Description

Technical Field

[0001] The present application relates to the technical field of sealing rods, and specifically discloses a sealing rod applied to an ABS wiring harness injection molding line body. Background Art

[0002] Injection molding is a method of producing industrial products. Products usually use rubber injection molding and plastic injection molding. Injection molding can also be divided into injection molding and die casting. Injection molding machine (referred to as injection machine or injection molding machine) is the main molding equipment that uses plastic molding molds to make plastic products of various shapes from thermoplastics or thermosetting materials;

[0003] The injection molding connector is a connecting component that connects the injection molding machine and the wire. Usually, the injection molding machine is started after the wire is inserted into the connector. For example, the conventional operation method of the ABS wiring harness injection molding machine is to rivet the sealing plug at the same time as the terminal before injection molding. Since the sealing plug and plug are made of rubber materials that are relatively soft and have poor impact resistance, the rubber material can easily break through the sealing plug and plug during injection molding, causing the sealing plug and plug to deform, resulting in the phenomenon of rubber material leaking into the connector through the gap after the deformation of the sealing plug and plug, resulting in a high scrap rate; and the matching of the docking cannot be met, and the production conditions cannot be met;

[0004] Regarding poor impact resistance: the injection molding machine has strong vibration after starting, and the sealing plug in the connecting hole is very easy to be rushed out;

[0005] Regarding the inability to meet the matching requirements of docking: the wires connected by the connector cannot meet the requirements that all sealing plugs can be inserted. This depends on the aperture and the gap between the wires, and there are size requirements.

[0006] To this end, in order to ensure the smooth progress of the injection molding project and prevent the connector from getting glued in, a sealing rod is designed according to the structure of the connector used in the injection molding, which can replace the sealing plug. In view of this, the inventor proposes a sealing rod for use in ABS wiring harness injection molding line bodies. Utility Model Content

[0007] The utility model aims to solve the problem that the traditional wire harness sealing plug cannot meet the docking matching performance between the wire harness and the connector hole.

[0008] In order to achieve the above object, the utility model provides the following basic solutions:

[0009] A sealing rod using an ABS wire harness injection molding line body comprises a sealing rod body, a through hole for a wire to pass through is provided at the center of the sealing rod body, a first adapter component for adapting to wires of different sizes is provided in the through hole, and a second adapter component for adapting to the device hole of a connector with different inner diameters is provided on the outer periphery of the sealing rod body.

[0010] The principles and effects of this basic solution are:

[0011] 1. Compared with the prior art, the device is made of hard plastic as a whole, which has good impact resistance. They are all separate individual structures. The wire passes through the central hole of the sealing rod and is inserted into the connector hole. Then the sealing rod is inserted into the connector hole along the wire. It has both the anti-sealing effect of the sealing plug and good impact resistance. It protects the internal terminals of the connector very well, reduces the impact on the injection molding machine, greatly improves the molding rate, improves the product quality of the injection molding line, and enables employees to work more efficiently.

[0012] 2. Compared with the existing technology, the size and specifications of this product are highly universal and suitable for different wires and different connector holes.

[0013] 3. Compared with the existing technology, the use of this product can prevent the phenomenon of glue leakage during injection molding, ensure product quality, and thus reduce product costs: reduce the injection molding scrap rate and reduce costs.

[0014] Furthermore, the sealing rod body is made of PE material, which ensures the quality of the entire product and makes the quality more stable.

[0015] Furthermore, the first adapter assembly includes a plurality of first springs fixedly connected to the inner wall of the through hole and a clamping plate arranged on the first springs, and the length of the clamping plate is equal to the depth of the through hole.

[0016] Furthermore, the number of the first springs is at least three, which are respectively arranged at the head section, the middle section and the tail section of the inner wall of the through hole.

[0017] Furthermore, the clamping plate is an inner arc clamping plate, the arc of which is arranged on a side close to the center of the through hole, and when the clamping plate is not subjected to force, the ends of the two clamping plates are in contact, and the first spring is in an uncompressed state.

[0018] Furthermore, a friction surface is provided at the arc surface position of the inner arc clamping plate, and the friction coefficient of the friction surface is higher than the friction coefficient of the outer insulation skin of the wire.

