Examples

Referring to fig. 1 to 3, the present embodiment provides an electrical connector, which is suitable for an inner base 3 having a receiving groove 321. The electrical connector 1 includes an elastic coupling portion 13, and a first fixing portion 121 and a second fixing portion 122 disposed on two sides of the elastic coupling portion, and the second fixing portion 122 is upwardly provided with a contact portion 11. The contact portion 11 includes an extension portion 112 and a bending portion 113, an electrical contact region is formed between the extension portion 112 and the coupling portion 13, and the bending portion 113 is bent toward a lower portion of the electrical contact region and connected to the second fixing portion 122 through the extension portion 112. The free end of the bending segment 113 is bent toward the extending segment to form an arc-shaped protrusion 111, and the free end thereof is located in the receiving slot 321, and the arc-shaped protrusion 111 at least partially protrudes out of the receiving slot 321 to be electrically connected to the external contact 41.

In the electrical connector, an electrical contact region is formed between the extension section 112 of the contact portion 11 and the coupling portion 13, and the bending section 113 of the contact portion 11 is bent toward the lower side of the electrical contact region and disposed on the second fixing portion 122 through the extension section, so as to be bent inward to achieve quick and efficient electrical contact. Particularly, the arc-shaped protrusion 111 newly formed at the free end of the bending section 113 is bent relatively to the whole and elastically guided to the inner end side of the contact area, so as to form the arc-shaped protrusion with a free end in the contact direction, and after being contacted, the arc-shaped protrusion can be elastically jointed on the matched external contact element 41 in a self-adaptive manner, so that the operability of elastic contact is remarkably improved, the free end of the contact part 11 which is bent and guided inwards is more flexible, the elastic resilience is better, the contact mode of the contact is greatly improved, the problem of breakdown caused by frequent joint work of the contact part 11 is avoided, and the whole service life of the electric connector 1 is prolonged.

Specifically, the electric connector 1 is configured as a contact piece having at least a contact portion 11, a fixing portion 12, a coupling portion 13, and an extending portion 14. Here, the fixing portion 12 in the middle portion of the contact body is formed with a first fixing portion 121 and a second fixing portion 122. The coupling portion 13 is butted between the first fixing portion 121 and the second fixing portion 122, and the extending portion 14 extends along the first fixing portion 121 to one of the outer end portions, and the contact portion 11 extends in a direction suitable for the external contact 41 to contact and is located at the other of the outer end portions. The contact head 11 is bent and guided with spring force on the inner end of the contact piece, which forms an arc-shaped projection 111 in the contact direction, the arc-shaped projection 111 being a free end and being able to perform a spring force-locking engagement adaptively after being contacted. In the present embodiment, a plurality of fixing portions 12 for base holding, and extending portions 14 and contact portions 11 located on different outer end sides are configured at the intermediate portions and the outer end portions of the contact pieces thereof. In particular, the contact portion 11 is bent with respect to the whole and is elastically guided to the inner end side of the contact piece to form an arc-shaped protrusion 111 having a free end portion in the contact direction, so that it can be elastically engaged with the mating external contact member 41 adaptively after being contacted.

In one embodiment, the extending section 112 of the contact portion 11 is smoothly abutted on the upper side of the second fixing portion 122, and the arc-shaped protrusion 111 is disposed at the end of the bending section 113. Specifically, the extension section 112 smoothly extends upward from the outer edge of the second fixing portion 122 and is inclined inward to form a certain inclination angle, so as to enhance the resilience of the contact portion 11 at the outer end position.

The bending section 113 is U-shaped, and the arc protrusion 111 protrudes inward relative to the extending section 112 and bends outward and extends, and is freely spaced from the extending section 112. The arc-shaped protrusion 111 at the end of the bending section 113 is opposite to the extending section 112 at a distance, and the end of the arc-shaped protrusion 111 has a smaller distance from the extending section 112 after being bent back. Thus, the free end portion thereof is suspended at the distal end position, and a larger swing margin in the contact direction can be provided to the contact portion 11.

As shown in fig. 2 and 3, in one embodiment, the thickness of the electrical connector 1 is the same, and in particular, the functional components of the electrical connector 1 have the same thickness, but the widths in the front projection are different. The coupling portion 13 is configured as a U-shaped flexible portion 131 that is elastically deformable in the left-right direction, and both sides of the U-shape are connected to the first fixing portion 121 and the second fixing portion 122. The width of the middle of the two sides is smaller than the width of the top and the width of the root of the two sides when projected in the X-axis direction (in the forward projection direction of the electrical connector 1 shown in fig. 3). In the present embodiment, the two sides of the coupling portion 13 gradually increase in width from the middle to the bottom thereof when projected in the X-axis direction, so that a large rounded corner connection is formed where the two sides respectively meet the first fixing portion 121 and the second fixing portion 122. Thus, both ends of the U-shape extend horizontally and abut against the fixing portions 12, respectively. The U-shaped flexible portion 131 has an increased width at its end and its bottom, so that a large rounded corner connection with an R-angle is formed between the two sides and the respective fixing portions 12 and at the joint of the two sides. Furthermore, the R-angle connection increases the width of the U-shaped flexible portion 131 at the top and the root, and the width of the two sides is smaller, so as to ensure the connection strength and elastic deformation force of the entire flexible portion.

