Description

Title of the invention: coaxial connector technical field

[0001] The technology described herein relates to coaxial connectors. PREVIOUS ART

[0002] JP 2019-153464A describes an example of a coaxial connector that includes an outer housing (“housing”) in which a terminal receiving chamber (“terminal receiving portion”) is formed to receive a jack (“terminal”) connected to a terminal of a coaxial cable, and a clip attached to the outer housing to engage with (i.e., retain) the jack in the terminal receiving chamber. The jack has a circular rim (“collar portion”) projecting circumferentially outward from the outer contact, the outer housing has a housing lancet that retains the circular rim of the received terminal in the terminal receiving chamber, and the clip has engagement claws (“support portion”) that are formed so as to be insertable into engagement holes (“clip insertion holes”) formed in the outer housing and serve to retain the collar portion.

[0003] JP 2019-153464A is an example of related art. Summary of the invention

[0004] Problem to be solved by the invention.

[0005] For example, in a coaxial connector used in a location where external force is applied to the cable during use, such as in a vehicle door, the terminal in the terminal-receiving portion of the housing can be inadvertently rotated, causing the terminal contacts to rub against each other and become worn. To prevent this, some housings are equipped with a stop ("whirlwind stop") to prevent the terminal from rotating. Coaxial connectors in which a stop is attached to the housing, in addition to a fastener that retains and holds the terminal in the normal position, require more parts and assembly steps. Furthermore, the formation of multiple insertion holes in the housing can reduce the connector's strength and also reduces the degree of freedom in the connector's design.

[0006] The technology described herein has been completed in view of the situation described above, and an object of this description is to provide a coaxial connector with a simple configuration that can hold the terminal in the normal position in the terminal receiving portion while preventing rotation of the terminal.

[0007] Solution to the problem.

[0008] A coaxial connector described herein comprises: a housing having a terminal receiving portion into which a terminal connected to a coaxial cable is insertable from the rear; and a fastener configured to be fixed to the housing, in which the terminal comprises: a crimped portion crimped to have a polygonal cross-sectional shape, and a collar portion situated in front of the crimped portion in a direction of insertion of the terminal when the terminal has been inserted into the terminal receiving portion, the collar portion projecting circumferentially outwards beyond the crimped portion, the housing having a fastener insertion hole which passes through a wall of the terminal receiving portion in a direction intersecting the direction of insertion of the terminal,The fastener comprises: an adjustment portion configured to fit around the crimped portion of the terminal, including at least one corner of the crimped portion in a fixed state in which the terminal has been received in the terminal receiving portion in a normal position and the fastener has been inserted into the fastener insertion hole and secured in an engagement position; a bearing portion configured to bear against the collar portion of the terminal from behind in the fixed state; and a recess formed between the adjustment portion and the bearing portion to move the adjustment portion back towards an outer circumferential face of the terminal in the fixed state.

[0022] METHODS OF IMPLEMENTING THE INVENTION

[0023] Description of embodiments.

[0024] First, embodiments of this description will be listed and described.

[0025] (1) A coaxial connector of the present description comprises: a housing comprising a terminal receiving portion into which a terminal connected to a coaxial cable is insertable from the rear; and a fastener configured to be attached to the housing, in which the terminal comprises: a crimped portion, crimped to have a polygonal cross-sectional shape, and a collar portion situated in front of the crimped portion in a direction of insertion of the terminal when the terminal has been inserted into the terminal receiving portion, the collar portion projecting circumferentially outwards beyond the crimped portion, the housing comprises a fastener insertion hole which passes through a wall of the terminal receiving portion in a direction intersecting the direction of insertion of the terminal,The fastener comprises: an adjustment portion configured to fit around the crimped portion of the terminal, including at least one corner of the crimped portion in a fixed state in which the terminal has been received in the terminal receiving portion in a normal position and the fastener has been inserted into the fastener insertion hole and secured in an engagement position; a bearing portion configured to bear against the collar portion of the terminal from behind in the fixed state; and a recess formed between the adjustment portion and the bearing portion to move the adjustment portion back towards an outer circumferential face of the terminal in the fixed state.

