Description

The utility model relates to the field of electrical connectors used for installation on garments, for example, on clothes with heating / cooling to ensure the passage of electric current, or on other products in which the electrical connection of the parts is provided.

The purpose of the device dictates the need for a reliable design of electrical push-button connection.

A technical solution is known that relates to the same purpose as the proposed device (description of US patent No. 6642467). This tool contains electrical contacts made in the form of hollow elements with flat surfaces facing each other, as well as clamping elements installed passing into the cavity of the electrical contacts for engagement at their edges. The plate-shaped insulating elements are made of foam material, which has the property of shrinking when a compressive force is applied and returning to its original shape when the force is removed. For the occurrence of contact, causing the flow of current, it is necessary to apply force to compress the insulating elements.

The use of a known electrical connector is associated with the probability of losing the properties of the insulating material, due to which electrical contact is ensured. Therefore, this connection does not have sufficient reliability.

Another technical solution is identified from patent document KR No. 20110009966. The push-button connection includes a plug, a socket associated with electrical contacts. For the connection / connector and being in a fixed position, the plug and socket have surfaces with a complex profile. Therefore, the known technical solution is characterized by the complexity of the design.

From the description of international application WO No. 16099669, an electrical connector is known for use on clothing. This connector contains two fastener buttons integrated into the system, which ensure that current flows in a closed circuit when connecting the mating parts of the buttons and, when they are disconnected, the current in the circuit is stopped.

According to the inventive concept, each button-fastener has options for the implementation of contact parts that ensure the flow of current in the presence of two buttons in the buttoned position (the components are connected) and the termination of the current in the unzipped position of the buttons (the components are disconnected).

When using the button system, a technical problem is detected that impedes the achievement of a technical result.

In particular, the presence of two buttons connected to a current source and a consumer characterizes the known device as complex. Therefore, a malfunction of one of the components of any button leads to inoperability of the entire device.

In addition, the button system is characterized by a low degree of adaptation to the installation site due to the implementation of the device not endowed with the compactness property. For example, to install the button system on the fabric of clothing, you need to choose a place that allows you to place two buttons and connecting elements.

As for the execution of any of the two buttons, then in patent document WO No. 2016099669 several options.

The closest option to the claimed utility model depicted in FIG. 3 of the description of WO No. 2016099669, includes a male part with a flange made of an insulating material, and a female part made of an insulating material. Parts have the shape of a body of revolution. In the first part mentioned, as in the housing, a first internal contact element is mounted, which extends their cavities of this part in the axial direction. In the second part, as in the case, a second internal contract element is installed, also brought out of its cavity in the axial direction. The first and second contact elements perform the function of contact parts designed to pass current when the circuit is closed.

The male and female parts are equipped with first and second clamping elements, each of which is mounted on the rear side of these parts relative to the connected / disconnected sides. The clamping elements are made in the form of fittings. So, the second clamping element (related to the female part) has a shape that allows this element to perform the function of the flange of the male part.

The clamping parts are arranged so that the formed region between the first clamping element and the flange of the male part, as well as the region between the second pressing element and the flange of the female part, is designed to clamp the material through which the male and female parts are able to pass.

The design features of this connection is the presence of insulating elements covering the axially-derived contact elements.

Thus, the closest analogue to the claimed utility model is selected from patent document WO No. 2016099669 and is an electrical connector having, as common features with the claimed device, one button including the above elements.

The use of the above-described variant of the button from the description of WO No. 16099669 causes a series of reasons that impede the achievement of the technical result.

The low degree of convenience of installing push-button connections on clothing material is explained by the need to install male and female parts without insulating elements and electrical contacts. Thus, the analyzed device acquires its final form after installing insulating elements with electrical contacts in the cavity of the parts, when the pressing elements are already in the cavity of these parts.

The removal of the isolated electrical contacts in the axial direction from the button cavity increases the overall size of the device.

In addition, the removal of contact elements in the axial direction determines the creation of an unprotected electrical system due to the fact that such a system is located on top of the material.

The implementation of the clamping elements as separate shaped parts characterizes the device as complex.

The proposed utility model solves the technical problem of creating a device that expands the arsenal of tools for this purpose, which has the property of compactness while increasing reliability and ease of use.

