Description
-1 1 - C, ( ' r) r.' 1! MI 52-074 "Electrical Connector" This invention
relates to a connector for electric wires and a method of connecting electric wires by use of such a connector. In particular, the invention relates to a connector for holding electric wires by pressure on the outside thereof and a method of connecting electric wires by use of a connector of this type.
A connection between electric wires is generally achieved by using one or more connectors interposed therebetween, and a connector of this type generally comprises a connecting portion and a crimping or pressing portion. The connecting portion of a connector functions to electrically contact another connector, and the crimping portion thereof functions to electrically contact the electric wire to be connected. The connecting of two electric wires is usually carried out mainly by two methods, one being a method in which a crimping portion is deformed so as to externally surround and hold the electric wire, and the other one being a method in which the crimping portion and the electric wire are soldered to each other in addition to the steps of the first method.
In the first method, however, a complete electric connection between the electric wire and the crimping portion of the connector is not ensured. This may result in a non-conductive condition. Such a non-conductive condition often occurs due to changes over time and the tendency of electrical resistance to gradually increase over time. This is often observed after the use of the connector for about five years.
In the second method, the soldering completes the electrical connection between the electrical wire and the crimping portion. The connection then can stand the changes over time. The soldering, however, requires an additional heating process, which is troublesome and uneconomical. In addition, insufficient soldering results in an inferior product, and accordingly, the yield is lower.
Viewed from a first broad aspect the present invention provides an electrical connector for connecting electrical wires comprising: a connecting portion, a crimping portion attached to said connecting portion and being deformable for holding an electrical wire; and an electrically conductive layer made of plastically deformable material provided on the side of said crimping portion against which the electrical wire will be held in use.
Viewed from a further broad aspect the present invention provides a method of connecting electric wires by an electrical connector having a connecting portion for providing an electrical contact, and a crimping portion for holding the electric wires, comprising the steps of: forming an electrically conductive layer made of easily deformable material on a surface of said crimping portion; placing an electric wire onto said crimping portion; and bending said crimping portion around the wire so as to firmly hold the electric wire by means of the electrically conductive layer and the crimping portion.
Two embodiments of the invention will now be described by way of example and with reference to the accompanying drawings, in which:Fig. 1 is a perspective view showing one embodiment of a connector for electric wires according to this invention; 35 Fig. 2 is a perspective view showing a connection of the connector of Fig. 1 to electric wires; Fig. 3 is a plan view showing a blank of a series of the electric connectors of Fig. 1 prior to severing and bending; 11 i Fig. 4 is a plan view of the connector of Fig. 1 prior to the application of solder and the initial bending for clarity; Fig. 5 is a perspective view showing another embodiment of the connector for electric wires according to this invention; and Fig. 6 is a plan view of the connector of Fig. 5 prior to the application of solder and the initial bending for clarity.
Referring to Fig. 1, female-type connector 1 and male-type connector 2 for joining an electric wire according to one embodiment of this invention are shown. Both connectors 1 and 2 are provided with interference-fit type connecting portions 11 and 21, respectively, and are mutually connected by inserting male connecting portion 21 into female connecting portion 11.
As shown in Fig. 2, in use, the connections between connectors 1 and 2 and electric wires 3 and 4 are made by means of crimping portions 12 and 22 of the respective connectors 1 and 2. Crimping portion 12 of the female-type connector 1 is bent and pressed so as to hold respective halves of wire 3 from both lateral sides. Crimping portion 22 of the male-type connector 2 is also bent shaped and pressed so as to hold the respective halves of the outer periphery of the other wire 4. The female-type connector 1 is further provided with an auxiliary crimping portion 14, in addition to crimping portion 12, so as to ensure the firm securing of wire 3. Auxiliary crimping portion 14 encircles and holds the whole outer peripheral surface of wire 3.
he connectors are also provided with soldered layers 13 and 23, respectively, shown as the hatched portion in the drawings. Soldered layers 13 and 23 are formed inside crimping portions 12 and 22, respectively, as an electrically conductive metal layer. It is preferable to form soldered layers 13 and 23 so as to have horizontal and longitudinal lengths about two-thirds that of crimping portions 12 and 22. Soldered layers 13 and 23, when the connectors are in use, are positioned between electric wire 3 or 4 and the respective crimping portion 12 and 22. The soldered layer can be relatively easily plastically deformed as the crimping portion is deformed.
