Description

Technical Field

[0001] This utility model relates to the field of connector technology, specifically to a connector socket and battery holder connector. Background Technology

[0002] A battery socket connector is a connector used to connect the internal controller of an electronic product to the battery. It includes a connector socket and a connector plug. The connector plug is used to connect the battery, and the connector socket is used to connect the controller. The battery socket connector enables the battery to supply power to the controller. The reliability and stability of the connection between the connector socket and the connector plug are important factors for a stable and continuous power supply.

[0003] As market demand for high-performance, lightweight, and portable mobile devices increases, battery connectors, as a crucial component, are also trending towards miniaturization. However, due to space constraints, the existing method of relying on plastic protrusions on both sides for fastening is insufficient to ensure a tight fit between the connector socket and the connector plug, especially for detachable battery connectors, where frequent plugging and unplugging can easily lead to loosening of the interface. To address this issue, some products achieve a tight fit by creating an opening on the inner side of the plastic body of the connector socket and embedding a metal structural locking point at the opening to engage with the plastic locking point on the connector plug.

[0004] However, the above technical solutions have at least the following technical problems: 1. Metal structure locking points are prone to scratching plastic locking points, thus affecting the service life and mating stability of the connector; 2. Due to the small wall thickness, the opening part is at risk of breakage. Utility Model Content

[0005] This utility model provides a connector socket and battery holder connector, which solves the problems in the prior art where the mating of metal parts and plastic parts easily scratches the plastic locking points and the plastic body opening on the connector socket is easily broken. This improves the stability of the mating between the connector socket and the connector plug and extends the service life of the connector socket.

[0006] To solve the above-mentioned technical problems, the first aspect of this utility model provides a connector socket, including a socket plastic body, a insertion space on the socket plastic body, first limiting portions on both sides of the insertion space, and an installation groove on the socket plastic body near the first limiting portions; a metal spring sheet is installed in the installation groove, and when the first limiting portion is compressed, the pressure can be transmitted to the metal spring sheet through the thin wall between the installation groove and the first limiting portion, causing the metal spring sheet to undergo elastic deformation.

[0007] The connector socket provided in the above embodiment has a first limiting part that contacts the connector plug during use. This avoids scratching the plastic contacts on the connector plug due to direct contact between the metal spring and the plastic contacts, ensuring the stability of the connection between the connector socket and the connector plug and extending the connector's service life. The metal spring indirectly supports the first limiting part through the inside of the mounting groove, ensuring that the first limiting part and the plastic contacts on the connector plug are continuously in a tight fit, further guaranteeing the stability of the connection. At the same time, it avoids the risk of breakage caused by reducing the wall thickness of the connector socket's plastic body due to a single-sided opening.

[0008] As an improvement, the metal spring includes a fixing part, a positioning part disposed above the fixing part, and elastic arms. The fixing part extends through to the lower part of the socket's plastic body. The positioning parts are disposed on both sides of the elastic arms. The elastic arms abut against the inner wall of the mounting groove. A positioning groove is formed in the mounting groove, and the positioning part can be embedded in the positioning groove. Its function is to: provide support for the first limiting part by the elastic arms abutting against the inner wall of the mounting groove; stabilize the female seat by connecting to the fixing plate or circuit board by the fixing part; and facilitate the installation and positioning of the metal spring through the cooperation between the positioning part and the positioning groove.

[0009] As an improvement, a clearance groove is provided within the mounting groove, located on the side near the first limiting part. The elastic arm abuts against the side wall of the clearance groove, and an anti-retraction platform is provided at one end of the clearance groove, with the elastic arm abutting against the anti-retraction platform. Its function is to: accommodate the elastic arm through the clearance groove, reducing the volume of the mounting groove and ensuring the strength of the socket's plastic body; and limit the elastic arm through the anti-retraction platform, preventing the metal spring from loosening.

[0010] As an improvement, the fixing part is provided with outwardly protruding snap-fit ​​parts on both sides. Their function is to facilitate the installation and positioning of the fixing part, and to ensure the stability of the female seat installation.

[0011] As an improvement, the socket's plastic body is equipped with an automatic suction unit. Its function is to enable it to be adapted for automated assembly production.