The technical problem is solved in that the electrical push-button connection includes a male part that performs the function of a plug, and a female part that performs the function of a socket, in the body of the plug having a flange, a first contact element is installed, made in the form of a socket contact part connected to the end of the first current-carrying wires, in the housing of the socket having a flange, a second contact element is installed, made in the form of a pin contact part connected to the end of the second current-carrying wire, the first and Thoraya contact piece mounted for contact with the plug and socket connection providing flow of electric current, the first and second current wire withdrawn from the cavities of the respective housings; the plug housing connected to the third live wire forms the first outer contact element, and the socket housing connected to the fourth live wire forms the second outer contact element, while the plug and socket are equipped with corresponding clamping elements, each of which is mounted on the rear side of the corresponding the housing relative to the side of connection / disconnection of each specified housing so that each corresponding area formed between the first clamping element and the flange of the plug, as well as between the second clamping element and the flange of the socket, is designed to clamp the material through which the rear parts of these bodies are able to pass, the first clamping element is made in the form of a clamping washer, the second clamping element is made in the form of a clamping cap. The utility model has the following implementation aspects.

The housing of the plug is made in the form of a male sleeve, the pin contact part is made in the form of a spring contact element containing a tip with a compression spring isolated in the body of the specified sleeve of the plug using the first insulating washer installed in its groove, the first current-carrying wire is removed from the cavity of the female sleeve through a slot, longitudinal with respect to the axis of the sleeve, through which a third individual external current-carrying wire is also output, the end of the compression spring extending into the rear polo be covered by sleeve filled by pouring a silicone compound, is coupled with the end of the first current wire via solder connection.

The first insulating washer is made of fiberglass with a foil surface facing the cavity of the rear part of the male sleeve and connected to the end of the compression spring by a soldered connection.

The housing of the socket is made in the form of a female sleeve, the socket contact part is made of a female contact part made in the form of a sleeve with a shoulder insulated in the socket body using a second insulating washer installed in the groove of this sleeve, and the sleeve shoulder is located on the side of its rear part, the second current-carrying wire is withdrawn from the cavity of the enclosing sleeve through a slot, longitudinal with respect to the axis of the sleeve, through which the fourth current-carrying wire is also output, while the end of the second current-carrying wire beyond led into the cavity of the sleeve from the side of the collar and soldered to the inner surface of this sleeve, and the back of the cavity of the enclosing sleeve is filled with a fill of an organosilicon compound.

The second insulating washer is made of fiberglass with a foil surface facing the collar of the sleeve and connected to this collar using a solder joint.

The first and second current-carrying wire is designed to connect to a power source, the third and fourth current-carrying wire is designed to connect to a consumer.

The free end of each live wire is equipped with a split end.

In the groove made in the cavity of the enclosing sleeve, a spring ring is installed to provide spring contact between the plug and the socket when connecting / disconnecting.

The expansion of the arsenal of means for this purpose is realized by performing a button-fastener function of a detachable connection designed to pass current.

According to the purpose of the utility model, the current transmission is achieved by connecting the main parts of the button fastener, performing the function of a plug and socket without the need for an additional button, as in the closest analogue to patent document WO No. 1609999669.

The introduction into the button fastener of a second pair of current-carrying wires (except for the first and second current-carrying wires connected to contact parts), namely the third and fourth wires connected respectively to the plug and socket housing, leads to the formation of external contact elements and causes the creation of a closed electrical chains.

So, for current flow through a closed circuit, the first current-carrying wire connected to the contact part installed in the plug housing and the third current-carrying wire connected to the plug housing can be connected to the current source, and the second current-carrying wire connected to the contact part installed in the socket, and the fourth current-carrying wire connected to the housing of the socket, with the consumer. To create a closed electrical circuit, this option for connecting current-carrying wires with a source and a consumer is not the only one. The path for electric current can be provided by connecting the first and third current-carrying wires to the consumer, and the second and fourth current-carrying wires to the current source.

External and internal contact elements are installed insulated to allow electric current to flow and safe use of the product. In the example of the proposed device, it is indicated which elements perform the function of a dielectric.

Thus, the closure of the electrical circuit occurs when connecting the external and internal contact elements, namely the plug and socket, providing contact contact parts.

Therefore, the proposed electrical connector, made in the form of a familiar button designed for installation on the material, provides a short circuit of the electrical circuit when fastening, without creating any inconvenience when using.