[0026] According to the configuration described in section (1) above, rotation of the terminal is prevented because the adjustment portion acts as a vortex stop, and the terminal cannot slide backward because the support portion acts as a retaining portion. Since the fastener includes both the adjustment portion and the support portion, it is possible to prevent the terminal from rotating and sliding simply by securing the fastener. It should be noted that, in a terminal in which a crimped portion is formed by crimping terminal fittings installed around the coaxial cable to the rear of the collar portion, an incomplete crimped portion is formed which has a larger diameter than the crimped portion.In this regard, since the aforementioned configuration has the hollow between the support portion and the adjustment portion of the fastener, and the hollow serves as a relief for the incomplete crimped portion, the adjustment portion can adjust around the crimped portion without interfering with the incomplete crimped portion. Consequently, due to its simple configuration, the coaxial connector can hold the terminal in the normal position in the terminal receiving portion while preventing rotation of the terminal.

[0027] (2) In the coaxial connector of this description, the attachment comprises preferably an inclined portion formed on one end of the attachment insertion of the support portion, the inclined portion being inclined backwards while extending in a direction in which the attachment is inserted.

[0028] When the fastener is inserted through the fastener insertion hole with the terminal partially inserted behind its normal position in the terminal receiving portion, the insertion end of the support portion initially rests against the radially projecting collar portion. According to the configuration described in section (2) above, since the rearward-angled portion is provided on this end, if the fastener is pushed further in, the collar portion is pressed forward by the angled portion to move the terminal forward from its normal position. In this way, simply by placing the fastener in the engagement position, the terminal can be moved from the partially inserted position to the normal position for receipt in the housing.

[0029] (3) In the coaxial connector of this description, preferably, the attachment has a structure that is symmetrical around a central longitudinal plane when the attachment is fixed to the housing.

[0030] In accordance with the aforementioned coaxial connector described in section (3) above, work efficiency is improved since the fastener can be attached without considering its front and rear orientation. Furthermore, since the fastener can be used in either male or female coaxial connector to receive the male and female terminals, respectively, which are connected end-to-end, common parts can be used to facilitate part control.

[0031] Detailed description of embodiments.

[0032] Embodiments of this description will be described below. The present invention is not limited by these examples, but is rather indicated by the accompanying claims, and all changes in the claims and their meaning and range of equivalence are intended to be covered within the scope of the invention.

[0033] <Modes de réalisation > .

[0034] Embodiments of the present invention will be described below with reference to [Fig. 1] to 11.

[0035] In this description, the side of the coaxial connector opposite the partner coaxial connector, in other words the left side of the coaxial connector shown in [Fig. 3], will be referred to hereafter as the front (the opposite side is the rear). In the description For convenience, the upper side in [Fig. 3] is considered the top side (the opposite side is considered the bottom side); however, coaxial connectors and connector structures can be used in any position. The description of the fastener is based on its position when the fastener is attached to the housing. The direction in which the fastener is inserted into the housing (downward) will sometimes be referred to as the insertion direction. Some or all of the X, Y, and Z axes of the XYZ Cartesian coordinate system are shown in portions of the drawings, with the exception of [Fig. 4] and [Fig. 5], and the axis directions are the same in all drawings. The Z-axis direction indicates the vertical direction, the Y-axis direction indicates the longitudinal direction, and the X-axis direction indicates the lateral direction.Where there is a plurality of identical elements, one of the identical elements may be indicated by a reference symbol while this indication may be omitted for the rest of the elements.

[0036] Connector structure.