[0012] The second aspect of this utility model provides a battery socket connector, including the connector socket described above, and also includes a connector plug. The connector plug includes a plug plastic body, and the outer contour of the plug plastic body is provided with a fourth limiting part that can be engaged with the first limiting part. After the first limiting part and the fourth limiting part are engaged, the movement of the plug plastic body along a first direction can be restricted.

[0013] The aforementioned battery holder connector completes the connection between the connector socket and the connector plug through the engagement of the first limiting part and the fourth limiting part. During the engagement process, all contact parts are made of plastic material, which can reduce scratches and extend the service life of the battery holder connector. After engagement, the metal spring can provide elastic support for the first limiting part, thereby ensuring the stability of the engagement between the connector socket and the connector plug.

[0014] As an improvement, the insertion space is provided with a second limiting part for restricting the movement of the plug plastic body along the second direction, and the outer contour of the plug plastic body is provided with a fifth limiting part that matches the second limiting part, wherein the second direction is perpendicular to the first direction. Its function is to enhance the stability of the connector plug installation by limiting the movement of the second and fifth limiting parts in the second direction.

[0015] As an improvement, the second limiting part is a groove provided on both sides of the insertion space, and the fifth limiting part is a protrusion provided on both sides of the plug plastic body that can be engaged with the second limiting part. Its function is to simplify the mating of the connector socket and connector plug while meeting the miniaturization requirements.

[0016] As an improvement, a third limiting part parallel to the second limiting part is provided within the insertion space, and a sixth limiting part matching the third limiting part is provided on the outer contour of the plug plastic body. A boss protruding into the insertion space is provided between the second limiting part and the third limiting part, and the first limiting part is located on the boss. A slot is provided on the plug plastic body at a position corresponding to the boss. Its function is to further enhance the stability of the mating between the connector socket and the connector plug.

[0017] As an improvement, a pull strap is installed on the plug's plastic body. The pull strap is made of flexible material and includes a connecting part and a lifting part. A pull strap mounting opening is provided on the plug's plastic body, the size of which matches the cross-sectional dimensions of the connecting part. The free end of the connecting part passes through the pull strap mounting opening and connects to the lifting part. Its function is to facilitate the removal of the connector plug, reduce space occupation, and allow the pull strap to conform to the surface of the plug's plastic body after installation, lowering the overall height of the battery holder connector and meeting the requirements for a thinner and lighter design.

[0018] In combination with the above technical solutions, compared with the prior art, the embodiments of this utility model have at least the following beneficial effects:

[0019] 1. This utility model embodiment provides elastic support for the first limiting part by installing a metal spring in the plastic body of the socket, thereby avoiding direct contact between the metal spring and the fourth limiting part during the fastening process. This solves the problem that the metal structure locking point is easy to scratch the plastic locking point, thus affecting the service life and mating stability of the connector.

Detailed Implementation

[0033] To illustrate the technical features, objectives, and effects of this utility model in detail, the following description, in conjunction with the accompanying drawings and embodiments, provides a further detailed explanation. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this utility model.

[0034] Please see the appendix Figure 1-5 The first aspect of this utility model provides a connector socket, including a socket plastic body 11, a insertion space 117 on the socket plastic body 11, first limiting portions 112 on both sides of the insertion space 117, and an installation groove 115 on the socket plastic body 11 near the first limiting portions 112; a metal spring 12 is installed in the installation groove 115, and when the first limiting portion 112 is squeezed, the pressure can be transmitted to the metal spring 12 through the thin wall between the installation groove 115 and the first limiting portion 112, causing the metal spring 12 to undergo elastic deformation.

[0035] In the above embodiment, the metal spring 12 is installed in the mounting groove 115. During use, the part that contacts the connector plug is the first limiting part 112, which avoids scratching the plastic contacts on the connector plug due to direct contact between the metal spring 12 and the plastic contacts, thus ensuring the stability of the mating between the connector socket and the connector plug and extending the connector's service life. The metal spring 12 indirectly provides support for the first limiting part 112 through the inside of the mounting groove 115, ensuring that the first limiting part 112 and the plastic contacts on the connector plug are continuously in a tight fit, further guaranteeing the stability of the connection. Since the mounting groove 115 is located inside the plastic body 11 of the socket, it also avoids the risk of breakage due to the small wall thickness of a single-sided opening, thereby extending the service life of the connector.

