Description

Electrical connector suitable for transmitting high voltage current

Technical Field

The utility model relates to an electrical equipment field, in particular to be suitable for electric connector of conveying high voltage electric current.

Background

To carry high voltage currents, the supply lines usually have a large diameter, for example more than 10mm²Cross section ofArea. In the field of chip manufacturing, vacuum laminators are commonly used to make prepregs used as the base material of chips. Various heating pipes are densely arranged in the vacuum laminating machine, and the heating pipes are electrically connected by power wires. In the prior art, the cross-sectional area between adjacent heating pipes in a vacuum laminator is 12mm²Or a cylindrical power cord of greater cross-sectional area. Although the power line is provided with the high-temperature-resistant mica outer layer, in the actual working state of the vacuum laminating machine, the heating pipe connected with the power line is heated to over 400 ℃, so that the power line cannot meet the long-term normal work of the vacuum laminating machine. After a limited number of uses, the power cord still needs to be replaced. Therefore, the worker needs to spend more time per month to replace the power cord, which results in higher maintenance cost and lower operation productivity of the vacuum laminator.

In particular, in the partial vacuum laminator, the interval between the respective heat pipes is small, and the bending amplitude of the power supply line connecting the heat pipes is large. The labor required to bend the power cord in a straight line to a required arc before the worker replaces the power cord further increases the maintenance cycle and cost of the vacuum laminator.

Therefore, it is necessary to modify the existing power cord.

The utility model aims at realizing through the following technical scheme: an electrical connector adapted to carry high voltage electrical current, wherein the electrical connector comprises a plurality of conductive wafers.

The first end portions of the respective conductive sheets are in laminated contact with each other, the second end portions of the respective conductive sheets are in laminated contact with each other, and the intermediate portions of the respective conductive sheets are isolated from each other, thereby making it easy for the electrical connector to be bent at the intermediate portions.

In the electric connector in which a plurality of conductive sheets are laminated, the respective conductive sheets are spaced apart from each other at the intermediate portion, so that the electric connector is still easily bent. This allows a worker to easily disconnect and connect the electrical connector without moving the two items to which the electrical connector is connected.

Detailed Description

The inventive concept will be described in detail below with reference to the accompanying drawings. What has been described herein is merely a preferred embodiment in accordance with the present invention, and those skilled in the art will appreciate that other ways of implementing the present invention on the basis of the preferred embodiment will also fall within the scope of the present invention. In the following detailed description, directional terms, such as "upper", "lower", "inner", "outer", "longitudinal", "lateral", and the like, are used with reference to the orientation depicted in the accompanying drawings. The components of embodiments of the present invention can be positioned in a number of different orientations and the directional terminology is used for purposes of illustration and is in no way limiting.

Fig. 1 is a front view of an electrical connector 1 according to a first preferred embodiment disclosed; fig. 2 is a left side view of the electrical connector 1 according to the first preferred embodiment of the present disclosure. As shown in fig. 1 and 2, an electrical connector 1 suitable for carrying high voltage electric current has a plurality of conductive sheets 10, the conductive sheets 10 being, for example, conductive copper sheets or other conductive members in the form of sheets having a characteristic of being easily bent. Wherein each of the respective conductive sheets 10 includes a first end portion a, a second end portion B disposed opposite to each other in the length direction, and a middle portion C interposed between the first end portion a and the second end portion B. The first end portions a of the respective conductive sheets 10 are in laminated contact with each other, the second end portions B of the respective conductive sheets 10 are in laminated contact with each other, and the intermediate portions C of the respective conductive sheets 10 are isolated from each other, so that the electrical connector 1 is easily bent at the intermediate portions C.

In some embodiments, the conductive sheet 10 may have a uniform thickness at different locations along its length. After the first end portion a and the second end portion B of each conductive sheet 10 are coated with the conductive paste, the worker laminates the first end portion a and the second end portion B of the conductive sheet 10 by using a laminator. It will be appreciated that the conductive adhesive should have a greater thickness to ensure that the intermediate portions C of the respective conductive sheets 10 do not contact each other after the conductive sheets 10 of the respective layers are laminated. The thickness of the conductive paste is, for example, 3mm, 5mm, or the like.

