Description

Technical Field

[0001] This utility model relates to the field of signal connection technology, and in particular to a board-to-board connector female socket. Background Technology

[0002] In electronic products, electrical connectors are typically used to enable quick connection and disconnection between different devices. Existing connector female bodies are usually injection molded. During manufacturing or repeated use, due to the elongated shape of the female body, shrinkage and expansion can easily occur. Solving this shrinkage issue usually involves adding structural elements, such as increasing the aperture of the electrical contact pieces. However, increasing the aperture of the electrical contact pieces can lead to unstable contact positions or slight misalignment with the insertion direction. In such cases, the electrical contact pieces are prone to damage or excessive wear during use. Therefore, effectively balancing the shrinkage issue during the molding of the female body with maintaining the consistency of the electrical contact pieces with the insertion direction becomes a problem that needs to be solved. Utility Model Content

When the first conductive body is fixed to the female socket body, the fixing part abuts against the wall of the fixing hole. After the mounting plate is sleeved on the connecting part, it is fixed in the mounting cavity. The mounting plate causes one end of the clamping part to abut against the tail end of the fixing hole. The contact gap on the clamping part is on the same straight line as the limiting hole.

[0005] In one specific embodiment, the fixing part includes upper and lower fixing plates and side plates respectively connected to the same side of the upper fixing plate and the lower fixing plate. An opening is provided on the opposite side of the side plate. The clamping part includes an upper clamping arm, a lower clamping arm, and a clamping groove located between the upper clamping arm and the lower clamping arm. Each clamping arm has a contact piece at its end. One end of the upper clamping arm is connected to the upper fixing plate, and the other end is connected to the contact piece. One end of the lower fixing plate is connected to the lower clamping arm, and the other end is connected to another contact piece. One end of the lower fixing plate is connected to the connecting part. The contact gap is located between the two contact pieces and communicates with the clamping groove.

[0006] In one specific embodiment, a curved portion is provided between the connecting portion and the upper fixing plate, the curved portion making the connecting portion and the contact gap on the same straight line.

[0007] In one specific embodiment, the contact piece is arc-shaped, and the contact gap formed between the two contact pieces is larger on the outside and smaller on the inside.

[0008] In one specific embodiment, the two contact pieces are respectively provided with contact areas, the two contact areas are parallel to each other, and the two contact areas are not perpendicular to the direction of insertion in the length direction.

[0009] In one specific embodiment, the contact piece is wider than the upper clamping arm.

[0010] In one specific embodiment, the side plate is further provided with a protrusion on the side near the connecting part.

[0011] In one specific embodiment, the connector female socket further includes a second conductor mounted on the female socket body. The second conductor has a conductive part and a second welding part connected to the conductive part. The female socket body has a second mounting hole and a clearance hole communicating vertically with the second mounting hole. The width of the second mounting hole is greater than that of the clearance hole. The clearance hole and the second mounting hole communicate with a through groove on the female socket body. The bottom sides of the through groove are provided with clamping grooves for fixing the conductive part. During installation, the second conductor is located in the through groove.

[0012] In one specific embodiment, a stop block is provided at the end of the clamping groove.

[0013] In one specific embodiment, the female body further includes an insertion part and a limiting part, wherein the insertion part has a cross-sectional area smaller than the limiting part in the vertical direction of insertion, and the limiting part is provided with an anti-shrinkage groove.

[0014] In one specific embodiment, the upper and lower fixing plates, the upper and lower clamping arms, and the connecting part are not on the same plane.

[0015] In one specific embodiment, the upper and lower fixing plates are not less than twice the width of the clamping arm in both the length and width directions.

[0016] In one specific embodiment, the upper and lower fixing plates are arranged in parallel, and each fixing plate contacts the wall of the fixing hole when it is engaged with the square fixing hole.

