Description

Technical Field

[0001] The present application relates to an electrical connector, and in particular to a jack connector. Background Art

[0002] In the field of electrical connections, there is a type of circular pin-and-socket connector. The pins often do not make direct, hard contact with the inner hole of the socket. Instead, a contact piece is installed in the inner hole of the socket. The contact piece is an elastic structure. When plugged in, the pin presses against the contact piece to generate a permanent contact force between the pin and the inner wall of the socket, thereby ensuring the durability and reliability of the electrical connection between the pin and the socket.

[0003] Among contact components, one type is spring wire (a metal wire with good elasticity). Sockets using spring wire as contact are called spring jacks, or single-leaf rotary hyperboloid spring jacks. Due to their low insertion and removal force, low contact resistance, and high reliability, they are primarily used in connectors for a wide range of critical equipment, including aerospace, weaponry, medical equipment, automotive electronic testing, railway rolling stock, electronic communications, intelligent devices, petroleum, chemical engineering, and exploration. The ends of the spring wire are twisted through the inner sleeve's hole, around the inner sleeve's wall, and then press-fitted through the front and rear sleeves, respectively, so that the ends fit tightly between the inner and outer sleeves (i.e., the front or rear sleeves). The middle section of the spring wire is the separable contact portion, located within the inner sleeve's hole, allowing it to separate or contact the pin. The overall shape of the spring contact is a cylindrical, cage-like structure.

[0004] Among the contact parts, there is another type of leaf spring, which is widely used in jack connectors due to its low resistance, high reliability and low cost. The jack using leaf spring as the contact part is called leaf spring jack, that is, leaf spring jack connector. The leaf spring is formed from a metal flat plate in one piece, and its appearance is a circular cage-like cylindrical body, including circular contact rings at both ends and bars connecting the two ends. The manufacturing process of leaf spring is usually as follows: (1) The metal flat plate is divided into a fence shape by removing material, and the two ends of the fence are connected by several bars; (2) If necessary, the two ends of the fence or the bars can be further shaped; (3) It is rolled into a circular cage-like cylindrical body; (4) Its elastic effect can be further enhanced according to product requirements, such as bending and waisting the middle of the bar (such as "crown spring") or twisting it into a spiral curve relative to the other end by making one end contact around the central axis (such as "torsion spring" or "rotation spring"), so that each bar shrinks toward the axis in the middle, forming a structure with large ends and small middle.

[0005] Wire or leaf spring contacts must mechanically provide elasticity, maintaining consistent contact pressure with the pins. Electrically, they must also conduct electricity. Therefore, they fulfill two fundamental functions: providing elasticity and conducting electricity, placing high demands on the overall performance of the material. Among current electrical contact materials, some offer excellent mechanical properties but poor electrical conductivity, while others offer excellent electrical conductivity but poor mechanical properties. Wire or leaf spring contacts are primarily made of copper alloys, such as brass, phosphor copper, beryllium copper, and titanium copper.

[0006] In the new energy industry, due to the large current, which ranges from tens to hundreds of amperes, it is usually necessary to select contact materials with good comprehensive performance, such as beryllium copper. However, this material is expensive, mainly imported, and has a delivery time of several months. In addition, the existing beryllium copper material also has many shortcomings. For example, the conductivity (% IACS) of beryllium copper is between 17% and 65%, which is still very different from the 100% conductivity of pure copper, resulting in high heat generation of the contact itself; the normal operating temperature of beryllium copper material is generally below 150 degrees. When the temperature reaches higher, it is easy to cause the stress relaxation of the material to intensify and gradually lose its elasticity; under the conditions of fixed material thickness and elastic deformation, it is difficult to adjust the insertion and extraction force; compared with pure copper, beryllium copper material is much more expensive and takes a long time to purchase. Summary of the Invention

[0007] In view of this, the purpose of the present application is to separate the structure of the contact member that provides the elastic function from the structure that provides the conductive function, and to provide a jack connector that can improve both the conductivity and the plugging and unplugging elasticity.

