Description

Technical Field

[0001] The present invention relates to a connector for connecting to electronic devices and the like, and a connector capable of providing a stable electrical connection to electronic devices and the like. Background Technology

[0002] In connectors used for connecting to electronic devices, such as those used for connecting to shooting devices, it is very important to ensure a stable electrical connection between the shooting device and the connector in order to reliably transmit and receive shooting signals (electrical signals) generated by the shooting device.

[0003] As such a connector for connecting to electronic devices, there is a known external connection connector 13 that is provided on the housing 5 of the shooting device 1 and electrically connected to the shooting device 1 (for example, see Patent Document 1).

[0004] The external connection connector 13 includes a shielding member 16 that serves as a conductor and a cylindrical contact piece 22 that slides against the shielding member 16 under the force applied by a helical spring 23. Furthermore, the cylindrical contact piece 22 includes a sliding contact 22a and an annular contact 22b.

[0005] The sliding contact 22a is electrically connected to the shielding member 16 and is engaged with the anti-disengagement locking part 16c of the shielding member 16. Furthermore, the annular contact 22a makes conductive contact with the substrate 10 inside the imaging device 1. In this way, the imaging device 1 is electrically connected to the external connection connector 13.

[0006] However, the sliding contact 22a of the external connector 13 is frequently subjected to a certain load generated by the force applied by the helical spring 23. Furthermore, the lifespan of the imaging device 1 is typically long, and therefore the use of the external connector 13 on the imaging device 1 is also typically long. As a result, the sliding contact 22a of the external connector 13 may deform due to years of deterioration. If the sliding contact 22a deforms, the electrical connection between the imaging device 1 and the external connector 13 via the cylindrical contact piece 22 may become unstable.

[0009] Patent Document 1: Japanese Patent Application Publication No. 2018-107097 Summary of the Invention

[0010] The problem that the invention aims to solve

[0011] This invention was made to solve such a problem, and its purpose is to provide a connector that can stably connect to electronic devices and the like.

[0012] Solution for solving the problem

[0013] To achieve the above objectives, the connector of the present invention is configured to include: a housing body made of a conductive material; a center contact member disposed along the central axis of the housing body, the front end of the center contact member contacting a contact portion of a target electronic device; an insulating member disposed between the housing body and the center contact member, holding the center contact member in place; a movable housing axially movable along the central axis, the movable housing slidingly contacting the housing body and engaging with a fitting portion of the target electronic device; and a spring, one end fixed to the housing body, the other end contacting the movable housing and extending towards the housing body. The spring is located inside the main body of the housing and applies force to the movable housing on the mating side; and a cover member is formed with a cover through hole for the movable housing to pass through and is fixed to the main body of the housing. The main body of the housing has: an inner cylindrical portion that accommodates the center contact member and the insulating member; and an outer cylindrical portion located outside the inner cylindrical portion, forming a space between the outer cylindrical portion and the inner cylindrical portion to accommodate the spring. The movable housing has: an elastic contact portion that slides in contact with the inner cylindrical portion; and a flange portion that is subjected to force by the spring. The cover member has a cover support portion that supports the flange portion.

[0014] According to this structure, in the connector of the present invention, the elastic contact portion of the movable housing slides in contact with the inner cylindrical portion of the housing body, thereby electrically connecting the movable housing and the housing body. Furthermore, the movable housing engages with the mating portion of the target electronic device, thus electrically connecting the movable housing and the target electronic device. Additionally, the central contact contacts the contact portion of the target electronic device, thus electrically connecting the central contact to the target electronic device. Therefore, the connector and the target electronic device are electrically connected via the movable housing and the central contact.

[0015] Furthermore, when the connector engages with the mating portion of the electronic device on the target side, the movable housing slides against the housing body while moving axially along the central axis, thereby absorbing any axial positional shift of the movable housing relative to the target electronic device. Additionally, the spring applies force to the flange portion, thereby ensuring contact pressure between the movable housing and the target electronic device when they are engaged.

[0016] Furthermore, the force applied by the spring is borne by the flange portion of the movable housing rather than the elastic contact portion. Thus, the elastic contact portion and the flange portion respectively undertake the following two functions of the movable housing: (1) the function of electrical connection achieved through sliding contact with the housing body and (2) the function of bearing the load generated by the applied force of the spring. Therefore, the load generated by the applied force of the spring is not applied to the elastic contact portion that slides in contact with the housing body. Therefore, even with long-term use of the connector, the elastic contact portion will not deform due to the applied force of the spring, and the function of electrical connection achieved through sliding contact between the elastic contact portion and the housing body will not be impaired. Therefore, the connector of the present invention can stably connect to the target electronic device.

[0017] The connector of the present invention is configured to include: a housing body made of a conductive material; a center contact member disposed along the central axis of the housing body, the front end of the center contact member contacting a contact portion of an object electronic device; an insulating member disposed between the housing body and the center contact member, holding the center contact member; a movable housing capable of axial movement along the central axis, the movable housing slidingly contacting the housing body and engaging with a fitting portion of the object electronic device; a stop member having a stop member through hole for insertion of the movable housing member, and capable of sliding along the central axis with the inner circumferential surface of the housing body; a spring having one end fixed to the housing body and the other end contacting the stop member and applying force to the stop member toward the fitting portion, the spring being disposed inside the housing body; and a cover member, shaped as... The cover has a through hole for the movable housing to pass through and is fixed to the housing body. The housing body has: an inner cylindrical portion for accommodating the center contact member and the insulating member; and an outer cylindrical portion disposed outside the inner cylindrical portion, forming a space between the outer cylindrical portion and the inner cylindrical portion for accommodating the spring. The stop member has: a spring bearing portion for bearing the applied force of the spring; and a sliding upright wall that is axially erected on the central axis in a manner that allows it to slide against the inner circumferential surface of the outer cylindrical portion. The movable housing has: an elastic contact portion that slides in contact with the inner cylindrical portion; and a flange portion that is forceped by the spring via the stop member. By supporting the stop member with the flange portion, the movable housing and the stop member can move together along the central axis. The cover member has a cover support portion that supports the flange portion.

