Description

Technical Field

[0001] This utility model relates to the field of connector technology, and in particular to an electrical connector. Background Technology

[0002] Electrical connectors, as key components for achieving electrical connections, are widely used in the transmission of signals and power between various devices. Electrical connectors typically consist of male and female terminals, which are mated together to achieve an electrical connection.

[0003] There is an electrical connector used in products such as fascia guns and massagers. One of the male and female terminals is installed on the massage head, and the other of the male and female terminals is installed on the handle. When the handle is connected to the massage head, the male and female terminals are connected to achieve electrical connection, which facilitates the adaptation of the handle to different types of massage heads.

[0004] However, because such products vibrate at high frequencies during operation, the male and female terminals of the electrical connector can easily become loose. Utility Model Content

[0005] The main purpose of this utility model is to provide an electrical connector that allows for a tight fit between the male and female ends and prevents loosening.

[0006] To achieve the above objectives, the electrical connector proposed in this utility model includes:

[0007] The male end includes the first housing;

[0008] The female end includes a second housing; and

[0009] A first electrical connection assembly includes a spring and a cylindrical conductor, wherein one of the spring and the cylindrical conductor is disposed inside the first housing and the other is disposed inside the second housing;

[0010] The first housing is inserted into the second housing, so that the spring contact abuts against the cylindrical conductor to achieve electrical connection, and the spring contact generates an elastic force applied to the cylindrical conductor radially.

[0011] In one embodiment, the spring includes a support section, an elastic section, and a scratch-resistant section. One end of the elastic section is bent and connected to the support section, and the other end of the elastic section extends obliquely toward the cylindrical conductor. One end of the scratch-resistant section is bent and connected to the end of the elastic section near the cylindrical conductor, and the other end of the scratch-resistant section extends obliquely toward the support section. The bent connection between the elastic section and the scratch-resistant section is used to abut against the cylindrical conductor.

[0012] In one embodiment, the spring abuts against the inner wall of the cylindrical conductor, and two springs are provided and arranged opposite to each other; and / or,

[0013] The end of the support segment connected to the elastic segment is bent away from the cylindrical conductor.

[0014] In one embodiment, the first housing is provided with a first mounting groove, and the support section is at least partially inserted into the first mounting groove; or,

[0015] The second housing is provided with a second mounting groove, and the support section is at least partially inserted into the second mounting groove.

[0016] In one embodiment, the electrical connector further includes a second electrical connection assembly, which includes a center pin and a pin seat. The pin seat has a socket corresponding to the center pin. One of the center pin and the pin seat is located inside the first housing, and the other is located inside the second housing.

[0017] The first housing is inserted into the second housing, so that the center pin is inserted into the socket to achieve electrical connection.

[0018] In one embodiment, the central pin passes through the interior of the first housing and is coaxially arranged with the first housing; the cylindrical conductor is spaced out and sleeved around the outside of the central pin and is coaxially arranged with the central pin; and / or,

[0019] The needle holder has a notch at one end near the central needle. There are at least two notches that are spaced apart circumferentially along the needle holder, and each notch extends axially along the needle holder.

[0020] In one embodiment, the male end further includes a first circuit board, which is fixed inside the first housing, and the central pin and the cylindrical conductor are electrically connected to the first circuit board, respectively; and / or,

[0021] The female end also includes a second circuit board, which is fixed inside the second housing. The pin seat and the spring are electrically connected to the second circuit board.

[0022] In one embodiment, the electrical connector further includes a locking structure disposed between the first housing and the second housing for preventing the first housing from separating from the second housing along its own axial direction.

[0023] In one embodiment, the locking structure includes an undercut groove and a locking protrusion. The undercut groove is disposed on the outer wall of the first housing, and the locking protrusion is disposed on the inner wall of the second housing. The undercut groove includes a communicating guide groove and a locking groove. The guide groove extends obliquely from one end of the first housing near the second housing to the other end. The locking groove extends circumferentially along the first housing. The locking protrusion enters the locking groove through the guide groove to prevent the first housing from separating from the second housing along its own axial direction.

[0024] In one embodiment, the locking structure further includes an elastic ring. The outer wall of the first housing is provided with a limiting protrusion. The elastic ring is sleeved on the outside of the first housing and is located on the side of the limiting protrusion facing the second housing. The locking protrusion enters the locking groove, so that the second housing and the limiting protrusion squeeze and deform the elastic ring, so that the elastic ring generates an elastic force along its own axis.

