Description

Technical Field

[0001] The utility model belongs to the field of connectors, and in particular relates to a slotted double-ended jack quick-change terminal structure. Background Art

[0002] The contact is the conductive part and core component of the electrical connector, which transmits the electrical signal to the corresponding components at the other end to achieve the transmission of the electrical signal. There are many types of contacts available, but the most commonly used type of terminal is the slotted structure.

[0003] Traditional slotted structure terminals are mainly connected to cables at one end and the other end is the working end. Only one end can provide electrical signal transmission, which is no longer suitable for current usage requirements. It is quite insufficient in meeting the requirements of transmitting large currents, achieving fast terminal replacement, and reliable contact. Utility Model Content

[0004] The utility model aims to provide a new structure for the existing slotted structure to solve the problem of contact reliability.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A slotted double-ended jack quick-change terminal structure includes a jack base, one end of the jack base is a first jack body, and the other end is a second jack body, the jack in the first jack body and the jack in the second jack body are not connected to each other,

[0007] Along the axis of the socket base, a plurality of split grooves are arranged on the wall surface of the first socket body, a third groove is arranged along the circumferential direction on the outer surface of the first socket body, and an elastic ring for limiting the deformation of the split groove is sleeved in the third groove.

[0008] In the above technical solution, a plurality of split grooves are arranged along the circumferential direction of the first jack body.

[0009] In the above technical solution, on the first jack body, a second groove is arranged along the circumferential direction at the tail end of the split groove.

[0010] In the above technical solution, a boss is provided along the circumferential direction on the outer surface between the first socket body and the second socket body.

[0011] In the above technical solution, there are at least two bosses, and a first groove is arranged between the two bosses along the circumferential direction.

[0012] In the above technical solution, inner grooves are respectively arranged in the first socket body and the second socket body along the circumferential direction of the inner wall, and ring springs are arranged in the inner grooves.

[0013] In the above technical solution, the elastic ring is a non-closed loop structure.

[0014] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:

[0015] The structure of the present application enables the jack body to have two kinds of extrusion forces, internal and external, so that the elastic sheet formed after the slotting can be tightly held on the connector pin, thereby achieving contact stability and meeting the requirements of high-performance transmission.

[0022] All features disclosed in this specification, or steps in all methods or processes disclosed, except mutually exclusive features and / or steps, can be combined in any manner.

[0023] Any feature disclosed in this specification (including any additional claims, abstract and drawings), unless otherwise stated, may be replaced by other equivalent or alternative features with similar purposes. That is, unless otherwise stated, each feature is only an example of a series of equivalent or similar features.

[0024] like Figure 1 , Figure 2 , Figure 3 As shown, the jack base has two ends, one end is a first jack body 1, and the other end is a second jack body 2. Coaxial jacks in opposite directions are respectively arranged in the first jack body 1 and the second jack body 2.

[0025] In this embodiment, the structure that is mainly improved is the first socket body 1. On the wall surface of the first socket body 1, a splitting groove 4 is provided along the axial direction, and a plurality of splitting grooves 4 are provided along the circumferential direction of the first socket body 1. The plurality of splitting grooves 4 divide the first socket body 1 into a plurality of spring sheet structures, so that the entire first socket body 1 becomes a multi-petal-shaped spring sheet structure that can expand radially after being received.

[0026] In order to constrain the first socket body 1 in the radial direction, a third groove 8 is provided on the outer surface of the first socket body 1 along the circumferential direction, and an elastic ring 3 is sleeved in the third groove 8. The elastic ring 3 is as shown in FIG. Figure 4 In order to have the best restraining ability, the third groove 8 is arranged at the end portion of the first jack body 1. The elastic ring 3 is an unclosed ring structure, so that the elastic ring 3 has a very good force-bearing structure.

[0027] In order to reduce the root shear force of the sheet structure formed by the first socket body 1, a second groove 7 is provided at the end position of the splitting groove 4 of the first socket body 1. The second groove 7 is an arc-shaped groove structure and is evenly distributed along the circumference of the first socket body 1. The second groove 7 can ensure that the splitting groove 4 has the maximum deformation on the first socket body 1.

[0028] Furthermore, in order to ensure the fixation and deformation amount of the terminal structure, two boss structures are provided along the circumferential direction on the portion between the first jack body 1 and the second jack body 2, and a first groove 6 is provided between the two boss structures.

[0029] In this embodiment, inner grooves are provided in the circumferential direction of the jacks of the first jack body 1 and the second jack body 2, and ring springs 9 are provided in the inner grooves. When the terminal structure is not connected, the ring springs 9 are in a floating state.

[0030] When the first jack body 1 is connected to the pin of the opposite jack, the pin passes through the ring spring 9, and the ring spring 9 expands radially due to the extrusion force of the pin, thereby squeezing the first jack body 1, and the first jack body 1 expands radially. The elastic ring 3 at the end of the first jack body 1 constrains the expansion of the first jack body 1, so that the first jack body 1 is evenly closed toward the axis. When the first jack body 1 is completely connected to the pin of the opposite end, it is constrained by the other side's pin jack. When the pin comes into contact with the ring spring 9, the ring spring 9 in the inner groove is evenly expanded along the vertical direction of the axis toward the inner wall of the first jack body 1 under the action of external force, and the ring spring 9 and the inner wall of the first jack body 1 have multiple points of elastic contact, and under the tightening action of the elastic ring 3, a certain positive pressure is maintained. At the same time, in the second jack body 2, when multiple ring springs 9 are connected to the pin, the ring spring 9 and the inner wall of the second jack body 2 have multiple points of elastic contact, generating a reverse elastic force on the pin, forming a certain positive pressure. At this time, both ends of the jack base can generate appropriate positive pressure to ensure stable operation while achieving efficient transmission of electrical signals.

[0031] In order to ensure reliable assembly of the terminal structure, a positioning groove 10 is provided on the surface of the second jack body 2 for positioning during the connection process.

[0032] The present invention is not limited to the above-mentioned specific implementation modes, but extends to any new features or any new combination disclosed in this specification, as well as any new method or process steps or any new combination disclosed.
