Technical Field
[0001] The utility model relates to the technical field of electrical connection terminals, in particular to an anti-short circuit terminal. Background Art
[0002] Terminals with metal springs inside are common electrical connection components in communications. Terminals in the prior art often cause short circuits between springs due to external water ingress or accumulation, and cannot be effectively waterproofed both when not in use (for example, during storage or transportation) and when in use to avoid internal short circuits. Utility Model Content
[0003] The technical problem to be solved by the utility model is to overcome the defect in the prior art that the terminal cannot be waterproof both when in use and when not in use to effectively avoid internal short circuit, and to provide an anti-short circuit terminal.
[0004] The utility model solves the above technical problems through the following technical solutions:
[0005] A short-circuit proof terminal, comprising an outer cover and a plurality of springs, wherein the outer cover comprises a plurality of jacks arranged at intervals, each of the springs is arranged in a corresponding jack, and the springs are used as electrical connection components for communication.
[0006] The anti-short circuit terminal also includes a waterproof component, which covers the top surface of the outer cover. The outer cover also includes at least one mounting hole, and the waterproof component includes a first protrusion inserted into the mounting hole; a hydrophobic groove is provided on the top surface of the outer cover.
[0007] In this scheme, by covering the top surface of the outer cover with a waterproof part, the terminal effectively blocks external water from entering the jack in the outer cover when it is not in use, forming the first waterproofing, avoiding large-scale water accumulation inside. By setting a hydrophobic groove on the top surface of the outer cover, when the terminal is in use, after removing the waterproof part, the hydrophobic groove can be used to actively collect and drain the water around it, forming the second waterproofing, avoiding the accumulated water from the top surface of the outer cover into the jack, causing the reeds to form a waterway and cause a short circuit. By setting the reeds in the jacks arranged at intervals, a third waterproofing is formed to isolate the water in different jacks, avoiding the short circuit between the reeds due to water collusion. By inserting the first protrusion into the mounting hole, on the one hand, it can prevent external water from entering the mounting hole and affecting the installation, and on the other hand, it also makes it difficult for the waterproof part to fall off and lose its waterproofing effect. The anti-short-circuit terminal can be waterproof both when in use and when not in use through the above three waterproofing measures, effectively avoiding internal short circuits.
[0008] Preferably, the waterproof member further comprises a plurality of second protrusions inserted into the insertion holes;
[0009] The second protrusion and the insertion hole are in interference fit, and / or the first protrusion and the mounting hole are in interference fit.
[0010] In the present embodiment, the anti-short-circuit terminal adopts an interference fit between the second protrusion and the socket, and / or the first protrusion and the mounting hole, so that there is greater resistance when the first protrusion and / or the second protrusion are pulled out, thereby effectively preventing the waterproof part from falling off and losing the waterproof effect.
[0011] Preferably, an outer diameter of the first protrusion gradually decreases along an extending direction of the first protrusion into the mounting hole, and an initial end of the first protrusion in the extending direction is interference fit with the mounting hole.
[0012] In the present solution, the outer diameter of the first protrusion gradually decreases along the direction in which it extends into the mounting hole, so that the first protrusion forms a cone; and an initial end of the first protrusion in the direction of extension is interference fit with the mounting hole, that is, an interference fit is formed only at the initial end of the cone, so that the first protrusion has an anti-loosening effect and can be plugged in and out without too much effort when it needs to be pulled out, and the operation is easier.
[0013] Preferably, the end of the first protrusion extending into the mounting hole is provided with a buckle protruding radially outward along the mounting hole, and the mounting hole is provided with a step matching the buckle, and the buckle is used to be clamped on the step when the first protrusion extends into the mounting hole.
[0014] In this solution, through the cooperation of the buckle and the step provided above, when the first protrusion is inserted into the mounting hole, it is stably clamped in the mounting hole, thereby improving the reliability of loosening.
[0015] A short-circuit-proof terminal, comprising an outer cover and a plurality of springs, wherein the outer cover comprises a plurality of jacks arranged at intervals, each of the springs is arranged in a corresponding jack, and the springs are used for electrical connection.