[0037] Figures 1 and 2 show a connector structure 100 comprising a coaxial connector 1 according to the present embodiment. The connector structure 100 comprises a male coaxial connector 1 for receiving a male T100 terminal connected to a terminal of a coaxial cable C1, and a female coaxial connector 2 for receiving a female T200 terminal connected to a terminal of a coaxial cable C2. As shown in Figure 2, the male coaxial connector 1 comprises a male housing 10 having a cylindrical cap 13 projecting forward and a fastener 50 attached to the housing 10. Furthermore, the female coaxial connector 2 comprises a female housing 20 having a corresponding cylinder at the front into which the cap portion 13 is inserted, and a fastener 50 attached to the housing 20.Although not shown in the drawings, the 100 connector structure further includes a male frame that holds the male coaxial connector 1 and a female frame that holds the female coaxial connector 2, and the locking structures provided on the male and female frames can maintain the plugging between the two coaxial cable connectors 1 and 2.

[0038] As shown in [Fig. 2], in the connector structure 100, the fastener 50 attached to the male housing 10 has the same structure as the fastener 50 attached to the female housing 20, allowing the use of common parts. The following description will focus primarily on the male coaxial connector 1.

[0039] Housing.

[0040] Figure 3 is a partially cutaway side view of the coaxial connector 1. As shown in Figures 2 and 3, the housing 10 of the coaxial connector 1 has the approximately cylindrical cap portion 13 projecting forward from the front surface of a male-side main body 11 formed as an approximately rectangular parallelepiped. The housing 10 may consist, for example, of a The insulating synthetic resin is formed in one piece. As shown in [Fig. 3], the housing 10 has a terminal receiving portion 15 formed within it, through which the main male-side body 11 and the cap portion 13 penetrate in the longitudinal direction. The terminal T100, connected to the coaxial cable terminal Cl, is inserted from behind and received in the terminal receiving portion 15.

[0041] As shown in [Fig. 3] for example, a lancet 17 is provided on the underside of the main body on the male side 11 and formed with a cantilever shape with a free front end so that the lancet can bend and protrude, in its natural state, in the vertical direction into the terminal receiving portion 15. A fastener insertion hole 19 is formed in the surface of the top of the main body on the male side 11 and penetrates the upper wall of the terminal receiving portion 15. Formed laterally to the fastener insertion hole 19 in the main body on the male side 11 are a pair of fastener engagement holes 18 penetrating the left and right walls of the terminal receiving portion 15 ([Fig. 10]).

[0042] Coaxial cable.

[0043] Coaxial cables C1 and C2, for example, have an inner conductor, a dielectric surrounding the inner conductor, an outer conductor made of braided wire and other materials surrounding the dielectric, and an insulator covering the outer conductor. The coaxial terminal connected to the coaxial cable has, for example, a center contact connected to the inner conductor, an insulator holding the center contact, an outer contact holding the insulator, and a metal sleeve crimped to the outer conductor.

[0044] Terminal.

[0045] Figure 4 shows the male T100 terminal received in coaxial connector 1, and the [Fig.5] shows the female T200 terminal received in coaxial connector 2.

[0046] Terminal T100 (T200) comprises a crimped portion T11 (T211) crimped to the coaxial cable Cl (C2) at its proximal end, a cylindrical distal portion T121 (T221) connected at its distal end to the partner terminal, and a collar portion T131 (T231) located in front of the crimped portion T111 (T211) and projecting circumferentially from it. Provided between the collar portion T131 (T231) and the distal portion T121 (T221) is a forward collar portion T132 (T232) projecting so as to have approximately the same diameter as the collar portion T131 (T231).

[0047] The distal portion T221 of the female T200 terminal is formed to fit substantially closely around the distal portion T121 of the male T100 terminal. When coaxial connector 1, which receives the male T100 terminal in the normal position, and coaxial connector 2, which receives the female T200 terminal in the normal position, are fitted together, the distal portion T121 of the male T100 terminal is inserted into the distal portion T221 of the female terminal T200, bringing, for example, the central contacts held in the distal portions T121 and T221 into contact with each other to electrically connect the two terminals T100 and T200.

[0048] The crimped portion Tl 11 (T211) is crimped to the coaxial cable Cl (C2) by installing terminal fittings around the outer periphery of the terminating coaxial cable Cl (C2) and then crimping the terminal fittings to the rear of the collar portion T131 (T231) so as to have a polygonal cross-sectional shape. This embodiment shows an example in which the portion Tl 11 (T211) is crimped to form a hexagon in cross-section. In this embodiment, the portion Tl 11 crimped to the male terminal T100 and the portion T211 crimped to the female terminal T200 have the same external shape.