[0036] Based on the above embodiments, the metal spring 12 includes a fixing part 121, a positioning part 122 disposed above the fixing part 121, and an elastic arm 123. The fixing part 121 extends to the lower part of the socket plastic body 11. The positioning part 122 is disposed on both sides of the elastic arm 123. The elastic arm 123 abuts against the inner wall of the mounting groove 115. Positioning grooves 1151 are formed on both sides of the mounting groove 115, and the positioning part 122 can be embedded into the positioning grooves 1151. The fixing part 121 is used to connect the fixing plate or circuit board inside the electronic product, which can stabilize the connector socket. The elastic arm 123 abuts against the inner wall of the mounting groove 115 to provide elastic support for the first limiting part 112. The cooperation between the positioning part 122 and the positioning groove 1151 can facilitate the installation and positioning of the metal spring 12 and simplify the installation process.

[0037] Based on the above embodiments, a first limiting part 112 is provided in the mounting groove 115, and a clearance groove 1152 is located on the side close to the first limiting part 112. An elastic arm 123 abuts against the side wall of the clearance groove 1152, and an anti-reverse platform 1153 is provided at one end of the clearance groove 1152. The elastic arm 123 abuts against the anti-reverse platform 1153. The clearance groove 1152 is used to accommodate the elastic arm 123 without reducing the wall thickness of adjacent parts. This ensures the strength of the socket plastic body 11 while meeting the installation requirements of the elastic arm 123. For example, the first limiting part 112 can be configured such that its projection facing the clearance groove 1152 covers the width of the clearance groove 1152, avoiding the concentration of the squeezing force during fastening at the location of the clearance groove 1152, which could lead to the risk of breakage at that location. To facilitate the installation of the metal spring 12, the mounting groove 115 can be configured to penetrate the socket plastic body 11 in the first direction. The metal spring 12 is pushed into the mounting groove 115 from top to bottom to complete the installation. The anti-retraction platform 1153 is set at the top of the clearance groove, and the top of the elastic arm 123 abuts against the lower surface of the anti-retraction platform 1153, thereby limiting the elastic arm 123 and preventing the metal spring 12 from loosening.

[0038] Based on the above embodiments, the fixing part 121 has outwardly protruding snap-fit ​​parts 1211 on both sides. When connected with the fixing plate or circuit board inside the electronic product, the snap-fit ​​parts 1211 can be easily installed and limited, ensuring the stability of the connector socket installation.

[0039] Based on the above embodiments, the socket plastic body 11 is provided with an automatic suction part 116. Specifically, the automatic suction part 116 is a platform extending outward from the upper surface of the socket plastic body 11. The automatic suction part 116 provides space for automatic adsorption in automated production, thereby meeting the needs of automated assembly production.

[0040] Please see the appendix Figure 6-9The second aspect of this utility model provides a battery holder connector, including the connector socket 1 provided in the above embodiments, and also includes a connector plug 2. The connector plug 2 includes a plug plastic body 21. The outer contour of the plug plastic body 21 is provided with a fourth limiting part 212 that can be engaged with the first limiting part 112. After the first limiting part 112 and the fourth limiting part 212 are engaged, the movement of the plug plastic body 21 along the first direction can be restricted.

[0041] In the above embodiments, during the insertion of the connector socket 1 and the connector plug 2, the parts that contact the plug plastic body 21 and the socket plastic body 11 are the first limiting part 112 and the fourth limiting part 212. The metal spring 12 does not directly contact the fourth limiting part 212, which can avoid scratching the fourth limiting part 212 and ensure the stability of the connection between the connector plug 2 and the connector socket 1 and the service life of the connector. When fastened, the fourth limiting part 212 presses the first limiting part 112, causing the thin wall between the mounting groove 115 and the first limiting part 112 to deform, thereby transmitting pressure to the metal spring 12. The metal spring 12 undergoes elastic deformation to generate a reset elastic force, so that the first limiting part 112 can be reset in time after the fastening is completed, thereby restricting the fourth limiting part 212 from moving in the first direction. At the same time, the elastic support of the metal spring 12 can keep the first limiting part 112 in contact with the fourth limiting part 212, so that the connector plug 2 and the connector socket 1 are always in a tight fit, further ensuring the stability and reliability of the connection.

