Technical Field
[0001] This utility model relates to the field of radio frequency contact technology, and more specifically, to a radio frequency contact device under load. Background Technology
[0002] A radio frequency (RF) relay is an electrical control component that causes a predetermined step change in the controlled quantity in the electrical output circuit when the change in the input quantity (excitation quantity) reaches a specified requirement. RF relays are specifically used for opening and closing, switching RF antenna connections, and a combination of relays is called an RF relay. It has an interactive relationship between the control system and the controlled system. The high-frequency characteristics of RF relays can reduce high-frequency loss compared to other relays, so it plays a role in automatic adjustment, safety protection, and circuit switching in circuits.
[0003] Currently, in relay systems with radio frequency loads, the load is usually designed separately and connected to the load via a moving contact. This design adds a set of moving contact components, resulting in a larger size. Utility Model Content

This invention solves the problem of the large size of the radio frequency load in the contact system of a relay with a radio frequency load.

The channel is located at the bottom of the load cover and communicates with the mounting groove. The third load push rod is fixedly connected to the bottom of the second load push rod and slides with the channel. The RF load is fixedly connected between the left and right inner walls of the third load push rod and moves through the channel to the lower side of the bottom cover.
[0009] Preferably, each set of moving contact mechanisms includes a moving contact, a moving contact push rod, a guide rod, a guide hole, a spring groove, a second spring, a sleeve rod, and a connecting rod. The spring groove is located at the bottom of the bottom cover. The second spring is fixedly connected to the lower inner wall of the spring groove. The sleeve rod is located inside the second spring. The connecting rod is located on the upper side of the second spring and is fixedly connected to the top of the sleeve rod. There are two guide holes, both located at the top of the bottom cover and symmetrically arranged about the spring groove. There are two guide rods, both fixedly connected to the bottom of the connecting rod. The two guide rods movably pass through the guide holes and extend to the lower side of the bottom cover.

[0014] Compared with the prior art, the advantages of this invention are: Because the load mechanism of this invention is an integral movable design, it can cleverly realize the connection and separation between the radio frequency load and the stationary contact, so there is no need to design an additional load mechanism separately, which can greatly reduce the size of the relay.
[0015] This invention facilitates the connection between the RF load and the stationary contact. When the electromagnet on the right is braked, it generates a strong magnetic force that pushes the top right side of the spring to be attracted upwards, thus pushing the spring to rotate counterclockwise. During the counterclockwise rotation of the spring, the bottom left side of the spring will gradually press the first load push rod downwards. The first load push rod, through the second and third load push rods, pushes the RF load downwards, ultimately achieving contact between the RF load and the stationary contact, thereby achieving the connection between the RF load and the stationary contact. The RF signal is transmitted to the RF load. During the downward movement of the second load push rod, the first spring is gradually compressed, changing it from its initial state to a compressed state.
[0016] This invention facilitates the connection between the moving and stationary contacts. When the electromagnet on the left brakes and the electromagnet on the right stops, the strong magnetic force generated pushes the top left side of the spring sheet upward, causing it to rotate clockwise. During this clockwise rotation, the first spring needs to reset. Under its good elasticity, the first spring causes the RF load to gradually move upward until it resets, separating the RF load from the stationary contact. Simultaneously, the bottom right side of the spring sheet gradually presses the moving contact push rod downward. The moving contact push rod, through the connecting rod and two guide rods, pushes the three moving contacts downward, ultimately achieving contact between the two moving contacts on both sides and the two stationary contacts, thus connecting the moving and stationary contacts. The RF signal is transmitted to the working system. During the downward movement of the connecting rod, the second spring is gradually compressed, changing it from its initial state to a compressed state, facilitating the reset of the moving contact after the other electromagnet brakes.

