Description

DESCRIPTION

  The present invention relates to a printed circuit socket whose new construction, conformation and configuration characteristics fulfill the purpose for which it was specifically provided, with a safety and a reliability.

maximum efficiency.

  In the technical field of printed circuits, there is a series of elements that are mounted on them, such as low and medium power sockets. Said sockets are inserted, fixed and welded on the conductive parts of the printed circuit and serve as support and connection elements for the corresponding male terminals which are fixed on the ends of the wires.

  corresponding drivers or on different electronic modules.

  Among the printed circuit sockets, there are various differentiated types

  both by their shape and by their latching system in the printed circuit.

  Traditionally, this type of socket has two distinct parts, a lower formed by one or more tabs which are inserted into the printed circuit to be welded thereafter, while the opposite upper part is formed by two metal strips which meet in one. point identical to that o

  is inserted the male terminal, and is held firmly by said metal slats.

  The current trend of the various elements that are incorporated into the printed circuit boards is that these, in addition to ensuring a perfect electrical connection, serve as coating elements against external agents, such as dust, dirt and grease. are deposited on the contacts during the incorporation of the printed circuit in a vehicle, which is why an attempt is made to establish an arrangement of said printed circuit sockets which makes it possible to avoid, in the long run, said external agents from damaging the electrical connection between the upper part of said printed circuit socket and the male terminal which is

  applied between the slats which form said upper part.

  In another technical order, when incorporating the quality controls into the corresponding manufacturing and processing chain, it is increasingly common for parts found in the random process to be submitted to corresponding checks to verify that their technical specifications

  are actually those programmed.

  For this reason, the closed bushing such as that which will be described later includes a configuration which allows on the one hand the perfect protection of the contacts of said bushing and the male terminal, as well as a circular window in one of its lateral parts. , so that random quality checks can check the distance between the two metal strips between which is the

male terminal.

  The invention relates to a printed circuit sleeve, of the type formed from a lamella or metal plate by forming and folding, forming a single body whose end or insertion pin is inserted into a printed circuit, while that the other end receives a male terminal mounted in the end of a traditional electrical conductor or an electronic module, characterized in that the sleeve has three different zones, an anterior or terminal male area, a median configuration zone essentially regular tetrapyramidal and a posterior prismatic area, which comprises the corresponding means of control of

  quality as well as the means of compensation of the axial stresses.

  Advantageously, the front part of the sleeve is formed by

  folding a plate shaped into an insertion pin.

  The central zone of the printed circuit sleeve essentially of regular tetrapyramidal configuration is formed by two major bases which form inclined anterior planes extending the major bases while their

  side faces are formed by triangular fins.

  Thus, the socket at the recommended power has in its posterior part an essentially prismatic configuration while, in its middle part, it has a regular tetrapyramidal configuration, from which emerges in its lower part the male terminal which is inserted at its end into the circuit

  corresponding print to be soldered to it later.

  The posterior zone of the sleeve has an essentially prismatic configuration formed by an upper base, a lower base and two lateral faces, the upper and lower bases being extended inward by means of contacts in the form of inclined planes which are terminated by flanges

  directed to the bases and between which the corresponding male terminal is introduced.

  The means of quality control of the socket are formed by

  circular bores formed in the lateral faces of the central zone of the sleeve.

  Preferably, one of the lateral faces of the rear portion has near its minor lateral base a bore or circular window which allows a quality control during the corresponding manufacturing process. The upper base is reinforced by means of upper ears which serve to prevent the sleeve from opening because of the axial stresses generated by the introduction of a male terminal within the inclined planes which form the electrical contact. Thus, the stress compensation means of the printed circuit bushing are formed by upper ears formed from the extension of the lateral face which are superimposed on upper stampings.

practiced on the upper base.

  Other details and features of the present invention will become apparent

  more clearly with the following description, in which reference is made to

  attached drawings in which the preferred details are represented in a somewhat schematic way. These details are given as an example and refer to a case

  possible practical embodiment of the present invention which is not limited thereto.

  This description must therefore be considered from an illustrative point of view and without limitation

of any kind.

