Description

Technical Field

[0001] The invention belongs to the technical field of cables, and in particular relates to a high-power connector with a heat dissipation structure. Background Art

[0002] In the use of cluster connectors, due to the continuous increase in RF signal power and the cluster structure of the interface, multiple signal channels are integrated in the same interface. When using high-power transmission, the connector actually withstands 4-5 times the power operation. With the increase in power, the connector structure also generates heat continuously, and the temperature will exceed 125°C at the limit. In actual construction, after the cluster connector is connected to the interface, it is necessary to use glue to wrap it for waterproofing, which makes the heat accumulated inside the connector have no space to dissipate. The heat continues to accumulate. Under the condition of high-power continuous operation, it will cause direct damage to the RF interface and the supporting cable, and even cause the entire cluster connector assembly to be scrapped.

This summary is not an exhaustive overview of all conceived aspects, and is neither intended to identify the key or critical elements of all aspects nor to define the scope of any or all aspects. Its only purpose is to give some concepts of one or more aspects in a simplified form as a prelude to a more detailed description that will be given later.

[0027] like Figure 1-9 As shown, a high-power connector with a heat dissipation structure includes a cluster connector body 1, a coaxial cable 2 and a heat dissipation structure. There are several coaxial cables 2 and they are all arranged on the cluster connector body 1. The heat dissipation structure includes several heat-conducting rods 3 for transferring heat. The heat-conducting rods 3 are made of materials with high thermal conductivity coefficients such as metal. One end of the heat-conducting rod 3 is arranged on the cluster connector body 1, and the other end thereof is suspended and provided with several heat dissipation fins 4 at the end for increasing the contact area with the air and facilitating heat dissipation. The heat generated by the connector is transferred to the heat dissipation fins 4 through the heat-conducting rods 3, so as to realize heat transfer and heat dissipation, avoid heat accumulation affecting the normal use of the device, and help to improve the service life of the device.

[0028] In some embodiments, in order to improve the heat dissipation capacity, a gap is provided inside the heat conducting rod 3 for the flow of coolant. After the coolant is filled inside, all assembly gaps are welded and sealed.

[0029] In some specific embodiments, the core rod 5 can be inserted into the heat conducting rod 3, and a gap is left between the inner wall of the heat conducting rod 3 and the outer wall of the core rod 5 therein, and the gap is filled with coolant. A limit step 51 is provided at the head of the core rod 5 to play a role of limiting, so that the core rod 5 is not completely embedded in the heat conducting rod 3. A plurality of through holes 52 are provided at the head of the core rod 5, and the core rod 5 is preferably designed as an internal hollow structure from the position of the through hole 52 to the tail. The opening inside the tail of the core rod 5 is in a trumpet shape, which facilitates the flow of coolant to the center, so that the inside of the core rod 5 is connected to the gap through the through hole 52 and the trumpet. A plurality of protrusions 53 are provided at intervals along the circumferential direction on the outside of the tail of the core rod 5, which are used to support the inside of the heat conducting rod 3 and prevent tilting. A guide 6 is provided inside the end of the suspended end of the heat conducting rod 3. The heat conducting rod 3, the core rod 5, and the guide 6 are coaxially arranged. The guide 6 has a central protrusion and is in an arc shape around it, which is used to guide the flow direction of the coolant. When the core rod 5 is inserted into the heat-conducting rod 3, it is limited by the limiting step 51, the through hole 52 is located in the gap surrounded by the heat-conducting rod 3 and the core rod 5, the inside of the core rod 5 is connected with the gap, the protrusion 53 contacts the inner wall of the heat-conducting rod 3, and the coolant can circulate in the gap, the core rod 5, and the guide member 6.

[0030] During use, when the cluster connector body 1 is heated, the coolant expands due to the heat and flows to the suspended end of the heat conducting rod 3. After cooling at the heat dissipation fins 4, it flows back from the suspended end, enters the core rod 5 from the bell mouth at the tail of the core rod 5, flows to the head of the heat conducting rod 3, and then flows out from the through hole 52 at the head of the core rod 5, forming a circular flow. Fig. 9 The red arrow in the middle indicates the flow direction of the coolant.

[0031] In some more specific embodiments, four through holes 52 are evenly formed at the head of the core rod 5 along the circumferential direction.

[0032] In some embodiments, the coaxial cables are evenly distributed around the periphery of the heat conducting rod 3 .

[0033] In some embodiments, the outer wall of the heat conducting rod 3 is provided with one or a combination of a cooling layer 7 and an anti-adsorption layer 8. The thickness of the cooling layer 7 and the anti-adsorption layer 8 are 1-3 mm respectively.