As an electrical connector, the proposed device has not only ease of use, but also the compactness by eliminating the need for an additional button that works in conjunction with the existing button to create a closed circuit.

In a preferred embodiment of the proposed utility model, the plug housing can be made in the form of a male sleeve with a flange, and the socket housing in the form of a female sleeve with a flange. This option is caused by the generally accepted form of a button fastener, manufactured on various equipment using known technologies.

To improve the usability of the device leads to the implementation of external and internal contact elements composite. Thus, the presence of a conductive wire — a flexible connection element — in each contact element creates the prerequisites for the possibility of removing the wires from the cavity of the corresponding sleeve through a slot made in the cylindrical part of the male and female bushings. Moreover, each slot is structurally limited by the flange of the plug and socket housing, respectively, and for the convenience of removing the wires can be made open on one side. Based on the foregoing, when a push-button connection is installed on a material, current-carrying wires can go out without bends to the side of the plug and socket on the surface of the material sandwiched between the flange and the clamping element of the fastened button to be connected / disconnected. Consequently, live wires brought out through the side of the plug and socket are on the surface of the material. This technique leads to the convenience of using the button, as current-carrying wires are not in the area of application of force when connecting and disconnecting the main parts of the button, as in the known prototype device when removing contact elements in the axial direction. It should be noted that the implementation of the plug and socket in the form of a sleeve provides mutual rotation of these elements when connecting / disconnecting, therefore, the degree of freedom. This property ensures the reliability of the structure, as when turning the plug and socket, bending of the wires is excluded.

When equipping live wires with lugs, it becomes possible to create an electrical circuit using wires of the required length.

Based on the foregoing, it follows that the claimed utility model extends the range of well-known tools of the same purpose and has the property of compactness and is convenient to use.

These and other features of the proposed device are illustrated with the help of the drawing: the figure shows an exploded assembly of a push-button electrical connector and an electrical circuit using this connection.

The push-button connection contains two main parts: a male sleeve 1 with a flange 2 and a female sleeve 3 with a flange 2. To ensure spring connection / disconnection, a spring ring 4 is installed in the groove of the female sleeve.

To ensure electrical contact between bushings 1 and bushings 3 — as a plug housing and socket housing — are equipped with the corresponding elements: pin contact part 5 and socket contact part 6. These elements 5 and 6 are insulated in the cavity of each sleeve 1 and 3 with the appropriate an insulating washer 7 made of fiberglass with a foil surface and installed in a stepped groove (not indicated by the position) covering and covered the bushings 1 and 3.

For the formation of a closed electrical circuit that provides the flow of current, the push-button connection contains two pairs of insulated current-carrying wires 8.

The end of the first wire 8 of the first pair of the solder joint is attached to the spring contact element 5 (pin contact part), the end of the second wire 8 is connected to the cavity of the sleeve 6 (socket contact part) and connected to its inner surface by the solder joint. The spring contact element 5 is a metal tip with a compression spring (not indicated by positions).

Similarly, by solder connection, the wires of the second pair: the end of the third wire 8 is connected to the cavity of the male sleeve 1, the end of the fourth wire 8 is connected to the cavity of the female sleeve 3.

Thus, the connection of the sleeve 6 with the end of one live wire 8 and the connection of the spring contact element 5 with the end of the other live wire 8 form two internal contact elements, and the connection of the cavity of each sleeve 1 and 3 with the end of each live wire 8 of the second pair forms the outer contact elements .

To prevent axial displacement when axial forces are applied when the button is fastened / unfastened (in other words, when connecting / disconnecting the main parts of the button), the sleeve 6 is made with a collar 9 connected by a solder connection to the foil surface of the insulating washer 7 (installed in the cavity of the sleeve 3). At the same time, the spring contact element 5 is connected to the foil surface of the insulating washer 7 (installed in the cavity of the sleeve 1). The foil surface of each insulating washer 7 faces toward the rear of the bushings 1 and 3.

The implementation of the insulating washers 7 of fiberglass with a foil surface connected to the contact parts 5 and 6 (spring element and sleeve), provides the ability to make a solder connection necessary for fixing the spring element 5 and sleeve 6 as conductive elements.

In addition, to fix the insulating washers 7, the back of the cavity of the bushings 1 and 3 is filled with an organosilicon compound 10, which is an insulating element.

