Description

Technical Field

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

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

[0003] Among the contact pieces, there is a 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 piece is called leaf spring jack. The leaf spring is formed from a metal flat plate in one piece, and has a cylindrical shape of a circular cage, including fixed contact rings at both ends and bars connecting the two ends. The manufacturing process of the 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 a number of bars; (2) If necessary, the two ends of the fence or the bars can be further shaped; (3) rolled into a circular cage-like cylinder; (4) The elastic effect can be further enhanced according to product requirements, such as bending and waisting the bars in the middle (such as "crown spring") or twisting one end around the central axis relative to the other end into a spiral curve (such as "torsion spring"), so that each bar shrinks toward the axis in the middle, forming a structure with large ends and small middle. The crown springs, torsion springs, RADSOK, NETSOK, NEWSOK, etc. commonly known in the industry are all leaf spring types.

[0004] The two ends of the leaf spring contact are fixed contact rings. It is a very difficult problem to achieve reliable electrical contact between the leaf spring contact and the socket sleeve in a narrow space. Among the existing leaf spring sockets, there is a type of socket whose socket sleeve inner diameter is slightly larger than the diameter of the fixed contact ring when the joint is closed, so that the leaf spring contact is placed in the inner hole of the socket sleeve during assembly. After being placed, the fixed contact ring is in contact with the inner hole wall of the socket sleeve by relying on the tension of the leaf spring itself (see Figure 1a ), this type of jack is low in cost and has been widely used, especially in the field of small currents, but the contact effect is not good and the stability is also poor. The so-called "crown spring" jack in the industry belongs to this type of jack.

[0005] In order to ensure that the fixed contact part of the leaf spring is reliably connected to the socket sleeve, in the late 1980s, U.S. Patents No. 4657335 and No. 4734063 provided a structure designed with two outer sleeves and one inner sleeve. The fixed contact part of the leaf spring is turned 180 degrees outward around the inner sleeve and then tightly fitted between the inner and outer sleeves. This structure smoothly realizes the compression connection between the fixed contact part of the leaf spring and the socket sleeve (see Figure 1b ). Through more than 20 years of practical use, the reliability of the connection has been proven and it has been widely used in high current connection fields around the world. This structure jack is the RADSOK jack of the connector giant Amphenol. Some people in the industry commonly call this type of jack a "torsion spring" jack.

[0006] The fixed contact part is clamped between the inner and outer sleeves. This connection effect is good, but the cost is high because the fixed contact part of the inner and outer sleeves and the leaf spring needs to be flipped 180 degrees.

[0007] Faced with the increasingly urgent demand for high-current connectors with small size and low cost in emerging industries such as new energy vehicles, existing technologies are in urgent need of improvement and enhancement. Summary of the invention

[0008] In view of this, the object of the present application is to provide a jack connector and a processing method thereof that can achieve reliable electrical contact and is low in cost.

[0009] The first aspect of the present application relates to a jack connector, comprising: a jack sleeve, including a cylindrical contact sleeve; a round cage-type cylindrical contact piece, installed in the inner hole of the cylindrical contact sleeve, including a fixed contact ring fixedly contacted with the jack sleeve and a separable contact grid bar that can be separated or contacted with the pin, and the fixed contact ring and the jack sleeve are tightly closed to form a thin-walled cylindrical structure so that the fixed contact ring is tightly matched with the inner hole of the cylindrical contact sleeve.

[0010] In the jack connector involved in the present application, the inner hole of the cylindrical contact sleeve generates a radial load external pressure uniformly distributed in the circumferential direction on the fixed contact ring. Under the action of this force, the merged mouth of the fixed contact ring will be tightly closed to form an externally pressed thin-walled cylindrical structure. This structure has strong elastic stability, thereby achieving a tight fit between the fixed contact ring and the cylindrical contact sleeve to form a reliable electrical contact.

[0016] In the processing method involved in the present application, the leaf spring contact piece is made by stamping and rolling an elastic metal flat plate. After rolling, due to the internal stress, its merged mouth will open a little. When assembled into the inner hole of the jack sleeve, the inner hole of the cylindrical contact sleeve generates a radial load external pressure uniformly distributed along the circumferential direction on the fixed contact ring. Under the action of this force, the merged mouth of the fixed contact ring will be tightly closed to form an externally pressed thin-walled cylindrical structure. This structure has strong elastic stability, thereby achieving a tight fit between the fixed contact ring and the cylindrical contact sleeve to form a reliable electrical contact.