[0025] The electrical connector in this utility model includes a male end, a female end, and a first electrical connection assembly. The first electrical connection assembly has a spring and a cylindrical conductor, one of which is disposed in the first housing of the male end and the other is disposed in the second housing of the female end. When the first housing of the male end is inserted into the second housing of the female end, the spring and the cylindrical conductor abut against each other to achieve electrical connection, thereby realizing the electrical connection between the male end and the female end. When the spring contacts are sleeved with the cylindrical conductor, the spring contacts undergo elastic deformation, generating elastic force. This elastic force is applied radially to the cylindrical conductor. On one hand, this makes the contact between the spring contacts and the cylindrical conductor more compact in the radial direction, improving the stability of the electrical connection between the male and female terminals. This allows the connector to effectively resist separation caused by external forces or vibrations, thus improving the reliability of the connector. On the other hand, it increases the radial normal pressure between the spring contacts and the cylindrical conductor, which in turn increases the static friction between them. This makes it less likely for the spring contacts and the cylindrical conductor to slide relative to each other in the axial direction, which in turn makes it less likely for the first and second housings to slide relative to each other in the axial direction. This allows the male and female terminals to effectively resist separation caused by external forces or vibrations. Furthermore, even if there is slight radial relative movement between the male and female terminals, the spring contacts have a certain radial displacement compensation capability, preventing separation between the spring contacts and the cylindrical conductor and improving the reliability of the electrical connection between the male and female terminals.

[0043] This utility model proposes an electrical connector.

[0044] Please see Figure 1 , Figure 2 and Figure 4 , Figure 1 This is a cross-sectional view of an embodiment of the electrical connector provided by this utility model. Figure 2 This is a schematic diagram of the structure of the male terminal of the electrical connector provided by this utility model. Figure 4 This is a schematic diagram of the female end of the electrical connector provided by this utility model.

[0045] In one embodiment of this utility model, the electrical connector includes:

[0046] Male end 100 includes a first housing 110;

[0047] The female end 200 includes a second housing 210; and

[0048] The first electrical connection assembly 300 includes a spring 310 and a cylindrical conductor 320, one of which is located inside the first housing 110 and the other is located inside the second housing 210.

[0049] The first housing 110 is inserted into the second housing 210, so that the spring piece 310 abuts against the cylindrical conductor 320 to achieve electrical connection, and the spring piece 310 generates an elastic force that is applied to the cylindrical conductor 320 radially.

[0050] The electrical connector in this utility model includes a male end 100, a female end 200, and a first electrical connection assembly 300. The first electrical connection assembly 300 has a spring piece 310 and a cylindrical conductor 320, one of which is disposed in the first housing 110 of the male end 100, and the other is disposed in the second housing 210 of the female end 200. When the first housing 110 of the male end 100 is inserted into the second housing 210 of the female end 200, the spring piece 310 abuts against the cylindrical conductor 320 to achieve electrical connection, thereby realizing the electrical connection between the male end 100 and the female end 200. When the spring contact 310 is sleeved with the cylindrical conductor 320, the spring contact 310 undergoes elastic deformation, generating elastic force. This elastic force is applied radially to the cylindrical conductor 320. On one hand, this makes the contact spring 310 and the cylindrical conductor 320 more tightly contacted in the radial direction, improving the stability of the electrical connection between the male terminal 100 and the female terminal 200. This allows the electrical connector to effectively resist separation caused by external forces or vibrations, thus improving the reliability of the electrical connector. On the other hand, it increases the radial normal force between the spring contact 310 and the cylindrical conductor 320, which in turn increases the strength of the contact spring 310 and the cylindrical conductor 320. The static friction between the cylindrical conductors 320 makes it difficult for the spring piece 310 and the cylindrical conductor 320 to slide relative to each other along the axial direction. This also makes it difficult for the first housing 110 and the second housing 210 to slide relative to each other along the axial direction, thus enabling the male end 100 and the female end 200 to effectively resist separation caused by external forces or vibrations. Furthermore, even if the male end 100 and the female end 200 experience slight radial relative movement, the spring piece 310 has a certain radial displacement compensation capability, preventing the spring piece 310 and the cylindrical conductor 320 from separating and improving the reliability of the electrical connection between the male end 100 and the female end 200.

