AI Technical Summary
Conventional connectors face challenges in dimensional control and deformation due to heating during reflow soldering, particularly in surface mount products where different materials and elements require precise alignment and grounding, leading to potential mounting defects.
The connector design includes an insulating first housing with a metal gland shell and surface mount terminals, where the terminals are aligned in a specific configuration to minimize deformation and facilitate dimensional control, with the ground shell being grounded through the terminals rather than direct surface mounting.
This configuration ensures easier dimensional control and reduces deformation effects during reflow soldering, maintaining consistent alignment and functionality of the connector components.

Abstract
Description
Technical Field
[0001] The present disclosure relates to the structure of a connector.
Background Art
[0002] As a prior art of connectors, there is an improved one for high-speed data transmission connection that minimizes impedance discontinuity through the connector (see, for example, Patent Document 1). FIG. 11 is a diagram showing the rear end of a female connector which is a board-side connector in the prior art. FIG. 12 is a perspective view showing the female connector of FIG. 11 for surface mounting applications.
[0003] The prior art female connector 800 has an outer shell or outer wall 801, and a series of conductive terminals extend through this outer shell or outer wall 801. In this example, two sets of "triangles" (triplets) are shown, and each triplet includes a ground terminal 802 and two associated signal terminals 810, 811. Other terminals such as a power supply terminal 820 and a status terminal 821 can also be included. All of these terminals are inserted into the connector from the rear end, and a suitable insulating material is molded around these terminals to form the connector.
[0004] The ground terminal 802 shown in FIG. 11 has a contact or bonding blade portion 804 that extends in a cantilever shape from a terminal body or body portion 805, and the body portion 805 extends to a mounting portion. The mounting portion is a surface mounting leg portion 807 or a through-hole member 806. In this type of connector structure, the width of the ground terminal 802 in the female connector 800 increases from the body portion 805 as shown by 803 to provide a large surface area for the ground terminal 802, and exists in the same direction as the two associated signal terminals 810, 811. FIG. 11 shows the female connector 800 of FIG. 10 for surface mounting applications, and the body portion 805 of the ground terminal 802 with an increased width is aligned with the body portions 812 of the signal terminals 810, 811 so as not to unduly increase the overall size and "footprint" of the female connector 800 (see Patent Document 1, paragraphs
[0060] -
[0062] ). [Prior art documents] [Patent Documents]
[0005] [Patent Document 1] Japanese Patent Publication No. 2005-5272 [Overview of the Initiative] [Problems that the invention aims to solve]
[0006] Connectors for high-speed signal connections may require shielding components (noise shielding components) such as shield shells (like the outer shell or outer wall 801) or ground shells. Surface mount products require these shielding components to be grounded to the circuit board by surface mounting. To achieve surface mounting, it is necessary to arrange the surface mount parts of these multiple components on the same surface (mounting surface). In the conventional female connector 800, as shown in Figure 12, although the width of the ground terminal 802 is different, it extends directly from both ends of the outer shell or outer wall 801 and is configured to have a shape similar to the surface mount legs 807.
[0007] However, conventional techniques, as shown in Figure 12, have the problem that it is difficult to control the dimensions of each element constituting the connector, and because the materials are different, the deformation due to heating during reflow soldering can also differ for each element, making it easy for mounting defects to occur.
[0008] In view of the above issues, this disclosure aims to provide a connector that facilitates dimensional control and suppresses the effects of deformation due to heating during reflow assembly. [Means for solving the problem]
[0009] To solve the above problems, the connector according to this embodiment comprises: an insulating first housing that can be mounted on a circuit board and has a first surface having a first width and a first hole that penetrates between the first surface and a second surface different from the first surface; a metal gland shell that is housed in the first hole and formed in a predetermined shape such that a second hole is formed that penetrates between the first end on the first surface side and the second end on the second surface side; and a plurality of surface mount terminals, each having a mounting portion at one end that extends in a first direction toward the first housing and can be surface mounted on a circuit board, and an insertion portion at the other end in which at least a part of the insertion portion is housed in the second hole. The gland shell is formed such that a part of it abuts against the insertion portion of a predetermined surface mount terminal among the plurality of surface mount terminals. The plurality of surface mount terminals are positioned such that the ends of the mounting portion opposite to the first direction side and the ends of the insertion portion on the first direction side are aligned in the width direction of the first width. [Effects of the Invention]
[0010] The connector of this embodiment facilitates dimensional control and suppresses the effects of deformation due to heating during reflow soldering. [Brief explanation of the drawing]

[0012] Embodiments of this disclosure will be described below with reference to the drawings. In the following description, components having the same function will be numbered the same, and redundant explanations will be omitted.
