Description

Technical Field

[0001] This utility model relates to the field of fascia gun technology, and in particular to a wiring plug-in structure and its fascia gun. Background Technology

[0002] Fascia guns primarily stimulate various receptors in muscles, tendons, and joint capsules through high-frequency vibrations. Using a fascia gun to massage the human body can reduce myogenic pain, increase the pain threshold, and reduce lactic acid buildup. Massaging muscles with a fascia gun after exercise can relieve soreness and shorten muscle recovery time.

[0003] A Chinese utility model patent published on January 28, 2025, with publication number CN222399467U, describes a fascia gun with a handle extension function. By setting conductive sheets or probes in the handle, massage part, and bending extension part, and through the electrical connection structure of the conductive sheets and probes, the fascia gun can perform normal pounding massage when the handle, massage part, and bending extension part are interconnected.

[0004] However, this fascia gun uses the contact between the conductive sheet and the probe to conduct electricity, which has the following two problems: (1) When the fascia gun vibrates during operation, the conductive sheet and the probe may have poor contact, which will cause the fascia gun to be unable to work stably; (2) The contact between the conductive sheet and the probe is a point contact or a line contact, the contact area is small, the contact resistance is large, the battery of the fascia gun cannot release more power, and the impact force of the massage head is not particularly strong. Utility Model Content

[0005] To overcome the shortcomings of the existing technology, this utility model provides a wiring plug-in structure and its fascia gun to solve the problems that the conductive sheet and probe may have poor contact when the fascia gun vibrates during operation, which leads to the fascia gun not working stably, and the fascia gun's massage head has not been impacted with a particularly strong force.

[0006] To solve the above technical problems, this utility model provides the following technical solution: a wiring plug-in structure, comprising:

[0007] The female plug end has a through hole at one end along its length and a notch at the other end.

[0008] The plug has a male end, which has a plug section that can extend into a through hole, the outer diameter of the plug section being not less than the inner diameter of the through hole;

[0009] The terminal block is detachably connected to the end of the male plug that is away from the female plug. The terminal block, the male plug, and the female plug are all made of conductive material.

[0010] Preferably, the outer wall of the female plug end has a slit along its length.

[0011] Preferably, the outer wall of the female plug end is provided with several side grooves, and the outer wall of the female plug end is recessed towards the through hole to form several inner recesses, and the inner recesses are located between two side grooves.

[0012] Preferably, the male end of the plug away from the female end has a threaded hole, and a screw is provided in the threaded hole. The screw passes through the terminal block and enters the threaded hole to fix it to one end of the male end of the plug.

[0013] Preferably, the male and female terminals of the plug are made of phosphor bronze.

[0014] A fascia gun includes the aforementioned wiring and plug-in structure, and further includes a detachable and fixedly connected handle and a massage part. The massage part is provided with a transmission mechanism, and the handle part is provided with a power supply. One end of the massage part connected to the handle part is provided with a female plug / male plug, and the other end of the handle part connected to the massage part is provided with a male plug / female plug.

[0015] Preferably, it further includes at least one bent extension, with a male plug end and a female plug end respectively at both ends of the bent extension, and the male plug end and the female plug end at both ends of the bent extension are connected by a wire.

[0016] Preferably, a first fixing seat is provided at one end of the massage part and the handle part, and a second fixing seat is provided at one end of the handle part and the massage part. The two ends of the bent extension part are respectively provided with a first fixing seat and a second fixing seat. A male plug end is fixed on the first fixing seat, and a female plug end is fixed on the second fixing seat. One end of the male plug end extends out of the first fixing seat, and the end of the female plug end with a notch extends out of the second fixing seat.

[0017] Compared with the prior art, the beneficial effects that this utility model can achieve are:

[0018] This invention replaces the existing electrical connection structure of conductive sheet and probe with a plug-in type contact conductivity using female and male plug terminals. This makes the connection more stable and avoids the possibility of poor contact between the conductive sheet and probe when the fascia gun vibrates during operation, which may occur with the existing conductive sheet and probe electrical connection structure. Furthermore, replacing the existing point or line contact of conductive sheet with surface contact increases the contact area of ​​the two contacts, thereby reducing the contact resistance value. This allows the fascia gun battery to release greater power, increases the torque of the drive motor inside the fascia gun, and thus enhances the impact force of the massage head.

