Description

Technical Field

[0001] The utility model relates to the field of electric connectors, in particular to a large-current card-type floating cable connector. Background Art

[0002] In recent years, the entire automotive industry, computer communications industry, industrial control and other application fields have been continuously developing, and the entire connector industry has also been rapidly updating its products. Among them, cable-to-cable connectors have developed particularly rapidly, and the general development direction is towards small product size, large transmission current, easy installation, and stronger versatility.

[0003] The general cable-to-cable connection system requires two interoperable wire-end connectors. The cable needs to be riveted with the terminals of the cable connectors at both ends, and then assembled into the corresponding plastic housings, so that the connectors at both ends can play the role of transmitting current. In order to transmit large currents, the terminal volume is often relatively large, which leads to the increase in the size of the connector and the space occupied by the entire connection system. In addition, the existing cable-to-cable connectors generally require manual alignment of the connector ports on both sides before installation, which is not convenient for automatic installation.

[0004] At present, many of the existing high-current connectors on the market have the following disadvantages:

[0005] 1. Currently, flat terminals are mostly used in high-current connectors on the market. Due to the existence of connector matching tolerance, when the male and female connectors are matched, the terminal contact part is not necessarily centered. If the tolerance is too large, there will be a phenomenon of unilateral contact, which seriously affects the contact reliability of the product;

[0006] 2. The positions of the existing male and female connector ports are fixed and can only be inserted when the connector is well positioned, which affects installation efficiency and is not convenient for automated installation. Utility Model Content

[0007] In order to solve the above problems, the utility model proposes a large-current card-type floating cable connector, which solves the problem of low plug-in reliability of male and female ends of existing large-current connectors.

[0008] The main contents of the utility model include: a large current card-type floating cable connector, including: a male connector and a female connector that can be plugged and connected, the male connector includes: a male plastic body, a male panel for fixing the male plastic body, and a male terminal integrally formed with the male plastic body; the female connector includes: a female plastic body, a female panel for fixing the female plastic body, and a female terminal integrally formed with the female plastic body;

[0009] At least one male end positioning groove is provided at the mating end surface of the male end plastic body and the female end plastic body, and the same number of matching female end positioning columns are provided at the corresponding position of the female end plastic body, and the end of the female end positioning column is provided as a conical structure.

[0010] Preferably, a floating block is provided at the male connector and / or the female connector, and the floating block is detachably connected to the male connector and / or the female connector.

[0011] Preferably, a male terminal waist that is recessed inwards is provided at the middle outer circumference of the male terminal, and a male terminal step that matches the male terminal waist is provided at a corresponding position of the male terminal plastic body.

[0012] Preferably, a female terminal waist that is recessed inwards is provided at the middle outer circumference of the female terminal, and a female terminal step that matches the female terminal waist is provided at a corresponding position of the female terminal plastic body.

[0013] Preferably, a joint between the male terminal and the male cable is covered with a male heat shrink tube.

[0014] Preferably, a junction between the female terminal and the female cable is covered with a female heat shrink tube.

[0015] Preferably, the floating block is connected to the male connector and / or the female connector via a snap-fit ​​connection.

[0016] Preferably, the male terminal and the female terminal are both circular in cross-section along the radial direction.

[0017] The beneficial effects of the utility model are:

[0018] 1. When the male connector and the female connector are mated, there is no need for a good mating position. The two plastic bodies can be well used to insert the two connectors into the corresponding positions through the male end positioning groove and the female end positioning column, which is also convenient for automated installation design;

[0034] The technical solution protected by the utility model is described in detail below with reference to the accompanying drawings.

[0035] like Figure 1 As shown, a large current card-type floating cable connector includes: a male connector 1 and a female connector 2 that can be plugged and connected. When in use, the male connector 1 and the female connector 2 are plugged and connected to achieve current or signal connectivity.

[0036] like Figure 2-Figure 4As shown, the male connector 1 comprises: a male plastic body 11, a male panel 12 for fixing the male plastic body 11, and a male terminal 13 integrally formed with the male plastic body 11, wherein the male plastic body 11 and the male panel 12 are fixedly connected. The male terminal 13 is integrally injection molded with the male plastic body 11.

[0037] Further, such as Figure 5 As shown, a male terminal waist 131 that is recessed inward is provided at the middle outer circumference of the male terminal 13, and a male terminal step 112 that matches the male terminal waist 131 is provided at a corresponding position of the male terminal plastic body 11. Through the application of the step structure, after the male terminal 13 is molded in the male terminal plastic body 11, it is not easy to move radially, so that the male terminal 13 is more firmly fixed in the male terminal plastic body 11.

[0038] like Figure 6-Figure 8 As shown, the female connector 2 includes: a female plastic body 21, a female panel 22 for fixing the female plastic body 21, and a female terminal 23 integrally formed with the female plastic body 21; the female plastic body 21 and the female panel 22 are fixedly connected. The female terminal 23 is integrally injection molded with the female plastic body 21.

[0039] Further, such as Fig. 9 As shown, a female terminal waist 231 that is recessed inward is provided at the middle outer circumference of the female terminal 23, and a female terminal step 212 that matches the female terminal waist 231 is provided at a corresponding position of the female terminal plastic body 21. Through the application of the step structure, after the female terminal 23 is molded with the female terminal plastic body 21, it is not easy to move radially, so that the female terminal 23 is more firmly fixed in the female terminal plastic body 21.

[0040] like Figure 2 As shown, two male end positioning grooves 111 are provided at the mating end surfaces of the male end plastic body 11 and the female end plastic body 21. Figure 5 As shown, the same number of matching female end positioning columns 211 are arranged at the corresponding position of the female end plastic body 21, and the ends of the female end positioning columns 211 are arranged in a tapered structure. When the male end connector 1 and the female end connector 2 are mated, it is not necessary to have a good matching position. The male end connector 1 and the female end connector 2 can be well mated by relying on the cooperation between the male end positioning groove 111 and the female end positioning column 211.