[0049] If the crimped portion Tl 11 (T211) is crimped as described above, it is difficult to crimp the section all the way to the boundary with the collar portion T131 (T231). Therefore, as shown in [Fig.4] ([Fig.5]), an incomplete crimped portion T141 (T241) whose diameter is smaller than that of the collar portion T131 (T231) but larger than that of the crimped portion Tl 11 (T211) is formed in the terminal T100 (T200) between the collar portion T131 (T231) and the crimped portion Tl 11 (T211).

[0050] Attachment.

[0051] Figures 6 to 8 show the fasteners 50 attached to the male housing 10 and the female housing 20. The white arrows in Figures 6 to 8 indicate the direction in which the fasteners 50 are inserted. As shown, for example, in [Fig. 6], the fastener 50 comprises a main body 51 and a pair of legs 53 branching downwards from the main body 51 in the direction of insertion of the fastener 50, i.e. downwards, a pair of flexibly deformable arms 55 formed at the left and right sides of the main body 51 in the form of a cantilever with a free lower end, and a pair of stop portions 57 projecting laterally outwards from the main body 51 below the lower ends of the arms 55. Formed at the free lower end of each arm 55 is a gripping claw 55A which projects laterally outwards from it. As shown in [Fig.7] For example, the top surface of each 55A plugging claw is substantially horizontal, and the bottom surface is an inclined surface extending outwards while extending upwards.

[0052] As shown in [Fig. 8] for example, the main body 51, the lugs 53 and the retaining portions 57 are formed to provide an approximately aligned front surface. This front surface constitutes a bearing portion 50A which, when the fastener 50 is fixed in the engagement position as described above, bears against the rear surface of the collar portion T131 of the terminal T100 in the normal position (see [Fig. 9B]).

[0053] As shown in Figures 6 and 7, between the tabs 53 on the underside, or insertion side, of the fastener 50, there is a fitting portion 53A shaped to fit substantially closely around the crimped portion T11, which includes at least one corner thereof. As shown in Figures 6 and 8, the front side of the fitting portion 53A is cut to form a recess 53B such that the fitting portion 53A moves backward toward the outer circumferential surface of the terminal T100 when the fitting portion 53A is fitted around the crimped portion T11. The recess 53B is formed with a longitudinal dimension that is approximately equal to, or slightly greater than, the distance from the rear surface of the collar portion T131 to the front end of the crimped portion T11.The depth dimension of the hollow 53B is greater than the height of the outer circumferential surface of the portion Tl 11 crimped to the outer circumferential surface of the incomplete crimped portion T141, and approximately equal to or less than the height of the outer circumferential surface of the portion Tl 11 crimped to the outer circumferential surface of the collar portion T131. Furthermore, as shown in [Fig. 6] and [Fig. 8], the front surface of the protruding end of each leg 53, i.e. the insertion end of the support portion 50A, has an inclined portion 53C formed on it which is inclined backwards while extending downwards.

[0054] The fastener 50 has a structure that is symmetrical about the longitudinal central plane P shown in [Fig. 8]. In other words, the rear surface of the fastener 50 has the same shape as its front surface shown in [Fig. 7].

[0055] Fastening of the attachment.

[0056] The following describes how the fastener 50 is fixed to the housing 10 in the engagement position with reference to [Fig.9A] to 11.

[0057] Figure 9A shows how the fastener 50 is inserted through the fastener insertion hole 19 when the terminal T100, inserted from behind into the terminal receiving portion 15, is in a partially inserted position where it has not yet reached its normal position. In this state, the lancet 17 on the underside of the housing 10 rests on the collar portion T131 and is curved downwards. As indicated by the empty arrow in [Fig.9A], the fastener 50 is inserted downwards, legs 53 first, while keeping the front bearing portion 50A on the front open edge of the fastener insertion hole 19. Since the protruding ends of the legs 53 enter the terminal receiving portion 15, the inclined portions 53C formed on the front surfaces of the protruding ends of the legs 53 come to rest on the rear corner of the collar portion T131 of the terminal T100, which is at this time in the partially inserted position.If the fastener 50 continues to be pushed inwards to move the fastener 50 downwards, the inclined portions 53C press the collar portion T131 forwards, putting the terminal T100 into the normal position as indicated by the black arrow in [Fig.9A].