[0018] According to this structure, in the connector of the present invention, the elastic contact portion of the movable housing slides in contact with the inner cylindrical portion of the housing body, thereby electrically connecting the movable housing and the housing body. Furthermore, the movable housing engages with the mating portion of the target electronic device, thus electrically connecting the movable housing and the target electronic device. Additionally, the center contact contacts the contact portion of the target electronic device, thus electrically connecting the center contact to the target electronic device. Therefore, the connector and the target electronic device are electrically connected via the movable housing and the center contact.

[0019] Furthermore, when the connector engages with the mating portion of the electronic device on the target side, the movable housing slides against the housing body while moving axially along the central axis, thereby absorbing any axial positional shift of the movable housing relative to the target electronic device. Additionally, the spring applies force to the flange portion, thereby ensuring contact pressure between the movable housing and the target electronic device when they are engaged.

[0020] Furthermore, the force applied by the spring is borne by the spring-bearing portion of the stop member, rather than by the elastic contact portion of the movable housing. Therefore, even with prolonged use of the connector, the elastic contact portion will not deform due to the force applied by the spring, and the electrical connection function achieved by the sliding contact between the elastic contact portion and the housing body will not be impaired. Therefore, the connector of the present invention can achieve a stable electrical connection with the target electronic device.

[0021] Furthermore, when using the connector, if the spring is offset horizontally relative to the central axis, the contact pressure of the spring on the movable housing via the stop decreases, resulting in insufficient electrical connection between the movable housing and the target electronic device. Consequently, the electrical connection between the connector and the target electronic device becomes unstable.

[0022] However, the connector of the present invention has a sliding wall provided when the stop is erected, which suppresses the spring from shifting horizontally relative to the central axis, thus enabling a more stable electrical connection with the target electronic device.

[0023] Furthermore, a through-hole is formed in the stop member, allowing the elastic contact portion of the movable housing to slide in contact with the inner cylinder portion at a position higher than the stop member. This ensures sufficient height of the space between the inner and outer cylinder portions for accommodating the spring, thus guaranteeing the contact pressure of the spring on the movable housing via the stop member. Consequently, the electrical connection between the movable housing and the target electronic device is sufficient, ensuring a stable electrical connection between the connector and the target electronic device.

[0024] In the connector with the above structure, it can also be configured such that the elastic contact portion is inserted through the through hole of the stop member and contacts the inner cylindrical portion.

[0025] According to this structure, in the connector of the present invention, the elastic contact portion of the movable housing is inserted into the through hole of the stop member, and the elastic contact portion contacts the inner cylinder portion, thereby causing the area for accommodating the spring and the area for moving the elastic contact portion in the axial direction of the central shaft to overlap, thereby ensuring the height of the spring is adequately accommodated, and obtaining stable elasticity by extending the length of the elastic contact portion, thereby enabling a stable electrical connection between the housing body and the movable housing.

[0026] In the connector with the above structure, it can also be configured such that: the outer cylindrical portion has a small diameter portion and a large diameter portion with different outer diameters, and the sliding vertical wall is configured to slide with the inner circumferential surface of the large diameter portion, whose outer diameter is larger than that of the small diameter portion.

[0027] According to this structure, in the connector of the present invention, the housing body has a large-diameter portion that can slide against the sliding upright. By providing a large-diameter portion in the housing body in this way, the radial width of the sliding upright can be sufficiently obtained, and the lateral offset of the spring, i.e., the axial offset of the spring relative to the central axis in the horizontal direction, can be reliably suppressed.

[0028] In the connector with the above structure, it can also be configured such that: the cover member has a stepped portion with a recessed height around the cover through hole, and the cover support portion is formed in the stepped portion.

[0029] According to this structure, the connector of the present invention, by providing a stepped portion with a recessed height in the cover member, can sufficiently ensure the height of the space for accommodating the spring formed between the inner and outer cylindrical portions, thus ensuring the contact pressure of the spring on the movable housing via the stop member. Therefore, the electrical connection between the movable housing and the target electronic device is sufficient, and the electrical connection between the connector and the target electronic device is stable.

[0030] In the connector with the above structure, the housing body is configured such that it has a protruding piece that protrudes toward the bottom surface of the stepped portion at a position lower than the housing flange formed at the lower end of the outer cylindrical portion.

[0031] According to this structure, the connector of the present invention can prevent the end of the flange portion of the movable housing from contacting the stepped portion of the cover member, and can move the cover member and the stop member to the bottom surface side of the stepped portion where the cover support portion is formed.

[0032] In the connector with the above structure, the cover member is configured to have one or more cutouts.

[0033] According to this structure, when the connector of the present invention fixes the housing body to an external electronic device, it can utilize the space vacated by the cutout portion to easily fix the housing body to the external electronic device using a fixing member.

Detailed Implementation

[0053] (First Implementation)

[0054] The following is for reference Figures 1 to 7 The connector 100 of this embodiment will now be described. First, the structure of the connector 100 will be described.

Furthermore, Figure 4 It is connector 100. Figure 1 A cross-sectional view of section AA in the middle. Figure 1 The XY plane direction is called the horizontal direction, and the Z-axis direction is called the axial direction. Figure 2 The same applies below. Sometimes the positive side of the Z-axis is called the top, and the negative side of the Z-axis is called the bottom.

[0056] (Connector)

[0057] like Figure 1 , Figure 2 , Figure 3 As shown, connector 100 includes a housing body 101, terminals 150, an insulator 151, a movable housing 120, a spring 152, and a cover member 140. Connector 100, as described later, is mounted on a camera device 160, which is an electronic device, and connected to an external cable connector 163, thereby electrically connecting the camera device 160 and the external cable connector 163 via connector 100. Examples of electronic devices that can be mounted on connector 100 include camera devices, industrial robots, medical devices, smartphones, tablets, etc., but are not limited to these devices and can also be other electronic devices. Connector 100 is a so-called floating connector that uses a spring to allow the movable part to move in order to absorb axial positional misalignment with the mating object, thus enabling a secure mating regardless of the position.