As indicated, the purpose of the button connection is performed when the main parts of the button — the plug and socket — are installed on the material, for example, on clothing material intended for heating / cooling or used as “smart clothes”.

Thus, when installing the plug and socket in a regular place, it is envisaged to remove live wires through the slot 11 (longitudinally directed relative to the axis of the bushings 1 and 3), made on the side surfaces of the rear part of the male sleeve 1 and the female sleeve 3. The slot 11 is open on one side and, on the other hand, it is limited by flange 2. The constructive implementation in each sleeve 1 and 3 of the location of the stepped groove, slot 11 and the choice of height of the insulating washer 7 is dictated by the need for optimal ohm output current wire 8 of the hubs 1 and 3 with no kinks that lead to wire rupture progressively data.

The main parts of the push-button connection must be assembled.

An example is the assembly of the main part of the electrical push-button connection, which is a plug.

A spring contact element 5 and a conductive wire 8 are connected by a soldered connection to the foil surface of the insulating washer 7 of the male sleeve 1. An insulating washer 7 with the indicated elements connected to it is connected to the stepped groove. The end of another current-carrying wire 8 is attached to the inner surface of the male sleeve 1 from the side of the insulating washer 7 by solder connection. The internal cavity of the male sleeve 1 from the side of the insulating washer 7 is filled with organosilicon compound 10, not reaching the edge of the sleeve. In this case, current-carrying wires exit the fill with compound 10.

Similarly, the second main part of the electrical connector is assembled - the socket. Moreover, an annular spring element 4 is installed in the groove of the enclosing sleeve 3.

Next, the prepared part of the plug is installed in a regular place - on the material (not indicated by the position) - so that the flange 2 of the male sleeve 1 fits snugly on the material at the installation site. The wires 8 coming from the spring element 5 and the male sleeve 1 are led out sideways from the cavity of this sleeve through the slot I. Then, a compression washer 12 is installed on the outer cylindrical surface of the rear part of the male sleeve 1. The cylindrical walls protruding above the pressure plate 12 are expanded, and on the flared part it is advisable to install a protective cover (not shown in the drawing).

The prepared part of the socket is also installed in a regular place so that the flange 2 of the female sleeve 3 fits snugly on the material at the installation site. The current-carrying wires 8, coming from the sleeve 6 and the female sleeve 3, are led out of the sleeve cavity 3 sideways through the slot 11. A clamping cover 13 is mounted on the outer cylindrical surface of the rear part of the female sleeve 3 and secured with a press fitting.

From the above it follows that the plug and socket are installed on the material in a complete assembly. In this case, current-carrying wires can be placed between the layers of material. This possibility provides a basis for the conclusion about the usability of the claimed utility model without the need for assembly at the installation site.

The bushings 1 and 3, the sleeve 6, the clamping elements 12 and 13 can be made of brass brand LS59-1.

To create a closed electrical circuit, the ends of current-carrying wires 8 can be equipped with detachable terminals 14, connected to current-carrying wires of an electric system having a current source 15 and a consumer 16. For example, when using this utility model on clothes with a heating function, electric batteries serve as a current source or batteries, and heating elements as a consumer. Thus, when the button is fastened by connecting its main parts - the plug and the socket, ensuring contact of the contact parts, there are all necessary elements for the current to flow through a closed electrical circuit. When the main parts of the button are disconnected, the electric circuit becomes open.

The use of a fastener button having an electrical connection function is not limited to installing clothes on a material, such use is indicated as one example of a possible use of the proposed utility model. The material of the products can be any artificial or natural materials, for example, leather, wood veneer, plastic, fabric, textile material such as Velcro (Velcro).

Summarizing the disclosure of the essence of the utility model, we should dwell on its advantages:

- reliability of use as an electrical connector due to the design, perceived as a familiar button-fastener;

- convenience of fastening / unfastening due to the removal of current-carrying wires sideways relative to the axial direction;

- adaptation to the installation location on the material due to the compactness as a snap button;

- adaptation to the installation site as an electrical connector by connecting the current-carrying wires of the plug to the source / consumer and the current-carrying wires of the socket to the consumer / source based on the convenience of organizing the electrical circuit in a particular product;

- ensuring a degree of freedom due to the mutual rotation of the main parts of the button fastener, leading to ease of use.
