Abstract
Description
Technical Field
[0001] The present application relates to the technical field of connection terminals, and in particular to a heat shrinkable connection terminal. Background Art
[0002] Terminals are an accessory product used to achieve electrical connections. Terminals are classified as connectors in the industry. Existing terminal blocks include heat shrink terminals, hardware terminals, etc.
[0003] The heat shrink terminal includes a heat shrink tube. During use, the heat shrink tube is shrunk by high temperature so that the heat shrink tube can tightly wrap the connection between the two wires after shrinkage, thereby achieving a fixing and waterproofing effect.
[0004] However, since the shrink tube is wrapped around the connection of the wires in a heat shrink manner, the connection between the shrink tube and the wires is poor; the heat shrink tube is prone to move freely on the surface of the wires, causing the connection between the male and female terminals to be exposed to the outside world, posing a safety hazard. Utility Model Content
[0005] In order to improve the stability of the heat shrink tube wrapped around the wire connection, the present application provides a heat shrink connection terminal.
[0006] The present application provides a heat shrinkable connection terminal adopting the following technical solution:
[0007] A heat shrinkable connection terminal comprises a heat shrinkable tube and two half rings, wherein the heat shrinkable tube is sleeved on a wire connection; the two half rings are respectively installed on opposite sides of the inner wall of the heat shrinkable tube, one of the half rings is provided with a plug-in block, and the other half ring is provided with a plug-in slot for plugging in a card block; when the heat shrinkable tube shrinks, the two wire connections are tightly pressed against the plug-in block and the inner wall of the plug-in slot.
[0008] By adopting the above technical solution, when using a heat shrink tube to connect two wires, the heat shrink tube is put on the connection of the two wires, and then the heat shrink tube is heated to shrink it; at this time, the two half rings move toward the side close to each other, so that the plug-in block and the connection of the two wires are abutted and the connection of the two wires enters the plug-in slot, so that the connection of the two wires is clamped between the two half rings, increasing the resistance of the heat shrink tube to move on the two wires, thereby improving the stability between the heat shrink tube and the wires.
[0009] Optionally, a solder layer is provided on the inner wall of the plug-in slot.
[0010] By adopting the above technical solution and setting a solder layer, when the heat shrink tube is heated and shrunk, the solder layer melts and flows into the gap where the two wires are connected, further increasing the stability of the connection between the two wires and improving the signal transmission between the two wires.
[0011] Optionally, one of the half rings is provided with an elastic card block, and the other half ring is provided with an elastic card slot for the elastic card block to be inserted into.
[0012] By adopting the above technical solution, during the heat shrinkage process of the heat shrink tube, the two half rings are close to each other so that the elastic card block and the elastic card slot are plugged into each other, which can reduce the possibility of the two half rings separating from each other and further improve the effect of the two half rings on clamping the connection between the two wires.
[0013] Optionally, an outer diameter of a side of the elastic card block close to the elastic card slot is greater than an outer diameter of a side of the elastic card block away from the elastic card slot.
[0014] By adopting the above technical solution, the elastic card block can be inserted into the elastic card slot to improve the fixing efficiency of the heat shrink tube on the two wires.
[0015] Optionally, both of the two half rings are provided with reinforcement strips, all the reinforcement strips are arranged at intervals around the axis of the heat shrink tube, the two sides of the reinforcement strips are respectively used to abut against the outer wall of the wire and the inner wall of the heat shrink tube, and the reinforcement strips are provided with a rough surface.
[0016] By adopting the above technical solution and setting reinforcing strips, all reinforcing strips are tightly wrapped around the outer wall of the wire during the heating and shrinking process of the heat shrink tube, and the rough surface increases the friction between the reinforcing strips and the wire, further improving the stability of the heat shrink tube wrapping the outer walls of the two wires.
[0017] Optionally, the heat shrink tube is provided with two rubber rings, and the two rubber rings are respectively sleeved on the outer walls of the two wires.
[0018] By adopting the above technical solution and providing a rubber ring, the rubber ring melts during the heating and shrinking process of the heat shrink tube, so that the heat shrink tube and the wire are tightly bonded through the rubber ring, further reducing the free movement of the heat shrink tube on the surface of the wire.
[0019] Optionally, two adjacent reinforcement strips are connected via an elastic strip, and the reinforcement strip is connected to the rubber ring.
[0020] By adopting the above technical solution, by arranging elastic strips and connecting the reinforcing strips with the adhesive ring, it is possible to reduce the situation where the reinforcing strips are close to each other under the elastic force of the elastic strips when the heat shrink tube is heat shrunk, so that the wire can be inserted between the two half rings; and when the heat shrink tube is heated, the adhesive ring melts, so that all the reinforcing strips are pressed against the outer wall of the wire under the elastic force of the elastic strip, and when the adhesive ring solidifies, the reinforcing strips, the heat shrink tube and the wire are integrated, thereby improving the stability of the heat shrink tube installed on the outer wall of the wire.
[0021] Optionally, the outer diameter of the plug-in block is smaller than that of the plug-in slot.
[0022] By adopting the above technical solution, the two wire connections can be easily inserted into the plug-in slot, thereby increasing the contact area between the two half rings and the two wire connections.