[0021] Example: Please see Figure 1-3 A loaded radio frequency contact device, comprising: The frame mechanism 100 specifically includes a top cover 110, connecting columns 120, and a bottom cover 130. There are three connecting columns 120, all of which are fixedly connected to the bottom of the top cover 110 and are equidistant from each other. The bottom cover 130 is fixedly connected to the bottom of the three connecting columns 120, and an accommodating space is formed between adjacent connecting columns 120. In this embodiment: the top cover 110 and the bottom cover 130 are connected by three connecting posts 120; Two sets of snap-fit transmission mechanisms 200 are provided, and the two sets of snap-fit transmission mechanisms 200 are symmetrically arranged on the frame mechanism 100. The two sets of snap-fit transmission mechanisms 200 are respectively arranged in two accommodating spaces. Specifically, each set of snap-fit transmission mechanisms 200 includes a rotating mounting base 210, a rotating shaft 220, a pushing spring 230, and an electromagnet 240. The rotating mounting base 210 is fixedly connected to the bottom of the top cover 110, the rotating shaft 220 is rotatably connected to the front end of the rotating mounting base 210, the pushing spring 230 is fixedly connected to the circumferential surface of the rotating shaft 220, and two electromagnets 240 are provided. The two electromagnets 240 are fixedly connected to the bottom of the top cover 110, and the two electromagnets 240 are symmetrically arranged on the left and right sides of the rotating mounting base 210. In this embodiment: the rotating mounting base 210 is used to mount the rotating shaft 220, and the push spring 230 can rotate around the rotating shaft 220. When the braking electromagnet 240 is activated, the electromagnet 240 generates a strong magnetic force, which can attract the top of the push spring 230. Since two electromagnets 240 are provided in each set of snap-action transmission mechanisms 200, the top left and right sides of the push spring 230 can be attracted respectively. By simply braking the left and right electromagnets 240 respectively, the push spring 230 can be rotated clockwise or counterclockwise. It should be noted that the push spring 230 should be made of a material that can be attracted by the electromagnet 240. The first interface 400, the second interface 500, and the third interface 600 are connected to the frame mechanism 100 through a limiting installation mechanism 300 to achieve installation. Specifically, the limiting installation mechanism 300 includes a first limiting installation block 310, a second limiting installation block 320, a third limiting installation block 330, and a fourth limiting installation block 340. The first limiting installation block 310 and the fourth limiting installation block 340 are respectively fixedly connected to the bottom left and right sides of the bottom of the bottom cover 130. The first interface 400 is fixedly connected to the right end of the first limiting installation block 310, the second limiting installation block 320 is fixedly connected to the right end of the first interface 400, the second interface 500 is fixedly connected to the right end of the second limiting installation block 320, the third limiting installation block 330 is fixedly connected to the right end of the second interface 500, and the third interface 600 is fixedly connected between the right end of the third limiting installation block 330 and the left end of the fourth limiting installation block 340. In this embodiment: the first interface 400, the second interface 500, and the third interface 600 are used to transmit radio frequency signals; A first gap is provided between the second limiting mounting block 320 and the third limiting mounting block 330 and the bottom cover 130, and a second gap is provided between the three stationary contacts 800 and the bottom cover 130. In this embodiment: the setting of the first gap and the second gap is necessary, because pushing is required later, so this setting is to reserve space for pushing; There are three stationary contacts 800, and the three stationary contacts 800 are located in the first interface 400, the second interface 500 and the third interface 600 respectively. The three stationary contacts 800 are fixed to the inner walls of the first interface 400, the second interface 500 and the third interface 600 respectively by multiple connecting blocks 700. The bottom of each of the three stationary contacts 800 is provided with a slot 810. In this embodiment: the stationary contact 800 is installed with the first interface 400, the second interface 500 and the third interface 600 through the connecting block 700. With the above settings, the three stationary contacts 800 can be respectively set in the first interface 400, the second interface 500 and the third interface 600. Two sets of load mechanisms 900 are provided, and two sets of