Description

male and female connector

technical field

The utility model relates to a male-female connector, in particular to a connector in the form of a male-female body.

Background technique

Connectors are important components for connecting circuits or signal connections between electronic components. For example, they can be used to connect separate wires, or connect separate printed circuit boards, or connect separate wires and printed circuit boards, so they have a wide range of applications It is used in various environments, such as computers, telecommunications, communications and data transmission, and even medical, industrial electronic measuring instruments, automobiles and other industries must use connectors.

In order to connect two separate electronic components to transmit electrical signals, each electronic component needs a female connector and a male connector respectively as a connection medium. Since the appearance and specifications of the female connector and the male connector are different, in the manufacturing process of the connector, it is necessary to open the mold separately to make the female connector and the male connector. It is not a small burden for the manufacturer of the connector. If it is necessary to open two sets of molds to make the female connector and the male connector each time in order to connect the electronic components with different interfaces, it will consume too much production. cost.

Please refer to FIG. 1, which is an existing electrical connector assembly 100, which includes a female connector 110 and a correspondingly matable male connector 120, wherein the female connector 110 includes a housing 111 and a housing 111 For the extended cable 112, the casing 111 is further formed with an accommodating portion 113, and a sleeve 114 is embedded in the accommodating portion 113, and the male connector 120 also includes a casing 121 and an extension extending from the casing 121. The cable 122 comes out, and the housing 121 also forms an accommodating portion 123, and a plug terminal 124 matching the sleeve 114 is embedded in the accommodating portion 123, so that the male connector 120 can be plugged in correspondingly. In the female connector 110 , the insertion terminal 124 of the male connector 120 and the sleeve 114 of the female connector 110 can be overlapped correspondingly for signal transmission.

However, when the above-mentioned electrical connector assembly 100 is assembled and connected, the male connector 120 must be inserted into the female connector 110 in the correct direction to realize the electrical connection, but in appearance, the insertion of the male connector 120 and the female connector 110 Both ends are round, so when the user distinguishes between the male connector 120 and the female connector 110, it must be based on the embedded plug-in terminal 124 or the sleeve 114. If the user ignores this, it will lead to Otherwise, manual adjustment is required to connect the male connector and the female connector, which makes the assembly process cumbersome.

Contents of the invention

According to the prior art disclosed above, due to the limitation of the shape of the male connector and the female connector, it is necessary to further distinguish and connect with each other according to the insertion terminal or sleeve embedded in it, while the male connector and the female connector The connectors need to set up a set of molds respectively, which increases the production cost. In view of this, the purpose of the present invention is to provide a male-female connector, which can successfully achieve electrical connection through the male-female body type, and can also reduce production costs.

In order to achieve the above object, the utility model provides a male-female connector, which includes a first sleeve, a second sleeve, and a connecting body connecting the first sleeve and the second sleeve, wherein the first The two ends of the sleeve are respectively formed with a first accommodating part and a first connection part, and the second sleeve is arranged along the side wall of the connecting body in the radial direction of the first sleeve, and one end is formed with a first Two accommodating parts, and the outer diameter of the second accommodating part is larger than the inner diameter of the first accommodating part.

According to a male-female connector disclosed by the utility model, its function is to connect the first sleeve and the second sleeve through the connecting body to form a whole. If the connecting body connects more sleeves, the male and female The connector has expansion functions and can be applied to a multi-conductor cable to accept cables from various conductors. Furthermore, since the inner diameter of the second accommodating portion is larger than the outer diameter of the first accommodating portion, when two identical male and female connectors are connected to each other, they can be socketed directly with the matching accommodating portion, There is no need to distinguish whether the mating ends are correct, and this fool-proof design mechanism can avoid polarity reverse connection caused by wrong mating of two identical connectors. In addition, this hermaphrodite connector only needs one set of molds to be applicable to various electronic devices. Compared with the prior art that requires two sets of molds, it only needs to open one set of molds, which greatly simplifies the structure and composition , It can also save the cost and time of mold opening.

The utility model will be described in detail below in conjunction with the accompanying drawings and specific embodiments, but not as a limitation of the utility model.
