FIG. 6 is a top view and a cross-sectional view, and FIG. 6 is a perspective view sequentially illustrating a process of assembling a head assembly according to an example embodiment.

  Referring to FIGS. 3 to 6, the head assembly 1 can include a head shell 11, a head body 12, and a socket 13.

  The head shell 11 may be removable from the housing shell 22. The head shell 11 may form the outside of the head assembly 1. The head shell 11 includes a plurality of branch members 111 circumferentially arranged around the central axis of the head shell 11, a plurality of support members 112 fixed to the PCB, and a bending member for fixing the head main body 12 And 113 may be included. The plurality of branch members 111 may be inserted inside the housing shell 22, and at least one of the plurality of branch members 111 may be in contact with the housing shell 22. The plurality of branch members 111 may have an outwardly curved shape so as to easily contact the housing shell 22. The plurality of support members 112 can include, for example, two support members 112 disposed on opposite sides of the central axis of the head shell 11.

  The head shell 11 can include a plurality of branch grooves 115 formed between the plurality of branch members 111, the plurality of branch grooves 115 having a first portion 115a having a width which increases downward, And a second portion 115b provided in a round shape recessed downward at the lower end of the first portion 115a. The shape of the branch groove 115 can reduce plastic deformation of the plurality of branch members 111.

  The bending member 113 may be a member projecting downward. The bending member 113 may be bent inward after the head body 12 is mounted inside the head shell 11. The inwardly bent bending member 113 can prevent the head main body 12 from being separated from the head shell 11.

  The head body 12 may be mounted inside the head shell 11. The central axis a of the head body 12 may coincide with the central axis of the head shell 11. The head body 12 may support the socket 13. The head body 12 can include a head side 121 to be inserted into the inner wall of the head shell 11, a head upper portion 122 formed on the upper side of the head side 121, and an insertion groove 125. . The head upper portion 122 can include, at its center, a hole into which the central pin 24 is inserted. The insertion groove 125 may be formed below the head side 121.

  The socket 13 may be removable from the head body 12. The socket 13 may include a plurality of contact members 131, a fixing portion 132, and an insertion member 135.

  The fixing portion 132 may have a shape corresponding to the inner wall of the head body 12 or may be fixed to the inner wall of the head body 12.

The plurality of contact members 131 may be formed of a conductive material that can be electrically connected to the central pin 24 and may have a shape that is bent toward the central axis a of the head body 12. For example, the plurality of contact members 131 may include a central portion having a shape bent inward more than the upper or lower portion thereof. The plurality of contact members 131 may have elasticity. When an external force is applied to the plurality of contact members 131, the plurality of contact members 131 may be deformed around the fixing portion 132. The central pin 24 may push the plurality of contact members 131 outward while the central pin 24 is inserted into the head assembly 1. For example, as shown in FIG. 3, when the central pin 24 is inserted into the head assembly 1 while being biased in the x-axis direction, the contact member 131 may be deformed outward around the fixing portion 132.
Furthermore, as shown in FIG. 4, even if the central pin 24 is inserted into the head assembly 1 in a state of being biased in the y-axis direction, the contact member 131 can be deformed outward around the fixing portion 132 .

  The plurality of contact members 131 may be disposed circumferentially around the central axis a of the head body 12. Although FIGS. 3 to 5 show four contact members 131, the number of the plurality of contact members 131 may be “4” or more. For example, the plurality of contact members 131 may be disposed at predetermined intervals. Each of the plurality of contact members 131 may include a first extension 1311, a second extension 1312, and a third extension 1313.

  The first extension portion 1311 may extend upward from the fixing portion 132 and may be inclined toward the central axis a of the head main body 12. That is, the separation distance between the first extension 1311 and the head side 121 of the head body 12 may increase toward the top of the first extension 1311. The first extension 1311 may be an elongated member. The first extension 1311 allows the central pin 24 and the contact member 131 to easily contact each other even when the central pin 24 is not inserted along the central axis a of the head body 12 obtain.

  The second extension 1312 may extend upwardly from the first extension 1311 and may be inclined towards the inner wall of the head body 12. That is, the separation distance between the second extension 1312 and the central axis a of the head body 12 may increase toward the top of the second extension 1312. The second extension 1312 may be an elongated member. The second extension 1312 can guide the central pin 24 toward the central axis a of the head body 12 even when the central pin 24 is not inserted along the central axis a of the head body 12 it can. The second extension 1312 can prevent the central pin 24 from being restricted from being inserted inside the socket 13 when it is caught by the contact member 131.