In particular, the U-shaped bent section 113 and the U-shaped flexible section 131 are arranged in a bent direction and in an orientation to the electrical connector substantially in agreement with each other, and are bent downward. And the height of the bending datum of the U-shaped bending section 113 is slightly greater than the bending datum height of the U-shaped flexible part 131, so as to define the contact position of the arc-shaped protrusion 111, which is convenient for the arc-shaped protrusion 111 to further implement abutting fit with the external contact element 41.

As shown in fig. 2 and 3, in an embodiment, the electrical connector 1 has the same thickness, a projection of the second fixing portion 122 in the X-axis direction is in a shape of a sheet, and the extension section 112 is formed by extending upward from a part of the second fixing portion 122 in the shape of a sheet. In particular, the electrical connector 1 has uniform thickness among the components, which facilitates mass production and maintains certain strength.

When the electrical connector 1 projects in the X-axis direction, the second fixing portion 122 is rectangular sheet-shaped, and the width of the extending section 112 is smaller than the length or width of the rectangular sheet-shaped. In particular, the second fixing portion 122 is recessed downward to form a connection lead angle with the extension section 112. This allows the longest moment arm to be obtained in a limited length of space, which is advantageous for increasing the elastic force of the contact portion 11.

As shown in fig. 2 and fig. 3, in an embodiment, the second fixing portion 122 is provided with a plurality of positioning convex hulls 1221, and the positioning convex hulls 1221 are distributed on front and rear sides of the second fixing portion 122. Further, the positioning convex hulls 1221 have four, two of the opposite corners are located at the front, and two of the opposite corners are arranged at the other side. Therefore, the second fixing portion 122 has a plurality of positioning convex hulls 1221 provided at the front and rear surfaces thereof in a staggered manner, and the positioning convex hulls 1221 of either end surface are provided diagonally to each other. Wherein each positioning projection is formed by punching and pressing the contact pieces integrally and cooperates with each other symmetrically to define the central assembling position of the whole electric connector 1. For the mounting fit between the second fixing portion 122 on the inner base 3 and the second mounting cavity 34, refer to the following description in the floating connector.

In this embodiment, the fixing portion 12 is provided with a plurality of positioning protrusions 1221, and the positioning protrusions 1221 are distributed on the left and right sides of the second fixing portion 122, so that when the electrical connector 1 is mounted on the inner base 3, the contact portion 11 is located at the central position in the receiving groove 321. In particular, the width of the receiving groove 321 is greater than the thickness of the contact part 11 to facilitate the arc-shaped protrusion 111 to elastically move between the receiving groove 321 and the engaging space.

Further, the outer periphery of the second fixing portion 122 is L-shaped and linear, and the inner periphery thereof is configured as a special-shaped protrusion structure for facilitating the fitting and fixing. The L-shaped linear outer peripheral edge facilitates smooth engagement with the extension portion 14 at the top and engagement with the coupling portion 13 at the side. And the edge part of the inner side periphery of the special-shaped protrusion structure is arranged in a relatively steep concave-convex manner, so that the rapid and efficient interference fit in the second mounting cavity 34 can be formed.

In one embodiment, the first fixing portion 121 extends outward to form an extending portion 14 for electrical connection, and a plug is disposed between the first fixing portion 121 and the extending portion 14. Thus, the first fixing portion 121 is configured as a plug for engaging and abutting to limit the position of the first fixing portion 121, and the plug is extended upward at the joint of the first fixing portion 121 and the extending portion 14. For the mounting fit between the first fixing portion 121 and the first mounting cavity 21 on the outer base 2, refer to the following description in the floating connector.

More specifically, as shown in fig. 1 and 2, the inclination angle of the extension section 112 is between 2 ° and 5 °, and the elastic force and the service life of the contact portion 11 thereof are optimized at an inclination angle of 3 °. The U-shaped bending segment 113 has a bending angle of 10 ° to 20 ° with respect to the extending segment 112, and the effect is particularly significant at a bending angle of 15 °. In addition, the protruding angle of the arc protrusion 111 is in a bending radian of 130 degrees to 150 degrees along the bending section 113, and the optimal return bending setting is achieved at a bending radian of 137 degrees.