[0051] In one embodiment, the spring 310 includes a support section 311, an elastic section 312, and a scratch-resistant section 313. One end of the elastic section 312 is bent and connected to the support section 311, and the other end of the elastic section 312 extends obliquely toward the cylindrical conductor 320. One end of the scratch-resistant section 313 is bent and connected to the end of the elastic section 312 near the cylindrical conductor 320, and the other end of the scratch-resistant section 313 extends obliquely toward the support section 311. The bent connection between the elastic section 312 and the scratch-resistant section 313 is used to abut against the cylindrical conductor 320.

[0052] Reference Figure 5 In this embodiment of the invention, the spring piece 310 includes a support section 311, an elastic section 312, and a scratch-resistant section 313. The support section 311, elastic section 312, and scratch-resistant section 313 are integrally formed by a bending process, reducing the manufacturing difficulty of the spring piece 310 and thus lowering manufacturing costs. The support section 311 provides fixation and support. The elastic section 312 is bent and connected to the support section 311, forming a V-shaped structure that improves the elastic performance of the elastic section 312. This structure is simple and easy to process. The end of the elastic section 312 near the cylindrical conductor 320 is bent towards the support section 311 to form the scratch-resistant section 313. The bend where the scratch-resistant section 313 connects to the elastic section 312 abuts against the cylindrical conductor 320, rather than the end of the spring piece 310 abutting against the cylindrical conductor 320. This prevents the spring piece 310 from scratching the cylindrical conductor 320 and extends the service life of both the spring piece 310 and the cylindrical conductor 320.

[0053] In one embodiment, the spring piece 310 abuts against the inner wall of the cylindrical conductor 320, and two spring pieces 310 are provided and arranged opposite to each other; and / or,

[0054] The end of the support section 311 connected to the elastic section 312 is bent away from the cylindrical conductor 320.

[0055] Combination Figure 1 , Figure 2 and Figure 4 In this embodiment of the invention, the spring piece 310 abuts against the inner wall of the cylindrical conductor 320, causing the spring piece 310 to deform inward. Compared to the embodiment where the spring piece 310 abuts against the outer wall of the cylindrical conductor 320, causing the spring piece 310 to deform outward, this embodiment causes less damage to the deformed part of the spring piece 310, which helps to extend the service life of the spring piece 310. In addition, there are two spring pieces 310, which are arranged back to back. By increasing the number of spring pieces 310, the number of contact points between the male end 100 and the female end 200 is increased. Even if one contact point has a problem, the other contact point can still maintain electrical connection, improving the reliability of the connection. Furthermore, the two back-to-back spring pieces 310 can generate more uniform radial pressure on the inner wall of the cylindrical conductor 320, which helps to maintain stable contact between the spring piece 310 and the inner wall of the cylindrical conductor, reducing poor contact or wear caused by uneven pressure.

[0056] Combination Figure 1 and Figure 5In an embodiment of this utility model, the end of the support segment 311 connected to the elastic segment 312 is bent away from the cylindrical conductor 320. This facilitates the bending operation of the elastic segment 312 and the anti-scratch segment 313, and slightly increases the distance between the elastic segment 312 and the support segment 311, which helps to improve the elasticity of the elastic segment 312.

[0057] In one embodiment, the first housing 110 is provided with a first mounting groove, and the support section 311 is at least partially inserted into the first mounting groove; or,

[0058] The second housing 210 is provided with a second mounting groove, and the support section 311 is at least partially inserted into the second mounting groove.

[0059] In the embodiments of this utility model, when the spring piece 310 is installed on the male end 100, that is, when the spring piece 310 is set in the first housing 110, the first housing 110 is provided with a first mounting groove, and the support section 311 is inserted into the first mounting groove, which improves the convenience of assembling the spring piece 310 with the first housing 110, improves the reliability of the spring piece 310 installation, and reduces the possibility of the spring piece 310 loosening or falling off during deformation.

[0060] In the embodiments of this utility model, when the spring piece 310 is installed on the female end 200, that is, when the spring piece 310 is set in the second housing 210, the second housing 210 is provided with a second mounting groove, and the support section 311 is inserted into the second mounting groove, which improves the convenience of assembling the spring piece 310 with the second housing 210, improves the reliability of the spring piece 310 installation, and reduces the possibility of the spring piece 310 loosening or falling off during deformation.