[0008] The present application relates to a jack connector, comprising: a jack sleeve, including a cylindrical contact sleeve; a circular cage-shaped cylindrical contact piece, made of a high-conductivity material, installed in the cylindrical contact sleeve, and having a wire spring or leaf spring structure, comprising a fixed contact portion electrically connected to the cylindrical contact sleeve and a separable contact portion that can be separated from or in contact with a pin; a pressure portion corresponding to the separable contact portion, wherein the corresponding pressure portion can wrap the separable contact portion, or can provide corresponding pressure in the form of a point or line; the pressure portion is installed between the circular cage-shaped cylindrical contact piece and the cylindrical contact sleeve, and provides external pressure when the pin contacts the circular cage-shaped cylindrical contact piece; an inner ring is located between the fixed contact portion and the cylindrical contact sleeve, and serves to reinforce and enhance the electrical contact. The circular cage-type cylindrical contact piece is composed of a wire spring or a leaf spring, which is fixed on an inner ring, and a corresponding pressure portion is provided between the inner ring and the wire spring or leaf spring; the circular cage-type cylindrical contact piece includes an inner sleeve and a wire spring or leaf spring fixed thereon, the portion of the wire spring or leaf spring in the inner sleeve constituting a separable contact portion, and the portions folded outward at both ends of the inner sleeve constituting fixed contact portions, and a corresponding pressure portion is provided between the inner sleeve and the wire spring or leaf spring; the corresponding pressure portion may wrap around the separable contact portion, or may provide corresponding pressure in the form of a point or line.

[0009] In the jack connector disclosed herein, a cylindrical cage contact electrically connects to a cylindrical contact sleeve to form a current path, while a pressure portion wrapped around the contact sleeve provides external pressure, allowing the cylindrical cage contact to partially or completely eliminate its function of providing spring force. High-conductivity materials, such as pure copper, can be used to improve the conductivity of the wire or leaf spring contacts and significantly reduce heat generated by the contacts themselves. Furthermore, a dedicated pressure portion provides external pressure, which is converted into the required contact pressure by the cylindrical cage contact when the pins are engaged. High-temperature-resistant materials can be used to increase the operating temperature of the jack.

[0010] In addition, in the jack connector involved in the present application, the pressure portion may optionally include an elastic body, a non-elastic body, or a combination of the two. The non-elastic body includes a pressure block, a slider, and other structures that can facilitate pressurization or decompression.

[0011] In addition, in the jack connector involved in the present application, optionally, the elastic body is any one of a spring or a spring sheet, and can also be an elastic body composed of multiple spring sheets connected by connecting sheets.

[0012] In the jack connector involved in the present application, a spring or a spring is used as an elastic body to provide contact elasticity of the contact piece, which is low-cost and simple and convenient to implement.

[0013] In addition, in the jack connector involved in the present application, optionally, the elastomer is made of a polymer material.

[0014] In addition, in the jack connector involved in the present application, optionally, the polymer material is any one of silicone, rubber or plastic materials, or can be a polymer material mixed with silicone, rubber or plastic materials.

[0015] In addition, in the jack connector involved in the present application, optionally, the pressure portion includes a fluid pressure bag, and the fluid pressure bag includes a cavity and a fluid filling the cavity.

[0016] In addition, in the jack connector involved in the present application, optionally, the fluid pressure package further includes a fluid inlet and outlet provided on the cavity, and the inlet and outlet can be a fluid inlet and a fluid outlet, or a fluid inlet and a fluid outlet.

[0017] In the jack connector involved in the present application, a fluid inlet and a fluid outlet are provided on the cavity. When external pressure is required, for example, after the pin has been fully inserted into the jack, fluid is filled in through the fluid inlet to generate external pressure. During the insertion or removal of the pin, in order to reduce the wear between the contact and the pin during the insertion or removal, the fluid should be released through the fluid outlet before the insertion or removal action, thereby reducing or removing the external pressure. This can facilitate insertion and removal while reducing wear and extending the service life.

[0018] In addition, in the jack connector involved in the present application, optionally, the pressure portion includes a pressure ring formed by one or more permanent magnet arc-shaped ring pieces connected end to end with different polarity.

[0019] In the jack connector involved in this application, a pressure ring is formed by a permanent magnet arc ring piece. On the one hand, external pressure can be easily generated by magnetism. On the other hand, the pressure of the permanent magnet can be changed by an external magnetic field, thereby forming different external pressures during plugging and unplugging and during stable contact.