[0027] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model is further described below in conjunction with specific embodiments. However, the following embodiments are only preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments in the implementation methods without creative effort are all within the protection scope of this utility model.

[0028] like Figures 5-7 As shown, this utility model provides a wiring plug-in structure and its fascia gun, including: a female plug terminal 8, a male plug terminal 6, and a wiring terminal 7;

[0029] One end of the plug female terminal 8 has a through hole along its length, and the other end of the plug female terminal 8 has a notch 84. By setting the notch 84, a welding position is provided to facilitate subsequent wire bonding processes. When this wire connection structure is assembled inside the fascia gun, it can save a certain amount of space.

[0030] The male plug end 6 has a plug section that can extend into the through hole. The outer diameter of the plug section is not less than the inner diameter of the through hole. The male plug end 6 here can be formed by turning.

[0031] The terminal 7 is detachably connected to the end of the male plug 6 away from the female plug 8. The terminal 7, the male plug 6 and the female plug 8 are all made of conductive material.

[0032] By adopting a plug-in contact conductive method with female plug 8 and male plug 6, the existing electrical connection structure of conductive sheet and probe is replaced, making the connection between the two more stable. This avoids the situation where the conductive sheet and probe may have poor contact when the fascia gun vibrates during operation, which may occur with the existing electrical connection structure of conductive sheet and probe. Furthermore, the existing point contact or line contact of conductive sheet is replaced with surface contact, which increases the contact area of ​​the two contacts, thereby reducing the contact resistance value. This allows the battery of the fascia gun to release greater energy, increases the torque of the drive motor inside the fascia gun, and thus enhances the impact force of the massage head 11.

[0033] When assembling the plug-in structure into the fascia gun, the terminal 7 and the male plug 6 are detachably connected and fixed, thus avoiding the trouble of soldering the male plug 6 and the terminal 7. Considering the assembly space, the female plug 8 and another terminal 7 are soldered, which is more troublesome than the detachable fixing method, but can save some assembly space.

[0034] like Figure 7 As shown, a slit 83 is provided on the outer wall of the female plug 8 along its length. At this time, the outer diameter of the plug segment can be set to be smaller than the inner diameter of the through hole. Thus, when the plug segment of the male plug 6 is inserted into the through hole of the female plug 8, the slit 83 will expand, making the plug segment more stable in the through hole.

[0035] like Figure 7 As shown, the outer wall of the plug female end 8 is provided with several side grooves 81, and the outer wall of the plug female end 8 is recessed towards the through hole to form several inner recesses 82, and the inner recesses 82 are located between two side grooves 81.

[0036] The female plug 8 is made of sheet metal by stamping and rolling. To ensure the formation of the concave portion 82, a side groove 81 needs to be opened. By setting the concave portion 82, when the plug section of the male plug 6 is inserted into the through hole of the female plug 8, the concave portion 82 will deform as the gap 83 widens. The part of the concave portion 82 that protrudes into the through hole will abut against the male plug 6, thereby making the male plug 6 more stable in the through hole of the female plug 8.

[0037] like Figure 5 and Figure 7As shown, the male end 6 of the plug has a threaded hole 61 at the end away from the female end 8 of the plug. A screw 10 is installed in the threaded hole 61. The screw 10 passes through the terminal 7 and enters the threaded hole 61 to fix it to one end of the male end 6 of the plug. By fixing the terminal 7 to the male end 6 of the plug with the screw 10, the two can be stably fixed and can be electrically connected.

[0038] The male terminal 6 and female terminal 8 of the plug are made of phosphor bronze, which has excellent conductivity, high strength and good elasticity, thereby ensuring normal conductivity, extending service life and making the male terminal 6 and female terminal 8 easier to connect.

[0039] like Figures 2-7 As shown, a fascia gun includes a wiring plug-in structure, and also includes a detachable and fixedly connected handle part 1 and a massage part 2 (the specific detachable and fixed connection method can be one disclosed in a fascia gun with handle extension function with announcement number CN222399467U, which will not be described in detail here). The massage part 2 is provided with a transmission mechanism, which specifically includes a motor and a cam reciprocating motion structure. This is the existing structure of fascia gun movement, and the specific working principle will not be described in detail here. The output end of the transmission mechanism is connected to a massage head 11. The handle part 1 is provided with a power supply. The end of the massage part 2 connected to the handle part 1 is provided with a female plug terminal 8 / male plug terminal 6, and the end of the handle part 1 connected to the massage part 2 is provided with a male plug terminal 6 / female plug terminal 8.

