Description

Preterminated wire harness

Technical Field

The utility model relates to a pre-terminated wire harness, which is a bunched pre-terminated cable.

Background

The pre-termination, as the name implies, is to terminate components such as modules, plugs and the like before leaving the factory, and provides a choice of easy installation and low cost compared with field termination, thereby ensuring that the pre-terminated product can be inserted and used after reaching the field. And the pre-terminated products are subjected to performance test before leaving the factory, so that field test is omitted, the field test period is greatly shortened, field rapid construction is facilitated, and the construction period is shortened.

The pretermination wiring harness is one of pretermination products and comprises a plurality of (such as 6) data cables (or other optical cables and the like), and components such as pretermination modules and plugs at two ends of the data cables. In order to bundle a plurality of data cables, a plurality of data cables are usually wrapped with a high-strength nylon woven mesh pipe at present. However, the pre-terminated wire harness of this construction suffers from the following problems during manufacture and use: (1) during production, a single data cable can easily penetrate into the nylon woven mesh pipe, but the nylon woven mesh pipe is soft, so that a plurality of data cables bring great troubles to the penetrating process, the production is time-consuming and labor-consuming, and the efficiency is low. (2) The nylon woven mesh pipe is loose, the restraint on a plurality of data cables is limited, the positions of the plurality of data cables in the nylon woven mesh pipe are difficult to fix and easy to be shifted, and the data cables are often scattered and have no seal. (3) The information of the wire harness can not be marked outside the nylon woven mesh pipe. (4) The nylon woven net pipe has rough surface, which is not beneficial to threading and wiring.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem of providing a pre-terminated wire harness which is convenient to produce and use and improves the bundling quality.

In order to solve the technical problem, the pretermination wiring harness comprises a plurality of cables, components are preterminated at one end or two ends of each cable, the cables are uniformly distributed on the outer sides of the round supporting bars, and bundling layers are extruded outside the cables.

Specifically, the component is a connector, and the connector is an RJ45 module or an RJ45 plug.

Preferably, the plurality of cables are twisted together outside the support strip.

Preferably, the supporting bars are round hollow plastic pipes, so that the plurality of cables are compact in structure and elastic, and the pre-terminated wire harness can be not only elastic but also restored to the original shape after being extruded or bent.

For the convenience of production, the material of the bundling layer is common polyvinyl chloride, polyolefin or fluorine-containing polymer and the like.

The cable bundled by the utility model is an electric cable or an optical cable, and the electric cable is a data cable used in a machine room.

The utility model has the beneficial effects that:

1. the wire harness is integrally formed, and the structure is compact;

2. the center of the wire harness is provided with the plastic supporting bar, and the outer layer of the wire harness is provided with the bundling layer, so that the position is easy to fix and not easy to string;

3. the cluster is processed and formed by equipment (a polymer material extrudes a cluster layer), so that the processing efficiency is high, and the cost is low;

4. the diameter of the plastic support bar is adjustable, and the number of the cores of the cable can be expanded by changing the diameter of the plastic support bar;

5. in engineering construction, the bundling layer of the utility model has smooth surface, is easy to wire and pipe, is convenient for construction, improves the construction efficiency and further reduces the construction period;

6. the utility model has a bundling layer (similar to a cable outer sheath), and product information is easy to print on the surface of the bundling layer.

Detailed Description

As shown in fig. 1-6, the preterminated wire harness includes a plurality of cables 2 (six cables 2 as shown in fig. 6), the cables 2 being electrical or optical cables. As shown in fig. 6, the cable is a data communication cable. The cable 2 can be selected from environment-friendly enhanced type, low-smoke halogen-free type and flame retardant type, and the cable 2 can be selected from super-five type non-shielding, super-five type shielding, six type non-shielding, six type shielding and super-six type shielding.

One or both ends of the cable 2 are terminated with components, in particular connectors, such as RJ45 modules 4 or RJ45 plugs 5. Such as RJ45 module 4-RJ45 plug 5 (i.e., preterminated on one end and preterminated on the other end, the same below) preterminated wiring harness (as shown in fig. 1), RJ45 module 4-null preterminated wiring harness (as shown in fig. 2), RJ45 plug 5-RJ45 plug 5-preterminated wiring harness (as shown in fig. 3), RJ45 module 4-RJ45 module 4-preterminated wiring harness (as shown in fig. 4), and RJ45 plug 5-null preterminated wiring harness (as shown in fig. 5).

As shown in fig. 6, the plurality of cables 2 are uniformly distributed outside the circular support bar 3, and specifically, the plurality of cables 2 are twisted together outside the support bar 3.

Support bar 3 is circular hollow plastic pipe, when extruding the layer of gathering a bundle 1, can suitably extrude hollow plastic pipe, like this, compact structure between a plurality of cables 1 has elasticity, not only can produce elasticity after extrusion or bending the pre-terminated pencil, can make the pre-terminated pencil reconversion moreover. Moreover, the diameter of the support strip 3 is adjustable, and the number of cable cores can be expanded by changing the diameter of the plastic support strip 3.

The bundling layer 1 is extruded outside the plurality of cables, and the material of the bundling layer 1 is common plastic material, such as polyvinyl chloride, polyolefin or fluoropolymer. The surface of the bundling layer 1 can be printed with product information.

During production, bundling is carried out by equipment (the high polymer material extrudes the bundling layer 1), the processing efficiency is high, and the cost is low. When the bundling layer is used, the surface of the bundling layer 1 is smooth, wiring and pipe penetration are easy, construction is convenient, construction efficiency is improved, and the construction period is shortened.
