7 provided on one side of the receiving head 6, it is convenient for the input terminal 7 to change the access frequencies of different receiving heads 6 and for the device to change various output signal frequencies.

[0026] At the relative positions on the outer surface of the input terminal 7, slots 701 are provided. At the relative positions on the outer surface of the receiving head 6, insertion blocks 601 are fixedly installed, and the insertion blocks 601 are movably clamped in the slots 701. The input terminal 7 can be used in cooperation with each receiving head 6. By setting the cooperation of the slots 701 and the insertion blocks 601, it is convenient to ensure the stability when the input terminal 7 is connected to the receiving head 6 and prevent it from falling off easily.

[0027] On the outer surface of the sleeve 3 on the side away from the output terminal 8, symmetric fixing frames 10 are fixedly installed, and screws 1001 are movably inserted through one end of the fixing frames 10.

[0028] On one side of the sleeve 3 away from the output end 8, there is a fixing plate 11 which is slidably clamped inside the fixing frame 10. By arranging the fixing frame 10 fixedly installed at one end of the sleeve 3, it is convenient for the fixing plate 11 to slide inside the fixing frame 10. By arranging the screw 1001 to pass through the fixing frame 10 movably, it is convenient to limit the position of the fixing plate 11, so that the whole part is more stable and not easy to fall off.

[0029] Inside the input end 7, there is a spring 702 movably clamped. One end of the spring 702 is fixedly installed on the inner surface of the input end 7, and the other end of the spring 702 abuts against one end surface of the receiving head 6. By arranging the spring 702 fixedly installed on one side inner surface of the input end 7, it is convenient for the receiving head 6 to be clamped more firmly by the insertion block 601 when cooperating with the input end 7, reducing the possibility of falling off.

[0030] On the outer surface of one side of the input end 7 away from the receiving head 6, a frequency line 9 is fixedly installed.

[0031] In the middle of the inner surface of the receiving head 6, a receiving line 602 is fixedly installed. When the receiving head 6 is inserted into the corresponding position of the input end 7, the receiving line 602 abuts against one end of the frequency line 9.

[0032] In the middle of the upper surface of the sleeve 3, a heat dissipation block 12 is fixedly installed. By arranging the heat dissipation block 12, it is prevented that the whole part overheats, resulting in signal output interruption or incompleteness.

[0033] Working principle: When in use, first fixedly install the bottom end of the larger area side of the sleeve 3 on the required circuit board, and then correspondingly weld the output end 8 of the part on the receiving circuit of the circuit board. After waiting for the welding to be firm, loosen the screw 1001 and then slide the fixing plate 11 to the maximum limit on both sides. Then insert the metal shell 1 and its internal chip 2 until they are completely fitted. Then pull the fixing plate 11 back to its original position and tighten the screw 1001 to prevent the metal shell 1 from falling off;

[0034] Among them, when input frequency is required, align the open end of the slot 701 with the insertion block 601, and then press the input end 7 towards the receiving head 6 until it is pressed to the maximum limit of the slot 701. Then rotate the input end 7 until it can no longer be rotated and then let go. At this time, the input end 7 is tightly sleeved on the insertion block 601 under the push of the spring 702, so it is not easy to fall off;

[0035] Among them, if different transmission frequencies are required, connect the input end 7 to different receiving heads 6. When the signal passes through the chip 2, it is amplified and its output frequency is changed. Then the signal is transmitted to the output end 8 and then conducted to the circuit board by the output end 8.

[0036] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