In one embodiment, the electrical connector 1 is formed by stamping in one step and is made of a metal conductive material. It should be mentioned that, conventionally, the required shape is punched out first, then the bending is performed, and finally the electric connector finished product is formed after cutting, and the working procedures are various. After bending, the electrical connector can be unfolded to different degrees due to internal stress, so that the final shape of the electrical connector is different, and the quality of the electrical connector is affected finally. In the embodiment, the electric connector 1 is formed by stamping once, so that the shape consistency of the electric connector 1 is ensured, and the quality of the electric connector 1 is obviously improved.

Referring to fig. 4 to 7, the present embodiment further provides a floating connector including an outer housing 2, an inner housing 3, and an electrical connector passing through the outer housing 2 and the inner housing 3 and held by both. The inner base 3 is provided with a jogged part 31 for the external plug connector to be jogged and butted, the outer base 2 is loaded with the inner base 3 in a movable mode through a plurality of electric connectors, and the electric connectors are arranged regularly. The engaging portion 31 of the inner base 3 defines a receiving groove 321, the contact portion 11 is mounted in the receiving groove 321, the arc protrusion 111 is at least partially exposed out of the receiving groove 321, and the free end portion thereof is bent back and extends into the receiving groove 321 and is in a suspended state at an initial position.

The upper end of the extension section 112 is bent toward the bottom of the receiving groove 321 to form a bent section 113, an arc protrusion 111 for forming an electrical contact between the contact portion 11 and the external contact element 41 is disposed on the bent section 113, at least a portion of the arc protrusion 111 is located in the engaging space, and the free end of the arc protrusion is located in the receiving groove 321 after being bent toward the extension section 112. Therefore, the contact part 11 is provided with the elastic arm lengthened after the connection of the extension section 112 and the bending section 113, so that the elastic resetting force is improved, and the problems of jamming, collapse and the like of the electric connector 1 are greatly avoided.

In the above, the coupling portion 13 abutting between the two fixing portions 12 is elastically deformed to allow the two bases to move freely, so as to generate a floating displacement, thereby compensating the problem of alignment and plugging between the floating connector and the plug connector mated therewith. The accommodating groove 321 formed in the engaging portion 31 of the inner base 3 is used for installing and placing the contact portion 11, at least part of the arc protrusion 111 of the contact portion 11 is exposed outside the groove, the free end portion of the arc protrusion is suspended in the accommodating groove 321 in a manner of bending back and extending, reliability of a contact process is greatly improved, the suspended free end portion can provide a swing allowance for the contact portion 11 in a contact direction, and the contact manner is more flexible and reliable by matching with elastic recovery of the contact portion 11.

As shown in fig. 5 and 7, in one embodiment, the receiving groove 321 is regularly opened on the base portion 32 formed by the fitting portion 31 corresponding to the contact portion 11 of each electrical connector 1, and the receiving groove 321 is penetratingly provided at least above and outside the base portion 32. On one hand, the through accommodating groove 321 facilitates a one-time demolding mode of the base in the integral manufacturing process, and the manufacturing process is simplified. On the other hand, the receiving groove 321 penetrating upward allows the bending section 113 of the contact portion 11 to be more freely disposed in the groove without being constrained, and the height of the base portion 32 can be set lower than the bending reference height of the bending section 113, thereby greatly saving the manufacturing cost of the base. In addition, the receiving groove 321 penetrating to the outside can allow the arc-shaped protrusion 111 to be exposed, thereby performing an operation of abutting against the contact 41 outside the base portion 32.

More specifically, a clamping space for accommodating the plug connector is formed between the outer body 33 of the inner base 3 and the base 32 located in the middle, and the arc-shaped protrusion 111 is at least partially located in the clamping space for abutting fit with the external contact 41. In the present embodiment, the height of the bending segment 113 is shorter than the height of the base 32, and the arc-shaped protrusion 111 protrudes laterally to be exposed in the engaging space. In addition, base 32 is sunk in the inner base such that the height of base 32 is smaller than the height of outer body 33.

In addition, the outer edge of the outer body 33 is provided with notch structures at two ends in the length direction, and the whole outer body 33 enables the parts which are attached to the outer body 33 to be mutually replaced along the projection direction without any overlapping, so that the cost of the insulating rubber shell is reduced, and a quick production mode of one-time demoulding can be realized.