[0020] In addition, in the jack connector involved in the present application, optionally, the jack sleeve further includes an external connection portion, which is connected to one end side of the cylindrical contact sleeve.

[0021] Furthermore, in the jack connector of the present application, the cylindrical cage contact can be a multi-section or multi-leaf spring. The cylindrical cage contact can be used in combination of more than one, or can be a cylindrical cage contact including at least two separable contact portions.

[0022] In the leaf spring jack connector involved in the present application, it can be provided with multiple sections or multiple leaf springs as required to increase the adaptability of use.

[0023] Compared with the prior art, the present application has not limited to the following beneficial effects: through the structural design of the pressure part, the component functions of the original product are changed, the conductive performance is enhanced, the cost of the product is reduced, the demand for high-performance materials is reduced, and the service life of the product is extended; through the design of the fluid pressure bag, the wear between the contact parts and the pins during plugging and unplugging is reduced, thereby extending the service life; through the design of the pressure ring, the contact stability is enhanced; through the design of the external connection part, the connection and use of the jack connector is facilitated to meet the requirements of different performance.

[0078] Hereinafter, preferred embodiments of the present application will be described in detail with reference to the accompanying drawings. In the following description, identical components are assigned identical reference numerals and repeated descriptions are omitted. In addition, the accompanying drawings are merely schematic diagrams, and the ratios of the dimensions of the components or the shapes of the components may differ from the actual ones.

[0079] The connector involved in the present application can be applicable to electrical connectors, such as pin and socket connectors applicable to wire spring types, crown springs, torsion springs, rotary springs, RADSOK and other leaf spring types.

[0080] (First embodiment)

[0081] Figure 1a A perspective view of a receptacle connector according to a first embodiment of the present application is shown. Figure 1b A cross-sectional view along the axis of the receptacle connector according to the first embodiment of the present application is shown. Figure 1c An exploded view of the receptacle connector according to the first embodiment of the present application is shown. Figure 1d A perspective view showing a contact and a pressure portion according to a first embodiment of the present application is shown.

[0082] like Figure 1a 、 1bAs shown in Figures 1c and 1d, the jack connector 01 according to the first embodiment of the present application includes a jack sleeve 20, two inner ferrules 21, a cage-shaped cylindrical contact 22, and a pressure portion 23. The jack sleeve 20 further includes a cylindrical contact sleeve 20a. The cage-shaped cylindrical contact 22 is a single-section leaf spring comprising two annular fixed contact portions 22a that are permanently in contact with the inner wall of the cylindrical contact sleeve 20a through a fixed installation. These two fixed contact portions 22a are located at both ends of the contact 22. A separable contact portion 22b, which can be separated from or in contact with the pin, is connected between these two fixed contact portions 22a. In this embodiment, 22b is implemented as an inclined grid bar, i.e., the projection of the grid bar on the axial cross-section is inclined with respect to the central axis 24 of the contact 22. Those skilled in the art may also use leaf spring contacts of other shapes and structures, such as a traditional crown spring, whose grid bar projection on the axial cross-section is parallel to the central axis of the contact. The contact 22 is mounted within the cylindrical contact sleeve 20a. The two inner ferrules 21 are respectively placed within the two fixed contact portions 22a, which are tightly fitted between the cylindrical contact sleeve 20a and the inner ferrules 21. The tight fit between the inner ferrules 21, the fixed contact portions 22a, and the cylindrical contact sleeve 20a enables excellent electrical contact, rather than relying solely on the tension of the fixed contact portions 22a. This increases the stability and reliability of the electrical contact. The pressure portion 23 is an elastic body, a spring 23a, with a circular cross-section and a spiral structure.

[0083] Figure 1e A perspective view of a spring with a non-circular cross section according to the first embodiment of the present application is shown. Figure 1f FIG1 shows a perspective view of a spring piece according to the first embodiment of the present application. Figure 1g A three-dimensional diagram of a multi-spring connection according to the first embodiment of the present application is shown.

[0084] In another embodiment, the pressure portion 231 can be implemented as a spring 231a with a polygonal cross section, such as Figure 1e shown.