[0013] Figure 1 shows an embodiment of the connector according to this embodiment. Figure 1A is a perspective view taken from above on the rear side, and Figure 1B is a front view. Figure 2 is a perspective view taken from above on the rear side when the connector 100 is disassembled.
[0014] One embodiment of the connector of the present disclosure, the connector 100, includes a first housing 1, a second housing 2, a ground shell 3, in this example, nine surface mount terminals 4 (surface mount terminals 4-1, 4-2, …, 4-9), and a shield shell 5. Each of the insertion portions 43 of the surface mount terminals 4 is inserted into the holes 25a, 25b of the second housing 2 inserted into the second hole portion 36 of the ground shell 3. The second housing 2 with the surface mount terminals 4 inserted therein and the ground shell 3 are inserted into the first hole portion 13 of the first housing 1. The shield shell 5 is attached to the first housing 1 so as to cover the upper surface and the side surface of the first housing 1. In the connector 100 of this example, the first housing 1, the mounting portions 41 of the surface mount terminals 4, and the mounting portions 52c, 53c of the shield shell 5 are mounted on the surface of a circuit board not shown, and the connector 1 is surface-mounted via reflow.
[0015] (First housing 1) FIG. 3 is a view showing the first housing 1. A in FIG. 3 is a perspective view seen from above on the front side, B in FIG. 3 is a front view, and C in FIG. 3 is a rear view. The first housing 1 is a substantially box-shaped insulating case for accommodating the second housing 2 with the ground shell 3 attached. The first housing 1 is formed of an engineering plastic such as LCP or PPS, for example.
[0016] The first housing 1 is a box-shaped case having a width W1 (hereinafter also referred to as “first width W1”), and is an insulating case that can be surface-mounted on a circuit board. The first housing 1 has a first accommodating portion 11, a peripheral wall portion 12, and shell receiving portions 16, 17.
[0017] The first housing section 11 has a first surface 11a having a first width W1, and a second surface 11b, which is on the opposite side of the first surface 11a in this example and is different from the first surface 11a. The first housing section 11 has a first hole 13 that penetrates between the first surface 11a and the second surface 11b. The first hole 13 is composed of a first hole 13a and a first hole 13b. That is, in this example, the first hole 13 has a first hole 13a, which is a rectangular opening slightly smaller than the outer shape of the first surface 11a, up to a certain point from the first surface 11a to the second surface 11b. From the end of the first hole 13a on the second surface 11b side to the second surface 11b, a first hole 13b, which is a rectangular opening smaller than the first hole 13a, is formed. The thickness of the upper wall (the wall on the +z direction side) of the first hole 13b is formed to be the same as the thickness of the upper wall of the first hole 13a up to the second surface 11b. As a result, a groove 15b is formed on the upper side of the second surface 11b of the first housing 11. The groove 15b contributes to the weight reduction of the first housing 1. The thickness of the bottom wall (the wall on the -z direction side) of the first hole 13b is formed to be thicker than the thickness of the bottom wall of the first hole 13a and extends toward the second surface 11b. However, the bottom wall of the first hole 13b does not extend to the second surface 11b, but in this example it is formed to extend to about one-third the length of the upper wall of the first hole 13b. As a result, a groove 15a is provided on the lower side of the second surface 11b of the first housing 11. By providing the groove 15a, space can be secured to insert the surface mount terminal 4, which has a portion formed to bend due to the mounting portion 4 and the rise portion 42 (see Figure 7), further in (towards the first surface 11a side). By providing the groove 15b, the weight of the first housing 1 can be reduced, and the upper wall portion of the first hole 13b is positioned to cover a part of the mounting portion 41 and the rise portion 42 of the surface mount terminal 4, protecting the surface mount terminal 4 from being easily touched from the outside.