[0058] (Main body of the shell)

[0059] The housing body 101 is made of a conductive material and has a cylindrical portion. The housing body 101 is made of zinc die casting, but can also be other metals such as brass. The housing body 101 has an inner cylindrical portion 102, an outer cylindrical portion 103, a first housing flange 106, and a second housing flange 107. Figure 2 , Figure 3 As shown, the housing body 101 has two flange portions on the outer side and a double cylindrical structure on the inner and outer sides. The housing body 101 constitutes the housing body of the present invention.

[0060] like Figure 4 As shown, the inner cylindrical portion 102 has an internal receiving space S1 that accommodates the terminal 150 and the insulator 151. The inner cylindrical portion 102 has an upper portion 102a for connecting to the outside of the cable connector 163, and a lower portion 102b located inside the outer cylindrical portion 103 and sliding against the movable housing 120 described later. Thus, the inner cylindrical portion 102 slides against the movable housing 120 by providing the lower portion 102b. The inner cylindrical portion 102 is inserted into the movable housing body 121 of the movable housing 120.

[0061] The outer cylindrical portion 103 is located outside the lower side portion 102b of the inner cylindrical portion 102, and a receiving space S2 is formed between the outer cylindrical portion 103 and the lower side portion 102b to serve as a space for accommodating the spring.

[0062] The first housing flange 106 is a circular plate-shaped member located at the lower end of the outer cylindrical portion 103, with a diameter larger than the outer diameter of the outer cylindrical portion 103. The first housing flange 106 has riveting portions 109a, 109b, and 109c, and housing flange holes 110a, 110b, and 110c. In this embodiment, three riveting portions and three housing flange holes are provided, but the number is not limited to these. The first housing flange 106 is the portion for fixing the cover member 140.

[0063] Riveting portions 109a, 109b, and 109c are components provided on the lower surface side of the first housing flange 106 for riveting and fixing the cover member 140. More specifically, the riveting portions 109a, 109b, and 109c are riveted through fixing holes 144a, 144c, and 144e of the cover member 140 to perform riveting, thereby fixing the cover member 140. Housing flange holes 110a, 110b, and 110c are holes used when fixing the first housing flange 106 to electronic devices or the like using riveting or fastening components such as bolts.

[0064] The second housing flange 107 is a circular plate-shaped member located at the upper end of the outer cylindrical portion 103, which is larger in diameter than the outer diameter of the upper side portion 102a of the inner cylindrical portion 102.

[0065] (Movable shell)

[0066] The movable housing 120 is movable along the axial direction (Z-axis direction) of the central axis of the housing body 101. The movable housing 120 slides in contact with the housing body 101 and engages with the fitting portion 161a of the imaging device 160 described later. The movable housing 120 constitutes the movable housing of the present invention.

[0067] The movable housing 120 has a cylindrical movable housing body 121, elastic contact portions 122a, 122b, 122c, and 122d, and flange portions 123a, 123b, 123c, and 123d. The movable housing 120 is made of zinc die casting, but other metals such as brass can also be used. In this embodiment, four elastic contact portions and four flange portions are provided, but this number is not required.

[0068] like Figure 2 , Figure 3 As shown, the movable housing body 121 is the cylindrical portion of the movable housing 120. The outer diameter of the movable housing body 121 is larger than the outer diameter of the inner cylindrical portion 102, allowing the inner cylindrical portion 102 to be inserted into the interior of the movable housing body 121. Furthermore, the outer diameter of the movable housing body 121 is smaller than the outer diameter of the cover through hole 142, allowing the movable housing body 121 to be inserted into the inside of the cover through hole 142. The movable housing body 121 can engage with the fitting portion 161a of the socket 161 provided in the imaging device 160, as described later. Because the movable housing body 121 engages with the fitting portion 161a of the imaging device 160, the movable housing 120 is electrically connected to the imaging device 160.

[0069] The elastic contact portions 122a, 122b, 122c, and 122d slide in contact with the outer peripheral surface of the lower side portion 102b of the inner cylindrical portion 102. In this way, the elastic contact portions 122a, 122b, 122c, and 122d slide in contact with the outer peripheral surface of the lower side portion 102b of the housing body 101, thereby electrically connecting the movable housing 120 to the housing body 101. The flange portions 123a, 123b, 123c, and 123d are exerted downward force by the spring 152 and are supported by the cover support portion of the cover member. The flange portions 123a, 123b, 123c, and 123d of the movable housing 120 are exerted force by the spring 152, thereby ensuring the contact pressure of the movable housing 120 on the imaging device 160 when the movable housing 120 is engaged with the imaging device 160.

[0070] In this embodiment, the movable housing 120 uses flanges 123a, 123b, 123c, 123d instead of elastic contacts 122a, 122b, 122c, 122d to bear the force applied by the spring 152. Therefore, the load generated by the force applied by the spring 152 is not applied to the elastic contacts 122a, 122b, 122c, 122d, and the electrical connection function achieved by the sliding contact between the elastic contacts 122a, 122b, 122c, 122d and the housing body 101 is not impaired. That is, the movable housing 120 effectively shares the functions of (1) the electrical connection function achieved by the sliding contact with the housing body 101 and (2) the load function generated by the force applied by the spring 152 with the elastic contacts 122a, 122b, 122c, 122d and the flanges 123a, 123b, 123c, 123d, respectively.

[0071] Furthermore, when the connector 100 is engaged with the socket 161 of the shooting device 160, the movable housing 120 slides in contact with the housing body 101 while moving along the Z-axis direction, thereby absorbing the positional offset of the movable housing 120 relative to the Z-axis direction of the shooting device 160.