The outer diameter of the inner probe part is smaller than the inner diameter of the round cage-shaped cylindrical contact piece. The top end of the inner probe part has a claw that can be inserted into the gap of the separable contact grid bars, and the outer diameter of the outer push part is slightly smaller than the outer diameter of the round cage-shaped cylindrical contact piece when the combined mouth is closed; the round cage-shaped cylindrical contact piece is pushed into the inner hole of the cylindrical contact sleeve along the introduction sleeve by the push rod.

[0019] In addition, in the processing method involved in the present application, optionally, the round cage-type cylindrical contact piece is installed in the inner hole of the cylindrical contact sleeve, and the fixed contact ring is tightly closed to form a thin-walled cylindrical structure so that the fixed contact ring is tightly matched with the inner hole of the cylindrical contact sleeve, including: the inner diameter of the cylindrical contact sleeve is smaller than the outer diameter when the fixed contact ring is tightly closed; heating the cylindrical contact sleeve to above a first preset temperature; cooling the round cage-type cylindrical contact piece to below a second preset temperature; installing the round cage-type cylindrical contact piece in the inner hole of the cylindrical contact sleeve with a gap; and restoring to normal temperature.

DETAILED DESCRIPTION

[0053] Hereinafter, the preferred embodiments of the present application will be described in detail with reference to the accompanying drawings. In the following description, the same symbols are assigned to the same components, and repeated descriptions are omitted. In addition, the accompanying drawings are only schematic diagrams, and the ratio of the dimensions of the components or the shapes of the components may be different from the actual ones.

[0054] Figure 1a A schematic diagram of a prior art leaf spring in a socket sleeve is shown. Figure 1bThe structure diagram of the prior art RADSOK is shown.

[0055] like Figure 1a As shown, after the leaf spring contact piece of the prior art is installed into the socket sleeve, its merging opening is opened, and it contacts with the socket sleeve by utilizing its own elasticity.

[0056] like Figure 1b As shown, RADSOK has a complex structure, with inner and outer sleeves, and the fixed contact part of the leaf spring needs to be turned over and tightly fitted between the inner and outer sleeves.

[0057] The connector involved in the present application can be applicable to electrical connectors, such as pin and socket connectors applicable to leaf spring types such as crown springs, torsion springs, rotary springs, RADSOK, etc.

[0058] (First Embodiment)

[0059] Figure 2a A perspective view of a jack connector according to a first embodiment of the present application is shown. Figure 2b A cross-sectional view along the axis of the receptacle connector according to the first embodiment of the present application is shown. Figure 2c An exploded view of the jack connector according to the first embodiment of the present application is shown. Figure 2d A perspective view of the contact joint before being closed according to the first embodiment of the present application is shown. Figure 2e A perspective view of the contact joint according to the first embodiment of the present application after being closed is shown. Figure 2f A schematic diagram showing a thin-walled cylindrical structure formed by a contact member involved in the first embodiment of the present application is shown.

[0060] like Figure 2a , 2bAs shown in Figures 2 and 2c, the jack connector 01 involved in the first embodiment of the present application includes a jack sleeve 20 and a circular cage-shaped cylindrical contact 22. The jack sleeve 20 further includes a cylindrical contact sleeve 20a and an external connection portion 20b. The external connection portion 20b may have a connection method such as a crimping hole or a thread, so as to increase the adaptability of use. The circular cage-shaped cylindrical contact 22 is a single-section leaf spring, including two fixed contact rings 22a that are permanently in contact with the inner hole of the cylindrical contact sleeve 20a through fixed installation. The two fixed contact rings 22a are distributed at both ends of the circular cage-shaped cylindrical contact 22. A separable contact grid 22b that can be separated or contacted with the pin is connected between the two fixed contact rings 22a. In this embodiment, 22b is implemented as an inclined grid, that is, the projection of the grid on the axial section is inclined 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 projection on the axial section is parallel to the central axis of the contact. The round cage-shaped cylindrical contact member 22 is made by stamping and rolling an elastic metal flat plate. After rolling, due to the internal stress, its combined opening will open a little, such as Figure 2d The circular cage-shaped cylindrical contact member 22 is installed in the inner hole of the cylindrical contact sleeve 20a. The inner hole of the cylindrical contact sleeve 22 generates a radial load external pressure F evenly distributed along the circumferential direction on the fixed contact ring 22a. Under the action of this force, the combined opening of the fixed contact ring 22a will be tightly closed, as shown in FIG. Figure 2e , Figure 2f As shown, an externally pressed thin-walled cylindrical structure is formed, which has strong elastic stability, thereby achieving a tight fit between the fixed contact ring 22a and the cylindrical contact sleeve 20a, and forming a reliable electrical contact. Those skilled in the art should understand that the radial load external pressure F should be moderate. If it is too small, the tight fit is insufficient and the electrical contact effect is poor; if it is too large, the thin-walled cylindrical structure will become elastically unstable and the fixed contact ring 22a will collapse and sink.