  The connection between the first extension 1311 and the second extension 1312 may be arranged closer to the central axis a of the head body 12 than to another part of the socket 13. The connection may contact the central pin 24. The contact member 131 and the central pin 24 may be electrically connected via the connection portion. The connection is shown in the top view of the head assembly 1. Referring to the top view of the head assembly 1, the connection parts may be closely arranged. The distance between the connection portions of adjacent contact members 131 may be smaller than the width of central pin 24. As a result, even when the central pin 24 is inserted out of alignment with the central axis a of the head body 12, at least one of the plurality of contact members 131 may contact the central pin 24.

The third extension 1313 may extend upward from the second extension 1312 and may be inclined in a direction from the second extension 1312 toward the central axis a of the head body 12. That is, the third extension 1313 can be considered to be inclined toward the central axis a of the head main body 12 with respect to the virtual extension of the second extension 1312. The separation distance between the upper end of the third extension 1313 and the central axis a of the head body 12 is equal to or greater than the separation distance between the lower end of the third extension 1313 and the central axis a of the head body 12 Good. For example, the third extension 1313 may approach the inner wall of the head body 12 from the lower end to the upper end. In another example, the third extension 1313 may be parallel to the inner wall of the head body 12. In an example in which the third extension 1313 is not formed, the sharp end of the second extension 1312 may contact the inner side wall of the head body 12 and damage this inner wall of the head body 12.
However, in the example where the third extension 1313 is formed as shown in FIG. 3, such concern may be prevented. Furthermore, as compared with the example in which the second extension 1312 extends to the height of the third extension 1313, the third extension 1313 greatly expands the range of angles at which the contact member 131 deforms around the fixing portion 132. can do. That is, when the contact member 131 is designed to have a predetermined range of deformation angle, the width of the internal space of the head body 12 can be reduced. As a result, the strength of the head body 12 can be improved by reducing the overall size of the head body 12 or conversely by increasing the thickness of the head body 12.

  The third extension 1313 may be disposed closer to the central axis a of the head main body 12 than the fixing portion 132. With the above structure, it is possible to design the third extension 1313 so as not to contact the inner wall of the head body 12 even when the contact member 131 is deformed outward.

  When the contact member 131 is not under pressure by the central pin 24, the upper end of the third extension 1313 may be separated from the upper inner wall of the head body 12 by the distance L. According to the above-described structure, it is possible to prevent the third extension 1313 from receiving the interference of the upper inner wall of the head main body 12 while the contact member 131 is deformed outward. When the contact member 131 receives pressure by the central pin 24, the upper end of the third extension 1313 may approach the upper inner wall of the head body 12.

  The inner side of the third extension 1313 may be closer to the central axis a of the head body 12 than the inner side of the head body 12. Here, the inside of the head body 12 may point to the inside of the head upper part 122. For example, the inside of the third extension 1313 may be closer to the central axis a of the head body 12 by a distance d than the inside of the head body 12. With the above structure, the third extension 1313 can stably guide the central pin 24 to the inside of the socket 13.

  The insertion member 135 may be formed below the fixing portion 132. The insertion member 135 extends toward the lower portion of the fixing portion 132 and may be bent outward twice, so that it has a shape parallel to the fixing portion 132. The insertion member 135 may be inserted into the insertion groove 125. Since the insertion member 135 is inserted into the insertion groove 125, the socket 13 can be stably mounted on the head body 12.

  If necessary, a suction cap c may be mounted on the top of the head assembly 1.

  FIG. 3 shows a state in which the central pin 24 is connected to the socket 13 in a state of being offset from the central axis a of the head body 12, and FIG. 5 shows the socket along the central axis a of the head body 12. 13 shows a state of being connected.

  The distance between the facing contact members 131 may be smaller than the diameter D2 of the central pin 24. When central pin 24 is connected to socket 13 along central axis a of head body 12, central pin 24 may contact all of at least four contact members 131. The central pin 24 maintains contact with all of the at least four contact members 131 so that the electrical connection between the central pin 24 and the contact members 131 can be stably ensured.

  When the central pin 24 is connected to the socket 13 off the central axis a of the head body 12, the central pin 24 can contact at least two of the at least four contact members 131. The at least two contact members 131 may be contact members adjacent to each other. In the example of FIG. 3, when the central pin 24 is shifted in the −x direction, the central pin 24 may be separated from the contact member 131 disposed in the + x direction. Also in this example, the central pin 24 can contact the contact members 131 disposed in the −x direction, the + y direction, and the −y direction.

