However, the guiding plate 101 is fixed structure, so when a thin circuit board is inserted into the slot, it will shake, which affects the stability of the high frequency system, and when the circuit board is a little bigger, it can not be inserted into the slot, which is a common disadvantage of the conventional slot-type electrical connector.
Accordingly, the related art proposes an improved technical solution (as shown in fig. 2) of the clamping structure, in which an ejector 20 is pivoted at the end of the slot 10, the ejector 20 is shaped like , two sides of the front end of the ejector are respectively provided with a groove 201, the bottom of each groove 201 is convexly provided with a clamping elastic sheet 202, when the circuit board is inserted into the slot, the ejector 20 can be pressed and pulled downwards to tilt upwards, and the two clamping elastic sheets 202 clamp and fix the circuit board. However, the conventional slot-in electrical connector with the ejector 20 also has the problem that the two clamping spring plates 202 of the ejector 20 cannot effectively perform their clamping function (i.e. there is a clearance and the occurrence of looseness) due to the difference between circuit board manufacturers and the thickness and size error of the circuit board; moreover, the ejector 20 has no support on the back of the two holding clips 202, and therefore is easily broken.
In addition, the current computer equipment has taken the design era of high frequency clock, so it is very easy to generate electromagnetic radiation during its operation, which usually affects the stability of the operation of the peripheral equipment, and the slot type electrical connector seen in the market at present has no preventive design for electromagnetic radiation (EMI), so the high frequency computer equipment, the component operation oscillation and the generated electromagnetic radiation interference are very easy to generate the loose insertion to affect its performance.

the socket 1 is a rectangular plastic strip, the top center of which is provided with a socket 11, one or both sides of the socket 11 are provided with terminals extending to the bottom, both sides of both ends of the socket 1 are respectively vertically upward formed with a support plate 12, the front edge of the inner plate wall of the support plate 12 is respectively protruded with a clamping block 121, the upper end of the inner side of the clamping block 121 is provided with an inclined plane 122 for guiding the circuit board to be inserted, the rear side is provided with an inward concave insertion slit 123, and the selected positions of the rear side plate walls of the two support plates 12 of the socket 1 are respectively provided with corresponding pivot holes 13, so that the ejector 2 is pivoted to the socket.
Referring to fig. 5, the ejector 2 can stably hold both side ends of the circuit board to allow a user to easily and quickly take out the circuit board, has a cross section in the form of an -shaped upright block, has a rectangular protruded plate 21 on the upper front edges of both side walls 20, and has a protruded holding portion on the lower front edges of both side walls 20, the holding portion being a trapezoidal top plate 25, a protruded strip 26 is provided on the inner wall of each top plate 25, a pressing block 22 is formed on the top of the ejector 2, a pivot post 23 is protruded from the outer bottom of both side walls 20, and a top block 24 protruded forward is provided in the center of the bottom.
Therefore, the pivot posts 23 at both sides of the two ejectors 2 are pivoted in the pivot holes 13 at both ends of the socket 1 (as shown in fig. 6 or fig. 10), so that the ejectors 2 are pivoted in the two support plates 12 at both ends of the socket 1, and the ejectors 2 can rotate, thereby forming the electric connector (as shown in fig. 3) for clamping the circuit board by the ejectors and the sockets.
In the usage of the present invention, when a user inserts a circuit board into the slot 11 of the slot seat 1 (as shown in fig. 6 and 7), the protruded top block 24 at the bottom of the ejector 2 can be pressed down to turn the ejector 2 inward, and at the same time, the top plates 21 on the upper front side of the ejector 2 are inserted into the slots 123 at the rear side of the clamping blocks 121 of the slot seat 1 (as shown in fig. 7 to 9), so that the backs of the top plates 21 are supported by the supporting plate 12, and the top plates 21 synchronously push and expand the inner surfaces of the clamping blocks 121 to move toward the center, so that the clamping blocks 121 clamp the circuit board 3; the two top plates 25 at the lower part of the front side of the ejector 2 can be directly clamped at the side of the bottom of the circuit board 3, and the raised strips 26 at the inner wall are used for supporting the side end of the circuit board 3 to prevent the circuit board from moving transversely, thereby achieving the effect of stable clamping.
The effect achieved by the utility model is that the two top sheets 21 of the ejector 2 are supported by the back surface of the supporting plate 12 of the slot seat 1, so that the top sheets 21 are not broken; the clamp block 121 extending to the inner side of the support plate 12 not only enhances the strength of the support plate 12, but also the back side of the clamp block 121 is provided with an inner concave insertion slit 123 to form an elastic contraction and expansion structure, so that when the top plate 21 is inserted, pushed and expanded, the circuit board 3 with various thickness tolerances can be stably clamped without breaking and damaging the circuit board; because of the clamping part of the front side of the lower part of the ejector 2, the two top plates 25 cooperate with the raised strips 26 to clamp and fix three sides of the circuit board 3, therefore, the structural design of the utility model can make the upper and lower parts of the two sides of the circuit board 3 all clamped firmly, further prevent the circuit board from shaking and loosening due to high-frequency oscillation, so that under the high-frequency operation of a computer system, the stability of the efficiency can be kept, and the stable effect of the clamping structure can be ensured at the same time.
When the user wants to take out the circuit board 3 (see fig. 6), the user can press the pressing block 22 at the top of the ejector 2 to turn the ejector 2 outwards, and simultaneously push the circuit board 3 out of the socket 1 by pressing the top block 24 at the bottom against the bottom edge of the circuit board 3, which is a common taking-out method and is not burdensome.
However, the present invention is not limited to the above embodiment because the structure of the circuit board 3 is designed to be stably clamped.
Referring to fig. 11, in order to illustrate the second embodiment of the present invention, the structure is substantially the same as that of the first embodiment, and the difference is: the clamping part at the lower front end of the two side walls 20 of the ejector 2 is pinned with the top plate 25 (see fig. 5), and the lower front end of the side walls 20 is provided with two insertion holes 27, so that an arc-shaped metal clamping piece 28 is inserted and fixed, and the lower front end of the ejector 2 becomes a clamping structure with two elastic clamping pieces; therefore, when the circuit board 3 is inserted into the socket 1, not only the clamping piece 28 can be used to clamp the two sides of the circuit board 3, but also the guiding portion 281 at the bottom edge of the clamping piece 28 can guide the static electricity out to maintain the stable effect of the computer system.
Therefore, the above embodiments are not intended to limit the scope of the present invention, and all such modifications and substitutions as are made by the same technical means of the present invention should be included within the scope and spirit of the present invention.