[0061] In one embodiment, the electrical connector further includes a second electrical connection assembly 400, which includes a center pin 410 and a pin seat 420. The pin seat 420 is provided with a socket 421 corresponding to the center pin 410. One of the center pin 410 and the pin seat 420 is located inside the first housing 110, and the other is located inside the second housing 210.

[0062] The first housing 110 is inserted into the second housing 210, so that the center pin 410 is inserted into the socket 421 to achieve electrical connection.

[0063] Reference Figure 1 , Figure 2 and Figure 4In an embodiment of this utility model, the electrical connector further includes a second electrical connection assembly 400. The second electrical connection assembly 400 includes a center pin 410 and a pin seat 420. One of the center pin 410 and the pin seat 420 is disposed in the first housing 110 of the male end 100, and the other is disposed in the second housing 210 of the female end 200. When the first housing 110 of the male end 100 is inserted into the second housing 210 of the female end 200, the center pin 410 is inserted into the socket 421 of the pin seat 420 to achieve electrical connection, thereby realizing the electrical connection between the male end 100 and the female end 200. The provision of two sets of electrical connection structures, the first electrical connection assembly 300 and the second electrical connection assembly 400, can be used to meet the transmission requirements of different electrical signals and can also be used to distribute current loads.

[0064] In one embodiment, the center pin 410 passes through the interior of the first housing 110 and is coaxially arranged with the first housing 110, while the cylindrical conductor 320 is spaced around the outside of the center pin 410 and is coaxially arranged with the center pin 410; and / or,

[0065] The needle holder 420 has a notch 422 at one end near the center needle 410. There are at least two notches 422 and they are distributed at intervals along the circumference of the needle holder 420. Each notch 422 extends along the axial direction of the needle holder 420.

[0066] Reference Figure 1 , Figure 2 and Figure 4 In this embodiment of the invention, the needle holder 420 and the spring piece 310 are disposed inside the first housing 110, i.e., both the needle holder 420 and the spring piece 310 are located at the male end 100. The center needle 410 and the cylindrical conductor 320 are disposed inside the second housing 210, i.e., both the center needle 410 and the cylindrical conductor 320 are located at the female end 200. The needle holder 420 and the first housing 110 are coaxially arranged, the spring piece 310 is located between the needle holder 420 and the first housing 110, and the center needle 410, the cylindrical conductor 320, and the second housing 210 are coaxially arranged, with the cylindrical conductor 320 located between the center needle 410 and the second housing 210. This coaxial arrangement improves the accuracy of the connection between the needle holder 420 and the center needle 410, and between the spring piece 310 and the cylindrical conductor 320, avoiding difficulties or poor contact when the male end 100 and the female end 200 are connected.

[0067] Reference Figure 5In this embodiment of the invention, the side wall of the insertion hole 421 of the needle holder 420 is provided with a notch 422. By providing the notch 422, the side wall of the insertion hole 421 also has a certain elasticity. By setting the inner diameter of the insertion hole 421 to be the same as or slightly smaller than the outer diameter of the central needle 410, the area around the insertion hole 421 can elastically deform when the central needle 410 is inserted into the needle holder 420, thereby improving the tightness of the contact between the central needle 410 and the needle holder 420. Specifically, two, three, or four notches 422 can be provided, as long as the functional requirements are met, and no limitation is made here.

[0068] In one embodiment, the male end 100 further includes a first circuit board 120, which is fixed inside the first housing 110. The center pin 410 and the cylindrical conductor 320 are electrically connected to the first circuit board 120, respectively; and / or,

[0069] The female end 200 also includes a second circuit board 220, which is fixed inside the second housing 210. The pin seat 420 and the spring piece 310 are electrically connected to the second circuit board 220 respectively.

[0070] Reference Figure 3 In an embodiment of this utility model, the male end 100 further includes a first circuit board 120, a pin holder 420 and a spring 310, which are electrically connected to the first circuit board 120. Both the spring 310 and the pin holder 420 are directly connected to the first circuit board 120, improving the reliability of the electrical connection. Specifically, two springs 310 are disposed on both sides of the pin holder 420.

[0071] Reference Figure 5 In an embodiment of this utility model, the female end 200 further includes a second circuit board 220. The center pin 410 and the cylindrical conductor 320 are electrically connected to the second circuit board 220, respectively. Both the cylindrical conductor 320 and the center pin 410 are directly connected to the second circuit board 220, improving the reliability of the electrical connection. Specifically, two pins are provided at one end of the cylindrical conductor 320 near the second circuit board 220. The two pins are located on both sides of the center pin 410, and the cylindrical conductor 320 is connected to the second circuit board 220 through the two pins.