Accordingly, the plastically deformed soldered layers 13 and 14 fill the spaces formed between wires 3 and 4 and crimping portions 12 and 22, respectively, when the connectors are crimped, whereby wide contacting areas are provided and good electrical conduction is achieved between the electric wires and the crimping portion.
According to the embodiment of Fig. 2 the female- and male-type connectors 1 and 2 are made of brass and insertable into each other, and electric wires 3 and 4 are made of copper, thereby ensuring an ideal electrical contact. The thus made connector may be durable for more than 10 years.
Fig. 5 shows a perspective view of an electrical connector of another embodiment of this invention.
A ring-shaped connector 5 comprises a connecting portion 51, a crimping portion 52, and an auxiliary crimping portion 54, all being made of aluminium, and a soldered layer 53 formed on the inside of crimping portion 52. The connecting portion 51 is secured to another connector by means of a small connecting screw, for example. Crimping portion 52 is adapted to crimp the electric wire in a manner such that the portion 52 holds the exterior of the wire as in the embodiment of Fig. 2. The connector 5 of this embodiment is designed as an aluminium connector. The electrical conductivity is better than that of the traditional connector having no soldered layer. However, in comparison 1 1 c with the first embodiment in which the connector is made of brass and provided with the soldered layer, the electrical conductivity is relatively low.
in general, a connector for an electric wire is desirably made of a material or substance possessing a relatively small electrical resistance, such as brass, and made of a light metal.
rig. 4 shows a plan view of the female-type connector 1 of Fig. 1 being cut or punched out so that a plurality of connectors 1 are connected in series of through joining portions 15.
In order to fabricate the female-type connector 1 of Fig. 1, after cutting out the multiple-connector blank, and soldered layer 13 is formed on the respective crimping portions 12. Then connecting portions 11 are bent inwardly as shown in Fig. 1 by means of a pressing machine. The crimping portions 12 and the auxiliary crimping portions 14 are also bent into a U-shape, and the joining portions 15 are finally cut to obtain the separate female-type connectors 1.
In addition, it is desirable to provide recesses or cut-outs 16 as shown in Fig. 4, or sharp projections 17 as shown in Fig. 6, on the upper surface of the crimping portion 12. These provisions facilitate the plastic deformation of the soldered layer 13 and the firm engagement between the surfaces of the crimping portion 12-and the soldered layer 13, when the crimping portion 12 is bent into a U-shape as shown in Fig. 1. The soldered portion 13 is thereby prevented from being disengaged or dropping out from the inside of the crimping portion 12.
1 It is to be noted by those skilled in the art that the foregoing disclosure will, of course, be easily applicable to the male-type connector 2 in substantially the same manner as described hereinabove.
As described hereinbefore, sufficient electrical contact can be attained by,providing soldered layers 13 and 23 inside the crimping portions 12 and 22, respectively, even in a relatively small contact- type connector for connecting electric wires in which sufficient contact could not be attained by conventional crimping means. In addition, the infusion of a flx into soldered layers 13 and 23 makes it possible to carry out the fusing operation by heating the same.
Although embodiments in which soldered layers are formed have been described hereinabove, it should be understood that according to this invention, other variations and modifications, such as use of another easily plastically deformable metal such as brass or the like as the electrically conductive layer, are possible.
By means of this invention, at least in its preferred forms, layers of metallic material are disposed on the crimping portions of connectors for electric wires, the desired electrical contact between the crimping portions and the electric wires can be achieved without performing an additional heating step.
it is to be clearly understood that there are no particular features of the foregoing specification, or of any claims appended hereto, which are at present regarded as being essential to the performance of the present invention, and that any one or more of such features or combinations thereof may therefore be included in, added to, omitted from or deleted from any of such claims if and when amended during the prosecution of this application or in the filing or proecution of any divisional application based thereon.