  As the number of contact members 131 in contact with the central pin 24 increases, the electrical connection between the central pin 24 and the socket 13 can be realized more stably. When central pin 24 is connected to socket 13 in the proper position, central pin 24 can contact all of at least four contact members 131. Furthermore, when the central pin 24 is offset in the x-axis or y-axis direction, the central pin 24 can contact at least three contact members 131. Furthermore, when the central pin 24 is offset between the x-axis direction and the y-axis direction, the central pin 24 can contact at least two contact members 131.

  On the other hand, the distance D1 between two adjacent ones of the at least four contact members 131 may be smaller than the diameter D2 of the central pin 24. In that case, even when the central pin 24 is shifted between the two adjacent contact members 131, the central pin 24 can be stably connected to the two adjacent contact members 131.

  The head body 12 can include a circular inlet 122a through which the central pin 24 passes. The central pin 24 may be connected to the socket 13 through the inlet 122a. The radius R of the inlet 122a may be equal to or greater than the radius of the central pin 24, ie half the D2 plus the maximum length of offset of the central pin 24. The displacement length D3 of the central pin 24 may be determined to be the distance between the central axis of the central pin 24 and the central axis a of the head body 12. In this case, the maximum length of offset may refer to the maximum distance the central pin 24 can be structurally spaced from the central axis a of the head body 12 while the head assembly 1 is connected to the housing assembly 2. Yes (see Figure 1). The radius R of the inlet 122a can be equal to or greater than the radius of the central pin 24, that is, the sum of half of D2 and the maximum length of the offset of the central pin 24, so that the central pin 24 It is possible not to get caught at the entrance 122a.

  On the other hand, when the housing assembly 2 and the head assembly 1 are connected, the head shell 11 may be disposed inside the housing shell 22. When the central pin 24 is connected to the socket 13 along the central axis a of the head body 12, the distance between the head shell 11 and the head body 12 may be greater than or equal to the maximum length of offset of the central pin 24 . According to the above-described structure, even if the displacement of the central pin 24 is maximum, the head shell 11 can be prevented from contacting the head main body 12, and as a result, the possible displacement length of the central pin 24 is not limited. You can do so.

  In step 930, the cut plate 139 may be bent along the plurality of fold lines 81, 82, 83, 84, and 85. The plurality of folding lines 81, 82, 83, 84 and 85 are for forming the first to third folding lines 81, 82 and 83 for forming the plurality of contact members 131 and the insertion member 135. And fourth and fifth fold lines 84 and 85, respectively.

  Plate 139 may be bent in a first direction along a first fold line 81 to form a first extension 1311. Plate 139 may be bent in a second direction along a second fold line 82 to form a second extension 1312. The second direction may be opposite to the first direction. The plate 139 may be bent again in the first direction along the third fold line 83 to form a third extension 1313. The first extension 1311, the second extension 1312, and the third extension 1313 of each of the plurality of contact members 131 may be formed through bending the plate 139 three times, in this case, Work can be done quickly. Similarly, plate 139 may be bent along fourth and fifth fold lines 84 and 85 to form insert 135.

  At step 940, the left end and the right end of the plate 139 may be joined by rolling the plate 139. For example, the left end 132a and the right end 132b of the fixing portion 132 may be in contact with each other.

  The method of manufacturing the socket for the connector assembly may further include, for example, bending 910 the plate 139 along the plurality of fold lines 81, 82, 83, 84 and 85 before cutting the plate 139. it can.

  In step 910, the plate 139 having a planar shape may be bent along the plurality of fold lines 81, 82, 83, 84, and 85.

And fourth and fifth fold lines 84 and 85, respectively.

  At step 920, the open plate 139 may be cut to form a plurality of contact members 131, anchors 132, and inserts 135. Since the bent plate 139 is not easy to cut, the plate 139 may be cut open to facilitate the operation.

  At step 930, the cut plate 139 may be bent along a plurality of fold lines. The cut plate 139 may be bent again along the fold line where the plate 139 has already been bent at step 910. Since plate 139 has already been bent once, plate 139 can be easily bent with less force.

  At step 940, the left end and the right end of the plate 139 may be joined by rolling the plate 139. For example, the left end 132a and the right end 132b of the fixing portion 132 may be in contact with each other.

  Referring to FIG. 8, the first extension 1311 may have a shape that gradually narrows upward. According to the above-described shape, even when the plurality of contact members 131 are inclined upward toward the central axis of the head main body 12, it is possible to prevent adjacent contact members 131 from overlapping.