[0019] Furthermore, the second adapter assembly includes a plurality of second springs arranged on the outer periphery of the sealing rod body and a connecting plate arranged at the free ends of the second springs.

[0020] Furthermore, the number of the second springs allows the outer connecting plates to form a ring, with gaps being left between adjacent connecting plates.

[0021] Furthermore, the first spring and the second spring are both compression springs, and the connecting plate is made of the same material as the sealing rod body, which is PE material. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the drawings described below are only some embodiments of the present application. For those skilled in the art, other drawings can be obtained based on these drawings without creative work.

[0024] Figure 2 A front cross-sectional view of a sealing rod applied to an ABS wiring harness injection molding line body proposed in an embodiment of the present application is shown. DETAILED DESCRIPTION

[0025] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0026] The reference numerals in the drawings of the specification include: a sealing rod body 1 , a through hole 2 , a wire 3 , a first spring 4 , a clamping block 5 , a friction surface 6 , a second spring 8 , and a connecting plate 9 .

[0027] Implementation example Figure 1 and Figure 2 As shown:

[0028] A sealing rod used for an ABS wiring harness injection molding line body comprises a sealing rod body 1, a through hole 2 for a wire 3 to pass through is provided at the center of the sealing rod body 1, a first adapter component for adapting to wires 3 of different sizes is provided in the through hole 2, and a second adapter component for adapting to the device hole of a connector with different inner diameters is provided on the outer periphery of the sealing rod body 1.

[0029] Regarding the sealing rod body 1: Compared with the traditional rubber material, the sealing rod body 1 in this case is made of plastic material, specifically PE material, which has enhanced impact resistance and deformation resistance.

[0030] The first adapter assembly includes a plurality of first springs 4 fixedly connected to the inner wall of the through hole 2 and a clamping plate arranged on the first spring 4. The length of the clamping plate is equal to the depth of the through hole 2. The number of the first springs 4 is at least three, which are respectively arranged at the head section, middle section and tail section of the inner wall of the through hole 2. The clamping plate is an inner arc clamping plate. The arc of the clamping plate is arranged on a side close to the center of the through hole 2. When the clamping plate is not subjected to force, the ends of the two clamping plates are in contact, and the first spring 4 is in an uncompressed state.

[0031] A friction surface 6 is provided on the arc surface of the inner arc clamping plate. The friction coefficient of the friction surface 6 is higher than the friction coefficient of the outer insulation skin of the wire 3, thereby enhancing the connection stability between the clamping plate and the wire 3.

[0032] like Figure 2 As shown, the second adapter assembly includes a plurality of second springs 8 arranged on the outer periphery of the sealing rod body 1 and a connecting plate 9 arranged at the free end of the second spring 8. The number of the second springs 8 allows the external connecting plates 9 to form a circular ring, and gaps are left between adjacent connecting plates 9. In addition, the first spring 4 and the second spring 8 are both compression springs, and the connecting plate 9 is made of the same material as the sealing rod body 1, which is PE material.

[0033] Specific implementation process:

[0034] The first step is the preliminary preparation of the wire 3: do not damage the terminal of the wire 3, cut the front end of the wire 3 into a prism shape to facilitate insertion into the through hole 2, and as the wire 3 is inserted into the through hole 2, the terminal passes through the other end of the through hole 2, and then the clamping plate is squeezed to the outer skin of the wire 3, and the first spring 4 is compressed to fix the wire 3. Since the initial setting is that the ends of the two clamping plates are in contact when the clamping plate is not stressed, the clamping plate is basically suitable for most sizes of wires 3 on the market;

[0035] The second step is to connect the terminal of the wire 3 to the connector. At this time, the sealing rod body 1 will be squeezed into the device hole of the connector. In this process, first press the connecting plate 9 to make a part of the connecting plate 9 enter the device hole, and then release it to push the sealing rod body 1 to continue to move into the device hole. At this time, the connecting plate 9 will be squeezed and the second spring 8 will be compressed, so that the entire sealing rod body 1 will enter the device hole of the connector, completing the connection between the sealing rod body 1 and the device hole of the connector. Since the second spring 8 is set, theoretically, the sealing rod body 1 is suitable for the device holes of most connectors.

[0036] The device solves the problem that the traditional wire harness sealing plug cannot meet the docking matching of the wire harness and the connector hole.

[0037] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
