Detailed Implementation
[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.
[0028] Example 1:
[0029] This utility model provides a self-heating terminal for new energy vehicles. Please refer to [link / reference]. Figure 1-3 The device includes a bottom housing 1 and an upper housing 3. The bottom housing 1 is provided with two sets of wiring assemblies. The top of the upper housing 3 is provided with a heat dissipation hole, which is set as a first heat dissipation hole 31. The inner cavity of the bottom housing 1 is connected to the outside through the first heat dissipation hole 31, thereby realizing the heat dissipation of the wiring assemblies in the bottom housing 1.
[0030] A sealing ring 2 is provided between the bottom housing 1 and the upper housing 3, and a snap-fit structure is installed between the bottom housing 1 and the upper housing 3.
[0031] The buckle structure includes a female buckle 11 integrally provided on the bottom housing 1 and a male buckle 10 integrally provided on the upper housing 3. When the male buckle 10 and the female buckle 11 are engaged, the sealing ring 2 is in a compressed state.
[0032] The top of the upper housing 3 has a protective cover 4, which blocks the first heat dissipation hole 31 and prevents the inner cavity of the bottom housing 1 from being open. The protective cover 4 has through holes evenly distributed on it. With the presence of the through holes on the protective cover 4, the inner cavity of the bottom housing 1 is still connected to the outside.
[0033] The outer wall of the protective cover 4 has an integral fixing block 41. The fixing block 41 and the upper housing 3 are provided with internal threaded holes at corresponding positions. The fixing block 41 and the upper housing 3 are fixed together by bolts.
[0034] The wiring assembly includes a bevel block 5 fixed on the bottom wall of the inner cavity of the bottom housing 1. A fastening threaded pin 7 is threadedly connected to the top of the bevel block 5. A clamping plate 8 is welded to the bottom of the fastening threaded pin 7. The clamping plate 8 is located in the inner cavity of the bevel block 5. A bridging metal plate 9 is integrally provided between the two bevel blocks 5.
[0035] An arc-shaped pressure plate 6 is bolted inside the bottom housing 1. The arc-shaped pressure plate 6 is used to press the wire. When the pressure plate 8 presses the wire core, the pressure plate 8 will not pull on the wire core under the fixing action of the arc-shaped pressure plate 6, thus ensuring the reliability of the wiring.
[0036] In practical use, the upper housing 3 is opened, the wires are stripped and the core is inserted into the orifice block 5. The fastening threaded pin 7 is tightened and the clamping plate 8 is driven to squeeze the core tightly. With the presence of the first heat dissipation hole 31 and the through hole on the protective cover 4, the inner cavity of the bottom housing 1 is connected to the outside, thereby realizing heat exchange and achieving good heat dissipation of the wiring components in the inner cavity of the bottom housing 1.
[0037] Example 2:
[0038] See attached document Figure 4 Unlike Embodiment 1, the top of the bridging metal sheet 9 is welded with a heat dissipation metal sheet 12, and the top of the heat dissipation metal sheet 12 is welded with a heat dissipation rod 121. The heat conduction of the wiring assembly is transferred to the bridging metal sheet 9, and the heat of the bridging metal sheet 9 is transferred to the heat dissipation metal sheet 12 and the heat dissipation rod 121, thereby exchanging heat with the outside air more fully and achieving better heat dissipation of the wiring assembly.
[0039] In practical use, the upper housing 3 is opened, the wires are stripped and the core is inserted into the orifice block 5. The fastening threaded pin 7 is tightened and the clamping plate 8 is driven to squeeze the core tightly. With the presence of the first heat dissipation hole 31 and the through hole on the protective cover 4, the inner cavity of the bottom housing 1 is connected to the outside, thereby realizing heat exchange and achieving good heat dissipation of the wiring components in the inner cavity of the bottom housing 1.
[0040] At the same time, the heat of the wiring assembly is conducted to the bridging metal plate 9, and the heat of the bridging metal plate 9 is conducted to the heat dissipation metal plate 12 and the heat sink 121, so as to exchange heat with the outside air more fully and achieve better heat dissipation of the wiring assembly.
[0041] Example 3:
[0042] See attached document Figure 5 Unlike Embodiment 1, the upper housing 3 has a second heat dissipation hole 32 for the heat dissipation metal sheet 12 to pass through, and a sealing ring is provided between the heat dissipation metal sheet 12 and the second heat dissipation hole 32.
[0043] In practical use, the heat of the wiring assembly is conducted to the bridging metal plate 9, and the heat of the bridging metal plate 9 is conducted to the heat dissipation metal plate 12 and the heat sink 121, thereby exchanging heat with the outside air more fully and achieving better heat dissipation of the wiring assembly.
[0044] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation.