[0085] In another embodiment, the pressure portion 232 is implemented as an elastic body formed by a spring 232a, such as Figure 1f As shown, its structure is non-spiral, and in this embodiment it is realized as a C-shaped ring structure. Those skilled in the art should understand that the pressure portion can also be realized as follows Figure 1g The 233 shown is formed by a plurality of spring pieces 233a. In order to connect the plurality of spring pieces into one body to form an elastic body, a connecting piece 233b may be further included. The connecting piece 233b connects two adjacent spring pieces 233a and may be formed by stamping and rolling a sheet metal into a whole.

[0086] The assembly sequence of the product is as follows: first assemble the pressure part 23 with the round cage cylindrical contact piece 22, as shown in the following figure: Figure 1dAs shown, they are then installed together into the inner hole of the jack sleeve 20 without the external connection part, and finally the inner rings 21 are assembled at both ends, and the leaf spring jack connector is assembled.

[0087] When a pin is mated with a socket, electrical contact is established between the pin and the contact, and contact pressure significantly impacts contact resistance. In traditional leaf spring sockets, contact pressure is provided by the spring force of the leaf spring contact itself. Current flows through the leaf spring contact, establishing an electrical connection with the socket sleeve, and the leaf spring contact itself must perform the electrical conduction function. Therefore, the leaf spring contact fulfills two fundamental functions: providing spring force and conducting electricity, placing high demands on the overall performance of the material. Current electrical contact materials often exhibit excellent mechanical properties but poor electrical conductivity, or vice versa. In connector 01 of this embodiment, the spring force function of leaf spring contact 22 is removed, with pressure portion 23 providing the compensation function. This allows leaf spring contact 22 to primarily perform the electrical conduction function. This allows the use of a material with a conductivity close to 100% that of pure copper, achieving improved performance, reduced costs, and enhanced supply chain security. Eliminating the use of beryllium copper also helps mitigate environmental pollution from this highly toxic element. The pressure portion 23 can also be made of a high-temperature resistant material to increase the operating temperature of the jack. Without changing the thickness or deformation height of the leaf spring contact 22, the insertion and removal force of the jack can be easily adjusted by adjusting the pressure portion 22, such as adjusting the elastic coefficient of the spring.

[0088] (Second embodiment)

[0089] Figure 2a FIG2 shows an exploded view of a jack connector according to a second embodiment of the present application. Figure 2b A perspective view showing a contact and a pressure portion according to a second embodiment of the present application is shown. Figure 2c A perspective view of an O-ring silicone elastomer according to a second embodiment of the present application is shown.

[0090] like Figure 2a and 2b As shown, the second embodiment of the present application is a variation of the first embodiment, the difference being that the pressure portion 234 of the connector 02 is implemented as an elastic body formed of a polymer material. In this embodiment, the pressure portion 234 is a silicone elastic body 234a. Figure 2a As shown, the silicone elastic body 234a is a cylindrical ring body, and other elastic structures known to those skilled in the art can also be used, such as an O-ring (O-Ring), as shown in Figure 2C. The pressure portion 234 can also be implemented as an elastic body such as rubber or plastic.

[0091] (Third embodiment)

[0092] Figure 3aA perspective view of a receptacle connector according to a third embodiment of the present application is shown. Figure 3b A cross-sectional view along the axis of a receptacle connector according to a third embodiment of the present application is shown. Figure 3c An exploded view of a receptacle connector according to a third embodiment of the present application is shown. Figure 3d A perspective view showing a contact and a pressure portion according to a third embodiment of the present application is shown.

[0093] like Figure 3a 、 3b As shown in Figures 3c and 3d, the third embodiment of the present application is a variation of the first embodiment. The difference lies in that the pressure portion 235 of the connector 03 is implemented as a pressure pack structure, comprising a fluid inlet 235a, a fluid outlet 235b, and a cavity 235c. The fluid filling the cavity can be gas or liquid. The jack sleeve 201 also has notches at the corresponding locations of the fluid inlet 235a and fluid outlet 235b. During the plugging and unplugging process, the pressure can be controlled by varying the amount of fluid in the cavity 235c, for example by reducing the external pressure, thereby improving plugging and unplugging life. If the pressure supply is cut off and external pressure is applied only when the connector is plugged in, wear during plugging and unplugging can be significantly reduced, significantly extending plugging and unplugging life. The usage and assembly sequence of this embodiment are consistent with the first embodiment. Those skilled in the art will understand that the fluid inlet 235a and fluid outlet 235b exist to allow fluid input when pressure is required and to output fluid when pressure is not. Alternatively, the fluid inlet 235a and fluid outlet 235b can be removed to maintain constant fluid pressure.