[0018] The peripheral wall portion 12 is formed as a U-shaped wall portion with an open bottom so as to cover the outer circumference of the end of the first surface 11a side of the first housing portion 11. The peripheral wall portion 12 guides the edge of the shield shell 5 on the peripheral wall portion 12 side so as not to move outward in the depth direction (-y direction) from the peripheral wall portion 12 when the shield shell 5 is mounted so as to cover the first housing 1.
[0019] The shell receiving sections 16 and 17 are provided on the lower side (-z direction side) of both sides of the first housing section 11. The shell receiving sections 16 and 17 are each composed of a pair of box-shaped sections. The shell receiving section 16 accommodates the insertion sections 52a and 52b of the shield shell 5, and the shell receiving section 17 accommodates the insertion sections 53a and 53b of the shield shell 5. The shell receiving sections 16 and 17 have grooves 16a, 16b and 17a, 17b formed from the upper surface to the lower surface (Figures 1 and 3). The grooves 16a and 16b receive the insertion of the insertion sections 52a and 52b. The grooves 17a and 17b receive the insertion of the insertion sections 53a and 53b.
[0020] The peripheral wall portion 12 and the shell receiving portions 16, 17 determine the position of the shield shell 5 relative to the first housing 1, and the surface mounting positions of the mounting portions 52c, 53c are determined.
[0021] (2nd Housing 2) Figure 4 shows the second housing 2. Figure 4A is a perspective view from above the front, Figure 4B is a front view, and Figure 4C is a rear view. The second housing 2 is a roughly box-shaped insulating case for positioning the surface mount terminals 4 housed within the ground shell 3. The second housing 2 is formed from an engineering plastic such as LCP or PPS.
[0022] In this example, the second housing 2 is a box-shaped case having a width W2 (hereinafter also referred to as "second width W2") that is slightly smaller than the width of the first hole 13b of the first housing 1, and is an insulating case that can be housed in the first hole 13b. The second housing 2 is housed in the ground shell 3. The second housing 2 is an insulating case housed in the second hole 36 (see Figure 5) of the ground shell 3. The second housing 2 has a second housing portion 21 and a peripheral wall portion 22.
[0023] The second housing section 21 has a surface 21a having a second width W2, and in this example, a surface 21b opposite to surface 21a, which is different from surface 21a (the surface outside the rear wall 215, which will be described later). The second housing 2 has an opening 23. The opening 23 has a rectangular opening that is slightly smaller than the outer shape of surface 21a, and is formed to be shorter in length than the insertion sections 43A, 43B (see Figure 7) from surface 21a to surface 21b, and the surface 21b side (rear side) is closed by the rear wall 215.
[0024] The peripheral wall portion 22 is formed as an annular wall portion on the outer circumference of the end of the second housing portion 21 on the surface 21a side. The peripheral wall portion 22 guides the opening (edge) on the surface 21a side of the ground shell 3 so that it cannot move outward in the depth direction (-y direction) from the peripheral wall portion 22 when the ground shell 3 is fitted so as to enclose the outer circumference of the second housing portion 21 (i.e., when the second housing 2 is fitted into the second hole portion 36 of the ground shell 3).
[0025] The second housing 2, having a peripheral wall portion 22, is housed in the second hole portion 36 of the ground shell 3. The second housing 2, housed within the ground shell 3, is integrated with the ground shell 3 and housed in the first hole portion 13 of the first housing 1.
[0026] The second housing section 21 has grooves 24a and 24b. The grooves 24a and 24b are formed on the upper surface (surface 2111) and lower surface (surface 2141) within the opening 23 of the second housing section 21 so that the surface mount terminals 4 are positioned in appropriate locations that allow for electrical connection with the terminals of the mating connector. The grooves 24a and 24b are formed as grooves with a width that allows the surface mount terminals 4 to be positioned in close contact. As shown in Figure 4B, the grooves 24a and 24b are arranged in a staggered pattern from the lower surface (surface 2141) to the upper surface (surface 2111). In this example, the second housing 2 has five grooves 24a on the surface 2141 side and four grooves 24b on the surface 2111 side.
