Description

a jack connector

technical field

The present application relates to electrical connectors, in particular to a socket connector.

Background technique

In the field of electrical connection, there is a type of circular pin socket connector, and the pins are often not directly in hard contact with the inner hole of the jack, but contacts are installed in the inner hole of the jack. The contact piece is a kind of elastic structure, and the pin presses the contact piece when mating, so as to generate a long-term contact force between the pin and the inner hole wall of the socket, so as to ensure the durability of the electrical connection between the pin and the socket and reliability.

Among the contacts, there is a type of wire spring wire (that is, a metal wire with better elasticity). The socket that uses the wire spring wire as the contact is called a wire spring socket, and its full name is a single-leaf rotary hyperboloid wire spring socket. , because of its small insertion force, small contact resistance and high reliability, it is mainly used in connectors for various key equipment, such as aerospace, weaponry, medical equipment, automotive electronics testing, railway rolling stock, electronic communications, smart devices , Petroleum, chemical industry, exploration, etc., the application range is very wide. After the two ends of the wire spring wire are turned over from the hole of the inner sleeve around the wall of the inner sleeve, the two ends are respectively pressed through the front sleeve and the rear sleeve, so that the two ends of the wire spring wire are tightly matched to the inner sleeve and the outer sleeve (ie, the front sleeve). or the back sleeve); the middle section of the wire spring wire is a separable contact part, which is placed in the hole of the inner sleeve and can be separated or contacted with the pin; the overall shape of the wire spring contact is a cage-like cylindrical body.

Among the contacts, there is also a type of leaf spring, which is widely used in jack connectors because of its low resistance, high reliability, and low cost. A jack that uses a leaf spring as a contact is called a leaf spring jack, that is, a leaf spring jack connector. The leaf spring is integrally formed by a metal plate, and the shape is a cage-like cylindrical body, including two circular contact rings at both ends and grid bars connecting the two ends. The manufacturing process of the leaf spring is usually: (1) the metal plate is divided into a fence shape by removing material, and the two ends of the fence are connected by several pieces of fence bars; (2) if necessary, the two ends of the fence or the fence bars can be continued Reshaping; (3) rolling into a cage-shaped cylindrical body; (4) according to product requirements, its elastic effect can be further enhanced, such as bending and shrinking in the middle of the grid (such as "crown spring") or through a round contact at one end to surround The central axis is twisted into a helical curve shape relative to the other end (such as "torsion spring", "rotation spring"), so that each grid bar shrinks toward the axis in the middle, forming a structure with two ends large and the middle small.

The wire spring or leaf spring contact must provide elastic properties in terms of mechanical properties, and provide a durable contact pressure for the contact with the pin; in terms of electrical performance, the wire spring or leaf spring contact itself must complete the electrical conduction function. Therefore, the wire spring or leaf spring contact has two basic functions of providing elastic force and conducting electricity, and has high requirements on the comprehensive performance of the material. In the current electrical contact materials, when the mechanical properties of the material are good, the electrical conductivity is poor; when the electrical conductivity is good, the mechanical properties are poor. Wire spring or leaf spring contacts are mainly made of copper alloy materials, such as brass, phosphor bronze, beryllium copper, titanium copper and so on.

In the new energy industry, due to the large current, tens of amperes to hundreds of amperes are mainly used. Therefore, it is usually necessary to choose a contact material with good comprehensive performance, such as beryllium copper, but this material is expensive, mainly imported, and the delivery time is as long as several months. And there are also many deficiencies in the beryllium copper material of the prior art, for example: the electrical conductivity of beryllium copper (%IACS) is between 17%～65%, and there is still a big difference between the 100% electrical conductivity of pure copper, resulting in contact parts Its own heat is high; the normal use temperature of beryllium copper materials is generally below 150 degrees, when the temperature reaches a higher level, it is easy to cause the stress relaxation of the material to intensify, and gradually lose its elasticity; under the conditions of the material thickness and elastic deformation degree It is difficult to adjust the insertion force; beryllium copper is much more expensive than pure copper, and it takes a long time to purchase.

(first embodiment)

Fig. 1a shows a perspective view of the jack connector involved in the first embodiment of the present application. Fig. 1b shows a cross-sectional view along the axis of the socket connector involved in the first embodiment of the present application. Fig. 1c shows an exploded view of the jack connector involved in the first embodiment of the present application. Fig. 1d shows a perspective view of the contact piece and the pressure part involved in the first embodiment of the present application.