[0072] (Cover component)

[0073] The cover member 140 has a cover through hole 142 through which the movable housing 120 is inserted, and is fixed to the first housing flange 106 of the housing body 101. The cover member 140 has a cover support portion 141, a cover through hole 142, and fixing holes 144a, 144b, 144c, 144d, 144e, and 144f. The material of the cover member 140 may be, for example, SUS (stainless steel), but may also be other metals. The cover member 140 constitutes the cover member of the present invention.

[0074] The cover support portion 141 supports the flange portions 123a, 123b, 123c, and 123d from below. The cover support portion 141 is the area around the cover through hole 142 that supports the flange portions 123a, 123b, 123c, and 123d, and therefore the area of ​​the cover support portion 141 varies according to the dimensions of the flange portions 123a, 123b, 123c, and 123d.

[0075] The through hole 142 is a through hole formed in the center of the cover member 140, through which the movable housing body 121 of the movable housing 120 is inserted. The through hole 142 is a circular through hole, but it can also be other shapes that match the shape of the movable housing 120.

[0076] The fixing holes 144a, 144b, 144c, 144d, 144e, and 144f are six holes formed at approximately equal intervals outside the cover through hole 142. In this embodiment, six fixing holes are formed, but the number is not limited to this. The fixing holes 144a, 144c, and 144e are used when the cover member 140 is riveted and fixed to the housing body 101 via the riveting portions 109a, 109b, and 109c of the housing body 101. Furthermore, the fixing holes 144b, 144d, and 144f are used when the cover member 140 and the first housing flange 106 are fixed to the imaging device 160 using riveting or bolts, based on alignment with the housing flange holes 110a, 110b, and 110c.

[0077] (terminal)

[0078] like Figure 4 As shown, terminal 150 is arranged along the central axis of housing body 101, and the front end portion 150a of terminal 150 contacts the contact portion 161b of imaging device 160. Terminal 150 is held by insulator 151 and engages with an engaging portion of insulator 151 (not shown at this time). Terminal 150 is made of copper alloy, but other metals may also be used. Terminal 150 constitutes the central contact of the present invention.

[0079] The front end portion 150a of terminal 150 contacts the contact portion 161b of the socket 161 provided in the shooting device 160. Furthermore, the rear end portion 150b of terminal 150 contacts an external cable connector 163. Thus, because the front end portion 150a of terminal 150 contacts the contact portion 161b of the socket 161, terminal 150 is electrically connected to the shooting device 160. Furthermore, because the rear end portion 150b of terminal 150 contacts the external cable connector 163, terminal 150 is electrically connected to the cable connector 163.

[0080] (Insulator)

[0081] An insulator 151 is located between the housing body 101 and the terminal 150, holding the terminal 150. The insulator 151 is made of a resin such as polyamide, which serves as an insulating member, but is not limited to this. The insulator 151 is housed in a receiving space S1 inside the inner cylindrical portion 102 of the housing body 101. The insulator 151 constitutes the insulating member of the present invention.

[0082] (spring)

[0083] Spring 152 is disposed inside housing body 101. One end 152a of spring 152 is fixed to housing body 101, and the other end 152b contacts movable housing 120 and applies force to movable housing 120 towards the fitting portion 161a of socket 161. One end 152a is held by a protrusion or the like of housing body 101 (not shown). Spring 152 is made of materials such as SUS, but may also be other metals such as copper alloy. Spring 152 constitutes the spring of the present invention.

[0084] Spring 152 is housed within the receiving space S2 formed between the outer cylindrical portion 103 and the inner cylindrical portion 102. Spring 152 applies force to the flange portions 123a, 123b, 123c, and 123d of movable housing 120 on the side of fitting portion 161a. The force applied by spring 152 ensures the contact pressure of movable housing 120 with socket 161, and the electrical connection between movable housing 120 and imaging device 160 is sufficient.

[0085] (Example of application of the shooting device)

[0086] An example of applying the connector 100 described above to the imaging device 160 will be described.

[0087] Figure 5 This is a schematic diagram showing the connector 100, the imaging device 160, and the cable connector 163. The imaging device 160 includes a socket 161 and a base plate 162. The socket 161 has a fitting portion 161a that fits into the movable housing body 121 and a contact portion 161b that contacts the terminal 150. The socket 161 is mounted on the base plate 162. The imaging device 160 constitutes the electronic device subject to this invention.

[0088] The cable connector 163 is fitted into the upper part 102a of the housing body 101 and contacts the rear end part 150b of the terminal 150. Thus, the terminal 150 is electrically connected to the cable connector 163, and the electrical signal of the imaging device 160 is transmitted to the cable connector 163 via the connector 100.

[0089] Figure 6 The diagram shows the state in which the movable housing body 121 of the movable housing 120 of the connector 100 is engaged with the mating portion 161a of the socket 161, and the terminal 150 is in contact with the contact portion 161b. In this state, the cover support portion 141 of the cover member 140 is supported by contacting the flange portions 123a, 123b, 123c, and 123d. The contact pressure of the movable housing 120 on the socket 161 is almost negligible.

[0090] Figure 7 Showing from Figure 6The connector 100 is pressed downwards as a whole. In this state, the front end portion 150a of the terminal 150 is pressed into the contact portion 161b and makes stronger contact with the contact portion 161b. In addition, the spring 152 is compressed, and the force exerted by the spring 152 on the flange portions 123a, 123b, 123c, and 123d increases, which can sufficiently ensure the contact pressure of the movable housing 120 on the socket 161. The movable housing 120, which is not yet fixed to the housing body 101, is still in a state of... Figure 6 In the middle position, the flange portions 123a, 123b, 123c, and 123d are separated from the cover support portion 141.