[0027] Each groove 24a, 24b penetrates the rear wall 215 to form a hole. That is, the rear wall 215 is provided with holes 25a, 25b into which surface mount terminals 4 can be inserted. The holes 25a, 25b are connected to the grooves 24a, 24b. The holes 25a, 25b function as guides for correctly positioning the surface mount terminals 4 in the grooves 24a, 24b. In other words, the second housing 2 has grooves 24a, 24b, which are positioning parts corresponding to each insertion part 43 (43A, 43B) (see Figure 7), so that each insertion part 43 (43A, 43B) is positioned at a predetermined distance from each other within the second hole 36. In this example, the surface mount terminals 4 are inserted and press-fitted into the second housing 2 from the surface 21b side.
[0028] (Grand Shell 3) Figure 5 shows the ground shell 3. Figure 5A is a perspective view from above on the front side, and Figure 5B is a front view. Figure 6 shows the ground shell 3. Figure 6A is a cross-sectional view along line BB shown in Figure 5B. Figure 6B is a bottom view.
[0029] The ground shell 3 is a hollow, box-shaped case designed to block noise. The ground shell 3 is also a component that requires grounding to the circuit board. The ground shell 3 is made of a metal such as phosphor bronze.
[0030] The Grand Shell 3 in this example has a bottom wall portion 31, a side wall portion 32 connected to the bottom wall portion 31, an upper wall portion 33 connected to the side wall portion 32, a side wall portion 34 connected to the upper wall portion 33, and a bottom wall portion 35 connected to the side wall portion 34. The Grand Shell 3 in this example is constructed by bending a single thin metal plate to form a hollow box shape with a width W3 and a depth D31. However, the bottom wall portions 31 and 35 have a depth D32 that is shorter than the depth D31. The Grand Shell 3 has a recess 3a1 formed at the end of the bottom wall portion 31 and a protrusion 3b1 formed at the end of the bottom wall portion 35 that are fitted together to form an annular hollow box shape as a whole. In this example, the ground shell 3, together with the second housing 2, is housed in the first hole 13 of the first housing 1 and is box-shaped such that a second hole 36 is formed that penetrates between the first end 3A, which is the end on the first surface 11a side, and the second end 3B, which is the end on the second surface 11b side.
[0031] The ground shell 3 has contact portions 301 and 302. The contact portions 301 and 302 are formed on the inner surfaces of the bottom wall portions 31 and 35, and are surfaces 311 and 351 which constitute a part of the shape of the ground shell 3. One end of the contact portions 301 and 302 is fixed in connection with surface 311 or surface 351, and the other end is located inside the second hole portion 36.
[0032] The contact portions 301 and 302 are cantilevered beams with one end connected to the ground shell 3, and in this example, they extend in the +z and -y directions. The free end sides (ends 301b and 302b) of the contact portions 301 and 302 are formed by bending them so that they face downward (-z direction) near their tips. In this disclosure, the points on the contact portions 301 and 302 that come into contact with the surface mount terminals 4-1 and 4-9 are referred to as "contact points P" (see Figure 9). The widths of the fixed end sides 301a and 302a and the free end sides 301b and 302b of the contact portions 301 and 302 may be the same or different. In this example, the contact portions 301 and 302 are formed so as to further strengthen the fixing of the ends 301a and 302a, their width gradually decreases from the ends 301a and 302a toward the ends 301b and 302b, and then maintains a constant width from a certain point. In this example, the contact portions 301 and 302 are formed by punching out the bottom wall portions 31 and 35, thereby forming holes 31a and 35a in the punched-out areas.