In other embodiments, the conductive sheet 10 may have different thicknesses at different locations along its length. More specifically, the thickness of the first end portion a of the conductive sheet 10 and the thickness of the second end portion B of the conductive sheet 10 are set to be larger than the thickness of the middle portion C of the conductive sheet 10. At this time, after the conductive sheet 10 is heated at a high temperature, the conductive sheet 10 is softened to a certain degree and then laminated by a laminating machine to be fixedly connected with each other, so as to ensure that the first end portion a and the second end portion B of each conductive sheet 10 are connected with the first end portion a and the second end portion B of the conductive sheet 10 of the adjacent layer in an embedded manner. Optionally, the first end portion a and the second end portion B of each conductive sheet 10 may also be coated with a conductive adhesive and then laminated for fastening. It is to be understood that in this embodiment, the thickness of the conductive paste is set to have a small thickness, for example, 0.2mm, 0.3mm, or the like.

In the case of the conductive sheet 10 having a non-uniform thickness, a worker does not have to strictly control the pressure of laminating the conductive sheet 10 in the process of preparing the electrical connector 1, and thus the electrical connector 1 can be prepared more easily.

The distance between the intermediate portions C of the conductive sheets 10 of the respective adjacent layers in the electrical connector 1 is inversely proportional to the total length of the electrical connector 1. That is, the longer the total length of the electrical connector 1, the smaller the pitch can be set between the conductive sheets 10 of adjacent layers; conversely, the shorter the total length of the electrical connector 1, the larger the pitch between the conductive sheets 10 of the adjacent layers can be set. Therefore, the electric connectors 1 with different lengths can be conveniently bent and deformed.

To further improve the adaptability of the electrical connector 1 of the present disclosure, the individual conductive sheets 10 of the electrical connector 1 may be set to have different degrees of softness. Specifically, the plurality of conductive sheets 10 have first conductive sheets 11, 11 'having higher softness than the other conductive sheets 13 and second conductive sheets 12, 12' having lower softness than the other conductive sheets 13. Therein, in some embodiments, a first conductive sheet 11, 11 'is positioned on one side surface of the electrical connector 1, while a second conductive sheet 12, 12' is positioned on the other side surface of the electrical connector 1. The first conductive foil 11, 11 'allows the maximum bending amplitude compared to the other conductive foils 13, while the second conductive foil 12, 12' allows the minimum bending amplitude compared to the other conductive foils 13. The worker can bend the electric connector 1 toward the second conductive sheet 12, 12' side more easily the electric connector 1.

In order to facilitate the identification of the first conductive foils 11, 11', the second conductive foils 12, 12' of the electrical connector 1 by the operator, different markings may be provided on the first conductive foils 11, 11', the second conductive foils 12, 12', for example different colours, markings or the like on the corresponding conductive foils 10.

In a preferred embodiment, the softness of each conductive sheet 10 increases in the thickness direction from the first conductive sheet 11, 11 'to the second conductive sheet 12, 12'. It should be noted that this sequentially increasing softness does not only mean that the softness of each conductive sheet 10 is different, but that some of the conductive sheets 10 may have the same softness, provided that the tendency of the softness of the conductive sheets 10 to change is satisfied. For example, in some embodiments, electrical connector 1 has 6 layers of conductive sheets 10, and conductive sheets 10 have four softness H1, H2, H3, H4, wherein H1-H4 decrease in sequence. At this time, the softness of the first conductive sheets 11 and 11 'is H1, and the softness of the second conductive sheets 12 and 12' is H4. And among the 4 other conductive sheets 13 interposed between the first conductive sheets 11, 11 'and the second conductive sheets 12, 12', in one embodiment, the softness of the 2 conductive sheets 13 adjacent to the first conductive sheets 11, 11 'may be set as H2, and the softness of the 2 conductive sheets 13 adjacent to the second conductive sheets 12, 12' may be set as H3. In other embodiments, the softness of 3 conductive sheets 13 adjacent to the first conductive sheet 11, 11 'may be set as H2, and the softness of 1 conductive sheet 13 adjacent to the second conductive sheet 12, 12' may be set as H3. Besides, the electrical connector 1 in the form of 6 conductive sheets can alternatively be configured with 6 conductive sheets 10 of different softness.