[0094] (Fourth embodiment)

[0095] Figure 4a A cross-sectional view along the axis of a receptacle connector according to a fourth embodiment of the present application is shown. Figure 4b An exploded view of a receptacle connector according to a fourth embodiment of the present application is shown. Figure 4c A perspective view showing a contact and a pressure portion according to a fourth embodiment of the present application is shown.

[0096] like Figure 4a 、 4bAs shown in Figures 4 and 4c, the fourth embodiment of the present application is a variation of the first embodiment, differing in that the pressure portion 236 of the connector 04 is a pressure ring formed by two permanent magnet arcuate ring pieces 236a connected end to end with opposite polarity. In the jack connector 04 involved in this embodiment, the permanent magnet arcuate ring piece 236a forms a pressure ring, which can generate pressure by itself through magnetism. The pressure of the permanent magnet arcuate ring piece 236a can also be changed by an external magnetic field (not shown), thereby achieving different contact pressures during insertion and removal and during stable contact. The two arcuate ring pieces 236a in this embodiment are exemplary, and those skilled in the art may provide more arcuate ring pieces as needed.

[0097] (Fifth embodiment)

[0098] Figure 5a A cross-sectional view along the axis of a receptacle connector according to a fifth embodiment of the present application is shown. Figure 5b An exploded view of a receptacle connector according to a fifth embodiment of the present application is shown. Figure 5c A perspective view showing a contact and a pressure portion according to a fifth embodiment of the present application is shown.

[0099] like Figure 5a 、 5b As shown in Figures 5 and 5c, the fifth embodiment of the present application is a variation of the first embodiment. The difference lies in that the circular cage-shaped cylindrical contact member 221 of the connector 05 is a two-section leaf spring, comprising three fixed contact portions 221a and two separable contact portions 221b. The separable contact portions 221b are each wrapped with a pressure portion 23. The two-section leaf spring in this embodiment is exemplary; those skilled in the art may utilize a leaf spring with more than two sections as needed.

[0100] (Sixth embodiment)

[0101] Figure 6a A cross-sectional view along the axis of a receptacle connector according to a sixth embodiment of the present application is shown. Figure 6b An exploded view of a receptacle connector according to a sixth embodiment of the present application is shown. Figure 6c A perspective view showing a contact and a pressure portion according to a sixth embodiment of the present application is shown.

[0102] like Figure 6a 、 6b As shown in Figures 6 and 6c, the sixth embodiment of the present application is a variation of the first embodiment. The difference is that the connector 06 uses two cylindrical cage-shaped contacts 22, each of which is a single-section leaf spring. The separable contact portion of each contact 22 is respectively wrapped by a pressure portion 23.

[0103] (Seventh embodiment)

[0104] Figure 7A cross-sectional view along the axis of a receptacle connector according to a seventh embodiment of the present application is shown.

[0105] like Figure 7 As shown, the seventh embodiment of the present application is a variation of the first embodiment, the difference being that the connector 07 uses a jack sleeve 201, which, in addition to the cylindrical contact sleeve 201a, also includes an external connection portion 201b, which may have a wire hole or a threaded connection method.

[0106] (Eighth Embodiment)

[0107] Figure 8a A cross-sectional view along the axis of a receptacle connector according to an eighth embodiment of the present application is shown. Figure 8b A cross-sectional view along the axis of a contact and a pressure portion according to an eighth embodiment of the present application is shown. Figure 8c A perspective view showing a contact and a pressure portion according to an eighth embodiment of the present application is shown. Figure 8d An exploded view of a contact and a pressure portion according to an eighth embodiment of the present application is shown. Figure 8e An assembly diagram of a receptacle connector according to an eighth embodiment of the present application is shown.