interlocking transmission mechanisms 200 are symmetrically arranged on the frame mechanism 100. The two sets of load mechanisms 900 are respectively arranged in two receiving spaces. The interlocking transmission mechanism 200 drives the load mechanism 900 to move downward to connect the load mechanism 900 with one of the stationary contacts 800. Specifically, each load mechanism 900 includes a load cover 910, a mounting hole 920, a sliding hole 930, a mounting groove 940, a channel 950, a first load push rod 960, a second load push rod 970, a first spring 980, a third load push rod 990, and an RF load 9010. The mounting hole 920 is opened on the top of the bottom cover 130, and the load cover 910 is fixedly connected to the top of the bottom cover 130. The sliding hole 930 is opened on the top of the load cover 910, and the mounting groove 940 is opened inside the load cover 910. Hole 930 is connected, first load push rod 960 is slidably connected between the inner walls of the sliding hole 930, and the bottom of the first load push rod 960 extends into the mounting groove 940, second load push rod 970 is fixedly connected to the bottom of the first load push rod 960, and the second load push rod 970 is located inside the mounting groove 940, first spring 980 is fixedly connected between the bottom of the second load push rod 970 and the lower inner wall of the mounting groove 940, channel 950 is opened at the bottom of load cover 910, and channel 950 is connected to mounting groove 940, third load push rod 990 is fixedly connected to the bottom of second load push rod 970, and third load push rod 990 and channel 950 are slidably engaged, RF load 9010 is fixedly connected between the left and right inner walls of third load push rod 990, and RF load 9010 moves through channel 950 and extends to the lower side of bottom cover 130; In this embodiment: the first load push rod 960 can move up and down on the inner wall of the sliding hole 930, and the second load push rod 970 can slide up and down on the inner wall of the channel 950. The setting of the first spring 980 is necessary, and its good elastic force allows the radio frequency load 9010 to be reset. Here, the working principle of the left-side snap-action transmission mechanism 200 is described: when the electromagnet 240 on the right side is braked, it generates a strong magnetic force that pushes the top right side of the spring 230 upward, thus pushing the spring 230 to rotate counterclockwise. During the counterclockwise rotation of the spring 230, the bottom left side of the spring 230 will gradually press the first load push rod 960 downward. The load push rod 960 pushes the RF load 9010 downward through the second load push rod 970 and the third load push rod 990, ultimately achieving contact between the RF load 9010 and the stationary contact 800, thereby establishing a connection between the RF load 9010 and the stationary contact 800. The RF signal is transmitted to the RF load 9010. During the downward movement of the second load push rod 970, the first spring 980 is gradually compressed, changing it from its initial state to a compressed state. Since the load mechanism 900 is an integral movable design, the connection and separation between the RF load 9010 and the stationary contact 800 can be cleverly achieved. Therefore, there is no need to design an additional load mechanism 900 separately, which can greatly reduce the size of the relay. Two sets of moving contact mechanisms 1000 are provided, symmetrically arranged on the frame mechanism 100. Each set is housed within a different receiving space. A snap-action transmission mechanism 200 drives the moving contact mechanism 1000 downwards to connect it with two stationary contacts 800. Specifically, each moving contact mechanism 1000 includes a moving contact 1010, a moving contact push rod 1020, a guide rod 1030, a guide hole 1040, a spring groove 1050, a second spring 1060, a sleeve rod 1070, and a connecting rod 1080. The spring groove 1050 is located at the bottom of the bottom cover 130. The second spring 1060 is fixedly connected to the lower inner wall of the spring groove 1050. The sleeve rod 1070 is located inside the second spring 1060. The connecting rod 1080 is located above the second spring 1060. The top of the sleeve rod 1070 is fixedly connected to the bottom cover 130. Two guide holes 1040 are provided, both of which are opened on the top of the bottom cover 130 and are symmetrically arranged about the spring groove 1050. Two guide rods 1030 are provided, both of which are fixedly connected to the bottom of the connecting rod 1080 and are respectively movably passed through the guide holes 1040 and extended to the lower side of the bottom cover 130. Three moving contacts 1010 are provided. One moving contact 1010 is fixedly connected to the left end of one of the guide rods 1030, another moving contact 1010 is fixedly connected between the two guide rods 1030, and the last moving contact 1010 is fixedly