Referring to fig. 5 to 8, the opening 121 of the insulating housing member 1 has a first inner wall surface 121a and a second inner wall surface 121b facing each other along the up-down direction D2 and corresponding to the first surface 21 and the second surface 22 of the circuit board 2, respectively. The insulating housing 1 further has two first protrusions 19a protruding from two ends of the first inner wall surface 121a toward the first surface 21, and two second protrusions 19b protruding from two ends of the second inner wall surface 121b toward the second surface 22, wherein the two first protrusions 19a and the two second protrusions 19b are used to limit the circuit board 2, so that the first inner wall surface 121a and the second inner wall surface 121b of the opening 121 and the first surface 21 and the second surface 22 of the circuit board 2 keep at least a predetermined distance d, in other words, the protruding length of the two first protrusions 19a and the two second protrusions 19b is equal to the predetermined distance d. In detail, the differential signal terminal pairs 26 of the circuit board 2 are not only kept at least the predetermined distance D from the first inner wall surface 121a and the second inner wall surface 121b of the opening 121, but also the positions of the differential signal terminal pairs 26 are also shifted from the two first protrusions 19a and the two second protrusions 19b in the left-right direction D3, thereby reducing the influence of the insulating case member 1 on the quality of the transmission signals of the terminals on the circuit board 2. The predetermined distance d is, for example, at least 0.6mm, but is not limited thereto.

Furthermore, in the first embodiment, the cross sections of the two first protruding portions 19a and the two second protruding portions 19b are rectangular, each first protruding portion 19a has a first limiting surface 19c facing the first surface 21 of the circuit board 2 to limit the circuit board 2 and being planar, and each second protruding portion 19b has a second limiting surface 19d facing the second surface 22 of the circuit board 2 to limit the circuit board 2 and being planar. It should be noted that the cross-sections of the two first protrusions 19a and the two second protrusions 19b may also be other shapes, such as a circle or other kinds of polygons, and in other embodiments, the two first protrusions 19a and the two second protrusions 19b may also limit the circuit board 2 by a limiting point (for example, when the first protrusions 19a and the second protrusions 19b are in a hemispherical structure) or a limiting line (for example, when the first protrusions 19a and the second protrusions 19b are in a wavy structure), which is not limited by the first embodiment. In addition, referring to fig. 9, in a modified embodiment, a rounded corner structure F1 (or a rounded corner structure (not shown)) may be further formed between the first protrusion 19a and the first inner wall surface 121a, and a rounded corner structure F2 (or a rounded corner structure (not shown)) may be further formed between the second protrusion 19b and the second inner wall surface 121 a.

It should be noted that the distance between the two first limiting surfaces 19c and the two second limiting surfaces 19d may be slightly greater than the thickness of the circuit board 2, so as to avoid the situation of difficult assembly.

Referring to fig. 1 to 4, the insulating housing 1 further has a setting groove 141 disposed on the top setting surface 14 and located on the positioning plate 15, and two limiting blocks 142 protruding upwards and inwards from the top setting surface 14 and located above the left and right sides of the setting groove 141. The locking element 4 is an independent metal element connected to the insulating housing 1 in an assembled manner and correspondingly disposed in the setting groove 141 of the positioning plate 15 in the first embodiment, the locking element 4 has a connecting section 41 disposed in the setting groove 141 and connected to the insulating housing 1, the connecting section 41 has a setting portion 411 disposed at a wider bottom of the setting groove 141, and a connecting portion 412 extending from a front end of the setting portion 411 in a bending manner. The setting groove 141 is provided with two engaging blocks 141a protruding upward at intervals left and right, and the setting portion 411 is formed with two engaging holes 411a engaging with the two engaging blocks 141a, so that the setting portion 411 of the locking device 4 can be stably fixed in the setting groove 141 of the insulating housing member 1. However, it should be noted that, in other embodiments, the connecting section 41 of the locking element 4 may be integrally connected to the insulating casing element 1, and the present embodiment is not limited thereto.

The locking member 4 further has a locking section 42 extending rearward from the connecting portion 412 of the connecting section 41 and spaced apart from the insulating housing member 1, and an actuating section 43 extending upward and rearward from a rear end of the locking section 42. Since the connecting portion 412 of the connecting section 41 can be elastically bent and deformed, the locking section 42 can be elastically moved downward. The locking segment 42 is formed with two locking blocks 421 at the top surface for locking with two locking holes (not shown) of the mating connector 100. When the actuating section 43 is pressed downward to drive the locking section 42 to move downward elastically, the locking block 421 of the locking section 42 can be disengaged from the locking hole of the mating connector 100 for unlocking. In addition, the locking segment 42 is further formed with two limiting strips 422 extending backward from the left and right sides and respectively limited by the two limiting blocks 142 in the upward direction, thereby limiting the maximum height of the locking segment 42 and further preventing the locking element 4 from being disengaged.

Referring to fig. 10 to 12, a second embodiment of the connector 100 of the present invention is different from the first embodiment in that the two first protrusions 19a protrude from the rear sections of the two end portions of the first inner wall surface 121a toward the first surface 21, and the two second protrusions 19b protrude from the rear sections of the two end portions of the second inner wall surface 121b toward the second surface 22, so that the two first protrusions 19a and the two protrusions are less likely to be viewed from the front through the opening 121.

To sum up, the connector 100 of the present invention utilizes the two first protruding portions 19a and the two second protruding portions 19b of the insulating housing 1 to limit the circuit board 2, and at least keeps the predetermined distance d between the opening 121 of the insulating housing 1 and the first surface 21 and the second surface 22 of the circuit board 2, thereby reducing the influence of the insulating housing 1 on the quality of the transmission signals of the terminals on the circuit board 2.

However, the above embodiments are only examples of the present invention, and the scope of the present invention should not be limited thereto, and all the simple equivalent changes and modifications made according to the claims and the contents of the patent specification should be included in the scope of the present invention.