  It is now a detailed statement of the various elements that are mentioned in the present invention: socket (10) for printed circuit board, upper base (11), lower base (12), lower stamping (12.1), right side face (13) ), left side face (14), upper ears (15), insertion pin (16), folded plate (16.1), contacts or beams (17), flanges (17.1), circular window (18),

  triangular fins (19), upper stamping (20), front planes (21).

  Figure 1 is an asymmetrical perspective view of the power socket (10); Figure 2 is a longitudinal sectional view from above and from the side of the sleeve (10) for printed circuit; Figure 3 is a side elevational view of the printed circuit sleeve (10); Figure 4 is a top plan view of the power socket (10); Figure 5 is a section along the line 5-5 of Figure 4;

  Figure 6 is a section along the line 6-6 of Figure 4.

  In one of the preferred embodiments of the subject of the present invention and as can be seen in Figure 1, the sleeve (10) for printed circuit has three different parts, a substantially prismatic posterior zone, a zone median tetrapyramidal regular and anterior area that is consistent with

  means of an insertion pin (16).

  The posterior prismatic portion is essentially formed by an upper base (11) and a lower base (12) parallel to one another and two lateral faces

  right and left (13) and (14) respectively.

  The upper and lower bases (11) and (12) are extended at their ends by inclined planes or contacts (17) which have at their ends

  ledges facing the bases (11) and (12).

  The lateral face (14) is extended by upper ears (15) which form a right angle with the lateral face (14) and which bear on the lower part

  (11) by means of the upper draws (20).

  On the lateral face (13), a circular bore (18) has been made which, on the continuous production and conformation line, serves as an auxiliary element to the

  checking the separation between the contacts (17).

  The central zone of the terminal (10), of regular tetrapyramidal configuration, has lateral bases formed by triangular fins (19) and this median zone of the sleeve (10) is extended by an insertion pin (16) formed

  by means of a folded plate (16.1), as can be seen in FIG.

  The configuration described above forms a single whole (10) completely closed, so that the male terminal mounted outside the cable or the electronic module is placed by means of the area limited by the contacts (17), lightly pressing on these to the upper base (11) and lower (12), serving as a stop in the extreme positions in the upper draws (20) and the

  lower draws (12.1) corresponding, as can be seen in Figure 2.

  On the other hand, as shown in FIG. 4, the upper base (11) of the bushing (10) is configured so that, in areas contiguous to the upper lugs (15), upper draws (20) are formed. ) which are covered by the lugs (15), thus avoiding that, when introducing a male terminal inside the contacts (17), because of the axial stresses generated, the upper base (11) can be move upward by resisting the said stresses with the

  covering of the ears (15) and the stampings (20) mentioned above.

  The upper (11) and lower (12) bases of the posterior portion of the sleeve (10) are extended forwardly by inclined front planes (21) whose lateral faces are folded to form the corresponding triangular fins (19).

  previously mentioned, as can be seen in Figures 1, 2 and 3.

  The printed circuit sleeve (10) is used as described above.

  below. By means of appropriate machines, normally machines for inserting electrical and electronic components, it is inserted perpendicular to a printed circuit by means of the anterior part, that is to say the insertion pin (16), which crosses normally this circuit board and is then soldered to a part

conductive of it.

  By the rear part, the corresponding male terminal is introduced, so as to make contact between an electrical conductor in the end of said male terminal and the corresponding conductive portion of the printed circuit to which

  assigned a particular function.

  The connection zone being formed by the contacts (17) completely protected against external agents such as dust, dirt, grease and others, but also against the blows that can occur during the mounting of the vehicle, it ensures a high reliability of the printed circuit socket, thanks to its fully prismatic and closed rear zone, it brings degrees of security and reliability totally unknown until now and which exceed the required values of an anomaly per 100,000 manufactured sockets, which is quite usual in

the automobile sector.

  The main quality of the closed form of the socket is that it must be solid because of the stresses experienced when mounting in the circuit board

  printed without damaging the structure.

  We will note after observing the drawings and the explanation that we have

  made of them that the invention which motivates the present description provides a

  simple and efficient construction that can be put into practice with great ease,

  which undoubtedly constitutes a new industrial result.

  In accordance with the detailed description and the attached drawings,

  will understand that any modification considered practical remains possible, without leaving

  of the field of protection of the invention.