connected to the right end of the other guide rod 1030. The three moving contacts 1010 are parallel to each other and are all located on the lower side of the bottom cover 130. In this embodiment: the spring groove 1050 is provided to realize the installation of the second spring 1060. This setting is necessary. The second spring 1060 has good elastic force, which allows the moving contact 1010 to reset after downward movement. Through the mutual cooperation between the guide rod 1030 and the guide hole 1040, it has good guiding properties when moving upward or downward. Here, the working principle of the left-side snap-action transmission mechanism 200 is described: when the electromagnet 240 on the left brakes and the electromagnet 240 on the right stops, it generates a strong magnetic force that pushes the top left side of the spring piece 230 upward, thus pushing the spring piece 230 to rotate clockwise. During the clockwise rotation of the spring piece 230, since the first spring 980 needs to reset, under its good elastic force, the first spring 980 causes the RF load 9010 to gradually move upward until it resets, realizing the connection between the RF load 9010 and the spring piece 2060. As the stationary contact 800 separates, the bottom right side of the push spring 230 gradually presses the moving contact push rod 1020 downward. The moving contact push rod 1020 pushes the three moving contacts 1010 downward through the connecting rod 1080 and the two guide rods 1030, ultimately achieving contact between the two moving contacts 1010 on both sides and the two stationary contacts 800, thereby achieving the connection between the moving contacts 1010 and the stationary contacts 800. The radio frequency signal is transmitted to the working system. During the downward movement of the connecting rod 1080, the second spring 1060 is gradually compressed, changing it from the initial state to the compressed state, which facilitates the subsequent braking of the other electromagnet 240 and the reset of the moving contact 1010. It should be noted that the moving contact 1010 is electrically connected to the working system (not shown in the figure). The working system is not the technical problem that this invention needs to solve, and a working system that can be achieved by conventional means can be used. Therefore, it will not be described in detail. The working principle or process of this invention is described here, focusing only on the working principle of the set of interlocking transmission mechanisms 200 located on the left side: When the electromagnet 240 on the right side is braked, it generates a strong magnetic force that pulls the top right side of the spring 230 upward, thus pushing the spring 230 to rotate counterclockwise. During the counterclockwise rotation of the spring 230, the bottom left side of the spring 230 gradually presses the first load push rod 960 downward. The first load push rod 960, through the second load push rod 970... The third load push rod 990 pushes the RF load 9010 downwards, ultimately achieving contact between the RF load 9010 and the stationary contact 800, thus establishing a connection between the RF load 9010 and the stationary contact 800. The RF signal is then transmitted to the RF load 9010. During the downward movement of the second load push rod 970, the first spring 980 is gradually compressed, changing it from its initial state to a compressed state. When the electromagnet 240 on the left brakes and the electromagnet 240 on the right stops, the resulting strong magnetic force pushes the first load 9010 downwards. The top left side of the movable spring 230 is attracted upwards, thus pushing the spring 230 to rotate clockwise. During the clockwise rotation of the spring 230, the first spring 980 needs to reset. Therefore, under the action of its good elastic force, the first spring 980 causes the RF load 9010 to gradually move upwards until it resets, realizing the separation of the RF load 9010 from the stationary contact 800. At the same time, the bottom right side of the spring 230 gradually pushes the movable contact push rod 1020 downwards. The movable contact push rod 1020 is connected to the connecting rod. 1080 and two guide rods 1030 push the three moving contacts 1010 downwards, ultimately achieving contact between the two moving contacts 1010 on both sides and the two stationary contacts 800 respectively, thereby achieving the connection between the moving contacts 1010 and the stationary contacts 800. The radio frequency signal is transmitted to the working system. During the downward movement of the connecting rod 1080, the second spring 1060 will be gradually compressed, changing it from the initial state to the compressed state, so that after the other electromagnet 240 is braked, the moving contact 1010 can be reset.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and its improved concept, should be covered within the scope of protection of the present invention.
