DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described with reference to the drawings.
[0016]
The welding connector according to this embodiment assumes a welding connector having a plurality of drain contacts to which drain lines are connected and signal contacts to which signal lines are connected. Here, the signal line is a cable for transmitting a data signal, and the drain line is a cable for connecting to the ground.
[0017]
FIG. 1 shows the structure of a batch resin mold portion 1 manufactured by inserting a heat-resistant plate of a welding connector into a resin and molding the resin collectively.
[0018]
That is, the collective resin mold portion 1 includes a heat resistant plate (for example, ceramic) 3 and a resin portion 5. Moreover, by manufacturing by the batch resin mold as described above, the batch resin mold portion 1 having high strength and stability is manufactured by the heat resistant plate 3 and the resin portion 5 in which the heat resistant plate 3 is inserted and solidified. Is done.
[0019]
Please refer to FIG. An example is shown in which contacts (for example, drain contacts and signal contacts) for connecting cables are assembled to the collective resin mold portion 1 described in FIG.
[0020]
By assembling a plurality of contacts into the collective resin mold portion 1, the welding connector has a predetermined structure.
[0021]
That is, a plurality of drain contacts and a plurality of signal contacts are supported on the heat-resistant plate 3 of the collective resin mold portion 1. Thereby, it becomes a structure without a backlash etc., and stability of a transmission characteristic, connection strength, etc. can be aimed at.
[0022]
More specifically, drain contacts 9 are supported at equal intervals from the drain contact 7 supported on the heat resistant plate 3. Further, the drain contact 11 is supported at equal intervals from the drain contact 9 (that is, the distance DC between the center of the thickness of the drain contact 7 and the center of the thickness of the drain contact 9 is the center of the thickness of the drain contact 9). And the distance DD from the center of the thickness of the drain contact 11).
[0023]
Here, in FIG. 2, two types of drain contacts are shown for convenience of explanation. A normal drain contact has a hole shape for inserting a heat-resistant plate (see drain contact 11).
[0024]
On the other hand, since the heat-resistant plate 3 and the resin are molded together as in the present invention, it is not necessary to drill holes in the drain contact, and the rod-shaped drain contacts 7 and 9 can be changed. Here, a rod-shaped drain contact is illustrated as an example, but various shapes depending on the function are within the technical scope of the present invention.
[0025]
Return explanation. Although not shown in FIG. 2, a predetermined number of drain contacts are supported on the heat-resistant plate 3 while maintaining the positional relationship as described above.
[0026]
A signal contact 13 and a signal contact 15 are provided at the center between the drain contact 7 and the drain contact 9. That is, the distance DA between the center of the drain contact 7 and the centers of the signal contacts 13 and 15 is equal to the distance DB between the center of the drain contact 9 and the centers of the signal contacts 13 and 15.
[0027]
Here, the signal contact 13 is provided on one surface A of the heat resistant plate 3, and the signal contact 15 is provided on the other surface B of the heat resistant plate 3. A plurality of signal contacts are supported by the heat-resistant plate 3 while maintaining the positional relationship as described above.
[0028]
The heat-resistant plate 3 is made of ceramic, but may have heat resistance such as porcelain or earthenware. This is because it is strong against heat generated during electric welding and is economical from the viewpoint of cost.
[0029]
Please refer to FIG. An example in which the above-described welding connector has other functions is shown. The collective resin mold portion 21 shown in FIG. 3A has a resin portion 23 and a heat resistant plate 25. When the heat resistant plate 25 is inserted and batch resin molding is performed, a plurality of pin insertion holes 27 into which drain contacts and signal contacts are inserted are formed in the resin portion 23. Thus, after the heat-resistant plate 25 is inserted and the batch resin molding is performed, the pins (drain contact, signal contact) can be assembled easily and accurately.
[0030]
The collective resin mold portion 31 shown in FIG. 3B has a resin portion 33 and a heat resistant plate 35. Then, the heat-resistant plate 35 is inserted and batch resin molding is performed. The heat-resistant plate 35 inserted in the resin portion 33 is not only flat, but also has a heat-resistant property such as when a groove or the like is provided in the heat-resistant plate 35 for the purpose of positioning a contact (drain contact, signal contact) or the like. The present invention can also be applied when the shape of the plate 35 becomes complicated. That is, although it is difficult to assemble the heat-resistant plate 35 having a complicated shape, the heat-resistant plate 35 and the resin portion 33 can be integrated and the welding connector can be easily stabilized by batch molding with resin. .
[0031]
Here, description will be given of positioning the contact (for example, drain contact, signal contact) by providing the groove portion 37 in the heat resistant plate 35. For example, the heat resistant plate 35 is provided with a plurality of groove portions 37. A contact (for example, drain contact, signal contact) is positioned in each groove portion 37 and a cable (for example, drain line, signal line) 41 that contacts the contact is positioned. As a result, the positional relationship between contacts, cables, etc. is accurately maintained.
[0032]
In the above, the heat-resistant plate 35 has a shape having a plurality of grooves, but the technical scope of the present invention also applies to an insert resin portion in which a heat-resistant plate having a shape corresponding to various functions is inserted and batch resin molding is performed. Is within.
[0033]
In addition, this invention is not limited to the example of the embodiment mentioned above, It can implement in another aspect by adding an appropriate change.
[0034]
【The invention's effect】
As described above, according to the present invention, for example, a heat-resistant plate (for example, ceramic) and a resin are collectively molded, so there is no play of the heat-resistant plate as in the present, and transmission characteristics and connection strength are stable. Is effective.
[0035]
In addition, since the heat-resistant plate and resin are molded together, there is an effect of reducing defects (such as folding the contact when the heat-resistant plate is inserted) due to post-processing (insertion of the contact and heat-resistant plate). . Furthermore, even when the heat-resistant plate is provided with a groove or the like and becomes a complicated shape, the connector can be easily stabilized by integrating the resin with the resin by batch molding with the resin.
[0036]
And since the heat-resistant plate and resin are molded together, there is no need to drill holes for inserting ceramic into the conventional contact (drain contact), the contact strength is increased, and transmission characteristics are also advantageous. effective.