It should be noted that the bottom of the inner base 3 is configured with the second mounting cavity 34 communicating with the receiving groove 321, and the second fixing portion 122 can be embedded and clamped in the second mounting cavity 34, so that the extending section 112 and the groove wall of the receiving groove 321 are in clearance fit with each other. Specifically, the second fixing portion 122 and the second mounting cavity 34 are in interference fit with each other, and the second mounting cavity 34 is configured as a fitting groove facilitating the engagement and centering of the second fixing portion 122. The fitting of the second fixing portion 122 in the fitting groove in a centered manner is achieved by positioning bosses 1221 regularly provided on the front and rear surfaces of the second fixing portion 122.

Particularly, as shown in fig. 7, the second fixing portion 122 is provided with a clamping portion (not shown) for preventing the electrical connector 1 from being separated from the inner base, the clamping portion is disposed opposite to the extension section 112, and a side of the second fixing portion 122 close to the extension section 112 abuts against a wall of the second mounting cavity 34 through the clamping portion. In the direction from bottom to top, the gap between the extension section 112 and the groove wall of the receiving groove 321 is gradually increased, so that the bending section 113 with the arc-shaped protrusion 111 is obliquely arranged toward the inner end side of the electrical connector 1. In the above, the second fixing portion 122 abuts against the inner wall of the second mounting cavity 34, and the extending section 112 extends smoothly upward from the outer edge of the second fixing portion 122 and inclines inward to form a certain inclination angle, so that the extending section 112 has different gaps in the groove wall, and the closer to the bending reference height, the larger the gap between the contact portion 11 and the groove wall is, such a design manner can further enhance the elastic force of the contact portion 11 during the contact connection process. When the external contact member 41 abuts on the arc-shaped protrusion 111, the elastic force of the extension section 112 on the second fixing portion 122 swings, so that the contact stress is relieved. The self-elastic recovery of the arc-shaped protrusion 111 at the free end is not further implemented until the extension section 112 is completely attached to the groove wall, so as to achieve the purpose of multi-mode contact reset rebound.

In one embodiment, the bottom of the outer base 2 is configured with a first mounting cavity 21, the first fixing portion 121 is embedded and clamped in the first mounting cavity 21, and the first fixing portion 121 and the second fixing portion 122 are located at the same reference position. As is evident, the external base 2 and the internal base 3 are elastically assembled together by means of a plurality of electrical connectors 1, with the bottom of each base being substantially flush so as to be placed on an external circuit board, implementing an electrical connection of its extension 14 with the outside.

As shown in fig. 6 and 7, the second fixing portion 122 can be inserted into and engaged with the second mounting cavity 34, and the coupling portion 13 is disposed between the outer base 2 and the inner base 3 and relatively moved forward to be close to the first mounting cavity 21 of the outer base 2 so as to be away from the second mounting cavity 34. In this embodiment, the coupling portion 13 that has elastic deformation is specifically arranged to move forward between the outer base 2 and the inner base 3, so as to be away from the second mounting cavity 34, on one hand, the distance between the coupling portion 13 and the two bases is increased, the floating amount threshold is increased, and the heat dissipation configuration between the bases is facilitated, on the other hand, the second fixing portion 122 is fixedly embedded in the second mounting cavity 34, and the coupling portion 13 moves forward to be away from the second fixing portion 122 and the second mounting cavity 34, so that the stress applied to the electrical connector 1 is ensured to move forward to the coupling portion 13 with elastic force in the floating process, and the tensile strength and the compressive strength of the whole electrical connector can be obviously improved.

Wherein, the distance between one side of the U-shaped flexible portion 131 and the outer wall of the inner base 3 is larger than the distance between the other side of the U-shaped flexible portion and the inner wall of the outer base 2. Thus, the coupling portion 13 is formed into a U-shaped flexible portion 131 which is elastically deformable in the left-right direction, and has both sides at different intervals between the inner base 3 and the outer base 2, and has sides at a larger interval between the outer walls of the inner base 3 for the purpose of leading the stress away from the inner base 3.

With reference to fig. 8 to 10, the present embodiment further provides a plug connector, including: a plug-fit portion 4 and a contact 41. The mating portion 4 is for mating with the floating connector, and the contact element 41 is elastically abutted against the contact portion 11 after mating to form a contact connection. In this embodiment, the mating portion 4 of the plug connector and the mating portion 31 of the floating connector are mated with each other to form an electrical connection between the two connectors.

The contact 41 is an L-shaped plate, and has a short side exposed to the outer end side of the plug connector and a long side vertically arranged to the inner end side of the plug connector to press the contact portion 11 in a lateral direction. The contact 41 is formed by blanking and stamping, and the thickness of the short side is smaller than that of the long side. Thus, the shorter side of smaller length and smaller width facilitates direct integral soldering with an external ic, and the longer side of larger length and larger width is adapted to be in front face-to-face elastic abutting opposition with the arc-shaped projection 111 of the contact portion 11.