[0033] The contact portions 301 and 302 are provided in positions that contact the insertion portions 43 of surface mount terminals 4-1 and 4-9, which are located on the outermost side in the width W1 direction among the nine surface mount terminals 4 in this example. The number of contact portions in this disclosure is not limited to this, and one or three or more may be provided. The position of the contact portions in this disclosure may be adjusted as appropriate in relation to the surface mount terminals 4. For example, it is not limited to a configuration that contacts the outermost surface mount terminal 4 in the width W1 direction, such as configuring it to contact the surface mount terminal 4 located in the central position in the width W1 direction.
[0034] In this example, the ground shell 3 is provided with insertion portions 32a and 34a on the lower side (-z direction side) of both sides of the ground shell 3, which protrude below the bottom wall portions 31 and 35, in order to facilitate positioning with respect to the circuit board. The insertion portions 32a and 34a have the function of press-fitting and holding the ground shell 3 into the first housing 1.
[0035] (Surface mount terminal 4) Figure 7 shows a surface mount terminal 4. Figure 7A is a perspective view from above on the rear side, and Figure 7B is a left side view. In this example, the surface mount terminal 4 has two different heights, so to distinguish them, one may be called the first surface mount terminal 4A and the other the second surface mount terminal 4B. In Figure 7, to facilitate understanding of the shape, two surface mount terminals 4 are shown, with one adjacent terminal each selected from the first surface mount terminal 4A and the second surface mount terminal 4B out of the nine surface mount terminals 4. The names of the parts of the surface mount terminal 4 may be identified by adding "A" or "B" to the end of each code, in accordance with the first surface mount terminals 4A and 4B.
[0036] Each of the multiple surface mount terminals 4 consists of a mounting portion 41 (mounting portions 41A, 41B), a riser portion 42 (riser portions 42A, 42B) connected to the mounting portion 41, and an insertion portion 43 (insertion portions 43A, 43B) connected to the riser portion 42. The surface mount terminals 4 are made of a conductive material such as phosphor bronze. In this example, the connector 100 is configured with a total of 9 surface mount terminals 4. In this disclosure, when identifying these 9 terminals, they will be referred to as surface mount terminals 4-1, 4-2, ..., 4-9 in order from left to right in the viewpoint of B in Figure 1. Here, surface mount terminals 4-1, 4-3, 4-5, 4-7, 4-9 are the first surface mount terminals 4A located on the lower part (surface 2141) of the second housing 2. Surface mount terminals 4-2, 4-4, 4-6, and 4-8 are second surface mount terminals 4B located on the upper side (surface 2111) of the second housing 2.
[0037] The mounting portion 41 (mounting portions 41A, 41B) extends in the first direction (the -y direction in Figure 7), which is the direction toward the first housing 1, and is a portion that can be surface-mounted on a circuit board (not shown). Each of the mounting portions 41 in this example is made up of the same size. In this example, each of the ends 41a (ends 41aA, 41aB) of the mounting portion 41 on the opposite side from the first direction (i.e., the +y direction side) is positioned to be aligned in the direction of the first width W1 (Figure 2). Ends 41aA and 41aB are aligned in a single line.
[0038] The rising portion 42 (rising portions 42A, 42B) is connected to the end portion 41b (end portion 41bA, 41bB), which is the end portion on the first direction side (-y direction side) of the mounting portion 41, and extends in the direction rising from the circuit board (in Figure 7, the +z direction, or the -y direction and +z direction).
[0039] The insertion portion 43 (insertion portions 43A, 43B) is connected to the extending end portion 42b (end portion 42bA, 42bB) of the rising portion 42 and extends in a first direction, with at least a part of it being accommodated in the second hole portion 36 of the ground shell 3. Each of the insertion portions 43 in this example is made up of the same size and shape. Each of the first-direction-side end portions 43b (end portions 43bA, 43bB) of the insertion portion 43 in this example is positioned to be aligned in the first width W1 direction (Figure 2). In this example, each of the end portions 43bA is aligned in a row, and each of the end portions 43bB is aligned in a row different from that of the end portions 43bA.
[0040] Surface mount terminals 4-2 to 4-8, other than surface mount terminals 4-1 and 4-9, are electrically connected to the mating connector. Surface mount terminals 4-1 and 4-9 are not electrically connected to the mating connector.