[0016] The anti-short circuit terminal also includes a waterproof component, which is covered on the top surface of the outer cover and includes a plurality of second protrusions inserted into the insertion holes; a hydrophobic groove is provided on the top surface of the outer cover.
[0017] In this solution, by covering the top surface of the outer cover with a waterproof member, the terminal effectively blocks external water from entering the jack in the outer cover when it is not in use, forming the first waterproofing, avoiding large-scale water accumulation inside. By setting a hydrophobic groove on the top surface of the outer cover, when the terminal is in use, after removing the waterproof member, the hydrophobic groove can be used to actively collect and drain the water around it, forming the second waterproofing, avoiding the accumulated water from the top surface of the outer cover into the jack, causing the reeds to form a waterway and cause a short circuit. By setting the reeds in the jacks arranged at intervals, a third waterproofing is formed to isolate the water in different jacks, avoiding the short circuit between the reeds due to water collusion. By inserting the second protrusion into the jack, on the one hand, the jack can be prevented from directly entering the water, and on the other hand, the waterproof member is not easy to fall off and lose the waterproofing effect. In the absence of the first protrusion, the solution can also achieve the anti-falling effect through the second protrusion. The anti-short-circuit terminal can be waterproof both when in use and when not in use through the above three waterproofing measures, effectively avoiding internal short circuits.
[0018] Preferably, the hydrophobic groove is arranged between two adjacent insertion holes, and / or the height of the hydrophobic groove gradually decreases, and / or the height of the top surface of the outer cover gradually decreases.
[0019] Compared with setting the hydrophobic groove at other positions, in this solution, the hydrophobic groove is set between two adjacent sockets. The water collected by the hydrophobic groove is directly the water around the socket, which shortens the path through which the water around the socket is collected and flows, and more effectively prevents water accumulation. The height of the hydrophobic groove is gradually reduced, so that the hydrophobic groove has an inclined drop, which is conducive to the smooth discharge of accumulated water. The top surface height of the outer cover is gradually reduced, and the entire top surface forms a slope structure. Whether the water in the hydrophobic groove or the water outside the hydrophobic groove can be discharged smoothly along the slope.
[0020] Preferably, the outer cover is provided with a chamfer at the top of the insertion hole, and the aperture of the insertion hole at the chamfer gradually increases from the inside of the insertion hole to the top of the insertion hole.
[0021] In this solution, the chamfer set as above is adopted, and the chamfer forms an inverted cone-shaped cavity structure, so that even if there is water around the top of the socket, it will flow into the socket through the chamfer, and will not form a small water channel between the sockets, thereby causing a short circuit.
[0022] Preferably, the anti-short-circuit terminal is provided with a bottom plate at the bottom of the outer cover, the bottom plate covers the bottom surface of the jack, and the reed passes through the bottom plate so that part of the reed is exposed on the lower surface of the bottom plate.
[0023] In this solution, the bottom plate covers the bottom surface of the jack, and the bottom of the outer cover further blocks external water from entering the jack to prevent internal short circuit. At the same time, when the terminal is not in use, the waterproof part on the top of the jack and the bottom plate at the bottom isolate the jack into an independent inner cavity to prevent water from flowing between the inner cavities of the jack and causing a short circuit.
[0024] Preferably, a gap between the bottom plate and the outer cover is filled with a sealing material, and / or a gap between the bottom plate and the reed is filled with a sealing material.
[0025] In this solution, by setting the above-mentioned filling sealing material, the existence of a tiny water path in the gap between the bottom plate and the outer cover and / or the reed is avoided, so that the inner cavity of the jack is formed into a completely closed inner cavity, thereby improving the reliability of waterproofing and short-circuit prevention.
[0026] Preferably, the waterproof component is made of elastic material.
[0027] In this solution, the waterproof part is made of elastic material, which can more effectively seal the top surface of the outer cover and improve the waterproof insulation effect of the top surface.