[0091] As described above, the connector 100 of this embodiment includes: a housing body 101 made of a conductive material; a terminal 150 disposed along the central axis of the housing body 101, the front end portion 150a of the terminal 150 contacting the contact portion 161b of the imaging device 160; an insulator 151 located between the housing body 101 and the terminal 150, holding the terminal 150; a movable housing 120 axially movable along the central axis, the movable housing 120 slidingly contacting the housing body 101 and engaging with the fitting portion 161a of the imaging device 160; a spring 152, one end 152a fixed to the housing body 101, the other end 152b contacting the movable housing 120 and applying force to the movable housing 120 toward the fitting portion 161a, the spring 152 being disposed inside the housing body 101; and a cover member 140 having a cover through hole 142 for the movable housing 120 to pass through, and fixed to the housing body 101. Furthermore, the housing body 101 has: an inner cylindrical portion 102 that accommodates the terminal 150 and the insulator 151 in a accommodating space S1; and an outer cylindrical portion 103 located outside the inner cylindrical portion 102, forming a accommodating space S2 for accommodating the spring 152 between the outer cylindrical portion 103 and the inner cylindrical portion 102. The movable housing 120 has: elastic contact portions 122a, 122b, 122c, and 122d that slide in contact with the inner cylindrical portion 102; and flange portions 123a, 123b, 123c, and 123d that are subjected to force by the spring 152. The cover member 140 has a cover support portion 141 that supports the flange portions 123a, 123b, 123c, and 123d.

[0092] According to this structure, in the connector 100 of this embodiment, the elastic contact portions 122a, 122b, 122c, and 122d of the movable housing 120 slide in contact with the inner cylindrical portion 102 of the housing body 101, thereby electrically connecting the movable housing 120 to the housing body 101. Furthermore, the movable housing 120 engages with the fitting portion 161a of the imaging device 160, thus electrically connecting the movable housing 120 to the imaging device 160. Additionally, the terminal 150 contacts the contact portion 161b of the imaging device 160, thus electrically connecting the terminal 150 to the imaging device 160. Therefore, the connector 100 and the imaging device 160 are electrically connected via the movable housing 120 and the terminal 150.

[0093] Furthermore, when the connector 100 is engaged with the fitting portion 161a of the imaging device 160, the movable housing 120 slides in contact with the housing body 101 while moving axially along the central axis, thereby absorbing the axial positional displacement of the movable housing 120 relative to the imaging device 160. Additionally, the spring 152 applies force to the flange portions 123a, 123b, 123c, and 123d, thereby ensuring the contact pressure of the movable housing 120 on the imaging device 160 when the movable housing 120 is engaged with the imaging device 160.

[0094] Furthermore, the force applied by the spring 152 is borne by the flange portions 123a, 123b, 123c, 123d of the movable housing 120, rather than by the elastic contact portions 122a, 122b, 122c, 122d of the movable housing 120. Thus, the elastic contact portions 122a, 122b, 122c, 122d and the flange portions 123a, 123b, 123c, 123d respectively share the following two functions of the movable housing 120: (1) the function of electrical connection achieved through sliding contact with the housing body 101 and (2) the function of bearing the load generated by the force applied by the spring 152. Therefore, the load generated by the force applied by the spring 152 is not applied to the elastic contact portions 122a, 122b, 122c, 122d that slide in contact with the housing body 101. Therefore, even with prolonged use of the connector 100, the elastic contacts 122a, 122b, 122c, and 122d will not deform due to the force applied by the spring 152, and the electrical connection function achieved by the sliding contact between the elastic contacts 122a, 122b, 122c, and 122d and the housing body 101 will not be impaired. Therefore, the connector 100 of this embodiment can achieve a stable electrical connection with the imaging device 160.

[0095] (Second Implementation)

[0096] The main structure of the connector 200 in this embodiment is the same as that in the first embodiment described above. Therefore, in the following description, the same markings are used for structures that are the same as those in the first embodiment, and the descriptions are omitted. Refer to Figures 8-11 The differences from the first embodiment will be explained, particularly the stop 230 and the outer cylindrical portion 203 of the housing body 201.

[0097] Figure 8 This is a perspective view showing the connector 200 of this embodiment. Figure 9 This is a perspective view showing the stop member 230 of the connector 200 used in this embodiment. Furthermore, Figure 10 It is connector 200. Figure 8 A cross-sectional view of section AA in the middle.

[0098] (Stop component)

[0099] The connector 200 of this embodiment includes a stop member 230. The stop member 230 has a stop member through hole 233 through which the movable housing 120 passes, and can slide against the inner circumferential surface of the housing body 201 in the Z-axis direction, which is the central axis. The stop member 230 has a sliding vertical wall 231, a spring receiving portion 232, and a stop member through hole 233. The stop member 230 is made of a resin such as polyamide as an insulating member, but is not limited to this. The stop member 230 constitutes the stop member of the present invention.

[0100] The sliding wall 231 is configured to slide against the inner circumferential surface 205a of the large-diameter portion 205 of the outer cylindrical portion 203, and is erected on the outer edge of the housing body 201 in the Z-axis direction, which is the central axis. By erecting the sliding wall 231, the spring 152 is prevented from shifting horizontally relative to the Z-axis direction, thus enabling a more stable electrical connection with the imaging device 160.

[0101] The spring bearing portion 232, which bears the force applied by the spring 152, is formed around the stop through hole 233 with a step at a lower position inside the sliding wall 231. The spring bearing portion 232 is forcefully applied to the mating portion 161a by the other end 152b of the spring 152. The stop 230, including the spring bearing portion 232, is supported from below by flanges 123a, 123b, 123c, and 123d. Therefore, the spring 152 applies force to the flanges 123a, 123b, 123c, and 123d via the spring bearing portion 232. The stop 230 can withstand the force applied by the spring 152 and move along the Z-axis direction, which is the central axis of the housing body 201, together with the movable housing 120.