[0017] This utility model discloses a board-to-board connector female base, comprising a female base body and a first conductive body disposed on the female base body. The female base also includes a mounting plate for fixing the first conductive body to the female base body. The female base body has a mounting cavity with a first mounting hole penetrating the female base body. The first conductive body includes a fixing part and a clamping part disposed at one end of the fixing part, and the other end is connected to a first welding part through a connecting part. The first mounting hole includes a fixing hole and a limiting hole that is in the same direction as the fixing hole and has a smaller diameter than the fixing hole. When the first conductive body is fixed to the female base body, the fixing part abuts against the wall of the fixing hole. After the mounting plate is sleeved on the connecting part, it is fixed in the mounting cavity. The mounting plate causes one end of the clamping part to abut against the tail end of the fixing hole, and the contact gap on the clamping part is on the same straight line as the limiting hole. Because the larger diameter fixing hole on the female body mates with the fixing part, and the contact gap on the clamping part mates with the larger diameter limiting hole, which is located in the middle of the limiting hole, after mating with the male body, the contact probe on the male body and the two contact pieces of the clamping part can function in the same way, and the contact pieces have a large variable space, avoiding easy damage or excessive wear during use when misalignment occurs. At the same time, the larger fixing hole can also effectively avoid the shrinkage phenomenon that is prone to occur during the molding process of the female body. Attached Figure Description

[0032] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0033] like Figure 1-6 As shown, this utility model provides an embodiment of a board-to-board connector female socket.

[0034] The board-to-board connector female includes a female body 1, a first conductor 3 disposed on the female body 1, and a mounting plate 2 for fixing the first conductor 3 to the female body 1. The female body 1 has a mounting cavity 11, and the mounting cavity 11 has a first mounting hole 12 penetrating the female body 1. The first conductor 3 includes a fixing part 30 and a clamping part 31 disposed at one end of the fixing part 30, and the other end is connected to a first welding part 32 through a connecting part 33. The first mounting hole 12 includes a fixing hole 121 and a limiting hole 122 that is in the same direction as the fixing hole 121 and has a smaller diameter than the fixing hole. When the first conductor 3 is fixed to the female body 1, the fixing part 30 abuts against the wall of the fixing hole 121. The mounting plate 2 is sleeved on the connecting part 33 and fixed in the mounting cavity 11. The mounting plate 2 causes one end of the clamping part 31 to abut against the tail end of the fixing hole 121. The contact gap on the clamping part 31 is on the same straight line as the limiting hole 122.

[0035] Specifically, the female base body 1 is provided with two sets of first mounting holes 12, each set of first mounting holes 12 including multiple first mounting holes 12. The number of first conductive bodies 3 corresponds to the number of first mounting holes 12. In this embodiment, the first mounting holes 12 are square, that is, the cross-section of the limiting hole 122 and the fixing hole 121 along the vertical direction of insertion is a square structure. The first conductive bodies 3 are integrally formed using copper or steel conductive materials. The mounting plate 2 is provided with holes corresponding to the number of first mounting holes 12. These holes match the first welding part 32 and the connecting part 33, that is, the first welding part 32 and the connecting part 33 can pass through these holes. The mounting plate 2 is provided with a buckle 22 on its side. When the mounting plate 2 is engaged with the mounting cavity 11, the buckle 22 engages with the upper groove 111 on the side wall of the mounting cavity 11, so that the mounting plate 2 is fixed on the female base body 1.

[0036] The fixing part 30 includes two fixing plates 300 and two side plates 303 connected to the same side of the two fixing plates 300 respectively. An opening 301 is provided on the opposite side of the side plate 303. The clamping part 31 includes two clamping arms 311 and a clamping groove 313 located between the upper clamping arms 311. Each clamping arm 311 has a contact piece 312 at its end. One end of the clamping arm 311 is connected to the fixing plate 300, and the other end is connected to the contact piece 312. That is, one end of the upper fixing plate is connected to the upper clamping arm, and the other end of the upper fixing plate is connected to the other end of the contact piece. One end of the lower fixing plate is connected to the lower clamping arm, and the other end of the lower clamping arm is connected to another contact piece. A contact gap 314 is formed between the upper and lower clamping arms 312, and the contact gap 314 communicates with the clamping groove 313.