[0028] The positive and progressive effect of the utility model is that the short-circuit-proof terminal is waterproof both when in use and when not in use through three waterproof measures, effectively avoiding internal short circuits. By inserting the second protrusion into the plug hole and / or the first protrusion into the mounting hole, external water is prevented from entering the plug hole and / or the mounting hole, and the waterproof part is not easy to fall off and lose the waterproof effect.

[0054] A preferred embodiment is given below, and the present invention is described more clearly and completely in conjunction with the accompanying drawings.
[0055] like Figure 1-7 As shown, this embodiment provides an anti-short circuit terminal 1, which is used in the communication field as an electrical connection component. Figure 1 As shown, the anti-short-circuit terminal 1 includes an outer cover 2 and a plurality of springs 3. The outer cover 2 is specifically an injection-molded plastic part. The outer cover 2 includes a plurality of spaced-apart jacks 4, and each spring 3 is disposed in a corresponding jack 4. The jack 4 is specifically a through slot, and the spring 3 is specifically a metal sheet. As an electrical connection component, the metal spring 3 is disposed in the jack 4. When used, the spring 3 of the anti-short-circuit terminal 1 (for example, as a male plug terminal) exposed on the bottom surface of the outer cover 2 is inserted into another connector (for example, a female plug terminal) and contacts with a metal part in the other connector to establish an electrical connection.
[0056] The anti-short circuit terminal 1 also includes a waterproof member 5, which is covered on the top surface of the outer cover 2. The waterproof member 5 includes two mounting holes 8, and the waterproof member 5 also includes a first protrusion 9 inserted into the mounting hole 8; a hydrophobic groove 7 is provided on the top surface of the outer cover 2. Specifically, the waterproof member 5 is an elastic rubber sheet (for example, a silicone rubber sheet). By utilizing its elastic properties, its protrusion can be more effectively inserted into the hole structure in the outer cover 2, more effectively seal the top surface of the outer cover 2, and improve the waterproof insulation effect of the top surface. Such a waterproof member 5 is also called a waterproof plug. The mounting hole 8 is a countersunk hole, which is provided at both ends of the outer cover 2, and all the jacks 4 are between the two mounting holes 8. When installing the terminal, fasteners such as bolts 16 are connected to other connectors through this countersunk hole. Of course, in other embodiments, the waterproof member 5 can also be made of other materials that can achieve a waterproof effect.
[0057] The anti-short-circuit terminal 1 is covered on the top surface of the outer cover 2 by the waterproof member 5, so that when the terminal is not in use, it effectively blocks external water from entering the plug hole 4 in the outer cover 2, forming the first waterproofing to avoid large-scale water accumulation inside, and the first waterproofing measure can prevent a large amount of water from entering the plug hole 4. By arranging a hydrophobic groove 7 on the top surface of the outer cover 2, when the terminal is in use, after removing the waterproof member 5, the hydrophobic groove 7 can be used to actively collect and drain the water around it, forming a second waterproofing to prevent the accumulated water from flowing into the plug hole 4 from the top surface of the outer cover 2, resulting in a waterway between different reeds 3 and causing a short circuit; the second waterproofing can actively collect the surface water, drain and discharge it when a small amount of water still accumulates on the top surface of the terminal 1 after the first waterproofing measure. By arranging the reed 3 in the jacks 4 arranged at intervals, a third waterproofing is formed to isolate the water in different jacks 4, and to prevent the reeds 3 from short-circuiting due to water collusion. Usually, after the first and second waterproofing measures, there is little water on the surface of the terminal 1 and in the jacks 4. Even if there is a small amount of water that is not prevented by the first two measures and accumulates in the jacks 4, the third waterproofing measure completely isolates the accumulated water in different jacks 4 without the possibility of contact, which can effectively ensure that the reeds 3 will not short-circuit due to water collusion. The small amount of accumulated water in the jacks 4 will also be discharged by product tilting, vibration, evaporation, etc., and will not affect the normal electrical connection of the reed 3 in the terminal 1. By inserting the first protrusion 9 into the mounting hole 8, on the one hand, it can prevent external water from entering the mounting hole 8 and affecting the installation, and on the other hand, it also makes it difficult for the waterproof part 5 to fall off and lose its waterproofing effect. The anti-short-circuit terminal 1 can be waterproof both when in use and when not in use through the above three waterproofing measures, effectively avoiding internal short circuits.