[0102] In this way, the force applied by the spring 152 is borne by the spring bearing portion 232 rather than the elastic contact portions 122a, 122b, 122c, and 122d. Therefore, the elastic contact portions 122a, 122b, 122c, and 122d will not deform due to the force applied by the spring 152, and the electrical connection function achieved by the sliding contact between the elastic contact portions 122a, 122b, 122c, and 122d and the housing body 201 will not be impaired.

[0103] The stop through hole 233 is a through hole through which the elastic contact portions 122a, 122b, 122c, and 122d of the movable housing 120 are inserted. That is, the inner diameter of the stop through hole 233 is larger than the outer diameter of the elastic contact portions 122a, 122b, 122c, and 122d of the movable housing 120. The stop through hole 233 is a circular through hole, but it can also be other shapes that match the shapes of the elastic contact portions 122a, 122b, 122c, and 122d of the movable housing 120.

[0104] In this way, the elastic contact portions 122a, 122b, 122c, and 122d of the movable housing 120 are inserted into the through hole 233 of the stop member, and the elastic contact portions 122a, 122b, 122c, and 122d contact the inner cylinder portion 202, thereby causing the area of ​​the space S2 for accommodating the spring 152 in the Z-axis direction to overlap with the area of ​​the space S2 for moving the elastic contact portions 122a, 122b, 122c, and 122d. This ensures that the height of the spring 152 is adequately accommodated, and by extending the length of the elastic contact portions 122a, 122b, 122c, and 122d, stable elasticity can be obtained.

[0105] By forming a stop through hole 233 in the stop 230, the elastic contact portions 122a, 122b, 122c, and 122d of the movable housing 120 can slide in contact with the inner cylinder portion 202 at a position higher than the stop 230. Therefore, the height of the receiving space S2 for the spring 152 formed between the inner cylinder portion 202 and the outer cylinder portion 203 can be sufficiently ensured, thus ensuring the contact pressure of the spring 152 on the movable housing 120 via the stop 230.

[0106] (Main body of the shell)

[0107] The outer cylindrical portion 203 of the housing body 201 has a small-diameter portion 204 and a large-diameter portion 205 with different outer diameters. The outer diameter of the large-diameter portion 205 is configured to be larger than the outer diameter of the small-diameter portion 204. The inner circumferential surface 205a of the large-diameter portion 205 is a surface that can slide with the sliding vertical wall 231. The housing body 201 constitutes the housing body of the present invention.

[0108] A third housing flange 208 is formed on the outer peripheral surface of the outer cylindrical portion 203 at the boundary between the small diameter portion 204 and the large diameter portion 205. A stepped surface 210 is formed on the inner peripheral surface of the outer cylindrical portion 203 at the boundary between the small diameter portion 204 and the large diameter portion 205. The stepped surface 210 is located above the sliding wall 231, and when an unexpected large load is applied to compress the spring 152, the upward movement of the stop 230 can be locked at the position of the stepped surface 210. By providing the large diameter portion 205 in the housing body 201 in this way, the radial width of the sliding wall 231 can be sufficiently obtained, and the lateral displacement of the spring 152, that is, the horizontal displacement of the spring 152 relative to the Z-axis direction, can be reliably suppressed.

[0109] (Example of application of the shooting device)

[0110] An example of applying the connector 200 described above to the imaging device 160 will be described.

[0111] Figure 11 The diagram shows the state in which the connector 100 is pressed downwards from a state where the movable housing body 121 of the movable housing 120 of the connector 200 is engaged with the mating portion 161a of the socket 161 and the terminal 150 contacts the contact portion 161b. In this state, the front end portion 150a of the terminal 150 is pressed into the contact portion 161b and makes stronger contact with the contact portion 161b. Furthermore, the spring 152 is compressed, and the force exerted by the spring 152 on the flange portions 123a, 123b, 123c, and 123d increases, which sufficiently ensures the contact pressure of the movable housing 120 on the socket 161. The movable housing 120, which is not yet fixed to the housing body 201, does not move with the housing body 201, so the flange portions 123a, 123b, 123c, and 123d are separated from the cover support portion 141.

[0112] As described above, the connector 200 of this embodiment includes: a housing body 201 made of a conductive material; a terminal 150 disposed along the central axis of the housing body 201, the front end portion 150a of the terminal 150 contacting the contact portion 161b of the imaging device 160; an insulator 151 disposed between the housing body 201 and the terminal 150, holding the terminal 150; and a movable housing 120 axially movable along the central axis, the movable housing 120 slidingly contacting the housing body 201 and engaging with the fitting portion 161a of the imaging device 160. The components include: a stop 230 with a stop through hole 233 for the movable housing 120 to pass through, which can slide on the inner circumferential surface of the housing body 201 in the axial direction of the central axis; a spring 152 with one end 152a fixed to the housing body 201 and the other end 152b contacting the stop 230 and applying force to the stop 230 on the side of the fitting portion 161a, the spring 152 being disposed inside the housing body 201; and a cover member 140 with a cover through hole 142 for the movable housing 120 to pass through, and fixed to the housing body 201. Furthermore, the housing body 201 has: an inner cylindrical portion 202 for accommodating the terminal 150 and the insulator 151; and an outer cylindrical portion 203 disposed outside the inner cylindrical portion 202, forming a accommodating space S2 for accommodating the spring 152 between the outer cylindrical portion 203 and the inner cylindrical portion 202. The stop member 230 has: a spring bearing portion 232 for bearing the applied force of the spring 152; and a sliding upright wall 231, which is axially erected on the central axis in a manner that allows it to slide against the inner circumferential surface of the outer cylindrical portion 203. The movable housing 120 has: an elastic joint... Contacts 122a, 122b, 122c, and 122d slide in contact with the inner cylindrical portion 202; and flanges 123a, 123b, 123c, and 123d are subjected to force by spring 152 via stop 230. By the stop 230 being supported by flanges 123a, 123b, 123c, and 123d, the movable housing 120 and the stop 230 can move together axially along the central axis. The cover member 140 has a cover support portion 141 that supports flanges 123a, 123b, 123c, and 123d.