[0037] To ensure that the fixing part 30 can form a good fixation with the square fixing hole 121, and to ensure that the contact gap 314 and the clamping groove 313 on the first conductor 3 are on the same straight line as the insertion direction, the upper and lower fixing plates 30 are arranged in parallel. The fixing plates 30 are not less than twice the width of the clamping arm in both the length and width directions. This ensures that each fixing plate 30 contacts the wall of the fixing hole to form a large contact surface when mating with the square fixing hole 121, and also ensures consistency with the direction of the fixing hole 121. The opening 301 ensures that the fixing part 30 has a certain amount of deformable space when it is interference-fitted with the fixing hole 121.

[0038] In one specific embodiment, the contact piece 312 is arc-shaped, and the contact gap 314 formed between the two contact pieces 312 has an open structure, i.e., larger on the outside and smaller on the inside, facilitating insertion. The contact piece 312 can be designed to be wider than the clamping arm 311 as needed, increasing the contact area during conduction and improving the stability of the electrical connection. Each of the two contact pieces 312 has a contact area 315, which are parallel to each other. The two contact areas are not perpendicular to the insertion direction in the length direction, i.e., the angle α formed by the contact area and the insertion direction is not 90 degrees. This ensures a smaller insertion contact surface during insertion of the conductive piece onto the male socket, reducing insertion resistance and making insertion easier. In the above embodiment, the upper and lower fixing plates, the upper and lower clamping arms, and the connecting part 33 are not common surfaces.

[0039] In one specific embodiment, a bent portion 330 is provided between the connecting portion 33 and the upper fixing plate 30. The bent portion 330 ensures that the connecting portion 33 is on the same straight line as the contact gap 314 when it is fixed by the mounting plate 2, thereby reducing deformation during the insertion process.

[0040] As needed, the side plate 303 is also provided with a protrusion 302 near the connecting part 33. The protrusion 302 can make the first conductor 3 abut against the tail of the fixing hole 121 when the mounting plate 2 is installed, so as to avoid it from becoming loose, and at the same time avoid the influence of the bending part 330 on fixing the first conductor 3.

[0041] Because the larger diameter fixing hole on the female body mates with the fixing part, and the contact gap on the clamping part mates with the larger diameter limiting hole, which is located in the middle of the limiting hole, after mating with the male body, the contact probe on the male body and the two contact pieces of the clamping part can function in the same way, and the contact pieces have a large variable space, avoiding easy damage or excessive wear during use when misalignment occurs. At the same time, the larger fixing hole can also effectively avoid the shrinkage phenomenon that is prone to occur during the molding process of the female body.

[0042] In one specific embodiment, the connector female socket further includes a second conductor 4 mounted on the female socket body 1. The second conductor 4 has a conductive part 40 and a second welding part 41 connected to the conductive part 40. The female socket body 1 has a second mounting hole 131 and a clearance hole 132 communicating vertically with the second mounting hole 131. The width of the second mounting hole 131 is larger than that of the clearance hole 132. The clearance hole 132 and the second mounting hole 131 communicate with a through groove 14 on the female socket body 1. The bottom sides of the through groove 14 have fixing grooves 141 for fixing the conductive part 40. When fixed, the second conductor 4 is partially located in the through groove 14. A stop block (not shown in the figure) is provided at the end of the through groove 14. The stop block partially or completely blocks the end of the conductive part 40, reducing the occurrence of the conductive part 40 lifting during use.

[0043] As needed, the female body 1 also includes an insertion part 15 and a limiting part 13. The insertion part 15 has a cross-sectional area smaller than the limiting part 13 in the vertical direction of insertion. The limiting part 13 is provided with an anti-shrinkage groove 10.

[0044] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