Although the above describes an embodiment in which the first conductive sheets 11, 11 'of maximum softness and the second conductive sheets 12, 12' of minimum softness are arranged on opposite sides of the electrical connector 1. However, embodiments in which only one (or one group) of the first conductive sheets 11, 11 'and the second conductive sheets 12, 12' is disposed on one side surface of the electrical connector 1 are all the inventive concepts sought to be protected by the present disclosure. For example, one or a plurality of first conductive sheets 11, 11' arranged in layers (in "layers" in the thickness direction) are provided on one side surface of the electrical connector 1, while the remaining conductive sheets 13 are provided to have the same softness.

According to the present disclosure, the value of the softness of the conductive sheet 10 may be achieved by setting the thickness and/or width of the conductive sheet 10. The thickness direction of the conductive sheet 10 (electrical connector 1) can be seen in the Z-axis direction of fig. 2, the width direction of the conductive sheet 10 (electrical connector 1) can be seen in the X-axis direction of fig. 1, and the length direction of the conductive sheet 10 (electrical connector 1) can be seen in the Y-axis direction of fig. 1 and 2.

In the case where the softness of the first conductive sheet 11, 11 'is greater than the softness of the second conductive sheet 12, 12', the thickness of the first conductive sheet 11, 11 'has a thickness less than that of the second conductive sheet 12, 12' (see fig. 1); or the width of the first conductive sheet 11, 11 'has a smaller width than the second conductive sheet 12, 12' (see fig. 3); or the thickness of the first conductive sheet is smaller than the thickness of the second conductive sheet 12, 12', and at the same time, the width of the first conductive sheet is smaller than the width of the second conductive sheet 12, 12' (see fig. 3). For embodiments of the conductive sheet 10 configured to have different widths, see FIG. 3.

For the electrical connector 1 of the present disclosure, the number of the conductive sheets 10 is preferably set in the range of 3-8, such as 4, 5, 6, etc., so as to satisfy that the electrical connector 1 can have appropriate softness on the premise that the electrical connector 1 satisfies normal passage of high-voltage current.

The thickness T of the electrical connector 1 is preferably set in the range of 3mm-5mm, such as 4.2mm, 4.5mm, etc.

The length L of the electrical connector 1 is preferably set in the range of 80mm-150mm, such as 90mm, 100mm, 120mm, etc.

The width W of the electric connector 1 is preferably set in the range of 12mm to 30 mm.

With the electrical connector 1 of the above form, the electrical connector 1 can obtain a good balance in conductivity and softness.

Further referring to fig. 1, 3, the electrical connector 1 is optionally formed with through holes 14 at the first end a, the second end B. The through hole 14 may be used as a connection contact for connecting a heat pipe or a joint for other items requiring electrical connection.

Alternatively, the electrical connector 1 may be provided with a wire nose at one or both of the first end a, the second end B. The electric connector 1 can be electrically connected with other articles needing electric connection through the wire nose.

In the electric connector 1 in which the plurality of conductive sheets 10 are laminated, the respective conductive sheets 10 are spaced apart from each other at the intermediate position, so that the electric connector 1 is still easily bent. This enables a worker to easily detach and attach the electrical connector 1 without moving the two items to which the electrical connector 1 is connected.

Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications and variations can be made in the embodiments or in part of the technical features of the embodiments without departing from the spirit and the principles of the present invention.