[0058] Among them, Figure 3As shown, the waterproof member 5 also includes a plurality of second protrusions 6 inserted into the insertion hole 4. The anti-short-circuit terminal 1 can prevent water from directly entering the insertion hole 4 by inserting the second protrusions 6 into the insertion hole 4, and on the other hand, it also makes it difficult for the waterproof member 5 to fall off and lose the waterproof effect. In other embodiments, if the waterproof member 5 does not have the first protrusion 9, the second protrusion 6 can also achieve the anti-falling effect.
[0059] In this embodiment, the lower surface of the waterproof member 5 has protrusions corresponding to the jack 4 and the mounting hole 8, which can play a better role in preventing the waterproof member 5 from falling off and preventing external water from entering the corresponding holes. In other embodiments, the jack 4 may not have a corresponding protrusion, or the mounting hole 8 may not have a corresponding protrusion, and only one of the protrusion structures can prevent the waterproof member 5 from falling off; or, in some terminal structures, if there is no mounting hole 8, only a protrusion structure corresponding to the jack 4 can be provided to achieve the effect of preventing the waterproof member 5 from falling off. In other embodiments, the number and structure of the mounting holes 8 can also be adjusted accordingly according to the specific structure of the terminal.
[0060] Among them, the first protrusion 9 and the mounting hole 8 are in an interference fit, while the second protrusion 6 and the socket 4 are in a non-interference fit. In this way, when the first protrusion 9 is pulled out, there is a large resistance, which can effectively prevent the waterproof part 5 from falling off and losing the waterproof effect; and the second protrusion 6 and the socket 4 are in a non-interference fit. On the one hand, it reduces the dimensional accuracy requirements of the waterproof part 5 and reduces the manufacturing difficulty. On the other hand, when the waterproof part 5 needs to be peeled off, the second protrusion 6 will also be easier to pull out, and both protrusions (the second protrusion 6 and the first protrusion 9) will not be difficult to pull out, which is convenient for operation.
[0061] In other embodiments, the selection of which pair of protrusions and holes to adopt interference fit can be made according to the effect of covering and peeling the waterproof member 5 from the outer cover 2. For example, the second protrusion 6 and the insertion hole 4, the first protrusion 9 and the mounting hole 8 can all adopt interference fit, which can more reliably ensure that the waterproof member 5 is not easy to fall off. However, such a solution is not as good as the present embodiment in which only the first protrusion 9 and the mounting hole 8 adopt interference fit, which is more convenient to use.
[0062] Among them, Figure 3 As shown, the outer diameter of the first protrusion 9 gradually decreases along the insertion direction A of the first protrusion 9 into the mounting hole 8, and the initial end 10 of the first protrusion 9 in the insertion direction A is interference fit with the mounting hole 8, so that the first protrusion 9 forms a cone, and the initial end 10 in the insertion direction A is interference fit with the mounting hole 8, that is, the interference fit is only formed at the initial end 10 of the cone, so that the first protrusion 9 has an anti-loosening effect, and when it needs to be pulled out, it will not be too laborious and difficult to plug and unplug, and the operation is easier.
[0063] The end of the first protrusion 9 extending into the mounting hole 8 is provided with a buckle 11 protruding outward along the radial direction of the mounting hole 8, and a step 12 cooperating with the buckle 11 is provided in the mounting hole 8. The buckle 11 is used to be clamped on the step 12 when the first protrusion 9 extends into the mounting hole 8. Through the cooperation between the buckle 11 and the step 12, when the first protrusion 9 is inserted into the mounting hole 8, it is stably clamped in the mounting hole 8, thereby improving the reliability of loosening.
