Technical Field

[0001] This application relates to the technical field of insulating intermediate terminals, and specifically to an anti-detachment insulating intermediate terminal. Background Art

[0002] Copper tube terminal, also known as intermediate bare terminal and copper tube intermediate terminal, is a fitting product used to achieve electrical connection. Moreover, the intermediate bare terminal is an essential electronic component for connecting circuits in industrial equipment and vehicles such as automobiles. The intermediate bare terminal is produced to facilitate the connection of two wires, and the insulating intermediate terminal is formed by sleeving an insulating sleeve on the intermediate bare terminal.

[0003] Currently, existing insulating intermediate terminals and insulating sleeves are generally connected by interference fit. The connection stability between the insulating sleeve and the intermediate terminal will be reduced due to the influence of thermal expansion and contraction, mechanical vibration, etc., resulting in the loosening of the insulating sleeve and then detachment. Utility Model Content

[0004] Aiming at the deficiencies of the prior art, this application provides an anti-detachment insulating intermediate terminal, which has the advantages of being able to increase the connection stability between the insulating sleeve and the intermediate terminal and avoiding the easy loosening and detachment of the insulating sleeve. It solves the problem that existing insulating intermediate terminals and insulating sleeves are generally connected by interference fit, and the connection stability between the insulating sleeve and the intermediate terminal will be reduced due to the influence of thermal expansion and contraction, mechanical vibration, etc., resulting in the loosening of the insulating sleeve and then detachment.

[0005] To achieve the above object, this application provides the following technical solution: An anti-detachment insulating intermediate terminal includes an intermediate bare terminal. An installation tube is slidably sleeved on the outer circumferential surface of the intermediate bare terminal. An insulating sleeve is fixedly sleeved on the outer circumferential surface of the installation tube. Two chutes are opened inside the intermediate bare terminal. The intermediate bare terminal is slidably connected with two sliding plates through the chutes. On one side of each sliding plate close to the insulating sleeve, a plurality of equally spaced positioning rods are fixedly connected.

[0006] Through the above solution, since existing insulating intermediate terminals and insulating sleeves are generally connected by interference fit, the connection stability between the insulating sleeve and the intermediate terminal will be reduced due to the influence of thermal expansion and contraction, mechanical vibration, etc., resulting in the loosening of the insulating sleeve and then detachment. By providing a plurality of equally spaced positioning rods on the sliding plates and a plurality of corresponding positioning holes on the installation tube, the insulating sleeve and the intermediate bare terminal can be stably connected, avoiding the easy loosening and detachment of the insulating sleeve due to the influence of thermal expansion and contraction, mechanical vibration, etc., and improving the connection stability between the insulating sleeve and the intermediate bare terminal.

[0007] Further, both ends of the insulating sleeve are provided with installation parts, and the inner diameter of the installation part is larger than the inner diameter of the insulating sleeve.

[0008] Through the above solution, it is convenient for the wire to be installed and for the connection part to be sealed.

[0009] Furthermore, equidistantly arranged positioning holes are formed inside the installation pipe, and the outer circumferential surfaces of the positioning rods are respectively slidably inserted into the installation pipe through the positioning holes.

[0010] Through the above solution, the installation pipe is positioned by the positioning rods and the positioning holes, preventing the installation pipe and the insulating sleeve from easily falling off the intermediate bare terminal, and increasing the connection stability between the insulating sleeve and the intermediate bare terminal.

[0011] Furthermore, side plates are fixedly connected to both sides of each sliding plate, and the sides of the side plates close to the intermediate bare terminal are slidably connected to the intermediate bare terminal.

[0012] Through the above solution, the side plates can increase the stability of the sliding plate, and at the same time facilitate the manipulation of the sliding plate through the side plates, providing convenience for the staff.

[0013] Furthermore, two bolts are respectively slidably inserted into each side plate, eight first threaded holes are formed inside the intermediate bare terminal, and the outer circumferential surfaces of the bolts are respectively threadedly connected to the intermediate bare terminal through the first threaded holes.

[0014] Through the above solution, the side plates are positioned by the bolts and the first threaded holes, and then the sliding plate and the positioning rods are positioned, ensuring that the positioning rods are always inserted into the positioning holes to complete the positioning operation of the installation pipe and the insulating sleeve.

[0015] Furthermore, eight second threaded holes are formed inside the intermediate bare terminal, and the positions of the second threaded holes correspond to the positions of the bolts respectively.

[0016] Through the above solution, the sliding plate can be fixed to the bottom of the sliding groove by the bolts and the second threaded holes, further preventing the positioning rods from sliding easily and affecting the installation of the installation pipe.

[0017] Furthermore, four equidistantly arranged mounting plates are fixedly connected to the outer circumferential surface of the intermediate bare terminal, and the outer surfaces of each mounting plate are slidably connected to the installation pipe through the empty grooves formed inside the installation pipe.

[0018] Through the above solution, the mounting plates can assist in the installation of the installation pipe, ensuring that the positions of the positioning rods and the positioning holes can correspond, facilitating the positioning of the installation pipe and the insulating sleeve, and providing convenience for the staff.

[0019] Furthermore, the installation pipe is made of hard metal material, and the insulating sleeve is made of PE material.