[0113] According to this structure, in addition to the effects of the connector 100 in the first embodiment, the connector 200 of this embodiment also has the following effects.

[0114] In connector 200, the force applied by spring 152 is further borne by the spring-bearing portion 232 of stop 230 rather than the elastic contact portions 122a, 122b, 122c, 122d of movable housing 120. Therefore, even with long-term use of connector 200, the elastic contact portions 122a, 122b, 122c, 122d will not deform due to the force applied by spring 152, and the electrical connection function achieved by the sliding contact between the elastic contact portions 122a, 122b, 122c, 122d and housing body 201 will not be impaired. Therefore, connector 200 of this embodiment can be stably electrically connected to imaging device 160.

[0115] Furthermore, when using connector 200, when spring 152 is offset horizontally relative to the central axis, the contact pressure of spring 152 on movable housing 120 via stop 230 decreases, and the electrical connection between movable housing 120 and shooting device 160 is insufficient. As a result, the electrical connection between connector 200 and shooting device 160 is unstable.

[0116] However, the connector 200 has a sliding wall 231 provided when the stop 230 is erected, which will suppress the spring 152 from shifting horizontally relative to the central axis, thus enabling a more stable electrical connection with the shooting device 160.

[0117] Furthermore, by forming a stop through hole 233 in the stop 230 and inserting the elastic contact portions 122a, 122b, 122c, and 122d of the movable housing into the stop through hole 233, the elastic contact portions 122a, 122b, 122c, and 122d of the movable housing 120 can slide in contact with the inner cylinder portion 202 at a position higher than the stop 230. Therefore, the height of the receiving space S2 for the receiving spring 152 formed between the inner cylinder portion 202 and the outer cylinder portion 203 can be sufficiently ensured, thus ensuring the contact pressure of the spring 152 on the movable housing 120 via the stop 230. Therefore, the electrical connection between the movable housing and the imaging device 160 is sufficient, and the electrical connection between the connector 200 and the imaging device 160 is stable.

[0118] In connector 200, the elastic contact portions 122a, 122b, 122c, and 122d are inserted into the stop member through hole 233 and contact the inner cylindrical portion 202.

[0119] According to this structure, in the connector 200, the elastic contact portions 122a, 122b, 122c, and 122d of the movable housing 120 are inserted into the through hole 233 of the stop member. The elastic contact portions 122a, 122b, 122c, and 122d contact the inner cylinder portion 202, thereby causing the area of ​​the space S2 for accommodating the spring 152 in the Z-axis direction and the area of ​​the space S2 for moving the elastic contact portions 122a, 122b, 122c, and 122d to overlap. This ensures that the height of accommodating the spring 152 is sufficiently guaranteed, and stable elasticity is obtained by extending the length of the elastic contact portions 122a, 122b, 122c, and 122d. This allows for a stable electrical connection between the housing body 201 and the movable housing 120.

[0120] Furthermore, in the connector 200, the outer cylindrical portion 203 is configured such that the outer cylindrical portion 203 has a small diameter portion 204 and a large diameter portion 205 with different outer diameters, and the sliding vertical wall 231 is configured to slide with the inner circumferential surface 205a of the large diameter portion 205, which is the inner circumferential surface of the large diameter portion 205, whose outer diameter is larger than that of the small diameter portion 204.

[0121] According to this structure, in the connector 200, the housing body 201 has a large-diameter portion 205 that slides with the sliding vertical wall 231. By providing the large-diameter portion 205 in the housing body 201 in this way, the radial width of the sliding vertical wall 231 can be sufficiently obtained, and the lateral offset of the spring 152, that is, the axial offset of the spring 152 relative to the central axis in the horizontal direction, can be reliably suppressed.

[0122] (Third implementation method)

[0123] The main structure of the connector 300 in this embodiment is the same as that in the second embodiment described above. Therefore, in the following description, the same markings are used for structures identical to those in the second embodiment, and the descriptions are omitted. Refer to Figures 12-15 The differences from the second embodiment will be explained, particularly the outer cylindrical portion 303 of the cover member 340 and the housing body 301.

[0124] Figure 12 This is a perspective view showing the connector 300 of this embodiment. Figure 13 This is a perspective view showing the cover member 340 of the connector 300 used in this embodiment. Furthermore, Figure 14 It's connector 300. Figure 12 A cross-sectional view of section AA in the middle.

[0125] (Cover component)

[0126] In this embodiment, the cover member 340 has a cover through hole 342 through which the movable housing 120 is inserted, and is fixed to the first housing flange 106 of the housing body 301. The cover member 340 has a stepped portion 341, a cover through hole 342, cover fixing surfaces 343, 344a, 344b, 344c, and cutout portions 345a, 345b, 345c. The cover member 340 differs from the cover member 140 of the first embodiment in that it has a stepped portion 341 recessed to a predetermined height around the cover through hole 342, and has three cutout portions 345a, 345b, 345c. The cover member 340 constitutes the cover member of the present invention.

[0127] The stepped portion 341 is a region recessed downwards at a predetermined height relative to the cover fixing surface 343 around the cover through hole 342. A cover support portion 341a is formed in the stepped portion 341. In this embodiment, the stepped portion 341 and the cover support portion 341a are the same region, but the cover support portion 341a may also be part of the stepped portion 341. The cover support portion 341a supports the flange portions 123a, 123b, 123c, and 123d from below. The cover support portion 341a is the region that supports the flange portions 123a, 123b, 123c, and 123d, therefore the region of the cover support portion 341a also varies depending on the dimensions of the flange portions 123a, 123b, 123c, and 123d.

[0128] The cover member 340 is provided with a stepped portion 341, which can fully ensure the height of the space S2 for accommodating the spring 152 formed between the inner cylinder portion 302 and the outer cylinder portion 303, and thus ensure the contact pressure of the spring 152 on the movable housing 120 via the stop member 230.

