Description

Technical Field

[0001] The utility model relates to a COM terminal, in particular to a novel COM terminal connector structure. Background Art

[0002] With the rapid development of the market, COM terminals (common terminals) are becoming increasingly widely used, and more and more companies are engaged in COM terminal production and processing. Intense market competition is driving product optimization. For cost control and market responsiveness, continuous product optimization also requires COM terminal structure simplification and increased functionality.

[0003] The biggest problem with the original COM terminal structure was the limited diameter of wires that could be connected to the same COM terminal model. The five outlets could only accommodate a maximum of four different wire diameters. Once the wire diameter exceeded the compatible COM terminal's capacity, a larger COM terminal model would be required. This limited compatibility increased the time required to switch COM terminal models, the variety and quantity of materials required, and increased material management and manufacturing costs for customers. Utility Model Content

[0004] In response to the problems existing in the prior art, the present invention provides a new COM terminal connector structure. By adding a rubber plug and improving the existing structure, the wire diameters compatible with the current COM terminal products can be expanded from N to 2N. Due to the significant increase in compatibility, in addition to reducing the loss of working hours when replacing materials, it can also effectively reduce the types and quantities of COM terminal materials for customers, saving material management costs.

[0005] The technical solution of the utility model is: a novel COM terminal connector structure, comprising a base assembly, a plug assembly, a plurality of plugs and a locking cap;

[0006] The plug assembly includes a rubber plug, a clamping ring, a plug and a plate buckle;

[0007] The clamping ring is made of elastic silicone rubber and is evenly provided with a plurality of axial through holes, each of which can be equipped with a detachable rubber plug;

[0008] The rubber plug is made of elastic silicone rubber, and the axial opening of the rubber plug can pass through the wire.

[0009] Furthermore, a crack is broken along the axial direction on the circumferential surface of the rubber plug to form a rubber plug fracture surface.

[0010] Furthermore, a plurality of cracks connected with the through holes are broken in the axial direction on the circumferential surface of the clamping ring to form a fracture surface of the clamping ring.

[0011] Furthermore, an annular groove is provided on the outer surface of the rubber plug, and an annular protrusion is provided on the inner surface of the through hole corresponding to the annular groove. When the rubber plug is installed in the through hole, the annular groove and the annular protrusion are connected in a matching manner.

[0012] Furthermore, one end of the plug is a cylindrical connecting end, the tail end of the cylindrical connecting end is processed with an external thread, and the head end of the cylindrical connecting end is a clamping ring mounting hole formed by a plurality of rectangular teeth arranged in a ring shape, and the clamping ring can be inserted into the clamping ring mounting hole.

[0013] Furthermore, a plug can be installed in each rubber plug; after the clamping ring with the plug is installed in the clamping ring installation hole, the clamping ring, rubber plug and plug are locked and sealed by the locking cap.

[0014] Furthermore, positioning posts are provided on two opposite sides of the outer surface of the plug; two plate buckle mounting holes are provided on the plate buckle; after the two plate buckle mounting holes are correspondingly inserted into the two positioning posts of the plug, the plug can be rotated around the positioning posts as the axis;

[0015] The plate buckle is provided with two hooks;

[0016] The base assembly includes a base, and ears are provided on two opposite sides of the outer surface of the base. Two hooks can hook the two ears on the base in a one-to-one correspondence to connect and fix the base assembly with the plug assembly.

[0017] Furthermore, an inner sealing ring is provided on the inner side of the base, and an outer sealing ring is provided on the outer side of the base.

[0018] The beneficial effect of this utility model is that the old connector structure has poor compatibility and cannot meet the needs of connecting wires of different diameters. The utility model provides a new COM terminal connector structure that disconnects the hole of the clamping ring and the hole of the plug, facilitating the installation of additional plugs. When the plug is installed, the wire diameter of the connected wire is small. When the wire diameter to be connected is larger, the plug cannot pass through. In this case, the plug is removed, the wire is passed directly through the clamping ring, and the locking cap is installed and tightened, which greatly increases the compatible wire diameter.

[0019] Based on usage needs, this can effectively reduce the number of COM terminal connectors customers need to purchase (due to the wider range of compatible wire diameters, previously two models, one large and one small, were required to meet demand, but now only one model is needed). This reduces the number of materials and the time required to change COM terminal models. This utility model solves the problem of COM terminal connector compatibility with wires.