[0058] As shown in [Fig. 9B], when the fastener 50 is pushed downwards and fixed in the engagement position, the collar portion T131 moves forward of the front end of the lancet 17, and the lancet 17 is released from the loading force and returned to its position behind the collar portion T131, thus preventing rearward movement of the collar portion T131, and therefore of the terminal T100. At the same time, since the bearing portion 50A on the front face of the fastener 50 bears against the rear surface of the collar portion T131, the bearing portion 50A acts as a retaining portion to doubly ensure that rearward movement of the terminal T100 is prevented.

[0059] As shown in [Fig. 10], the engagement position refers to the position of the fastener 50 in which the retaining portions 57 are pushed inward until they bear against the lower open edges of the respective fastener engagement holes 18. When the fastener 50 is pushed into the engagement position, the arms 55, having passed through the fastener insertion hole 19 while bending and deforming toward the central axis, regain their shape with the upper surfaces of the engagement claws 55A bearing against the upper open edges of the fastener engagement holes 19. Consequently, the fastener 50 cannot slide upward and engages with the housing 10.

[0060] Fig. 11 is a partially enlarged view of the vicinity of the fastener 50 fixed in the engagement position as shown in Fig. 3. As shown in Figs. 10 and 11, when the fastener 50 is fixed in the engagement position, the adjustment portion 53A, formed on the underside of the fastener between the tabs 53, is fitted substantially tightly around the crimped portion T11 of the terminal T100. The adjustment portion 53A, by being fitted around the crimped portion Tl 11 having at least one of its corners, serves as a vortex stop (or stop) to prevent rotation of the terminal T100 when an external force is applied to the coaxial cable CL

[0061] At this moment, as shown in [Fig.1 1], the hollow 53B of the fastener 50 is positioned opposite the incomplete crimped portion T141 formed between the collar portion T131 and the crimped portion Tl 11 of the terminal T100.Since the recess 53B serves as a relief for the incomplete crimped portion T141, the fastener 50 can be pushed into the engagement position for fastening without causing interference between the incomplete crimped portion T141 and the adjustment portion 53A.

[0062] Effects of the embodiment.

[0063] The effects of this embodiment will be described below.

[0064] The coaxial connector 1 of this embodiment comprises the housing 10 having the terminal receiving portion 15 supplied therein into which the T100 terminal connected to the coaxial cable Cl is inserted from behind, and the fastener 50 fixed to the housing 10. The T100 terminal has the crimped portion Tl 11, crimped to form a circular shape The polygonal conferential portion, and the collar portion T131 located in front of the crimped portion T11 when the terminal T100 is inserted into the terminal receiving portion 15, the collar portion formed to project circumferentially outwards beyond the crimped portion T11. The housing 10 has a fastener insertion hole 19 which passes through a wall of the terminal receiving portion 15 in a direction intersecting the direction in which the terminal T100 is inserted.The fastener includes an adjustment portion 53A fitted around the crimped portion Tl 11 of the terminal T100 having at least one corner of the crimped portion Tl 11 when the terminal T100 is received in the normal position in the terminal receiving portion 15 and the fastener 50 is inserted through the fastener insertion hole 19 and fixed in an engagement position, the support portion 50A bearing on the collar portion T131 of the terminal T100 from behind when the terminal T100 is in the normal position and the fastener 50 is in the engagement position, and the hollow 53B formed between the adjustment portion 53A and the support portion 50A to move the adjustment portion 53A back towards the outer circumferential surface of the terminal T100 when the terminal T100 is in the normal position and the fastener is in the engagement position. .