[0129] Furthermore, the cover member 340 is provided with a stepped portion 341, thereby shortening the distance between the force borne by the flange portions 123a, 123b, 123c, and 123d and the fulcrum. According to this principle, the rigidity of the cover support portion 341a bearing the flange portions 123a, 123b, 123c, and 123d is increased, which can prevent the cover member 340 from deforming due to the force applied by the spring 152, thereby preventing the movable housing 120 from falling off the housing body 301.

[0130] The through hole 342 is a through hole formed in the center of the cover member 340, through which the movable housing body 121 of the movable housing 120 is inserted. The through hole 342 is circular, but it can also be other shapes that match the shape of the movable housing 120.

[0131] The cover fixing surface 343 is the surface of the first housing flange 106 that is fixed to the housing body 301 when the cover member 340 is fixed to the housing body 301. The cover fixing surface 343 is formed around the downwardly recessed step portion 341 and is located above the step portion 341.

[0132] The fixing holes 344a, 344b, and 344c are three holes formed at approximately equal intervals outside the through hole 342. In this embodiment, three fixing holes are formed, but the number is not limited to this. The fixing holes 344a, 344b, and 344c are used to rivet and fix the cover member 340 to the housing body 301 through the riveting portions 109a, 109b, and 109c of the housing body 301.

[0133] Cutouts 345a, 345b, and 345c are three portions that are cut at approximately equal intervals along the outer periphery of the cover member 340. Cutouts 345a, 345b, and 345c are cut in approximately semi-circular shapes, respectively. In this embodiment, three cutouts 345a, 345b, and 345c are formed, but this number is not limited. Furthermore, the shapes of the cutouts 345a, 345b, and 345c can also be triangular or other shapes.

[0134] like Figure 12 As shown in (b), cutouts 345a, 345b, and 345c are formed in the cover member 340. Thus, when the housing body 301 is fixed to the shooting device 160, the space freed up by the cutouts 345a, 345b, and 345c can be used to easily fix the housing body 301 to the shooting device 160 using a fixing member (not shown).

[0135] (Main body of the shell)

[0136] The outer cylindrical portion 303 of the housing body 301 has an annular protruding piece 303a on the lower side of the first housing flange 106 formed at the lower end, protruding towards the bottom surface of the stepped portion 341 where the cover support portion 341a is formed. The outer periphery of the protruding piece 303a is separated from the stepped side surface 341b of the stepped portion 341 of the cover member 340 by a predetermined distance, and the lower end of the protruding piece 303a is in contact with the bottom surface of the stepped portion 341. However, it is also possible that the outer periphery of the protruding piece 303a is in contact with the stepped side surface 341b of the stepped portion 341 of the cover member 340. By providing a protruding piece 303a in the outer cylindrical portion 303, it is possible to prevent the ends of the flange portions 123a, 123b, 123c, and 123d of the movable housing 120 from contacting the stepped side surface 341b of the stepped portion 341 of the cover member 340, and to allow the cover member 340 and the stop member 230 to move to the bottom surface side of the stepped portion 341 where the cover support portion 341a is formed. The housing body 301 constitutes the housing body of the present invention.

[0137] (Example of application of the shooting device)

[0138] An example of applying the connector 300 described above to the imaging device 160 will be described.

[0139] Figure 15 The diagram shows the state in which the connector 300 is pressed downwards from a state where the movable housing body 121 of the movable housing 120 of the connector 300 is engaged with the mating portion 161a of the socket 161 and the terminal 150 contacts the contact portion 161b. In this state, the front end portion 150a of the terminal 150 is pressed into the contact portion 161b and makes stronger contact with the contact portion 161b. Furthermore, the spring 152 is compressed, and the force exerted by the spring 152 on the flange portions 123a, 123b, 123c, and 123d increases, which sufficiently ensures the contact pressure of the movable housing 120 on the socket 161. The movable housing 120, which is not yet fixed to the housing body 301, does not move with the housing body 301, so the flange portions 123a, 123b, 123c, and 123d are separated from the cover support portion 341a.

[0140] As described above, the connector 300 of this embodiment is configured such that the cover member 340 has a stepped portion 341 with a recessed height around the cover through hole 342, and the cover support portion 341a is formed on the stepped portion 341.

[0141] According to this structure, the connector 300 of this embodiment, by providing a stepped portion 341 of a predetermined height in the cover member 340, can sufficiently ensure the height of the receiving space S2 for the receiving spring 152 formed between the inner cylindrical portion 302 and the outer cylindrical portion 303, thus ensuring the contact pressure of the spring 152 on the movable housing 120 via the stop member 230. Therefore, the electrical connection between the movable housing 120 and the imaging device 160 is sufficient, and the electrical connection between the connector 300 and the imaging device 160 is stable.

[0142] In the connector 300, the housing body 301 is configured such that it has a protruding piece 303a that protrudes toward the bottom surface of the stepped portion 341, which is formed with a cover support portion 341a, at a position lower than the first housing flange 106 formed at the lower end of the outer cylindrical portion 303.

[0143] According to this structure, the connector 300 can prevent the ends of the flange portions 123a, 123b, 123c, and 123d of the movable housing 120 from contacting the stepped portion 341 of the cover member 340, and can move the cover member 340 and the stop member 230 to the bottom surface side of the stepped portion 341 where the cover support portion 341a is formed.

[0144] In connector 300, the cover member 340 is configured to have three cutouts 345a, 345b, and 345c.

[0145] According to this structure, when the connector 300 fixes the housing body 301 to the shooting device 160, it can use the space freed up by the cutouts 345a, 345b, and 345c to easily fix the housing body 301 to the shooting device 160 using a fixing member.

[0146] As described above, the connector of the present invention has the effect of providing a stable electrical connection with electronic devices, etc., and is useful for the entire connector.
