Description

Floating electrical connector

The present invention relates to a floating electrical connector, and more particularly to a floating electrical connector having an S-type resilient terminal structure.

In the prior art, the floating connector has a fixed outer casing fixed to the base plate, a movable outer casing provided with the abutting groove, and a contact member jointly held by the fixed outer casing and the movable outer casing, and the docking groove is for receiving the butt joint. Since the movable housing can freely move relative to the fixed housing by the elastic force of the contact member, the misalignment generated when mating with the mating connector is eliminated. When the mating connector is reliably mated, the outer casing is not damaged or the contact member is plastically deformed. However, most of the contacts of the conventional floating connector are U-shaped or L-shaped elastic terminals, and the U-shaped or L-shaped elastic terminals have poor stability when deformed, and the deformation and deformation recovery capabilities are also generally .

Therefore, it is desirable to design a new type of floating electrical connector to improve the above problems.

The main purpose of this creation is to provide a floating electrical connector with a terminal having better deformation and deformation recovery performance.

In order to achieve the above objectives, the author adopts the following technical solution: a floating type An electrical connector having a mating direction, the floating electrical connector includes an insulative housing and a conductive terminal; the insulative housing includes a fixed body having an internal space and a floating body located in an internal space of the fixed body, the floating body having parallel to the docking The conductive terminal includes a contact portion extending in the butting direction and fixed to the two sides of the mating groove of the floating body, a holding portion fixed to the fixed body, and an S-shaped flexible portion connecting the contact portion and the holding portion; The flexible portion includes a first elastic circular arc portion and a second elastic circular arc portion respectively connected to the contact portion and the holding portion, and a connecting portion connected to the first and second elastic circular arc portions; The projection portion of the second elastic circular arc portion on a plane perpendicular to the mating direction overlaps.

Compared with the prior art, the present invention has at least the following effects: the projection portions of the first and second elastic circular arc portions on a plane perpendicular to the mating direction overlap, which has a better effect on controlling the smoothness of the deformation, and the S-type terminal Structural deformation and deformation recovery performance are also preferred.

Figure 5 is a cross-sectional view of the floating electrical connector shown in the fourth figure taken along the IV-IV direction.

Referring to the first figure, the present invention discloses a floating electrical connector 100. The floating electrical connector 100 includes an insulative housing and a conductive terminal 3. The insulative housing includes a fixed body 1 and a floating body located in the fixed body 1. The body 2 and the conductive terminal 3 are jointly held by both the fixed body 1 and the floating body 2.

Referring to the second to fourth figures, the fixed body 1 and the floating body 2 of the insulating body extend in the longitudinal direction. The fixing body 1 includes two side walls 11 extending in the longitudinal direction and two end walls 12 connecting the two side walls 11. The two side walls 11 and the two end walls 12 are enclosed around the frame portion and penetrate the frame portion in the butting direction. Internal space 10. A first terminal channel 111 for receiving the conductive terminal 3 is disposed outside the two side walls 11 of the fixed body 1. The floating body 2 has a base portion 20 located above the frame portion of the fixed body 1 and a concave wall 21 protruding downward from the center of the base portion 20 and extending into the inner space 10. The inner wall surface of the concave wall 21 is formed parallel to the mating direction. Docking groove 210. The docking slot 210 is configured to receive the abutting portion of the mating connector when the floating electrical connector 100 is mated with the mating connector (not shown), and is longitudinally adjacent to the mating slot 210 of the floating body 2 The concave wall 21 in the direction is provided with a second terminal channel 211 for receiving the conductive terminal 3. A terminal movable space 13 is also formed between the side wall 11 of the fixed body 1 and the concave wall 21 of the floating body 2.

The conductive terminal 3 includes a contact portion 31 extending in the mating direction and fixed to the floating body 2 , a holding portion 32 fixed to the fixed body 1 , and an S-shaped flexible portion 33 connecting the contact portion 31 and the holding portion 32 . The contact portion 31 of the conductive terminal is held by the second terminal channel 211 on both sides of the mating groove 210 of the floating body 2 by barb interference, and the holding portion 32 is also held by the barb interference on the outer side of the two side walls 11 of the fixed body 1 The terminal channel 111 and the holding portion 32 extend outwardly to form the fixing body 1 Soldering to a soldering portion 34 of a circuit board (not shown).

As can be seen from the fifth figure, the flexible portion 33 is located in the terminal movable space 13 and includes a first elastic arc portion 331 and a second elastic arc portion 332 respectively connected to the contact portion 31 and the holding portion 32. And a connecting portion 333 connected to the first and second elastic arc portions. The first elastic arc portion 331 and the second elastic arc portion 332 are spaced apart from the concave wall 21 of the floating body 2 and the side wall 11 of the fixed body 1 respectively, so that the flexible portion 33 can be in the terminal movable space 13 There is a certain amount of displacement space. In the butting direction, the end of the first elastic circular arc portion 331 is farther from the base portion 20 of the floating body 2 than the end of the concave wall 21 of the floating body 2. At the same time, the floating body 2 is openly formed at the outer side of the corresponding first elastic arc portion 331 to reduce the use of the side wall of the floating body on the outer side, thereby reducing the overall height of the floating electrical connector 100.

One ends of the first elastic arc portion 331 and the second elastic arc portion 332 are respectively tangent to the contact portion 31 and the holding portion 32, and the other ends of the first elastic circular arc portion 331 and the second elastic circular arc portion 332 are respectively The connecting portion 333 is tangent, and the sum of the diameters of the first elastic arc portion 331 and the second elastic arc portion 332 is larger than the distance between the contact portion 31 and the retaining portion 32, that is, the first elastic arc portion 331 and the second elastic circle. The projection portion of the arc portion 332 on the plane perpendicular to the mating direction overlaps such that the connecting portion 333 of the S-shaped flexible portion 33 forms an angle with the mating direction, so that the flexible portion 13 is "introverted" when deformed. The advantage of the deformation is that it only occurs within a small range of the terminal active space 13 of the insulative housing.

The floating electrical connector 100 is further provided with a metal fixing member 4 that is fastened to the two end walls 12 of the fixed body 1. The metal fixing member 4 includes a main body portion 41, and a fastening portion 42 that is bent and extended from both ends of the main body portion 41 and is fastened to the end wall 12 of the fixing body 1 and the main body The substrate fixing portion 43 is bent and extended at both ends of the portion 41. The fastening portion 42 of the metal fixing member 4 is fixedly mounted in the fastening groove 14 of the two end walls 12 of the fixing body 1.

An improvement of the present invention over the prior art is that the projection portions of the first elastic arc portion 331 and the second elastic arc portion 332 on a plane perpendicular to the mating direction overlap such that the connection portion of the S-shaped flexible portion 33 The negative angle between the 333 and the mating direction has a better effect on controlling the smoothness of the deformation, and the S-type terminal structure also performs better when subjected to deformation and deformation recovery.
