[0002] Cochlear implants are currently recognized worldwide as the only effective device and method to restore hearing for patients with bilateral severe or profound sensorineural hearing loss. It is one of the miracles of modern medicine. Cochlear implants aim to help patients with profound hearing loss restore their hearing and language communication abilities. It is a rapidly developing new technology for deaf rehabilitation in recent years. After receiving a cochlear implant, patients with severe hearing and speech impairments can say goodbye to sign language and lip reading through speech rehabilitation training, and can communicate with others through hearing and speech like normal people, integrating into their families and society.

[0003] Currently, the transmitting coil and transmitting cable of existing cochlear implant external units are often integrated. This means that if the transmitting cable is damaged, the transmitting coil must also be repaired or replaced when the transmitting cable is repaired or replaced. Similarly, if the transmitting coil is damaged, the transmitting cable must also be repaired or replaced when the transmitting coil is repaired or replaced, resulting in high maintenance costs. Summary of the Invention

[0004] In view of the shortcomings of the prior art described above, the purpose of this utility model is to provide a cochlear implant external unit connection structure and a cochlear implant, so as to solve the problem of high maintenance cost of the integrated cochlear implant external unit in the prior art.

[0005] To achieve the above and other related objectives, one aspect of this utility model provides an external cochlear implant connection structure, including a connector, the connector comprising a connector female and a connector male, the first end of the connector female being pluggable to the first end of the connector male, and the connector female and connector male being electrically connected after connection; a transmitting coil electrically connected to the connector female; a transmitting cable electrically connected to the connector male; and a housing, the connector female and the transmitting coil being disposed within the housing.

[0006] Furthermore, the female connector includes a female connector body and a ferrule disposed within the female connector body.

The male connector includes a male connector body and a male connector terminal disposed within the male connector body. A first end of the male connector body has a insertion portion, and a first end of the male connector terminal is located within the insertion portion and has a insertion hole. A second end of the male connector terminal protrudes from a second end of the male connector body. The transmitting coil is connected to the second end of the ferrule, and the transmitting cable is connected to the second end of the male connector terminal.

[0007] Furthermore, a snap-fit ​​flange is provided on the outer peripheral surface of the insertion part, and the snap-fit ​​flange is interference-fitted with the insertion groove.

[0008] Furthermore, the snap-fit ​​flange and the insertion groove are made of plastic, and the hardness of the snap-fit ​​flange is less than that of the insertion groove.

[0009] Furthermore, a groove is provided on one side of the housing, and the groove is located on the same side as the female connector; the transmitting cable includes a plug and a cable electrically connected to the plug, the second end of the male connector is disposed inside the plug and electrically connected to the plug, and a protrusion adapted to the groove is provided on the plug.

[0010] Furthermore, the housing is provided with a pin hole that communicates with the groove, and the protrusion is also provided with a pin hole. A positioning pin is embedded in the pin hole on the housing and the pin hole on the protrusion.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0046] Please see Figures 1 to 5 It should be noted that the illustrations provided in this embodiment are only schematic representations of the basic concept of this utility model. Therefore, the drawings only show the components related to this utility model and are not drawn according to the actual number, shape and size of the components. In actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0047] The first aspect of this utility model provides an external cochlear implant connection structure (hereinafter referred to as the "connection structure"), such as... Figures 1 to 5 As shown, the connection structure includes a connector, a transmitting coil 20, a transmitting cable 30, and a housing 40. The connector includes a female connector 11 and a male connector 12. The first end of the female connector 11 is plugged into and detached from the first end of the male connector 12, and the female connector 11 and the male connector 12 are electrically connected after being connected. The transmitting coil 20 is electrically connected to the female connector 11, and the female connector 11 and the transmitting coil 20 are disposed inside the housing 40. The transmitting cable 30 is electrically connected to the male connector 12.

[0048] The beneficial effects of the external cochlear implant connection structure of this utility model are as follows: The external cochlear implant connection structure connects the cochlear implant's transmitting coil 20 and transmitting cable 30 through a connector, that is, the transmitting coil 20 is electrically connected to the connector female socket 11 of the connector, and the transmitting cable 30 is electrically connected to the connector male connector 12 of the connector. Moreover, the connector male connector 12 and the connector female socket 11 can be plugged and unplugged. Therefore, when the transmitting cable 30 is damaged, the connector male connector 12 can be pulled out from the connector female socket 11 to separate the transmitting cable 30 from the transmitting coil 20, so that the transmitting cable 30 can be replaced or repaired separately. Similarly, the transmitting coil 20 can also be replaced or repaired separately, thereby greatly reducing costs.

[0049] Furthermore, such as Figure 5As shown, in this embodiment, the female connector 11 includes a female connector body 110 and a ferrule 111 disposed within the female connector body 110. The first end of the female connector body 110 is provided with a insertion groove 1101, and the first end of the ferrule 111 is located within the insertion groove 1101. The second end of the ferrule 111 protrudes from the second end of the female connector body 110. The male connector 12 includes a male connector body 120 and a male connector terminal 121 disposed within the male connector body 120. The first end of the male connector body 120 is provided with a insertion portion 1201, and the first end of the male connector terminal 121 is located within the insertion portion 1201. The first end of the male connector terminal 121 is provided with a socket, and the second end of the male connector terminal 121 protrudes from the second end of the male connector body 120. Specifically, the transmitting coil 20 is connected to the second end of the ferrule 111, and the transmitting cable 30 is connected to the second end of the male connector terminal 121. Specifically, the circuit board of the transmitting coil 20 is soldered to the second end of the ferrule 111. In this structural design, when the connector female socket 11 and the connector male connector 12 are inserted, the insertion portion 1201 at the first end of the male connector body 120 is inserted into the insertion slot 1101 of the female socket body 110, and the first end of the ferrule 111 located in the insertion slot 1101 is inserted into the socket on the male terminal 121 located in the insertion portion 1201. Electrical conduction is achieved through the insertion contact between the ferrule 111 and the male terminal 121. Furthermore, the insertion portion 1201 on the male connector body 120, inserted into the insertion slot 1101 on the female socket body 110, provides protection, ensuring the stability and safety of the insertion between the ferrule 111 and the male terminal 121. Specifically, in this embodiment, there are four ferrules 111 and four male terminals 121.