[0072] In one embodiment, the electrical connector further includes a locking structure disposed between the first housing 110 and the second housing 210, for preventing the first housing 110 from separating from the second housing 210 along its own axial direction.

[0073] In embodiments of this utility model, the electrical connector further includes a locking structure. The locking structure can take the form of a snap, magnetic attraction, threaded engagement, etc., to prevent the first housing 110 and the second housing 210 from moving along the axial direction, thereby preventing the separation of the first housing 110 and the second housing 210, which in turn prevents the male end 100 from separating from the female end 200, thus improving the stability of the connection between the male end 100 and the female end 200.

[0074] In one embodiment, the locking structure includes an undercut groove 111 and a locking protrusion 211. The undercut groove 111 is disposed on the outer wall of the first housing 110, and the locking protrusion 211 is disposed on the inner wall of the second housing 210. The undercut groove 111 includes a guide groove 1111 and a locking groove 1112 that are connected to each other. The guide groove 1111 extends obliquely from one end of the first housing 110 near the second housing 210 to the other end. The locking groove 1112 extends circumferentially along the first housing 110. The locking protrusion 211 enters the locking groove 1112 through the guide groove 1111 to prevent the first housing 110 from separating from the second housing 210 along its own axial direction.

[0075] Reference Figure 2 and Figure 4 In an embodiment of this utility model, the locking structure includes an undercut groove 111 and a locking protrusion 211. The locking protrusion 211 is disposed on the inner wall of the second housing 210. The undercut groove 111 includes a guide groove 1111 and a locking groove 1112. The guide groove 1111 is inclinedly disposed on the outer wall of the first housing 110. The locking groove 1112 communicates with the guide groove 1111 and extends along the circumference of the first housing 110. When the first housing 110 is inserted into the second housing 210, the locking protrusion 211 will insert into the guide groove 1111, and the first housing 110 will continue to extend axially into the second housing 210. At time 10, due to the restriction of the guide groove 1111, the first housing 110 and the second housing 210 need to rotate relative to each other at a certain angle until the locking protrusion 211 slides into the locking groove 1112. The first housing 110 can no longer extend into the second housing 210. At this time, the first housing 110 and the second housing 210 continue to rotate relative to each other, so that the locking protrusion 211 enters the locking groove 1112. The locking protrusion 211 is restricted by the locking groove 1112 and cannot move along the axial direction of the first housing 110, which makes it impossible for the first housing 110 and the second housing 210 to separate axially. The axial locking of the first housing 110 and the second housing 210 is achieved by the cooperation of the undercut groove 111 and the locking protrusion 211, which further improves the stability of the connection between the male end 100 and the female end 200, so that the electrical connector can effectively resist separation caused by external force or vibration, and improve the reliability of the electrical connector.

[0076] In one embodiment, the locking structure further includes an elastic ring 500. The outer wall of the first housing 110 is provided with a limiting protrusion. The elastic ring 500 is sleeved on the outside of the first housing 110 and is located on the side of the limiting protrusion facing the second housing 210. The locking protrusion 211 enters the locking groove 1112, so that the second housing 210 and the limiting protrusion squeeze and deform the elastic ring 500, so that the elastic ring 500 generates an elastic force along its own axis.

[0077] Combination Figure 1 and Figure 2 In this embodiment of the present invention, a limiting protrusion is provided on the outer wall of the first housing 110, and an elastic ring 500 is provided on the side of the limiting protrusion facing the second housing 210. When the locking protrusion 211 enters the locking groove 1112, that is, when the first housing 110 and the second housing 210 are axially fixed relative to each other, the locking protrusion 211 and the second housing 210 squeeze and deform the elastic ring 500. The elastic force generated by the elastic ring 500 acts on the first housing 110 and the second housing 210 on both sides, increasing the radial normal pressure between the inner wall of the locking groove 1112 and the locking protrusion 211, which also increases the static friction between the inner wall of the locking groove 1112 and the locking protrusion 211, making it difficult for the locking protrusion 211 to slide relative to the locking groove 1112, and making it difficult for the locking protrusion 211 to exit the undercut groove 111. This makes the connection between the male end 100 and the female end 200 more stable, and enables the male end 100 and the female end 200 to more effectively resist separation caused by external force or vibration.