[0064] Among them, Figure 4 and Figure 5 As shown, in this embodiment, the hydrophobic groove 7 is arranged between two adjacent sockets 4, the height of the hydrophobic groove 7 is gradually reduced, and the height of the entire top surface of the outer cover 2 is gradually reduced. Compared with setting the hydrophobic groove 7 at other positions, in the embodiment, the hydrophobic groove 7 is arranged between two adjacent sockets 4, and the water collected by the hydrophobic groove 7 is directly the water around the socket 4, shortening the path through which the water around the socket 4 is collected, and more effectively preventing water accumulation. The height of the hydrophobic groove 7 is gradually reduced, so that the hydrophobic groove 7 has an inclined drop, which is conducive to the smooth discharge of accumulated water, and in this embodiment, the height of the entire top surface of the outer cover 2 is gradually reduced, and the entire top surface forms a slope structure, whether the water in the hydrophobic groove 7 or the water outside the hydrophobic groove 7 can be discharged smoothly along the slope. In other embodiments, according to the size and specific structure of the top surface of the outer cover 2, without affecting the hydrophobic effect, only the height of the hydrophobic groove 7 can be gradually reduced, and it is not limited to the requirement that other surface structures on the top are all inclined.
[0065] Among them, Figure 4 As shown, the outer cover 2 is provided with a chamfer 13 at the top of the socket 4, and the aperture of the socket 4 at the chamfer 13 gradually increases from the inside of the socket 4 to the top of the socket 4. With such a chamfer 13 setting, the chamfer 13 forms an inverted cone-shaped cavity structure, so that even if there is water around the top of the socket 4, it will flow into the socket 4 through the chamfer 13, and no small water channel will be formed between the sockets 4, thereby causing a short circuit.
[0066] Among them, Figure 2-7 As shown, the anti-short-circuit terminal 1 is provided with a bottom plate 14 at the bottom of the outer cover 2. The bottom plate 14 is specifically a plastic part, which covers the bottom surface of the jack 4. The reed 3 passes through the bottom plate 14 so that part of the reed 3 is exposed on the lower surface of the bottom plate 14. The bottom plate 14 covers the bottom surface of the jack 4, and further blocks the external water from entering the jack 4 at the bottom of the outer cover 2 to prevent internal short circuit. At the same time, when the terminal is not in use, the waterproof part 5 at the top of the jack 4 and the bottom plate 14 at the bottom isolate the jack 4 into an independent inner cavity to prevent water from flowing between the inner cavities of the jack 4 and causing a short circuit.
[0067] Among them, the gap between the bottom plate 14 and the outer cover 2 is filled with a sealing material 15, and the gap between the bottom plate 14 and the reed 3 is filled with a sealing material 15. In this embodiment, the filled sealing material 15 is specifically glue, and the glue is filled in each gap. In other embodiments, depending on the shape and size of the bottom plate 14, whether there is a gap between it and the outer cover 2 and the reed 3, and the size of the gap may vary due to the specific shape and structure, but in order to prevent external water from entering, glue can be used to fill each gap; and there are many sealing methods, and the sealing material 15 can also use other materials with sealing effects. For example, part of the plastic material of the outer cover 2 and / or the bottom plate 14 can also be melted and creeped through an ultrasonic heating process to fill it into the gap, which can also produce a sealing effect.
[0068] The anti-short-circuit terminal avoids the existence of a tiny water path in the gap between the bottom plate 14 and the outer cover 2 and / or the reed 3 by filling the sealing material, thereby forming the inner cavity of the jack 4 into a completely closed inner cavity, thereby improving the reliability of waterproofing and anti-short-circuit.
[0069] Although the specific implementations of the utility model are described above, those skilled in the art should understand that this is only an example, and the protection scope of the utility model is defined by the attached claims. Those skilled in the art can make various changes or modifications to these implementations without departing from the principle and essence of the utility model, but these changes and modifications fall within the protection scope of the utility model.