[0042] To further improve the stability of the engagement between the first limiting part 112 and the fourth limiting part 212, the first limiting part 112 can be configured as protrusions on both sides of the inner plastic body 11 of the socket, and the fourth limiting part 212 can be configured as protrusions on both sides of the plastic body 21 of the plug, wherein the engagement surface of the protrusions is curved. During the engagement process, the first limiting part 112 and the fourth limiting part 212 maintain line contact, which has better stability than point contact. The curved engagement surface makes the engagement and disengagement process smoother, reduces wear, and extends service life.

[0043] Based on the above embodiments, the insertion space 117 is provided with a second limiting part 111 for restricting the movement of the plug plastic body 21 along the second direction, and a fifth limiting part 211 matching the second limiting part 111 is provided on the outer contour of the plug plastic body 21. The second direction is perpendicular to the first direction. By limiting the second limiting part 111 and the fifth limiting part 211 in the second direction, the stability of the connector plug 2 installation can be enhanced.

[0044] Based on the above embodiments, the second limiting part 111 is a groove provided on both sides of the insertion space 117, and the fifth limiting part 211 is a protrusion provided on both sides of the outer contour of the plug plastic body 21 that can be inserted into the groove. This structure makes the mating of the connector plug 2 and the connector socket 1 simpler and more suitable for the needs of miniaturization.

[0045] Based on the above embodiments, a third limiting part 113 parallel to the second limiting part 111 is provided in the insertion space 117, and a sixth limiting part 213 matching the third limiting part 113 is provided on the outer contour of the plug plastic body 21. A boss 114 protruding into the insertion space 117 is provided between the second limiting part 111 and the third limiting part 113. The first limiting part 112 is located on the boss 114, and a slot 214 is provided on the plug plastic body 21 at a position corresponding to the boss 114. Through the cooperation between the second limiting part 111 and the fifth limiting part 211, and the third limiting part 113 and the sixth limiting part 213, the connector plug 2 is limited in the second direction, increasing the limiting surface of the connector plug 2 and making the insertion of the connector plug 2 more stable.

[0046] Based on the above embodiments, a pull strap 22 is installed on the plug plastic body 21 to facilitate the removal of the connector plug 2. The pull strap 22 is made of a flexible material, allowing it to flexibly change shape to adapt to the installation environment without occupying additional installation space. Specifically, the pull strap 22 includes a connecting part 221 and a lifting part 222. A pull strap mounting opening 215 is provided on the plug plastic body 21. The size of the pull strap mounting opening 215 matches the cross-sectional size of the connecting part 221. The free end of the connecting part 221 passes through the pull strap mounting opening 215 and connects to the lifting part 222. Obviously, to facilitate the installation of the pull strap 22 and make the connector plug 2 easier to remove, the size of the pull strap mounting opening 215 should be larger than the cross-sectional size of the connecting part 221. After installation, the connecting part 221 can slide within the pull strap mounting opening 215 along its installation direction, so that when the connector plug 2 is removed, the lifting part 222 can rotate to the middle position of the plug plastic body 21, making the removal process more stable. Of course, to reduce wear on the pull strap, the lifting part 222 can also be fixed to the middle of the plug plastic body 21. For example, in order to make the pull strap 22 fit against the surface of the plug plastic body 21 after installation, reduce the overall height of the connector, and meet the requirements of thinness and lightness, the pull strap 22 can be designed to be flat.

[0047] The present invention and its embodiments have been described in detail above. This description is not restrictive, and the accompanying drawings only show some embodiments of the present invention. The actual structure is not limited thereto. Those skilled in the art, inspired by this description, can make various modifications, improvements, and substitutions without departing from the concept of the present invention, and all of these should fall within the protection scope of the present invention.