[0061] Figure 2g The schematic diagram shows the use state of the jack connector involved in the first embodiment of the present application. The pin 21 can be inserted into the jack sleeve 20 to form an electrical contact with the round cage cylindrical contact piece 22.

[0062] Compared with the existing crown spring and RADSOK, the first embodiment of the present application has the following advantages:

[0063] 1. In terms of performance, the electrical contact between the fixed contact ring 22a and the inner hole of the socket sleeve 20 far exceeds that of the traditional crown spring socket and is also better than RADSOK. The reasons are: (1) The contact area of ​​the fixed contact ring 22a is larger than the sum of the areas of several small arc segments after the RADSOK leaf spring is flipped; (2) The overall circularity of the fixed contact ring 22a is better than the small arc segment of RADSOK, and the tight fit effect with the inner hole of the socket sleeve 20 is better.

[0064] Taking the jack with a pin specification of φ12mm as an example, using a contact piece (material thickness of 0.5mm, the outer diameter of the fixed contact ring 22a when closed is φ13.2mm), the comparison between the traditional crown spring jack and the first embodiment of the present application is as follows: (1) The inner diameter of the jack sleeve of the traditional crown spring jack is φ13.3mm (must be larger than φ13.2mm, and can be installed into the inner hole by hand); (2) The inner diameter of the jack sleeve 20 of the first embodiment of the present application is φ13.1mm (must be smaller than φ13.2mm to achieve the effect of tight fit with the fixed contact ring 22a, and can only be assembled with tooling). The specific comparison is shown in Table 1.

[0065] Table 1 Data comparison between the crown spring socket and the first embodiment of the present application

[0066]

[0067]

[0068] 2. In terms of cost, it is on par with the cost of traditional crown spring jacks and less than half of the cost of RADSOK.

[0069] 3. The outer diameter is smaller than that of RADSOK, which is conducive to the small-volume design of high-current connectors, saving costs and installation space. For example, the outer diameter of the RADSOK universal part with a φ12mm pin specification is φ18.2mm, and the outer diameter of the universal part made in the specific implementation of this application is φ15.0mm.

[0070] 4. Compared with RADSOK, the process is simpler, the performance of mass-produced products is more stable and consistent, and the production efficiency is higher.

[0073] like Figure 3a , Figure 3bAs shown, the second embodiment of the present application is an improvement on the first embodiment, and only the differences are described here, and the same parts still use the same reference numerals. The difference between the jack connector 02 involved in the second embodiment of the present application and the jack connector 01 involved in the first embodiment is that the jack connector 02 includes a jack sleeve 201, and the jack sleeve 201 includes a cylindrical contact sleeve 201a and an outer sleeve 201b. First, the round cage-shaped cylindrical contact piece 22 is installed in the inner hole of the outer sleeve 201b to form a universal part, and then the universal part is installed in the inner hole of the cylindrical contact sleeve 201a through interference fit. The cylindrical contact sleeve 201a has a blocking structure at the port that is plugged with the pin to prevent the round cage-shaped cylindrical contact piece 22 from moving axially. In this embodiment, the blocking structure is a step circle 201c.

The rivet compression port 202b has a smaller diameter than the round cage-shaped cylindrical contact 22 when the combined port is closed, so it can effectively prevent its axial movement and disengagement.