As shown in Figures 1a, 1b, 1c and 1d, the receptacle connector 01 involved in the first embodiment of the present application includes a receptacle sleeve 20, two inner ferrules 21, a cage-type cylindrical contact 22 and a pressure Section 23. The socket sleeve 20 further includes a cylindrical contact sleeve 20a. The cage-type cylindrical contact piece 22 is a single-section leaf spring, including two ring-shaped fixed contact parts 22a that are permanently in contact with the inner wall of the cylindrical contact sleeve 20a through fixed installation. The two fixed contact parts 22a are distributed in the contact both ends of piece 22. Between the two fixed contact parts 22a is connected a separable contact part 22b that can be separated or contacted with the pin. In this embodiment, 22b is implemented as a diagonal grid, that is, the projection of the grid on the axial section The central axis 24 of the contact 22 is inclined, and those skilled in the art can also use leaf spring contacts of other shapes and structures, such as traditional crown springs, and the projection of the grid strips on the axial section is parallel to the central axis of the contact. The contact piece 22 is installed in the cylindrical contact sleeve 20a. The two inner ferrules 21 are respectively placed in the two fixed contact parts 22a, and the fixed contact parts 22a are tightly fitted between the cylindrical contact sleeve 20a and the inner ferrule 21. Very good electrical contact can be achieved through the tight fit of the inner ferrule 21, the fixed contact portion 22a and the cylindrical contact sleeve 20a, rather than relying solely on the tension of the fixed contact portion 22a, thus increasing the stability and stability of the electrical contact. reliability. The pressure part 23 is an elastic body, the elastic body is a spring 23a, its cross section is circular, and its structure is helical.

Fig. 1e shows a perspective view of the non-circular cross-section spring involved in the first embodiment of the present application, Fig. 1f shows a perspective view of the shrapnel involved in the first embodiment of the present application, and Fig. 1g shows the first embodiment of the present application A perspective view of the multi-shrapnel connection involved in the method.

In another embodiment, the pressure part 231 may be implemented as a spring 231a with a polygonal cross section, as shown in FIG. 1e.

In yet another embodiment, the pressure part 232 is realized as an elastic body formed by a shrapnel 232a. As shown in FIG. 1f, its structure is non-helical.

When the pin is mated with the socket, electrical contact is made between the pin and the contact, and the contact pressure has a great influence on the contact resistance. In the traditional leaf spring socket, the contact pressure is provided by the spring force of the leaf spring contact itself; the current passes through the leaf spring contact to realize the electrical connection with the socket sleeve, and the leaf spring contact itself has to undertake the function of electrical conduction. Therefore, the leaf spring contact has two basic functions of providing elastic force and conducting electricity, and has high requirements on the comprehensive performance of the material. In the current electrical contact materials, when the mechanical properties of the material are good, the electrical conductivity is poor; when the electrical conductivity is good, the mechanical properties are poor. In the connector 01 involved in this embodiment, a part of the elastic function of the leaf spring contact 22 is peeled off, and the pressure part 23 is used to provide compensation; the leaf spring contact 22 mainly undertakes the conductive function, so the electrical conductivity can be selected. A material close to the 100% conductivity of pure copper, to achieve the purpose of improving performance, reducing costs, and improving supply chain security. Not using beryllium copper material is also beneficial to reduce the pollution of beryllium, a highly toxic element, to the environment. The pressure part 23 can also be made of high-temperature-resistant material, so as to increase the working temperature of the socket. Without changing the material thickness and deformation height of the leaf spring contact piece 22, by adjusting the pressure part 22, such as adjusting the elastic coefficient of the spring, the insertion and withdrawal force of the socket can be adjusted conveniently.

The fluid filled in the cavity is gas or liquid. At the same time, the socket sleeve 201 also leaves gaps at corresponding positions of the fluid inlet 235a and the fluid outlet 235b. During the plugging and unplugging process, the pressure is controlled by changing the amount of fluid in the cavity 235c, such as reducing the external pressure, which can increase the life of plugging and unplugging. If the pressure supply is cut off and the external pressure is supplied only in the mated state, the wear during the mating process can be greatly reduced, and the plugging life can be greatly extended. The use method and assembly sequence of this embodiment are consistent with those of the first embodiment. Those skilled in the art should understand that the existence of the fluid inlet 235a and the fluid outlet 235b is to input fluid when pressure needs to be provided, and to output fluid when no pressure needs to be provided. It can also be simplified by removing the two and maintaining fluid pressure at all times.
