Description

Improved bonder terminal

Technical field

The utility model relates to a kind of line connector, relates in particular to a kind ofly must not weld, and the effect that can be connected with lead is rapidly conveniently being pressed and processed, and makes lead and terminal form dual electric connection, further improves the improved bonder terminal of electrical characteristic.

Background technology

Terminal, does not have terminal that connector will be produced and electrically connects just as the importance of engine to vehicle for the effect of connector.Yet connector species is various, and therefore terminal also has various difformities, but a terminal mostly has the contact site of front end, middle fastening part basically, and the connecting portion of tail end.

As shown in Figure 1, 2, cable connector for existing a kind of SATA (Serial AT Attachment) interface, it is at connector body 11 inner ccontaining a plurality of terminals 12, and the contact site 121 of terminal 12 and fastening part 122 are in body, the connecting portion 123 of tail end then stretches out body, coats processing for remaking follow-up shell after several wires 13 welding.

But, utilize the connecting portion 123 of terminal 12 tail ends to form the mode that electrically connects with lead 13 welding, not only must rely on manually wastes time and energy, and can distribute toxic gas in the welding process, is unfavorable for environmental protection and health.

In addition, because lead 13 is very thin, and the spot size of pad is wayward, yet poor welding spots or not of uniform size all can have influence on electrical characteristic, even makes fraction defective high, and production cost is improved.

Yet, change the connected mode of the structure of terminal 12 or itself and lead 13, the terminal that all must consider connector has a specific specification and a distance, and terminal is to utilize metal (copper sheet) strip and continuously shaped when punch forming, therefore must make it meet the benefit of processing procedure, and the terminal after the moulding must make up with lead is convenient, and can reach the predetermined electrical characteristic, and it is required just to meet industry.

The utility model content

In order to overcome the above-mentioned shortcoming that existing cable connector exists, the utility model provides a kind of improved bonder terminal, and it does not have and must weld, the effect that can be connected with lead rapidly, conveniently pressing and processing, making lead and terminal form dual electric connection, further improving electrical characteristic.

The technical scheme that its technical problem that solves the utility model adopts is:

A kind of improved bonder terminal comprises the contact site of front end, the fastening part of centre and the connecting portion of tail end; It is characterized in that the described tail end Zhe that makes progress works the clamping face that is vertical, clamping face is provided with opening Y shape groove up, and the bottom groove width of Y shape groove is less than the diameter of wire that embeds the location.

Aforesaid improved bonder terminal, wherein terminal is in clamping face the place ahead, and the terminal body both sides upwards are provided with the sheet of pressing of extension, when lead embeds Y shape groove and behind the clamping location, can press coated wire, reach dual electrical contact.

Aforesaid improved bonder terminal wherein is provided with a slice at least in the terminal both sides and is pressing sheet, and is recessed.

Aforesaid improved bonder terminal, wherein the clamping face two bottom sides forms downward protuberant shape body.

Aforesaid improved bonder terminal, wherein the clamping face of each terminals of adjacent is to be staggered form to set.

The beneficial effects of the utility model are that it does not have and must weld, and gets final product the effect that be connected with lead rapidly, is conveniently pressing and is processing, and makes lead and terminal form dual electric connection, further improves electrical characteristic.

Embodiment

At first, see also shown in Figure 3, because the distance D that the contact site of each terminal 2 front end is 21 is that the matching connector (not shown) is required, therefore be subjected to its restriction, and the utility model is under this kind restriction, set by space cleverly, at the tail end 23 of the fastening part 22 of terminal, formation can with the lead structure of combination rapidly.That is the tail end 23 of this terminal 2 is provided with expansion shape clamping face 24.Because the width of clamping face 24 is greater than the width of terminal 2 bodies, for this reason, the tail end 23 ' of adjacent another terminal 2 is given proper extension, and form the form of each clamping face 24 interlaced configuration, this design is not only and is wanted the continuously shaped of complexed metal strip 20, also be when being used in connector after the moulding, can make things convenient for the embedding of each lead to reach the space that does not account for connector.

See also Fig. 4, Fig. 5, shown in Figure 6, tail end 23 of the present utility model and 23 ' upwards curved Zhe are the clamping face 24 of upright expansion shape, and be provided with opening Y shape groove 241 up in clamping face 24, the bottom groove width of Y shape groove 241 such as Fig. 7, shown in Figure 8, diameter less than lead 3, so that can with lead 3 clampings location, form electrically contact by the elastic force of Y shape groove 241.And importantly, this clamping face 24 is curved Zhe and uprightly designs, and makes that lead 3 can be under without any curved Zhe situation, horizontally is connected with terminal 2, and this has good effect for electrical characteristic, can make electrical signal impaired because bend the lead 3 of Zhe.

Moreover this clamping face 24 can form two downward protuberant shape bodies 242 in two bottom sides, this design, as shown in Figure 8, can with connector body 4 assemblings the time, insert the groove 41 that connector body 41 is preset, thus, this vertical clamping face 24 will very firmly be positioned on the connector body.

From the above mentioned, can make the lead 3 rapid Y of embedding shape grooves 241 and form excellent electrical property with terminal 2 to contact, it does not only have solder joint, and Y shape groove 241 is all identical with each terminal 2 contact area, and has the good electrical characteristic.

Further, the another possible embodiments of the utility model during these terminal 2 moulding, is in clamping face 24 the place aheads as shown in Figure 6, pressing sheet 231 by what the both sides of terminal 2 bodies upwards were provided with extension, this is being pressed sheet 231 to be the form that staggers and is setting, and both sides are provided with a slice at least, and slightly slopes inwardly, and in pratical and feasible scope, wherein a side can be provided with two, certainly, is pressing sheet 231 if the space allows both sides can respectively be provided with two.

Because after lead 3 embedded clamping faces 24, lead 3 had been fixedly clamped by level, and forms and electrically connect, this moment, lead 3 was positioned at when pressing sheet 231 middle, can not be offset and slide.Therefore, the clinching body that can conveniently utilize tool or connector itself to be set as will press sheet 231 to be coated on lead 3 tops according to the inwardly curved Zhe of its incline direction.Thus, this terminal 2 is connected except linearly horizontal with lead 3, also has the annexation at clamping face 24 and tail end 23,23 ' two places, reach dual electrical contact, through experiment test, the connected mode of this kind form has very good electric property and mechanical performance.

The feature of above-mentioned terminal except that the connector that can be applicable to the SATA interface, more meets the characteristic important document of multiple connector, really the tool practicality.

In sum, the utility model is on structural design, practicality and cost benefit, and it is required to meet industry development fully, and the structure that is disclosed also is to have unprecedented innovation structure, have novelty, creativeness, practicality, meet the important document of novel patent, so file an application in accordance with the law.

The above, it only is preferred embodiment of the present utility model, be not that the utility model is done any pro forma restriction, every foundation technical spirit of the present utility model all still belongs in the scope of technical solutions of the utility model any simple modification, equivalent variations and modification that above embodiment did.