[0034] In some more specific embodiments, the outer wall of the thermally conductive rod 3 is sequentially provided with a cooling layer 7 and an anti-adsorption layer 8 from the inside to the outside. The cooling layer 7 is provided to improve the heat dissipation capacity of the thermally conductive rod 3, and the anti-adsorption layer 8 is provided to prevent dust from accumulating on the outside of the thermally conductive rod 3 and affecting its heat dissipation.

[0036] like Figure 1-9As shown, a high-power connector with a heat dissipation structure includes a cluster connector body 1, a coaxial cable 2 and a heat dissipation structure. The cluster connector body 1 and the coaxial cable 2 can be conventional products. There are four coaxial cables 2 and they are all arranged on the cluster connector body 1. The heat dissipation structure includes at least one heat-conducting rod 3 for transferring heat. The heat-conducting rod 3 is made of copper material with a high thermal conductivity coefficient. One end of the heat-conducting rod 3, i.e., the head, is arranged on the cluster connector body 1. Four coaxial cables are evenly distributed on the periphery of the heat-conducting rod 3. The other end of the heat-conducting rod 3 is suspended and six heat-dissipating fins 4 are arranged on the end to increase the contact area with the air and facilitate heat dissipation. The heat generated by the connector is transferred to the heat-dissipating fins 4 through the heat-conducting rod 3, so as to realize heat transfer and heat dissipation, avoid heat accumulation affecting the normal use of the device, and help to improve the service life of the device.

[0037] In order to improve the heat dissipation capacity, a gap is provided inside the heat conducting rod 3 for the flow of coolant. After the coolant is filled inside, all assembly gaps are welded and sealed.

[0038] In this embodiment, the core rod 5 is inserted into the heat-conducting rod 3, and a gap is left between the inner wall of the heat-conducting rod 3 and the outer wall of the core rod 5 therein, and the gap is filled with coolant. A limiting step 51 is provided at the head of the core rod 5 to limit the position, so that the core rod 5 is not completely embedded in the heat-conducting rod 3, that is, the head of the core rod 5 is partially exposed outside the heat-conducting rod 3. Four through holes 52 are evenly opened in the circumferential direction at the head of the core rod 5, and the core rod 5 is designed to be an internal hollow structure from the position of the through holes 52 to the tail. Eight protrusions 53 are arranged at intervals along the circumferential direction on the outer side of the tail of the core rod 5 to support the inside of the heat-conducting rod 3 and prevent tilting. The opening on the inner side of the tail of the core rod 5 is in a trumpet shape to facilitate the flow of coolant to the center, and the inside of the core rod 5 is connected to the gap. An adaptive flow guide 6 is arranged inside the end of the suspended end of the heat conducting rod 3. The heat conducting rod 3, the core rod 5 and the flow guide 6 are coaxially arranged and have adapted sizes. The core rod 5 has the smallest size. The heat conducting rod 3 and the flow guide 6 have the same size and are larger than the core rod 5. The flow guide 6 has a convex center and is arc-shaped all around, which is used to guide the flow direction of the coolant.

[0039] The outer wall of the heat-conducting rod 3 is sequentially provided with a cooling layer 7 and an anti-adsorption layer 8 from the inside to the outside. The thickness of the cooling layer 7 and the anti-adsorption layer 8 are 1 mm respectively. The cooling layer 7 is provided to improve the heat dissipation capacity of the heat-conducting rod 3, and the anti-adsorption layer 8 is provided to prevent dust from accumulating on the outside of the heat-conducting rod 3 and affecting its heat dissipation.

[0040] The cooling layer 7 is a super hygroscopic polymer film layer, and the anti-absorption layer 8 is a polytetrafluoroethylene film layer. The cooling layer 7 and the anti-absorption layer 8 are existing products.

[0041] When the core rod 5 is inserted into the heat-conducting rod 3, it is limited by the limiting step 51, the through hole 52 is located in the gap surrounded by the heat-conducting rod 3 and the core rod 5, the inside of the core rod 5 is connected with the gap, the protrusion 53 contacts the inner wall of the heat-conducting rod 3, and the coolant can circulate in the gap, the core rod 5, and the guide member 6.

[0042] During use, when the cluster connector body 1 is heated, the coolant expands due to the heat and flows to the suspended end of the heat conducting rod 3. After cooling at the heat dissipation fins 4, it flows back from the suspended end, enters the core rod 5 from the bell mouth at the tail of the core rod 5, flows to the head of the heat conducting rod 3, and then flows out from the through hole 52 at the head of the core rod 5, forming a circular flow. Fig. 9 The red arrow in the middle indicates the flow direction of the coolant.
