Definitions

  • the present invention refers to a connector specially designed to receive flat cables and allow ultrasonic welding thereof with the terminals.
  • This connector with a modification in the protective cap can also be used for the connection of round and even flat and round cables, becoming a mixed connector.
  • the constitution of the connector claimed by the aforementioned model has been modified, incorporating certain practical advantages, based mainly on the modification of the base piece of the connector, as well as on the introduction of projections that will serve as a guide for the flat cable.
  • the recommended invention introduces multiple advantages over these already known connectors, as can be seen herein.
  • the flat cable connector for ultrasonic welding recommended has a support for the introduction of a flat cable with a certain number of tracks and the same number of electrical terminals for the subsequent application of welding.
  • the connector is made up of different parts that will be assembled to adjust the flat cable and the corresponding terminals allowing its welding later. It is based on a female module that has a slightly prismatic shape and with two different surfaces located at a different height, the lower one being larger than the upper one.
  • the lower surface has a series of longitudinal and parallel ribs or ribs that will give rise to different intermediate spaces in which each of the tracks in the uncoated area of the flat cable, as well as the terminals, will be introduced for subsequent welding.
  • the assembly sequence is as follows, first the terminal is introduced into the cavity reserved for its location, then the flat cable, without stripping, is placed on the tracks reserved for its location and finally welding between the cable and terminals .
  • Ultrasonic welding thanks to the connector design, will be carried out both from the top of the connector and from the bottom, through the existing windows in the connector. Once the welding is done, the female terminal with the wires will be inserted into the receptacle or receiver designed for this purpose and that will protect the welding area that it covers.
  • the projections at both ends, will reduce their height to that of the lower surface, allowing the perfect coupling of the flat cable, which is configured according to the design and dimensions of the projections, having three different parts, a first of the same width as the space between the projections and the connector and that will allow the perfect coupling of the flat cable to the connector, an intermediate zone in which the flat cable without coating is presented, and a third area, of greater size that will be the one protrudes from the male connector, allowing its use.
  • the connector windows are arranged in the same number as the flat cable tracks and the terminals to be connected. Configuring in the intermediate part of both surfaces, which will have sufficient height to house the flat cable and the terminal, the same number of windows or cavities in order to allow the terminal connector to be inserted.
  • the connector also has a protective cover that will fit perfectly with the top and bottom of the connector base allowing to obtain a perfectly closed box, protecting the welding area, and carrying said cover incorporated a "secondary lock", responsible for carrying out A second retention. Finally, the box will be attached to the receptacle or male connector, fixing the connector where appropriate.
  • a mixed connector can be designed, in which flat cable and round cable can be located. The physical arrangement of the connector would be the same as that designed for the flat cable but with the particularity that flat and round cables may be introduced.
  • the way to fix the terminals of the flat cable to the connector will be the same as described above, and the way to fix the round cable will be by introducing the terminal, which has each round cable inserted at its end, in each space fixed for it.
  • the round cables will be perfectly delimited by the projections or ribs described above, and with the end inserted in the cavities of the connector reserved for it.
  • this new invention it is possible to correctly position the terminal and prevent the welding from being incorrect, in addition it also allows to correctly position the flat cable, which also ensures that the welding is correct, gives greater tensile strength to the junction zone of the terminal with the flat cable, the welding zone is protected by the protective cover and a second retention is introduced the terminal into its cavity which is carried out by the protective cover.
  • Figure 1 shows a view of the connector base.
  • Figure 2 shows a view of the connector base once the terminals are inserted therein.
  • Figure 3 shows a view of the connector base after inserting the flat cable.
  • Figure 4 shows a rear view of the connector with the flat cable housed in it.
  • Figure 5 shows a view of the connector after coupling the element that performs the function of protecting the weld, which also includes the second retention element between the terminal and its cavity.
  • Figure 6 shows a view of the connector once housed in its receptacle.
  • Figure 7 shows a view of both round and flat terminals and wires inserted into the connector.
  • Figure 8 shows a figure of the connector protected by the cover.
  • the flat cable connector has a slightly prismatic surface base (figure 1), female module, which has two different surfaces, the lower one being larger than the upper one and where the lower surface has a series of longitudinal projections 1 that they will give rise to different zones or intermediate spaces 2 in which the terminals 3 will first be introduced, which will fit and be held in the cavities 4 located between the lower and upper surface of the base (figure 1) of the connector, space that will have the appropriate height to allow the flat cable 5 and the terminals 3 to be accommodated.
  • a slightly prismatic surface base (figure 1), female module, which has two different surfaces, the lower one being larger than the upper one and where the lower surface has a series of longitudinal projections 1 that they will give rise to different zones or intermediate spaces 2 in which the terminals 3 will first be introduced, which will fit and be held in the cavities 4 located between the lower and upper surface of the base (figure 1) of the connector, space that will have the appropriate height to allow the flat cable 5 and the terminals 3 to be accommodated.
  • the flat cable 5 will be located at the base of the connector, the area without insulating sheathing 6 coinciding with the intermediate spaces 2 left by the projections 1 and thus joining each of the tracks of flat cable 5 and terminals 3 for later ultrasonic welding.
  • the upper surface of the connector base (figure 1) has windows of the connector 7 with the same number as the flat cable tracks 5 and the terminals 3.
  • the flat cable 5 has three different parts, one of smaller size 8 that will fit in the connector in the area left by the projections 1 as these decrease in height, which will allow the perfect coupling of the flat cable 5.
  • the second zone of the flat cable 6 is constituted by the uncoated area of the flat cable 5, thus allowing the welding of each of its tracks with the terminals 3.
  • the flat cable 5 has a third area 8 of larger size which will be the one that protrudes from the connector allowing its use.
  • the connector base will be covered with the protective cover 9, fully adjusting the connector, which will be introduced in the appropriate receptacle 10 preventing the welding performed from being damaged.
  • Another preferred embodiment consists in using the same connector that allows to insert flat and round cable.
  • the shape of the connector will be that described in Figure 7 where you can see how the placement of the terminal 3 and then the flat cable 5 is carried out and finally the ultrasonic welding.
  • the cover 12 is placed, located on the contact area with the terminals and adapting the thickness of the cables .

Abstract

L'invention concerne un connecteur de câble plat pour soudure ultrasonique du type conçu pour recevoir des câbles plats pouvant être soudés par ultrasons aux terminaux correspondants et qui, grâce à des épaulements situés dans le connecteur, permet un ajustement intégral et, par conséquent, une soudure adéquate du câble plat et des terminaux, ledit connecteur comprenant également une gaine de protection destinée à protéger la soudure. Ce connecteur permet non seulement la soudure de câbles plats, mais également de câbles ronds, à condition que les réglages nécessaires soient effectuées dans le connecteur.