[0050] Furthermore, to improve the stability and sealing of the connection between the connector female 11 and the connector male 12, preferably, such as Figure 5 As shown, in this embodiment, a snap-fit ​​flange 1202 is provided on the outer peripheral surface of the plug portion 1201. The snap-fit ​​flange 1202 is interference-fitted with the plug groove 1101 at the first end of the female body 110, thereby ensuring that the connection between the connector female body 11 and the connector male head 12 will not easily come off, and also achieving good sealing and waterproofing.

[0051] Furthermore, preferably, in this embodiment, both the snap-fit ​​flange 1202 and the insertion groove 1101 are made of plastic, and the hardness of the snap-fit ​​flange 1202 is less than the hardness of the insertion groove 1101. With this configuration, when the male connector 12 is inserted into the female connector 11, because the hardness of the snap-fit ​​flange 1202 is less than the hardness of the insertion groove 1101, it is easier to insert the snap-fit ​​flange 1202 into the insertion groove 1101. The tight fit between the snap-fit ​​flange 1202 and the inner wall of the insertion groove 1101 also improves the sealing performance at the insertion point of the female connector 11 and the male connector 12, resulting in better waterproofing.

[0052] To further improve the stability of the mating connection between the connector female 11 and the connector male 12, and to prevent reverse insertion, preferably, as follows: Figure 2 and Figure 4 As shown, in this embodiment, a groove 401 is provided on one side of the housing 40, and the groove 401 is located on the same side as the connector female 11. That is, the opening of the groove 401 is located on the same side as the opening of the insertion groove 1101 at the first end of the female body, and they face the same direction. Correspondingly, the transmitting cable 30 includes a plug 31 and a cable 32 electrically connected to the plug. The second end of the connector male 12 is disposed in the plug 31 and electrically connected to the plug 31, and a protrusion 310 adapted to the groove 401 is provided on the plug 31. With this structural design, when the connector female socket 11 and the connector male plug 12 are plugged in, when the plug portion 1201 at the first end of the male plug body 120 is inserted into the plug groove 1101 of the female socket body 110, the protrusion 310 on the plug 31 will be inserted into the groove 401 on the housing 40 accordingly. Therefore, through the limiting effect of the protrusion 310 and the groove 401, the connection between the connector female socket 11 and the connector male plug 12 can be prevented from becoming loose. Moreover, when the plug is inserted in the wrong direction, the plug portion 1201 cannot be inserted into the plug groove 1101 of the female socket body 110, so as not to damage the connector female socket and the connector male plug, which has a strong foolproof effect.

[0053] Furthermore, such as Figure 1 , Figure 2 and Figure 4 As shown, in this embodiment, a pin hole 402 is provided on the housing 40, which communicates with the groove 401. Correspondingly, a pin hole 402 is also provided on the protrusion 310. A positioning pin 403 is embedded in the pin hole on the housing and the pin hole on the protrusion. This arrangement positions the protrusion 310 on the plug 31 within the groove 401 on the housing 40 by the positioning pin 403. This makes it difficult for the plug 31 to be inserted out of the housing 40, effectively preventing the male connector 12 from becoming loose from the female connector 11, and ensuring the stability and reliability of the connection between the female connector 11 and the male connector 12. Specifically, in this embodiment, the positioning pin 403 has a slight clearance fit with the pin hole 402, allowing the positioning pin 403 to be easily inserted into the pin hole 402 without falling out.

[0054] Specifically, such as Figure 4 As shown, in this embodiment, the second end of the male connector 12 is integrally formed with the plug 31 through injection molding, resulting in a simple structure and strong stability.

[0055] Specifically, such as Figure 1 and Figure 2As shown, in this embodiment, the housing 40 includes an upper housing 41 and a lower housing 42, which are detachably connected. This arrangement facilitates the later maintenance and replacement of the transmitting coil 20 and the connector socket 11 located inside the housing. Specifically, in this embodiment, the upper and lower housings are snap-fitted together, resulting in a simple structure and easy disassembly. Of course, in other optional embodiments, the upper and lower housings can also be connected by adhesive or screws, etc.

[0056] Another aspect of this utility model provides a cochlear implant, which includes the above-described external cochlear implant connection structure and implant body.

[0057] The beneficial effects of this cochlear implant are the same as those of the aforementioned external cochlear implant connection structure, so they will not be repeated here.

[0058] In summary, the external cochlear implant connection structure and cochlear implant of this invention allow for the replacement or repair of the transmitting cable or transmitting coil independently, thereby significantly reducing costs. Therefore, this invention effectively overcomes the various shortcomings of existing technologies and possesses high industrial applicability.

[0059] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