[0041] In this example, the surface mount terminal 4 consists of two types: a first surface mount terminal 4A whose rising portion 42 rises from the circuit board to a first height (H41), and a second surface mount terminal 4B whose rising portion 42 rises from the circuit board to a second height (H42) higher than the first height H41. Each of the first surface mount terminals 4A is made up of the same size and shape. Each of the second surface mount terminals 4B is made up of the same size and shape. When the surface mount terminal 4 is configured to be fixed to the second housing 2, the first surface mount terminal 4A has its end portion 43bA inserted through the hole portion 25a and a part of the insertion portion 43A is positioned in the groove portion 24a. The second surface mount terminal 4B has its end portion 43bB inserted through the hole portion 25b and a part of the insertion portion 43B is positioned in the groove portion 24b.
[0042] (Shield Shell 5) Figure 8 shows the shield shell 5. Figure 8A is a perspective view from above on the rear side, and Figure 8B is a rear view. The shield shell 5 is a thin metal plate that forms a U-shaped cross-section with the lower end being open, and is a noise shielding component. The shield shell 5 is a metal plate that covers the first housing 1 with the first hole 13 open (without blocking the first hole 13). The shield shell 5 is made of a metal such as brass. The shield shell 5 has an upper wall portion 51, a side wall portion 52, and a side wall portion 53. The upper wall portion 51 is a rectangular plate formed to cover the upper surface of the first housing 1. The side wall portion 52 is a substantially rectangular plate formed to cover the side surface of the first housing 1 by connecting to one end of the upper wall portion 51 in the width direction. The side wall portion 53 is a substantially rectangular plate formed to cover the side surface of the first housing 1 by connecting to the other end of the upper wall portion 51 in the width direction. The side wall portion 52 has insertion portions 52a and 52b on its lower side. Between insertion portions 52a and 52b, there is a mounting portion 52c for surface mounting onto a circuit board. The side wall portion 53 has insertion portions 53a and 53b on its lower side. Between insertion portions 53a and 53b, there is a mounting portion 53c for surface mounting onto a circuit board. The mounting portions 52c and 53c are formed to protrude outward in the width direction (x-axis direction) of the shield shell 5.
[0043] (Relationship between contact points 301, 302 and surface mount terminals 4-1, 4-9) Figure 9 is a cross-sectional view taken along line AA shown in Figure 1B. As shown in Figure 9, the connector 100 is configured such that when the surface mount terminal 4 is mounted in the second hole 36 of the ground shell 3, the surface mount terminal 4-1 contacts the contact portion 301. Although not shown in Figure 9, the surface mount terminal 4-9 is also configured to contact the contact portion 302. In Figure 9, the position of the contact portion 301 before contact with the surface mount terminal 4-1 is shown by a dotted line. The contact portions 301 and 302 contact the surface mount terminals 4-1 and 4-9, causing the contact point P to elastically displace downward (towards the -z direction). By the contact portions 301 and 302 contacting the surface mount terminals 4-1 and 4-9, the ground shell 3 becomes groundable via the surface mount terminals 4-1 and 4-9.
[0044] The ground shell 3 in the connector 100 of this disclosure is not configured to be grounded by itself. The contact portions 301 and 302 and the surface mount terminals 4-1 and 4-9 are not coupled to each other, but are in contact. The ground shell 3 becomes grounded via the surface mount terminals 4-1 and 4-9 because the contact portions 301 and 302 of the ground shell 3 are in contact with the surface mount terminals 4-1 and 4-9 that are grounded to the circuit board. In other words, the ground shell 3 is not surface-mounted to the circuit board. The part of the ground shell 3 that has the function of grounding is the mounting portion 41A of the surface mount terminals 4-1 and 4-9. Therefore, the same dimensional control as for the surface mount terminals 4-3, 4-5, and 4-7 is sufficient, making dimensional control easier. In addition, since surface mounting of the ground shell 3, which has a different material and shape from the surface mount terminals 4, is not required, it is not necessary to consider the effect of deformation of the ground shell 3 due to heating on the surface mount terminals 4.