[0065] According to coaxial connector 1 of this embodiment, rotation of terminal T100 is prevented because the adjustment portion 53A acts as a vortex stop, and terminal T100 cannot slide backward because the support portion 50A acts as a retaining portion. Since the clip 50 comprises both the adjustment portion 53A and the support portion 50A, terminal T100 can be prevented from rotating and sliding simply by securing the clip 50. It should be noted that, in a terminal in which a crimped portion T11 is formed by crimping terminal fittings installed around the coaxial cable Cl to the rear of the collar portion T131, the crimping is performed by progressively reducing the crimping stress on the coaxial cable Cl toward the boundary with the collar portion T131 in order to prevent breakage of the cable in the crimped portion T11.Therefore, an incomplete crimped portion T141 (also known as a flare) with a larger diameter than the crimped portion Tl 11 is formed between the collar portion T131 and the crimped portion Tl 11. In this respect, since the aforementioned configuration has the recess 53B between the support portion 50A and the adjustment portion 53A of the fastener 50, and the recess 53B serves as a relief for the incomplete crimped portion T141, the adjustment portion 53A can fit around the crimped portion Tl 11 while avoiding interference with the incomplete crimped portion T141. Consequently, the simply configured coaxial connector 1 is provided, which can hold the terminal T100 in the normal position in the terminal receiving portion 15 while preventing rotation of the terminal T100.

[0066] Moreover, in the coaxial connector 1 of the present embodiment, the attachment 50 includes the legs 53 bifurcating downwards in the direction of insertion of the fastener 50 towards the housing 10. In addition, the support portion 50A is formed on the front surface of the legs 53, the adjustment portion 53A is formed on the insertion side of the fastener between the legs 53, and the front side of the adjustment portion 53A is cut to form a hollow 53B such that the front side of the adjustment portion 53A recedes towards the circumference of the terminal T100.

[0067] Furthermore, in the coaxial connector 1 of the present embodiment, the fastener 50 has inclined portions 53C formed on the fastener insertion end of the support portion 50A, the inclined portions 53C being inclined backwards in the direction in which the fastener is inserted.

[0068] When the fastener 50 is inserted through the fastener insertion hole 19 with the terminal T100 in a partially inserted position behind its normal position, the insertion end of the support portion 50A initially rests against the radially projecting collar portion T131. According to the coaxial connector 1 of this embodiment, since the rearward-angled portions 53C are provided on this end, if the fastener 50 is pushed further in, the collar portion T131 is pressed forward by the angled portions 53C to move the terminal T100 forward relative to its normal position. In this way, simply by placing the fastener 50 in the plugging position, the terminal T100 can be moved from the partially inserted position to the normal position to be received in the housing.

[0069] Moreover, in the coaxial connector 1 of the present embodiment, the fastener 50 has a structure that is symmetrical around the longitudinal central plane P when the fastener 50 is fixed to the housing 10.

[0070] In accordance with the aforementioned coaxial connector 1, working efficiency is improved since the fastener 50 can be attached without regard to its front and rear orientation. Furthermore, since the fastener 50 can be used in either of the male and female coaxial connectors 1 and 2 to receive the male T100 terminal and the female T200 terminal, respectively, which are connected end-to-end, common parts can be used to facilitate control of the components.

[0071] Other embodiments.

[0072] This description is not limited to the embodiment described in connection with the aforementioned description and drawings. For example, the following embodiments also fall within the technical scope described in the present invention.

[0073] (1) Although the coaxial connector of the aforementioned embodiment is described as receiving a terminal, the present invention is not limited to that. In a coaxial connector that receives a plurality of terminals and to which a fastener is attached, it It is possible to prevent the terminals from being turned inadvertently or from slipping by equipping the attachment with a plurality of support portions (retaining portions), a plurality of adjustment portions (vortex stops) and a plurality of hollows (raised portions).

[0074] (2) The housing described in the aforementioned embodiment is only one example, and it can be formed differently from the above. The coaxial connectors of the present invention are not limited to those with connector structures having male and female connectors.