[0108] like Figure 8a 、 8b As shown in Figures 8c and 8d, this embodiment is a variation of the first embodiment. The difference lies in that connector 08 utilizes a circular cage-shaped cylindrical contact 222, which is a wire spring structure and further includes a fixed contact portion 222a and a separable contact portion 222b. The circular cage-shaped cylindrical contact 222 comprises an inner sleeve 222c and a spring wire 222d wound thereon. The portion of the spring wire 222d within the inner sleeve 222c forms the separable contact portion 222b, while the outwardly folded portions at both ends of the inner sleeve 222c form the fixed contact portion 222a. The pressure portion 23 is mounted between the inner wall of the inner sleeve 222c and the spring wire 222d.

[0109] The overall assembly process sequence is as follows: first install the pressure portion 23 into the inner sleeve 222c, then wind the wire spring 222d around the inner hole of the inner sleeve 222c, and then turn over the two ends of the wire spring 222d from the hole of the inner sleeve 222c around the wall of the inner sleeve 222c and fit toward the outer arc surface of the inner sleeve 222c, as shown in FIG. Figure 8c shown.

[0110] The jack sleeve 202 of this embodiment includes a cylindrical contact sleeve 202a and an external connection portion 202b. The external connection portion 202b may have a wire hole or a threaded connection method. The cylindrical contact sleeve 202a is divided into two parts, one of which is connected to the outer sleeve 202a. Figure 8b 、 8cThe parts shown are assembled and then merged with another part along axis 24, as shown in FIG. Figure 8e shown.

[0111] The connector 08 of this embodiment builds upon the traditional wire-spring connector structure with the addition of a pressure portion 23, mounted between the spring wire 222d and the jack sleeve 202. The spring wire 222d's elasticity is partially removed, allowing the pressure portion 23 to compensate. The spring wire 222d primarily performs the electrical conductivity function, allowing the use of a material with a conductivity close to 100% that of pure copper. This improves performance, reduces costs, and enhances supply chain security.

[0112] The contact member 222 of this embodiment can be combined with the second embodiment, the third embodiment, and the fourth embodiment, and use a pressure portion made of a polymer material, a fluid pressure bag, or a permanent magnetic material, respectively.

[0113] (Ninth embodiment)

[0114] Figure 9a A cross-sectional view along the axis of a receptacle connector according to a ninth embodiment of the present application is shown. Figure 9b A perspective view showing a contact piece and a pressure portion according to a ninth embodiment of the present application. Figure 9c An exploded view of a receptacle connector according to a ninth embodiment of the present application is shown.

[0115] like Figure 9a 、 9b As shown in FIG9c, this embodiment is a variation of the first embodiment, and the difference is that the connector 09 uses a circular cage-type cylindrical contact 223, including a fixed contact portion 223a and a separable contact portion 223b. The circular cage-type cylindrical contact 223 includes an inner sleeve 223c and a RADSOK leaf spring 223d. The portion of the RADSOK leaf spring 223d in the inner sleeve 223c constitutes the separable contact portion 223b, and the portions folded outward at both ends of the inner sleeve 223c constitute the fixed contact portion 223a. The pressure portion 23 is installed between the inner wall of the inner sleeve 223c and the RADSOK leaf spring 223d. In addition, the jack sleeve 203 is also different, and is composed of two symmetrical parts, such as Figure 9a shown.

[0116] The overall assembly sequence is as follows: (1) The circled RADSOK leaf spring 223d is installed into the inner hole of the inner sleeve 223c; (2) The outer bar (i.e., the fixed contact portion 223a) on one end of the RADSOK leaf spring 223d is turned 180 degrees toward the outside of the inner sleeve 223c and fixed with one of the socket sleeves 203; (3) The other end of the RADSOK leaf spring 223d is twisted around the center axis 24 relative to the fixed end of the leaf spring 223d; (4) The outer bar (i.e., the fixed contact portion 223a) on the unfixed end of the RADSOK leaf spring 223d is turned 180 degrees toward the outside of the inner sleeve 223c and fixed with the other socket sleeve 203.

[0117] The connector 09 involved in this embodiment is based on the traditional RADSOK connector structure, and a pressure portion 23 is added, which is installed between the RADSOK leaf spring 223d and the jack sleeve 203.

[0118] The above description is merely a preferred embodiment of the present application, and is a further detailed description of the present application in conjunction with specific preferred implementation methods. The specific implementation of the present application should not be considered to be limited to these descriptions. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present application shall be included in the scope of protection of the present application.