[0040] Here, we will take an example where the end of the massage unit 2 connected to the handle unit 1 has a male plug terminal 6 and the end of the handle unit 1 connected to the massage unit 2 has a female plug terminal 8. When the male plug terminal 6 is inserted into the female plug terminal 8, the power supply in the handle unit 1 is electrically connected to the terminal 7 soldered on the female plug terminal 8 through the wire. After the power circuit passes through the female plug terminal 8, the male plug terminal 6, and the terminal 7 fixed on the male plug terminal 6, the terminal 7 on the male plug terminal 6 is electrically connected to the transmission mechanism in the massage unit 2 through the wire, thereby realizing the power supply and conduction of the fascia gun, so that the massage head 11 can perform impact massage.

[0041] By setting up this wiring plug-in structure, it can be ensured that when the handle 1 and massage head 2 are disassembled and re-fixed, the power supply can normally provide power for the fascia gun to work.

[0042] like Figures 1-3 As shown, it also includes at least one bent extension 3, with a male plug terminal 6 and a female plug terminal 8 at both ends of the bent extension 3, and the male plug terminal 6 and the female plug terminal 8 at both ends of the bent extension 3 are connected by a wire.

[0043] By setting the bending extension 3, the area and range of massage that the user can use the fascia gun can be effectively expanded, avoiding the inconvenience of the user not being able to use it or reach certain massage positions when massaging certain muscles. Specifically, when the bending extension 3 is assembled, the handle 1 is provided with a power supply that is electrically connected to a terminal 7 (not shown in the figure) via a wire. The terminal 7 is soldered to the female plug 8, and the female plug 8 and the male plug 6 form a wire-connected structure, which can be electrically connected. This wire-connected structure is electrically connected to another wire-connected structure via a wire in the bending extension 3. The terminal 7 of the male plug 6 of this wire-connected structure is electrically connected to the transmission mechanism in the massage part 2 via a wire, thereby ensuring that the power supply can normally provide power for the fascia gun when the bending extension 3 is added between the massage part 2 and the handle 1.

[0044] like Figures 3-7 As shown, the end of the massage part 2 connected to the handle part 1 is provided with a first fixing seat 4, and the end of the handle part 1 connected to the massage part 2 is provided with a second fixing seat 5. The two ends of the bent extension part 3 are respectively provided with a first fixing seat 4 and a second fixing seat 5. A male plug end 6 is fixed on the first fixing seat 4, and a female plug end 8 is fixed on the second fixing seat 5. One end of the male plug end 6 extends out of the first fixing seat 4 to ensure that the male plug end 6 can be inserted and fixed in the through hole of the female plug end 8. The end of the female plug end 8 with a notch 84 extends out of the second fixing seat 5 to ensure that wire soldering can be easily performed at the notch 84.

[0045] like Figure 6 and Figure 7 As shown, the second fixing base 5 has a fixing hole through which the plug female end 8 is accommodated. A slot is provided on the inner wall of the fixing hole, and an elastic buckle 85 is provided on the outer wall of the plug female end 8. When the plug female end 8 is inserted into the fixing hole, one end of the elastic buckle 85 is engaged in the slot, thereby ensuring the stable fixation between the plug female end 8 and the second fixing base 5.

[0046] like Figures 1-3 As shown, a first connecting structure 9 and a second connecting structure (not shown in the figure) are provided between the massage part 2 and the handle part 1, the handle part 1 and the bending extension part 3, and the massage part 2 and the bending extension part 3, so that they can be detachably fixed to each other. Specifically, it can be one of the fixed connecting structures disclosed in a fascia gun with handle extension function with announcement number CN222399467U, which will not be described in detail here.

[0047] like Figure 4 As shown, the first fixing base 4 can be fixed in the first connecting structure 9 by bolts, and the male end 6 of the plug will not contact the first connecting structure 9, so as not to affect the plug connection between the male end 6 and the female end 8 of the plug.

[0048] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
