Description

Technical Field

[0001] This utility model belongs to the field of thermal battery structure design and application, and relates to a fixed structure for multi-channel cable output of thermal batteries. Background Technology

[0002] A thermal battery is a primary storage battery that uses solid molten salt as the electrolyte and has no energy output in its storage state. Upon receiving an activation signal, the heating element is ignited, the electrolyte melts, and the thermal battery begins to operate and output electrical energy. Traditional thermal batteries use wires for both activation signal input and electrical energy output. This involves directly wrapping the wires around the cylindrical terminals on the thermal battery cover or through the flat solder holes of the terminals several times, and then soldering the terminals to securely connect the wires, thus achieving the required input and output. As an ideal power source, thermal batteries are increasingly evolving towards providing multiple outputs from a single power source to power various electronic components simultaneously.

[0003] There are three main types of cable fixing structures for thermal batteries: potting, bracket, and crimping. The potting structure places an insulating washer coaxially with the battery cover between the terminal distribution circle and the outer diameter of the thermal battery cover. The cable is soldered to the terminal, and the cable exits from the outlet of the washer. The cable is then secured by potting compound such as 704 silicone rubber or 914 adhesive within the insulating washer. This type of fixing structure may experience cracking or chipping of the potting compound under harsh mechanical conditions such as acceleration and vibration, leading to cable breakage at the solder joint. The bracket fixing structure secures the soldered cable to the thermal battery cover using a bracket, exposing the cable and making it susceptible to mechanical damage during installation and use. The crimping structure uses a metal clamp with a cable outlet groove to rigidly fix the cable. However, external forces during use may damage the outer insulation of the cable, causing a decrease in internal insulation performance and hindering stable power output. All three cable fixing structures are detrimental to the reliable connection between the thermal battery and the weapon system. Utility Model Content

[0004] This utility model provides a hot battery multi-channel cable output fixing structure that is suitable for stable high-current output and has high reliability, solving the problem that potting fixing structure, bracket fixing structure and crimp fixing structure are not conducive to reliable connection.

[0005] This utility model is achieved through the following technical solution:

[0006] A multi-channel output fixing structure for a thermal battery includes a thermal battery cover, a gasket, a panel, multi-channel output cables, and a cable clip. The battery cover, gasket, and panel are fixedly connected to form a closed cavity. The multi-channel output cables extend from the panel into the cavity and are welded to the terminals on the cover. The cavity is then filled with potting compound. The cable clips are fixed to the multi-channel output cables by connecting to the panel.

[0007] The cover plate is provided with a fixing post, and the fixing post has a threaded hole inside, which is rigidly connected to the washer and the panel by screws.

[0008] The upper surface of the panel has two flat column bosses with through holes, which are rigidly connected to the wire clips by screws.

[0009] The gaskets and panels are made of high-strength, corrosion-resistant, and heat-resistant aluminum alloy.

[0010] The potting compound is an insulating adhesive.

[0011] The wire clip is made of stainless steel.

[0012] The beneficial effects of this utility model are:

[0013] 1. This fixed structure separates the activation signal input and multiple power output circuits, using different colored wires to distinguish the circuits, preventing soldering errors. It outputs power externally through multiple cables, improving the convenience and reliability of thermal battery installation and connection, and increasing the flexibility of use.

[0014] 2. This fixing structure uses cable clips to fix the cable, realizing radial output of the cable, preventing the cable root from being broken or loosened due to bending or external force, thus enhancing the reliability of the line.

[0015] 3. This fixing structure achieves effective potting of insulating adhesive through the enclosed space it forms, thus providing effective insulation protection for the solder joints and initial fixing of the cable.

[0016] 4. This fixing structure rigidly fixes the thermal battery cover, gasket, panel, and wire clamp with screws, improving the reliability of the connection between the thermal battery and the cable.

[0017] 5. The gaskets and panels in this fixed structure are made of aluminum alloy, realizing the lightweight development of thermal batteries. Attached Figure Description

[0018] Figure 1 This is a schematic diagram of the fixed structure of the multi-output cable of the thermal battery. Detailed Implementation

[0019] like Figure 1 As shown, this utility model is a multi-channel cable output fixing structure for a thermal battery, including a thermal battery cover, gaskets, a panel, multi-channel output cables, and cable clips.

[0020] The multi-channel cable output fixing structure of the thermal battery consists of a thermal battery cover, washers, a panel, wire clips, screws, and potting compound. The washers, panel, cover, and wire clips are rigidly fixed together by screws to form a closed space, which is then filled with potting compound.

[0021] The cover consists of a cover plate, a terminal post, a glass body, and a fixing post. The glass body is sintered and sealed to the cover plate. The fixing post has a threaded hole inside and is rigidly fixed to the washer and panel by screws.

[0022] The washer and panel are made of high-strength, corrosion-resistant, and heat-resistant aluminum alloy. The upper part of the panel has two flat column bosses with through holes, which are rigidly fixed to the wire clip by screws.

[0023] The cable clamp is made of stainless steel. The cable passes through the through hole in the middle of the panel and is ejected radially through the cable clamp.

[0024] The potting compound is an insulating compound that provides insulation protection for the solder joints between the terminals and the cable, and also serves to fix the cable in place.

[0026] refer to Figure 1 The multi-channel cable output fixing structure of the thermal battery consists of a thermal battery cover 1, a washer 2, a panel 3, a cable clip 5, potting compound, screws, etc. The thermal battery cover is processed, and there are two fixing posts 10 with threaded holes on the cover 1. Screws 8 are screwed into the fixing posts 10 through the panel 3 and washer 2 in sequence to fix the three together.

[0027] Washer 2 is made of aluminum alloy and has through holes on its sidewalls for rigid connection with screw 8.

[0028] Panel 3 is made of aluminum alloy and has a top part Figure 1 The two flat column bosses 7 with through holes are used to mate with the wire clip 6 and connect via pan head screws 4.

[0029] The line clip 6 is made of stainless steel and has two through holes for mounting pan head screws 4.

[0030] Insert the gasket 2 and panel 3 through the central through-hole into the multi-channel cable 5. After the cable is soldered, fill the hole with 704 silicone rubber. Figure 1 In the enclosed space 9, the solder joints and cables are potted using... Figure 1 The countersunk screw 8 secures the washer 2 and the panel 3 to the cover 1, and finally uses the wire clip 6 and... Figure 1 The pan screw 4 is fixed to the flat post boss 7 on the panel 3, ultimately realizing the radial output of multiple cables.

[0031] The thermal battery with this fixed structure design showed no physical damage after undergoing structural mechanics tests such as transportation vibration and transportation impact, and functional mechanics tests such as overload impact and flight vibration. It can maintain a stable output of electrical energy and fully meet the usage requirements.