DETAILED DESCRIPTION

[0042] The present invention will be further described below with reference to the accompanying drawings.

[0043] like Figure 1-19 As shown, a novel COM terminal connector structure includes a base assembly 13, a plug assembly 12, multiple plugs 8 and a locking cap 9. The plug assembly 12 includes a rubber plug 1, a clamping ring 2, a plug 3 and a plate buckle 4.

[0044] like Figure 2 、 3 As shown, the clamping ring 2 is made of elastic silicone rubber and has five axial through holes 23 evenly arranged on the clamping ring 2. A detachable rubber plug 1 can be installed in each through hole 23. The rubber plug 1 is made of elastic silicone rubber and the axial opening of the rubber plug 1 can pass the wire.

[0045] like Figure 19 As shown, a crack is broken in the axial direction on the circumferential surface of the rubber plug 1 to form a rubber plug fracture surface 19. A plurality of cracks are broken in the axial direction on the circumferential surface of the clamping ring 2 to connect with the through hole 23 to form a clamping ring fracture surface 18. This facilitates the installation of additional rubber plugs. Preferably, an annular groove is provided on the outer surface of the rubber plug 1, and an annular protrusion is provided on the inner surface of the through hole 23 at a position corresponding to the annular groove. When the rubber plug 1 is installed in the through hole 23, the annular groove and the annular protrusion are matched and connected.

[0046] like Figure 4 、 5As shown, one end of the plug 3 is a cylindrical connecting end, the tail end of the cylindrical connecting end is processed with an external thread 20, and the head end of the cylindrical connecting end is a clamping ring mounting hole formed by a plurality of rectangular teeth 17 arranged in a ring shape, and the clamping ring 2 can be inserted into the clamping ring mounting hole.

[0047] like Figure 16 、 17 As shown, a plug 8 can be installed in each rubber plug 1. After the clamping ring 2 with the plug 8 is installed in the clamping ring installation hole, the clamping ring, rubber plug and plug are locked and sealed by the locking cap 9.

[0048] like Figure 6 、 7 As shown, positioning posts 10 are provided on two opposite sides of the outer surface of the plug 3. Two plate buckle mounting holes 11 are provided on the plate buckle 4. After the two plate buckle mounting holes 11 are correspondingly inserted into the two positioning posts 10 of the plug 3, they can rotate around the positioning posts 10 as the axis. Two hooks 14 are provided on the plate buckle 4. The base assembly 13 includes a base 6, and ears 15 are provided on two opposite sides of the outer surface of the base 6. The two hooks 14 can hook the two ears 15 on the base 6 one by one to connect and fix the base assembly 13 to the plug assembly 12.

[0049] like Figure 8 、 9 As shown, Figure 13 、 14 As shown, an inner sealing ring 5 is provided in the inner groove of the base 6 , and an outer sealing ring 7 is provided on the outer side of the base 6 .

[0050] Function implementation process and purpose:

[0051] like Figure 20 As shown, when the first wire with a diameter of No. 1 to No. 4 needs to be passed through the cavity, unplug the plug inside the rubber plug, pass the wire through, and then tighten the locking cap. As the locking cap is tightened, the clamping ring and the rubber plug will fit the wire more and more tightly, forming a sealed state between the inside and outside of the cavity, and external water and dust cannot enter, thereby achieving the purpose of waterproof and dustproof.

[0052] like Figure 21 As shown, when the diameter of the wire to be passed through the cavity is a second wire with a diameter of 5 to 8, remove the plug and rubber stopper, pass the wire through, and then tighten the locking cap. The clamping ring and wire fit more and more tightly, preventing external water and dust from entering, achieving the purpose of waterproof and dustproof.

[0053] The old connector structure had poor compatibility and could not accommodate wires of varying diameters. The new structure disconnects the hole in the clamping ring from the plug hole, facilitating the insertion of additional plugs. With the plug in place, the wire being connected is smaller in diameter. When the wire to be connected is larger in diameter, the plug cannot pass through. In this case, the plug is removed, allowing the wire to pass directly through the clamping ring. By installing the locking cap and tightening it, the compatible wire diameter can be significantly increased.

[0054] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
