Definitions

  • the present invention relates to a connecting terminal for electric apparatus of the type comprising a plate-like body engaged to an electric apparatus and adapted to define a contact with an end portion of an electric thread-like conductor.
  • connecting terminals for electric apparatus and devices such as switches, double-throw switches, optical signallers, pressure meters, thermostats and in general all components passed through by medium-intensity current flows, say until 16 A, as it happens for example in the field of household appliances, consist of flat connectors each formed with a plate-like body made of a material having a high electric conductivity, engaged to the apparatus itself and emerging therefrom.
  • Ending at said plate-like body is the bare end portion, that is devoid of the outer insulating sheath, of a thread-like electric conductor of the rigid or flexible type, which is to be connected thereto.
  • Connections of a thread-like electric conductor to said plate-like bodies may take place according to different modalities in order to ensure an appropriate electric contact in time, avoiding any slackening which will bring about sparkings between the parts above all in the presence of vibrations or tractive stresses in use.
  • connection element integral with the ends of the thread-like conductor and adapted to be fitted on the flat connector of the apparatus.
  • This known connecting element is substantially formed with a plate having, at one end, a hooking appendage clasping the end portion of the thread-like electric conductor, devoid of the insulating sheath and, at the other end, two spaced apart and undulated portions.
  • interposing a connecting element between a thread-like electric conductor and a flat connector integral with the electric apparatus means that an additional cost, say of the further component, is to be added to the total manufacturing costs, and this charge, although reduced, may affect production.
  • the cited connecting elements sometimes give rise to problems also from an operating point of view.
  • the hooking appendage may be bent, which however brings about the risk of the undesired formation of breaks or cuts, or the risk that said appendage may get too close to conductive parts of the apparatus. Under these situations it is therefore necessary to protect the end portion of the hooking appendages with insulating elements, which operation involves further and undesired costs and workings.
  • the forced fitting does not always give an appropriate ensurance against slackening in the connection.
  • important inaccuracies in construction may occur which condition the degree at interference created between the parts to be mutually engaged.
  • Another known modality for mechanically and electrically engaging a thread-like conductor to a flat connector of an electric apparatus often consists of a direct welding of the above components.
  • both the above described modalities in case of servicing interventions in which it is for example necessary in an apparatus to restore the electric connection between a conductor and a new flat connector of a device that has been replaced, involve the knowledge by the operator of the type of connection he must make, so that he may have at his disposal either the welding equipment or the specific connecting element to be engaged to the end portion of the thread-like electric conductor.
  • the general task of the present invention is to provide a connecting terminal for electric apparatus capable of substantially obviating the above drawbacks.
  • a connecting terminal for electric apparatus characterized in that said plate-like body comprises at least one shaped portion formed by blanking from the body itself and adapted to define a fitting seat for said end portion of the tread-like electric conductor, and in that said shaped portion can be deformed by squeezing so as to secure said end portion of the thread-like electric conductor introduced into said fitting seat, to said plate-like body in a stable manner.
  • the connecting terminal for electric apparatus has been generally identified by reference numeral 1.
  • It comprises a plate-like body 2, made of a material having a high electric conductivity and engaged to one electric apparatus or device 3.
  • the plate-like body 2 pratically is designed to form a substantially flat connector for a thread-like electric conductor 4 coated with an insulating sheath 5 and exhibiting a bare end portion 6, that is a portion from which the sheath has been removed.
  • a plurality of shaped portions 7 each defined by a curved strip is formed in the plate-like body 2 by blanking and subsequent deformation.
  • each shaped portion 7 is obtained by straight cuts 7a parallel to each other, formed in the plate-like body 2, each of which defines two adjacent shaped portions.
  • each cut 7a is made in the form of a transverse slot having such a width that the facing edges of two contiguous shaped portions 7 are suitable spaced apart from each other.
  • the shaped portions 7 are parallel to each other and alternately emerge from opposite faces of the plate-like body 2, practically defining a substantially tubular fitting seat 8 into which the end portion 6 of the thread-like electric conductor 4 can be easily introduced.
  • the shaped portions 7 are deformed by squeezing and they will therefore tend to flatten, and the shaped portions emerging from one face of the plate-like body 2 will tend to move close to the shaped portions projecting from the second face of the same plate-like body, taking substantially a coplanar position with respect to each other.
  • the conductor 4 is fixedly engaged to the connecting terminal and can resist high tractive efforts without the occurrence of slackenings or separations therefrom.
  • the invention achieves important advantages.
  • the connecting terminal of the invention does not require the presence of connecting elements interposed between the terminal itself and a thread-like electric conductor.
  • clamping of the end portion of a thread-like conductor made by the connecting terminal in accordance with the invention is very safe and steady even in the presence of vibrations, because the clamping force achieved between the deformed shaped portions of the connecting terminal and the end portion of the conductor is very high.