[0020] Through the above solution, the installation pipe made of hard metal material can avoid being affected by thermal expansion and contraction, mechanical vibration, etc., thereby increasing the stability of the connection between the insulating sleeve and the intermediate bare terminal.

[0021] Compared with the prior art, the technical solution of the present application has the following beneficial effects:

[0032] Please refer to Figure 1 , Figure 2 and Figure 4 , Both ends of the insulating sleeve 3 are provided with installation parts 4. The inner diameter of the installation parts 4 is larger than the inner diameter of the insulating sleeve 3, which is convenient for installing the wire and sealing the butt joint.

[0033] Please refer to Figure 2 and Figure 3 , A plurality of positioning holes 8 arranged at equal intervals are opened inside the installation tube 2. The outer circumferential surfaces of the positioning rods 7 are respectively slidably inserted into the installation tube 2 through the positioning holes 8. The installation tube 2 is positioned through the positioning rods 7 and the positioning holes 8, preventing the installation tube 2 and the insulating sleeve 3 from easily falling off the intermediate bare terminal 1 and increasing the connection stability between the insulating sleeve 3 and the intermediate bare terminal 1.

[0034] Please refer to Figure 2 , Figure 3 and Figure 4 , On both sides of each sliding plate 6, a side plate 9 is fixedly connected. One side of the side plate 9 close to the intermediate bare terminal 1 is slidably connected with the intermediate bare terminal 1. The side plate 9 can increase the stability of the sliding plate 6 and is also convenient for controlling the sliding plate 6 through the side plate 9, providing convenience for the staff.

[0035] Please refer to Figure 2 , Figure 3 and Figure 5 , Two bolts 10 are respectively slidably inserted into each side plate 9. Eight first threaded holes 11 are opened inside the intermediate bare terminal 1. The outer circumferential surfaces of the bolts 10 are respectively threadedly connected with the intermediate bare terminal 1 through the first threaded holes 11. The side plate 9 is positioned through the bolts 10 and the first threaded holes 11, and then the sliding plate 6 and the positioning rod 7 are positioned, so that the positioning rod 7 is always inserted into the positioning hole 8 to complete the positioning operation of the installation tube 2 and the insulating sleeve 3.

[0036] Please refer to Figure 2 , Figure 3 and Figure 5 , Eight second threaded holes 12 are opened inside the intermediate bare terminal 1. The positions of the second threaded holes 12 correspond to the positions of the bolts 10 respectively. The sliding plate 6 can be fixed at the bottom of the sliding groove 5 through the bolts 10 and the second threaded holes 12, thereby preventing the positioning rod 7 from easily sliding and affecting the installation of the installation tube 2.

[0037] Please refer to Figure 2 、 Figure 3 and Figure 4 , on the outer circumferential surface of the intermediate bare terminal 1, four equally spaced mounting plates 13 are fixedly connected. The outer surface of each mounting plate 13 is slidably connected to the mounting tube 2 through the empty slots provided inside the mounting tube 2. The mounting plates 13 can assist in the installation of the mounting tube 2, enabling the positions of the positioning rods 7 and the positioning holes 8 to correspond, facilitating the positioning of the mounting tube 2 and the insulating sleeve 3, and providing convenience for the staff.

The hard metal mounting tube 2 can avoid being affected by thermal expansion and contraction, mechanical vibration, etc., thereby increasing the stability of the connection between the insulating sleeve 3 and the intermediate bare terminal 1.

[0039] In an anti-dropping insulating intermediate terminal in this embodiment, by arranging a plurality of equally spaced positioning rods 7 on the sliding plate 6 and a plurality of corresponding positioning holes 8 on the mounting tube 2, the insulating sleeve 3 and the intermediate bare terminal 1 can be stably connected, achieving the effect of preventing the insulating sleeve 3 from being easily loosened and dropped due to thermal expansion and contraction, mechanical vibration, etc., and improving the stability of the connection between the insulating sleeve 3 and the intermediate bare terminal 1, and solving the problem that when the intermediate bare terminal 1 and the insulating sleeve 3 are connected by an interference fit, they are affected by thermal expansion and contraction, mechanical vibration, etc., resulting in the insulating sleeve 3 being easily loosened and dropped.

[0040] It should be noted that the intermediate bare terminal 1 is made of copper material.

[0041] The working principle of the above embodiment is as follows:

[0042] A relatively large number of positioning rods 7 and positioning holes 8 can form a firm connection between the intermediate bare terminal 1 and the mounting tube 2. The hard mounting tube 2 can avoid being affected by thermal expansion and contraction, mechanical vibration, etc., thereby preventing the insulating sleeve 3 from being easily loosened and dropped from the intermediate bare terminal 1. When the insulating sleeve 3 needs to be installed on the intermediate bare terminal 1, the insulating sleeve 3 is directly slidably sleeved on the intermediate bare terminal 1 through the mounting tube 2, and then the side plate 9 is toggled to drive the sliding plate 6 to move to both sides, enabling the positioning rods 7 to be inserted into the positioning holes 8. Finally, the bolts 10 are sequentially screwed into the first threaded holes 11 to position the side plate 9 and the sliding plate 6, preventing the positioning rods 7 from moving back, and then the installation of the insulating sleeve 3 is completed.