[0045] In this disclosure, surface mount terminals 4-1 and 4-9 are all first surface mount terminals 4A, and have the same material, size, and shape as other first surface mount terminals 4A. Each mounting portion 41A is arranged in the same row. Each insertion portion 43A is arranged in the same row. Therefore, when the connector 100 is installed on a circuit board (not shown) and reflow mounted, even if the relative positional relationship between the insertion portion 43 and the contact portions 301 and 302 of surface mount terminals 4-1 and 4-9 is shifted, for example in the y-axis direction due to the effects of heat, the impact on the other surface mount terminals 4 is extremely limited.
[0046] In this disclosure, the first surface mount terminal 4A and the second surface mount terminal 4B are made of the same material, size, and shape, and are arranged in the same direction (y-axis direction), although the extension lengths of the riser portion 42A and the riser portion 42B are different. The mounting portion 41A and the mounting portion 41B are made of the same material, size, and shape, and are arranged in the same row. The insertion portion 43A and the insertion portion 43B are made of the same material, size, and shape, although their arrangement height (z-direction) is different because the extension lengths of the riser portion 42A and the riser portion 42B are different. Each insertion portion 43A is arranged in the same row. The insertion portion 43B is arranged in the same row as the insertion portion 43A, but its ends 43bA and 43bB are arranged in the y-axis direction. Therefore, even if the surface mount terminals 4A and 4B expand and deform due to the heat generated when the connector 100 is installed on a circuit board (not shown) and reflow-mounted, the impact on each other will be limited.
[0047] As described above, because the connector 100 has the above-described configuration, even if the relative positional relationship between the insertion portion 43 and the contact portions 301 and 302 of the surface mount terminals 4-1 and 4-9 is shifted, for example in the y-axis direction due to the effects of heat when the connector 100 is installed on a circuit board (not shown) and reflow mounted, the contact between the lower surface of the insertion portion 43 and the contact point P is maintained. Surface mount terminals 4-1 and 4-9 only require the same dimensional control as surface mount terminals 4-3, 4-5, and 4-7, making dimensional control easier. Furthermore, since surface mounting of the ground shell 3 is unnecessary, there is no need to consider the effect of deformation of the ground shell 3 due to heating on the surface mount terminals 4. The effect of expansion of the second surface mount terminal 4B on the surface mount terminal 4A is also extremely limited. Therefore, the connector 100 of this disclosure makes dimensional control easier and suppresses the effects of deformation due to heating during reflow mounting.
[0048] (modified version) Figure 10 shows an example of a modified connector according to this embodiment. The difference between the connector 100B according to this modified form and the connector 100 is that the shield shell 5 of the connector 100 has been replaced with a shield shell 5B. In the shield shell 5B, the mounting portions 52c and 53c that are mounted on the substrate of the shield shell 5 have been replaced with mounting portions 52d and 53d (53d is not shown) that are inserted into predetermined holes provided in the circuit board. Even in the connector 100B equipped with the shield shell 5B, the effects of deformation due to heating during reflow mounting can be suppressed.
[0049] The embodiments of the cable harness of this disclosure and its modifications have been described above. The shape of the connector 100 of this disclosure is merely an example. For example, the ground shell 3 is not limited to a box shape, and may be made up of other predetermined shapes, such as a combination of plate shapes or a U-shaped plate, as long as it does not deviate from the spirit of this disclosure. Also, although the first housing 1 described in this disclosure has a rectangular box shape, this is merely an example, and its shape may be appropriately changed to match the shape of the ground shell 3 for inserting the surface mount terminals 4. The connector 100 of this disclosure has nine surface mount terminals 4, but the number of surface mount terminals 4 is not limited to this and may be appropriately adjusted depending on the type of connector. Also, although this disclosure describes an example in which the surface mount terminals 4 are composed of two types, a first surface mount terminal 4A and a second surface mount terminal 4B, the surface mount terminals 4 are not limited to this. That is, they may all be of the same type, or they may be composed of three or more types.
[0050] Furthermore, it goes without saying that the surface mount terminals 4 and contact portions 301 and 302 described in this embodiment can be modified as appropriate without departing from the spirit of this disclosure. [Explanation of symbols]
