Technical Field
[0001] The utility model relates to the technical field of electronic device clamp machinery, in particular to a combined medium bracket. Background Art
[0002] The media bracket is made of plastic and is divided into two parts: the base and the pillar. Three different specifications of pillars extend from the base. Three different electronic devices are installed on the three specifications of pillars. Different types and quantities of electronic devices combined will produce different index parameters. Therefore, each model of product has a corresponding set of pillar combinations.
[0003] There are many ways to combine the pillars according to the product model. If a mold is made for each type, many sub-molds need to be made, which will greatly increase the cost. At present, the medium bracket is processed by machining according to the model of the order. The cost of a single medium bracket with machining technology is relatively high and the processing cycle is long.
[0004] For example, in the manufacturing and testing process of step attenuators, dielectric brackets are used as the core components for installing reeds. The reeds fixed on the dielectric brackets are of various types, and conventional dielectric brackets cannot meet the installation requirements of all types. In addition, the number of times the reeds are disconnected during their entire life cycle is millions of times, so the size of the support pillars of the dielectric brackets must be very precise, otherwise it will cause abnormal contact and wear of the reeds, thus affecting their lifespan.

[0021] The embodiments of the present utility model are described in detail below in conjunction with the accompanying drawings.
[0022] The utility model provides a combined medium support, which comprises a base, a plurality of pillars and pillar pins.
[0023] like Figures 1 to 3 As shown, taking the configuration of three types of pillars on the base as an example, the product structure, assembly process and working principle are explained in detail.
[0024] 1. Product components and connection relationships:
[0025] The device is mainly composed of a base 1, an A support 2, a B support 3, a C support 4, and a column pin 5. These parts are all made of PPO plastic.
[0026] The bottom of each pillar is provided with a connector 21 of the same specification, the side is provided with an anti-drop convex strip 22, and the top is provided with a mounting seat 23 for mounting electronic devices. The connector 21 includes a left connecting part 211 and a right connecting part 212 arranged opposite to each other. A preset spacing is set between the left connecting part 211 and the right connecting part 212, and an arc groove is set on the opposite side to form a circular channel 213. A plurality of through holes 11 whose shapes match the structure of the connector 21 are provided on the base 1. The connector 21 penetrates each through hole 11. The bottom of the anti-drop convex strip 22 contacts the upper surface of the base 1. The pin 5 is installed in the circular channel 213 and has an interference fit with the circular channel 213.
[0027] 2. Assembly process:
[0028] Select the corresponding number of A pillar 2, B pillar 3, and C pillar 4 according to the product's indicator parameters;
[0029] First, apply resin glue on the A pillar 2, the B pillar 3, and the C pillar 4; then fix the pillars coated with glue into the through holes reserved on the base 1;
[0030] Insert the pin 5 from the bottom of the base 1 into the reserved holes on the A pillar 2, the B pillar 3, and the C pillar 4, i.e., the circular channel of the connecting piece, so that the clearance fit between each pillar and the base 1 is changed to a tight fit; send the assembled medium bracket into the oven for high-temperature curing of the glue, and finally obtain the finished medium bracket.
[0031] 3. Working principle:
[0032] The connecting pieces at the bottom of the A pillar 2, the B pillar 3, and the C pillar 4 form an expandable opening structure, and the center of the opening is a circular hole structure, that is, a circular channel is formed; the diameter of the column pin 5 is slightly larger than the size of the central circular hole of the bottom opening of the pillar; when the column pin 5 is inserted into the circular hole reserved on the pillar, the expansion structure will expand to the side, so that the pillar is tightly fixed to the base 1. After the glue is cured, the risk of loosening and failure of fixation is further eliminated.
[0033] Because the number of A pillars 2, B pillars 3, and C pillars 4 can be flexibly adjusted, the types of pillars to be produced can be accurately controlled in one mold by controlling the on-off of the mold feed flow channel, so open mold injection molding technology can be used, which greatly improves production efficiency and reduces production costs.
[0034] Because the quantity of A pillar 2, B pillar 3, and C pillar 4 can be flexibly adjusted, the utilization rate of parts is improved, the inventory quantity can be reduced, the capital occupation of inventory materials is reduced, and the production cost is reduced.
[0035] Figure 4 The combined medium bracket proposed by the utility model is shown as an example of installing different types of reeds, such as reed one 101, reed two 102, reed three 103, and reed four 104 of different sizes, which are respectively installed on pillars of corresponding sizes.
[0036] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the above embodiments do not limit the utility model in any form, and any technical solution obtained by equivalent replacement or equivalent transformation falls within the protection scope of the utility model.