[0023] In summary, the present application includes at least one of the following beneficial technical effects:
[0024] 1. By setting two half rings, during the heat shrinking process of the heat shrink tube, the plug-in block abuts against the connection of the two wires and allows them to enter the plug-in slot, so that the connection of the two wires is clamped between the two half rings, increasing the resistance of the heat shrink tube to move on the two wires, thereby improving the stability between the heat shrink tube and the wires;
[0025] 2. By setting an elastic strip and connecting the reinforcing strip with the rubber ring, it is convenient to pass the wire between the two half rings; when the heat shrink tube is heated, the rubber ring melts so that all the reinforcing strips are pressed against the outer wall of the wire under the elastic force of the elastic strip, and after the rubber ring solidifies, the reinforcing strip, the heat shrink tube and the guide are integrated, thereby improving the stability of the heat shrink tube installed on the outer wall of the guide.

DETAILED DESCRIPTION
[0033] The following is combined with Figure 1-6 This application is described in further detail. Example
[0034] Embodiment 1 of the present application discloses a heat shrinkable connection terminal.
[0035] Reference Figure 1 A heat shrinkable connection terminal includes a heat shrinkable tube 1 and two half rings 2. The heat shrinkable tube 1 is sleeved on the connection between two wires 6 to wrap the connection between the wires 6; the two half rings 2 are used to clamp the connection between the wires 6.
[0036] Reference Figure 1 The inner wall of the heat shrink tube 1 is provided with an insulating layer 11, which is made of an insulating material with high resistivity. The insulating material does not conduct electricity under the allowable voltage, which can reduce the possibility of electric shock caused by people touching the heat shrink tube 1 when the wire 6 is in use.
[0037] Reference Figure 2 and Figure 3 The heat shrink tube 1 is provided with two rubber rings 4, which are respectively sleeved on the outer walls of the two wires 6. During the heating and shrinking process of the heat shrink tube 1, the two rubber rings 4 melt, so that the heat shrink tube 1 can be adhered to the outer walls of the two wires 6, thereby increasing the stability of the connection between the heat shrink tube 1 and the wires 6 and reducing the free movement of the heat shrink tube 1 on the two guide outer walls.
[0038] Reference Figure 3 The two half rings 2 are respectively arranged on the two opposite inner walls of the heat shrink tube 1. When the heat shrink tube 1 is inserted into the guide, the two half rings 2 are respectively located on the opposite sides of the connection of the two wires 6. One of the half rings 2 is provided with a plug-in block 3, and the other half ring 2 is provided with a plug-in slot 21 for the plug-in block 3 to be plugged in. The inner diameter of the plug-in slot 21 is larger than the outer diameter of the plug-in block 3.
[0039] A solder layer 22 is provided on the inner wall of the plug slot 21. When the heat shrink tube 1 shrinks so that the connection between the two wires 6 is clamped between the plug block 3 and the inner wall of the plug slot 21, the solder layer 22 melts and causes the connection between the two wires 6 to adhere, thereby maintaining signal transmission when the two wires 6 are in use.
[0040] Reference Figure 4 In this embodiment, a first through hole 31 is provided on one side of the plug-in block 3 close to the plug-in slot 21, and a second through hole 32 is provided on the side wall of the plug-in block 3, and the first through hole 31 and the second through hole 32 are connected; when the solder layer 22 melts, the solder layer 22 can melt and enter the first through hole 31 and the second through hole 32, further integrating the two half rings 2 with the two wires 6, thereby improving the stability of the heat shrink tube 1 installed on the two wires 6.
[0041] Reference Figure 2One of the half rings 2 is provided with an elastic block 23, and the outer diameter of the side of the elastic block 23 close to the half ring 2 is larger than the outer diameter of the side of the elastic block 23 away from the half ring 2; the other half ring 2 is provided with an elastic slot 24 for the elastic block 23 to engage. During the heat shrinking process of the heat shrink tube 1, the elastic block 23 is inserted into the elastic slot 24 by interference fit, which can reduce the movement of the two half rings 2 toward the side away from each other, so as to keep the two half rings 2 clamping the connection of the two wires 6.
[0042] The implementation principle of Example 1 of the present application is:
[0043] When the heat shrink tube 1 is used to connect the two wires 6, the heat shrink tube 1 is placed on the connection between the two wires 6, and then the heat shrink tube 1 is heated to shrink it; at this time, the two half rings 2 move toward the side close to each other, so that the plug-in block 3 and the connection between the two wires 6 are abutted and the connection between the two wires 6 is inserted into the plug-in slot 21, so that the connection between the two wires 6 is clamped between the two half rings 2, increasing the resistance of the heat shrink tube 1 to move on the two wires 6, thereby improving the stability between the heat shrink tube 1 and the wires 6. Example
[0044] Embodiment 2 of the present application discloses a heat shrinkable connection terminal.
[0045] Reference Figure 5 and Figure 6 The difference between Example 2 of the present application and Example 1 is that: the outer walls of the two semi-rings 2 are provided with reinforcement strips 5, all the reinforcement strips 5 are arranged at intervals around the axis of the heat shrink tube 1, and the end of the reinforcement strip 5 away from the semi-ring 2 is connected to the rubber ring 4; an elastic strip 51 is arranged between two adjacent reinforcement strips 5.
[0046] When the heat shrink tube 1 is heated to shrink it, the rubber ring 4 melts under the heating of the hot air. At this time, all the reinforcement strips 5 are tightly wrapped around the outer wall of the guide under the elastic force of the elastic strip 51, and the heat shrink tube 1, the reinforcement strips 5 and the guide are integrated as a whole due to the melting of the rubber ring 4, further improving the stability of the heat shrink tube 1 installed on the outer walls of the two wires 6.
[0047] The outer wall of the reinforcing strip 5 is provided with a rough surface, and the provision of the rough surface can increase the friction between the reinforcing strip 5 and the wire 6, and further improve the stability of the heat shrink tube 1 installed at the guide connection.
[0048] The above are preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
