Technical Field

The utility model relates to a contact.

Background

The splicing structure in the prior art mainly has two types: the chip type plug-in structure comprises a chip type jack contact element 101 and a chip type pin contact element 102 which are mutually plugged, the chip type jack contact element 101 comprises two first elastic arms 1011 which are oppositely arranged, the chip type pin contact element 102 is inserted into a channel formed by the two first elastic arms 1011 during use, and the chip type pin contact element 102 is in contact with the two first elastic arms 1011 to realize electric signal communication. The circular plug-in structure is shown in fig. 3 and 4, and includes a circular socket contact 103 and a circular pin contact 104, which are inserted into each other, the circular socket contact 103 includes a plurality of pairs of second elastic arms 1031 arranged oppositely, when in use, the circular pin contact 104 is inserted into a channel formed by the plurality of pairs of second elastic arms 1031, and the circular pin contact 104 is in contact with each second elastic arm 1031 to realize electrical signal communication.

Ideally, after the pin contact (including the chip pin contact 102 and the circular pin contact 104) is inserted into the socket contact (including the chip socket contact 101 and the circular socket contact 103), the pin contact makes good contact with each spring arm, so that electrical signal communication is realized. However, in practical use, it is found that the pin contact and the socket contact must be aligned and then inserted into each other, as shown in fig. 5, for example, when the chip socket contact 101 and the chip pin contact 102 are deviated from each other, in this case, the insertion may damage the first elastic arm 1011 of the chip socket contact 101 or cause an excessive local pressure at the insertion interface, and may cause the other first elastic arm 1011 and the chip pin contact 102 to be in non-contact to form a gap 105, or make a virtual contact, which may cause an excessive contact resistance between the chip pin contact 102 and the chip socket contact 101, and the temperature is increased during electrical signal transmission, and the chip socket contact is easily burnt. This problem also exists when the circular receptacle contact 103 and the circular pin contact 104 are mated.

The utility model provides a specific embodiment 1 of contact:

as shown in fig. 6 to 11, the contact 202 in the present embodiment is actually a sheet-type pin contact, and is inserted into a receptacle-type mating contact 600 in use. For convenience of description, the end of the contact 202 opposite to the mating contact 600 is defined as a front end in the present embodiment. The contact 202 includes a contact body 2021 and an elastic member 2025.

The structure of the contact body 2021 is as shown in fig. 8, the contact body 2021 includes a platform 2022, the platform 2022 is a U-shaped structure and includes a first side wall 20221 and a second side wall 20222 which are oppositely arranged, a first elastic arm 20241 and a second elastic arm 20242 are fixed at the front end of the platform 2022, the first elastic arm 20241 is connected with the first side wall 20221, the second elastic arm 20242 is connected with the second side wall 20222, and the first elastic arm 20241 and the second elastic arm 20242 are in conductive communication through the platform 2022 and can transmit the same signal. The first elastic arm 20241 and the second elastic arm 20242 are arranged opposite to each other and can swing relative to each other, and here, the first elastic arm 20241 and the second elastic arm 20242 are defined as swinging inwards when swinging towards each other and swinging outwards when swinging away from each other. In this embodiment, the contact 202 is formed by bending integrally.

As shown in fig. 8, the first elastic arm 20241 and the second elastic arm 20242 are both obliquely arranged, and the front ends of the first elastic arm 20241 and the second elastic arm 20242 are both bent toward each other to form a closed end section 2027 at the front ends of the first elastic arm 20241 and the second elastic arm 20242, and the two closed end sections 2027 are engaged to form a closed end at the front end of the contact body 2021.

Since the first elastic arm 20241 and the second elastic arm 20242 extend obliquely and the front ends are bent toward each other, a convex corner position is formed at the front ends of the first elastic arm 20241 and the second elastic arm 20242. As shown in fig. 8, a protrusion 2026 is fixed at the corner position, wherein there may be one or more protrusions 2026, and the shape thereof may be circular, rectangular, polygonal, or the like. The protrusion 2026 mainly serves to reinforce the corner positions of the first elastic arm 20241 and the second elastic arm 20242, because the corner positions of the first elastic arm 20241 and the second elastic arm 20242 are weakest, but the corner positions mainly contact the mating contact 600 in use, and the weak positions are reinforced and thickened to ensure that the corner positions are not easily worn through, and ensure the reliability of connection between the contact 202 and the mating contact 600.

In order to ensure that the contact 202 and the mating contact 600 can be smoothly inserted, the edge of the protrusion 2026 (especially, the edge of the front end) and the first elastic arm 20241 and the second elastic arm 20242 are transited by a fillet or a chamfer, so that the front end of the protrusion 2026 and the elastic arms (including the first elastic arm 20241 and the second elastic arm 20242) are transited smoothly, the fillet or the chamfer plays a role of guiding and guiding during the insertion, and the clamping arm 601 of the mating contact 600 is guided to smoothly enter the outer portions of the first elastic arm 20241 and the second elastic arm 20242. As can be seen from fig. 7 and 8, the front ends of the first elastic arm 20241 and the second elastic arm 20242 are both branched structures, and are more easily deformed after being stressed, so as to ensure that the contact 202 and the mating contact 600 are smoothly inserted.

The contact 202 further includes an elastic member 2025, the elastic member 2025 is located between the first elastic arm 20241 and the second elastic arm 20242, specifically, as shown in fig. 6 and 7, the elastic member 2025 here is a U-shaped elastic sheet, the U-shaped elastic member 2025 includes two sides 2028 and a connecting section 2029 connecting the two sides 2028, the connecting section 2029 is bent and can be elastically deformed, and the sides 2028 are respectively pressed and matched with the first elastic arm 20241 and the second elastic arm 20242, so as to be tightly supported between the two elastic arms. To mount the elastic element 2025, as shown in fig. 7, the end portions of the two side edges 2028 are provided with a slot 2030, the rear end of the platform 2022 is fixed with the mounting arms 2023, the two mounting arms 2023 are in one-to-one correspondence with the two side edges 2028, the slot 2030 is fittingly clamped on the mounting arms 2023, and the front end of the elastic element 2025 is limited by the closing-in section 2027 to prevent coming off. Of course, the two mounting arms 2023 may be combined into one at the time of actual manufacturing.

Therein, the mating contact 600 is actually a socket contact, comprising two oppositely arranged clamping arms 601. In use, as shown in fig. 9 and 10, the contact 202 and the mating contact 600 are inserted into each other, and the clip arm 601 drives the first elastic arm 20241 and the second elastic arm 20242 to swing and fit together by means of elastic tightening. When the contact 202 and the mating contact 600 are aligned, the first elastic arm 20241 and the second elastic arm 20242 swing by the same magnitude under positive pressure and the two sides 2028 of the elastic member 2025 are closed. As shown in fig. 11, when the contact 202 and the mating contact 600 are deviated from each other, one of the clip arms 601 first contacts the first elastic arm 20241, a positive pressure is applied to the first elastic arm 20241, the first elastic arm 20241 transmits the positive pressure to the elastic member 2025, and the elastic member 2025 transmits the pressure to the second elastic arm 20242, so that the first elastic arm 20241 and the second elastic arm 20242 can twist in the same direction, and the second elastic arm 20242 can contact the other clip arm 601 to conduct electricity.
